Our vision is to design and craft aspirational yet
practical water conservation solutions that eliminate
shower water wastage without compromising the
shower experience.
We understand that enjoying a quality shower is an
important part of our daily routine. This experience
should not be marred by ineffective attempts to save
water, or feelings of guilt with your hand under the
shower while watching litres of water being wasted
down the drain until the hot water arrives.
The Triton Xerophyte has been designed to
incorporate innovative water conservation features,
while at the same time delivering outstanding
performance for the best possible shower
experience.

Installers please note these instructions are to be left with the user

This book contains all the necessary installation instructions for your Triton Xerophyte
Smart Water-Saving Shower Mixer –please read them carefully. Care taken during the
installation will provide a long, trouble-free life from your shower.
All installations must comply with SANS 10252-1 and SANS 10254 requirements.
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.
Standards and approvals
The Triton Xerophyte Control Unit is an independently mounted electronic Control Unit.
The Unit complies with the requirements of current British, European and South African
safety standards for household and similar electrical appliances and meets the Compliance
with European New Approach Directives (CE) and South African National Regulator for
Compulsory Specifications (NRCS).
Declaration of conformity
Triton Showers declares that the Triton Xerophyte products, in conjunction with Controls,
comply with the essential requirements and other relevant provisions of the Low Voltage
Directive (2014/35/EU) and the EMC Directive (2014/30/EU) and the RE Directive (2014/53/
EU).
Please read this guide thoroughly and familiarise yourself with all instructions before
commencing installation. It should be retained for future reference.
The shower installation MUST be carried out by a suitably qualified person, following the
sequence of this instruction guide.
Plumbing
Supply pipes must be flushed to clear debris before connecting the Triton Xerophyte Mixer
Unit.
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.
DO NOT use excessive force when making connections to the Triton Xerophyte Mixer Unit
shower inlets.
DO NOT choose a position where the Triton Xerophyte Mixer Unit will become frozen or
overheat in hot summers (> 40 °C).
DO NOT connect the Triton Xerophyte Mixer Unit to any form of tap or fitting not
recommended by the manufacturer.

The showerhead or other approved Triton devices MUST be regularly cleaned to remove
scale and debris, especially if operated in areas with hard water (above 200 ppm temporary
hardness).
DO NOT operate the Triton Xerophyte Mixer Unit outside the guidelines as laid out in ‘site
requirements’ and ‘specifications’.
When installed in a gravity-fed system the top of the Triton Xerophyte Mixer Unit MUST be
at least 100 mm lower than the base of the cold water cistern to prevent the unit from
running dry. A dedicated cold water supply MUST be taken directly from the cold water
cistern to the Triton Xerophyte Mixer Unit, to ensure there is sufficient water pressure for
the unit to operate as intended. This draw-off MUST be on the opposite side of the cistern
to the float operated valve to reduce the risk of air entering the unit. The infill to the cistern
should be checked to ensure an adequate infill rate of 16liter/minute occurs.
Electrical
The installation must comply with The South African National Standards and the Electrical
Contractor regulations SANS 10142-1 (Edition 2). Make sure metal incoming hot and cold
water supplies to the Triton Xerophyte Mixer Unit are adequately earth bonded.
DO NOT turn on the electrical supply until the plumbing connections have been
completed. Only then can the electricity be switched to undertake commissioning. The
Triton Xerophyte Mixer Unit must not be operated dry (without water).
The Triton Xerophyte Mixer Unit MUST be connected to a means for disconnection from
the main electrical circuit. The Triton Xerophyte must be connected to a residual current
device circuit breaker in accordance with current wiring regulations.
If the Triton Xerophyte Mixer Unit is to be installed within a bath or shower room the
electrical installation MUST conform to SANS 10142-1: 2017 (Edition 2).
The Triton Xerophyte Mixer Unit MUST only be used with the AC power supply cable
provided. If this supply cable is damaged, it must be replaced by a qualified person to avoid
a hazard.
Uninterrupted power supply (UPS)
In areas with frequent power outages, we strongly recommend that you connect the Triton
Xerophyte Mixer unit to a minimum 850VA inline interactive uninterruptible power supply
(UPS).
Solar panels with battery backup
Should there be an inverter powered by battery backup, connect the Triton Xerophyte to a
plug point on the backup power line to ensure uninterrupted use during power outages.

