Multiple Power Sources May Be Present - Whirlpool WAHMS Installation Instructions And Owner's Manual

Have all cabinet openings and wiring been sealed?
Is the indoor coil orifice sized correct?
Have all unused orifice replacement parts and packaging
been disposed of/recycled?
Is the filter clean, in place, and of adequate size?
Is the wiring neat, correct, and in accordance with the wiring
diagram?
Is the air handler properly grounded and fused?
Is the thermostat correctly wired and in a good location?
Are all access panels in place and secure?
Check Blower Operation
1. Set the thermostat to FAN ON.
2. The indoor blower should come on.
Check Electric Heater (If Used)
1. Set the thermostat to call for auxiliary heat (approximately 5°F
above ambient temperature). The indoor blower and auxiliary
heat should come on together. Allow a minimum of 3 minutes
for all sequencers to cycle on.
2. Set the thermostat so it does not call for heat. Allow up to
5 minutes for all sequencers to cycle off.
Check Airflow
Cooling Blower Speed
For proper cooling operation, the airflow through the indoor
coil should be between 350 and 450 CFM per ton of cooling
capacity (or 350 to 450 CFM per 12,000 Btu/h) based on the
rating of the outdoor unit.
The cooling blower speed is factory-configured to provide the
correct airflow for an outdoor unit that matches the maximum
cooling capacity rating of the air handler.
If the outdoor unit is smaller than the maximum cooling
capacity rating for the air handler, the cooling blower speed
may need to be changed. Refer to the Blower Performance
Chart.
IMPORTANT: The cooling blower speed must be set to provide a
minimum of 350 CFM airflow per ton (1,200 Btu/h) of outdoor
cooling capacity.
WARNING
HIGH VOLTAGE!

WVAHM/WAHMS Motor
Motor Speed Adjustment
The motors in all WVAHM and WAHMS motors are multi-speed
PSC motors. The color of the wire coming from the motor to the
"COM" terminal on the control board defines in which speed the
motor will operate. The black wire represents high speed, the red
wire represents low speed and the blue wire (select models only)
represents medium speed.
To change speeds, remove the wire attached to the COM
terminal on the control board, and swap it with the wire on
terminal M1 or M2 with the color that will give the desired speed.
NOTE: On some models, not all speed taps are allowable for
certain electric heat applications. Refer to the air handler series
and ratings plate for minimum speed.
