Checking The Filling Level And Filling Pressure Of The Brine Circuit (Vws Only) - Vaillant geoTHERM VWS 220/2 Instrucciones De Operación

6.3.2 Checking the filling level and filling
pressure of the brine circuit (VWS only)
Caution!
b
Risk of damage from escaping brine!
If there are leaks in the brine circuit, brine
can escape, which can result in damage.
> In the event of leaks in the brine circuit,
switch off the heat pump. To do this,
switch off the circuit breakers for the
heat pump.
> Any leaks should be repaired by your
heating engineer.
Caution!
b
Risk of damage due to loss of brine!
If the filling level of brine fluid is too low,
this can damage the heat pump.
> Check the filling level of the brine fluid
after commissioning every day for a
week and then twice a year.
> Have your heating engineer refill the
brine fluid.
6.1 Filling level of the brine expansion tank
It is normal for the filling level of the brine to fall a little in
the first month after the start-up of the system. The filling
level can also vary depending on the temperature of the
heat source. It must never fall to the extent that it is no
longer visible in the brine expansion tank, however, other-
wise air may enter the brine circuit.

Care and maintenance
> Check the brine level or filling pressure in the brine cir-
cuit at regular intervals. You can read the filling pressure
of the brine circuit („Brine pressure") from the heat
pump controller (¬ section 4.8, menu
The filling pressure should be between 1 and 2 bar. If the fill-
ing pressure falls below 0.2 bar, the heat pump will be shut
down automatically and a fault message will be displayed.
