The Questions
#1QuickTips
The purpose of the external equaliz-er is to sense the pressure in thesuction line AT THE BULBLOCATION and transmit it to theTEV diaphragm.
This usually means installing theexternal equalizer immediately down stream from the bulb. Thisensures the correct pressure is signaled to the TEV.
In some situations this “ideal” location may not be possible.In these cases, an alternate location, such as at B or C

(see diagram), could be used. However, the pressure at these loca-tions must be nearly identical to the pressure in the line where thebulb is located.
In other words, locations B and C are acceptable as long as thesepressures are essentially the same as A when the system is operat-ing at full load.
In the past there has been concern about installing the externalequalizer “up-stream” from the bulb. This was due to the possibil-ity of refrigerant leaking past the TEV push rods, passing throughthe equalizer line and into the suction line, thus falsely influencingthe TEV bulb temperature. Today, with Sporlan’s TEV design, thispossibility is virtually eliminated.

What makesthe Sporlan
Catch-All®
different?
The famous molded porous core.The Sporlan Catch-All Filter-Driereliminates all the weaknesses ofloose-filled models by molding ablend of specially selected des-iccants into a porous core. Thecore provides excellent filtrationwithout the problem of desiccantpowdering, packing and escapinginto the system, a common problemwith many loose fill driers.
#2QuickTips
What are thefunctions of
the Catch-All’sspecial blend of
desiccants?
Moisture Removal - Moisture is an importantfactor in the formation of acids, sludge, copperplating and corrosion.
Dirt Removal - Numerous metallic contami-nants such as cast iron dust, rust, steel and cop-per chips can damage compressor bearings andplug capillary tubes or expansion valves.
Sludge and Varnish Removal - Although theutmost precaution may be taken in the designand fabrication of a system, once in operation,unusually high discharge temperatures will causethe oil to break down and form sludge andvarnish.
Acid Removal - Acid-forming chemical reac-tions can occur under certain conditions. As anexample, at elevated temperatures, many refrig-erants will react with oil to form acids. This isparticularly true when moisture is present.
#3QuickTips
For indicating themoisturecontent, the See•Alls loca-tion can be anywhere in theliquid line. Because the levelof moisture contained in therefrigerant reaches “equilib-rium” soon after the installa-tion of the Catch-All, andshould remain at that levelunless moisture is introducedfrom some external source,the See•All correctly mea-sures the proper moistureconcentration at any point inthe liquid line.
The Sporlan See•All is a combina-tion moisture and liquid indicator.Therefore, it serves two functionswhen installed in the liquid line.

Satisfactory Location
#3QuickTips
From the standpointof indicating thecondition of therefrigerant (100%liquid or mixtureof liquid and bubbles)the preferred loca-tion is immediatelybefore the TEV.
One of the require-ments for properTEV operation, is asolid stream of liquid
refrigerant entering the valve. Positioning the See-All immediately before the TEV helps to ensurethat is the case. A clear sight glass is also an indi-cation of a properly charged system.
By locating the See-All downstream of the Catch-All, it can signal a restriction in the Catch-Allshould one occur. However, be careful not to con-fuse this with a shortage of refrigerant.

��
Locate the bulb on a straight, hori-zontal line, pitched slightly down,immediately after it leaves theevaporator.
A short trap should follow before thevertical line rises to be connected tothe compressor suction. With theline pitched down, any liquid refrig-erant and/or oil will pass into thetrap, away from the bulb. As thetrap fills with oil, the velocity of therefrigerant will carry the trapped oilinto the vertical section and bereturned to the compressor.
In general, the TEV bulb should beinstalled on a straight section ofhorizontal suction line.

#4QuickTips
Observing the same principles outlined above, the piping should bearranged to prevent the accumulation of oil and/or refrigerant atthe bulb location. Also, traps installed in the suction lines of evapo-rators B and C prevent the refrigerant from one evaporator fromentering the suction line of another evaporator.
�
In this piping configura-tion, no trap is requiredafter the bulb location,but the line should bepitched slightly down toprevent any liquid refrig-erant or oil from beingtrapped at the bulb location.

#5QuickTips
Except for very small sizes, most directexpansion evaporators used in refrig-eration and air conditioning systemsuse two or more circuits. In order forthe evaporator to perform at its maxi-mum capacity, equal refrigerant feedto each circuit is a necessity. In addi-tion, each circuit must be exposed toidentical heat loads.
Distributing equal amounts of liquid to each circuit is important inrefrigeration evaporators because the refrigerant leaving the TEV is amixture of liquid and vapor. There is a natural tendency for theliquid and vapor to separate, resulting in unequal amounts of liquidbeing fed to the various circuits. It is the liquid refrigerant flow intothe evaporator that produces nearly all the refrigeration effect. Thevapor contributes very little.
To ensure equal refrigerant feed, it is important to size the distribu-tor nozzle and tubes to match the system capacity as close as possi-ble. By doing this, the proper velocities are created to completelymix the liquid and vapor.

