(1) Drain hose connection

he drain hose is connected below the refrigerant tubing.

(2) Installing the drain hose

irst insert the drain hose (supplied) to the hose band

(

supplied)

and then install the drain hose to the unit drain port.

Insert until the drain hose bumps to the end.
Attach the hose band to make the fixed portion 45°upper

gradient according to a vinyl tape (

not supplied)

of the drain

hose (supplied).

(Fig. 1-203)

  Hose band screw torque is 2.6 - 3.0 lbf·inch (30 - 35 N·cm).
  Wind the vinyl tape not to blow up the hose band.
  Connect both the drain hose and PVC pipe (VP20 or similar

material, not supplied). Insert until the PVC pipe bumps to

the end and adhere with PVC adhesive.

CAUTION

Wrap the drain insulator (supplied) between the connection

of the drain hose and tubing not to expose the copper

tubing. Also, wrap the hose band together.

Wrap the hose band with the drain insulator, where the

screw is located facing upward (Fig. 1-203). Then, tighten the

insulator with a vinyl tape not to cause the detachment. If

the tubing parts remain exposed, condensation may occur.

Be sure to use the supplied drain hose.

If other commercially available hose bands are used, the

drain hose may become pinched or wrinkled and there is

danger of water leakage.

Therefore be sure to use the supplied hose bands.

Connect the drain pipe so that it slopes downward from the

unit to the outside. (Fig. 1-202)
