Hydraulics The user should install a manual water cut-off valve 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. ...
Changing Installation Configuration Changing the inlet/outlet direction: If the original configuration does not match the required installation position, the lower body can be rotated 360°. In order to change the configuration of the filter, follow these steps: 1. Disassemble the filter according to "Basic Maintenance Disassembly" (on page 14) 2.