#5QuickTips
In addition to feeding equal amounts of liquid and vapor into eachcircuit to utilize the full capacity of the evaporator, each circuitmust be equally loaded. Figure A is a schematic illustration oftypical temperature conditions in the evaporator when both equaldistribution and equal loading occur.
Figure B illustrates the same evaporator but with the air flow(and thus the load) less over circuit #3. The load imbalance will beindicated by low superheat at the outlet of circuit #3, and high super-heat at the outlet of circuits #1 and #2. Other symptoms are lowerthan normal suction pressure, reduced evaporator capacity and TEVhunting with possible flood-back.
When planning a system refrigerant conversion it is critical to con-sider nozzle and tube sizing.
For complete sizing and application information refer to SporlanBulletin 20-10.

#6QuickTips
It is not uncommon to see refrigera-tion and air conditioning systems thathave operated for decades, without anyservice being performed, and with theCatch-All undisturbed since the origi-nal installation. This speaks well, notonly for the reliability and durabilityof all the system operating compo-
nents, but also for the Catch-All which has provided protection tothese components over the many years of operation.
At the initial start-up the Catch-All removed any dirt or excessivemoisture that may have been in the system. During the years ofoperation, the Catch-All continued to provide protection by insuringthat no acid or contaminants formed during periods of high con-densing or discharge temperatures.
Unfortunately, things do not always go this smoothly and servicecalls are necessary. This is when consideration should be given tochanging the filter-drier.
Here are some questions that will help determine whether to changethe Catch-All:
1. Did the See•All indicate moisture was present?
2. Was the system open during service?
3. Were there any unusual circumstances that couldhave permitted moisture to enter the system?(ruptured chiller or water cooled condenser; wetconditions in area where repairs are taking place)
4. Was there a hermetic motor burn-out involved?
5. Was excessive compressor heat involved in the failure?
6. Is the refrigerant oil discolored or found to beacidic? (A Sporlan Acid Test Kit will determine this)
7. Was it evident that dirt, metal chips or othercontaminants were involved in causing the failure?
When should aCatch-All®

Replaceable Core Catch-All
Compact Style SuctionLine Catch-All
If the answer to any of these is “yes”, a new Catch-All is good insur-ance against a repeat problem. If questions 3, 4 or 5 are answered“yes”, both a suction line and liquid line Catch-All are recom-mended to remove acids and products of oil decomposition. SporlanBulletin 40-10 outlines the procedure for this type of cleanup.
The Sporlan See•All and Acid Test Kits are excellent service tools fordetermining if a replacement of the Catch-All or other filter-drier isrequired.

The O valve uses a forced balanced pis-ton to reduce the impact of varyingcondensing or valve inlet pressure onthe valve's superheat control setting.The piston (pin) in a conventional TEVdesign is exposed to high inlet pressureon the top and low outlet pressure onthe bottom. The pressure imbalanceacross the pin acts as an opening forcethat will vary the superheat control set-ting of the valve by increasing the loadon the superheat adjustment spring. Aspressure differential across a conven-tional TEV pin increases, typicallycaused by increasing condensing

Split-Condensers are used in largerefrigeration systems to assist in headpressure control and to minimize theamount of system refrigerant chargerequired.
The size of the condenser required forsummer operation is split into two par-
allel circuits. One circuit (designated “summer/winter”) is activein summer and winter. The other circuit (designated “summer con-denser”) is rendered inactive during winter operation by a 3-WaySplit Condenser Valve.
As the piping diagram indicates, a check valve is installed in theoutlet of each condenser circuit, and head pressure controls areused to maintain minimum and stable head pressures. The twocondensers are usually split 50/50 in size and are contained in thesame “tube bundle” using condenser fan control as a supplementto the head pressure control valves. With this combination, therequired refrigerant charge is kept to an absolute minimum.

There has always been a tendency toselect solenoid valves on the basis of linesize. This is very risky.
While a 5/8” line size and a 5/8” ODFsweat connection sound like a perfectmatch, other factors must be considered.
The valve may be used in the liquid, dis-charge, or suction line. A valve applied in the suc-tion line may have a capacity of 0.52 tons, while thesame valve used in the liquid line would have acapacity of 8 tons. Using an oversized valve maymean the valve won’t close properly, not to mentionthat you probably paid for more valve than youneeded.
Should asolenoid valve be
selected based online size?
#10QuickTips
The valve capacity and application should alwaysbe the determining factors when selecting a sole-noid valve. Use this five step process to help makethe correct selection every time:1. type of refrigerant in the system2. application: discharge, liquid, or suction3. flow capacity required4. line size5. electrical specifications

Before leaving the factory, a specificsuperheat setting is made on each andevery Sporlan TEV. A standard super-heat setting has been established forevery size and every thermostaticcharge. This standard setting providesthe proper superheat on the averagesystem to which the particular TEV sizeand charge is likely to be applied.
Therefore, in most cases, a superheat adjustment on the job will notbe necessary. Sporlan recommends a change in the superheatadjustment only after it has been determined that it is required. Acareful measurement of the operating superheat, using the recom-mended procedure, will establish if a change would be beneficial.
To reduce the superheat, turn the adjusting stem COUNTER-CLOCKWISE. To increase the superheat, turn the adjusting stem

