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.
COMPRESSOR
The compressor motor is hermetically sealed and does not require addi-
tional oiling.
MOTORS
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 cooling coils.
An alternate cleaning method is to use one of the products listed below to clean the coils. The cleaners listed below are the only agents
deemed safe and approved for use to clean round tube aluminum coils.

NOTE: Ensure coils are rinsed well after use of any chemical cleaners.
CLEAN OUTSIDE COIL (QUALIFIED SERVICER ONLY)
Air must be able to flow through the outdoor unit of your comfort system.
Do not construct a fence near the unit or build a deck or patio over the
unit without first discussing your plans with your dealer or other quali-
fied servicer. Restricted airflow could lead to poor operation and/or se-
vere equipment damage.
Likewise, it is important to keep the outdoor coil clean. Dirt, leaves, or
debris could also restrict the airflow. If cleaning of the outdoor coil be-
comes necessary, hire a qualified servicer. Inexperienced people could
easily puncture the tubing in the coil. Even a small hole in the tubing
could eventually cause a large loss of refrigerant. Loss of refrigerant can
cause poor operation and/or severe equipment damage.
Do not use a condensing unit cover to “protect” the outdoor unit during
the winter, unless you first discuss it with your dealer. Any cover used must include “breathable” fabric to avoid moisture buildup.
BEFORE CALLING 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 operation for awhile, and
then reset automatically. Also, some power companies will install devices which shut off air conditioners for several minutes on hot
days. If you wait several 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 obstruction 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.
