Flow Restrictors (Mini, Midi & Digifiller models only)
Pressurisation equipment fitted with a plastic, side-entry torbeck valve must be fitted
with a filter and – depending on the mains water pressure – a flow restrictor. Failure
to do this may result in damage to the equipment.
Two different flow restrictors are supplied with the equipment, both of which include an integral
filter. The selection of the appropriate flow restrictor is based on the maximum mains water
pressure at the point of installation. Please refer to the following table for selection.
Low Pressure Restrictor (coloured)
High Pressure Restrictor (white, factory fitted)
If no restrictor is required, the filter must be removed from one of the restrictors and installed on its
own. The following diagram shows how to remove the filter:
To install the flow restrictor/filter, hold it by the tab and push it into the opening of the float valve
connection, as shown in the diagram below:
