SafetyPrecautions
- �� -
• Donotusetheexistingrefrigerantpiping.- The old refrigerant and refrigerant oil in the existing
p�p�ng conta�ns a large amount of chlor�ne wh�ch may cause the refrigerant oil of the new unit to dete-riorate.
- R410A is a high-pressure refrigerant and can cause the existing piping to burst.
• UserefrigerantpipingmadeofC1220(CU-DHP)phosphorusdeoxidizedcopperasspecifiedintheJISH3300“Copperandcopperalloyseamlesspipesandtubes”.Inaddition,besurethatthein-nerandoutersurfacesofthepipesarecleanandfreeofhazardoussulphur,oxides,dust/dirt,shav-ingparticles,oils,moisture,oranyothercontami-nant.
- Contaminants on the inside of the refrigerant piping may cause the refrigerant residual oil to deteriorate.
• Storethepipingtobeusedduringinstallationindoorsandkeepbothendsofthepipingsealeduntiljustbeforebrazing.(Storeelbowsandotherjointsinaplasticbag.)
- If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and compressor trouble may result.
• Applyasmallamountofesteroil,etheroil,oralkylbenzenetoflares.(forindoorunit)
- Infiltration of a large amount of mineral oil may cause the refrigerant oil to deteriorate.
• Useliquidrefrigeranttofillthesystem.- If gas refrigerant is used to seal the system, the
composition of the refrigerant in the cylinder will change and performance may drop.
• DonotusearefrigerantotherthanR410A.- If another refrigerant (R22, etc.) is mixed with
R410A, the chlor�ne �n the refr�gerant may cause the refrigerant oil to deteriorate.
• Useavacuumpumpwithareverseflowcheckvalve.
- The vacuum pump oil may flow back into the refrig-erant cycle and cause the refrigerant oil to deterio-rate.
• Donotusethefollowingtoolsthatareusedwithconventionalrefrigerants.
(Gaugemanifold,chargehose,gasleakdetector,reverseflowcheckvalve,refrigerantchargebase,refrigerantrecoveryequipment)
- If the conventional refrigerant and refrigerant oil are mixed in the R410A, the refrigerant may deterio-rated.
- If water is mixed in the R410A, the refrigerant oil may deteriorate.
- Since R410A does not contain any chlorine, gas leak detectors for conventional refrigerants will not react to it.
• Donotuseachargingcylinder.- Using a charging cylinder may cause the refrigerant
to deteriorate.• Donotuseantioxidantorleak-detectionadditive.• Beespeciallycarefulwhenmanagingthetools.- If dust, dirt, or water gets in the refrigerant cycle, the
refrigerant may deteriorate.
• Iftheairconditionerisinstalledinasmallroom,measuresmustbetakentopreventtherefriger-antconcentrationfromexceedingthesafetylimiteveniftherefrigerantshouldleak.
- Consult the dealer regarding the appropriate meas-ures to prevent the safety limit from being exceeded. Should the refrigerant leak and cause the safety limit to be exceeded, hazards due to lack of oxygen in the room could result.
• Whenmovingandreinstallingtheairconditioner,consultthedealeroranauthorizedtechnician.
- If the air conditioner is installed improperly, water leakage, electric shock, or fire may result.
• Aftercompletinginstallationwork,makesurethatrefrigerantgasisnotleaking.
- If the refrigerant gas leaks and is exposed to a fan heater, stove, oven, or other heat source, �t may gen-erate noxious gases.
• Donotreconstructorchangethesettingsoftheprotectiondevices.
- If the pressure sw�tch, thermal sw�tch, or other protection device is shorted and operated forcibly, or parts other than those specified by Mitsubishi Electric are used, fire or explosion may result.
• Todisposeofthisproduct,consultyourdealer.• Theinstallerandsystemspecialistshallsecure

