After performing drain piping work and electrical wiring,
check to ensure that water flows smoothly as in the
following procedure:
Checking Unit without Drain-up Mechanism
- Pour approximately 1.8 liters of water into the drain pan.
- Check to ensure that the water flows smoothly or
whether no water leakage occurs. When water cannot
be found at the end of the drain piping, pour another
approximately 1.8 liters of water into the drain pan.
NOTE:
Pay attention to the thickness of the insulation when
the left side piping is performed. If it is too thick,
piping can not be installed in the unit.
4.2. DRAIN PIPE CONNECTION
1. Prepare a polyvinyl chloride pipe with a 18.5 mm outer
diameter.
2. Insulate the drain pipe after connecting the drain hose
as shown.
