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.
the appliance cannot be exposed to outdoor elements, such as
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.
make sure to plug the transformer into a power outlet, which is
installed in a dry location, with the proper rating and over-
current protection.
