Operating Conditions & Requirements - ProFlow PF-PHN Mode D'emploi

OPERATING CONDITIONS & REQUIREMENTS
APPLICATION LIMITATIONS:
•
 incoming pH: pHneutralizer: 6,0 - 7,0
If the pH of the incoming water is below the stated levels, insufficient
correction of the pH may occur, i.e. the pH at the outlet of the appliance may
not be raised as expected.
 incoming hardness: max. 100 mg/L as CaCO
hardness levels the appliance will still function, but the filter media will
become 'caked', reducing its lifespan; increasing the regeneration frequency
(i.e. reducing the number of days between 2 regenerations) may prevent this
from happening.
 outgoing hardness: as a result of the dissolution of the filter media, the water
hardness at the outlet of the aplliance will increase; a water softener may
become necessary.
OPERATING PRESSURE MIN-MAX: 2,0-8,0 bar / 29-116 psi
•
 low operating pressure may lead to insufficient backwash of the filter media,
resulting in an increase in pressure drop and/or a reduction of the filtration
capacity during the service cycle.
 if installed on a well, verify that the well pump is powerful enough to provide
sufficient flow rate for the backwash cycle.
 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: 4-38 °C / 39-100 °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:
•
 this appliance only works on 24 VDC; always use it in combination with the
supplied transformer.
 in case of damage to the power supply cable of the transformer, immediately
disconnect the transformer from the power outlet and replace the
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.
