3. INSTALLATION
3.1 Water connection
During installation, regard must be paid to the dimensions of
the pipes with respect to the pre-existing water pressure and
the pressure loss in order to ensure sufficient pressure and
water flow rates at the draw-off point.
The maximum working pressure is 10 bars, and the maximum
operating temperature is 65°C. If necessary, the supply
pipe must be equipped with a pressure reduction valve and
possibly a filter.
As for all pressure vessels, the Vanvex RS’s connections
must also be equipped with an approved safety valve on
the service side and an approved check valve on the supply
side.
All pipe work must comply with water safety regulations.
3.2 Placement of pipe
connections
Hot water outlet is mounted on the upper
connecting branch. (¾” RG)
If the unit is used with the circulation
of the hot water supply, the middle
connecting branch is used as a return
path. (¾” RG)
Inlet of fresh cold water is mounted on
the bottom connecting branch. (¾” RG)
It is recommended to use 3/4“
flextube for the connection of the
Waterconnection, to avoid possible
sound from the vibration.
No holes for fittings or the like may be drilled in
the product!
Such would be able to damage the functionality
of the product and cause the product to have to
be scrapped!
3.3 Connection of condensation drain
While the Vanvex RS is running, some
condensation water will occur, which
is conducted to the drain connecting
branch 3/4” (1).
The quantity of condensation water
depends upon the humidity of the air
going through the inlet to the Vanvex RS.
The condensation connecting branch
must be equipped with a hose with a air
tight water trap, and run to a drain. The
water trap must contain a water column
of at least 60 mm.
It is also possible to use other tight
air traps, like a tube with one turn.
If mounting of the water trap is omitted, water
damage or damage to the Vanvex RS can arise!
If the water trap is not correctly mounted, the
warranty will not apply!
3.4 Air intake and exhaust
Make sure that there is sufficient space around the Vanvex
RS.
Inlet air
The inlet air may not be polluted with aggressive
components! (Ammonia, sulphur, chlorine etc.)
Parts in the system may be damaged.
Air connections
Inlet and outlet ducts must be made of smooth pipes
to minimize pressure losses. Consider the fan working
pressure and the duct resistanc (See technical data).
It is advised to install the air ducts that are placed near the
heating pump, levelled or with a light fall towards the extract
air outlet to avoid leaking of condensed water. This will
avoid leaking of condensed water from the ducts.
When air ducts are placed outside the building the back
pressure valve (with a small resistance) should be placed to
ensure no cold air is entering the room in the winter time if
the heating pump is standing still.
The heat pump may only be used with the boiler
filled up!
The unit must always be disconnected from the
power before the front panel is removed. When
the unit is disconnected from the power, please
wait until the fan has stopped before opening the
front panel!
It is advised to insulate all ducts to lower heat loss and to
lower the noise level.
3.5 Connection of heat exchanger
In the heat boiler the can be a heat exchanger of 0,95 m²
installed, which is enamelled outside. The connection is
in ¾” RG. In the sensor pipe for the thermostat sensor
there can also be placed a sensor to control the external
connection fx wood burner etc. The sensor can max. have a
diameter on 6 mm.
