FOR YOUR SAFETY
Do not store or use gasoline, or other fl ammable vapors and liquids in the vicinity of this or any other appliance. Read product labels for fl ammability and other warnings.
CHILD SAFETY
• Destroy carton, plastic bags, and any exterior wrapping material immediately after the freezer is unpacked. Children should never use these items to play. Cartons covered with rugs, bedspreads,
plastic sheets or stretch wrap may become airtight
chambers, and can quickly cause suffocation.
• Remove all staples from the carton. Staples can cause severe cuts, and destroy finishes if they come in contact with other appliances or furniture.
• An empty, discarded ice box, refrigerator, or freezer is a very dangerous attraction to children.
• Remove and discard any spacers used to secure the shelves during shipping. Small objects are a choke hazard to children.
• Remove the door(s) of any appliance that is not in use, even if it is being discarded.
RISK OF CHILD ENTRAPMENT
Child entrapment and suffocation are not problems of the past. Junked or abandoned refrigerators or freezers are still dangerous – even if they will sit for “just a few days”. If you are getting rid of your old refrigerator or freezer, please follow the instructions below to help prevent ac­cidents:
• Remove the door/lid.
• Leave shelves in place so children may not easily climb inside.

Section 2 Installation Information
Electrical Information
These guidelines must be followed to ensure that safety mechanisms in the design of this freezer will operate properly.
Refer to the serial plate for correct electrical rating. The power cord of the unit is equipped with at three-prong grounding plug for protection against shock hazards. It must be plugged directly in to its own properly grounded three-prong receptacle, protected with a 15 amp time delay fuse or circuit breaker. The receptacle must be installed in accordance with the current edition of the National Electrical Code (NFPA 70) the local codes and ordinances. Consult a qualified electrician. Receptacles with Ground Fault Circuit Interrupters (GFCI) are NOT RECOMMENDED. DO NOT USE AN EXTENSION CORD OR AN ADAPTER PLUG.
If the voltage varies by 10% or more, freezer and/or refrigerator performance may be affected. Operating the freezer with insufficient power can damage the motor. Such damage is not covered under the warranty. If you suspect your voltage is high or low, consult your power company for testing.
To prevent the freezer from being turned off accidentally, do not plug the unit in to an outlet controlled by a wall switch or pull cord.
Do not pinch, knot, or bend the power cord in any manner.
WARNING
Avoid fire hazard or electric shock. Do not use an extension cord or an adapter plug. Do not remove any prong from the power cord.
Figure 2-2. Electrical Receptacle
WARNING
Never unplug the freezer by pulling on the power cord. Always grip the plug firmly and pull straight out from the receptacle.
Turning the control to “OFF” turns off the com­pressor but does not disconnect power to other electrical components.
Leveling
The freezer and/or refrigerator must have all bottom corners resting firmly on a solid floor. The floor must be strong enough to support a fully loaded freezer and/or refrigerator.
It is VERY IMPORTANT for your freezer and/or refrigerator to be level in order to function properly. If the unit is not leveled during installation, the door/lid may be misaligned and not close or seal properly, causing cooling, frost or moisture problems.
After discarding crating screws and wood base, use a carpenter’s level to level the unit from front to back. Adjust the plastic leveling feet in front, ½ bubble higher, so that the door closes easily when left half way open.

Water Supply
The ice maker (if equipped) requires a permanent water supply to function correctly. During installation, establish this water supply by connecting a copper tube from the household water system to a valve at the rear of the unit.
WARNING
To avoid property damage:
• Use copper tubing for the water supply line (plastic tubing is more likely to leak).
Manufacturer is not responsible for any
damage if plastic tubing is used for supply
line.
• Ensure water supply and installation comply with state and local laws and regulations.
• DO NOT install water supply tubing where temperatures fall below freezing.
• Chemicals from a malfunctioning softener can damage the ice maker. If the ice maker is connected to soft water, ensure that the softener is maintained and working properly.
Requirements:
• Access to a cold water line with pressure of 20-120 psi. (System supplied with cold water only.)
• Copper tubing with ¼ inch (6.4mm) Outside Diameter (OD). Length is the distance from the rear of the unit to your household water supply line, plus seven (7) feet (2.1 meters).
• A shut-off valve for the connection between your
household water line and the refrigerator supply line.
DO NOT use a self-piercing shut-off valve.
• A compression nut and ferrule (sleeve) for the water supply connection at the water valve inlet.
To connect the water supply to the rear of the unit (See Figure 2-7a):
1. Ensure that the unit is unplugged.
2. Flush the supply line until water is clear by placing the end of the copper tube in a sink or bucket and opening the shut-off valve. Close shut-off valve when flushing is complete.
3. Remove and discard the plastic cap from the water valve inlet at the rear of the unit.
4. Slide the brass compression nut, then the ferrule (sleeve) onto the copper tube.
5. Push the copper tube into the water valve inlet as far as it will go (¼ inch or 6.4mm).
6. Slide the ferrule (sleeve) into the water valve and
finger-tighten the compression nut onto the valve.
Tighten another half turn with a wrench but DO NOT over-tighten.
7. Secure the copper tube to your units’ rear panel with a steel clamp and screw.
8. Coil the excess copper tubing (about 2½ turns) behind your refrigerator as shown. Arrange coiled tubing to avoid vibration or wear against other surfaces.
9. Open water supply shut-off valve and tighten any connections that leak.
10. Connect unit to home power supply.

