(4) Drain piping
(a) Drain piping should always be in a downhill grade (1/50-1/100) and avoid riding across an elevation or makeing traps.
(b) When connecting the drain pipe to the 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.
(c) For drain pipe, use hard PVC general purpose pipe VP-25 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).
(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 below. Use VP-30 or thicher 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.
