3 - INSTALLATION PROCEDURES
3.1 - Assembly prior to installation
The filter is normally supplied fully assembled.
Electrical connections will be done by authorized personnel only.
Install the filter only in vertical position.
3.2 - 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. A pressure relief valve must be installed before the filtering installation if the pressure is not controlled
effectively.
4. 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.
5. An inlet isolation valve must be installed in situations where the pressure source cannot be shut down
for maintenance.
6. Ensure that the filter is mounted in the proper flow direction, as indicated by the arrows on the filter
housing.
7. Ensure that sufficient space is provided around the filter for maintenance.
3.3 - 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 3 meters (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 fluttering during flushing cycle.
