10.2 Connecting the heat sink system
i Information
The hydraulic connection from the heat sink system
(WNA) to the heat pump may be made only by a
qualified contractor.
i
Information
For maintenance purposes, a shut-off valve should
be fitted to every hydraulic line close to the connec -
tion point on the heat pump.
i Information
We recommend installing an appropriately sized
heat pump buffer tank or a low loss header.
► The pipe network and the pumps should be correctly
dimensioned for your heating system and according
to the technical data for your heat pump.
► A (manual) air vent valve must be fitted at the highest
point in the pipework.
► At the lowest point in the pipework, fit a drain pipe to
allow the system to be drained.
► Ensure that no foreign bodies (dust, dirt etc.) can en-
ter the pipework.
► A guard (strainer) can be installed in the return line of
the heat pump to catch dirt.
i Information
Ensure that the guard is easy to clean for mainte-
nance purposes. A heavily soiled strainer can lead
to a high pressure safety shutdown or to a malfunc-
tion shutdown based on flow metering (heat sink).
i Information
Ensure that the flow velocity in the pipe network
does not exceed 0.8 m/s, as this can cause in-
creased noise emissions.
10.2.1 Connecting the heating water
»
Before connecting the heat pump, flush the pipework
through with filtered flushing water according to the
relevant standards. Foreign bodies such as rust,
sealing material and swarf will impair the operational
reliability of the heat pump.
