INTRODUCTION
This book contains all the necessary tting and
operating instructions for your Triton mixer
shower. Please read them carefully and read
through the whole of this book before beginning
your installation.
The shower installation must be carried out by
a suitably competent person and in sequence of
this instruction book.
Care taken during the installation will give a long
and trouble free life from your mixer shower.
SITE REQUIREMENTS
The installation must be in accordance with
water supply (water ttings) regulation 1999
and/or local Bylaws.
Water pressure requirements
Running water pressure:
Low presure - 0.1 bar min.
1.0 bar max.
High pressure - 0.5 bar min.
5.0 bar max.
Maximum static water pressure:
Low & High pressure - 10 bar
This mixer shower is designed for use with
traditional low pressure ‘gravity’ water systems,
using a cold water cistern and hot water cylinder
as well as for the higher pressure systems found
in the UK up to a maximum of 5 bar running
pressure.
For effective operation of the internal seals, the
maximum static pressure must not be exceeded.
Pressure reducing valve
On sites where the running pressure is above 5
bar, the use of a suitably sized pressure reducing
valve tted in the cold mains supply pipe work
can provide nominally equal pressures at the
mixer shower.
Water minimum ow rate
For best performance within the specied running
pressure range a minimum ow of 8 litres per
minute should be available to both inlets.
Water temperature requirements
Maximum hot water temperature: = 80°C
Recommended maximum: = 65°C
Minimum hot water temperature: = 55°C
Maximum cold water temperature: = 25°C
NOTE: Valves operating outside these conditions
cannot be guaranteed by the Scheme to operate
as Type 2 valves.
The mixer shower MUST NOT be subjected to
water temperatures above 80°C.
BS 6700 recommends that the temperature of
stored water should never exceed 65°C.
A stored water temperature of 60°C is
considered sufcient to meet all normal
requirements and will minimise the effects of
scale in hard water areas.
Water temperature adjustment and
thermal safety
The mixed water temperature can be adjusted
from cold through to a top limit which must
be preset during installation with full anti-scald
protection throughout the range (35°C to 40°C)
providing the hot water temperature at the inlet
remains 10°C above the outlet temperature.
Should there be a loss of ow to either incoming
supply then water from the shower will stop or
be reduced until both supplies are restored.
SAFETY WARNINGS
a. DO NOT choose a position where the shower
could become frozen.
b. DO NOT connect this mixer shower to any
form of tap or tting not recommended by
the manufacturer.
c. DO NOT allow the inlet pressure or ow
rates to operate outside the guidelines laid
out in ‘site requirements’.
d. DO NOT connect the mixer shower to a
gravity hot supply and a mains cold supply or
vice versa.

PLUMBING REQUIREMENTS
DO NOT use jointing compounds on any pipe
ttings for the installation.
DO NOT solder ttings near the mixer unit
as heat can transfer along the pipework and
damage the mixer valve.
IMPORTANT:
• The layout and sizing of pipework MUST
be such that nominally equal inlet supply
pressures are achieved and the effects of
other draw-offs are minimised.
• The pipework should be installed such
that other taps and appliances being
operated elsewhere on the premises do not
signicantly affect the ow
• When connecting pipework avoid using tight
90° elbows; swept or formed bends will give
the best performance.
• The hot water pipe entry must be made to
the left-hand side inlet, marked HOT, ‘H’ or
with a red/orange label.
• Suitable isolating valves (complying with
Water Regulations and Bylaws) must be tted
on the hot and cold water supplies to the
shower as an independent means of isolating
the water supplies should maintenance
or servicing be necessary. If this isolator is
tted in a loft space, the loft must have a
xed access ladder and be boarded, with
appropriate lighting from the access point to
the isolator.
• It is preferable to ush the pipework to clear
the system of debris and check for leaks
before connecting to the mixer.
• The mixer inlets contain removable lters
that may become blocked if debris is not
ushed through before tting.
Commercial applications
• Triton recommends for all commercial
applications that, easily accessible, in-line
lters are used to aid maintenance.
Hard water areas
a. If it is intended to operate the shower
in areas of hard water (above 200-ppm
temporary hardness), a scale inhibitor may
have to be tted. For advice on the Triton
scale inhibitor, please contact Customer
Service.
b. For best performance the showerhead MUST be
regularly cleaned to remove scale and debris.
WATER SYSTEM REQUIREMENTS
This mixer shower is suitable for:
• Gravity water systems
• Pumped gravity systems
• Fully modulating type combination boilers
• Multi-point hot water heaters
• Thermal storage
• Unvented systems
When installing this mixer with a combination or
multi-point boiler, it may be necessary to install
ow regulation.
Check that the appliance is capable of delivering
hot water at a minimum switch-on ow rate
of 3 litres per minute. At ow rates between 3
and 8 litres per minute, the appliance must be
capable of raising the water temperature to 52°C
minimum.
Water temperature at the inlet of the mixer valve
must remain relatively constant when ow rate
adjustments are made (refer to the appliance
operating manual to conrm compatibility with
this mixer shower).
Where thermal store systems and instantaneous
gas water heaters are used, if excessive draw-off
takes place the appliance may not be able to
maintain an adequate output temperature. This
could result in the shower temperature becoming
noticeably cooler.
Flow regulators can be tted with high-pressure
water systems to reduce ow rate and assist
economy.
The hot supply temperature MUST remain a
minimum of 10°C hotter than the required blend
temperature for optimum performance.
