REMKO SV 261 - Manual (Page 26)

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
component (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 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 correct polarity of the
connection between the indoor
unit and outdoor component.
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:

CAUTION
NOTE
Check the overheating to
determine the refrigerant fill
quantity.
Wear protective clothing when
handling refrigerant.
CAUTION
Commissioning should only be
performed and documented
by specially trained personnel.
NOTE
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.
■ Check that all fastenings,
mountings etc. are firm and at
the correct level.
