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 additional oiling.
Motors
Indoor and outdoor fan motors are permanently lubricated
and do not require additional oiling.
Clean Outside Coil (Qualified Servicer Only)
WARNING
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.
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 qualified servicer.
Restricted airflow could lead to poor operation and/or
severe 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 becomes 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.
CAUTION
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.
• 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.
