Strainers
To ensure trouble free operation of the fitting, the strainer elements should be checked and cleaned in
accordance with the commissioning and servicing guide (See section 7 and 9).
To access the strainer element, first slide forward the shrouds and close the isolation valves. Unscrew the
connection nut using metric spanner 30mm and detach the unit from the wall. See section 9.2 for the
assembly drawing to locate the strainer. The strainer element should be washed with clean water and refitted.
