Indoor Unit Installation

Drain piping

1) Connect the drain hose, as described on the right.

• Avoid placing the end of the drain hose in a drainage location that could

cause bad odors or corrosive gas to flow backward into the outlet.

• The drainage water may change color due to bacteria or other

organisms. Place in a location where the flow of drainage water will not

cause a problem.

• Minimize the number of bends in the drain hose as much as possible.

If bending the drain hose, bend it gently.

2) Remove the air filters and transfer some water to the indoor heat

exchanger by pouring water into the drain pan.

3) Make sure that water flows out of the drain hose.

4) If drain hose extension or embedded drain piping is required, use

appropriate parts that match the hose front end.

• When drain hose requires extension, obtain an extension

hose with an inner diameter of 5/8 inch (16mm).

Be sure to thermally insulate the indoor section of the

extension hose.

• When connecting a rigid polyvinyl chloride pipe

(nominal diameter 1/2 inch (13mm)) directly to

the drain hose attached to the indoor unit as with

embedded piping work, use any commercially

available drain socket (nominal diameter 1/2 inch

(13mm)) as a joint.
