INFORMATION
If the total additional refrigerant amount was reached in
step 3 (by pre-charging only), record the amount of
refrigerant that was added on the additional refrigerant
charge label provided with the unit and attach it on the
back side of the front panel.
Perform the test procedure as described in
"8Commissioning"on page38.
Charging refrigerant
5 After pre-charging, connect valve A to the refrigerant charge
port and charge the remaining additional refrigerant through this
port. Open all outdoor unit stop valves. At this point, valve A
must remain closed!

INFORMATION
For a multi outdoor unit system, it is not required to
connect all charge ports to a refrigerant tank.
The refrigerant will be charged with ±22 kg in 1 hour time
at an outdoor temperature of 30°CDB or with ±6kg at an
outdoor temperature of 0°CDB.
If you need to speed up in case of a multiple outdoor
system, connect the refrigerant tanks to each outdoor unit.
NOTICE
▪ The refrigerant charging port is connected to the piping
inside the unit. The unit's internal piping is already
factory charged with refrigerant, so be careful when
connecting the charge hose.
▪ After adding the refrigerant, do not forget to close the
lid of the refrigerant charging port. The tightening
torque for the lid is 11.5 to 13.9N•m.
▪ In order to ensure uniform refrigerant distribution, it
may take the compressor ±10 minutes to start up after
the unit has started operation. This is not a malfunction.
6 Proceed with the manual charge.
INFORMATION
After charging refrigerant:
▪ Record the additional refrigerant amount on the
refrigerant label provided with the unit and attach it to
the backside of the front panel.
▪ Perform the test procedure described in
"8Commissioning"on page38.
6.7.6 Step 6: To manually charge refrigerant
The remaining additional refrigerant charge can be charged by
operating the outdoor unit by means of the manual refrigerant
charge operation mode:
1 Take all the precautions mentioned in "7 Configuration" on
page30 and "8Commissioning"on page38 into account.
2 Turn on the power of the indoor units and outdoor unit.
3 Activate outdoor unit setting [2‑20]=1 to start manual refrigerant
charge mode. Refer to "7.2.8 Mode 2: Field settings" on
page33 for details.
Result: The unit will start operation.
4 Valve A can be opened. Charging of remaining additional
refrigerant can be done.
5 When the remaining calculated additional refrigerant amount is
added, close valve A and push BS3 to stop the manual
refrigerant charging procedure.
INFORMATION
The manual refrigerant charge operation will automatically
stop within 30 minutes. If charging is not completed after
30 minutes, perform the additional refrigerant charging
operation again.
6 Perform the test procedure as described in
"8Commissioning"on page38.
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 "6.7.7 Error
codes when charging refrigerant" on page 26 and
solve the malfunction accordingly. Resetting the
malfunction can be done by pushing BS3. The
procedure can be restarted from "6.7.6 Step 6: To
manually charge refrigerant"on page26.
▪ Aborting the manual refrigerant charge is possible by
pushing BS3. The unit will stop and return to idle
condition.
6.7.7 Error codes when charging refrigerant
If a malfunction occurs, close valve A immediately. Confirm the
malfunction code and take corresponding action, "10.2 Solving
problems based on error codes"on page40.
6.7.8 Checks after charging refrigerant
▪ Are all stop valves open?
▪ Is the amount of refrigerant, that has been added, recorded on the
refrigerant charge label?
NOTICE
Make sure to open all stop valves after (pre-) charging the
refrigerant.
Operating with the stop valves closed will damage the
compressor.
6.8 Connecting the electrical wiring
6.8.1 Precautions when connecting electrical
wiring
DANGER: RISK OF ELECTROCUTION
WARNING
All field wiring and components must be installed by a
licensed electrician and must comply with the applicable
legislation.
WARNING
If NOT factory installed, a main switch or other means for
disconnection, having a contact separation in all poles
providing full disconnection under overvoltage categoryIII
condition, shall be installed in the fixed wiring.