Section 2 Installation Information
Connecting the Water Valve to the Ice Maker
For models Serial Number WB92254219 and greater built after June 1, 2009, the units will have a different water valve than earlier production models. The new water valves have a quick connect outlet fitting which takes a standard .255 diameter plastic tube. The old style of water valves required a flanged tube and a threaded nut to make the water connection. (See Figure 2-7b)
Water Line Kit PN 297114101 will still be used to make the water line connections between the new style water valve and ice maker, however the flanged tube will have to be modified as described in the steps below:
1. Using a box cutters or knife, cut the pointed end from the water line just below the raised point. Be sure to cut straight across the water line. Do not leave open/cut end at an angle. (See Figure 2-7c)
2. Remove the cut end and plastic nut from the water line and discard.
3. Measure 11/16” from the end of the water line and place a mark on the line with a permenent marker.
4. Insert the modified water line into the push-type fitting on the new valve, making sure that the water line is pushed in up to the mark.
5. Inspect for leaks once water supply is turned on.
The water valve on the left is the old style
threaded outlet connection. The water valve on
the right has the push-type outlet fitting.

Leveling The Refrigerator And Freezer
1. Remove the plastic top hinge covers and replace with the supplied silver hinge covers (I).
2. Remove the plastic toe grill panels at the bottom of each unit. Save the four screws as they will be used later in the installation.
3. Place a carpenter’s level across the top of the door. Using a tape measure, adjust all four levelers so that each door is level and to a height of 69-3/8” across top front edge of door. (See Figures 2-24 and 2-25).
Figure 2-24.
4. Place a carpenter’s level vertically on the front of the door and level so that the front surface of door is vertical. Recheck to make sure top front edge of door is still at a height of 69-3/8”. Adjust as necessary. (See Figures 2-24 and 2-25).
Figure 2-26.
Final Positioning
1. Connect the ice maker water lines (if so equipped). Refer to the “Connecting Ice Maker To Water Supply” in the literature bag for proper hook-up of water filter and ice maker to your household water supply before sliding the units in place. Plug power cords into their receptacles prior to pushing unit fully into place. If your receptacle is not centered in the space, make sure to slide the unit on the side opposite the receptacle into place first. Slide units into place one at a time. Slide units carefully to avoid pinching or damaging the ice maker and water filter hoses on the back of the unit.
2. Re-check the level of each unit. Depending on the flatness of your floor, you may need to readjust several times before achieving an acceptable state of levelness and alignment. Allow 3/8” gap between units for center trim (G or H). (See Figure 2-27 ).
3. In the case of a side-by-side installation of two units, install the magnetic center trim piece (G or H) in the gap between both units. The trim piece should be flush with tops of units and fit just above toe grill.

Section 3 Mechanical Control
Temperature Control
The temperature control is located inside the refrigerator compartment. The temperature is factory preset to provide satisfactory food storage temperatures. However, the temperature control is adjustable to provide a range of temperatures for your personal satisfaction. If a colder temperature is desired, turn the temperature control knob toward COLDEST and allow several hours for temperatures to stabilize between adjustments.
Figure 3-1. Control Knob
Defrost Timing
An automatic 30 minute defrosting period is initiated after every 12 hours of compressor running time. During the defrosting period, a thermostat will switch the defrost heater off after the frost on the evaporator has melted. The defrost thermostat closes at 10ºF and opens at 50ºF.

Section 4 Refrigeration
NOTE
Instructions given here are furnished as a guide. Persons attempting to use these instructions to make repairs to the sealed refrigeration system should have a working knowledge of refrigeration and previous training on sealed system repair, and an EPA certification for servicing refrigeration systems.
IMPORTANT
Effective July 1, 1992, the United States clean air act governs the disposal of refrigerants such as R-134a. Therefore, when discharging or purging the sealed system use an EPA approved refrigerant recovery system as outlined in the final rule on the protection of stratospheric ozone and refrigerant recycling, which was published in the Federal Register May 14, 1993.
NOTE
Electrolux Home Products Inc. does not permit the use of recovered refrigerant in the servicing of our products for in-warranty and out-of-warranty repairs or for products covered by service contracts. Therefore, only new refrigerant or refrigerant that has been reclaimed back to new specifications by a refrigerant manufacturer is to be used.
Definitions
Recovery:
To remove refrigerant in any condition from a system and store it in an external container without necessarily testing or processing it in any way.
Recycling:
To clean refrigerant for reuse by oil separation and single or multiple passes through devices, such as replaceable core filter-driers, which reduce moisture, acidity and particulate matter. This term usually applies to procedures implemented at the field job site or at a local service shop.
Safety Warnings
Compressor Testing
Whenever testing a compressor, extreme caution should be used to prevent damaging the terminals. A compressor with a damaged terminal or a grounded winding can expel a terminal from its insulated housing when the compressor is energized. If this happens, a mixture of refrigerant and oil will be released that could be ignited by an external heat source (open flame, heater, etc.). Also, if there is air in the system when this happens, a spark at the compressor shell could ignite the refrigerant and oil mixture.
Charging Sealed Systems
Overcharging a refrigeration system with refrigerant can be dangerous. If the overcharge is sufficient to immerse the major parts of the motor and compressor in liquid refrigerant, a situation has been created which, when followed by a sequence of circumstances can lead to the compressor shell seam separating.
A hydraulic block occurs, preventing the compressor from starting. This condition is known as locked rotor. Electric current continues to flow through the compressor motor windings which become, in effect, electric resistance heaters. The heat produced begins to vaporize the excess refrigerant liquid causing a rapid increase in system pressure. If the compressor protective devices fail, the pressure within the system may rise to extremes far in excess of design limits. Under these conditions, the weld seam around the compressor shell can separate with explosive force, spewing oil and refrigerant vapor which could ignite.
To eliminate this exceedingly rare but potential hazard, never add refrigerant to a sealed system. If refrigerant is required, evacuate the existing charge and recharge with the correct measured amount of the refrigerant specified for the system.
Reclaim:
To reprocess refrigerant to new product specifications by means which may include distillation, will require chemical analysis of the refrigerant to determine that appropriate product specifications are met. This term usually implies the use of processes or procedures available only at a reprocessing or manufacturing facility.

