Safe Servicing Practices
Avoid personal injury and/or property damage by observing important Safe Servicing Practices.
Following are some limited examples of safe practices:
1. DO NOT attempt a product repair if you have any doubts as to your ability to complete the repair in a safe and satisfactory manner.
2. Always Use The Correct Replacement Parts as indicated in the parts documentation. Substitutions may defeat compliance with Safety Standards Set For Home Appliances.
3. Before servicing or moving an appliance:
• Remove power cord from the electrical outlet, trip circuit breaker to the OFF position, or remove fuse.
4. Never interfere with the proper operation of any safety device.
5. Use ONLY REPLACEMENT PARTS CATALOGED FOR THIS APPLIANCE. Substitutions may defeat compliance with
Safety Standards Set For Home Appliances.
6. GROUNDING: The standard color coding for safety ground wires is GREEN, or GREEN with YELLOW STRIPES.
Ground leads are not to be used as current carrying conductors. It is EXTREMELY important that the service technician reestablish all safety grounds prior to completion of service. Failure to do so will create a hazard.
7. Prior to returning the product to service, ensure that:
• All electrical connections are correct and secure.
• All electrical leads are properly dressed and secured away from sharp edges, high-temperature components, and moving parts.
• All non-insulated electrical terminals, connectors, heaters, etc. are adequately spaced away from all metal parts and panels.
• All safety grounds (both internal and external) are correctly and securely connected.
• All panels are properly and securely reassembled.

Section 1 Basic Information
How to Choose a Room Air Conditioner
Compared to large capacity central units, room air conditioners have several advantages. The initial cost of a room air conditioning unit is signifi cantly lower that the cost of central air. Because room air conditioners are designed for cooling small spaces, operating costs are reduced. And, room air conditioners can provide personalized temperature and humidity controls that central systems cannot.
Calculating Cooling Capacity
Cooling capacity is the critical factor in properly selecting a room air conditioner. Cooling capacity is measured in British Thermal Units (BTUs) and typical models will range in capacity from 5,000 BTUs to 28,500 BTUs. Choosing an undersized unit will overwork the unit and it will not cool properly. Choosing an oversized unit will cost more to buy and operate and it will not dehumidify properly. Your dealer can help you to calculate capacity. Be prepared to provide specifi c information on:
• Room dimensions
• A simple floor plan to show the location of doors and north-facing windows
• The number of people it will serve
• Sources of heat such as lamps, TV and appliances
• An explanation of what’s above the intended room
• Your insulation provisions
Cooling Capacity by Room Size
Measure the length and width of the area to be cooled. Multiply the length by the width to determine square footage or square meters. Locate the room size in the chart below to select the appropriate BTUs. Then use the product information to select the unit for your room.

Section 1 Basic Information
V ibration
Unit may vibrate and make noise because of poor wall or window construction or incorrect installation.
Pinging or Swishing
Droplets of water hitting condenser during normal operation may cause
“pinging or swishing” sounds.
Gurgle/Hiss
“Gurgling or hissing” noise may be heard due to refrigerant passing through evaporation during normal operation.
Cleaning
Clean your air conditioner occasionally to keep it looking new. Be sure to unplug the unit before cleaning to prevent shock or fi re hazards.
Air Filter Cleaning
The air fi lter should be checked at least once a month to see if cleaning is necessary. Trapped particles in the fi lter can build up and cause an accumulation of frost on the cooling coils.
1. Grasp the filter by the center and pull up and out.
2. Wash the filter using liquid dishwashing detergent and warm water. Rinse filter thoroughly. Gently shake excess water from the filter. Be sure filter is thoroughly dry before replacing.
3. Or, instead of washing you may vacuum the filter clean.
Cabinet Cleaning
1. Be sure to unplug the air conditioner to prevent shock or fire hazard. The cabinet and front may be dusted with an oil-free cloth or washed with a cloth dampened in a solution of warm water and mild liquid dishwashing detergent. Rinse thoroughly and wipe dry.
2. Never use harsh cleaners, wax or polish on the cabinet front.
3. Be sure to wring excess water from the cloth before wiping around the controls. Excess water in or around the controls may cause damage to the air conditioner.
4. Plug in air conditioner.
Winter Storage
If you plan to store the air conditioner for the winter, cover it with plastic or return it to the original carton.
NOTE: To prevent rust or electrical connections from being damaged, store air conditioner in an upright position and a dry place.

