SLEEVE / DRAIN
Inspect the sleeve and drain system periodically (at least yearly or bi-yearly) and clean of all obstructions and
debris. Clean both areas with an antibacterial and antifungal cleaner. Rinse both items thoroughly with water and
ensure that the drain outlets are operating correctly. Check the sealant around the sleeve and reseal areas as
needed.
DECORATIVE FRONT COVER
Clean the front cover when needed. Use a mild detergent. Wash and rinse with warm water. Allow it to dry
thoroughly before reinstalling it in the chassis.
The decorative front and the cabinet can be cleaned with warm water and a mild liquid detergent. Do NOT use
solvents or hydrocarbon based cleaners such as acetone, naphtha, gasoline, benzene, etc.
Use a damp (not wet) cloth when cleaning the control area to prevent water from entering the unit, and possibly
damaging the electronic control.
CLEARANCES
Inspect the surrounding area (inside and outside) to ensure that the unit’s clearances have not been compromised or
altered.
ROUTINE MAINTENANCE (Continued)
Do not drill holes in the bottom of the drain pan or the
underside of the unit. Not following this notice could
result in damage to the unit or condensate water leaking
inappropriately which could cause water damage to
surrounding property.
