Electric wiring
1.
All electrical works at the installation site must be done by a qualified and authorized electrician only.
Make sure that this electrician is fully aware of all the relevant safety instructions.
2.
Install the control board in a dry and protected place (In out-door installation sites make sure to use a
special control board for out-door installation).
3.
Power connection to the control board:
a.
Connect a three-phase voltage source through a semi-automatic switch, or 16 Amp. fuse to the L1 L2
L3 inlet at the terminal strip in the control board.
b.
Earth the control board.
4.
Power connection to the motor:
Connect the drive unit to the control panel by means of a 4 x 2.5 mm (12 or 14 AWG) wire in flex-conduct.
Use a long enough cable to allow the drive unit to be removed and placed near the filter for maintenance,
without having to disconnect it from the cable. (It is recommended that this installation meets or exceeds
local or national electrical codes, this is a "high" voltage connection).
5.
Control wiring:
The connection between the control junction box and the control board should be by 6 x 1.5 mm 2 (16
AWG) wire in flex-conduct. The numbers on the terminals in the board and in the junction box are identical.
COMMISSIONING, START-UP AND FIRST OPERATION
1.
Before starting-up the filter read the safety instruction as appear at chapter 2 of this document and pay
special attention to the commissioning safety instructions.
2.
Inspect the filter’s installation and make sure that it is installed in accordance with the official installation
drawings.
3.
Verify (by authorized electrician only) that the electric wiring is correct and complies with the enclosed
drawings. Make sure that the electrical start-up operation is done by an authorized electrician only.
4.
Switch the control & 24V circuit breakers. Leave the motor OL protector OFF.
5.
Toggle all limit switches to verify that they activate the correct inputs on the PLC according to the wiring
schematic. Correct connections, if necessary, before proceeding to the next step.
6.
Switch ON the motor protector O.L. The motor will start operating.
The suction scanner shaft should turn clockwise and move downward to the filter housing until it reaches
the lower limit switch. If the motor rotates in the opposite direction, disconnect the electricity immediately
and change the direction of the motor rotation by changing between two phases.
The motor must stop when the limit switch plate reaches the lower limit switch and causes it to operate.
7.
Operate a "dry" flushing cycle by pressing on the "TEST" push button. Make sure all flushing stages occur
as described in the filter description chapter of this manual.
8.
Open the inlet valve to the filter, while the outlet valve remains closed or with an open by-pass valve (This
will keep the flow in the filter at a minimum), and operate a flushing cycle.
Make sure the exhaust valve opens and all stages of the flushing cycle are carried out. Attend to leakage,
if any.
9.
Gradually open the outlet valve and/or close the by-pass valve. Operate the filter at the designed hydraulic
conditions.
10.
Set the timer for 6-8 hours.
11.
Check and re-tighten all bolts after the first week of operation.
