Before commissioning
After the tightness check has
been successfully completed,
connect the vacuum pump via the
pressure gauge station to the valve
connections on the outdoor unit
(see chapter "Tightness check")
and create a vacuum.
Perform the following checks
prior to commissioning the
unit for the first time and after
any interventions affecting the
refrigerant circuit. Record the
results in the commissioning
report:
■ Check of all refrigerant pipes
and valves with leak detection
spray or soapy water for leaks
and for inadvertent mix up of
suction and injection pipe, with
the unit at a standstill.
■ Check of all refrigerant pipes
and insulation for damage.
■ Check of all electrical
connections between indoor
unit and outdoor unit for
correct polarity.
■ Check that all fastenings,
mountings etc. are firm and at
the correct level.
Commissioning
Commissioning should only be
performed and documented by
specially trained personnel.
Observe the manuals for the
indoor unit and outdoor unit
when commissioning the
entire system.
NOTE
The system can be commissioned
once all the components have
been connected and checked.
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.
Add refrigerant
The unit contains a basic quantity
of refrigerant.
In addition, an additional amount
of refrigerant must be added for
refrigerant pipe lengths exceeding
5 meters per circuit. Refer to the
following chart:
Note that the employed
refrigerant is always filled in
liquid form!
CAUTION
NOTE
Check the overheating to
determine the refrigerant fill
quantity.
Wear protective clothing when
handling refrigerant.
