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.

(e)Be sure to provide heat insulation to hard PVC pipes of indoor placement.

(f)Do not ever provide an air vent.

(g)The height of the drain head can be elevated up to a point 500 mm above the ceiling, and when an obstacle exists in the ceiling space, elevate the piping to avoid the obstacle using an elbow or corresponding gadget. When doing this, if the stretch for the needed height is higher than 500 mm, the back- flow quantity of drain at the event of interruption of the operation gets too much and it may cause overflow at the drain pan. Therefore, make the height of the drain pipe within the distance given in the sketch below.

(h)Avoid positioning the drain piping outlet at a place where generation of odor may be stimulated. Do not lead the drain piping direct into a sewer from where sulfur gas may generate.

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

Drainage Test

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.

4Be 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.

Remove grommet. Make sure to install it back after test.

Insert water supply hose for 20 mm ~ 30 mm to supply water.

(Insert hose facing toward bottom.)

Attached drain hose clamp

Main unit

Drain piping

Drain situation can be checked with transparent socket

Pour water into a convex joint.

(In the electrical work has not been completed, connect a convex joint in the drain pipe connection to provide a water inlet. Then, check if water leaks from the piping system and that drain flows through the drain pipe normally.)
