Please note the following during installation:
- File Operating instructions so that they are readily available
- Install Heating unit in a frost- and draught-free room
- Automatic vent valve has to be installed at the highest point in an frost-free 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 vertically
- Max. length of insulated circuit (return flow inclusive) should not exceed 200 m (656 feet)
- Electrical installation must be completed by an authorized electrician
- 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.
- Never use heating unit without water
- Circulation Pump must work on controller switch position 3
- Circuit pipes must be insulated, minimum thickness 30 mm, heat conductivity
- Do not use cold water - plastic pipes.
- Adjusted temperature refers to return flow temperature
- 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 into the bowls and directly into the water circuit.
These air bubbles can lead to the setting of the STB alarm in the heating unit.
In case of a domestic (own) water supply, a water store tank / pressure accumulator
has to be installed.