Installing the Unit in a Casement Window
NOTE
Open the window the maximum amount to allow for clearance of the cabinet. The crank handle should be removed to allow the platform to be fastened to the jamb. If the window cannot open far enough
(more than 15-1/2 inches) for the cabinet to clear the window, remove the window entirely by drilling out the rivets. Bolts can serve as the pivots in the future.
To avoid crank handle and window clearance problems, the unit can be installed in a stationary sash section.
However, the horizontal mullion and the 2 glass panels must be removed before installation.
1. Attach support brace to platform as shown. Use the adjustment bolt and hex flange nut to complete the assembly. Choose the slot and adjustment bolt hole locations that will create a 45 degree angle between the platform and the support brace. Try the assembly in the window to determine if the platform will rest properly, and allow the proper slope (3/16inch lower on outside). (See Figure 2-50)
NOTE
If you are planning to use a siding protection board on the outside of house, hold board in place when testing assembly in window.
2. Drill a 9/64-inch diameter pilot hole in the window jamb an equal distance from each side of the jamb, and 3/16-inch up from the window sill. If the hole coincides with the window lever slot in the jamb bottom, an additional hole will have to be drilled through the platform edge and the window jamb to
3. Peel off the protective backing from the track seal, and stick the seal to the window sill on the outside of the bottom jamb. (See Figure 2-51)
4. Screw the platform assembly to the window jamb through the pilot hole you drilled in Step 2. Use a #8 x 3/4-inch self-threading screw.
5. Adjust the platform assembly so that the rear of the air conditioner will be 3/16-inch lower than the front. This ensures proper water drainage from the air conditioner. (See Figure 2-53)

AIR CONDITIONER VOLTAGE LIMITS
Low voltage is a common cause of trouble in the operation of any room air conditioner. Improper voltage may cause one or more of the following problems:
1. Unit will not start.
2. Compressor motor cycling on motor protector.
3. Premature failure of motor protector.
4. Blown fuses.
5. Premature failure of compressor or fan motor.
6. Noticeable dimming of lights when air conditioner is
running.
7. Evaporator icing. Low voltage may reduce fan speed resulting in inadequate air flow over evaporator, thereby allowing it to ice up.
Low voltage can also be the direct result of inadequately wired circuits, extension cords, or loose fuses and connections to the power supply. Voltage may also be a general condition in the area (a responsibility of the power company).
All units will start and run on the minimum voltage stated in the chart to the left (Figure 5-1), and will perform satisfactorily if the voltage remains constant.
Low voltage caused by defective wiring will not remain constant under load.
To test for low voltage, use a reliable meter with sufficient capacity to measure the required voltage. Take measurements at the electric power entry point and at the electric outlet serving the air conditioner. Take readings with the unit off, while the unit is starting, and again while the unit is running. The lowest reading should not drop below the lowest value listed in the chart.

Repair or replace any malfunctioning line voltage component before testing or replacing the electronic control. DO NOT assume a service problem is directly caused by the electronic control system. A line voltage component
(including power cord and wiring) that has opened, shorted, grounded or otherwise malfunctioned, may have created a service problem.
HIGH VOLTAGE
High voltage can be equally troublesome, causing motors to overheat, cycle on their protectors, or break down electrically. This problem can only be solved by the power company.
ELECTRONIC CONTROL
This control is not repairable. If any component in the control is defective, the entire control must be replaced.

IMPORTANT
The purpose of this service manual is to give the service technician an understanding of the changes in refrigerants and sealed system service. Persons attempting to use this service manual to make repairs to sealed system refrigeration systems should have electrical training as well as training in sealed system repairs. The person making the repairs must know and understand all laws (Local and International) governing handling of all refrigerants. The technician must be trained in the use of recovery and recycling equipment. Electrolux Home Products, Inc. cannot be responsible, nor assume any liability, for injury or damage of any kind arising from the use of this manual.
NOTE
Electrolux does not permit the use of recovered refrigerant in the servicing of our products for in-warranty and outof-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.
IMPORTANT
Effective July 1, 1992, the United States clean air act governs the disposal of refrigerants such as R-22. 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.
IMPORTANT
Safety and CFC Certification
Complying with Section 608 Refrigerant Recycling Rule: http://www.epa.gov/ozone/title6/608/608fact.html#techcert
EPA has established a technician certification program for persons (“technicians”) who perform maintenance, service, repair, or disposal that could be reasonably expected to release refrigerants into the atmosphere.
The definition of “technician” specifically includes and excludes certain activities as follows:
Any person who performs maintenance, service, or repair that could reasonably be expected to release class I (CFC) or class II (HCFC) substances from appliances, into the atmosphere. Technician also means any person performing disposal of appliances, except for small appliances, MVACs, and MVAC-like appliances that, could be reasonably expected to release class I or class II refrigerants from appliances into the atmosphere.
Small appliance is defined as:
Any of the following products that are fully manufactured, charged, and hermetically sealed in a factory with five pounds or less of refrigerant: refrigerators and freezers designed for home use, room air conditioners (including window air conditioners and packaged terminal air conditioners), packaged terminal heat pumps, dehumidifiers, under-the-counter ice makers, vending machines, and drinking water coolers.
The Agency has developed four types of certification:
1. For servicing small appliances (Type I).
2. For servicing or disposing of high- or very high-pressure appliances, except small appliances and MVACs (Type II).
3. For servicing or disposing of low-pressure appliances (Type III).
4. For servicing all types of equipment (Universal).
Technicians are required to pass an EPA-approved test given by an EPA-approved certifying organization to become certified under the mandatory program. Section 608 Technician Certification credentials do not expire. Overview of
Issues on EPA Certification Test: http://www.epa.gov/ozone/title6/608/technicians/certoutl.html
R-22 requires training of installation and service personnel in the proper and safe handling of R-22.
Many equipment manufacturers are well aware of the concerns and safety issues of working with R-22 and other
HCFC refrigerants and are requiring installation and service professionals who purchase their R-22 systems to be
R-22 Certified.

