Drain Pipe
(1) See Fig. 6.1 for connection point of drain pipe.
(2) Find a PVC pipe with an outside diameter of 1-1/4 in.
(3) Fix the PVC pipe to drain pipe through adhesive and
factory-supplied clamp. The downward inclination of
drain pipe is 1/25~1/100 in.
(4) Make thermal insulation after the proper connection
of drain pipe.

The drain pipe installed shall slope down; otherwise, the
condensate may flow back and leak into the room when
the indoor unit is turned off.
(2) The drain pipe shall not be connected with sewage pipe
or other drain pipes.
(3) Where the main drain is connected to other indoor units,
each indoor unit must be higher than the main. Select
drain pipes in ample size depending on the refrigerating
capacity and quantity of indoor units.
(4) Check if water flows without obstruction following the
procedure shown below after the proper connection of
wires and drain pipes.
a. Turn on the power
b. Fill the drain pan with 68oz(2L) or 84oz(2.5L) of water.
c. Check and ensure the water flows without obstruction
and no leakage exists. Pour 68oz(2L) of water if no
water flows out of pipe end.
