❹ Maintenance
4.1 I Winterizing
•
Stop the water circulation.
•
Clean the filter (see
§4.1.2 Backflushing
).
•
Drain the water out of the filter (see
§4.1.3 Replacing the filter media
), and the entire hydraulic circuit.
•
If the filter is positioned below the water level, close the isolation valves at suction and discharge.
•
Turn the lever of the multiway valve to an intermediate position (between any 2 settings) to preserve the internal
gasket.
4.2 I Maintenance
4.1.1 User maintenance
•
Clean the outside of the appliance, do not use solvent-based products.
•
Check the filter pressure and the condition of the pressure gauge and the air release once a week.
•
Remove debris from the pump's pre-filter basket (see pump manual).
•
Check that there are no leaks in the hydraulic circuit.
4.1.2 Backflushing
•
Stop the filter pump and make sure to switch off your water treatment appliance if any, since water will not flow in
this part of the hydraulic circuit.
•
Check that the pressure shown on the pressure gauge is 0 bar.
•
Set the valve to position "backwash" and switch on the filter pump again.
•
When the water appears clear through the transparent window on the side of the multiway valve, switch off the filter
pump.
•
Set the valve to the "rinse" position and switch the filtration system back on.
•
When the water appears clear through the transparent window on the side of the multiway valve, switch off the filter
pump.
•
Set the valve to the "filter" position and switch the filter pump back on.
Tip: backflushing
•
Quickly switch back and forth between the "backwash" and "rinse" positions in order to unclog and more
easily clean the filter medium. This process reduces water consumption.
•
Backflush when water circulation becomes more difficult (pressure more than 0.3 to 0.5 bar above normal
pressure, in the yellow or red area of the pressure gauge).
•
Backflushing is recommended once a month.
4.1.3 Replacing the filter media
•
Stop the water circulation.
•
Set the valve to position "closed" and close the other valves as a precaution.
•
Open the air bleed screw on the cover and unscrew the drain plug to drain the water from the filter.
•
Take off the cover then remove the filter media manually or using a water and dust vacuum cleaner (take care not to
damage the diffuser, the manifold and its strainers).
•
Fill the filter with new filter media (see
§2.2.3 Filling the filter
).
