Commissioning
NOTICE!
Commissioning should only be performed and
documented by specially trained personnel.
Observe the operating manual for the indoor
units and outdoor components when commis-
sioning 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.
Function test of heating operating mode
1. Remove the protective caps from the valves.
2. Start the commissioning procedure by briefly
opening the shut-off valves on the indoor unit
until the pressure gauge indicates a pressure
of approx. 2 bar.
3. Check all connections for leaks with leak
detection spray and suitable leak detectors. If
no leaks are found, fully open the shut-off
valves by turning them anti-clockwise with
the cap of the valve. If leaks are found, draw
off the refrigerant and rework the defective
connection. It is imperative that the vacuum
creation and drying steps are repeated!
4. Activate the main circuit breaker or fuse (to
be provided by the customer).
5. Program the Smart-Control (see the relevant
instructions).
6. Switching on heating mode.
Due to the turn on delay, the compressor
will start up a few minutes later.
7. Check all regulating, control and safety
devices for function and correct adjustment
during the test run.
8. Measure all cooling data and record the
measured values in the commissioning
report.
9. Remove the pressure gauge.
Functional checks and test run
Check the following points:
n Leak-tightness of the refrigerant piping.
n Compressor and fan running smoothly.
n Issue of warmer water in the indoor module
and issue of cold air to outside module during
heating operation.
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.
Final tasks
n Use the Smart-Control to set the target temper-
ature to the required value.
n Re-install all disassembled parts.
n Familiarise the operator with the system.
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.
Adding refrigerant
DANGER!
The connection of refrigerant pipes and the
handling of refrigerant may be only be carried
out by qualified personnel (competence cate-
gory I).
DANGER!
Only refrigerant in a liquid state may be used to
fill the cooling cycle!