Soldering
WARNING
Wear approved safety glasses when working with or on any pressurized system or equipment. Have an approved dry type fire extinguisher handy when using any type of gas operated torch.
1. All joints to be soldered must have proper fit. Clearance between tubes to be soldered should be from .001” to .006”. It is not practical to actually measure this; however, you do not want a dry fit or loose fit. Tubing joints should overlap about the
distance of their diameter except for restrictor tubes,
which should be inserted 1.25”.
2. Clean all joint areas with fine steel wool or
preferably an abrasive cloth, such as grit cloth No. 23 or Scotch-Brite.
3. Apply a thin film of liquid flux recommended for
silver soldering to surfaces to be joined and to surfaces immediately adjacent to joint.
CAUTION
During application of heat, use wet cloths to prevent heat from conducting to areas other than the soldered joint. Use a sheet of metal or torch guard pad as a heat deflector to keep flame away from inflammable materials and painted surfaces.
Basic Components
The basic components of a refrigerator/freezer are a compressor, condenser, evaporator, heat exchanger (capillary tube and suction line) and drier.
Refrigerant Cycle
The refrigerant cycle is a continuous cycle that occurs whenever the compressor is in operation. Liquid refrigerant is evaporated in the evaporator by the heat that enters the cabinet through the insulated walls and by the heat from product load and door openings. The refrigerant vapor is then drawn from the evaporator, through the suction line to the compressor. Compression raises the pressure and temperature of the vapor in the compressor and the vapor is then forced through the discharge valve into the discharge line and into the condenser. Air passing over the condenser surface removes heat from the high pressure vapor which then condenses to a liquid. The liquid refrigerant then flows from the condenser to the evaporator through the small diameter liquid line (capillary tube). Before it enters the evaporator, the liquid refrigerant is sub-cooled in the heat exchanger by the low temperature suction vapor in the suction line. When refrigerant is added, the frost pattern will improve, the suction and discharge pressures will rise, the condenser will become hot and the wattage will increase.
4. Align tubing so no stress is on joint. Do not move tubing while solder is solidifying or leaks will result.
5. Use a torch of adequate capacity so joint can be quickly heated with a minimum of heat travel to other points. Use a good grade of silver solder.
6. Solder connections. If tubing is properly cleaned and fluxed, solder will flow readily. Use only enough solder to make a good bond.
7. Allow joint to cool, then wash exterior with water to remove flux.
4-2

Section 4 Refrigeration
Low/High Side Leak or Undercharge
A loss of refrigerant can result in any of the following:
1. Excessive or continuous compressor operation.
2. Above normal freezer compartment temperature.
3. A partially frosted evaporator (depending on amount of refrigerant loss).
4. Below normal freezer compartment temperature.
5. Low suction pressure (vacuum).
6. Low wattage.
The condenser will be “warm to cool”, depending on the amount of refrigerant lost.
In the case of a low side refrigerant leak resulting in complete loss of refrigerant, the compressor will run but will not refrigerate. Suction pressure will drop below atmospheric pressure and air and moisture will be drawn into the system saturating the filter drier.
If there is reason to believe the system has operated for a considerable length of time with no refrigerant and the leak occurred in the low side of the system, excessive amounts of moisture may have entered the system. In such cases the two stage service Dryer Filter part number 5303918288 and vacuum procedure listed under Refrigerant Leaks need to be followed to prevent repetitive service.
If a slight undercharge of refrigerant is indicated and no leak can be found after a thorough leak test, the charge can be corrected without changing the compressor.
If a high side leak is located and some refrigerant remains in the system it is not necessary to change the compressor.
Testing for Refrigerant Leaks
NOTE
The line piercing valve (clamp-on type) should be used for test purposes only. It must be removed from system after it has served its purpose.
If the system is diagnosed as short of refrigerant and the system has not been recently opened, there is probably a leak in the system. Adding refrigerant without first locating and repairing the leak or replacing the component will not permanently correct the difficulty. The leak must be found. Sufficient refrigerant may have escaped to make it impossible to leak test effectively. In such cases, add a ¼” line piercing valve to the compressor process tube. Add sufficient refrigerant vapor to increase the pressure to 40 to 50 lb. per sq. in. Check the low side for leaks. Run the compressor 2 or 3 minutes and check the high side for leaks. Recover refrigerant using an EPA approved recovery system.
Compressor Oil Contamination
To check for contamination, obtain oil sample from old compressor.
1. If the oil has burned odor, but no color change or residue — follow instructions on page 4-5 “Installing A New Compressor”.
2. If oil has a burned odor and a sugar or gritty feel as well as showing signs of contamination (dark color), follow instructions in next section, To Flush The System. Remove as much of contamination as
possible from system before installing new compressor and filter-drier.
CAUTION
NEVER install a new compressor without first checking for possible system contamination.
NOTE
It is recommended that system be flushed with dry Nitrogen. However, if refrigerant is used to flush the system you must look at the serial plate to see what type of refrigerant is used in the system. This is the only refrigerant that can be used to flush the system and it must be recovered.
4-3
Page 30
Section 4 Refrigeration
To Flush The System
CAUTION
Use extreme care when using Dry Nitrogen to flush systems. Pressure in nitrogen cylinder could be as high as 2000 psi. Nitrogen cylinder must be equipped with approved pressure regulator and pressure relief valve. Ensure that your hoses have adequate ratings for pressure involved and that all of your equipment is in good condition. The end of the flushing hose on this tank regulator must be equipped with a hand shut-off valve (Robinair No. 40380). Close hand shut-off valve and adjust nitrogen regulator to correct pressure before proceeding with flushing procedure.
To Use Dry Nitrogen To Flush The System:
1. Remove compressor and filter-drier. Connect process coupling to outlet tube of condenser.
2. Fasten cloth over other end of coil to prevent old oil from spraying over room.
3. Connect hand shut-off valve on flushing hose to process coupling.
4. Slowly open hand shut-off valve and allow nitrogen to flow through condenser until discharge is clear.
CAUTION
DO NOT exceed 300 Psi.
To Use Refrigerant To Flush The System:
CAUTION
Refrigerant used for flushing must be recovered into a recovery system. Meter amount of refrigerant used for flushing with your charging cylinder. DO NOT OVERFILL THE BAG.
1. Disconnect the suction and discharge lines from the compressor and remove the filter-drier. Connect process coupling to outlet and inlet tube of
condenser.
2. Connect hose to outlet process coupling and
charging cylinder. Connect another hose to inlet
coupling and recovery system.
3. Open charging cylinder and allow refrigerant to flow through condenser until discharge into bag is clear.
NOTE
The line piercing valve (clamp-on type) should be used for test purposes only. It must be removed from system after it has served its purpose.
4. Disconnect capillary tube from evaporator. Flush evaporator in same manner as condenser.
5. Flush cap tube. This is only possible if you have proper service valve adapter.
6. Reassemble system.
5. Disconnect cap tube from evaporator. Flush evaporator in same manner as condenser.

