4.6 Installing drainage hose
NOTE
:
♦
Install the drainage hose.
♦
Install the drainage hose with downward gradient (1/50 t0 1/100) and there should be no
rises or traps in the pipe.
♦
Use general hard polyvinyl chloride pipe (VP25) [outside diameter l -1/4" (32mm)] and
connect it with adhesive (polyvinyf chloride) so that there is no leakage.
♦
When the pipe is long, install supporters.
♦
Always heat insulate the indoor side of the drainage hose.
♦
When desiring a high drain pipe height, raise it up to 15" (400 mm) or less from the ceiling
within a range of 6" (150mm) from the body. T he raised height over this range will cause leakage.
