Technical Data; Electric Connection - SUEVIA 303 Montageanleitung

Heating Unit must be fix installed and permanently wired.
Use junction box of min IP 54.
Local norms and regulations must be respected! According connection diagram, observe VDE 0100!
All installation, maintenance and inspection works of the unit must be carried out by an authorised and qualified
electrician only.
Heating Unit must be used with one separate residual current device (RCD).
Mod. 303: 230 V - two-pole 30 mA, Mod. 300: 400 V - four-pole 30 mA.
A damaged heating or pump can cause that the residual current circuit breaker triggers and the heating unit and the
pump are out of function. This leads that the water supply line risks to freeze due to a 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.

* Theoretic values depend in practice on local circumstances and can result in lower values.
Example:
Local circumstances: 4 bar of pressure, ¾" water line (150 l/min)
Question: How many cattle drinking bowls can be connected?
Calculation: 150 l/min : 12 l/min = 12,5 pieces
12,5 pieces x 2 (experimental value*) = 25 pieces
Answer: 25 pieces of cattle drinking bowls can be connected.
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 value is based on field test, which revealed that not all the drinking bowls are actionned at the same
time. That's why the result has to be multiplied with factor two.
