The successful development of hermetically sealed refrigera-
tion compressors has completely sealed the compressor's
moving parts and electric motor inside a common housing,
minimizing refrigerant leaks and the hazards sometimes
associated with moving belts, pulleys or couplings.
Fundamental to the design of hermetic compressors is a
method whereby electrical current is transmitted to the
compressor motor through terminal conductors which pass
through the compressor housing wall. These terminals are
sealed in a dielectric material which insulates them from the
housing and maintains the pressure tight integrity of the
hermetic compressor. The terminals and their dielectric
embedment are strongly constructed, but are vulnerable to
careless compressor installation or maintenance proce-
dures and equally vulnerable to internal electrical short
circuits caused by excessive system contaminants.
WARNING
System contaminants, improper service procedure
and/or physical abuse affecting hermetic compressor
electrical terminals may cause dangerous system
venting.
WARNING
To avoid possible injury, explosion or death, practice
safe handling of refrigerants.
SAFE REFRIGERANT HANDLING
While these items will not cover every conceivable situation, they should serve as a useful guide.
To avoid possible explosion, use only returnable (not
disposable) service cylinders when removing refrig-
erant from a system.
• Ensure the cylinder is free of damage which could
lead to a leak or explosion.
• Ensure the hydrostatic test date does not exceed
5 years.
• Ensure the pressure rating meets or exceeds 400
lbs.
When in doubt, do not use cylinder.
WARNING
In either of these instances, an electrical short between the
terminal and the compressor housing may result in the loss
of integrity between the terminal and its dielectric embed-
ment. This loss may cause the terminals to be expelled,
thereby venting the vaporous and liquid contents of the
compressor housing and system.
A venting compressor terminal normally presents no danger
to anyone, providing the terminal protective cover is properly
in place.
If, however, the terminal protective cover is not properly in
place, a venting terminal may discharge a combination of
(a) hot lubricating oil and refrigerant
(b) flammable mixture (if system is contaminated
with air)
in a stream of spray which may be dangerous to anyone in the
vicinity. Death or serious bodily injury could occur.
Under no circumstances is a hermetic compressor to be
electrically energized and/or operated without having the
terminal protective cover properly in place.
IMPORTANT INFORMATION
Refrigerants are heavier than air. They can "push out"
the oxygen in your lungs or in any enclosed space.To
avoid possible difficulty in breathing or death:
• Never purge refrigerant into an enclosed room or
space. By law, all refrigerants must be reclaimed.
• If an indoor leak is suspected, thoroughly ventilate
the area before beginning work.
• Liquid refrigerant can be very cold. To avoid possible
frostbite or blindness, avoid contact with refrigerant
and wear gloves and goggles. If liquid refrigerant
does contact your skin or eyes, seek medical help
immediately.
• Always follow EPA regulations. Never burn refrig-
erant, as poisonous gas will be produced.

IMPORTANT INFORMATION
Please read and follow the important notes below.
Installation:
1. Always use the correct size circuit breaker and fuse.
Circuit breakers should be installed on a dedicated
circuit.
2. Properly ground the unit.
3. Do NOT use extension cords.
4. Ensure that the unit is mounted on a stable instal-
lation stand. Check periodically for signs of deterio-
ration.
5. Running the unit for long periods of time during high
humidity or with windows/doors open may cause
condensation on furnishings.
6. The power cable should not be stretched and noth-
ing should sit on it. Always turn the unit off before
plugging or unplugging the power cable.
7. Make sure proper ventilation of conditioned space is
provided.
8. Protect unit before arrival of inclement weather.
9. Do not open the inlet grill during operation of the unit.
10. Do not touch the electrostatic filter if unit is equipped
with one.
11. If smoke or unusual noises emit from the unit,
immediately turn off the unit and disconnect ALL
power. (See warning above.)
12. Do not allow water to enter the unit. In the instance
that the unit is soaked or submerged, contact an
authorized servicer.
13. When the unit is not used for a long period of time,
disconnect ALL power to the unit.
14. Place the outdoor unit in a location away from high
traffic areas to prevent tripping or damage to the unit.
Do not place objects on the unit.
1. Always check for refrigerant leakage after installa-
tion or repair of the product.
2. Drain hose must be installed properly so water will
drain away from the unit.
3. Installing the unit in an unlevel position may cause
vibration or water leakage.
4. Install the outdoor unit away from vegetation as the
hot air may cause damage to vegetation in close
proximity.
5. To avoid personal injury, always use two people to lift
or transport the unit.
6. Unit should not be installed where it may be exposed
directly to sea coast conditions (sea wind or salt
spray).
Hazards or unsafe practices result in
property damage, product damage, personal injury
or death.
may
Operation:
1. Do not block the inlet or outlet of airflow.
2. Do not use harsh detergents, solvents, etc., to clean the
unit. A soft cloth is recommended.
3. Use caution when removing the air filter, as there may be
sharp, metal edges.
4. Clean the filter every two weeks or more often, if neces-
sary and be sure to seat the filter securely.
5. Keep hands and foreign objects away from the air outlets
while the unit is in operation.