ments.- Oil, steam, sulfuric smoke, etc. can significantly reduce
the performance of the air conditioner or damage its parts.
• Wheninstallingtheunitinahospital,communica-tionstation,orsimilarplace,providesufficientprotectionagainstnoise.
- The inverter equipment, private power generator, high-frequency medical equipment, or radio commu-nication equipment may cause the air conditioner to operate erroneously, or fail to operate. On the other hand, the air conditioner may affect such equipment by creating noise that disturbs medical treatment or image broadcasting.
• Donotinstalltheunitonastructurethatmaycauseleakage.
- When the room humidity exceeds 80 % or when the drain pipe is clogged, condensation may drip from the indoor unit. Perform collective drainage work together with the unit, as required.
- �v -
• Groundtheunit.- Do not connect the ground wire to gas or water
pipes, lightning rods, or telephone ground lines. Improper grounding may result in electric shock.
• Installthepowercablesothattensionisnotappliedtothecable.
- Tension may cause the cable to break and generate heat and cause a fire.
• Installaleakcircuitbreaker,asrequired.- If a leak circuit breaker is not installed, electric shock
may result.• Usepowerlinecablesofsufficientcurrent
carryingcapacityandrating.- Cables that are too small may leak, generate heat,
and cause a fire.• Useonlyacircuitbreakerandfuseofthe
specifiedcapacity.- A fuse or c�rcu�t breaker of a larger capac�ty or a
steel or copper w�re may result �n a general un�t failure or fire.
• Donotwashtheairconditionerunits.- Washing them may cause an electric shock.• Becarefulthattheinstallationbaseisnot
damagedbylonguse.- If the damage is left uncorrected, the unit may fall
and cause personal injury or damage property.• Installthedrainpipingaccordingtothismanualto
ensureproperdrainage.Wrapthermalinsulationaroundthepipestopreventcondensation.
- Improper drain piping may cause water leakage and damage to furniture and other possessions.
• Beverycarefulaboutproducttransportation.- If the un�t we�ghs more than 20kg, carry the un�t w�th
more than one person.- Some products use PP bands for packaging. Do not
use any PP bands for a means of transportation. It is dangerous.
- When transporting the unit, support it at the specified positions on the unit base. Also support the unit at four points so that it cannot slip side ways.
• Safelydisposeofthepackingmaterials.- Packing materials, such as nails and other metal or
wooden parts, may cause stabs or other injuries.- Tear apart and throw away plastic packaging bags
so that it is out of reach of children. If children play w�th a plast�c bag wh�ch was not torn apart, they face the risk of suffocation.
- v -
• Turnonthepoweratleast12hoursbeforestartingoperation.
- Starting operation immediately after turning on the main power switch can result in severe damage to internal parts. Keep the power switch turned on during the operational season.
• Donottouchtheswitcheswithwetfingers.- Touching a switch with wet fingers can cause elec-
tric shock.• Donottouchtherefrigerantpipesduringandim-
mediatelyafteroperation.- During and immediately after operation, the
refrigerant pipes are may be hot and may be cold, depending on the condition of the refrigerant flowing through the refrigerant piping, compressor, and other refrigerant cycle parts. Your hands may suffer burns or frostbite if you touch the refrigerant pipes.
• Donotoperatetheairconditionerwiththepanelsandguardsremoved.
- Rotat�ng, hot, or h�gh-voltage parts can cause injuries.

(4) Connecting refrigerant pipes and drain pipes
(4)-1 Refr�gerant p�p�ng workThis piping work must be done in accordance with the installation manuals for outdoor unit (heat source unit).• For constraints on pipe length and allowable difference of elevation, refer to the outdoor unit installation manual.• The method of pipe connection is brazing connection.
Caution:• Installtherefrigerantpipingfortheindoorunitinaccordancewiththefollowing.1. Cut the tip of the indoor unit piping, remove the gas, and then remove the brazed cap. [Fig. IV. 2. (4). 1]
2. Pull out the thermal insulation on the site refrigerant piping, braze the unit piping, and replace the insulation in its original position.
Wrap the piping with insulating tape.Note:• Paystrictattentionwhenwrappingthecopperpipingsincewrappingthepipingmaycausecondensation
insteadofpreventingit.* Before brazing the refrigerant piping, alwayswrapthepipingonthemainbody,andthethermalinsulation

