(1) The position of the drain pipe connection is
shown in Fig. 6.1.
(2) Prepare a polyvinyl chloride pipe with a
32mm outer diameter.
(3) Fasten the tubing to the drain hose with the
adhesive agent and the factory-supplied
clamp. The drain pipe must be performed
with a down-slope pitch of 1/25 to 1/100.

This drain pipe shall be
separating from other pipes.
Where the relative humidity of air inlet or
ambient air exceeds 80%, an auxiliary water pan
shall be fabricated at installation site and placed
under the indoor unit, as shown in Fig. 6.2.

(1) 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 water pan with 1.5L or 2L of water.
c. Check and ensure the water flows without
obstruction and no leakage exists. Pour 1.5L of
water if no water flows out of pipe end.
● Inject water via air outlet.
Insert the end of hose between
heat exchanger and water pan.
