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)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)

Hole for check

Calculate the draft and external static pressure and select the length, shape and blowout.

ABlowout duct

2-spot, 3-spot and 4-spot with ABlowout duct 200 type duct are the standard specifications. Determine the number of spots based on following table.

Note (1) Shield the central blowout hole for 2-spot.

(2) Shield the blowout hole around the center for 3-spot.

Limit the difference in length between spots at less than 2:1. Reduce the length of duct as much as possible.

Reduce the number of bends as much as possible. (Corner R should be as larger as possible.)
