Page 4
•
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 24VDC; 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.
