Electric Wiring Work - Daikin FXFQ25SVM Installation Manual

• Do not connect the drain piping directly to the sew-
age that gives off ammonia odor.
The ammonia in the sewage may go through the
drain piping and corrode the heat exchanger of the
indoor unit.
• Do not apply external force to the float switch. (It
may result in malfunction)
5. Turn off the power supply after checking drainage,
and remove the power supply wiring.
6. Attach the control box lid as before.
• Do not touch the electronic parts other than the
terminal block (X2M).
(3) Sweating may occur and result in water leakage.
Therefore, make sure to insulate the following 2 lo-
cations (drain piping and drain sockets that laid in-
doors).
After drainage is checked, put the attached sealing mate-
rial (14) referring to Fig. 20, and insulate the drain hose (1)
and the metal clamp (2) with the attached sealing material
(Large) (10) referring to Fig. 22.

Wrap the sealing material (Large) (10)
so that the metal clamp (2) end side
may be doubled.

8. ELECTRIC WIRING WORK

8-1 GENERAL INSTRUCTIONS
• Make certain that all electric wiring work is carried out by
qualified personnel according to the applicable legislation
and this installation manual, using a separate dedicated
circuit.
Insufficient capacity of the power supply circuit or improper
electrical construction may lead to electric shocks or a fire.
• Make sure to install an earth leakage breaker.
Failure to do so may cause electrical shocks and a fire.
• Do not turn on the power supply (branch switch, branch
overcurrent circuit breaker) until all the works are finished.
• Multiple number of indoor units are connected to one
outdoor unit. Name each indoor unit as A-unit, B-unit ..... and
the like. When these indoor units are wired to the outdoor unit
and the BS unit, always wiring the indoor unit to the terminal
indicated with the same symbol on the terminal block. If the
wiring and the piping are connected to the different indoor
units and operated, it will result in malfunction.

• Make sure to earth the air conditioner.
Earthing resistance should be according to applicable
legislation.
• Do not connect the earth wiring to gas or water pipings,
lightning conductor or telephone earth wiring.
• Gas piping .................Ignition or explosion may occur if
the gas leaks.
• Water piping ..............Hard vinyl tubes are not effective
earths.
• Lightning conductor or telephone earth wiring ..................
Electric potential may rise abnormally if struck by a light-
ning bolt.
• For electric wiring work, refer to also the "WIRING
DIAGRAM" attached to the control box lid.
• Carry out wiring between the outdoor units, indoor units and
the remote controllers according to the wiring diagram.
• Carry out installation and wiring of the remote controller
according to the "installation manual" attached to the remote
controller.
• Do not touch the Printed Circuit Board assembly. It may
cause malfunction.
