9. ELECTRIC WIRING WORK
9-1 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 fir e.
•
Make sure to install an earth leakage breaker.
Failure to do so may cause electric shocks and a
fir e.
• 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 wire 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.

8. DUCT WORK
Pay the utmost attention to the following items and
conduct the ductwork.
• Check that the duct is not in excess of the setting range of
external static pressure for the unit. (Refer to the technical
datasheet for the setting range.)
• Attach a canvas duct each to the air outlet and air inlet so
that the vibration of the equipment will not be transmitted to
the duct or ceiling.
Use a sound-absorbing material (insulation material) for the
lining of the duct and apply vibration insulation rubber to the
hanging bolts.
•
At the time of duct welding, perform the curing of the duct so
that the sputter will not come in contact with the drain pan for
the
filte r.
•
If the metal duct passes through a metal lath, wire lath, or
plate of a wooden structure, separate the duct and wall
electrically.
•
Be sure to heat insulate the duct for the prevention of
dew condensation. (Material: Glass wool or styrene foam;
Thickness: 25 mm)
•
Be sure to attach the field supply air filter to the air inlet of the
unit or field supply inlet in the air passage on the air suction
side. (Be sure to select an air filter with a duct collection
efficiency of 50 weight percent.)
• Explain the operation and washing methods of the locally
procured components (i.e., the air
filte r, air inlet grille, and air
outlet grille) to the customer.
• Locate the air outlet grille on the indoor side for the
prevention of drafts in a position where indirect contact with
people.
• The air conditioner incorporates a function to adjust the fan
to rated speed automatically.
(10. FIELD SETTING)
Therefore, do not use booster fans midway in the duct.
Connection method of ducts on air inlet and outlet sides.
•
Connect the field supply duct in alignment with the inner side
of the flang e.
• Connect the flange and unit with the flange connection screw (3).
• Wrap aluminum tape around the flange and duct joint in
order to prevent air leakage.
