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 table 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 leakage breaker and fuse to the power supply
line. (See figure 9)

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.

EST OPERATION
WARNING
Live parts can be easily touched by accident.
Never leave the unit unattended during installation or
servicing when the service panel is removed.
Note that during the first running period of the unit,
NOTE
required power input may be higher than stated on the
nameplate of the unit. This phenomenon originates
from the compressor that needs elapse of a 50 hours
run in period before reaching smooth operation and
stable power consumption.
Pre-run checks
Items to check
Electrical wiring Is the wiring as mentioned on the wiring
Inter-unit wiring diagram?
Ground wire Make sure no wiring has been forgotten and that
there are no missing phases or reverse phases.
Is the unit properly grounded?
Is the wiring between units connected in series
correct?
Are any of the wiring attachment screws loose?
Is the insulation resistance at least 1 MΩ?
- Use a 500 V mega-tester when measuring
insulation.
- Do not use a mega-tester for low-voltage
circuits.
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 stop 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?
Be sure to perform a test run.
Be sure to fully open the liquid-side and gas-side stop valves. If
you operate the unit with stop valves closed, the compressor will
break down.
Be sure to execute the first test run of the installation in cooling
mode operation.
Never leave the unit unattended with an open front panel during
test run.
