AIR HANDLER HOMEOWNER'S 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 in-
stalled 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.
MOTORS
Indoor and outdoor fan motors are permanently lubricated
and do not require additional oiling.
HIGH VOLTAGE
Disconnect ALL power before servicing or
installing this unit. Multiple power sources
may be present. Failure to do so may cause
property damage, personal injury or death.
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.
AIR HANDLER
WARNING
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.
To avoid the risk of equipment damage or fire, install the
same amperage breaker or fuse as you are replacing. If the
circuit breaker or fuse should open again within thirty days,
contact a qualified servicer to correct the problem. If you
repeatedly reset the breaker or replace the fuse without
having the problem corrected, you run the risk of severe
equipment damage.
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
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 op-
erating noise, that might be coming from the outdoor
unit. If you hear unusual noise(s) coming from the unit,
call a qualified servicer.
