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 showerhead position 
of at least 1 metre.
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.
Flushing Pipe-work
Important: Before connecting the 
shower valve (see ‘Installation’ on pages 
16-17), supply pipe-work must be flushed 
to clear debris before connecting the 
shower valve. Debris will reduce the 
performance and life of the shower.
