Before commissioning
After successful leakage test, the
vacuum pump must be connected
using the pressure gauge station
to the valve connections of
the outdoor unit (see chapter
"Leakage test") to create
a vacuum.
Perform the following checks
prior to commissioning the
unit for the first time and after
Add refrigerant
The equipment contains a
basic quantity of refrigerant.
Furthermore, for refrigerant line
lengths of more than 5 metres
per circuit, an additional amount
of refrigerant must be added,
in accordance with the following
chart:

any interventions affecting the
refrigerant circuit. Record the
results in the commissioning
report:
■
Check all refrigerant lines and
valves with leak detection spray
or soapy water for leaks and for
inadvertent mix up of suction
and injection line. Perform this
check when the unit is not
running.
■
Check the refrigerant lines and
insulation for damage.
■
Check the electrical connection
between the indoor unit and
the outdoor unit for correct
polarity.
■
Check that all fastenings,
mountings etc. are firm and
at the correct level.
Wear protective clothing when
handling refrigerant.