Service Diagnostic Tips
A prime requisite on the initial contact is: Always allow the customer to explain the problem. Many times the trouble can be diagnosed more quickly, based on the customer’s explanation. Most of all, do not jump to conclusions until you have heard the full story and have evaluated the information obtained from the customer. Then proceed with your diagnosis.
Before starting a test procedure, connect the product service cord to the power source, through a wattmeter, combined with a voltmeter. Then make a visual inspection and operational check of the air conditioner to determine the following:
1. Is the product properly leveled?
2. Is the product located for proper dissipation of heat from the condenser? Check install location.
3. Feel condenser. With compressor in operation, condenser should be hot, with gradual reduction in temperature from entry to exit of condenser.
4. Is evaporator fan properly located on motor shaft?
5. Is the thermostat sensing element properly positioned?
6. Observe frost pattern on evaporator.
7. Check control setting.
For air-conditioners, check room size, temperature, amount of people, windows, and other factors that increase the load on the product. After this phase of diagnosis is completed, a thorough operational check should be made of the refrigeration system.
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.
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.
6-2
Section 6 Sealed System
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.
Soldering
1. All joints to be soldered must have a 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.
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.
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. Use a good grade of silver solder. A 45% silver solder is recommended. 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.
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 fl ame, 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 suffi cient 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.
When a hydraulic block occurs, the compressor is prevented from starting. This condition is known as locked rotor. Electric current continues to fl ow 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 the 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 specifi ed for the system.
6-3
Section 6 Sealed System
Basic Components
The basic components of an air conditioner are a compressor, condenser, evaporator and heat exchanger
(capillary tube and suction line).
Refrigerant Cycle
A typical sealed refrigeration system consists of a cooling coil (evaporator) located on the room side, a heat rejection coil (condenser) located outside, and an electric self-contained motor/compressor to circulate a refrigerant through the system and develop the necessary pressure differential to make the system work. Copper tubing, sized to carry the volume of refrigerant to be circulated, connects these components in a continuous loop, evaporator to compressor to condenser then back to the evaporator. The tube connecting the condenser to the evaporator also serves as a refrigerant fl ow control. This tube (restictor tube) has a very small inside diameter.
The combination of this small diameter and extra length of this tube restricts the fl ow of liquid refrigerant, maintaining the pressure differential necessary for the function of the refrigeration system. A cone shaped strainer is placed in the last pass of the condenser to prevent any foreign material from clogging the restrictor tube.
Room Air Conditioner Sealed System
Condenser
Condenser
Compressor
Evaporator
The operation of the refrigeration system involves three basic physical laws:
1. The physical state of a substance (solid, liquid or gas) is directly related to the heat contained in the substance.
2. A great amount of heat is required to change the state of a substance (solid to liquid, liquid to gas, and visa versa) with no change in its temperature.
3. The temperature at which a substance changes from liquid to gas and gas to liquid depends upon the pressure on the substance.
In operation, the compressor lowers the pressure on the liquid refrigerant in the evaporator to the point at which the refrigerant will change from a liquid to a gas at temperatures ranging between 35°F and 50°F. The heat required for this change of physical state is obtained from the room air circulated through the evaporator fi ns. Heat is absorbed by the refrigerant, not only from the air, but from moisture in the air as well. The air is cooled and the moisture condenses on the evaporator fi ns.
As the refrigerant liquid continues to vaporize, the pressure in the evaporator tends to rise. However, the compressor removes vapor at rate which maintains the desired pressure and temperature in the evaporator.
The compressor discharges the refrigerant gas into the condenser where the pressure builds up against the restrictor tube. As the pressure of the gas increases, so does its temperature. When the temperature of the gas in the condenser exceeds the temperature of the air passing through the condenser, heat is transferred from the gas to the outside air. This loss of heat causes the refrigerant gas to condense back to a liquid.
The small diameter restrictor tube between the condenser and the evaporator maintains the pressure difference created by the compressor, and meters the liquid refrigerant back to the evaporator. The refrigerant cycle is now complete and will continue until the compressor is turned off by the thermostat.

