9 Before commissioning
Perform the following checks prior to putting the
unit into operation for the first time and after any
work on the cooling cycle. Record the results in the
commissioning report:
n Check all refrigerant piping and valves for leak-
tightness using leak detection spray or soapy
water.
n Check the refrigerant piping and insulation for
damage.
n Check the electrical connection between the
indoor unit and the outdoor unit for correct
polarity.
n Check that all fastenings, mountings, etc. are
firm and at the correct level.
10 Commissioning
NOTICE!
Commissioning should only be performed by
specially trained personnel and documented
after the certificate has been issued. Observe
the operating manuals for the indoor unit and
outdoor unit when commissioning the entire
system.
Once all the components have been connected
and tested, the system can be put into operation. A
functional check should be performed to verify its
correct function and identify any unusual operating
behaviour prior to handing it over to the operator.
NOTICE!
Check that the shut-off valves and valve caps
are tight after carrying out any work on the
cooling cycle. Use appropriate sealant prod-
ucts as necessary.
Functional checks and test run
Check the following points:
n Leak-tightness of the refrigerant piping.
n Compressor and fan running smoothly.
n In cooling mode, cold air output by the indoor
unit, and warm air output by the outdoor unit.
n Function test of the indoor unit and all program
sequences.
n Check of the surface temperature of the suc-
tion pipe and that the vaporiser is not over-
heating. To measure the temperature, hold the
thermometer to the suction pipe and subtract
the boiling point temperature reading on the
pressure gauge from the measured tempera-
ture.
n Record the measured temperatures in the
commissioning report.
