OUTDOOR UNIT TEST RUN
CAUTION: Always turn on the power 6 hours prior to the start of the operation in order to protect the compressor. Check items before performing the test run Make sure to perform the test run. Before performing the test run, be sure to check the following points.
- Is gas leaking? Check connection of each pipe (flare connection part, brazing part).
- Is a breaker installed to the power cable of the outdoor unit ?
- Has each cable been securely connected to the terminal according to the specifications ?
- Are the 3-way valves (gas pipes and liquid pipes) of the outdoor units open?
- Has the power been supplied to the unit for at least 6 hours ?
- Has the necessary local setting been done ?
- Check insulation resistance of 1 M or more using a 500V mega tester. If no problems are found with the above items, perform the test run according to “Test run method”. If any problems are found, immediately resolve the problem and re-check the items.
Test run method
CAUTION: If the test run is performed for 1 outdoor unit in a group control system installation, the test run will also be performed for the other units. Therefore, make sure that all of the units have been installed before starting a test run. (Group control system installation described in “SPECIAL INSTALLATION METHODS” in the installation manual of the indoor unit.) Operate [ENTER] (TEST RUN) switch on the display board by the following procedure.
Operating procedures for the test run
- Check the 3-way valves (both at the liquid side and gas side) are opened.
- Set the operation mode to “COOL” or “HEAT”.

SPECIAL INSTALLATION SETTING
OUTDOOR UNIT PUMP DOWN (Refrigerant collecting operation) Perform the following procedures to collect the refrigerant when moving the indoor unit or outdoor unit
WARNING:Never touch electrical components such as the terminal blocks or reactor except the switch on the display board. It may cause a serious accident such as electric shock.
CAUTION
- Perform the pump down operation before disconnecting any refrigerant pipe or electric cable.
- Collect refrigerant from the service port or the 3-way valve if pump down cannot be performed.
- In case of a group control system installation, do not turn the power off pump down is completed in all outdoor units.
- (Group control system installation described in “SPECIAL INSTALLATION METHODS” in the installation manual of the indoor unit.)
- Operate [PUMP DOWN] switch on the display board in the manner described below.
Preparation for pump down
Confirm that the power is off, and then open the service panel.
Pump down procedure
- Check the 3-way valves (both at the liquid side and gas side) are opened.
- Turn the power on.
