THIS INSTALLATION AND USER GUIDE IS DESIGNED TO ENSURE THE SAFETY OF THE INSTALLER AND USER AND THE
OPERATION/RELIABILITY OF THE PRODUCT. FAILURE TO OBSERVE THESE MAY CAUSE A HAZARD, DAMAGE THE PRODUCT AND
INVALIDATE YOUR GUARANTEE.
Safety information
This product must be installed by a competent person in accordance with all relevant current water supply regulations.
The electrical installation should be carried out by a qualified person in accordance with IEE (Institute of Electrical Engineers) wiring
regulations (BS 7671) and certified to current building regulations. With reference to building regulation Part P, any new installation
or replacement product installation which is not identical to the product being replaced, the cable sizes, circuit protection devices,
earth bonding and all other requirements of the building regulation must be assessed by a (registered) qualified electrician and
installed to the site conditions (see table in electrical rating).
THIS APPLIANCE IS NOT INTENDED FOR USE BY PERSONS (INCLUDING CHILDREN) WITH REDUCED PHYSICAL, SENSORY OR
MENTAL CAPABILITIES OR LACK OF EXPERIENCE AND KNOWLEDGE UNLESS THEY HAVE BEEN GIVEN INITIAL SUPERVISION OR
INSTRUCTION CONCERNING THE USE OF THE APPLIANCE BY A PERSON RESPONSIBLE FOR THEIR SAFETY. CHILDREN SHOULD BE
SUPERVISED TO ENSURE THAT THEY DO NOT PLAY WITH THE APPLIANCE.
THE GAINSBOROUGH SHOWER IS SUITABLE FOR HOUSEHOLD USE ONLY
Connections
This shower unit is designed for use with 15mm British Standard pipe and suitable for top, bottom or rear entry pipe work and cable
connections. Supply lines should be flushed clear of any debris prior to installation of the unit.
Isolating valves
A suitable full bore isolation valve must be fitted to the incoming supply in accordance with the current water supply regulations and
our terms of warranty.
Siting
The unit must be mounted on a flat, vertical finished wall with the hose pointing downwards. Any distortion of the back plate may
result in the unit not working. Spacers are provided to enable the unit to be fitted to an uneven wall surface.
DO NOT tile up to or use sealants around the unit. The shower is spaced off the wall by integral pillars to allow air circulation around
the unit.
The casing must not be sited where it is subject to continuous spray from the shower head.
The unit must not be sited where it is likely to freeze.
WARNING: DO NOT SWITCH THE SHOWER ON IF THERE IS A POSSIBILITY THAT THE SHOWER COULD BE FROZEN. IF YOU HAVE
SWITCHED THE SHOWER ON, SWITCH OFF IMMEDIATELY (Please refer to the troubleshooting guide page 14).
Pressures
Check that the dynamic (running) water pressure to the electric shower is adequate.
The required dynamic (running) pressure is:-
Maximum 1.0MPa (10 Bar)
Minimum 0.09MPa (0.9 Bar) at a flow rate of 8 litres per minute
Where pressures are likely to exceed 1.0MPa (10 bar), a pressure reducing valve must be fitted to the incoming mains supply. A
setting of 0.3MPa (3 bar) is recommended. It should be noted that daytime pressures approaching 8 bar can rise above the stated
maximum.
The use of other services connected to the water supply to the shower unit may cause the water pressure to drop below the
minimum required. This should therefore be taken into consideration.
