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 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.
En-5
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.
