How to Attach Drain Pan (Some Models)

The air conditioner employs a proper drain method whereby the condensed water (moisture removed from the
air) is drained to the outside.

In very humid weather, (and for reverse cycle models in the reverse mode) excessive condensate water removed
from the air may cause some water to collect. To remove this excess water you can install the drain pan as
detailed below.

1. Take the drain pan which is located in the air discharge.

2. Remove the hole rubber from the base-pan (for some models).

3. Install the drain pan to the right corner of the cabinet with 4 (or 2)
screws.

4. Connect the drain hose to the outlet located at the bottom of the
drain pan.You can purchase the drain hose or tubing locally to
satisfy your particular needs. (Drain hose is not supplied).

Outdoor Coils

The coils on the outdoor side of the air conditioner should be checked
regularly. If they are clogged with dirt or soot they may be professionally
steam cleaned, a service available through a dealer.
