Electric Wiring Work - Daikin FCQ18PVJU Installation Manual

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
additional force.
Drain hose (1) (accessory)
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.
(2) After piping work is fi nished, check if drainage fl ows
smoothly.
• Open the water inlet lid, add approximately 37 in³ of
water slowly and check drainage fl ow.
WHEN ELECTRIC WIRING WORK IS FINISHED
• Check drainage fl ow during COOL running, explained under
"TEST OPERATION".
WHEN ELECTRIC WIRING WORK IS NOT FINISHED
• Remove the control box lids, connect a power supply wire and
remote controller wire to the terminals.

ELECTRIC WIRING WORK

9-1 GENERAL INSTRUCTIONS
• All fi eld 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
• Do not ground units to water pipes, telephone wires or
lightning 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 explo-
sion which could lead to severe injury or death.
