When cables are routed from the unit, a protection sleeve for the
conduits (PG-insertions) can be inserted at the knock-out hole.

When you do not use a wire conduit, be sure to protect the wires
with vinyl tubes to prevent the edge of the knock-out hole from
cutting the wires.

Follow the electric wiring diagram for electrical wiring works.

Form the wires and fix the cover firmly so that the cover may be
fit in properly.

Precautions on wiring of power supply and inter-unit 
wiring

Use a round crimp-style terminal for
connection to the power supply
terminal board. In case it cannot be
used due to unavoidable reasons,
be sure to observe the following
instruction.
-

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

-

When connecting wires of the same gauge, connect them 
according to the below figure.

Use the correct screwdriver to tighten the terminal screws.
Small screwdrivers can damage the screw head and prevent
appropriate tightening.

Over-tightening the terminal screws can damage the screws.

See the tabel below for tightening torques for the terminal
screws.

Refer to the installation manual attached to the indoor unit for
wiring of indoor units, etc.

Attach an earth leak detector and fuse to the power supply line.

(See figure 8)

In wiring, make certain that prescribed wires are used, carry out
complete connections, and fix the wires so that outside forces
are not applied to the terminals.

OPERATION

Be sure to fully open the liquid-side and gas-side stop valves.

For details on test operation, refer to the indoor unit installation
manual.

Pre-run checks

Test run

1

Make sure the liquid and gas shut-off valves are open.

Be sure to close the frontside panel before operation, as not
doing so can cause electric shock.
-

The refrigerant pressure may not rise, even if the shut-off 
valve is opened after an air purge is performed using a 
vacuum pump.
This is because the indoor unit refrigerant piping is closed off
with electric valves inside. This will not create any problems
during operation.

2

Be sure to set it to cooling and press the operation switch.

3

Press the inspection/test-run switch on the remote control to put
the machine into test-run mode.

4

Make sure the compressor is not starting and stopping during
the test-run by listening. If it is starting and stopping,
immediately stop the machine using the remote control, and
check the refrigerant level, etc. There may be some sort of
malfunction.

Items to check

Electrical wiring
Inter-unit wiring
Ground wire

Is the wiring as mentioned on the wiring
diagram?
Make sure no wiring has been forgotten and that
there are no missing phases or reverse phases.

Is the unit properly grounded?

Are any of the wiring attachment screws loose?

Refrigerant piping

Is the size of the piping appropriate?

Is the insulation material for the piping attached
securely?
Are both the liquid and gas pipes insulated?

Are the shut-off valves for both the liquid side and
the gas side open?

Extra refrigerant

Did you write down the extra refrigerant and the
refrigerant piping length?
