In humid weather, excess water may cause the BASE PAN to
overflow. To drain the water, remove the DRAIN CAP and
secure the DRAIN PIPE to the rear hole of the BASE PAN.
(except heat pump models)

The air conditioner employs a proper drain method

whereby the condensate 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. (for heat
pump models and over 18K cooling models)

1. Take the drain pan which is shipped in the air discharge or

on the barrier.

2. Remove the rubber plug from the bottom of the base pan.
3. Install the drain pan over the corner of the cabinet where you

removed the plug 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).

5. Select the most appropriate connection from among the

following figures (by considering the hole of the unit) to fit
drain pan to your own unit.
