Commissioning
NOTE
Commissioning should only be
performed and documented
by specially trained personnel.
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.
Functional checks and
test run
Check the following points.
■ Tightness of the refrigerant
pipes.
■ Compressor and fan running
smoothly.
■ In cooling mode, cold air should
be output by the indoor unit,
and warm air should be output
by the outdoor component.
■ Functional test of the indoor
unit and all program sequences.
■ Check the surface temperature
of the suction pipe and
determine the overheating
of the vaporiser. Measure
the temperature by holding
a thermometer against the
suction pipe and subtracting
the boiling point temperature
indicated on the pressure
gauge.
■ Record the measured
temperatures in the
commissioning report.
Functional test for cooling mode
1. Remove the protective caps on
the valves.
2. Start the commissioning
procedure by briefly opening
the stop 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.
4. If no leaks are found, fully
open the stop valves by turning
them anti-clockwise using a
spanner. If leaks are found,
repair 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
(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
chapter "Operation". Timer,
temperature setting, fan speeds
and switching to ventilation or
dehumidifying mode.
Prior to commissioning,
check the correct assignment
of the electrical cables and
refrigerant pipes!
Do not mix up the connections
between circuits.The incorrect
assignment of control cables
and refrigerant pipes can
have fatal consequences
(compressor damage)!
Each circuit must be separately
commissioned in the following
order.
