The 2010iP station is a well-engineered system designed toprovide low-pressure sewerservice to individual residences orbuildings. Correct installation andstart-up of this equipment willensure proper operation.

This is a sewage handling pumpand must be vented inaccordance with national andlocal plumbing codes. This pumpis not to be installed in locationsclassified as hazardous. All pipingand electrical systems must be incompliance with applicablestandards, local and nationalcodes and to the satisfaction ofrelevant authorities.

PRODUCT DESCRIPTION

The 2010iP station consists ofa grinder pump, tank, pump alarmpanel and connecting power(supply) cable. The tank is apolyethylene basin complete witha gasket-sealed lid. Three lidstyles are available for the 2010iPstation (Figure 4). Sewage enters

the tank through the 100 mmDWV uPVC (110.2 mm OD)(standard) inlet pipe where it isground into fine particles by thegrinder pump. The in-line pumpingmechanism discharges themacerated sewage to a pressureor gravity main, then to a remotetreatment site. The pump is asemi-positive displacement typecapable of operating at dischargepressures up to 56 m TDH. Ampletank storage capacity inconjunction with integral levelsensing controls provides foreconomic, on-demand, operationof the grinder pump.

INSTALLATION STEPS

The following instructions willprovide the necessary informationto properly install the 2010iPstation.

1. Station Unpacking(Figure 1)

The station alarm panel, grinderpump and tank are shipped to thejob site separately. Inspect thetank (1) and ensure that itsustained no damage duringshipment. Proper handling of thepolyethylene tank will ensurereliable performance. Do not dropthe tank or roll it on its side. Onlya non-marring sling should beused to lift the tank (see LiftingInstructions). Ensure that all liftingequipment is rated for the loadbeing lifted. Remove the tank lid(2) and verify that the supplycable cord grip (10) and thedischarge valve (4) are installed inthe tank. The inlet grommet (11)was shipped loose with the tank.The balance of the factory-

provided components wasdelivered with the grinder pumpunit. Inspect the shipping cartonsfor signs of any damagesustained during shipment. Openthe pump shipping carton(s) andverify that the grinder pump (6),pump stand (7), discharge hoseassembly (8), equalizer (13), andsupply cable (9) are enclosed.Open the alarm panel (12)shipping carton(s) and ensure thatalarm panel has sustained noshipping damage. If damage issuspected on any of thecomponents, do not proceed withinstallation. Notify an EnvironmentOne representative of any damagediscovered or any missingcomponents.

2. Site Excavation(Figure 2)

Excavate a hole of sufficientdepth and width to accommodatethe tank, ballast, undergroundpiping and required backfillmaterial as well as providingadequate working space for

plumbing and electricalconnections. The base of theexcavated hole should be leveland prepared with proper beddingmaterial, such as gravel, inaccordance with the siteengineer’s requirements. Thedepth of the excavation must besufficient to accommodate thebedding material and tank burial.The station burial depth dependson the specific 2010iP modelbeing installed. Figure 4 showsthe appropriate burial depth bymodel (cover style) for each. Thesize, shape and shoringrequirements of the excavationwill be based on the soilconditions and should be inaccordance with the siteengineer’s recommendation andsafety requirements.

3. Tank Installation

Improper handling of the tankmay result in damage and,ultimately, failure of the station.Care should be taken during liftingand placement to prevent

Fig. 2 - Excavation and Ballast

5 PA2105P01 Rev. B

Fig. 3 - Allowable Inlet Locations

impacting or otherwise damagingthe tank. A non-marring slingshould be used when lifting thetank (see Lifting Instructions).Ensure that the lifting sling israted for the load being lifted.Lifting chains or cables shouldnever be placed in direct contactwith the tank surfaces. Place thetank on the level bed of fillmaterial in the excavated hole.Orient the installed dischargefitting, as required, to align it withthe existing or proposeddischarge piping path.

