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 instal-
lation place to ensure to prevent the outdoor unit and/or the grounds from being wet
by drain water or damaged by frozen drain water.
En-3
After the leak test, apply insulating
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 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.
