► Ensure compliance with local regulations with
regardtothespecicheatpumpsystem.
11.2 Maintenance as required
● Yearly, more frequently if necessary:
–
Checkingandcleaningthecomponentsofthe
heating circuit and the heat source, e.g. valves,
expansion vessels, circulation pumps, lters,
dirt traps.
–
Checking the function of the safety valve (on
site) for the domestic hot water tank and the
safety valve for the heating circuit.
11.3 Yearly maintenance
► Record the quality of the heating water analytically.
Incaseofdeviationsfromthespecications,take
suitable measures without delay.
Clean unit variant with SVGW storage tank (SVGW:
Swiss gas and water association (Schweizerischer
Verein des Gas- und Wasserverbands)):
1. Drain the domestic hot water tank via the drain
valve at the domestic cold water inlet.
2. Ventthedomestichotwatertankandpipesviathe