4. Inlet Pipe Location

A 100 mm uPVC inlet grommetwas provided with the station forsealing the inlet pipe at the tankwall. Other inlet pipe grommetsizes are also available (Section7). The location of the tank inletmust be determined to supportfinal positioning of the tank priorto ballast installation. The inletpipe location corresponds with theactual or projected point wherethe 100 mm building sewer line

intersects the tank wall. Thegrade of the inlet pipe andrequired burial depth (per nationaland local code requirements)must be accounted for whendetermining the inlet location. Thesupply cable path (Figure 6 andSection 10) should be consideredwhen selecting the inlet location.A 127 mm diameter fieldpenetration of the tank wall isrequired to support installation ofthe 100 mm (standard) inletgrommet. This penetration mustnot remove or interfere with any ofthe structural ribbing on thepolyethylene tank. The inletgrommet may be installed in anyof the allowable locations shownin Figure 3. The inlet penetrationmust be centered in the locationselected to prevent interferencewith the tank ribbing. Typical inletinstallation will be on one of the200 mm diameter, raised panelson the tank body. The panels havebeen marked with a series oflocating lines to support centeringof the drilled penetration. Theselected elevation of the inlet

penetration must be incompliance with national andlocal code requirements. Any inletinstalled in the depressed panelsbetween the horizontal andvertical ribbing must be centeredwithin the panel to provideadequate clearance for the 152mm diameter flange on thestandard 100 mm inlet grommet(Figure 3). Do not install inlet inlower, tapered section of the tank.Once the location of the inletpenetration is selected, mark theinlet center location on the tankand position the tank to line upthe inlet location with the inletpipe path.

5. Ballast Installation

A concrete anchor is requiredto prevent flotation of thepolyethylene tank whengroundwater is present. Thevolume of concrete used mustcomply with the site engineer’srequirements. Recommendedminimum ballast volumes arepresented in Chart 1 of the Ballast

6PA2105P01 Rev. B

Calculation page. Ensure that thetank is properly positioned in theexcavation to accomodate themarked inlet location (Section 4)before pouring the concreteballast. Concrete ballast shouldbe cast in place around the tankin the excavation. Do not pourthe concrete ballast above themarked inlet pipe location. Ifthe ballast must be poured abovethis level, proceed with installationof the inlet piping (Section 7)before pouring the concrete. Theinlet pipe must be sleeved with a200 mm tube prior to pouring. Thetank should be filled with water, toa level above the specified ballastheight to prevent shifting duringthe concrete pour.

Alternatively, precast concrete,around the tank bottom, may beused for ballast (Figure 2). Do notpour ballast above the intendedinlet location. If this ballastmethod is used, lifting hooksmust be anchored in the concreteto support subsequent handling ofthe tank. The lifting hooks mustbe adequate to support the

combined weight of the tank andconcrete ballast, and should besized and installed in accordancewith the site engineer’srecommendation. Place theballasted tank in the excavatedhole using the lifting hooks. Donot lift by any of the tanksurfaces if precast ballast isutilized.

6. Venting(Figure 4)

The 2010iP station is a sewagehandling pump and requiresventilation for proper and safeoperation. The method of stationventilation will vary depending onthe specific model ordered. Thevent location for each model isshown in Figure 4. Do not burythe station above the appropriateburial line (by model) indicated inFigure 4. Burial above this levelwill result in blockage of theintegral cover vent systemprovided on most 2010iP models.

If the water level outside of thestation is expected to rise above

the surrounding grade (flooding), acover vent system cannot beused. If flood conditions areexpected, an underground (lateral)vent system and solid cover, asshown on the Model 2010iP 800mm x 1900 mm station, must beused. Refer to the E/One 2000iLateral Vent InstallationInstructions (PA2114P01) forinformation about undergroundstation venting. Consult thefactory if flood conditions arepossible where the station is tobe installed.

7. Inlet Installation(Figure 5)

The station is supplied with astandard grommet to accept a100 mm DWV uPVC (110.2 mmOD) sewer inlet pipe. Thegrommet is self-sealing and doesnot require the use of additionalsealant or adhesives. Verify thatthe grommet supplied with the2010iP station will accommodatethe selected inlet piping. Using a127.0 mm (5”) hole saw, drill

Fig. 4 - Tank Installation

7 PA2105P01 Rev. B

through the polyethylene tank wallat the marked inlet location(Section 4). Remove any burrs orchips from the drilled-hole edges.

Note: Other grommet sizes areavailable upon request. Alternategrommet sizes may require adifferent diameter tankpenetration. Consult an E/Onerepresentative before drilling thetank inlet if an alternate grommetis required.

