INSTALLATION
Design recommendations:
1. Often, flow increases and pressure drop dramatically during fill-up of a water system. In this case, a pressure-sustaining
valve installed downstream of the filter will ensure the minimum required pressure for the filter and a controlled filling-up
of the line.
2. If constant water flow is required even during maintenance, it is recommended that a manual or automatic by-pass be
installed. Isolating valves will be used to isolate each filter unit.
3. In applications where the water quality periodically worsens, it is possible to operate an emergency flush program. In order
to do so, an automatic Down Stream valve must be installed. For details, please consult the manufacturer.
Installation instructions:
1. Install the filter horizontally in a manner that will allow convenient access and enough space to dismantle the filter for
maintenance purposes.
2. Check the direction of flow according to the arrows marked on the filter housing.
3. It is recommended to install a mechanical non-return valve downstream of the filter.
4.
The exhaust line (minimum 2”
diameter) should be designed so that it creates minimal resistance to flow of 11 m3/h (50
USgpm).
5. If the system is designed to operate with working pressure higher than 6 bar (85 psi), it is recommended that a manual
throttling valve be installed on the exhaust line, in order to enable regulation of the flushing flow rate.
6. The user should arrange suitable lighting at the area of the filter to enable good visibility and safe maintenance.
7. The user should arrange suitable platforms and safety barriers to enable easy access to the filter without climbing on pipes
and other equipment.
IMPORTANT !!
Prevent static back-pressure or reverse flow through the filter.
Install a manual or a hydraulic valve downstream of the filter.
Electric wiring
1.
Install the control board in a dry and protected place (It is possible to order a special control board for severe out-door
installation).
For single phase or DC power supply, please refer to the electrical drawing inside the control board.
2.
Power connection to the control board:
a. Connect a three-phase power source through a semi-automatic switch, or 16 Amp. fuse to the L1 L2 L3 connectors at the
terminal strip in the control board.
b. Ground the control board.
3.
Power connection to the motor:
Connect the drive unit to the control panel using 4 x 2.5 mm (12 or 14 AWG) wires in flex-
conduct. Use a long enough cable to allow removal of the drive unit and placing it near the filter for maintenance, without
having to disconnect it from the cable. (The installation should meets or exceeds local or national electrical codes for "high"
voltage).
4.
Control wiring:
Connect the terminals between the junction box and the control panel using 6 x 1.5 mm (16 AWG) wires in
flex-conduit. The numbers on the terminals in the board correspond with those in the junction box.
