OPERATING CONDITIONS & REQUIREMENTS
OPERATING PRESSURE MIN-MAX: 1,4-8,3 bar / 20-120 psi
•
 this appliance is configured to perform optimally at an
operating pressure of 3 bar (45 psi) ±½ bar (7 psi); in case of a
lower or higher operating pressure the performance may be
affected negatively!
 check water pressure regularly; it may fluctuate severely
depending on the time of day, the day of the week or even the
season of the year.
 take into account that night time water pressure may be
considerably higher than day time water pressure.
 install a pressure reducer ahead of the appliance if necessary.
 install a pressure booster, if it is likely that water pressure may
drop below the minimum.
OPERATING TEMPERATURE MIN-MAX: 2-48 °C / 35-120 °F
•
 do not install the appliance in an environment where high
ambient temperatures (e.g. unvented boiler house) or freezing
temperatures can occur.

direct sunlight or atmospheric precipitation.
 do not install the appliance too close to a water heater; keep at
least 3 m (10 ft) of piping between the outlet of the appliance
and the inlet of the water heater; water heaters can sometimes
transmit heat back down the cold pipe into the appliance;
always install a check valve at the outlet of the appliance.
ELECTRICAL CONNECTION:
•
 the appliance only works on 24 VDC; always use it in
combination with the supplied transformer.
