[ WHEN ELECTRIC WIRING WORK IS NOT FINISHED ]
• Remove the electric parts box lid, connect a power supply
and remote controller to the terminals.
(Refer to the “HOW TO CONNECT WIRINGS”)
Be sure attach the electric parts box lid before turning on the
power.
Next, press the inspection/test operation button “
” on the
remote controller. The unit will engage the test operation
mode. Press the operation mode selector button “
” until
selecting FAN OPERATION “
”. Then, press the ON/OFF
button “
”. The indoor unit fan and drain pump will start up.
Check that the water has drained from the unit. Press “
”
to go back to the first mode.
•
Be careful when doing so because the fan is turning at
the same time.
• Attach the electric parts box lid as before.
CAUTION
• 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 pipes and corrode the heat
exchanger.
• Keep in mind that it will become the cause of getting drain
pipe blocked if water collects on drain pipe.

GENERAL INSTRUCTIONS
• All field supplied parts and materials and electric works must
conform to local codes.
• Use copper wire only.
• For electric wiring work, refer to also
“
Wiring diagram label
”
attached to the electric parts box lid.
• For remote controller wiring details, refer to the installation
manual attached to the remote controller.
• All wiring must be performed by an authorized electrician.
• This system consists of multiple indoor units. Mark each
indoor unit as unit A, unit B..., and be sure the terminal board
wiring to the outdoor unit and BS unit are properly matched.
If wiring and piping between the outdoor unit and an indoor
unit are mismatched, the system may cause a malfunction.
• A circuit breaker capable of shutting down power supply to
the entire system must be installed.
• Refer to the installation manual attached to the outdoor unit
for the size of power supply wiring connected to the outdoor
unit, the capacity of the circuit breaker and switch, and wiring
instructions.
• Be sure to ground the air conditioner.
• Do not connect the ground wire to gas and water pipes, light-
ning rods, or telephone ground wires.
• Gas pipes
:
might
cause explosions or fire if gas leaks.
• Water pipes : no grounding effect if hard vinyl piping is
used.
• Telephone ground wires or lightning rods : might cause
abnormally high electric potential in the ground during
lighting storms.
