The installation must be in accordance with Water Regulations/Bylaws.
WATER REQUIREMENTS
Supply Source ............................................ Gravity fed cold water only
Minimum Head
.......................................... 8cm
Maximum static pressure ........................... 100 kPa (1 bar) or (10m Head)
Maximum inlet temperature
...................... 28°C
Minimum inlet temperature
....................... 2°C
To ensure activation of the heating elements,
the shower must be connected to a cold water
supply which is Gravity Fed Only from a static
cold water storage cistern with a minimum
capacity of 114 litres (25 gallons).
There must be a maximum head of water of
10 metres and a minimum head of 8 cm as
measured between the bottom of the cistern and
the top of the shower unit. There must be no
other cold water draw-offs between the cistern
and the unit and the pipe must not supply water
to any other tap or fitting at a lower level.
Note: The supply pipe from the cistern should be
on the opposite side to the float operated valve
to prevent air being drawn into the pipe when
the cistern is filling.
If it is intended to operate the shower in
hard water areas (above 200 ppm temporary
hardness) a scale inhibitor should be fitted.
Fig.5 shows a typical system layout.
DO NOT use jointing compounds on any pipe
fittings for the installation.
WARNING!
Under no circumstances must
this shower be connected directly
to the mains water supply.
