Test Operation
ESIE15-13C
58
Field Setting
1. Test 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.
Never perform a test run with the discharge piping thermistor (R2T) and suction piping
thermistor (R3T) removed, as this might break the compressor.
Do not touch the drain pump or fan if the indoor unit is operated without attaching the decoration
panel. (Doing so could result in an electric shock or other injury.)
Note:
Note that during the first running period of the unit, required power input may be higher. This
phenomenon originates from the compressor that requires a 50-hour run-in period before
reaching smooth operation and stable power consumption.
1.1
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.
1.2
Remote Controller Confirmation
• The settings of the remote controller for the BRC1D series should be made in accordance
with the following procedure.
• The settings of the remote controller for the BRC1E series should be made in accordance
with the attached manual.
Items to check
Electrical wiring
Inter-unit wiring
Earth 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
Ω
?
- 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?
Indoor unit
Is the indoor unit fully installed?
- When the test run is started, the fan automatically begins turning.
If a decoration panel is not attached, make sure that no work is being done
on the indoor unit.
- If you are using the wireless remote controller, do the test run after
attaching the decoration panel to the indoor unit.
