(2) After piping work is finished, check drainage flows smoothly.
•
Test the drainage by pouring around 1000cc of water into the drain pan through the inspection hole
by removing the maintenance cover (10 screws) or through the outlet duct joint of supply air to room
(SA). (Refer to Fig. 8)

CAUTION
When installing the water supply piping, wash the pipes with tap water so that all dirt is removed from them
or install a drain valve somewhere along the piping and drain the pipes thoroughly until the water flowing
through them is clear. Make sure no cutting oils or detergents get into the pipes.
•
Connect the water supply piping with strainer (accessory), other pipings and valves (locally procured)
to the indoor unit as shown in the figure at below.
[PRECAUTION]
•
When installing the water supply piping, do not pass piping in front of the maintenance cover, as this will
make it impossible to remove the humidifier element.
•
Include the water supply piping with strainer (included), a water supply shut-off valve, and a drain valve (both
locally procured) somewhere along the water supply piping that can be reached from the inspection hole.
•
It is impossible to connect the water supply piping directly to public piping. Use a cistern tank (of the
approved type) if you need to get your water supply from public piping.
•
When using copper piping for the water supply connections, replace the included half-union joints.
(Refer to Fig. 9)
•
Use two spanners when attaching or removing pipes to the half-union joints.
•
Secure the water supply piping without applying pressure.
