SPECIFICATION
European Conformity Information
This range of electric showers complies with the following
European directives:
2006/95/EC Low Voltage Directive, 2004/108/EC EMC
Directive
, 2011/65/EU RoHS Directive
This range of electric showers are high power appliances and
are subject to conditional connection. If the main electrical
supply fuse is rated less than 80 Amps, the local electricity
supply company must be contacted to confirm if the electrical
supply is adequate.
This range of showers complies with the requirements of the
UK’s water regulations.
PLUMBING
1. The plumbing installation must comply with all national
or local water regulations and all relevant building
regulations, or any particular regulation or practice
specified by the local water supply company.
2. Do not install the product in a position in which service
access is limited.
3. Decide on a suitable position for the shower (minimum
distance of 200 mm from the ceiling to allow for cover fit
and removal).
4. The shower is suitable for installation within the shower
area and is fitted with a pressure relief valve. It must be
positioned over a water catchment area with the controls
at a convenient height for the user.
5. The shower must be fitted to a waterproof flat and even
wall surface.
6.
DO NOT
fit the shower to the wall and tile up to the case.
7.
DO NOT
seal the gap between the shower and the wall
surface.
8. The showerhead should be positioned so that it
discharges down the centre line of the bath or across
the opening of a shower cubicle.
9. The showerhead must be directed away from the shower
unit, during normal use the showerhead must not spray
directly on to the shower unit.
10.
DO NOT
apply excessive force to plumbing connections;
always provide mechanical support when making
plumbing connections. Any soldered joints should be
made before connecting the shower.
11. The position of the shower and shower fittings must
provide a minimum gap of 25 mm between the
showerhead and the spill over level of any bath, shower
tray or basin and a minimum gap of 30 mm between the
showerhead and the spill over level of any toilet, bidet or

Note!
There will be occasions when the hose retaining
ring will not provide a suitable solution for Fluid Category 3
installations, in these instances an outlet double checkvalve
must be fitted, this will increase the required supply pressure
typically by 10kPa (0.1 bar). Double checkvalves fitted in the
inlet supply to the appliance cause a pressure build up, which
affect the maximum static inlet pressure for the appliance and
must not be fitted. For Fluid category 5 double checkvalves
are not suitable.
12. This shower is not designed to be plumbed directly from
the rear. For rear-entry supply, add an elbow to the supply
pipe and connect as a rising or a falling supply.
