General Information - Nordyne JS4BD-KA Series User's Information And Installation Instructions Manual

The indoor blower will start immediately, and
will run continually until the fan switch is reset
to AUTO.
The continuous indoor blower operation can be
obtained with the thermostat system switch set
in any position, including OFF.
The continuous indoor blower operation is
typically used to circulate the indoor air to
equalize a temperature unbalance due to a sun
load, cooking, or fi replace operation.
To Maintain Your Air Conditioner —
CAUTION:
Be certain the electrical power to
the outdoor unit and the furnace/
air handler is disconnected before
doing the following recommended
maintenance.
1. Regularly:
a. Clean or replace the indoor air fi lter at the
start of each heating and cooling season,
and when an accumulation of dust and dirt
is visible on the air fi lter.
b. Remove any leaves and grass clippings
from the coil in the outdoor unit, being
careful not to damage the aluminum fi ns.
c. Check for any obstruction, such as twigs,
sticks, etc.
2. Before Each Cooling Season:
If the furnace/air handler blower motor and
the outdoor unit fan motor(s) have oil tubes
at the motor bearings, apply 10 drops of
SAE No. 20 motor oil to each oil tube.
CAUTION:
Do not over-oil, or oil motors not
factory-equipped with oil tubes. The
compressor is hermetically "sealed"
and does not require lubrication.
3. Before Calling a Service Technician, Be
Certain:
a. The unit thermostat is properly set
— see "To Operate Your Air Conditioner for
Cooling" and "To Operate Your Furnace for
Heating."
b. The unit disconnect fuses are in good
condition, and the electrical power to the
unit is turned on.
