8. Starting-up
The starting-up of the unit consists of running a first regeneration cycle, during which the
filtering media column will be filled of water, all automatic features will be checked and the unit
will be prepared to start the service.
At the beginning, it is suggested to operate manually, and to hand-driven the valves, by
hand-driving the lever of the pilot solenoid valves:
the solenoid valve is closed when the lever is on parallel to the base and it is open
when it is on perpendicular to the base itself.
This way will allow to stop, to run for longer time or to repeat each phase as desired, and to
adjust the flow rates according to the attached table.
To start-up the unit, proceed as follows (for DUAL arrangement, operate on column A only):
•
DISCONNECT ELECTRIC POWER
•
shut off the inlet, outlet and by-pass gate valves.
•
close quite completely the gate valve along the backwash drain line
•
hand-drive the solenoid valves E3 to open the backwashing membrane valves
•
open slowly and only partially the gate valve on inlet line. The water will enter inside the
vessel from the bottom and, during filling, will expel the air inside it.
•
when only water will come out from the drain, open completely the inlet gate valve and adjust
the backwash drain gate valve in order that the flow rate will be the highest allowable without
any leakage of media filter through the drain line; when the proper flow rate of backwash has
been stated, adjust the gate valve definitely. The backwashing phase must run until all the
water coming out the drain is perfectly clear.
•
Hand-drive the solenoid valves E3 to close the backwashing membrane valves.
•
Hand-drive the solenoid valve E1 to open the membrane valve V1 (RINSE); the rinse phase
must run until all the water coming out the drain is perfectly clear.
•
Hand-drive the solenoid valves E1 to close the valve V1 and to conclude the regeneration.
•
Switch ON the control panel.
•
Open the outlet valve .
Starting now the unit is on service and feeds treated water.
For DUAL arrangement : repeat all listed operation on column B
It is suggested to check, during the running of the first automatic regenerations, that the
adjusted flow rates and times are correct.
