Test Run Manual
2 How to Perform a Test Run
Test Run Procedure
After the completion of the installation, piping and wiring works, implement the test run according to the
procedure below.
Confirm this prior to the test run. (Review the installation and test run check sheets attached.)
(1)
Verify that the outdoor, indoor, and BS units have been correctly configured.
(2)
(3) Turn on the power for the indoor, outdoor, and BS units, confirm transmission signal for indoor and outdoor units and open the fuel gas cock.
(For the test run, more than 6 hours of energizing is required for the outdoor unit.)
(4) Use the PCB checker on the main PCB of the outdoor unit and check
the operation of the actuator. Refer to "How to use the PCB checker".
(5)
CAUTION
(6)
The refrigerant has been filled as indicated
in the installation and piping manual.
(7)
Fully open the stop valves of outdoor unit

discharge) sides.
Install the accessory stoppers to the stop
valves. (GYEQ20AN valves are intake gas
side stop valves; GYEQ30AN only the stop
valves on the discharge gas side)

(11) The test run should start with the cooling operation, then change to the heating operation. *
(12) The test run should be implemented during normal operation (the total operated hours should be displayed on the hour meter; however,
when connecting the PC checker, "Option" should be displayed), check each function and measure operation data to confirm normal
operation.
(Checked items should be recorded in accordance with the test run check sheet attached. Data obtained via the PC checker should be
added to the check sheet.)
* When unable to operate the system due to indoor and outdoor temperature condition, do a test run by setting the remote controller to
test run mode and the outdoor unit to the checker mode. To set the checker mode of the outdoor unit, turn on the checker mode on the
PC checker or the PCB checker.
maximum.
CAUTION: Operation may not be possible for 30 minutes after powering the unit.
minutes in protection mode after starting. The operation may be stopped automatically, but the unit will also switch back to
normal operation automatically.

Confirm the filling method of the additionally filled refrigerant. The test run procedures vary according to the filling method.
Make sure that more than six hours have elapsed after energizing. Otherwise the compressor may be damaged.
The refrigerant has been filled by other methods than indicated in the installation and
piping manual. Or the filling method is not known. (Unknown)
When both intake and discharge stop
valves are closed
Open the liquid side stop valve only.
Go into the "Refrigerant Misfilling Emergency Mode". Refer to the next page.

Connect the PC checker to the main PCB of the outdoor unit and
or
check the operation of the actuator.
When the gas stop valves (intake and
discharge) are opened
Leave for more than 24 hours after the power
has been turned on.
(This is to maintain the heater welding time.)
Close the gas stop valves (intake and
discharge).
(The liquid side stop valve opens.)
