PREPARATION FOR INSTALLATION
1. Remove old unit from wall sleeve and dispose of properly.
IMPORTANT: It is illegal to discharge refrigerant
into the atmosphere. Use proper reclaiming methods
and equipment when installing or servicing a
RetroAire Single Motor PTAC.
2. Inspect wall sleeve for rust or damage. Clean, replace or
repair as necessary.
3. Remove or repair old weather seals and note locations
for installation of new seals. Contact factory for weather
seals if needed.

remove any obstructions (draperies, bedspreads, etc.)

supply air grille.

or frayed wires.
