General Information
3.2.9 Drain Piping for Each Model
Ceiling Mounted
Cassette Type
(FXFQ-M Multi-
flow)
1. Rig drain piping
Note:
Lay pipes so as to ensure that drainage can occur with no problems.
Employ a pipe with either the same diameter or with the diameter larger (excluding the raising section) than
that of the connecting pipe (PVC pipe, nominal diameter 25 mm, outside diameter 32 mm).
Keep the drain pipe short and sloping downwards at a gradient of at least 1/100 to prevent air pockets from
forming.
If the drain hose cannot be sufficiently set on a slope, execute the drain raising piping.
To keep the drain hose from sagging, space hanging wires every 40 to 60 inches.

Use the attached drain hose (1) and clamp (2).
Insert the drain hose into the drain socket up to the base, and tighten the clamp securely within the portion
of a white tape of the hose-inserted tip. Tighten the clamp until the screw head is less than 3/16" from the
hose.
Wrap the attached sealing pad (10) over the clamp and drain hose to insulate.
Make sure that heat insulation work is executed on the following 2 spots to prevent any possible water leak-
age due to dew condensation.

<PRECAUTIONS FOR DRAIN RAISING PIPING>
Install the drain raising pipes at a height of less than 21 5/8".

Install the drain raising pipes at a right angle to the indoor unit and no more than 11 13/16" from the unit.

To ensure no excessive pressure is applied to the included drain hose (1), do not bend or twist when install-
ing. (This may cause leakage.)
If converging multiple drain pipes, install according to the procedure shown below.
Select converging drain pipes whose gauge is suitable for the operating capacity of the unit.
