OPERATING INSTRUCTIONS
NOTE: Thermostat styles vary. Some models may not include the AUTO mode
and others will have the AUTO in place of the HEAT and COOL. Others may
include all three. Please refer to the thermostat manufacturer’s User manual
for detailed programming instructions.
NOTE: Allow at least one hour for the room temperature to stabilize
before you make a second adjustment to the thermostat setting. After the
desired comfort level is established, make only small adjustments to the
thermostat setting to meet changing temperature conditions.
Cooling Operation
- Set the thermostat’s system mode to COOL or AUTO and change the fan mode to AUTO. See Figure 1,
- Set the temperature selector to the desired temperature level. The outdoor fan, compressor, and blower motor will all cycle on and off to maintain the indoor temperature at the desired cooling level.
Heating Operation
- Set the thermostat’s system mode to HEAT or AUTO and change the fan mode to AUTO. See Figure 1.
- Set the temperature selector to the desired temperature level. The compressor, outdoor fan, and blower motor will cycle on and off to maintain the indoor temperature at the desired heating level.
Operating the Indoor Blower Continuously
- 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.
- Set the thermostat fan mode to ON (Figure 1). The indoor blower starts immediately and will run continually until the fan mode is reset to AUTO.
- The continuous indoor blower operation can be obtained with the thermostat system mode set in any position, including OFF.
Turning the Heater OFF
Change the thermostat’s system mode to OFF and the fan mode to AUTO. See
Figure 1. NOTE: The system will not operate, regardless of the temperature
selector setting.
CAUTION
For optional A/C or H/P systems, always wait at least five minutes after the
system shuts off before restarting the system.
UNIT MAINTENANCE
WARNING
Shut off all electrical power to the unit before performing any maintenance or
service on the system. Failure to comply may result in personal injury or
death.
WARNING
This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and
knowledge unless they have been given supervision or instruction concerning
the use of the appliance by a person responsible for their safety. Children
should be supervised to ensure that they do not play with the appliance.
CAUTION
There are No user-serviceable parts inside the control panel. DO NOT OPEN.
NOTE: All servicing of this heating appliance other than the normal
maintenance described in this section must be done by authorized trained
service personnel. Do not attempt any servicing that requires the opening of
the control panels.
- Proper maintenance is most important to achieve the best performance from the appliance and should be performed frequently at the beginning of each heating season.
- Keep the area surrounding the unit clean. Keep the unit clear of obstructions.
WARNING
Never operate the furnace without a filter in place. Accumulating dust in the
return air can build up on internal components, resulting in loss of
efficiency, equipment damage, and possible fire.
- This electric furnace is supplied with a single air filter when shipped from the factory. It is recommended that the filter be cleaned or replaced monthly. Newly built or recently renovated homes may require more frequent changes until the construction dust has been minimized. Inspect filters frequently and replace them when necessary with filters of the same dimensional size.
- Filters designed to remove smaller particles such as pollen, may require additional maintenance.
Coil Filters
- If a cooling coil is installed on your unit, the furnace filter should not be used.
- If wire mesh coil filters are being used, they must be removed, washed and allowed to dry monthly. Once dry they must be re-installed to their original position.
- If a coil box is being used, the disposable filters should be replaced monthly.
Blower Compartment
Dirt and lint can create excessive loads on the motor resulting in higher-
than-normal operating temperatures and shortened service life. Wipe the
interior of the furnace cabinet clean. Clean all lint and dust from around the
furnace. It is recommended that the blower compartment be cleaned of dirt or
lint that may have accumulated in the compartment or on the blower and motor
as part of regular maintenance.
TROUBLESHOOTING
If the unit fails to operate, check the following:
- Check the thermostat setting. Make sure the system mode and temperature settings are correct.
- Check the electrical panel for tripped circuit breakers.
- Check the filters for dust accumulation.
- Check the outdoor unit and make sure it is clean and not covered with grass or leaves.
- If the items above don’t resolve your problems, then call your nearest service technician. Please specify the complete model and serial numbers shown on the furnace data label for all warranty services and when ordering replacement parts or optional equipment.
Refer to the replacement parts list provided by the manufacturer for part numbers.
