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.
