Add refrigerant
The unit contains a basic quantity of refrigerant. Additional refrigerant
may be required depending on the indoor unit used.
The revised refrigerant quantities are given in the following table:
Note that the employed
refrigerant is always filled in
liquid form!
CAUTION
Commissioning
The system can be commissioned
once all the components have
been connected and tested.
A functional check should be
performed to verify its correct
function and identify any unusual
operational behaviour prior to
handing it over to the operator.
This check is dependent on the
installed indoor unit.
The procedures are specified in the
manual for the indoor unit being
commissioned.
Function test and test run
Check the following points:
■
Leak tightness of refrigerant
pipes.
■
Compressor and fan running
smoothly.
■
In cooling mode, cold air should
be output by the indoor unit,
and warm air should be output
by the outdoor component.
