12  Maintenance

  NOTE

We  recommend  that  you  conclude  a 
maintenance  agreement  with  an  accredited 
heating company.

12.1 Basic principles

The  refrigerant  circuit  of  the  heat  pump  requires  no 
regular maintenance.

Local regulations– e.g. EU Regulation (EC) 517/2014 – 
include a requirement for leakage controls beforehand 
and/or for a log book to be kept for certain heat pumps.

 

Ź

Ensure  compliance  with  local  regulations  with 

UHJDUGWRWKHVSHFL¿FKHDWSXPSV\VWHP

12.2 Maintenance as required

Yearly, more frequently if necessary: 

 

Ɣ

Checking  and  cleaning  the  components  of  the 
heating  circuit,  e.g.  valves,  expansion  vessels, 

UHFLUFXODWLQJSXPSV¿OWHUVGLUWWUDSV

 

Ɣ

Test the function of the safety valve for the heating 
circuit.

 

Ɣ

Check  regularly  to  ensure  that  the  condensate 
can drain out of the unit freely, without obstruction. 
To this end, check the condensate pan in the unit 
and  the  evaporator  regularly  for  dirt  /  blockages 
and clean as necessary.

 

Ɣ

Check at regular intervals whether the evaporator 
and the leaf guard need to be cleaned.
