(g)

VP-30

Secure the elevation as high as possible (approx. 100 mm)

A downhill grade of 1/100 or more

When constructing drain piping for several units, position the

common pipe about 100 mm below the drain outlet of each

unit as shown in the sketch. Use VP-30(11/4") or thicker pipe

for this purpose.

(d)

(e)

The stiff PVC pipe put indoor side should be heat insulated.

(f)

Avoid putting the outlet of drain hose in the places with irritant gas generated. Do not insert the drain hose directly into

drainage, where the gas with sulfur may be generated.

Because the drain spout is at the position, which negative

pressure may occur. So with the rise of water level in the drain

pan, water leakage may occur. In order to prevent water leakage,

we designed a backwater bend. The structure of backwater

bend should be able to be cleaned. As the right figure shown,

use T type joint. The backwater bend is set near the air

conditioner.

As figure shown, set a backwater bend in the middle of drain

hose.

Drainage Test

Conduct a drainage test after completion of the electrical work.

During the trial, make sure that drain flows properly through the piping and that no

water leaks from connections.

In case of a new building, conduct the test before it is furnished with the ceiling.

Be sure to conduct this test even when the unit is installed in the heating season.

Procedures

Supply about 1000 cc of water to the unit through the air outlet using a feed water pump.

Check the drain while cooling operation.

Adhesion

For drain pipe, use hard PVC general purpose pipe VP-25(I.D.1")

which can be purchased locally. When connecting, insert a

PVC pipe end securely into the drain socket before tightening

securely using the attached drain hose and clamp. Adhesive

must not be used connection of the drain socket and drain

hose (accessory).

(c)

Drain piping should always be in a downhill grade (1/50~1/100) and avoid riding across an elevation or making traps.

When connecting the drain pipe to unit, pay suffcient attention

not to apply excess force to the piping on the unit side. Also,

fix the piping at a point as close as possible to the unit.