Install the supplied inletgrommet in the drilled hole. Placea mark on the inlet pipe about 90mm from the end that will enterthe tank. A bevel should beground or filed on the pipe end toaid in installation through thegrommet (Figure 5). Clean thegrommet and pipe surfaces toremove any debris. Apply a filmof pipe soap or dish soap to theoutside surface of the inlet pipeend and the inside of thegrommet. Insert the beveled pipeend into the grommet and pushthe inlet pipe into the tank untilthe 90 mm mark lines up with thegrommet’s outside edge. Inspectthe grommet flange on the outsideof the tank. The flange should beflush against the tank wall andcompletely visible when the pipeand grommet are installedproperly.

8. Tank Discharge PipingConnection(Figure 6)

Connect the tank dischargepiping to the threaded tank fitting.The 1-1/4” BSP female thread onthe discharge fitting willaccommodate a variety of pipematerials and fittings. Dischargepiping must be selected inaccordance with local andnational plumbing codes. Ifallowable, the use of PE100, 40mm OD, PN16, SDR11polyethylene pipe isrecommended. If polyethylenedischarge piping is used,compression type fittings thatprovide a smooth inner passageshould be utilized. It isrecommended that an isolationvalve and a redundant check valveassembly (boundary kit) beinstalled between the pumpdischarge valve and the streetmain on all installations. Neveruse a ball type valve as a checkvalve. It is recommended that thevalves be installed as close to thepublic right-of-way (road reserve)as possible. Check local codesfor applicable requirements.

CAUTION: Redundant checkvalves on station laterals and anti-siphon/check valve assemblieson the grinder pump cores shouldnot be used as system isolationvalves during line tests.

9. Alarm Panel Mounting

Before proceeding, verify thatthe supply voltage is the same asthe motor voltage shown on thegrinder pump nameplate.Determine the location of thestation alarm panel. The alarmpanel may be mounted on a poleor directly on an outdoor wallsurface. The mounting locationselected must be visible from thegrinder pump station location andprovide general visibility to theoccupants of the building. Thepanel’s audible alarm should beeasily heard by the occupants ofthe building. An alarm device isrequired on every installation,there shall be no exceptions.Mount the alarm panel to a wallor pole, securing it by themounting flanges with fourscrews. Any penetrations into theEnvironment One alarm panelshall be undertaken in such a wayas to maintain the integrity of theIP rating (NEMA 4X, IP 65).

10. Electrical Connection

10a. Supply Panel to E/OneAlarm PanelWiring of supply panel andEnvironment One alarm panelshall be carried out per the wiringinstructions included with thespecific alarm panel provided, inaccordance with AS3000, and tothe satisfaction of relevantauthorities.

10b. Grinder Pump to AlarmPanel (Figure 6)

The Environment One 2010iPgrinder pump station is providedwith a cable for connectionbetween the station and the alarmpanel. This cable is referred to asthe “supply cable.” The supplycable is shipped coiled, inside thegrinder pump shipping carton. Thesupply cable (a six-conductor traycable) may, under conditionsoutlined in AS3000, be directlyburied. However, Environment Onerecommends the cable be locatedwithin a suitable, rigid, heavy-dutyconduit. Minimum depth of the

Fig. 5 - Inlet Installation

8PA2105P01 Rev. B

Fig. 6 - Typical Station Installation

cable shall be 500 mm. Thecable must be provided withadequate mechanical protectionand identification per AS3000. Thecable and protection must beinstalled with adequate allowancefor ground movement andexpansion. All conduit shall enterthe alarm panel from the bottomand shall be sealed to maintainthe integrity of the IP rating.NOTE: Wiring must be installedin compliance with AS3000.

10c. Installing E/One SupplyCable (Figure 7)

1) Open the lid of the stationand locate the supply cableconnector on the inside wall of thetank. Loosen the nut on theconnector and feed the free end(the end without the E/One EQDhousing) of the supply cablethrough the connector from theinside of the station. Pull the

supply cable out through theconnector until it hits the crimped“stop” feature on the cable,approximately 900 mm from theEQD housing.

**IMPORTANT: All but 900 mmof the cable must be pulled out ofthe station, and the cableadjacent to the EQD should besecured in position using theprovided hangers to ensure thatthe pump functions properly(Figure 7). Do not leave excesscable in the station.

