Set-up and installation

WARNING!

Cooling systems (heating pumps), climate control systems and heating devices that have been set 
up and installed incorrectly can both endanger life and health of people and be impaired in their func-
tion.

Work on the ROTEX HPSU monobloc compact (such as e.g. installation, repair, connection and ini-
tial commissioning) must only be carried out by persons who are authorised, who have successfully 
completed 

qualifying technical or vocational training 

for the respective activity and who have 

taken part in advanced training sessions recognised by the relevant responsible authority. This 
especially includes 

heating specialists and specialist electricians

, who have experience in the 

proper installation and maintenance of heating systems due to their 

technical training

 and 

special-

ist knowledge

.
