Indoor Unit Installation

6.

Drain piping.

1) Connect the drain hose, as described right.

2) Remove the air filters and pour some water into the drain pan to check the water 

flows smoothly.

3) When drain hose requires extension, obtain an extension hose commercially avail-

able. 
Be sure to thermally insulate the indoor section of the extension hose.

4) When connecting a rigid polyvinyl chloride pipe 

(nominal diameter 13mm) directly to the drain 
hose attached to the indoor unit as with embed-
ded piping work, use any commercially available 
drain socket (nominal diameter 13mm) as a 
joint.

Refrigerant piping work

, install as described in the installation manual supplied with the Multi outdoor unit.

1.

Flaring the pipe end.

1) Cut the pipe end with a pipe cutter.
2) Remove burrs with the cut surface facing downward 

so that the chips do not enter the pipe.

3) Put the flare nut on the pipe.
4) Flare the pipe.
5) Check that the flaring is properly made.

WARNING

1) Do not use mineral oil on flared part.
2) Prevent mineral oil from getting into the system as this would reduce the lifetime of the units.
3) Never use piping which has been used for previous installations. Only use parts which are delivered with the unit.
4) Do never install a drier to this R410A unit in order to guarantee its lifetime.
5) The drying material may dissolve and damage the system.
6) Incomplete flaring may cause refrigerant gas leakage.

The drain hose should 
be inclined downward.

No trap is permitted.

Do not put the end 
of the hose in water.
