INFORMATION
▪ When a malfunction is detected during the procedure
(e.g., in case of closed stop valve), a malfunction code
will be displayed. In that case, refer to
codes when charging refrigerant" on page 16
solve the malfunction accordingly. Resetting the
malfunction can be done by pushing BS3. You can
restart the "Charging" instructions.
▪ Aborting the manual refrigerant charge is possible by
pushing BS3. The unit will stop and return to idle
condition.
10 Open valve A.
11 Charge refrigerant until the remaining determined additional
refrigerant amount is added, and then close valve A.
12 Press BS3 to stop the manual additional refrigerant charge
mode.
NOTICE
Make sure to open all stop valves after (pre-) charging the
refrigerant.
Operating with the stop valves closed will damage the
compressor.
