6. Inspect drain holes in coil compartment base and
clean if necessary.
NOTE: If insufcient cooling occurs, the unit should be
gauged and refrigerant charge should be checked.
Outdoor Coil
Clean and inspect outdoor coil (may be ushed with a
water hose). Ensure power is off before cleaning.
NOTE: It may be necessary to ush the outdoor coil
more frequently if it is exposed to substances which are
corrosive or which block airow across the coil (e.g., pet
urine, cottonwood seeds, fertilizers, uids that may contain
high levels of corrosive chemicals such as salts)
Sea Coast — Moist air in ocean locations can carry salt,
which is corrosive to most metal. Units that are located near
the ocean require frequent inspections and maintenance.
These inspections will determine the necessary need
to wash the unit including the outdoor coil. Consult your
installing contractor for proper intervals/procedures for
your geographic area or service contract.
Indoor Unit
1. Clean or change lters.
2. Some blower motors are pre-lubricated and
permanently sealed. No more lubrication is needed.
3. Adjust blower speed for cooling. Measure the pressure
drop over the coil to determine the correct blower
CFM. Refer to the unit information service manual for
pressure drop tables and procedure.
4. Belt Drive Blowers - Check belt for wear and proper
tension.
5. Check all wiring for loose connections.
6. Check for correct voltage at unit. (blower operating)
7. Check amp draw on blower motor.
