– Install the drain pipe with downward gradient (1/50 to 1/100) and so there are no rises or traps in
the pipe.
– Use general hard polyvinyl chloride pipe (VP25) (O.D. 2 in [32 mm]) and connect it with adhe-
sive (polyvinyl chloride) so that there is no leakage.
– When the pipe is long, install supporters.
– Do not perform air bleeding.
– Always heat insulate the indoor side of the drain pipe.
