INDOOR HEAT PUMP UNIT,
BLOWER/COIL UNIT,
ELECTRIC WARM AIR FURNACE
The indoor unit to which these instructions apply is versatile, and your installing contractor may have applied it
with an outdoor heat pump section, a summer electric
cooling unit, or as a heating only unit.
Please become familiar with the provisions of the limited
warranty applicable to this unit. We suggest you record
on your Limited Warranty the complete model and serial
number and date of installation of this new indoor unit.
The model number and serial number are listed on the
rating plate, located either on the inner control box panel
or on the outer coil door panel. This information may be
helpful if a replacement part is required at a later date.
Except for the need to clean or change the air filters,
your unit will require little service. Therefore, these
instructions include only a few suggestions relating to
the use and care of this unit, but you should become
familiar with these pointers.
WARNING: DO NOT REMOVE SERVICE ACCESS
PANELS AND ATTEMPT UNIT SERVICE WITHOUT
FIRST OPENING ALL POWER DISCONNECTS.
BLOWER MOTOR
The blower motor sleeve bearings are prelubricated by
the motor manufacturer and may not require attention for
an indefinite period of time. However, our recommendations are as follows:
A. Motors without oiling ports —
Relubricated and sealed. No further lubrication should
be required, but in case of bearing problems, the
blower and the motor end belts can be disassembled
and the bearings relubricated by a qualified service
person.
CM 1101
B. Motors with oiling ports —
Add from 10 to 20 drops of Electric Motor Oil or an SE
grade of nondetergent SAE-10 or 20 motor oil to each
bearing every two years for somewhat continuous
duty, or at least every five years for light duty. Take
care not to over oil, because excessive lubrication
can damage the motor.
In any event, clean motor periodically to prevent the possibility of overheating due to an accumulation of dust and
dirt on the windings or on the motor exterior. And, as
suggested elsewhere in these instructions, the air filters
should be kept clean because dirty filters can restrict airflow and the motor depends upon sufficient air flowing
across and through it to keep from overheating.
FILTER MAINTENANCE
Check filter every sixty (60) days of operation under normal use and, if required, clean or replace. Replacement
filters should be the same size, or larger, and the same
type as originally supplied. If these filters are a permanent type they may be cleaned in warm soapy water and
replaced. The unit must not run without a filter, nor with a
dirty filter for a long period of time.
If system is equipped with electronic air cleaner instead
of conventional type air filters, consult the air cleaner
maintenance instruction.
INDOOR COIL (if applicable)
Check periodically and clean if necessary with warm
water and mild detergent.
