incoming water's direction fig.(5 и 6) Additional stopcocks must not be mounted
between the safety return-valve and the water heater.
Exception: If the local regulations (norms) require the usage of another protection
valve or mechanism (in accordance with EN 1487 or EN 1489), it must be bought
additionally. For mechanisms operating in accordance with EN 1487 the announced
operational pressure must be no more than 0.7 MPa. For other protection valves,
the pressure at which they are calibrated must be 0.1 MPa lower than the one
marked on the appliance's sign.
•
During use (water heating mode), the dripping of water from the safety return-
valve's drainage opening is normal. The same must be left open to the atmosphere.
•
The safety valve and the pipe between the valve and the water heater must be
protected from freezing. During hose draining - its free end must be always open
to the atmosphere (not to be immersed). Make sure that the hose is also protected
from freezing.
•
In order to secure the water heater's safe operation, the safety return-valve
must undergo regular cleaning and inspections for normal functioning /the valve
must not be obstructed/, and for the regions with highly calcareous water it must
be cleaned from the accumulated lime scale. This service is not provided under
warranty maintenance.
•
If the probability exists for the premise's temperature to fall below 0°C, the
storage tank must be drained via raising the safety return-valve's lever. If upon
turning the valve's knob when the water tank is full, water do not start running from
the valve's drainage opening, this is a signal of malfunction and the appliance's use
must be discontinued.