Installing a New Compressor
NOTE
Entirely new compressors have been developed or use with R-134a and Ester oil refrigeration systems. Both compressor and electric motor have been modified. Old compressors intended for R-12 refrigerant must not be used for new systems charged with R-134a.
Replacement of compressor and installation of filter-drier must be done in a continuous sequence so system is exposed to atmosphere no longer than necessary.
All replacement compressors are shipped with rubber plugs in the suction, discharge and process tubes and contain the correct oil charge and a holding charge of inert gas. Compressors have a low-side process tube attached to the compressor shell. A high-side process tube is attached to the filter-drier.
WARNING
Do not operate reciprocating compressor when charging liquid refrigerant into system through its process tube.
Replacement compressors for refrigerators/freezers may have an oil cooler even if the original compressor did not. If the product is not equipped for an oil cooler, leave the plastic caps in place and install the compressor connecting only to the suction and discharge lines of the new compressor.
NOTE
The following instructions are generalized to help the technician understand the procedures of sealed system repairs. See Section 5 Component Teardown on the exact steps of accessing the components of the refrigeration system.
A new compressor which is cold (e.g. after having been kept in a cold service van) should be left to warm to the surrounding temperature before the plugs on the compressor connections are removed. This will help prevent condensation from forming in the oil and the compressor. Also, avoid opening the system when any of the components or lines are cold.
NOTE
Release holding charge (release slowly to avoid oil discharge) on new compressor to ensure there is no leak in seam or tubing. Reinstall rubber plug.
1. Disconnect electrical supply to refrigerator/freezer.
2. Remove compressor access panel.
3. Remove all components needed to pull the compressor assembly from the unit.
4. Pull compressor assembly straight out.
5. Recover refrigerant by using EPA approved recovery system.
NOTE
Before installing the replacement compressor remove the discharge plug and check for the pop sound of the inert gas leaving the compressor.
DO NOT use compressor if you do not hear this sound.
If the compressor checks OK, reinstall the plug. Do not remove any of the plugs again until the compressor is in position and you are ready to braze the lines.
CAUTION
On R-134a systems, compressor must NOT be left open to atmosphere for more than 10 minutes to prevent moisture contamination of oil.
If low-side process tube is too short, silver solder four inch piece of tubing onto process tube at this time.
6. Remove leads from compressor motor terminals.
7. Remove mounting clips and washers.
8. After refrigerant is completely recovered, cut suction and discharge lines as close to compressor
as possible. Leave only enough tubing to pinch off and seal defective compressor. Plug or tape any open system tubing to avoid entrance of moisture and air into system. Remove inoperable
compressor and transfer mounting parts to new
compressor.
9. Install new compressor in exact same manner as original compressor.
4-5
Page 32
Section 4 Refrigeration
10. Reform both suction and discharge lines to align with new compressor. If they are too short, use additional lengths of tubing. Joints should overlap
0.5” to provide sufficient area for good solder joint. Clean and mark area where tubing should be cut. Cut tubing with tubing cutter. Work as quickly as possible to avoid letting moisture and air into the system.
11. Solder all connections according to soldering
procedure.

Page 34
Section 4 Refrigeration
CAUTION
Check the serial plate for the correct refrigerant type. It is extremely important to verify the type of refrigerant in the system before starting any sealed system repairs.
With the possible exception of the vacuum pump, all service equipment that comes in contact with R-134a during evacuation and recharging must be dedicated. Accordingly, R-134a will require a dedicated charging cylinder, manifold gauge set, process tube adapters, and hoses. Any residual mineral oil on other tools (tubing cutter, etc.) must be thoroughly cleaned off before using on R-134a/ Ester oil systems. It will be necessary to check with the manufacturer of your vacuum pump for refrigerant and oil compatibility issues.
If you use a vacuum pump with mineral oil to evacuate an R-134a system, it is ABSOLUTELY ESSENTIAL to have a shut-off valve between the pump and your manifold gauge set as shown on page 4-10. The hand valve must be closed during all times when the vacuum pump is not operating. This will prevent the migration of mineral oil vapor into the R134a/Ester oil system. If the vacuum pump should stop during evacuation for any reason, the hand pump shut-off valve must be closed immediately.
Insure that your refrigeration hoses are specified for use with R-134a refrigerant. Research has shown that compounds in standard refrigeration hoses may enter sealed systems and ultimately restrict the cap tube in an R-134a system.
Equipment Needed for Evacuation & Recharging:
• Heated charging cylinder
• Standard 3-port manifold gauge set:
- 4 charging hoses
- Tee fitting with valve core stem removed (Robinair No. 40396)
- Hand shut-off valve (Robinair No.40380)
• Two stage vacuum pump
• Process tube adapter kit (Robinair No.12458)
• Tubing cutter
• Pinch-off tool capable of making leak proof seal
• Complete brazing torch set
• Small 3-corner file
• Grit cloth or Scotch-Brite
• 45% silver solder and flux
• Heat Gun
Installing Evacuation and Recharging Equipment
1. Disconnect refrigerator/freezer from electrical supply.
2. If compressor was replaced, install correct sized process tube adapter on process tube.
If compressor was not replaced, cut process tube
with tubing cutter leaving as much tube as possible and install correct size process tube adapter.
3. Install correct sized process tube adapter on
high-side process tube.
4. Attach refrigeration service gauge manifold to system in following order:
• Low-side (compound gauge) hose to suction side process tube adapter.
• High-side (pressure gauge) hose to high-side process tube adapter.
• Center port manifold hose before hand shut-off valve to charging cylinder.
• Center port manifold hose after hand shut-off valve to vacuum pump.