• Provideametalbracetosupporttherefrigerantpipesothatnoloadisimpartedtotheindoorunitendpipe.Thismetalbraceshouldbeprovided500mmawayfromtheindoorunit’sflareconnection.
Warning:Wheninstallingandmovingtheunit,donotchargeitwithrefrigerantotherthantherefrigerant(R407CorR22)specifiedontheunit.- Mixing of a different refrigerant, air, etc. may cause the refrigerant cycle to malfunction and result in severe damage.
Caution:• UserefrigerantpipingmadeofC1220(CU-DHP)phosphorusdeoxidizedcopperasspecifiedintheJISH3300
“Copperandcopperalloyseamlesspipesandtubes”.Inaddition,besurethattheinnerandoutersurfacesofthepipesarecleanandfreeofhazardoussulphur,oxides,dust/dirt,shavingparticles,oils,moisture,oranyothercontaminant.
• Neveruseexistingrefrigerantpiping.- The large amount of chlorine in conventional refrigerant and refrigerator oil in the existing piping will cause the new
refrigerant to deteriorate.• Storethepipingtobeusedduringinstallationindoorsandkeepbothendsofthepipingsealeduntiljust
beforebrazing.- If dust, dirt, or water gets into the refrigerant cycle, the oil will deteriorate and the compressor may fail.
(4)-4 Dra�n p�p�ng work
1. Ensure that the drain piping is downward (pitch of more than 1/100) to the outdoor (discharge) side. Do not provide any trap or irregularity on the way. (a)
2. Ensure that any cross-wise drain piping is less than 20 m (excluding the difference of elevation). If the drain piping is long, provide metal braces to prevent it from waving. Never provide any air vent pipe. Otherwise drain may be ejected.
3. Use a hard vinyl chloride pipe VP-25 (with an external diameter of 32 mm) for drain piping.4. Ensure that collected pipes are 100 mm lower than the unit body’s drain port as shown in (b). 5. Do not provide any odor trap at the drain discharge port.6. Put the end of the drain piping in a position where no odor is generated.7. Do not put the end of the drain piping in any drain where ionic gases are generated. [Fig. IV. 2. (4).3]

(1)-1 Caut�on for water p�pe �nstallat�onConsider the following when designing and installing a water piping system.• Do not use steel pipes as water pipes.- Copper pipes or stainless steel pipes are recommended.If iron pipes are used in the existing system, do not connect
a new circuit to the old one. Keep the existing and new circuits separate. • Light pipes are similar to other air-conditioning pipes, however, please observe the following precautions during installation.• Before a long period of non use, purge the water out of the pipes and thoroughly let them dry. • Use a closed water circuit. • When operating the unit, add brine to the circulating water to prevent it from freezing. To use brine in the system,
DipSW 1-10 must be set to ON.• When installed in a low-ambient temperature environment, keep the water circulating at all times. If that is not
possible, purge the water out of the pipes completely. • Do not use the water used for this unit for drinking or food manufacturing.• When the ambient temperature is 0 ˚C or lower during stop operation, keep the water circulating at all times, or
purge the water out of the pipes completely.

joints are installed.PT 1 Screw*1 PT 1 Screw*1
(2) Select�ng a water pumpUse a pump that is large enough to compensate for the total water pressure loss and to supply sufficient water to the unit.
(3) Install�ng the stra�ner• Install the strainer at the angle of 45˚ or less as shown in [Fig. IV 3.(3).1].• Install the supplied strainer at the water inlet.
(4) Precautions during installation• Use the reverse-return method to insure proper pipe resistance to each unit.• To insure easy maintenance, inspection, and replacement of the unit, use a proper joint, valve, etc. on the water
intake and outlet port. In addition, be sure to install a strainer on the water intake pipe. (In order to maintain the heat source unit, a strainer on the circulating water inlet is necessary.)
* An example of the heat source unit installation is shown in [Fig. IV 3.(5).1].• Install a suitable air vent on the water pipe. After sending water through the pipe, be sure to vent the excess air.• Compressed water may form in the low-temperature sections of heat source unit. Use a drainage pipe connected to
the drain valve at the base of the unit to drain the water.• Install a back flow-prevention valve on the pump and a flexible joint to prevent excess vibration.• Use a sleeve to protect the pipes where they go through a wall.• Use metal fittings to secure the pipes, and install them so that they have maximum protection against breakage and
bending.• Do not confuse the water intake and outlet valves.• This unit doesn’t have any heater to prevent freezing within tubes. When the water flow is stopped on low ambient,
take out the water from tubes.• The unused knockout holes should be closed and the opening of refrigerant pipes, water pipes, power source and
transmission wires should be filled with putty and so on to prevent from rain. (field construction)• Wrap some sealing tape around the screw part to prevent water leakage. • Wrap the sealing tape as follows. 1. Wrap the joint with sealing tape in the direction of the threads (clockwise), and do not let the tape run over the edge. 2. Overlap the sealing tape by two-thirds to three-fourths of its width on each turn. Press the tape with your fingers so that it is pressed firmly against each thread. 3. Leave the 1.5th through 2nd farthest threads away from the pipe and unwrapped.• Hold the pipe on the unit side in place with a spanner when installing the pipes or strainer. Tighten screws to a torque
of 50 N.m. • Water pipes can get very hot, depending on the preset temperature. Wrap the water pipes with insulating materials
to prevent burns. • Install the expansion joint (accessory) at the inlet after installing the strainer, and outlet.

