3.3 I Operation
•
To prevent against any risk of explosion that may cause material damage, serious injury or
even death, make sure that the hydraulic circuit is free of any debris or blockage and is not
subject to excessive pressure, and that the filter cover is properly positioned and tightened.
•
Ensure that all valves are open and/or that the power of the filtration pump is suitable for the
size of the filter if the initial pressure is greater than 1.2 bar (17 psi).
•
Never change the position of the multiway valve when the filter pump is in operation.
•
Never dismantle the valve when the filter is pressurised.
•
Check:
- the correct tightening of the hydraulic connectors,
- the stability of the filter, which must be level,
- that the hydraulic circuit is drained and does not contain any debris,
- that the filter cover is closed properly,
- that the valves are open.
•
Open the filter isolation valves and the drain valve to the evacuation.
•
Open the filter cover air bleed screw.
•
Set the multiway valve to position "backwash".
• Start the pump.
•
When the filter level is at maximum (water comes out of the air bleed screw), close the cover air bleed screw.
•
Check that there are no leaks on the hydraulic circuit.
•
When starting for the first time, stay in position "backwash" until the water is clear in the transparent window on the
side of the multiway valve.
•
Stop the water circulation.
•
Set the valve to position "rinse" and switch on the water circulation until the water is clear.
•
Stop the filtration pump.
•
Set the multiway valve to position "filter" and start a normal filtration cycle.
•
Record the initial filter pressure shown on the pressure gauge to serve as reference value.
•
Make sure that the pressure indicated lies within the operating range (see
§"1.2 I Technical specifications"
).
Tip: installation with a variable speed pump
•
For an installation with a variable speed pump, it is normal to have a low initial pressure if the filtering
speed is low, and vice versa. In such a case, always use the same filtering speed as a comparison reference.
Tip: to save water
•
To consume less water, stop the washing and rinsing procedure as soon as the water is no longer cloudy
in the transparent window on the side of the multiway valve.
