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 attached 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 insula-
tion 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) Choose one hole to discharge drain and install the drain socket (1) to the hole.
2) Close the rest of the holes with the drain caps (2).
3) Connect the soft PVC hose (L) of 25 mm in the inside diameter on the market with the drain socket (1) and lead drain.
Note:
Install the unit horizontally.
Do not use the drain socket (1) and the drain caps (2) in the cold regions. Drain may freeze and it makes the fan stop.
The outdoor unit produces condensate during the heating operation. Select the installation place to ensure to prevent the outdoor unit and/or the grounds from
being wet by drain water or damaged by frozen drain water.
