5 DRAIN PIPING WORK

Piping material

•For laying pipes underground, use hard vinyl chloride pipe. VP25 (Inner diamater Ø32mm)

Piping and cautions

•Set drain side of pipe at downward slope. (1/100 or more)

•Be sure to apply thermal insulation (foaming polyethylene, 10mm-thickness or more) for pipes passing through the room.

•Adhere the connecting sections with vinyl chloride agent surely so that no water leakage is caused.

•Apply adhesive agent without unevenness around the portion approx. 40mm from the end of hard polyvinyl-chloride pipe.

•Push the vinyl pipe in the drain socket completely up to the end of the socket.

•Do not apply strength to the connecting part until the adhesive agent has dried and hardened.

•Support the piping with hanging bracket so that the force is not applied to connection sections of pipe and pipe is not waved.

NOTES :

•Do not make slack or trap at halfway across piping.

•Set pipes so that the end of drain pipe is not dipped in water, and also keep space 50mm or more to the ground.

•After piping work, check if water drains smoothly.

•Hole should be made at a slight downward slant to the outdoor side.

•When connecting extension drain hose, insulate the connecting part of extension drain hose with shield pipe.

•As shown in the figure, set the collective piping such as the ceiling duct so that waste water does not back up from the main pipe.

50 mm or more

Do not put the drain hose end into water or drainage.

Thermal-insulating process

•After checking water drain, be sure to apply the thermal-insulating for connecting portion of the pipes.

•Apply taping so that there is no clearance on the fitting part of thermal-insulator of the main unit with the insulator procured locally.
