4.Drain hose installation (Example;4-way cassette type)

Care must be taken when installing the drain hose for the indoor unit to ensure that any condensate water is correctly drained outside.

1) Insert the flexible hose to the drain hose port.

Note Attach the drain hose to the drain hose port with an adhesive for PVC and tape to prevent water leaks, then secure the hose with a band etc..(The band is not supplied with the air conditioner.)

2)Install the drain hose so that its length can be as short as possible. Internal diameter of the drain hose should be the same or slightly bigger than the external diameter of the drain hose port.

Inner diameter of the drain hose

32mm(Outer diameter)

Note Give a slightly slant to the drain hose for proper drainage of condensate.

Secure the drain hose with an adhesive for PVC and tape not to be separated from the unit.

3)Wrap the drain hose with the insulation drain as shown in figure and secure it.

CAUTION

Check that the indoor unit is level with the ceiling by using the leveler.

Install air ventilation to drain condensate water smoothly.

If it is necessary to increase the height of the drain hose somewhat, the portion directly after 30cm. If it is raised higher than 50cm, there can be water leaks.

Do not give the hose and upward gradient after the connection port.

This will cause water to flow backwards when the unit is stopped, resulting in water leaks.

Upward gradient

Do not apply force to the piping on the unit side when connecting the drain hose. The hose should not be allowed to hang loose from its connection to the unit. Fasten the hose to a wall, frame or other support as close to the unit as possible.
