could lead to leaks.)

• Where corrosive gas like sulfurous gas exists. (Cop-

per tubing and brazed spots may corrode which could
eventually lead to refrigerant leaks.)

• Where exposed to combustible gases and where vol-

atile flammable gas like thinner or gasoline is used.
(Gas in the vicinity of the unit could ignite.)

• Where machines can generate electromagnetic

waves. (Control system may malfunction.)

CAUTION

Be sure to insulate any field piping all the way to the piping
connection inside the unit. Any exposed piping may cause
condensation or burns if touched.

CAUTION

CAUTION TO BE TAKEN WHEN BRAZING REFRIGER­ANT PIPING

Do not use flux when brazing refrigerant piping. Therefore,
use the phosphor copper brazing filter metal (BCuP) which
does not require flux.
(Flux has extremely harmful infulence on refrigerant piping
sysems. For instance, if the chlorine based flux is used, it will
cause pipe corrosion or, in particular, if the flux contains fluo­rine, it will damage the refrigerant oil.)

• Before brazing local refrigerant piping, nitrogen gas shall be
blown through the piping to expel air from the piping.
If your brazing is done without nitrogen gas blowing, a large
amount of oxide film develops inside the piping, and could
cause system malfunction.

• When brazing the refrigerant piping, only begin brazing after
having carried out nitrogen substitution or while inserting
nitrogen into the refrigerant piping. Once this is done, con­nect the indoor unit with a flared or a flanged connection.

• Nitrogen should be set to 0.02 Mpa (0.2 kg/cm
sure-reducing valve if brazing while inserting nitrogen into
the piping.

CAUTION

Over-tightening may damage the flare and cause a refriger­ant leakage.

Use “ Ta b el 4 ” as a reference if a torque wrench is not available.
Once work is complete, make sure there is no gas leaking. As
the flare nut is tightened with the wrench, the torque will sud­denly increase. From that position, tighten the nut to the angle
shown on “ Tab el 4 ”.

• Make absolutely sure to execute heat insulation works on the
pipe-connecting section after checking gas leakage by thor­oughly studying the following figure and using the attached
heat insulating materials for fitting. (Fasten both ends with
the clamps (accessory).)

• You can temporarily hang the electric parts box of the unit
from the position shown in the figure below. Use according to
the type of work.

CAUTION

• Be sure to attach the sealing material or putty (field supplied)
to hole of wiring to prevent the infiltration of water as well as
any insects and other small creatures from outside. Other­wise a short-circuit may occur inside the electric parts box.

• When clamping the wires, be sure no pressure is applied to
the wire connections by using the included clamping material
to make appropriate clamps. Also, when wiring, make sure
the lid on the electric parts box lid fits snugly by arranging the
wires neatly and attaching the electric parts box lid firmly.
When attaching the electric parts box lid, make sure no wires
get caught in the edges. Pass wiring through the wiring
through holes to prevent damage to them.

• Make sure the remote controller wiring, the wiring between
the units, and other electrical wiring do not pass through the
same locations outside of the unit, separating them by at
least 50mm, otherwise electrical noise (external static) could
cause mistaken operation or breakage.

[ PRECAUTIONS ]

1. Use round crimp-style terminals for connecting wires to the

power supply terminal board.
If unavailable, observe the following points when wiring.

• Do not connect wires of different gauge to the same
power supply terminal.
(Looseness in the connection may cause overheating.)

• Use the specified electric wire. Connect the wire securely
to the terminal. Lock the wire down without applying
excessive force to the terminal. (Tightening torque:

131N·cm ±10 %)

Attach insulation sleeve

Round crimp-style terminal

Electric wire

2. Tightening torque for the terminal screws.

• Use the correct screwdriver for tightening the terminal
screws. If the blade of screwdriver is too small, the head
of the screw might be damaged, and the screw will not be
properly tightened.

• If the terminal screws are tightened too hard, screws
might be damaged.

• Refer to the table below for the tightening torque of the
terminal screws.

Terminal Size Tightening torque

Terminal block for remote controller (6P) M3.5 0.79 – 0.97N·m

Power supply terminal block (2P) M4 1.18 – 1.44N·m

Ground terminal M4 1.44 – 1.94N·m

3. Do not connect wires of different gauge to the same ground­ing terminal. Looseness in the connection may deteriorate
protection.

4. Out side of the unit, keep transmission wiring at least 50 mm
away from power supply wiring. The equipment may mal­function if subjected to electrical (external) noise.

5. For remote controller wiring, refer to the “INSTALLATION
MANUAL OF REMOTE CONTROLLER” attached to the
remote controller.

6. Never connect power supply wiring to the terminal

block for remote controller wiring. A mistake of the sort
could damage the entire system.

7. Use only specified wire and tightly connect wires to termi­nals. Be careful wires do not place external stress on termi­nals. Keep wiring in neat order and so as not to obstruct
other equipment such as popping open the electric parts
box lid. Make sure the lid closes tight. Incomplete connec­tions could result in overheating, and in worse case, electric
shock or fire.
