CAUTION
• Fully open the shutoff valves on the liquid and gas sides
after the refrigerant replenishment is finished.
The compressor will malfunction if the system is operated with the
shutoff valves closed.
• Apply a screw lock agent to the screws of the valve cover
mounting parts and service ports.
(Otherwise, dew condensation water will intrude and freeze inside
and cause cap deformation or damage, which may result in refrig-
erant gas leakage or compressor malfunctions.)

11. TEST RUN

For test run operators
Do not operate the outdoor unit alone on a trial basis.
Test run procedure
Use the following procedure to perform a test run after installation
work is complete for the entire system:
1.
Fully open the shutoff valves on the gas and liquid sides of the
outdoor unit.
2.
Set the RUN switch of the outdoor switch to ON.
Note: Before turning power on, check that the piping cover and
control box lid of the outdoor unit are closed.
3.
Check the sealing condition of the outdoor unit through the sight
glass. Make sure that the amount of refrigerant is sufficient.
4.
Make sure that cold air blows from the indoor unit.
Check that the internal temperature is dropping.
(Check that the temperature will drop and reach the set tempera-
ture in the internal unit. It will take approximately 40 minutes for
the interior temperature of the internal unit to reach –20°C.)
Check that the indoor unit (for refrigeration or freezing) goes into
defrosting operation.
5.
Turn power off with the RUN switch of the outdoor unit set to OFF.
(Stopping unit operation by disconnecting the power supply
directly is dangerous. When the unit is stopped in this manner, its
power outage compensation function may cause it to resume
operation as soon as the power supply is reactivated. Additionally,
stopping the unit in this manner may cause the compressor to
fail).

Set the operating switch to the "OFF" position to reset the power sup-
ply and then return the switch to the "ON" position to restart the unit.
If the problem persists, refer to the Service Manual.
• If the system cannot operate normal at the time of test run (i.e.,
the H2P indicator is lit), check with malfunction code on the sys-
tem with the pushbutton switches on the PCB of the outdoor unit,
and take the following steps.
• Make checks on other malfunction codes and pushbutton
switches by referring to the provided Technical Guide.

CAUTION
• Do not disconnect the power supply for 1 minute after setting the
operating switch to "ON".
Electric leak detection is performed for several seconds after the
operating switch is set to "ON" and each compressor starts oper-
ating, so disconnecting the power supply during that time will
result in a false detection.
For dealers
• After the test run is finished, check that the piping cover and front
panel are mounted.
• At the time of delivery to the customer, use the Operation Manual
and fully explain the handling of the equipment.
• For precautions at the time of delivery, refer to the provided Instal-
lation Manual for each unit as well.
