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 R’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 R is running, some condensation water
will occur, which is conducted to the drain connecting branch
(1).
The quantity of condensation water
depends upon the humidity of the air
going through the inlet to the Vanvex R.
The condensation connecting branch
must be equipped with a hose with a
tight air trap, and run to a drain. The air
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 air trap is omitted, water
damage or damage to the Vanvex Lite can arise!
If the air trap is not correctly mounted, the
warranty will not apply!
3.4 Air intake and exhaust
Make sure that there is sufficient free-space around the
Vanvex R.
Inlet air
The inlet air may not be polluted with aggressive
components! (Ammonia, sulphur, chlorine etc.)
Parts in the system may be damaged.
Air connectors
Inlet and outlet ducts must be made of smooth pipes
to minimize pressure losses. Consider the fan working
pressure and the duct resistance during installation. (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, easy to cut of.
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
and when the heating pump is standing still.
The heating pump may only be used with the
tank filled up!
The unit must always be disconnected from the
power before the front door is removed. When
the unit is disconnected from the power please
wait until the fan has stopped before opening the
front doors!
Before starting up the unit please ensure that all
cables and electric plugs are connected correctly
and the cable and plug between the display in the
door and the circuit board are connected!
It is advised to insulate all ducts to lower heat loss and to
lower the noise level.
3.5 Checking
After the installation, it is recommended that the checks be
performed to ensure that the connections are sealed and
that the drainage of the condensation water is unobstructed.
