Add refrigerant
The equipment contains a basic
quantity of refrigerant. Extra
refrigerant must be added if the
basic length of the refrigerant
pipes exceeds 5 metres. Refer to
the following table:
After the tightness check has
been successfully completed,
connect the vacuum pump via
the pressure gauge station to
the valve connections on the
outdoor component (see chapter
"Tightness check") and create a
vacuum.
Perform the following checks
prior to commissioning the
unit for the first time and after
Before
commissioning
Wear protective clothing when
handling refrigerant.
CAUTION
NOTE
Check the overheating to
determine the refrigerant fill

any interventions affecting the
refrigerant circuit. Record the
results in the commissioning
report:
■
Check all refrigerant pipes and
valves using leak detection
spray or soapy water to ensure
they are tight and that the
suction and injection pipes
are not accidentally mixed up.
Perform this check when the
unit is not running .
■
Check the refrigerant pipes and
insulation for signs of damage.
■
Check the electrical connections
between the indoor unit and
outdoor component to verify
the correct polarity.
■
Check that all fastenings,
mountings etc. are firm and at
the correct level.
