OPERATION

Be sure to fully open the liquid-side and gas-side stop valves.

For details on test operation, refer to the indoor unit installation
manual.

Pre-run checks

Test run

1

Make sure the liquid and gas shut-off valves are open.

Be sure to close the frontside panel before operation, as not
doing so can cause electric shock.
-

The refrigerant pressure may not rise, even if the shut-off 
valve is opened after an air purge is performed using a 
vacuum pump.
This is because the indoor unit refrigerant piping is closed off
with electric valves inside. This will not create any problems
during operation.

2

Be sure to set it to cooling and press the operation switch.

3

Press the inspection/test-run switch on the remote control to put
the machine into test-run mode.

4

Make sure the compressor is not starting and stopping during
the test-run by listening. If it is starting and stopping,
immediately stop the machine using the remote controller, and
check the refrigerant level, etc. There may be some sort of
malfunction.

5

At first test-run of the unit, the valves are checked if they are not
closed. Therefore the unit starts in cooling mode (even if the
remote controller is set to heating mode) for about 2-3 minutes
and then switches automatically to heating mode. The remote
controller will always display heating mode.

Precautions regarding test-runs

If the remote control shows E0, E3 or E4 as an error code, there
is a possibility that either the shut-off valve is closed, or the
outlet vent is closed.

For a reverse phase in case of W1 units, U1 will be displayed on
the remote controller of the indoor unit. 
For a missing phase in case of W1 units, E0 or E6 will be
displayed on the remote controller of the indoor unit.
Operation will be impossible with either one of these
phenomena. If this happens, turn off the power, re-check the
wiring and switch the position of two of the three electrical wires.
(If operation is not possible, do not under any circumstances
force the electromagnetic contactor on.)

If the error code E6 is displayed on the remote contoller, check
for voltage imbalance.

If the error code U4 or UF is displayed on the remote contoller,
check the inter-unit branch wiring connection.

Diagnosis

On the remote controller LCD
If the machine stops due to some malfunction, you can diagnose
the problem using the error code displayed on the remote
controller.

-

The malfunction code should be looked up in the installation 
manual for the indoor unit.

-

Depending on the indoor unit or outdoor unit type, error 
codes may not be displayed.

REQUIREMENTS

Dismantling of the unit, treatment of the refrigerant, of oil and of other parts
must be done in accordance with relevant local and national legislation.

Items to check

Electrical wiring
Inter-unit wiring
Ground 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?

Are any of the wiring attachment screws loose?

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 shut-off 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?
