4. Placement into service /
operation
The heat pump may only be started with a full water tank!
The unit must always be disconnected from the power
supply when the front cover is opened!
When the unit is disconnected, wait for the fan to stop
completely before the cover is opened!
Before starting the unit makes sure all connectors are
in place, and make sure the cable between display and
controller is mounted correctly!
4.1 Demands to the hot water circuit
In the hot water system the following materials may be used:
- Copper
- Stainless steel
- Brass
- Plastics
Depending on the used materials in the water circuit (in
the house) wrong combinations of materials may lead to
corrosion damages. Special attention is required when using
galvanized steel or aluminium materials.
4.2 Starting to use of the water circuit
- Fill the tank using the valve on the supply line, and let the
air out through one of the upper hot tap water valves until air
no longer is present in the tapped water.
- Check the entire water circuit for tightness.
- Connect the heat pump to the power supply.
After starting to use the system the entire water
circuit must be checked for tightness.
4.3 Placement into service of the water circuit
Fill the container via the connecting branch, and aerate
the tank by letting one of the hot water taps located at the
highest elevation within the dwelling stand open until air no
longer comes out with the water.
The container can normally hold 290 litres of water.
Check the entire circuit to be sure it is sealed.
4.4 Electricity – connecting
Connect the Vanvex Lite to the public electrical grid.
4.5 The cooling circuit
The cooling circuit is delivered ready to run and no
work need be performed on it. The electronic controls
automatically take over all functions concerning the
operation of the compressor as well as the ventilator.
If needed, set the controls to the desired water temperature.
The factory setting is 50° C (see the operating instructions
for more detailed directions).
Installation Manual
4.6 Hints for energy savings
Do not set the water temperature higher than necessary.
The best utilisation of the Vanvex Lite occurs at low water
temperatures.
The use of circulation will increase the energy consumption
of the heat pump significantly.
4.7 Hints for fan operation
When using ductwork it may be necessary to run the fan on
a higher speed to compensate for the pressure losses.
4.8 Checking
After completing installation it is advised to check all
connections etc. to ensure they are tight and to check that
condensate water can flow to the drain unrestricted.
For servicing please refer to user manual.
5. Service / Maintenance
For maintenance, refer to the operating instructions.
