NOTE
• The incline of attached drain hose (1) should be 2 15/16 in. or
less so that the drain socket does not have to stand addi-
tional force.
Select converging drain pipe whose gauge is suitable for the
operating capacity of the unit.
• Drain pipe connections
Do not connect the drain pipe directly to sewage pipes that
smell of ammonia. The ammonia in the sewage might enter
the indoor unit through the drain pipe 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.

• All field supplied parts and materials, electric works must
conform to local codes.
• Use copper wire only.
• Follow the “WIRING DIAGRAM” attached to the unit body to
wire the outdoor unit, indoor unit and the remote controller.
For details on hooking up the remote controller, refer to the
“INSTALLATION MANUAL OF REMOTE CONTROLLER”.
• All wires must be performed by an authorized electrician.
• A circuit breaker capable of shutting down the power supply
to the entire system must be installed.
• Be sure to ground the air conditioner.
DANGER

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.
