3-36-2. Installing the Drain Pipe
CAUTION
●
Do not apply force to the drain port when connecting the
drain pipe. Install and fix it near the indoor unit as close
as possible.
●
Do not use adhesive when connecting the drain port pipe
and the drain hose.
(1) How to Install the Drain Pipe
1) First insert the supplied hose band into the drain port
pipe. Then make sure the head of the screw is facing
toward a technical engineer when placing the screw of
the hose band at an upward angle.
2) Insert the soft PVC socket of the supplied drain hose
to the drain port pipe. Do not use adhesive when
connecting the drain hose to the drain port pipe.
Insert it until the tip of the drain hose contacts the circular
projection rib of the drain port pipe.

Do not use adhesive here.
* Drain port may possibly be damaged if
PVC adhesive is used.
Do not make hose band overlap the circular projection
rib and the sealed ciculation projection of the drain
port pipe. (Torque: 2.5 N·m - 3.4 N·m)

Approx. 30 mm
* After checking the drainage, wrap the supplied packing and drain pipe insulator around the pipe.
3) Move the hose band so that the center position of the
hose band can be placed approx. 30 mm away from the
external plate of the indoor unit. (Fig. 3-95)
4) Screw the drain hose tightly facing the screw of the hose
band upward. (Torque: 2.5 N·m - 3.4 N·m) (If the screw
is tightened beneath the drain hose, the troubles will be
generated.) Pay attention not to make hose band overlap
the circular projection rib and the sealed ciculation
projection of the drain port pipe.
5) Apply approx. 2 g of adhesive on both sides of the drain
hose without connection of the hard PVC socket and the
hard PVC joint (VP25) in the local supply.
6) Connect the drain hose and the hard PVC joint so that
the adhesive area of both sides can be overlapped.
Wipe off the protrusion-adhesive with a soft cloth.

3-36-3. Checking the Drainage
Be careful since the fan will start
CAUTION
when you short the pin on the
indoor control board.
After wiring and drain piping are completed, use the following
procedure to check that the water will drain smoothly. For
this, prepare a bucket and wiping cloth to catch and wipe up
spilled water.
(1) Connect power to the power terminal board (R, S
terminals) inside the electrical component box.
(2) Slowly pour about 1,200 cc of water into the drain pan to
check drainage. (Fig. 3-96)
(3) Short the check pin (CHK) on the indoor control board
and operate the drain pump. Check the water flow
through the transparent drain pipe and see if there is any
leakage.
(4) When the check of drainage is complete, open the check
pin (CHK) and remount the tube cover.
(5) Checkpoint after installation
After installation of indoor and outdoor units, panels and electrical wiring, check the following items.
Checkpoint
Make sure whether indoor and outdoor units
1
are correctly installed.
2 Make sure whether gas leakage is tested.
Make sure whether insulation is completed.
3
(Refrigerant piping and drain piping)
Make sure whether drain water is running
4
smoothly.
Make sure whether the power voltage
5
matches the nameplate.
Make sure whether there is miswiring or
6
incorrect connection.
Make sure whether the ground construction
7
is completed.
Make sure whether the wire gauge is
8
followed by the recommended specifications.
Make sure whether the air intake and air
9 outlet of the indoor and outdoor units are
sealed by obstacles.
