Cooling; Fan Only; Start-Up, Adjustments, And Checks; Heating Start-Up - Whirlpool WGGE43 Installation Instructions Manual

Cooling

1. Thermostat calls for cooling. The compressor and outdoor
fan are energized.
2. Approximately 7 seconds later, the indoor fan starts.
3. The unit will deliver cooling to the conditioned space until the
thermostat is satisfied.
4. The compressor and outdoor fan will be de-energized when
the thermostat opens.
5. The indoor fan continues to run for approximately 60 seconds
after the thermostat is satisfied. This allows additional cooling
from the indoor coil to be transferred to the conditioned
space. Then, the indoor fan stops.
NOTE: A 180-second anti-short cycle is integral to the control
and prevents recycling of the compressor.

Fan Only

1. Thermostat calls for Fan Only by energizing G.
2. Approximately 7 seconds later, the indoor fan starts.
3. The indoor fan continues to run for approximately 60 seconds
after G is de-energized.
START-UP, ADJUSTMENTS,
AND CHECKS

Heating Start-Up

This unit is equipped with an electronic ignition device to
automatically light the main burners. It also has a power vent
blower to exhaust combustion products.
On new installations, or if a major component has been replaced,
the operation of the unit must be checked.
Check unit operation as outlined in the following instructions. If
any sparking, odors or unusual sounds are encountered, shut off
electrical power and recheck for wiring errors or obstructions in
or near the blower motors. Duct covers must be removed before
operating unit.
Heat Anticipator Setting
Set the heat anticipator on the room thermostat to 0.4 amps to
obtain the proper number of heating cycles per hour and to
prevent the room temperature from overshooting the room
thermostat setting.
Rollout Protection Control
The rollout protection device opens, cutting power to the gas
control valve, if the flames from the burners are not properly
drawn into the heat exchanger. The rollout protection device is
located on the burner bracket. The reason for elevated
temperatures at the control should be determined and repaired
prior to resetting this manual reset control.
WARNING
To avoid property damage, personal injury or death due
to fire or explosion, a qualified servicer must investigate
the reason for the rollout protection device to open
before manually resetting the rollout protection device.

Secondary Limit Control
The secondary limit control is located on the top of the blower
scroll assembly. This control opens when elevated temperatures
are sensed. Elevated temperatures at the control are normally
caused by blower failure. The reason for the opening should be
determined and repaired prior to resetting.
If the power to the unit is interrupted during the heating cycle, it
may cause the secondary limit control to trip. Once the blower
compartment temperature drops below the limit reset
temperature, the limit will automatically reset.

Pre-Operation Checks

1. Close the manual gas shutoff valve external to the unit.
2. Turn off the electrical power supply to the unit.
3. Set the room thermostat to its lowest possible setting.
4. Remove the heat exchanger door on the side of the unit by
removing the screws.
IMPORTANT: This unit is equipped with an ignition device which
automatically lights the main burner. Do not try to light burner by
any other method.
5. Move the gas control valve switch to the OFF position.
NOTE: Do not force the switch to turn.
6. Wait 5 minutes to clear out any gas.
7. Check for a gas odor around the unit, including near the
ground because some types of gas are heavier than air.
