Function test of the cooling
and heating modes
1. Remove the protective caps
from the valves.
2. Start the commissioning
procedure by briefly opening
the shut-off valves on the
outdoor component until
the pressure gauge indicates
a pressure of approx. 2 bar.
3. Use leak detection spray or
suitable devices to check that all
the connections are tight.
Final tasks
■
Reassemble all disassembled
parts.
■
Familiarise the operator with
the system.
4. If no leaks are found, fully open
the shut-off valves by turning
them anti-clockwise using a
spanner. If leaks are found,
remedy the faulty connection.
It is imperative that the vacuum
creation and drying steps are
repeated!
5. Switch off the main circuit
breaker or remove the fuse (to
be provided by the customer).
6. Use the remote control to
switch on the unit and select
the cooling mode, maximum
fan speed and lowest target
temperature.
7. Measure and record all
the required values in the
commissioning report and
check the safety functions.
8. Check the indoor unit control
system using the functions
described in the "Operation"
section. Timer, temperature
setting, fan speeds and
switching to ventilation or
dehumidification mode.
9. Check the correct function
of the condensate line by
pouring distilled water into the
condensation tray.
A bottle with a spout is
recommended for pouring the
water into the condensation
tray.
10. Switch the indoor unit to
cooling mode.
11. Check the correct function
and settings of all regulation,
control and safety devices
during the test run.
12. Check the control system in the
indoor unit using the functions
described in the Operating
Manual.
Timer, temperature settings and
all mode settings.
13. Check the overheating,
outdoor, indoor, outlet and
vaporisation temperatures and
record the measures values in
the commissioning report.
14. Switch the indoor unit to
heating mode.
15. Check the functionality of all of
the previously described safety
devices and during the test run.
16. Record the measured values in
the commissioning report.
17. Remove the pressure gauge.
Check that seals have been
fitted in the sealing caps.
Check that the shut-off
valves and valve caps are
tight after carrying out any
work on the cooling circuit.
Use appropriate sealant
products as necessary.
