single-phase, 60Hz 220V) respectively to the terminal block
and securely connect the earth also (as shown in the figure
below).
CAUTION
Securely clamp the cables with the clamps (9)(10) offered
as accessories as shown in Fig. 17 so that tension will not
be applied on the cable connection areas.
2. Confirm that the control box lid is closed before turning on
the power.
3. Remove the inspection lid.
4. Gradually pour approximately 1L of water from the
inspection window into the drain pan to check drainage.
CAUTION
Be sure to prevent an external force from being exerted on
the float switch.
(This may cause breakage.)
5. Attach the inspection lid.
6. Perform the following operation using the remote controller,

〈 PRECAUTIONS FOR DRAIN RAISING PIPE 〉
• Make sure the drain raising pipe height is no higher than
600 mm.
•
Place the drain raising pipe vertically and make sure it is no
further than 300 mm from the unit.
(Refer to Fig. 13)
〈 PRECAUTIONS 〉
Drain piping connections
• Do not connect the drain piping directly to sewage pipes that
smell of ammonia. The ammonia in the sewage might enter
the indoor unit through the drain piping and corrode the heat
exchanger.
• Do not twist or bend the drain hose (2), so that excessive
force is not applied to it.
(This type of treatment may cause leaking.)
• If you are using central drain piping, follow the procedure
outlined in the figure 10.
•
Select central drain piping of proper size according to the
capacity of the connected unit.
(2) After piping work is finished, check drainage flows
smoothly, with manner described below.
CAUTION
• The electric wiring work shall be performed by qualified
electricians.
• If workers not having the electrician qualification have
performed the electric wiring work, the steps 3 to 7 shall be
performed after the
TEST RUN

If there is an air bank, noise may be generated
as a result of a water backflow when the drain
pump comes to a stop.
Locate the drain hose horizontally
or with a little upward gradient.