Section 4 Refrigeration
WARNING
R-134a systems are particularly susceptible to moisture contamination which can only be prevented by evacuating the System for a minimum of 30 minutes to attain a minimum
29.9 inch (500 micron or lower) vacuum.
Evacuating System
To achieve the required levels of evacuation, a properly maintained two stage vacuum pump in good condition is required. It is absolutely essential to maintain your vacuum pump according to the manufacturer’s instructions including required oil changes at the recommended intervals. Vacuum pump oil should always be changed after evacuating a contaminated system.
Vacuum pump performance should be checked periodically with a micron gauge.
1. Make certain that charging cylinder valve, hand shut-off valve, and manifold gauge valves are closed.
2. Start vacuum pump.
3. Open hand shut-off valve and slowly open both manifold valves, turning counterclockwise, for two
full rotations.
CAUTION
If high vacuum equipment is used, just crack both manifold valves for a few minutes and then open slowly for the two full turns counterclockwise. This will prevent the compressor oil from foaming and being drawn into the vacuum pump.
4. Operate vacuum pump for a minimum of 30 minutes to a minimum of 29.9” (500 micron) vacuum.
5. Close hand shut-off valve to vacuum pump. Watch compound gauge for several minutes. If reading rises, there is a leak in the system, go to step 6. If no leak is indicated, stop vacuum pump. System is now ready for charging.
6. If a leak is indicated, stop vacuum pump and
introduce a small charge of refrigerant into system
by cracking valve on bottom of charging cylinder until system is pressurized to 40 or 50 lbs psi.
7. Leak test low-side. Close compound gauge. Run compressor for a few minutes and leak test
high-side. When leak is found, recapture refrigerant
using EPA approved recovery system. Repair and go back to step 1.
Charging The System
CAUTION
Check the serial plate for the correct refrigerant type. It is extremely important to verify the type of refrigerant in the system before starting any sealed system repairs. After charging the system with liquid be certain to wait at least 5 minutes before starting the compressor to give the refrigerant a chance to disperse throughout the system. Otherwise the compressor could be damaged by attempting to pump excessive quantities of liquid.
Preparing The Charging Cylinder:
1. Make certain that hand shut-off valve to vacuum pump is closed.
2. Close high-side manifold gauge valve.
3. Set charging cylinder scale to pressure indicated on cylinder pressure gauge.
4. Observe refrigerant level in sight glass. Subtract amount to be charged into system and note shut off point.
5. Open charging cylinder valve slowly and allow
proper charge to enter system.
6. As soon as refrigerant in sight glass has gone down to predetermined level, close charging cylinder valve.
WARNING
Disconnect the charging cylinder heater at this time to prevent the cylinder pressure from exceeding its maximum limits.
7. Allow system to sit for five minutes.
8. Turn on refrigerator compressor. Run compressor for a few minutes and monitor system pressures.
9. When satisfied that the unit is operating correctly, clamp the high-side process tube with the pinch-off tool while the unit is still running.
4-9
Page 36
Section 4 Refrigeration
10. Slowly open the high-side manifold gauge valve to allow the compressor to remove any refrigerant trapped in the high-side hose and the process
fitting.
11. Close both of the manifold gauge valves. If the high-side gauge reading rises, the pinch-off must be corrected before proceeding.
12. Remove the high-side process tube adapter and
solder the process tube closed.
13. Clamp the low-side process tube with the pinch-off tool while the unit is running. Remove the low-side process tube adapter and solder the process tube closed.
14. Check the process tubes for refrigerant leaks.
Final Leak Test
1. With the refrigerator/freezer turned OFF, leak test all low-side system components.
2. Turn the unit ON and run until the condenser is warm. Leak test the high-side system components.

