Important Information
1.
In the case of using water or simply an additive mixture, it is necessary to
ensure the continuous operation of the circulator that causes the water to flow
through the LWRc-8kW. It is recommended to use a 5% industrial ethanol as an
additive mixture based on its extending of the freeze function and the radical
reduction in the tear strength of the ice.
2.
When operating at low temperatures, the unit automatically provides defrosting,
which is accompanied by the drainage of the defrosted air-humidity condensate
in a volume of 0–1 litres per hour.
3.
The device comes equipped with a heating cable that is in operation during
defrosting. It is functional to lead the heating cable loop into a sewer or a
drainage outlet, for example.
4.
In the event of the accidental occurrence of poor drainage of the condensate and
the subsequent freezing of the heat pump, it is necessary to defrost the device by
means of a brief external intervention, e.g. using a tent and a heat gun.
It is necessary to protect the heat pump at the inlet of heating water by a
regularly cleaned filter
5.
It is possible to purchase an installation kit (USP) for the heat pump that
implements both a protective and an operational function. When installing it
into an existing heating system with the possibility of the temperature reaching
more than 60 °C, its use represents a condition for granting a warranty for the
heat pump.
