1.1 Important notes
ATTENTION!
Work on the heat pump must only be performed by
authorised and qualified after-sales service technicians!
ATTENTION!
When operating or maintaining a heat pump, the legal
requirements of the country where the heat pump is operated
apply. Depending on the refrigerant fill quantity, the heat
pump must be inspected for leaks at regular intervals by a
certified technician, and these inspections must be recorded.
ATTENTION!
The well water must comply with the required water quality
standards. (Cap. 9.4 on page 11)
ATTENTION!
If the heat pump or circulating pumps are controlled
externally, a flow rate switch is required to prevent the
compressor from being switched on when there is no volume
flow.
ATTENTION!
The heat pump must not be tilted more than 45° (in any
direction).
ATTENTION!
Before commissioning, the transport fastening must be
removed.
ATTENTION!
Flush the heating system prior to connecting the heat pump.
ATTENTION!
The maximum test pressure in the heating circuit and the
primary circuit is 6.0 bar. This value must not be exceeded.
ATTENTION!
With fully demineralized water, it is important to ensure that
the minimum permissible pH value of 7.5 (minimum
permissible value for copper) is complied with. Failure to
comply with this value can result in the heat pump being
destroyed.
ATTENTION!
It is essential that the dirt trap included in the accessories
pack is installed in the return (inlet).
ATTENTION!
The flow rate switch available as an accessory must be
installed in the flow (outlet) of the heat source.
ATTENTION!
Ensure that there is a clockwise rotating field: With incorrect
wiring the starting of the heat pump is prevented. A
corresponding warning is indicated on the display of the heat
pump manager (adjust wiring).
ATTENTION!
It is not permitted to connect more than one electronically
regulated circulating pump via a relay output.
EN-2
ATTENTION!
Start-up must be performed in accordance with the
installation and operating instructions of the heat pump
manager.
ATTENTION!
The supplied dirt trap must be inserted in the heat source inlet
of the heat pump to protect the evaporator against the ingress
of impurities.
ATTENTION!
Disconnect all electrical circuits from the power source prior
to opening the device.
