Gravity Fed Hot and Cold
Important: If you install this shower
valve with a gravity fed system, there must
be a minimum head (vertical distance)
from the underside of the cold water
storage tank to the shower valve position of
at least 5 metres.
Note: Pumped system (with Essex
flange) If you install this shower valve to a
pumped gravity fed system where the
minimum head (vertical distance) from the
underside of the cold water storage tank to
the top of the hot water cylinder is less
than 1 metre we recommend an Essex
flange is used as shown on page 09.
Flushing Pipework
Important: Before connecting the
shower valve (see Installation on pages 12-
14), supply pipework must be flushed to
clear debris before connecting the shower
valve. Debris will reduce the performance
and life of the shower.
