7. DRAIN PIPING WORK
(1) Rig drain piping
• As for drain work, perform piping in such a manner that water can be drained properly.
• Employ a pipe with either the same diameter or with the diameter larger (excluding the raising section) than
that of the connecting pipe (PVC pipe, nominal diameter 25 mm, outside diameter 32 mm).
• Keep the drain pipe short and sloping downwards at a gradient of at least 1/100 to prevent air pockets from
forming.
• If the drain pipe cannot be sufficiently set on a slope, execute the drain raising piping.
• To keep the drain pipe from sagging, space hanging wires every 1 to 1.5 m.
CAUTION
Water accumulating in the drain piping can cause the drain to clog.
• Use the attached drain hose (1) and Metal clamp (2).
• Connect the drain hose (1) to the stage part of the drain socket and securely tighten the metal clamp (2)
with the tape on the insertion end of the hose.
Tighten the screw of the metal clamp (2) until the remainder will become 4 mm or less.
• Wrap the attached sealing pad (10) over the Metal clamp and drain hose to insulate.
• Make sure that thermal insulation work is executed on the following 2 spots to prevent any possible water
leakage due to dew condensation.