(7) Flow sw�tch �nstallat�on<Caution>When installing the unit, be sure to install the supplied flow switch on the water outlet side of the unit and connect the wire to IN1 of TB142A on the unit.If the flow switch is not installed, the unit will emit the error signal (2100: Interlock error) and not operate.* A short-circuit wire is supplied, but it is only for test run.
- 30 -
<Installation procedures>1) Remove the pipes attached to the flow switch.
Note: The unit is shipped with the pipes loosely tightened. 2) Wrap seal tape around the threads at the end of the pipes, starting at the 1.5th or 2nd thread, and not over the
openings. Apply two to three wraps in the direction of the pipe threads (clockwise). Each course of the tape should overlap the one before it by 2/3 to 3/4 the width of the tape. Run your fingers around the threads and tape to press the tape into the threads. Then, attach the pipes to the flow switch, holding parts A and B with a spanner. The maximum tightening torque is 60 N•m (611 kgf•cm).
3) Attach the flow switch and pipes to the water outlet in the horizontal position. The angle of the axis of the pipe should be less than 45 degrees. Check the direction of the flow switch as shown in Fig. C.
4) Connect the flow switch wire to IN1 of TB142A. From the External Wiring Input, route the wire as shown in Fig. D and connect it to the terminal as shown in Fig. E. Use a wire protector such as a rubber bushing in the access hole on the unit.

(8) Water processing and water quality controlTo preserve water quality, use the closed type of cooling tower for unit. When the circulating water quality is poor, the water heat exchanger can develop scales, leading to a reduction in heat-exchange power and possible corrosion of the heat exchanger. Please pay careful attention to water processing and water quality control when installing the water circulation system.• Removal of foreign objects or impurities within the pipes. During installation, be careful that foreign objects, such as welding fragments, sealant particles, or rust, do not enter
the pipes.• Water Qual�ty Process�ng
a) Depending on the quality of the cold-temperature water used in the air-conditioner, the copper piping of the heat exchanger may become corroded. We recommend regular water quality processing.Cold water circulation systems using open heat storage tanks are particularly prone to corrosion.When using an open-type heat storage tank, install a water-to-water heat exchanger, and use a closed-loop circuit on the air conditioner side. If a water supply tank is installed, keep contact with air to a minimum, and keep the level of dissolved oxygen in the water no higher than 1mg/liter.
b) Water quality standard
Reference : Guideline of Water Quality for Refrigeration and Air Conditioning Equipment. (JRA GL02E-1994)c) Please consult with a water quality control specialist about water quality control methods and water quality
calculations before using anti-corrosive solutions for water quality management.
d) When replacing a previously installed air conditioning device (even when only the heat exchanger is being replaced), first conduct a water quality analysis and check for possible corrosion.
Corrosion can occur in cold-water systems even if there has been no prior signs of corrosion.
If the water quality level has dropped, please adjust water quality sufficiently before replacing the unit. Refer to the below graph for the maximum amount of circulating water in the water pipe. Make sure that this amount does not exceed.
