The LED display must be as follows:
Press the button once as confirmation of the
LEDs combination.
LEDs will be blinking in function of the last entered setting
(factory setting = 0 kg).
4 The weighed and already recorded amount of additional
refrigerant charge (not the total amount of refrigerant present in
the system) must be entered by selecting the corresponding
LED display.
Scroll through the possible LED combinations by pressing the
button until the LED combination corresponds to the
weight of additional refrigerant charge you must input.
Select the required input by pressing the

charging operation when the display on the remote
controller is not showing

Close valve A immediately. Check
following items:
- Check if the high pressure/low
pressure gas pipe, suction gas pipe,
liquid pipes and equalizer pipe stop
valves are opened correctly
- Check if the valve of the refrigerant
cylinder is opened
- Check if the air inlet and outlet of the

stop
Close valve A immediately. Confirm the
malfunction code by the remote controller
and correct the abnormality by following
the
"Correcting after abnormal completion
of the test operation" on page 26 .
If a wrong value is inputted for the additional charged
refrigerant weight, the accuracy of the leak detection
function will decrease.
