could cause damage?
Have ALL unused drain pan ports been properly
plugged?
Has the condensate line been properly sized, run,
trapped, pitched, and tested?
Is the duct system correctly sized, run, sealed, and
insulated?
Have all cabinet openings and wiring been sealed?
Is the indoor coil factory‐installed TXV properly sized
for the outdoor unit being used?
Have all unused parts and packaging been disposed
of?
Is the filter clean, in place, and of adequate size?
Is the wiring neat, correct, and in accordance with the

CHECK BLOWER OPERATION
Set thermostat to FAN ON.
The indoor blower should come on.
CHECK COOLING OPERATION
Set thermostat to force a call for cooling (approximately
5ºF lower than the indoor ambient temperature).
The outdoor unit should come on immediately and the
indoor blower should start between 30 - 60 seconds
later.
Check the airflow from a register to confirm that the
system is moving cooled air.
