Start up

After all components are 
connected and tested, the system 
can be put into operation. To 
ensure proper function, a function 
test should be made to recognize 
any irregularities during operation 
of the units before transfer to the 
client.

 
Function test and test run 

Check the following points.

■ 

Leak tightness of refrigerant 
lines.

■ 

Even run of compressor and 
fan.

■ 

Discharge of cold air on the 
interior unit and heated air on 
the exterior unit during cooling 
operation. 

■ 

Function test of the interior unit 
and all program runs.

■ 

Check of the surface 
temperature of the suction 
line and determination of 
evaporator overheating. To 
measure the temperature, hold  
the thermometer to the suction 
line and subtract the boiling 
point temperature reading on 
the pressure gauge from the 
measured temperature.

■ 

Documentation of the 
measured temperatures in the 
start up protocol.

Function test of Cooling 

operating mode

1.  Remove the caps on the valves.

2.  Start operation by opening 

the blocking valves of the 
exterior unit momentarily until 
the pressure gauge shows a 
pressure of approx. 2 bar. .

3.  Check all connections for leaks 

with leak detection spray and 
suitable leak detectors.

4.  If not leaks are found, open the 

blocking valves by turning them 
in counterclockwise direction 
with a hexagon wrench to the 
stop. If leaks were found, draw 
off the refrigerant and rework 
the defective connection. In 
this case, a new vacuum and 
drying procedure is imperatively 
required!

5.  Turn the main switch on the 

building or the fuse on.

6.  Turn the unit on via the remote 

control and select the cooling 
mode, maximum fan speed and 
lowest nominal temperature.

7.  Measure all required values, 

record them in the start up 
protocol and check the safety 
functions.

8.  Check the unit control with 

the functions described in 
chapter  „Operation“. 
Timer, temperature setting, fan 
speed and change between air 
circulation or dehumidification 
mode.

9.  Check the function of the 

condensation line by pouring 
distilled water into the 
condensation pan.    
To do so, use a spout to guide 
the water into the condensation 
pan.

10. Switch the interior unit to 

cooling mode.

11. Check all regulating, control 

and safety devices for function 
and correct adjustment during 
the test run.

12. Check the control of the 

interior unit with the functions 
described in the operating 
instructions   
(Timer, temperature 
adjustments and all mode 
settings).

13. Measure the overheating, 

external, internal, discharge and 
evaporator temperatures and 
record the test data in the start 
up protocol.

14. Remove the pressure gauge 

and install the caps.

The start up may only be 
made by especially trained 
technicians and must be 
documented accordingly.

      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 

■ 

Reinstall all parts which were 
removed.

■ 

Familiarize the operator with 
the system.
