Some fan motors are provided with
lubrication ports. Inspect your indoor
and outdoor units to determine
whether or not lubrication ports are
provided.

The fan motor is shipped with an oil
supply which will last for several years
under normal operating conditions.
After this time, each motor bearing
should be oiled with 10-15 drops
(approximately 1/4 teaspoon) of SAE
20 non-detergent electric motor oil or
automobile oil. DO NOT use definite
purpose oils such as sewing machine,
cleaning, rust preventative, cutting,
household, etc.

Inspect the air filter(s) at least once a
month. If they are dirty, wash reusable
filters with a mild detergent per manu-
facturer's recommendations. Replace
disposable filters with new filters.

Install the clean filters with air flow"
arrow in the same direction as the air
flow in your duct. Filters should be
clean to assure maximum efficiency
and adequate air circulation. Drapes,
furniture or other obstructions blocking
your supply and return air grilles will
also decrease efficiency.

If you wish to maintain the finish of the
outdoor unit, it can be polished with car
wax. It is recommended the unit be
cleaned with soap and water prior to
waxing.

The minimum clearances shown below
must be maintained should any patio
or yard improvements be done around
the outdoor unit.

1.

Switch thermostat to OFF position.

2.

Do not switch to cooling or auto 
until electrical power has been 
reestablished for 8 hours if the 
power was off more than 8 hours.

There are a few instances where you
can avoid unnecessary service calls.
(See Troubleshooting Guide above).
Some models provide fault codes. The
flashing light on the system thermostat
is capable of providing you with time
and money saving information. The
fault code numbers listed can be han-
dled by taking the corrective action
indicated. Call qualified service person
if displaying fault code numbers not
listed.

Replacement parts are available from
local contractor/dealers or the nearest
distribution center.

Special warranty packages are avail-
able through your contractor/dealer.
These packages reduce the potential
cost of service calls following the first
year of operation on your cooling or
heating/cooling system.
