➢
The user should install a manual water cut-off v alve next to the filter’s inlet port.
➢
In installations where the piping network downstream of the filter is pressurized, an additional
manual water cut-off valve should be installed next to the filter's outlet port.
➢
The user should make sure that the system includes a pressure release / drainage valve to enable
release of residual pressure prior to any maintenance procedure is performed on the filter.
➢
The user should make sure that the filter is never exposed to water pressure exceeding the
maximum designated pressure for this filter. When necessary, a pressure reduction valve should
be installed upstream of the filter’s water inlet port.
➢
Please note that the maximum working pressure indicated in the filter’s specifications table
includes the pressure caused by fluid hammer and pressure surge effects.
➢
If possible, prior to installing the filter, thoroughly flush the main line at the connection point in
order to remove large objects that may damage the filter’s internal mechanism.
Important installation note
➢
Install the filter vertically. Please note that a minimum clearance of 70 cm (27") is required in order
to disassemble the unit.
Attention
➢
Ensure that the direction of the flow is aligned with the arrows marked on the filter housing.
➢
To prevent static backpressure or reverse flow through the filter, it is recommended to install a
non-return valve.
