Residential Air Conditioners and Heat Pumps Using R-22 and Puron® Refrigerant: Application Guideline and Service Manual

CARE AND MAINTENANCE

To assure high performance and minimize possible equipment
malfunction, it is essential that maintenance be performed periodically
on this equipment. The frequency with which maintenance is performed
is dependent on such factors as hours of operation, geographic location,
and local environmental conditions.
WARNING
!
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or death.
Disconnect all electrical power to unit before performing any
maintenance or service on outdoor unit. Remember to disconnect
power supply to air handler as this unit supplies low-voltage power to
the outdoor unit.
The minimum maintenance that should be performed on this equipment
is as follows:
1. Check outdoor coil for cleanliness each heating and cooling season
and clean as necessary.
2. Check fan motor and blade for cleanliness each month during
cooling season and clean as necessary.
3. Check electrical connections for tightness and controls for proper
operation each cooling season and service as necessary.
CAUTION
!
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or
improper operation.
Because of possible damage to the equipment or personal injury,
maintenance should be performed by qualified personnel only.

Desert and Seacoast Locations

Special consideration must be given to installation and maintenance of
condensing units installed in coastal or desert locations. This is because
salt and alkali content of sand adheres to aluminum fins of coil and can
cause premature coil failure due to corrosion.
Preventive measures can be taken during installations, such as:
1. Locate unit on side of structure opposite prevailing winds.
2. Elevate unit to height where drifting sand cannot pile up against
coil. Mounting feet, 4 in. high, are available as accessories and can
be used to elevate unit.
3. Addition of coastal filter (See Product Data for accessory listing).
Maintenance in desert and seacoast locations:
1. Frequent inspection of coil and basepan especially after storms
and/or high winds.
2. Clean coil by flushing out sand from between coil fins and out of
basepan as frequently as inspection determines necessary.
3. In off season, cover with covering that allows air to circulate
through but prevents sand from sifting in (such as canvas material).
Do not use plastic as plastic will hold moisture possibly causing
corrosion.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

Cleaning Coil

1. Remove top cover. (See Remove Top Cover in Cabinet section of
this manual.)
2. Remove coil grilles or louvers (as applicable) to gain full access to
coils for cleaning.

UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or
improper operation.
Coil fin damage can result in higher operating costs or compressor
damage. Do not use flame, high-pressure water, steam, volatile or
corrosive cleaners on fins or tubing.
3. Clean coil using vacuum cleaner and its crevice tool. Move crevice
tool vertically, close to area being cleaned, making sure tool
touches only dirt on fins and not fins. to prevent fin damage, do not
scrub fins with tool or move tool horizontally against fins.
4. If oil deposits are present, spray coil with ordinary household
detergent. Wait 10 minutes, and proceed to next step.
5. Using garden hose, spray coil vertically downward with constant
stream of water at moderate pressure. Keep nozzle at a 15- to 20_
angle, about 3 in. from coil face and 18 in. from tube. Spray so
debris is washed out of coil and basepan.
6. Reinstall top cover and position blade.
7. Reconnect electrical power and check for proper operation.

Cleaning Outdoor Fan Motor and Blade

1. Remove fan motor and blade. Be careful not to bend or dent fan
blade.
2. Clean motor and blade with soft brush or cloth. Be careful not to
disturb balance weights on fan blade.
3. Check fan blade setscrew for tightness.
4. Reinstall fan motor and blade to top cover and check for alignment.
5. Reinstall top cover and position blade.
6. Reconnect electrical power and check for proper operation.
