Installation manual

15. Test operation

15.1. Pre-run checks

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.

15.2. Remote controller confirmation

The settings of the remote controller for the BRC1E52 series 
should be made in accordance with procedure 

15.3.

The settings of the remote controller for the BRC1E51 series 
should be made in accordance with the procedure mentioned in 
the remote controller installation manual.

The settings of the remote controller for the BRC1D series 
should be made in accordance with the procedure mentioned in 
the service manual.

15.3. Test run

1

Be sure to turn power on at least 6 hours before starting 
operation in order to protect the compressor.

2

Make sure the liquid and gas stop valves are open.

3

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

4

Be sure to set the unit to cooling operation mode.

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 of the unit, 
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.

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 least 1 M

?

- 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?
