9.4 Maintenance
Devices with a minimum of 3 kg refrigerant, or hermetically
sealed devices with a minimum of 6 kg refrigerant must be leak-
proof tested yearly by the operator according to (EC)
No. 842/2006.
The leak-proof testing is to be documented and archived for a
minimum of 5 years. The test is to be carried out by certified per-
sonnel only according to (EC) No. 1516/2007. The attached table
can be used as a basis for the documentation.
ATTENTION!
The supplied strainer must be fitted in the heat source inlet of the heat
pump in order to protect the evaporator against the ingress of impurities.
The filter screen of the strainer should be cleaned one day after
commissioning, thereafter every week. If no more contamination
can be noticed any more, the strainer filter can be removed in
order to reduce pressure losses.
