1-5. INSTALLATION DIAGRAM
Units should be installed by licensed contractor according to local code requirements.
After the leak test, apply insulat-
ing material tightly so that there is
no gap.
When the piping is to be at-
tached to a wall containing metals
(tin plated) or metal netting, use
a chemically treated wooden
piece 20 mm or thicker between
the wall and the piping or wrap 7
to 8 turns of insulation vinyl tape
around the piping.
To use existing piping, perform
COOL operation for 30 minutes
and pump down before removing
the old air conditioner. Remake
flare according to the dimension
for new refrigerant.

1-6. DRAIN PIPING FOR OUTDOOR UNIT
Please perform the drain piping work only when draining from one place.
1) Provide drain piping before indoor and outdoor piping connection.
2) Connect the soft PVC hose (L) I.D.15 mm as shown in the illustration.
3) Make sure to provide drain piping with a downhill grade for easy drain flow.
Note:
Install the unit horizontally.
Do not use the drain socket (1) in the cold regions. Drain may freeze and it makes
the fan stop.
The outdoor unit produces condensate during the heating operation. Select the in-
stallation place to ensure to prevent the outdoor unit and/or the grounds from being
wet by drain water or damaged by frozen drain water.
