A competent installer must undertake all installations. If in any doubt, advice and 
assistance should be sought from a qualified plumber and/or electrician. Installations and 
wiring must conform to current IEE regulations (UK) BS7671 
 
WARNING! DO NOT INSTALL THIS SHOWER IN A ROOM WHERE IT MAY BE SUBJECT TO 
FREEZING 
 
We recommend that the installation be done in the following sequence. 

a)  Fixing the shower to the wall 
b) Plumbing 
c) Electrical connections 

1.  Position the riser rail at the height recommended in 

diagram 5 and mark its position. 

 

2.  Position the heater so the sides of the unit are vertical 

and the top is level with, or up to 0.6 metres (2ft) 
maximum below the top of the riser rail. Choose a flat 
piece of wall to avoid the possibility of distorting the back 
plate thus making the front cover a poor fit 

 
3.  Adjust the positions to get the most convenient 

arrangement taking the following into account. 

 

a)  The possible need to use the handset over the sink 

for hair washing etc. 

 

b) The 

heater 

must not be mounted in the direct spray 

from the showerhead.
