1-6. DRAIN PIPING FOR OUTDOOR UNIT
1) Perform the drain piping work only when draining from one place.
2) Provide drain piping before indoor and outdoor piping connection.
3) Attach the drain socket to one of the several drain holes.
Fix the drain socket into the drain hole of the base using the catches to secure it in place.
4) Connect the soft PVC hose I.D.15 mm as shown in the illustration.
5) Make sure to provide drain piping with a downhill grade for easy drain flow.
6) Glue the drain caps to close all the other unnecessary holes with the glue (Prepare in the
field).
Note:
Apply the glue securely, as the glue (Prepare in the field) will work as seal to prevent water
from leaking.
Use the adhesive for the rubber and metal.
Attention
The outdoor unit is provided with several holes for drainage at the bottom to make drainage easier.
The drain socket is used to close the unnecessary holes and centralize the drainage when using
the drain tube at the installation place.
Do not to use the drain socket in cold region. The drain tube can be frozen.

ing or wrap 7 to 8 turns of insulation