Verify Refrigerant Type In The System
CAUTION
R-134a and R-12 are completely incompatible. Before starting any sealed system repair, it is extremely important to check serial plate of product to verify the type of refrigerant in the system.
Dedicated Equipment
R-134a must not be mixed with other types of refrigerants. R-134a must be recovered in dedicated and properly identified recovery bags and tanks.
It will be necessary to check with the manufacturer of your recovery equipment to determine R-134a compatibility. Some recovery equipment manufacturers have changeover instructions for switching between refrigerant types. Protect yourself and your equipment by following all manufacturer guidelines.
Also, ensure that your refrigeration hoses are specified for use with R-134a refrigerant. Research has shown that compounds in standard refrigeration hoses may enter sealed systems and ultimately restrict the cap tube in an R-134a system.
R-134a Refrigeration Systems
The sealed refrigeration system will consist of the same basic components being utilized in the R-12 systems.
There is a 10% to 15% discharge pressure increase using R-134a, with a 5% to 10% decrease in suction pressure when compared to the same product with an R-12 system operating at 90°F (32°C) ambient temperature conditions. Lower suction pressures result from the lower density of R-134a refrigerant which effects refrigerant flow rate. R-134a systems commonly operate in a 1”-2” vacuum on the suction side.
Products using R-134a refrigerant will generally have a longer capillary tube to maintain a similar flow rate and some models will have a larger condenser to reduce the discharge pressures and lower start-up sound transmission.
Miscibility of R-134a and Ester Oil
A special synthetic oil known as Ester oil is used as a lubricant in refrigeration systems operating on R-134a. Ester oils are produced from alcohols and fatty acids and are available in several different variants. Ester oils have a pleasant aroma reminiscent of fruit.
Ester oils generally include various types of additives for improving certain properties such as viscosity, temperature sensitivity, etc. These additives are often aggressive, and skin contact with Ester oils should therefore be avoided.
One of the most important requirements made on a refrigerant system is that the oil mix with the refrigerant. Since mineral oil and ordinary synthetic oil DO NOT mix with R-134a, Ester oil is used for lubrication. Ester oil dissolves in R-134a.
Ester oil is broken down by chlorine and cannot be used with R-12 (R-12 contains chlorine) or any other compound containing chlorine. Therefore, R-134a refrigeration systems have virtually no tolerance for chlorine molecules from CFC refrigerants (R-134a is an HFC and contains no chlorine).
CAUTION
During R-134a service, it is extremely important to avoid using equipment that may contain residual amounts of mineral oil, CFC’s or HCFC’s which could enter and contaminate the sealed system.
4-11
Page 38
Section 4 Refrigeration
For example, hoses that were used for a refrigeration system operating on R-12 may contain small quantities of mineral oil which can block the capillary tube in a system operating on R-134a. As little as one milligram may be sufficient to cause a blockage. In addition, sealed system components that have been used with CFC systems must not be used with R-134a systems. These components may contain residual amounts of refrigerant and oil which could damage an R-134a system.
At the earliest stage of development work on R-134a, tests were carried out on a different type of synthetic oil known as Poly-Alkaline Glycol (PAG). This oil is also used in certain air conditioning systems for cars. PAG and Ester oil DO NOT mix with one another. Service equipment used for R-134a / Ester oil must not come into contact with PAG.
Water In The Refrigeration System
Even in very small quantities, water in any refrigeration system can cause the following problems:
• Ice plugs in capillary tubes.
• Copper plating in compressor.
• Reactions with organic materials in systems.
• Corrosion of metals.
To achieve the required 29.9 inch (500 micron) vacuum, a properly maintained two-stage vacuum pump in good condition is required. A two stage pump can reach a deeper vacuum than a single stage because the exhaust from the first pumping stage is discharged into the second pumping stage. This means the second stage begins pumping at a lower pressure so a lower ultimate vacuum can be achieved.
R-134a and Ester oil will aggravate the problem of water in the refrigeration system. Ester oil may react with water vapor and is hygroscopic (it will absorb water if it comes in contact with humid air). Water is also more soluble in R-134a than R-12.
To minimize the water content whenever service work is performed, the refrigeration system should always be thoroughly evacuated through process tube adapters on both the high and low sides of the system. Evacuation must be for a minimum of 30 minutes to at least a 29.9 inch (500 micron) vacuum.
4-12
Page 39
Section 4 Refrigeration
Vacuum Pump Maintenance
It is absolutely essential to maintain your vacuum pump according to the manufacturer’s instructions including required oil changes at the recommended intervals. Vacuum pump oil should always be changed after evacuating a contaminated system. Vacuum pump performance should be checked periodically with a micron gauge.
Vacuum pump suppliers may or may not recommend changing the vacuum pump oil to the same type that’s in the system being evacuated. Some manufacturers may recommend a vacuum pump that’s dedicated to R-134a systems.
Robinair has stated that their current and discontinued vacuum pump models, using mineral oil currently specified for use in their vacuum pumps, can be used to evacuate R-134a/Ester oil systems. Robinair also states that it is acceptable to alternate between evacuating R-12/mineral oil and R-134a/Ester oil systems without adversely effecting the vacuum pump’s performance.
For other brands of vacuum pumps, check with the manufacturer for restrictions and guidelines when using with R-134a.
Refrigerant Leaks
A system with R-134a and Ester oil will become saturated with moisture much faster than a system with R-12 and mineral oil. If your leak was in the low side of the refrigeration system when the compressor is running the pressure in the low side will go into a vacuum. As additional refrigerant leaks out the system will go deeper into a vacuum. The system running in this vacuum will allow air and moisture to be pulled into the sealed system. The moisture pulled in can then be mixed in to the Ester oil in the compressor.
If the product has had a low side leak you will need to install the two stage service dryer filter part number
5303918288. You must heat the crankcase area of the compressor using a heat gun on the high heat setting throughout the 30 minutes you are running your vacuum pump to pull a vacuum on the system. Every 4 to 5 minutes while you are running your vacuum pump and heating the crankcase area, shake the compressor. By heating the crankcase you are heating the oil in the compressor. This will drive the moisture out of the oil. By shaking the compressor this will allow the moisture to come to the top of the oil faster so the vacuum pump can remove the moisture from the system.
CAUTION
If you use a vacuum pump with mineral oil to evacuate an R-134a system, it is ABSOLUTELY ESSENTIAL to have a shut-off valve between pump and your manifold gauge set as shown on page 4-10. The hand valve must be closed during all times when vacuum pump is not operating. This will prevent migration of mineral oil vapor into R134a/Ester oil system. If vacuum pump should stop during evacuation for any reason, the hand pump shut-off valve must be closed immediately.
Electrolux Home Products does not approve the use of the Sweep Charge for sealed system repair. This method of servicing sealed systems is often used to repair products in the field. The Sweep Charge does not adequately remove moisture from the oil in the compressor. In a R-134a system you will need to replace the compressor if the product has had a low side leak and you are servicing with the Sweep Charge procedure.
R-134a refrigerant molecules are smaller than R-12 molecules. This means that R-134a will pass more minor leaks and the rate of flow will be greater than for R-12. Therefore, it is now more important than ever to follow good brazing practices. Use a good grade of silver solder. A 45% silver solder is recommended.
4-13

