Commissioning
Once all the components have
been connected and tested, the
system can be commissioned
. 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.
Function test and
test run
Check the following points:
■ Leak tightness of refrigerant
lines.
■ Compressor and fan running
smoothly.
■ In cooling mode, cold air
output by the indoor unit, and
warm air output by the outdoor
component.
■ Functional test of the indoor
unit and all program sequences.
■ Check of the surface
temperature of the suction
pipe and determination of
vaporiser overheating. 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 temperature.
■ Documentation of the
measured temperatures in the
commissioning report.
Function test of Cooling
operating mode
1. Remove the caps
from the valves.
2. Begin the commissioning
process by briefly opening the
shut-off valves of the external
unit until the manometer
displays a pressure of approx.
2 bar.
3. Use leak detection spray or
suitable devices to check that all
the connections are tight.
4. If no leaks are found, open
the stop valves by turning them
anti-clockwise as far as they will
turn using a hexagon spanner.
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!
5. Switch on the mains switch
or circuit breaker.
6. Use the remote control to
switch on the unit and select
the cooling mode, maximum
fan speed and lowest nominal
temperature.
7. Measure and record all
the required values in the
commissioning report and
check the safety functions.
8. Check the control system
for the unit using the
functions described in the
chapter "Operation". Timer,
temperature setting, fan speeds
and switching to circulating or
dehumidifying mode.
9. Check the correct function
of the condensation 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 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 measured values
in the commissioning report.
14. Remove the pressure gauge
and fit the sealing caps.
Commissioning is only to be
performed and documented
by specially trained personnel.
NOTE
Due to the turn on delay, the
compressor will start up a few
minutes later.
NOTE
Then, check the blocking
valves for leaks.
NOTE
Final tasks
■ Reassemble all disassembled
parts.
■ Familiarise the operator with
the system.