2) Run the cable underground,in a trench or tunnel, in suitableconduit, per AS3000, to thelocation of the E/One panel. Usecare when installing and buryingthe supply cable. If the cable iscut or otherwise damaged it mayresult in a pump malfunction.Connections made at the panelare shown in the wiring diagramaccompanying the alarm panel.

3) Retighten the supply cable

connector nut. This connectionmust be tight or ground water willenter the station.

11. Tank Backfill

Proper backfill is essential tothe long-term reliability of the2010iP grinder pump station. Thechoice of backfill material isdependent upon the local soil andgroundwater conditions and mustbe in accordance with the siteengineer’s requirements. Therecommended method ofbackfilling is to surround the unitto the burial level (Figure 4) withproper fill. The backfill materialshall be to the satisfaction of thelocal relevant authority. Backfillshall be free of organic andcompressible material and shallbe free of voids and cavities.Compaction moisture contentshall generally be 1% dry and 2%wet of the optimum content.

9 PA2105P01 Rev. B

Backfill shall be compacted to theminimum standard dry densityratios, AS1289, 95%. Clays andsilts (12% or more passingthrough #200 (.075 mm) sieve) arenot suitable backfill for this or anyunderground structure such asinlet or discharge lines. If you areunsure of the consistency of thenative soil, it is recommendedthat a geotechnical evaluation ofthe material be obtained beforespecifying backfill. Another optionis the use of a flowable fill (i.e.,low slump concrete). This isparticularly attractive wheninstalling grinder pump stations inaugured holes where tightclearances make it difficult toensure proper backfilling andcompaction with dry materials.Flowable fills should not bedropped with more than 1-1/4meters between the dischargenozzle and the bottom of the holebecause this can causeseparation of the constituentmaterials.

12. Grinder Pump StandAssembly (Figure 8)

Temporarily rest the grinderpump on its side. Using a block ofwood or similar object, prop upthe lower pump end to allowinstallation of the pump stand.Align the two legs of each pumpstand half with two of the holes inthe pump lower end. Push thestand legs into the pump lowerend until the bend in each stand

leg bottoms against the pump-housing surface. Turn the pumpupright on the installed stand.Install one stand retaining ring oneach of the four leg endsprotruding through the pump lowerend. The retaining rings are apressure fit and are easily tappedin place using a 8 mm socket ornut driver and mallet. Theretaining rings should only bedriven onto each legapproximately 6 mm. Do notattempt to bottom the ringsagainst the angled pump surfaceas this may distort the ring andlessen its holding power.

13. Pump Installation(Figure 9)

The grinder pump shouldonly be installed in the stationupon connection and

commissioning of thedischarge piping, connectionof the inlet piping to thebuilding sewer, and uponavailability of pump stationpower from the providedalarm panel to support start-uptesting (see Section 14).

Prior to installing the grinderpump in the tank, flush the inletpipe with water to force anymiscellaneous debris in the sewerline into the tank. Heavy debris,sand, clay, constructionmaterials, etc. should be removedfrom the tank before installing thegrinder pump. The grinder pumpwas supplied with all of thenecessary plumbing componentsto connect the pump discharge tothe tank discharge valve.

1. Ensure that one slip nut andone split ring are properlylocated behind the raisedbead on each end of thedischarge hose.

2. Place one back-up ring andone O-ring on each end of thedischarge hose assemblybetween the raised bead andthe edge of the hoseassembly. Note that themolded groove in the back-upring is designed to be placedadjacent to the rubber O-ring.

3. Slide the straight, stainlesssteel end of the dischargehose assembly into the top ofthe check valve assembly onthe grinder pump until theraised bead contacts thecheck valve housing. Both the

Fig. 7 - Electrical Cables

Fig. 8 - Pump Stand Installation

10PA2105P01 Rev. B

O-ring and back-up ringshould slide into the bore ofthe check valve housing. Thehose should be oriented asshown in Figure 9 to supportalignment with the stationdischarge valve.

4. Secure the hose assembly tothe pump by tightening theslip nut onto the check valvehousing. Overtightening theslip nut may damage thecheck valve. The slip nutshould only be tightened to ¼to ½ turn beyond hand-tight.

5. Using the pump liftingharness, lower the grinderpump into the tank until thepump stand rests on thebottom surface of the tank.Orient the pump in the basinso that the curved end of thedischarge hose is alignedwith the discharge valvereceiver.

