Installation Manual For Indoor Unit

(d)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.

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

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

1/100 or more

 

(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.

(g)Backwater bend

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 below 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

H1=100mm or the static pressure of air sending motor H2=1/2H1 (or between 50~100mm)

1Conduct a drainage test after completion of the electrical work.

2During the trial, make sure that drain flows properly through the piping and that no water leaks from connections.

3In case of a new building, conduct the test before it is furnished with the ceiling.

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

Procedures

1Supply about 1000 cc of water to the unit through the air outlet using a feed water pump.

2Check the drain while cooling operation.
