Perform the test procedure as described in

"20 Commissioning"

[

145].

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

"17.4.8 Error

codes when charging refrigerant"

[

107] and solve the malfunction accordingly.

Resetting the malfunction can be done by pushing BS3. The procedure can be
restarted from

"17.4.7 Step 6b: To manually charge refrigerant"

[

106].

▪

Aborting the manual refrigerant charge is possible by pushing BS3. The unit will
stop and return to idle condition.

17.4.8 Error codes when charging refrigerant

Code

Cause

Solution

Unusual low pressure on
suction line

Close valve A immediately. Push
BS3 to reset. Check following
items before retrying
autocharge procedure:

▪

Check if the gas side stop
valve is opened correctly.

▪

Check if the valve of the
refrigerant

cylinder

opened.

▪

Check if the air inlet and
outlet of the indoor unit are
not obstructed.

Freeze-up prevention indoor
unit

Close valve A immediately. Push
BS3 to reset. Retry autocharge
procedure.

Indoor unit is out of
temperature range for leak
detection operation

Retry when ambient conditions
are satisfied.

Outdoor unit is out of
temperature range for leak
detection operation

Retry when ambient conditions
are satisfied.

Indicates an indoor unit which
is not compatible with leak
detection functionality is
installed (e.g., RA DX indoor
unit, Hydrobox, …)

Refer to requirements to be
able to execute leak detection
operation.

Other

malfunction

code

—

Close valve A immediately.
Confirm the malfunction code
and take corresponding action,

"23.1 Solving problems based
on error codes"

17.4.9 Checks after charging refrigerant

▪

Are all stop valves open?

▪

Is the amount of refrigerant, that has been added, recorded on the refrigerant
charge label?