6. Slide the curved, stainlesssteel end of the dischargehose assembly into thedischarge valve receiver untilthe raised bead contacts thetop of the valve receiver. Boththe O-ring and back-up ringshould slide into the bore ofthe valve receiver.

7. Secure the hose assembly tothe discharge valve bytightening the slip nut ontothe valve receiver. The slip nutshould only be tightened to ¼to ½ turn beyond hand-tight.

8. The valve handle should beleft in the “OFF” (horizontal)position until system start-uptesting is conducted.

After completing the plumbing,proceed with connecting thepump power cable. The grinderpump power cable is suppliedwith the mating half of the EQDconnector. Verify that the EQD O-rings are in place on the grinderpump power cord (Figure 7). Plugthe pump power cable into thesupply cable EQD connector.Note that the EQD halves are“keyed” and the plug connectionscan only be made one way.Secure the EQD connection bytightening the locking ring until itstops. Using the provided hanging

hooks, secure the EQD andsupply cable at the top of the tank(Figure 7).

14. Start-Up Procedure

When the system is completelyinstalled, the station should bechecked to ensure properinstallation and reliableperformance.

SYSTEM INSPECTION

Perform the followinginspections:

• Proper burial depth – the tankshould have been buried tothe burial level shown (Figure4).

• Proper grading – thesurrounding soil should begraded down, away from thestation.

• Station supply cable – thestation supply cable must notbe exposed outside of thestation. Suitable conduit, perAS3000, should be used.Proper burial depth (500 mm)

shall be maintained.• Alarm panel – ensure that the

alarm panel is properlymounted and free of anydamage. Verify that the alarmpanel has been wired properlyin accordance with the wiringinstructions provided with thepanel.

ELECTRICAL TESTS

The following electrical tests arerecommended prior to operatingthe grinder pump station. Thesetests require the use ofappropriate electrical testequipment and should only beperformed by qualified personneltrained in the safe operation ofthis equipment and electricalsystem servicing.

• The pump should stop withinapproximately an additional 2minutes.

OPERATIONALELECTRICAL TEST

The following electrical test isrecommended in conjunction withthe Start-Up Test of the grinderpump station. This test requiresthe use of appropriate electricaltest equipment and should onlybe performed by qualifiedpersonnel trained in the safeoperation of this equipment andelectrical system servicing.

1. The current to the grinderpump should be measured inthe alarm panel, at the blackwire supplying the pumpstation (supply cable).

2. Using an ammeter, measurethe current in the black wirewhile the pump is operating.

3. The current should bebetween 5 amps and 6.7amps.

4. Higher amperage indicateshigher discharge pressure.Measured current in excessof 6.7 amps could indicate ablocked or closed dischargeline. Correct any blockageproblems and confirm that thecurrent is within theacceptable range. If thecurrent remains outside ofthe acceptable range, andno discharge blockage isdetected, contact yourlocal Environment One orqualified servicerepresentative.

3. Perform Continuity Testprocedure in accordance withthe Environment One 2000iGrinder Pump ServiceManual.

4. Turn “ON” the power to thealarm panel from the buildingservice panel.

5. Using a test (volt) meter,verify that the incoming panelvoltage is within 10% of thepump nameplate voltage (for240V pump, voltage at panelmust be 216V to 264V). Ifthe voltage is outside ofthis range, do not continuewith station start-up. Thevoltage problem must becorrected prior toproceeding.

START-UP TEST

The following test must beperformed prior to placing thesystem in service:

1. Ensure all service and alarmpanel breakers are in the“OFF” position.

2. Open the discharge valve inthe tank by swinging the valvehandle to the “ON” (vertical)position.

3. Open any additionaldischarge lines. Someinstallations may haveadditional discharge linevalves before entering thestreet main.

4. Turn “ON” power to the alarmpanel, from the buildingservice panel.

5. Set the alarm circuit breakerin the alarm panel to the “ON”position.

6. Fill the polyethylene tank withwater until the red alarm lighton the alarm panel is lit andthe alarm buzzer sounds.Shut off the fill water.

7. Set the grinder pump circuitbreaker in the alarm panel tothe “ON” position. Oncepower is turned on to thegrinder pump:

• The grinder pump shouldstart immediately.

• The red alarm lamp andbuzzer should switch off inapproximately 3 minutes.

