Commissioning

 DANGER!

 

The unit may be commissioned only with 
the air ducts and weather grille or rain 
guard installed and with the covers closed.

Proceed as follows:

  Conduct a thorough installation inspection and go 

through the items on the general checklist.

 

The installation inspection will prevent damage 
to the heat pump system that could be caused by 
incorrect installation work.

 

Make sure of the following…

 

Clockwise rotary field

 of the load power 

supply (compressor).

 

Installation and assembly

 of the heat pump 

according to the information in this operating 
manual.

 All electric installation work must be properly 

completed.

 A 

3-pole automatic circuit-breaker

 must be 

installed for the compressor. It must have a con-
tact gap of at least 3 mm.

 The heating circuit must be flushed, filled and 

thoroughly bled.

 All valves and shut-off devices of the heating cir-

cuit must be open.

 All pipe systems and components of the system 

must be sealed.

  Carefully fill out and sign the completion report for 

heat pump systems…

  In Germany and Austria:

 

Send completion report for heat pump systems and 
general checklist to the manufacturer’s factory cus-
tomer service department.

 

In other countries:

 

Send completion report for heat pump systems 
and general checklist to the manufacturer’s local 
partner.
