Please note the following during the installation:
- Archive this operating instructions so that they are available at any time.
- Install Heating unit in a dry, frost- and draught-free room.
- Automatic vent valve has to be installed at the highest point of the circuit in this room. If highest
point is not situated in a frost-free room, the valve has to be insulated or maintained frost-free
with a heating cable.
- Heating Unit has to be mounted horizontally.
- Never use heating unit without water. This can follow to the damage of the heating unit and of
the pump.
- Circulation Pump must work on controller switch position 3.
- Circuit pipes must be insulated, minimum thickness 30 mm, heat conductivity
- Do not use plastic pipes for cold water.
- Adjusted temperature refers to flow temperature.
- Electrical installation must be completely done by an authorized electrician.
- Max. length of insulated circuit (return flow inclusive) should not exceed 200 m (656 feet).
- All electric cables and pipes have to be installed that way that they are protected in a secure
way against possible mechanical damages or possible damages by animals.
- Attention has to be paid to the fact that in case of deaeration hot water can escape.
- During maintenance or repair of circuit the unit has to be separated from mains supply.
Important:
If water comes from a domestic water supply (own source, etc.), take care that water reserve
is enough, otherwise you risk a pressure drop. This happens, when e.g. a lot of water is taken
away at the same time.
This pressure drop leads to the creation of a vacuum in the water line.
To equalize this vacuum, air streams through the valves operated by the animals directly
into the water circuit.
These air bubbles can lead to the setting of the STB in the heating element.
In case of a domestic (own) water supply, a water store tank / pressure intensifier
has to be installed.
