ATTENTION!
The dirt trap must be inserted in the heat source inlet of the heat pump to protect the
evaporator against the ingress of impurities.
Clean the dirt trap’s fi lter screen one day after start-up and subsequently in weekly intervals. If no more signs of
contamination are evident, the fi lter can be removed to reduce pressure drops.
Sometimes when the heat pump has started you can see the fl uid in the refrigerant circuit bubble for a few minutes
in the sight glass. This is completely normal. However, if it bubbles continuously you should contact your dealer.
If the sight glass shows green this means there is no moisture in the system. If it is yellow there is moisture in the
system. If this happens, contact your dealer.
Residue from lubricants and sealants may also contaminate the heating water.
In the case of severe contamination leading to a reduction in the performance of the liquifi er in the heat pump, the
system must be cleaned by a heating technician.
According to today’s state of knowledge, we recommend using a 5 % phosphoric acid solution for cleaning purpos-
es. However, if cleaning needs to be performed more frequently, a 5 % formic acid solution should be used.
In either case, the cleaning fl uid should be at room temperature. We recommend fl ushing the heat exchanger in
the direction opposite to the normal fl ow direction. To prevent acidic cleaning agents from entering the heating system
circuit, we recommend connecting the fl ushing device directly to the fl ow and return fl ow of the liquifi er. It is important
that the system be thoroughly fl ushed using appropriate neutralising agents to prevent any damage from being caused
by cleaning agent residue remaining in the system.
Acids must be used with great care and all relevant regulations of the employers’ liability insurance associations
must be adhered to.
If in doubt, contact the manufacturer of the chemicals!
This heat pump is a quality product and is designed for trouble- free operation. In the event that a fault should occur,
it will be indicated on the heat pump manager display. Simply consult the Faults and Trouble-Shooting page in the op-
erating instructions of the heat pump controller. If you cannot correct the fault yourself, please contact your after-sales
service technician.
ATTENTION!
Any work on the heat pump may only be performed by authorised and qualifi ed after-sales service techni-
cians.
ATTENTION!
Disconnect all electrical circuits from the power source prior to opening the device.