CLOCKWISE. When adjusting the valve, make no more than oneturn of the stem at a time and observe the change in superheat close-ly to prevent over-shooting the desired setting. On adjustable TEVs,Sporlan attempts to position the adjusting stem at the half-way pointwhen it is at the standard setting. This allows maximum adjustmentin both directions.
Sporlan supplies a number of OEMs with non-adjustable TEVs.The OEM determines the superheat setting through laboratory test-ing of the unit. Some of these valves can be converted in the field toadjustable models.

Generally speaking, when a manu-facturer installs a Catch-All on apiece of epuipment, the engineersoften (but not always) select the mosteconomical product they feel willhandle their application. Most man-ufacturers employ processes that
minimize the amount of contaminants in the system. By analyzingtheir production methods, decisions are made based on filter driercapability, dimensions, and cost. Often these decisions result in theselection of a smaller sized filter drier, because they, are installed ina controlled environment.
When it becomes necessary to replace a filter-drier in the field, thelikelihood of the presence of contaminants such as mositure, acid,sludge etc. is very real. The Catch-All application tables aredesigned to recommend a filter-drier size that is sufficient to han-dle these problems, and also minimize pressure drop across thedrier.
Since it is wise to err on the side of caution, the technician replac-ing a drier or suction filter in the field is wise to consider the rec-ommendations on the Catch-All package or bulletin 40-10 ratherthan going by what is on the system.
After looking at your applica-tion tables for Catch-All Filter-Driers, I notice there is adramatic difference in the rec-ommendations for OEM com-pared to Field Replacement(See following page).
Why is theresuch a
difference?

Most of the TEVs listed in SporlanCatalog 201 or Bulletin 10-10 will beadjustable unless there is an "N"stamped in the valve body as part ofthe nomenclature (i.e. NSVE-5).Many of the valves made specificallyfor OEM customers are non-
adjustable. One way to tell if a valve is adjustable or non-adjustableis to look at the bottom cap.
Adjustable expansion valves will have a threaded joint between thevalve body and bottom cap as well as a threaded joint betweenthe bottom cap and a hex seal cap that is removable to expose theadjusting stem. See photo of adjustable valve on following page.
Non-adjustable valves on the other hand will generally have onlyone threaded joint between the valve body and bottom cap. Anexception to this rule is a factory adjustable valve with two thread-ed joints and a smooth, round non-removable seal cap. See photoof non-adjustable valve on following page.
Many non-adjustable valves can be converted to adjustable bychanging the bottom cap assembly Contact Sporlan's TechnicalSupport department for more information. They will need all theinformation you can get from the valve's markings to assist you.
CAUTION: Never attempt to determine if a valve is adjustable byremoving the bottom cap assembly unless the system has beenpumped down, it could result in serious injury.

In most cases, the set point for theadjustable thermostatic expansionvalves is midway in the range ofthe adjustment. The valve can bereturned to midway in the adjust-ment range by simply turning theadjustment counter clockwise to the
"fully open" adjustment stop, and then turning the adjustmentclockwise half of the number of complete turns available in theadjustment. The total number of turns from fully open to fullyclosed varies according to valve model, and are listed in the tablebelow.
Caution: Never force the adjustment stem in either direction.Excerting too much force at the adjustment stops on either end canresult in damage to adjustment mechanism.
Please contact Sporlan's Technical Support department for helpwith your specific valve. They will require all of the information youcan get from the markings on the valve.

Can I replacethe power head
on my SporlanTEV and how do
I know whatto get?
With a few exceptions, most Sporlanthermostatic expansion valves man-ufactured after 1993 have replace-able thermostatic elements. Theexceptions are valves with a "H"before the valve nomenclature (i.e.HSVE-10), and the relatively new
Platform valves. The Platform valves can be identified by a stainlesssteel element. The valves with the "H" in the nomenclature havehad the elements soldered to the valve body at the customer'srequest.
Sporlan makes replacement element kits that are available throughAuthorized Sporlan Wholesalers.
The thermostatic elements on Sporlan expansion valves are identi-fied by a series of numbers and letters. The number (i.e. 33, 43, 83,etc.) identifies the element size, while the letters (i.e. VGA, RC, JCP,etc.) identify the regfrigerant and thermostatic charge. A replace-ment element kit can be obtained based on that information. Forexample, a valve with markings on the element of 83 and VCP100will require a KT-83-VCP100 element kit. (For more imformationon element identification, consult Bulletin 210-60.)
If markings on the element are no longer legible, contact Sporlan'sTechnical Support department for help in selecting a replacementelement. They will need all information available from the valvebody, and a description of the application.
#15QuickTips
To completely identify a SPORLAN thermostaticelement the following information is required:
