a) Water too HOT
Water flow restricted by blockage in filter of
solenoid valve. Switch off water and undo plastic
nut on elbow, loosen brass nut to swing elbow
away from solenoid. Remove filter in solenoid with
long nosed pliers and flush clean.
b) Water too COLD
Check circuit through thermal cut-out
Check circuit through microswitch on the pressure
switch
Check each element circuit.
Check tightness of electrical connections.
c) Water leaks from burst pressure relief
valve
Check for cause of high pressure and remove it.
i.e. Blockage on outlet or blocked spray plate.
Replace the pressure relief disc.
d) Water does not flow when Knob “A” is
rotated (when button “C” is pressed -
620 only)
Check the circuit through the solenoid coil.
Check circuit through mini microswitch (push switch
– 620 only)
Possible timer PCB fault (620 only). If defective,
then replace.
Power supply not reaching shower.
Installation instructions
Check that the electrical rating shown on the shower matches the mains supply.
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

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.
