(PRECAUTIONS FOR DRAIN RAISING PIPING)
General Information
The diameter of the drain pipe should be greater than or equal to the diameter of the connecting pipe
(vinyl tube; pipe size: 25mm; outer dimension: 32mm).
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.
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 4 mm from the hose.
Wrap the attached sealing pad over the clamp and drain hose to insulate.
Insulate the drain hose inside the building.
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.
