Installation

• 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.

• If increasing the height of the drain pipe is necessary to set the drain hose at a sufficient

slope, installing a vertical drain pipe within 11.8

in. (300 mm) from the drain hose port (see

A). If raised higher than 21.65

in. (550 mm), water leaks may result (see “C” in figure).

• Install the air vent at least 3.04 in. (100 mm) above the highest point of the drain pipe.

Centralized Drainage

If the installation requires more than three indoor units, install the main air vent at the front of the

indoor unit that is farthest from the main drain.

It may be necessary to install individual air vents to prevent water flowing back to each indoor unit.

See figure below.

Testing the Drainage

After completing the installation, test the drainage to make sure there are no leaks:

3.28–4.92 ft

(1–1.5 m)

A = 11.8 in. (300 mm) or less

B = 3.28–4.92 ft (1–1.5 m)

C = 21.65 in. (550 mm) or less

D = 3.94 in. (100 mm) or more

E = 0.79 in. (20 mm) or more
