BEFORE YOU CALL YOUR SERVICER
•
Check the thermostat to confirm that it is properly set.
•
Wait 15 minutes. Some devices in the outdoor unit or in
programmable thermostats will prevent compressor op-
eration for awhile, and then reset automatically. Also, some
power companies will install devices which shut off air con-
ditioners for several minutes on hot days. If you wait sev-
eral minutes, the unit may begin operation on its own.
•
Check the electrical panel for tripped circuit breakers or
failed fuses. Reset the circuit breakers or replace fuses as necessary.
•
Check the disconnect switch near the indoor furnace or blower to confirm that it is closed.
•
Check for obstructions on the outdoor unit . Confirm that it has not been covered on the sides or the top. Remove any obstruc-
tion that can be safely removed. If the unit is covered with dirt or debris, call a qualified servicer to clean it.
•
Check for blockage of the indoor air inlets and outlets. Confirm that they are open and have not been blocked by objects (rugs,
curtains or furniture).
•
Check the filter. If it is dirty, clean or replace it.
•
Listen for any unusual noise(s), other than normal operating noise, that might be coming from the outdoor unit. If you hear
unusual noise(s) coming from the unit, call a qualified servicer.

ROUTINE MAINTENANCE RECOMMENDATIONS
We strongly recommend a bi-annual maintenance checkup be performed before the heating and cooling seasons begin by a
qualified servicer
.
REPLACE OR CLEAN FILTER
IMPORTANT NOTE:
Never operate unit without a filter installed as dust and lint will build up on internal parts resulting in loss of
efficiency, equipment damage and possible fire.
An indoor air filter must be used with your comfort system. A properly maintained filter will keep the indoor coil of your comfort
system clean. A dirty coil could cause poor operation and/or severe equipment damage.
Your air filter or filters could be located in your furnace, in a blower unit, or in “filter grilles” in your ceiling or walls. The installer of your
air conditioner or heat pump can tell you where your filter(s) are, and how to clean or replace them.
Check your filter(s) at least once a month. When they are dirty, replace or clean as required. Disposable type filters should be replaced.
Reusable type filters may be cleaned.
You may want to ask your dealer about high efficiency filters. High efficiency filters are available in both electronic and non-electronic
types. These filters can do a better job of catching small airborne
particles.
MOTOR
S
Indoor and outdoor fan motors are permanently lubricated and
do not require additional oiling.
ALUMINUM INDOOR COIL CLEANING
(QUALIFIED SERVICER ONLY)
This unit is equipped with an aluminum tube evaporator coil. The safest way to clean the evaporator coil is to simply flush the coil with
water. This cleaning practice remains as the recommended cleaning method for both copper tube and aluminum tube residential
evaporator coils.
It has been determined that many coil cleaners and drain pan tablets contain corrosive chemicals that can be harmful to aluminum
tube and fin evaporator coils. Even a one-time application of these corrosive chemicals can cause premature aluminum evaporator coil
failure. Any cleaners that contain corrosive chemicals including, but not limited to, chlorine and hydroxides, should not be used.
An alternate cleaning method is to use one of the products listed in TP-109* to clean the coils. The cleaners listed are the only agents
deemed safe and approved for use to clean round tube aluminum coils. TP-109 is also available on the web site in Partner Link > Service
Toolkit.
NOTE: Ensure coils are rinsed well after use of any chemical cleaners.