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 filter-drier 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.
6-5
Section 6 Sealed System
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 the next page
“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 on page 6-9, “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.

Section 6 Sealed System
Installing a New Compressor
Replacement of the compressor must be done in a continuous sequence so the system is exposed to the atmosphere no longer than necessary.
All replacement compressors are shipped with rubber plugs in the suction and discharge tubes and contain the correct oil charge and a holding charge of inert gas.
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.
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.
A process tube is connected onto the high-side process tube where the line splits into capillary tubes. The other process tube is connected to the tubing prior to entering the accumulator.
4. Remove leads from compressor motor terminals.
5. Remove mounting nuts and washers.
6. 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.
7. 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.
8. Install new compressor in exact same manner as original compressor.
9. 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 joints.
Clean and mark area where tubing should be cut.
Cut tubing with tubing cutter. Work quickly to avoid letting moisture and air into system.
10. Solder all connections according to soldering
procedure.
NOTE
If low-side process tube is too short, silver solder four inch piece of tubing onto process tube at this time.
On R-22 systems, compressor must NOT be left open to atmosphere for more than 10 minutes to prevent moisture contamination of oil.

Final Leak Test
1. With the refrigerator turned OFF leak test all low-side system components.
2. Turn unit ON and run until the condenser is warm.
Leak test the high-side system components.
Air Conditioner Air Temperatures
Temperatures are affected by frost accumulation on the evaporator, service load, ambient temperature, percent of relative humidity, thermostat calibration (cut-in and cut-out), and by compressor efficiency.
Line Voltage
It is essential to know the line voltage at the product.
A voltage reading should be taken at the instant the compressor starts, and also while the compressor is running. Line voltage fluctuation should not exceed 10% plus or minus, from nominal rating. Low voltage will cause overheating of the compressor motor windings, resulting in compressor cycling on thermal overload, or the compressor may fail to start. Inadequate line wire size, and overloaded lines, are common reasons for low voltage at the product.

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.

3. 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, but removing the line tap valve installed to remove the refrigerant. Install the correct sized process tube adapter.
4. Attach refrigeration service gauge manifold to system in following order: a. Low-side (compound gauge) hose to suction side process tube adapter.
b. High-side (pressure gauge) hose to vacuum pump.
c. Center port manifold hose after hand shut-off valve to charging cylinder.
Installing Evacuation and Recharging
Equipment For Rotary Compressors
1. Disconnect electrical supply to unit.
2. Attach an approved self tapping line tap valve to the process tube. Connect refrigerant recovery system to tap valve. Turn on recovery system, open the line tap valve, and allow refrigerant to flow into an approved tank.
3. 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, but removing the line tap valve installed to remove the refrigerant. Install the correct sized process tube adapter.
4. Attach refrigeration service gauge manifold to system in following order: a. Low-side (compound gauge) hose to high side process tube adapter.
b. High-side (pressure gauge) hose to vacuum pump.
c. Center port manifold hose after hand shut-off valve to charging cylinder.
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.
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.
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.

Section 6 Sealed System
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. If a filter-drier has been added to the system, add .78 ounces of refrigerant to allow for the additional volume of the sealed system.
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 l liquid.
Preparing The Charging Cylinder:
A. Recharging refrigerant tank must have at least eight (8) ounces more refrigerant than required to recharge.
B. Plug in cylinder heater and bring pressure up 30 pounds above gauge pressure at ambient temperature. Do not exceed maximum temperatures.
To Charge System:
WARNING
Do not use an external heat source on cylinder or exceed maximum gauge pressure on charging cylinder.
CAUTION
Maintain, but do not exceed, this 30 pound increase in gauge pressure during system charging.
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 AC unit to its highest (coldest) setting.
Run unit 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. Remove line tap valve. Solder process tube closed.
10. Turn off AC unit. After a few minutes check process tube for leaks.

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-22 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-22 systems.
For other brands of vacuum pumps, check with the manufacturer for restrictions and guidelines when using with R-22.
If you use a vacuum pump with mineral oil to evacuate an R-22 system, it is ABSOLUTELY
ESSENTIAL to have a shut-off valve between pump and your manifold gauge set. The hand valve must be closed during all times when vacuum pump is not operating. This will prevent migration of mineral oil vapor into R-22 oil systems. If the vacuum pump
should stop during evacuation for any reason, the hand pump shut-off valve must be closed immediately.

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.
