Fitting the Knob Assembly
1. Screw the locknut onto the headnut
until it firmly locks the concealing plate
in place. Make sure that the 'O' seal
is fitted to the locknut for a watertight
seal between the locknut and
concealing plate.
Note! Do not overtighten the locknuts
or the concealing plate will deform.
2. Refit the locknut trim. Make sure that
the trim is fitted the correct way round
(see illustration).
3. Fit the control knob inner bush so the
securing grub screw aligns with the
spindle flat. Tighten the grub screw
with the 2.5 mm hexagonal key
provided. Make sure that the inner bush
'O' seal is fitted for a watertight seal
between the inner bush and the
locknut.
4. Rotate the inner bush fully clockwise
for the flow control or fully
anticlockwise for the temperature
control. Refit the control knobs (see
illustration) and secure with the lever
screw and the lever cover.
Note! The lever screw needs to be
secured with a spanner. Do not
overtighten the lever screw as product
damage may occur.
Note! If the control knobs are
incorrectly fitted the levers may foul
against each other when in use.
5. Check the control knobs can be rotated
fully and the full flow and temperature
range can be selected.
