Drain Test
• Connect the main drain pipe to the flexible drain.
• Feed water from flexible drain hose to check the piping for leakage.
• When the test is completed, connect the flexible drain hose to the drain connector on the indoor unit.
NOTE
This Indoor Unit uses a drain pump for condensed water drainage. Install the unit horizontally to prevent
water leakage or condensation around the air outlet.

The indoor unit must be installed such that there is no short circuit of the cool discharge. Respect the
installation clearance. Do not put the indoor unit where there is direct sunlight on unit. The location is suitable
for piping and drainage and it must have a large distance between a door and unit.
