Important Safety Information
WARNING! This shower can deliver scalding temperatures. For
continued safe operation, follow all instructions, warnings and
cautions contained in this guide and on or inside the shower.
Periodic maintenance may be required to keep the product in
good working order.
The function of a thermostatic mixing valve is to deliver water
consistently at a safe temperature. In keeping with every other
mechanism, it cannot be considered as functionally infallible and
as such, cannot totally replace a supervisor’s vigilance where that
is necessary. Provided it is installed, commissioned, operated and
maintained within manufacturers recommendations, the risk of
failure, if not eliminated, is reduced to the minimum achievable.
PLEASE OBSERVE THE FOLLOWING TO REDUCE THE RISK OF
INJURY:
INSTALLING THE SHOWER
1. I nstallation of the shower must be carried out in accordance with
these instructions by qualified, competent personnel. Read all
instructions before installing the shower.

Suitable Plumbing Systems
Gravity Fed:
The shower must be fed from a cold water cistern (usually located in the loft space)
and a hot water cylinder (usually located in the airing cupboard) providing nominally
equal pressures.
Gas Heated System:
The shower can be installed with a combination boiler provided the hot and cold
water supply pressures are balanced when entering the shower.
Unvented Mains Pressure System:
The shower can be installed with an unvented, stored hot water system.
Mains Pressurised Instantaneous Hot Water System:
The shower can be installed with systems of this type with balanced pressures.
Pumped Systems:
The shower can be installed with an inlet pump (twin impeller). The pump must be
installed on the floor next to the hot water cylinder.
General
1.
Installation of the shower must be carried out in accordance with these instructions
by qualified, competent personnel.
2.
he plumbing installation must comply with all national or local water regulations and
T
all relevant building regulations, or any particular regulation or practice specified by
the local water supply company.
3.
ake sure all pressures and temperatures comply with the requirements of the shower.
M
See “Specifications”. For Type 2 Valves, refer to supply conditions given in the TMV2
Requirements Manual.
4.
ull bore / non restrictive servicing valves must be fitted in a readily accessible position
F
adjacent to the shower to facilitate maintenance of the shower.
DO NOT use a valve with a loose washer plate (jumper) as this can lead to a build
up of static pressure.
5.
DO NOT apply excessive force to plumbing connections; always provide mechanical
support when making plumbing connections. Any soldered joints should be made
before connecting the shower.
6.

Note! There will be occasions
when the hose retaining ring
will not provide a suitable
solution for Fluid Category 3
installations. In these instances
an outlet double checkvalve
must be fitted, this will increase
the required supply pressure
typically by 10 kPa (0.1 bar).
Double checkvalves fitted
in the inlet supply to the
appliance cause a pressure
build up, which affects the
maximum static inlet pressure
for the appliance and must not
be fitted. For Fluid Category 5,
double checkvalves are not
suitable.

10. P
osition the shower unit where the controls are at a convenient height for the user.
Position the showerhead so that the water sprays in line with the bath or across the
opening of a shower cubicle. The showerhead must not spray directly onto the shower
unit during normal use. The installation must not cause the shower hose to be kinked
during normal use.
11. T
he water supplies to this product should be isolated if the product is not to be used
for a long period of time. If the product or pipework is at risk of freezing during this
period they should also be drained of water.

Flow Regulators
The shower unit is fitted with a 12 L / min (red) flow
regulator. This may be changed to the 6 L / min
(black) supplied.
We recommend the following as a general guideline for water
pressures:
12 L / min (red) for maintained (running) water pressure greater
than 0.5 bar. To help resolve issues such as:
1.
Excessive shower force.
2.
Noise due to high or unequal water pressure.
3.
Unstable supply temperatures.
6 L / min (black) for maintained (running) water pressure greater
than 0.5 bar to conserve the most water while showering.
Note! The flow regulator may affect the performance of some
combination boilers while the shower is running. Check with
the boiler’s manufacturer before fitting the flow regulator.
Remove the flow regulator if the maintained (running) water pressure is less than 0.5 bar or the shower
force is too low.
