10.3.   Specifications of standard wiring 

components

       

CAUTION

„

 

Select all cables and wire sizes in 

accordance with applicable legislation.

„

 

After finishing the electrical work, confirm 

that each electric part and terminal inside the 

electric part box is connected securely.

„

 

The earth leakage breaker must be a high-

speed type breakerof 30 mA(<0.1 s).

11. Test

 

operation

        

DANGER

Never leave the unit unattended during installation or 

servicing. When the service panel is removed live 

parts can be easily touched by accident.

        

INFORMATION

Note that during the first running period ofthe unit, 

required power input may be higher 

than stated on 

the nameplate ofthe 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.

11.1. Pre-run checks

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?

 

„

Is the wiring between units connected 

in series correct?

Are any of the wiring attachment 

screws loose?

Is the insulation resistance at leaset 1 MΩ?

-  Use a 500V mege-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 compressorwill breakdown.

 

„

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.

11.2.  Precautions regarding test-runs

1.

In order to detect stop valves failing to open,

operation ofthe unit is compulsorily performed in

cooling for 2-3 minutes during the first test run,

 

even

ifthe remote controller was set to heating

 

operation.

In this case, the remote controllerwill have

keptdisplaying the heating symbol all the time and

 

the

unit will switch to heating operation automatically

after elapse of that time.

2.

In case you cannot operate the unit in test run

 

mode

for any unusual reason, refer to "11.4. Failure

diagnosis at the moment offirst installation"

.

3.

In case of a wireless remote controller, execute

the run only after having installed the indoor unit

decoration panel with infrared receiverfirst.

4.

In case the panels of indoor units are not yet installed

to the indoor units, make sure to shut off the power

supply after finishing the complete test run.

5.

A complete test run surely includes shutting off power

after having performed a normal operation stop

on the remote controller. Do not stop operation by

turning circuit breakers off.
