6.  Inspect drain holes in coil compartment base and 

clean if necessary.

NOTE: 

If  insufficient  cooling  occurs,  the  unit  should  be 

gauged and refrigerant charge should be checked.

Outdoor Coil

Clean  and  inspect  outdoor  coil  (may  be  flushed  with  a 

water hose). Ensure power is off before cleaning.

NOTE: 

It  may  be  necessary  to  flush  the  outdoor  coil 

more frequently if it is exposed to substances which are 

corrosive or which block airflow across the coil (e.g., pet 

urine, cottonwood seeds, fertilizers, fluids 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 filters.

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.

Motor Nameplate:_________ Actual:__________.

Indoor Coil

1.  Clean coil if necessary.

2.  Check connecting lines, joints and coil for evidence of 

oil leaks.

3.  Check condensate line and clean if necessary.
