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
a) Fixing the shower to the wall
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.
