Before Test Run - Mitsubishi Electric GUG-01SL-E Installationsanleitung

Test run

Before test run

► After completing installation and the wiring and piping of the indoor
and outdoor units, check for refrigerant leakage, looseness in the
power supply or control wiring, wrong polarity, and no disconnection
of one phase in the supply.
► Use a 500-volt megohmmeter to check that the resistance between
the power supply terminals and ground is at least 1.0 MΩ.
► Do not carry out this test on the control wiring (low voltage circuit)
terminals.
Test run
■ Make sure to read operation manual before test run. (Especially items to secure safety)
Step 1 Turn on the power.
● Remote controller: The system will go into startup mode, and the remote controller power lamp (green) and "PLEASE WAIT" will blink. While
the lamp and message are blinking, the remote controller cannot be operated. Wait until "PLEASE WAIT" is not displayed before operating the
remote controller. After the power is turned on, "PLEASE WAIT" will be displayed for approximately 2 minutes.
● PCB A of Dx-coil unit: LED 1 will be lit up, LED 2 will be lit up or off, and LED 3 will blink.
● Outdoor controller board: LED 1 (green) and LED 2 (red) will be lit up. (After the startup mode of the system finishes, LED 2 will be turned off.) If
the outdoor controller board uses a digital display, [- ] and [ -] will be displayed alternately every second.
If the operations do not function correctly after the procedures in step 4 and thereafter are performed, the following causes should be considered
and eliminated if they are found.
(The symptoms below occur during the test run mode. "Startup" in the table means the LED display written above.)
● When the system of Lossnay unit and Dx-coil unit is in M-NET, please wait until M-NET system is ready to use.
Remote Controller Display
Remote controller displays "PLEASE
WAIT", and cannot be operated.
After power is turned on, "PLEASE WAIT"
is displayed for 3 minutes, then error code
is displayed.
No display appears even when remote
controller operation switch is turned on.
(Operation lamp does not light up.)
Display appears but soon disappears
even when remote controller is operated.
Step 2 Lossnay unit test run
Please refer to the installation manual of Lossnay unit for the test run.
Step 3 Drain pump test run
Please refer to page 10.
Step 4 Switch the remote controller (PZ-01RC) to "Test run".
1 Select "Test run" from the Service menu, and press the [SELECT]
button. (Fig. 1)
2 Select "Test run" from the Test run menu, and press the [SELECT]
button. (Fig. 2)
3 The test run operation starts, and the Test run operation screen is
displayed.
Note;
(1) When Lossnay unit fan speed is 1 or 2, Dx-coil unit will NOT be
thermo-ON. Please select fan speed 3 or 4 from remote controller
or other method.
(2) When the OA temperature (Lossnay thermistor) is less than -10˚C,
Dx-coil unit may NOT be thermo-ON because of the intermittent
operation.
(3) When Dx-coil unit does not become thermo-ON, please wait for 10
minutes. Dx-coil unit keeps compressor OFF for at least 10 minutes
for protection reason.

WARNING:
• Do not use the Dx-coil unit if the insulation resistance is less
than 1.0 MΩ.
• Turn on the power at least 12 hours before starting operation.
- Starting operation immediately after turning on the main power
switch can result in severe damage to internal parts. Keep the power
switch turned on during the operational season.
• After power is turned on, "PLEASE WAIT" is
displayed for 2 minutes during system startup.
