IMPORTANT NOTES:
1. The unit is equipped with a rubber-grommet-mounted
compressor. These grommets are factory set and require
no adjustment.
2. Obstruction to air flow must be checked and removed.
Check the indoor and outdoor grilles for obstructions. The
unit must be located where curtains, furniture, trees, or
other objects do not block air flow to and from the unit. If air
is obstructed and/or deflected back into the unit, the air
conditioner’s compressor may cycle on and off rapidly.
This could cause damage to the compressor.
