1.3.2 Drain Piping Work
(1) Carry out the drain piping.
•
Make sure piping provides proper drainage.
•
You can select whether to bring the drain piping our from the rear right, right, rear left, or left.
For rear right-facing and right-facing situations, refer to “1.3.1. Refrigerant Piping Work” on
page 44 for rear left-facing and left-facing situations. (Refer to Fig. 18)
•
When setting piping facing left, move the rubber stopper and insulation which are attached
to the drain pipe connection hole on the left side of the indoor unit to the right-side drain pipe
connection hole. When doing this, insert the rubber stopper all the way in to prevent a water
leakage.
•
Make sure the pipe diameter is the same or bigger than the branch piping. (vinyl-chloride
piping, nominal diameter 20 mm, external diameter 26 mm)
•
Make sure the piping is short, has at least a 1/100 slope, and can prevent air pockets from
forming. (Refer to Fig. 19)
•
Be sure to use the included drain hose (1) and clamp (2).
Also, insert the drain hose completely into the drain socket, and securely attach the clamp
bracket inside the gray tape area on the inserted tip of the drain hose. (Refer to Fig. 20)
Screw the screws on the clamp bracket until there is 4 mm left. (Pay attention to the direction
of the attachment to prevent the clamp bracket from coming into contact with the suction
grille.) (Refer to Fig. 21)
