9. – START-UP INSTRUCTIONS
Check the items in the section above.
Check the hydraulic circuit (see section 14) which brings water to the flush valve, making
sure that:
o
The filter is clean.
Begin with the following settings in the shut-off valves:
o
Inlet valve: OPEN.
o
Outlet valve: CLOSED.
o
By – pass (if any): CLOSED.
Connect the filter to the power supply.
Force a manual cleaning by pressing the manual cleaning button.
Open the outlet valve.
During filling from the network both a pressure drop and an increased flow rate occur, this
makes it desirable to install a pressure sustaining valve at the output, thus ensuring a
controlled filling from the network.
NOTE
IF NO PRESSURE SUSTAINING VALVE IS INSTALLED, CLOSE THE
OUTLET VALVE DURING FILLING FROM THE NETWORK UNTIL 2 BAR IS
REACHED IN THE CLEAN WATER CHAMBER GAUGE. ONCE THE
NETWORK IS PRESSURIZED, OPEN THE OUTLET VALVE OPEN FOR
PROPER OPERATION.
Make sure that the system flow rate and pressure match the maximum ones defined for
the specific model in this manual. See section 6.
Check correct operation and load loss generated by the device once the start-up has
been completed.
NOTE
THE FILTER MAY AUTOMATICALLY START THE CLEANING CYCLE
WHEN DIFFERENTIAL PRESSURE BETWEEN THE INPUT AND OUTPUT
IS HIGHER THAN 0.3 BAR.