Section 4 Refrigeration
Leak Detection
R-134a system leaks can be pinpointed by means of an electronic leak detector or by bubble solution.
Electronic leak detectors for R-134a service are currently available from several manufacturers. The least expensive models are non-selective detectors that will detect any type of emission or vapor present, regardless of its chemical composition. Some non-selective detectors designed for use with R-12 may have a much lower sensitivity when used with R-134a. However, newly designed detectors with good R-134a sensitivity are now available. Be sure to consult with the manufacturer before selecting or using a non-selective detector with R-134a.
Halogen-specific detectors use a specialized sensor that allows detection of compounds containing chlorine, fluorine, bromine, and iodine without being activated by other species. The major advantage of this type of detector is a reduction in the number of “nuisance alarms”. Halogen-specific detectors are generally more expensive than non-selective detectors but feature higher sensitivity.
R-134a properties
The properties of R-134a are very similar to those of R-12. The principal data for the two refrigerants are shown in the chart below.

Page 42
Section 4 Refrigeration
Inhalation Toxicity
HFC-134a poses no acute or chronic hazard when it is handled in accordance with DuPont recommendations and when exposures are maintained at or below the DuPont Acceptable Exposure Limit (AEL) of 1,000 ppm (8 and 12 hour Time-Weighted Average or TWA).
An AEL is an airborne exposure limit established by DuPont scientists that specifies time-weighted average (TWA) airborne concentrations to which nearly all workers may be repeatedly exposed without adverse effects. The AEL for HFC-134a has the same value as the Threshold Limit Values (TLVs) established for CFC-12 and HCFC-22. TLVs are established by the American Conference of Governmental and Industrial Hygienists (ACGIH).
However, inhaling high concentrations of HFC-134a vapor may cause temporary central nervous system depression with narcosis, lethargy and anesthetic effects. Other effects that may occur include dizziness, a feeling of intoxication and a loss of coordination. Continued breathing of high concentrations of HFC-134a vapors may produce cardiac irregularities (cardiac sensitization), unconsciousness, and with gross overexposure, death. Intentional misuse or deliberate inhalation of HFC-134a may cause death without warning. This practice is extremely dangerous.
If you experience any of the initial symptoms, move to fresh air and seek medical attention.
Cardiac Sensitization
If vapors are inhaled at a concentration of 75,000 ppm, which is well above the AEL, the heart may become sensitized to adrenaline, leading to cardiac irregularities and, possibly, to cardiac arrest. The likelihood of these cardiac problems increases if you are under physical or emotional stress.
Medical attention must be given immediately if exposed to high concentrations of HFC-134a. DO NOT treat with adrenaline (epinephrine) or similar drugs. These drugs may increase the risk of cardiac arrhythmia and cardiac arrest. If the person is having difficulty breathing, administer oxygen. If breathing has stopped, give artificial respiration.
Spills or Leaks
If a large release of vapor occurs, such as from a large spill or leak, the vapors may concentrate near the floor or low spots and displace the oxygen available for breathing, causing suffocation.
Evacuate everyone until the area has been ventilated. Use blowers or fans to circulate the air at floor level. DO NOT re-enter the affected area unless you are equipped with a self-contained breathing apparatus or unless an area monitor indicates that the concentration of HFC-134a vapors in the area is below the AEL.
Always use self-contained breathing apparatus or an air-line mask when entering tanks or other areas where vapors might exist. Use the buddy system and a lifeline. Refer to the Material Safety Data Sheet (MSDS) for HFC-134a for more information.
HFC-134a vapors have a slightly sweet odor that can be difficult to detect. Therefore, frequent leak checks and the installation of permanent area monitors may be necessary in enclosed spaces. Refer to ASHRAE Standards 15 and 34 for refrigeration machinery rooms.
To ensure safety when working with HFC-134a in enclosed areas:
1. Route relief and purge vent piping (if present)
outdoors, away from air intakes.
2. Make certain area is well ventilated, using auxiliary ventilation if needed to move vapors.
3. Make sure area is clear of vapors prior to beginning work.
4. Install air monitoring equipment to detect leaks.
Skin and Eye Contact
At room temperature, HFC-134a vapors have little or no effect on the skin or eyes. However, in liquid form, HFC-134a can freeze skin or eyes on contact, causing frostbite. Following contact, soak the exposed area in lukewarm water, not cold or hot. If medical treatment cannot begin immediately, apply a light coat of a nonmedicated ointment, such as petroleum jelly. If the exposed area is in a location where the presence of the ointment would be awkward, such as on the eye, apply a light bandage. In all cases of frostbite, seek medical attention as soon as possible.
4-16
Always wear protective clothing when there is a risk of exposure to liquid HFC-134a. Where splashing is possible, always wear eye protection and a face shield.
Page 43
Section 4 Refrigeration
Combustibility of HFC-134a
HFC-134a is nonflammable at ambient temperatures and atmospheric pressure. However, tests have shown HFC-134a to be combustible at pressures as low as 5.5 psi (139.3 kPa absolute) at 177°C (350°F) when mixed with air at concentrations generally greater than 60% volume air. At lower temperatures, higher pressures are required for combustibility. (HCFC-22 is also combustible at pressures above atmospheric in the presence of high air concentrations). Test results and calculations have shown:
• At ambient temperature, all concentrations of HFC-134a in air are nonflammable at pressures
below 15 psi (205 kPa absolute).
• Combustible mixtures of air and HFC-134a will not form when liquid HFC-134a is pumped into closed vessel if initial air pressure in vessel is limited to one atmosphere absolute and final pressure is limited to 300 psi (2,170 kPa absolute). If initial air pressure is greater than one atmosphere,
combustible mixtures may form as tank is filled.
Based on above information, the following operating practices are recommended:
Leak Testing
• Equipment should NEVER be leak tested with a pressurized mixture of HFC-134a and air. HFC-134a may be safely pressured with dry nitrogen.
Filling and Charging Operations
• Before evacuating cylinders or refrigeration equipment, any remaining refrigerant should be
removed by recovery system.
• Vacuum pump discharge lines should be free of restrictions that could increase discharge pressures above 15 psi (205 kPa) and result in formation of combustible mixtures.
• Cylinders or refrigeration equipment should
normally be evacuated at start of filling, and should
never be filled while under positive air pressure.
• Final pressures should not exceed 300 psi
(2,170 kPa).
• Filled cylinders should periodically be analyzed for air (nonabsorbable gas or NAG).
Refrigerant Recovery Systems
Efficient recovery of refrigerant from equipment or containers requires evacuation at the end of the recovery cycle. Suction lines to a recovery compressor should be periodically checked for leaks to prevent compressing air into the recovery cylinder during evacuation. In addition, the recovery cylinder pressure should be monitored, and evacuation stopped in the event of a rapid pressure rise indicating the presence of noncondensable air. The recovery cylinder contents should then be analyzed for NAG, and the recovery system leak checked if air is present. DO NOT continue to evacuate a refrigeration system that has a major leak.
Bulk Delivery and Storage
• Tanks should normally be evacuated at start of filling, and should never be filled while under positive air pressure.
• Tank pressure should never be allowed to exceed 300 psi (2,170 kPa) when filling with HFC-134a. Relief devices on either tanks or HFC-134a supply system usually prevent this.
• Tank pressures should be monitored routinely.
• Air lines should never be connected to storage tanks.
Thermal Decomposition
HFC-134a vapors will decompose when exposed to high temperatures from flames or electric resistance heaters. Decomposition may produce toxic and irritating compounds, such as hydrogen fluoride. The pungent odors released will irritate the nose and throat and generally force people to evacuate the area. Therefore, it is important to prevent decomposition by avoiding exposure to high temperatures.

