Maintenance, cleaning and care instructions
10.1
Maintenance
According to the EC-VO 842/2006 (F gas regulation) it is necessary to submit all coolant circuits of a coolant quantity
>3kg (6 kg for hermetic systems) to a leak test every year. The coolant can be taken out of the machine via the type
plate. The leak test must be performed by certified staff according to (EC) No 1516/2007. Document the leak test and
keep the log of the machine and the log of the leak test for at least five years.
Perform the maintenance of the refrigerant components according to VDMA 24186-3
10.2
Cleaning of the heating system
Oxygen can form oxidation products (rust) in the heating water circuit in particular when using steel components. They
attain the heating system via valves, re-circulation pumps or plastic tubes. Therefore, it is particularly necessary to make
sure that the installation is diffusion tight in particular for tubes of the floor heating system.
Also remainders of lubricants and sealants may contaminate the heating water. If the water is heavily soiled so that the
performance of the condenser in the heating pump is reduced, it is necessary to have the system cleaned by an install-
er. At this the condenser should be flushed contrary to the direction of flow.
In order to avoid that soiled heating water attains the heating system circuit we recommend you to directly connect the
flushing device to the flow and return of the condenser of the heat pump. In order to avoid failures due to dirt deposits
it is necessary to make sure that the heat exchanger in the heating system cannot be soiled by installing a dirt trap.
10.3
Care
The external parts of the heat pump can be treated with a damped cloth and commercially available cleaning agents.
Generally avoid depositing or cleaning any objects on the heat pump in order to protect the lacquer.
Do not use any cleaning agents containing soda, acids, sand or chlorine in order to
protect the surface.

Failure
The heat pump bravour is a quality product and should work trouble-free. Before delivery our products are tested in
order to make sure that they are delivered without damages and functional. However if a failure occurs it is displayed
on the heat pump controller.
Any possible errors and their corresponding remedies are listed in the instructions of the controller (refer to part 2 of
the operating instructions). If it is not possible to remove a failure by oneself inform an approved installer or service
technician.
