●
If other commercially available hose bands are
used, the drain hose may become pinched or wrin-
kled and there is danger of water leakage. There-
fore be sure to use the supplied hose bands. When
sliding the hose bands, be careful to avoid scratch-
ing the drain hose.
●
Do not use adhesive when connecting the supplied
drain hose to the drain port (either on the main unit
or the PVC pipe).
●
Wrap the hose with the supplied drain hose insula-
tion and use the 4 twist ties so that the hose is
insulated with no gaps.
●
Connect the drain piping so that it slopes down-
ward from the unit to the outside. (Fig. 3-53)
●
Never allow traps to occur in the course of the piping.
●
Insulate any piping inside the room to prevent drip-
ping.
●
After the drain piping, pour water into the drain pan
to check that the water drains smoothly.
●
If the drain hose is to be raised, use the optional
drain up kit.
The drain hose can be raised 60 cm above the top
of the main unit. (For details, refer to the manual
for the optional part.)
* If the drain hose is routed
through the left side, refer
to Fig. 3-51, and follow the
procedure above to install
the hose. Rettach the rub-
ber stopper removed earlier onto the right side.
The rubber stopper can be inserted easily by using
a screwdriver or similar tool to press the stopper
into the drain port on the main unit. Press the stop-
per into the main unit drain port as far as it will go.
