Technical Data - Suevia 303 Notice D'utilisation

Heating Unit Mod. 303 / Mod. 300 must be fix installed and permanently wired.
Use distribution box of min IP 54.
Local national rules and regulations must be adhered to!
230 V / 400 V AC; 50 Hz; 1~; max. 3,0 kW; According connection diagram, observe VDE 0100!
All installation, maintenance and inspection works of the unit must be carried out only by an
authorised and qualified specialist.
Heating Unit must be used in conjunction with a own residual
current device 230 V - 0,03 A / 400 V - 0,03 A !
A damaged heating or pump can cause that the residual current circuit breaker triggers and the
heating unit and pump is out of function. This leads to the possibility that the water supply line
risks to freeze due to certain cold outside temperature.
Special and corresponding steps have to be taken at the spot by the user to protect it
against freezing: e.g. frost protection heating cables, warning system, etc.

Question:
Calculation:
Answer:
Water flow quantity depends on the following conditions:
Water pressure, length of pipes and cross sectional area as well as the quantity of reduction
pieces and curves.
Experimental values, based on field test, revealed that not all the drinking bowls are actuated at
the same time.
This way the result /field test has to be multiplied with factor two.

How many cattle bowls can be connected in addition?
150 l/min : 12 l/min = 12 pieces
12 pieces x 2 ( empirieal values) = 24 pieces
24 pieces of cattle drinking bowls can be connected.
