9-4. Installing the Drain Piping
(1) Prepare standard hard PVC pipe (O.D. 32 mm) for the drain and
use the supplied drain socket to prevent water leaks.
The PVC pipe must be purchased separately.
When doing this, apply adhesive for the PVC pipe at the
connection point.
(2) If connecting a drain socket (supplied) to the threaded drain port,
first wrap the drain port threads with sealing tape, then connect
the joint. (Fig. 1-27)
(3) Ensure the drain pipe has a downward slant (1/100 or more).
(See the Fig. 1-28)
(4) The drain pipe with a trap should be installed away from the
indoor unit.
(5) Do not forcibly install the drain pipe to the indoor unit tubing.
If forcibly installed, it may result in water leakage.
(6) The drain pipe should be fixed at the nearest of the indoor unit.
Failure to do so may result in water leakage.
(7) Do not attach any air purge equipment.
If attached, drain water may result in splashing out of the drain
pipe.
(8) When the drain piping is completed, perform the water leak test
and check for a water leak.
If detected, it may result in water leakage or condensation.
(9) When the drain piping is completed, perform the drainage test
if the water drains smoothly.
If not draining smoothly, it may result in water leakage or
condensation.
(10) When the drain piping work is finished securely, wrap the
insulation material around the indoor side drain pipe.
At this time, do not wrap together with the refrigerant tubing.
If wraped together, the drain pipe is lifted and water drainage will
not be operated.
Coincidentally, the water comes out of the drain pan and it can
lead to water leakage.

Note:
Since the drain trap area easily accumulates
the dust inside the drain pipe, necessarily
install the plug in order to clean out the drain
trap.
