5 - Installation procedures
5.1 - Assembly prior to installation
The filter is normally supplied fully assembled.
Electrical connections will be done by authorized personnel only.
The filter may be installed in any position, although for ease of maintenance, horizontal installation is
recommended.
5.2 - Filter installation
1. For best results, the filter should be installed as near as possible to the system it is required to protect. However,
if low filter inlet pressure is a concern, either before or during flushing, the filter may need to be installed closer
to the pressure source.
2. Ensure that the upstream pipe size from the pressure source to the filter is equal to or greater than the filter's
inlet size.
3. It is strongly recommended to install an isolation valve at the filter's inlet, and a check valve, or an isolation
valve at the filter's outlet.
4. An inlet isolation valve must be installed in situations where the pressure source cannot be shut down for
maintenance.
5. Inlet/outlet and by-pass valves must be installed in situations where a constant supply of water is required
downstream during filter servicing.
6. Ensure that the filter is mounted in the proper flow direction, as indicated by the arrows on the filter housing. As
a check, the inlet is closer to the cover end of the filter.
7. If a fixed drain pipe is installed on the auxillairy filter, use a funnel or other means so it will be visible if the valve
is opened or closed.
8. The mounting of the delivered 1"airvalve is strongly advised.
9. Ensure that sufficient space is provided around the filter for maintenance.
10. When the screen element is disassembled, reassembly as follows. Insert the screen element inside the filter
body. Open the service port cover (6) in order to get easy access to place the collector assembly in place. The
drive shaft (39) must be inserted into the shaft guide (19). Before doing so apply grease to the drive shaft.
11. When an acid-base injection is installed the injection location should be downstream from the filter.
Part numbers refer to the illustrated parts breakdown in chapter 11
5.3 - Drain line installation
A drain line should be attached to each flushing valve, as follows:
● The back pressure at the flush valve outlet should not exceed 0.3 bar (4.5 psi)
● Piping should be installed level or pitch down to avoid back-pressure.
● The open end of piping should be securely mounted to avoid vibrations during flushing cycle.
