The table on page 12 shows the flow regulator requirements and valve adjustments for
various hot / cold supplies.
# Flow regulators are fitted and will be required to be removed when installed in low
pressure (gravity fed) applications below 1.0 bar. To remove: unscrew the retaining ring
and remove regulator and washer. Re-fit elbows back to the body.
* With certain permutations of combi-boiler hot supply and cold supply, it must not be
necessary to fit the flow regulator on the hot supply.
** The bottom cap is factory set at 3/4 turn from
the fully closed position. Only adjust if instructed
to do so in the table on page 12 or when fitting a
replacement cartridge assembly. (See maintenance
section. Remove mixing valve from backplate (see
Installation). Peel of label to reveal bottom cap, with a
marker pen, mark a point in-line with the slot. Turn an
extra 1/2 turn (180º) turn using a screw driver.

Important: It is a requirement of Instantaneous Electric Water Heaters that a
stable flow of water passes through the heater. This requirement can be satisfied by
using a flow stabiliser in the supply to the heater. It should be adjusted to give a flow
temperature of 45-50ºC from the heater.
