• 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.
•An GROUND 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
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.
• To avoid short circuits in the electric parts box, be sure to apply
the sealing material or putty (not included) to the wiring hole to
prevent the infiltration of water, insects or other small creatures.
• 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
