6. All plumbing connections must be
completed before making the electrical
connections.

The following points will help you to
understand how your Dimplex shower unit
operates.
The ow rate of water passing through the
shower unit determines the water temperature.
The lower the ow the warmer the water, the
higher the ow the cooler the water.
The temperature produced by the shower
unit will vary between seasons on any one
setting of the temperature control. This is due
to variance in the temperature of the water
supply, which becomes cooler in winter than
summer.
The stabiliser valve maintains an almost
constant shower temperature during mains
water pressure changes.
If changes in temperature are experienced in
normal use, it is likely to be caused by water
pressure falling below the minimum level. Falls
in water pressure may be due to water being
drawn off at other points within the building.
The shower head must be cleaned regularly to
remove scale and debris. If the water becomes
hot and you are unable to obtain cooler water,
check the shower head for blockage.

ow until the unit has cooled sufciently. Power
to the elements will be automatically restored.
If the Auto Reset Neon Indicator persistently
functions, ensure that the shower head is free
from scale and debris which will increase the
ow of water through the unit.
SECTION 12
Shower head cleaning instructions
IN SHOWER MAINTENANCE
To break away scale
deposits on a daily basis
simply rub your thumb over
the rubber nipples whilst the
shower is running.
The shower head should be cleaned
periodically to remove limescale or debris
which will reduce the performance of the
shower. The frequency of cleaning will vary
according to local water quality. In hard water
areas cleaning will be needed more often
than in soft water areas. A liquid non-abrasive
bathroom cleaner may be used on external
surfaces of the handset.

Plan your own installation carefully. Check on
the nearest and most readily accessible rising
mains water supply, this may be beneath the
bath or in the loft, where it feeds the cold
water storage tank. Use only the cold rising
water main supply.
Do not connect the shower unit to the
down service from the tank.
Avoid connecting the shower unit, if possible,
were it will be affected by water drawn off by
other appliances, e.g. From the mains feed to
the W.C., This may cause a drop in pressure
too low for the shower unit to work correctly.
An isolating valve must be tted into the water
supply for servicing purposes. Remove the two screws securing the shower
unit cover and remove the cover complete with
the control knobs.
Place the shower unit on the wall and mark the
location of the xing screws through the back
plate.
Carefully drill the holes as marked using a
sharp 5.5mm masonry drill.
Fix the shower unit to the wall using the plugs
and screws provided, do not fully tighten at
this stage.

IMPORTANT
To comply with National Water Council bylaws
a double check valve must be tted with all
exible shower accessories where it is possible
that the shower head may come into contact
with used water i.e. in the bath or shower tray.
SECTION 5
Plumming connection
Plumbing the shower unit must precede
wiring.
Turn off the water supply at the isolating stop
tap.
Having determined the direction of the inlet
water supply: Top (falling), Bottom (rising),
or Back inlet. It is necessary to remove the
appropriate plastic cross section from the back
plate, before commencing with the installation
(See diagrams Fig 1 & Fig 2).
PLUMMING CONNECTION
5
The back plate is tted with removable inserts
for Top (falling) and Bottom (rising) inlet mains
water pipework to the shower unit.
We have incorporated into the bottom right-
hand side of the back plate an easy removable
trim section, to allow easy access when
connecting the water supply.
(Please Note! Remember to replace this trim
section before retting the cover).
Remove this plastic
cross-section when using
the ‘REAR’ or ‘TOP’ entry
point for plumming
Remove this plastic
cross-section when using
the ‘BOTTOM’ entry point
for plumming
Connect the mains water supply to the inlet
of the shower unit using a 15mm copper or
stainless pipe with a 15mm compression
elbow or 15mmm push-t elbow. Do not
use excessive force when making the
connection to the unit.
IMPORTANT
Before turning on the water supply to the
shower unit the water supply pipe should be
ushed out to remove debris. This can be
achieved by connecting the exible hose to the
15mm compression elbow and turning on the
mains water supply long enough to clear the
debris.
After ushing the pipework ensure that the
shower unit is positioned squarely on the wall
and tighten the screws. Tighten all plumbing
connections and check the pipework for leaks.
