22.1 Basic principles
The cooling circuit of the heat pump requires no
regular maintenance.
Local regulations – e.g. EU Regulation (EC) 517/2014 –
among other things, require leak checks beforehand
and/or for a logbook to be kept for certain heat pumps.
The hermetic tightness and refrigerant ll quantity are
criteria for whether a logbook has to be kept and leak
tests performed or not, and at what time intervals.
► Ensure compliance with local regulations with
regard to the specic heat pump system.
22.2 Maintenance as required
● Checking and cleaning the components of the
heating circuit and the heat source, e.g. valves,
expansion vessels, circulation pumps, lters, dirt
traps
● Test the function of the safety valve for the heat-
ing circuit
22.3 Clean and ush the evaporator
