ABOUT THE COOLING UNIT
The single packaged electric cooling unit is a high efficient self
contained appliance that will cool your home and provide energy
saving comfort. Additional features and benefits of the cooling include:
• Indoor and outdoor coils are designed to optimize heat transfer,
minimize size and cost, and increase durability and reliability.
• Environmentally friendly R-410A Refrigerant.
OPERATING INSTRUCTIONS
Thermostat styles vary. Some models may not include an AUTO
heat/cool changeover mode and others will have the AUTO heat/
cool changeover in addition to HEAT & COOL. Please refer to the
thermostat’s User manual for detailed programming instructions.
The thermostat should be mounted about 5 feet above the floor on
an inside wall and not on an outside wall or other location where its
operation may be adversely affected by radiant heat from fireplaces,
sunlight, or lighting fixtures, and convective heat from warm air
registers or electrical appliances.
Cooling Operation
1. Set the thermostat system mode to COOL and the thermostat
fan mode to AUTO. See Figure 1.
2. Set the thermostat temperature selector to the desired temperature
level. The outdoor fan, compressor, and indoor blower will all
cycle on and off to maintain the indoor temperature at the desired
cooling level.
NOTE: If the temperature level is re-adjusted, or the system mode
is reset, the fan and compressor in the outdoor unit may not start
immediately. There may be a protective timer circuit in the thermostat
which holds the compressor and the outdoor fan off for approximately
5 minutes following a previous operation or the interruption of the
main electrical power.
Heating Operation - Optional Electric Heat
1. Set the thermostat system mode to Heat and the thermostat fan
mode to AUTO. See Figure 1.
2. Set the thermostat temperature selector to the desired
temperature level. The indoor blower and electric heat module
will cycle on and off to maintain the indoor temperature at the
desired heating level.
System Shutdown
Set the thermostat system mode to OFF and the thermostat fan
mode to AUTO. See Figure 1.
NOTE: The system will not operate,
regardless of the thermostat temperature selector’s setting.
Operating the Indoor Blower Continuously
Set the thermostat fan mode to ON (or CONT on some thermostat
models). See Figure 1.
The indoor blower will start 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.
The continuous indoor blower operation is typically used to circulate
the indoor air to equalize a temperature imbalance due to a solar
load, cooking, or fireplace operation.
