Dual control thermostati c mixer

INTRODUCTION

This book contains all the necessary fitting and
operating instructions for your Triton Antares
dual control thermostatic mixer shower. Please
read them carefully. Read through the whole of
this book before beginning your installation.

The shower installation
a suitably competent person and in sequence of
this instruction book.

Care taken during the installation will provide a
long and trouble free life from your shower.

For best performance within the specified
running pressure range a minimum flow of eight
litres per minute should be available to both
inlets.

The mixer shower MUST NOT be subjected to
water temperatures above 80°C.

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.

IMPORTANT

with combination and multipoint hot water
appliances, the supplied flow restricters
MUST be installed.

This mixer shower is suitable for fully
modulating type combination boilers and multi­point hot water heaters. It is also suitable for
thermal storage, unvented systems and pumped
gravity systems.

IMPORTANT

instantaneous water heater, make sure it is
capable of delivering hot water at a minimum
switch-on flow rate of 3 litres per minute. At
flow rates between 3 and 8 litres per minute,
the appliance must be capable of raising the
water temperature to a minimum of 52°C.
Water temperature at the inlet to the mixer
must remain relatively constant when flow
rate adjustments are made (refer to the water

heater operating manual to confirm compatibility
with this mixer shower).

: When installing this mixer

: Before installing with a gas

MUST be carried out by

This mixer shower is supplied with an integral
single check valve and integral large area filter
in each inlet. Inlet connections are by ½” BSP to
22mm or 15mm compression (not supplied).

SAFETY WARNINGS

a Layout and sizing of pipework MUST be

such that when other services are used,
pressures at the shower control inlets do not
fall below the recommended minimum.

b DO NOT choose a position where the

shower could become frozen.

c DO NOT connect this mixer shower

to any form of tap or fitting not
recommended by the manufacturer.

d The showerhead MUST be regularly cleaned

to remove scale and debris.

e Conveniently situated service valves in

each inlet supply MUST be fitted as an
independent method of isolating the
shower should maintenance or servicing be
necessary.

f 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 fitted. For advice on the Triton
scale inhibitor, please contact Customer
Service.

g DO NOT operate the shower outside

the guidelines as laid out in ‘site

requirements’.

Replacement parts can be ordered from Triton
Customer Service. See ‘spare parts’ for details and part
numbers.

Due to continuous improvement and updating,
specification may be altered without prior notice.

SITE REQUIREMENTS

The installation must be in accordance with
Water Regulations and Byelaws.

Running water pressure:

Gravity fed – 0.1 bar min.

1.0 bar max.
Mains fed – 1.0 bar min.

5.0 bar max.

Maximum static water pressure:

Gravity and mains – 10 bar

DO NOT connect the mixer shower to
a gravity hot supply and a mains cold
supply (or vice versa).

For the best performance within the specified
running pressure range a minimum flow of eight
litres per minute should be available to both
inlets.

While the mixer shower is operational (open
outlet), inlet pressures must not be capable of
exceeding 7 bar. For effective operation of the
internal seals, the maximum static pressure must
not be exceeded.

Note: On sites where the running pressure is
above 5 bar, the use of a suitably sized pressure
reducing valve fitted in the cold mains supply
pipework can provide nominally equal pressures
at the shower mixer.

The pipework should be installed such that the
flow is not significantly affected by other taps
and appliances being operated elsewhere on the
premises.

Note: Where thermal store systems and
instantaneous gas water heaters are used, if
excessive draw offs take place the boiler may
not be able to maintain an adequate output
temperature. This could result in the shower
temperature becoming noticeably cooler.

Water temperature requirements

Maximum hot water temperature = 80°C

Recommended maximum = 65°C

Minimum hot water temperature = 52°C

Maximum cold water temperature = 20°C

BS 6700 recommends that the temperature of
stored water should never exceed 65°C.

A stored water temperature of 60°C is
considered sufficient to meet all normal
requirements and will minimise the effects of
scale in hard water areas.

Temperature adjustment range

The mixed water temperature can be adjusted
from cold through to a top limit which must
be pre-set 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 flow to either incoming
supply then water from the shower will stop or
be reduced to a trickle until both supplies are
restored.

TYPICAL SUITABLE INSTALLATIONS

a) Instantaneous gas-heated systems,
e.g. combination boilers (fig.2)

The shower control MUST be installed with a
multipoint gas water heater or combination
boiler of a fully modulating design (i.e.
to maintain relatively stable hot water
temperatures).

A drop tight pressure reducing valve

MUST
be fitted if the supply pressures exceed 5 bar
running.

An expansion vessel (shown in

fig.2) MUST

be fitted, and regularly maintained, to ensure
the shower mixer is not damaged by excess
pressures. This may already be installed within
the boiler (check with manufacturer) and is in
addition to the normally larger central heating
expansion vessel.

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 hot supply temperature
MUST remain a minimum of 10°C hotter than
the required blend temperature for optimum
performance.

b) Unvented mains pressure systems
(fig.3)

The shower control can be installed with an
unvented, stored hot water cylinder.

For systems with no cold water take off after the
appliance reducing valve, it will be necessary to
fit an additional drop tight pressure reducing
valve when the mains pressure is over 5 bar.
The drop tight pressure reducing valve must be
set at the same value as the unvented package
pressure reducing valve.

Note: An additional expansion vessel (fig.3)
may be required if a second pressure reducing
valve is installed. This does not apply to
packages with a cold take off after the pressure
reducing valve to the cylinder.

The layout and sizing of pipework
such that nominally equal inlet supply pressures
are achieved and the effects of other draw-offs
are minimised.
