7.2 Heating system connection
The heating system connections on the hydro tower have a 1 1/
4" flat-sealing external thread. A spanner must be used to firmly
grip the transitions when making the connections.
A dimensionally stable ¾" plastic hose (inner diameter approx.
19 mm) must be affixed to the hose nozzle, e.g. with a pipe
clamp, and guided outside the building in the area behind the
heat pump return.
Before the heating water system is connected, it must be flushed
to remove any impurities, residue from sealants, etc. Any accu-
mulation of deposits in the liquefier may cause the heat pump to
completely break down. For systems in which the heating water
flow can be shut off via radiator or thermostat valves, the infinitely
adjustable circulating pump carries out a demand-related adjust-
ment of the delivery height. The initial filling and start-up must be
carried out by an authorised specialist company. The entire sys-
tem, including all factory-assembled components, should be in-
spected to ensure that everything is working properly and that
there is no leakage.
The buffer tank and heating system must be filled via the filling
and drain cock on the hydro tower. The cylinder must be de-aer-
ated using the air-relief cock on the upper pipe connection to the
cylinder.
The isolation ball valve above the heat circulating pump (M13) is
equipped with a check valve with an "air lock". This makes it pos-
sible for air to escape from the HWK's pipe system via the check
valve and into the connected heating circuit when the ball valve
is open. A suitable means of de-aeration must also be installed in
the heating circuit on site.
It is additionally recommended that an isolation device be in-
stalled in the heating return before integration into the HWK is
carried out. This isolation device should prevent excessive heat-
ing water loss if it becomes necessary to replace the "auxiliary
circulating pump" (M16).
If it is necessary to connect heating connection pipes to the rear
of the cylinder, these can also be laid underneath the cylinder.
It is possible to connect a second or third heating circuit (acces-
sory component "Manifold bar VTB 25"). For this extension to be
made, the heat circulating pump (M13) in the HWK must be re-
moved and replaced with a suitable adaptor (inner micrometer
180 mm).
The heating circuits are then installed on site outside of the HWK.
NOTE
If the pipes are more than 10 m long, the free compression values stated
in the device information must be observed (minimum pipe diameter for
volume flows of more than 1.5 m³/h: DN 32)

Minimum heating water flow
The minimum heating water flow of the heat pump is ensured by
the the dual differential pressureless manifold in all operating
states of the heating system.
A method of manual drainage must be provided for heat pumps
which are exposed to frost. The frost protection function of the
Heat pump manager is active whenever the heat pump manager
and the heat circulating pump are ready for operation. The sys-
tem has to be drained if the heat pump is taken out of service or
if a power failure occurs. The hydraulic network should be oper-
ated with suitable frost protection if heat pump systems are im-
plemented in buildings where a power failure cannot be detected
(vacation homes etc.).
