General Information
(1) Carry out the drain piping
!
The diameter of the drain pipe should be greater than or equal to the diameter of the
connecting pipe (vinyl tube, pipe size: 25 mm; outer dimension: 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 1 to 1.5 m.
Caution
Setting the unit at an angle opposite to the drain piping might cause leaks.
!
Use the attached drain hose and clamp metal.
Insert the drain hose into the drain socket, up to the white tape. Tighten the clamp until the
screw head is less than 4mm from the hose.
!
Wrap the attached sealing pad over the clamp and drain hose to insulate.
!
Insulate the drain hose inside the building.
(PRECAUTIONS FOR DRAIN RAISING PIPING)
!
Install the drain raising pipes at a height of less than 310 mm.
!
Install the drain raising pipes at a right angle to the indoor unit and no more than 300 mm
from the unit.
!
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.