Lifting Instructions

2. No Ballast, (to be poured in place):

If the concrete anchor is to bepoured while the station is inplace lift the unit using 2 nylonstraps wrapped around the tankexterior just below the coverflange, as shown below. Keepstation oriented vertically to avoidany damage.

3. Precast Ballast:Never lift a station that has

ballast attached by any meansexcept the lifting hooks. Theweight of the concrete willdamage the station if you attemptto lift it from any part of thestation.

1. Transporting unit to installation site:

If the station has been shippedsecured to a pallet, lift the unitfrom the bottom duringtransportation. Alternatively, liftthe unit using 2 nylon strapswrapped around the tank exterior,just below the cover flange asshown below. Never roll astation or move it on its side.

FAILURE TO FOLLOW THESE INSTRUCTIONS COMPLETELY WILL VOID WARRANTY.

13 PA2105P01 Rev. B

A ballast, or concrete anchor, of proper volume and weight is required on most in-ground installations. Thefollowing section explains how to arrive at the correct size ballast. The amount of ballast needed is equal tothe weight it would take to counterbalance the buoyant force exerted on a fully submerged station.

Installation Site Assumptions1. Water table – under worst case, the ground water level is assumed to be at the finished grade level.

2. Backfill materials per E/One Installation Instructions (Model 2010iP).

3. The consulting engineer should perform a soil test to determine if the assumptions that have beenmade are valid for the specific installation site. If the site conditions differ from these assumptions, then theconsulting engineer may revise the calculations as shown in this document.

Physical Constants1. Density of Water = 1000 kg/m3

2. Density of Concrete (in air)= 2402 kg/m3

3. Density of Concrete (in water)= 1402 kg/m3

4. Density of Saturated Backfill = 1120 kg/m3

ProcedureA. Determine The Buoyant Force Exerted On The Station

1. Determine the buoyant force that acts on the grinder pump station when it is submerged in water. 2. Subtract the weight of the tank from the buoyant force due to the submerged tank to determine the net buoyant force acting on the station.

B. Determine The Ballast Force Exerted On The Station

1. Determine the ballast force applied to the station from the concrete and saturated soil sur- rounding the station.

C. Subtract The Ballast Force From the Buoyant Force.

1. Note – if the installation site conditions are different from those listed above, the consulting engineer should recalculate the concrete ballast.

Ballast CalculationsThe following calculations are to outline the areas used to determine the volumes of the different

materials for the ballast. All sections referred to in the calculations are marked on the accompanyingdrawing.

E/One Series 2010iP Grinder Pump StationBallast Calculations

Sample Calculation GP 2010iP, 800mm x 2100mm Station

Volume of Station = .79 m3

Tank Weight = 75 kgStation Height = 2.02 m

A. Buoyant Force1. The buoyant force acting on the submerged GP 2010iP is equal to the weight of the displaced water

for the section of the tank that is submerged. Fbuoyant = (density of water)(volume of station)

= (1000 kg/m3)(.79 m3)= 790 kg

2. The net buoyant force acting on the station (Fnet-buoyant) is equal to the buoyant force (Fbuoyant) minus theweight of the station tank.

Fnet-buoyant = 790 kg - 75 kg= 715 kg

B. Ballast Force 1. Determine the volume of concrete & soil

Section I: Used To Determine The Volume Of Concrete (Note: .691m = assumed, inside diameter of concrete ballast ring around tank bottom flange)

Volume = (Height)(Area)= (.178 m)(πππππ)((1.066 m)2 - (.691m)2)/4= (.178 m )(.517 m2)= .092 m3

Section II: Used To Determine The Volume Of Saturated Soil (Note: .815 m = assumed, inside diameter of soil column around tank maximum diameter)

Volume = (Height)(Area)= (2.02 m - .178 m)(πππππ)((1.066 m)2 - (.815 m)2)/4= (1.842 m)(.371 m2)= .683 m3

2. Determine the combined ballast

Ballast (total) = Ballast (concrete) + Ballast (saturated soil)= (Vconcrete)(density concrete in water) + (Vsoil)(density saturated soil)= (.092 m3)(1402 kg/m3) + (.683 m3)(1120 kg/m3)= 128 kg + 765 kg= 892 kg

C. Subtract the net buoyant force from the ballast force to determine the final conditionFinal Condition = Ballast Force - Net Buoyant Force

= 892 kg - 715 kg= 177 kg (excess ballast)
