MOTOR LUBRICATION AND MAINTENANCE
The circulating air blower is equipped with bearings that are permanently lubricated by the motor
manufacturer and require no lubrication. At the time of the monthly filter inspection clean the exte-
rior of the circulating air motor, especially around the perimeter air holes to prevent the possibility
of overheating due to an accumulation of dust or dirt on the windings and motor casing. As sug-
gested elsewhere in these instructions, the air filters must be kept clean. Dirty filters will restrict
the air flow over the motor windings and possibly cause an overheating condition.
• The venter motor bearings are prelubricated by the motor manufacturer & require no attention.
SERVICE INSTRUCTIONS
DO keep the circulating air filters clean. The heating system will operate more efficiently and eco-
nomically.
DO arrange drapes & furniture so that the supply air registers & return air grilles are unobstructed.
DO close doors and windows. This will reduce the heat load on the system.
DO avoid excessive use of bathroom and kitchen exhaust fans.
DO NOT allow heat generated by televisions, lamps, direct sunlight, etc. to influence the thermo-
stat operation.
DO NOT allow combustible materials to accumulate within (3) feet of the furnace.
DO NOT use the furnace room as a storage area.
DO NOT store gasoline or other flammable liquids or vapors in the vicinity of the furnace.
SEQUENCE OF OPERATION
This appliance is controlled by the room thermostat. Within this section the term lockout is refer-
enced. This lockout is a “soft” lockout, which will re-set after one hour. It is the obligation of the in-
staller to educate the user on the proper use of the thermostat and the sequence of operation in
both the heating and cooling modes. It is also important that any repair or service be performed by
a QUALIFIED service person, not by the user.
Wrap the “R” leg around a clip-on
amp meter 10 times.
Energize the furnace in the
heat mode. Record the reading.
Divide this reading by
10. Set the heat anticipator
on the thermostat to match
this reading.
EXAMPLE:
If the reading on the amp meter is
“4”, divide this by 10.
The anticipator setting will be .4
amps.
