50 General Information

Ceiling Mounted

Duct Type

(FXMQ-M)

Note: If installing central drain piping, install according to the following right figure.

(Install a drain trap for each indoor unit.)

• After piping work is finished, check drainage flows smoothly.

<<Rig the drain pipe as shown below and take measures against

condensation. Improperly rigged piping could lead to leaks and

eventually wet furniture and belongings.>>

<<Insulate the drain hose inside the buildings>>

(1) Install the drain pipes.

• Keep piping as short as possible and slope it downwards so that air may not

remaine trapped inside the pipe.

• Keep pipe size equal to or greater than that of the connecting pipe (Vinyl pipe of 1"

norminal diam. and 1 1/4" outer diam.).

• Use the attached drain hose and clamp.

Tighten the clamp firmly.

• Insulate the clamp metal with the attached sealing pad.

• There is negative pressure inside the unit relative to atmospheric pressure

when the unit is running, so be sure to provide drain frap on the drain outlet.

(See the figure)

• In order to prevent foreign matter from building up inside the piping, you

should avoid curves as much as possible, and arrange so the trap can be

cleaned.
