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.

Features & Benefits
Electronic Controls
Set the room temperature at the preferred comfort level.
Electronic controls and convenient temperature readout
ensures the unit is set at the precise comfort level you
require. All electronic models maintain the temperature to
be within 2 degrees of the set temperature.
Anti-Microbial Filter & Clean Air Purification
Enjoy a cool, comfortable room with air cleaned by a
patented clean air anti-microbial filter, which reduces bacteria, odors and other particles. The clean air purification
also improves air quality above standard filter methods
resulting in relief for allergy and respiratory ailment
sufferers. Look for models with the clean air ionizer for
improved air filtration performance.
Multi-Speed Fan
Cool down a room at the rate you decide. Auto Temp
adjusts the fan speed up or down until the room reaches
the desired temperature. A multi-speed fan allows you to
choose from 3 speeds.
Sleep Mode
Provides worry-free operation and energy savings while
you sleep. 30 minutes after you set this mode, temperature increases two degrees. After 30 minutes more,
it goes up another two, then holds for 7 hours before
returning to the original temperature.
Energy Saver
Energy Saver mode cycles the fan and compressor until
the room temperature increases above the set temperature, then returns to normal operation until the set
temperature in the room is again reached.
Full Function Remote
The patented Temperature-Sensing Remote offers an
added level of comfort and control by offering temperature monitoring by the remote control itself or at the air
conditioner. Take room temperature up or down a notch,
right from your favorite armchair. This convenient remote
offers precise temperature selection from a distance.
Look for models with Remote Thermostat that allow the
unit to sense temperature where it is important,
where you are at with the remote control.

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 significantly 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
specific 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.

NOTE
When cooling rooms with uninsulated ceilings, great rooms, or southern or western sun exposures – step up to the
next BTU size or consult your sales professional.

operation may cause
“pinging or swishing”
sounds.
Cleaning
Clean your air conditioner occasionally to keep it looking new. Be sure to unplug the unit before cleaning to prevent
shock or fire hazards.
Air Filter Cleaning
The air filter should be checked at least once a month to see if cleaning is necessary. Trapped particles in the filter can
build up and cause an accumulation of frost on the cooling coils.

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

1. Cut or build a wall opening in the masonry wall
similar to the frame construction (refer to Thru-theWall Installation for a wall thickness greater than
8-½ inches).
2. Secure cabinet in place using masonry nails, or the
correct masonry anchor screws. (Another way to

shown in Prepare Wall illustrations - but make it
double framed on either side, and install between
masonry wall opening and cabinet. Frame must be
securely anchored to masonry wall opening) This
way gives very good louver clearance on either side
of cabinet.
3. Install a linted to support masonry wall above
cabinet. Existing holes in cabinet can be used and/
or additional holes can be drilled to fasten cabinet at
various positions. Be sure that side louver clearance
is in accordance with Step 1 above.
4. Install exterior cabinet support brackets as shown in

Installing the Unit in a Casement Window
Platform Assembly
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)

Section 5 Troubleshooting and Testing
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.

CAUTION
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.

Section 6 Sealed System
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.

Section 6 Sealed System
Safety Warnings
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.
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.
When a hydraulic block occurs, the compressor is
prevented 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 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
specified 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 flow 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 flow 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.

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 fins. 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 fins.
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.
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.
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 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.
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.

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.
DO NOT OPERATE RECIPROCATING
COMPRESSORS WHEN CHARGING LIQUID
REFRIGERANT INTO SYSTEM THROUGH ITS
PROCESS TUBE.
Follow the numbered sequence for all products:
1. Disconnect electrical supply to unit.
2. Remove all components necessary to access the
compressor assembly in the unit.
3. 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.
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.
11. Install filter-drier between condenser outlet and the
capillary tube connection.
12. Evacuate and charge system using recommended
procedure described under Evacuating and
Recharging.
13. Reconnect compressor terminal leads in accordance
with unit wiring diagram and reassemble unit.

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.
Section 6 Sealed System
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.
To Use Refrigerant To Flush The System:
CAUTION

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.

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.
6-12
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.
Section 6 Sealed System
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.