Section 7 Troubleshooting
Problem
Freezer/refrigerator compressor does not run.
Freezer/refrigerator runs too much or too long.
Cause
Unit is plugged into a circuit that has a ground fault interrupt.
Temperature control is in the “OFF” position.
Unit may not be plugged in, or plug may be loose.
House fuse blown or tripped circuit breaker.
Power outage.
Room or outside weather is hot.
Unit has recently been disconnected for a period of time.
Large amount of warm or hot food have been stored recently.
Door is opened too frequently or kept open too long.
Correction
Use another circuit. Check circuit for proper voltage.
Set control to a temperature setting. Instruct customer.
Ensure plug is tightly pushed into outlet.
Check/replace fuse with a 15 amp time delay fuse.
Reset circuit breaker.
Check house lights. Call local Electric Company.
It’s normal for the freezer/refrigerator to work
harder under these conditions.
It takes 4 hours for the unit to cool down completely.
Warm food will cause unit to run more until the
desired temperature is reached.
Warm air entering the unit causes it to run more.
Open the door less often.
Interior freezer/refrigerator temperature is too cold.
Interior freezer/refrigerator temperature is too warm.
Unit door may be slightly open.
Temperature control is set too low.
Freezer/refrigerator gaskets are dirty, worn, cracked or poorly fitted.
Temperature control is set too low.
Temperature control is set too warm.
Door is opened too frequently or kept open too long.
Unit door may be slightly open.
Large amount of warm or hot food have been stored recently.
Unit has recently been disconnected for a period of time.
See Problem section “Door will not close”.
Set control to a warmer setting. Allow several hours for the temperature to stabilize.
Clean or change gasket. Leaks in the door seal
will cause unit to run longer in order to maintain desired temperature.
Set control to a warmer setting. Allow several hours for the temperature to stabilize.
Set control to a colder setting. Allow several hours for the temperature to stabilize.
Warm air entering the unit causes it to run more.
Open the door less often.
See Problem section “Door will not close”.
Wait until the unit has had a chance to reach its
selected temperature.
Unit requires 24 hours to cool down completely.
Freezer/refrigerator external surface temperature is warm.
The external freezer/refrigerator walls can be as much as 30ºF warmer than room temperature.
This is normal while the compressor works to transfer heat from inside the unit cabinet.

Problem CorrectionCause
Louder sound levels whenever Freezer/ refrigerator is on.
Louder sound levels when compressor comes on.
Popping or cracking sound when compressor comes on.
Bubbling or gurgling sound.
Vibrating or rattling noise.
Moisture forms on inside Freezer/refrigerator walls.
Modern Freezers have increased storage capacity and more stable temperatures. They require heavy duty compressors.
Freezer/refrigerator operates at higher pressures during the start of the ON cycle.
Metal parts undergo expansion and contraction, as in hot water pipes.
Refrigerant used to cool the unit is circulating throughout system.
Freezer/refrigerator is not level. It rocks on the floor when it is moved slightly.
Floor is uneven or weak.
Freezer/refrigerator is touching the wall.
Weather is hot and humid, which increases internal rate of frost build-up.
Door is slightly open.
This is normal. When the surrounding noise level is low, you might hear the compressor running while it cools the interior.
This is normal. Sound will level off or disappear as freezer/refrigerator continues to run.
This is normal. Sound will level off or disappear as freezer/refrigerator continues to run.
This is normal.
Level the freezer/refrigerator.
Ensure floor can adequately support unit. Level the unit by putting wood or metal shims under part of the unit

No electric current is reaching the freezer/ refrigerator.
Ice maker is not working
Open the door less often.
Clean interior with sponge, warm water, and baking soda. Replace air filter.
Cover the food tightly.
This condition can force the cabinet out of square and misalign the door. Level unit.
Ensure floor can adequately support unit. Level the unit by putting wood or metal shims under part of the unit.
Replace lamp or light bulb.
See Problem section “Freezer/refrigerator compressor does not run” on previous page.
