General Information - Nordyne DS5BD User's Information And Installation Instructions Manual

To Operate Your Furnace for
Heating —
1. Set the thermostat system switch to HEAT
or AUTO and the thermostat fan switch to
AUTO. (See Figure 1)
2. Set the thermostat temperature to the
desired temperature level using the
temperature selector. Please refer to
the separate user's manual for complete
thermostat programming instructions. The
furnace and indoor blower will cycle on and
off to maintain the indoor temperature at
the desired heating level.
To Shut Off Your Air Conditioner —
Set the thermostat system switch to OFF
and the thermostat fan switch to AUTO. (See
Figure 1)
The system will not operate, regardless of the
thermostat temperature setting.
To Operate the Indoor Blower
Continuously —
Set the thermostat fan switch to ON (See
Figure 1)
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 fireplace 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.
2
1. Regularly:
a. Clean or replace the indoor air filter at the
start of each heating and cooling season,
and when an accumulation of dust and dirt
is visible on the air filter.
b. Remove any leaves and grass clippings
from the coil in the outdoor unit, being
careful not to damage the aluminum fins.
c. Check for any obstruction, such as twigs,
sticks, etc.
d. Certain models have external panels
fabricated from a premium grade of
stainless steel designed to inhibit cor-
rosion. For such units, if the unit is
located in a coastal region or other area
subjected to high concentrations of salt,
then the unit should be hosed off after
storms and monthly otherwise to maintain
its new appearance.
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.
