(2) Check to make sure the water flows smoothly after pip-
ing is complete.
• Slowly pour 600ml of drain-checking water into the drain pan
through the air outlet.
CAUTION
• Keep in mind that it will become the cause of getting drain
pipe blocked if water collects on drain pipe.
8. ELECTRIC WIRING WORK
8-1 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 control box lid.
• For remote controller wiring details, refer to the installation
manual attached to the remote controller.
• All wires 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 wire and pipe between the outdoor unit and an indoor unit
are mismatched, the system may cause a malfunction.
• An earth leakage 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.
DANGER
• Do not ground units to water pipes, telephone wires or light-
ning rods because incomplete grounding could cause a
severe shock hazard resulting in severe injury or death, and
to gas pipes because a gas leak could result in an explosion
which could lead to severe injury or death.

9. WIRING EXAMPLE AND HOW TO SET
THE REMOTE CONTROLLER
9-1 HOW TO CONNECT WIRES
CAUTION
• Even if the control box lid is removed, pull the remote control-
ler wire, transmission wire and the power supply wire inside
the unit using conduits for each, so that the wires do not come
into contact with the opening section of the metal casing.
• Pass conduits through the wall and secure along with the
refrigerant pipe in order to prevent external pressure being
applied to transmission wire and power supply wire.
• Prevent dust from entering into the unit by filling the gap
around the pipe, wire with corking or putty.
• Arrange the wires and fix a lid firmly so that the lid does not
float during wiring work.
• Do not clamp remote controller wire and transmission wire
together with power supply wire. Doing so may cause mal-
function.
• Remote controller wire, transmission wire and power supply
wire should be located at least 5 in. from other electric wires.
Not following this guideline may result in malfunction due to
electrical noise.
<Method of wiring power supply, units and connecting
remote controller wiring> (Refer to Fig. 27)