Professional Installer Notes
On premises with metallic surfaces e.g. metal ceiling panels,
metal ducting and metallic insulating materials, we recommend
wired connection as wireless transmissions MAY BE BLOCKED
from the control panel and thus prevent correct operation of
the shower.

Installation Information
10
The installation MUST BE carried out in accordance with these instructions,
and MUST BE undertaken by a qualified competent person.
The Triton Xerophyte Mixer Unit may be installed in a loft space, in a convenient cupboard or in
the shower with the Xerophyte Vanity cove (sold separately), provided there is enough room for
maintenance. Safe and easy access to the Triton Xerophyte Mixer Unit should be available at all
times.
When planning the installation, if you are using the wired connectivity ensure that the distance
between the Triton Xerophyte Mixer Unit and Triton Xerophyte Control Unit is within the
recommended range of the 10-metre data cable supplied, ensuring that the data cable routing
is taken into consideration.
Ensure that the Triton Xerophyte Mixer Unit is installed in a position that will minimise the
length of pipe running between the Triton Xerophyte Mixer Unit outlet and the
showerhead/accessory fittings. The length of pipework from the Triton Xerophyte Mixer Unit to
the outlet fitting MUST NOT exceed 5m.
The length of pipework running from the Triton Xerophyte Mixer Unit to the
showerhead/accessory fittings will affect the showering temperature and the response time
when changing the showering temperature on the Triton Xerophyte Control Unit. The shorter
the length of pipework the better the Triton Xerophyte Mixer Unit functioning, improving its
water-saving efficiency and enhancing the shower experience
When installing the Triton Xerophyte Mixer Unit in an area not regularly accessed, consideration
for potential leaks MUST be taken into account. While such events are unlikely, it is advisable to
periodically check the installation for traces of water on or around the Triton Xerophyte Mixer
Unit. If possible install or position the Triton Xerophyte Mixer Unit in a location where any leak
would be contained or routed to avoid areas sensitive to water damage.
Isolation valves are integrated into the push-fit connection fittings supplied for the hot & cold
inlets, ensure that after installation these valves are left in the fully open position as failure to do
this will result in poor flow and circulation performance and extended warmup time from the
Triton Xerophyte Shower Mixer.
The Mixer Unit MUST NOT be positioned where it will be subjected to freezing or overheating
conditions ( > 40 °C ). Water-saving efficiency might be influenced if installation is in an area
where cold water temperature exceeds 29 degrees. In such installation, the circulation
threshold can be adjusted to 32 degrees in the “Circulation Temperature Threshold” settings.
All pipework MUST be rigidly supported to avoid any strain on the connections and vibrations
during use. Long inlet pipework (dead-legs) should be kept to a minimum to avoid showering
temperature fluctuations. The pipework should be installed such that the flow is not
significantly affected by other taps and appliances being operated elsewhere on the premises.
DO NOT connect the Triton Xerophyte Mixer Unit to a gravity hot supply and a mains cold
supply (or vice versa).
There are no user-serviceable components beneath the cover of the Triton Xerophyte Mixer
Unit.

Important if using Wireless connected devices
Triton recommends wired installation whenever the installation permits, however, if
wireless installation is necessary adhere to the installation guidelines below.
Metal objects such as steel baths, cold water storage tanks, hot water cylinders, radiators,
foil-lined plasterboard, and even thick brick walls can all dramatically reduce the wireless
operational range.
Interference from other wirelessly controlled devices and radio signals can dramatically
reduce the ability of the wireless Triton Xerophyte Shower Mixer to maintain a good,
consistent wireless signal. This may include mobile phones, cordless phones, radio-
controlled toys, wireless doorbells, etc.
If you encounter difficulty whilst setting up the wireless connectivity of the Triton Xerophyte
Shower Mixer, ensure all other radio interference is temporarily switched off.
Failure to follow these wireless connectivity guidelines can result in poor, intermittent, or
failure of communication between the Triton Xerophyte Control Unit and the Triton
Xerophyte Mixer Unit.
Typical Suitable
Installations
11

High-Pressure Instantaneous Hot Water System Installation
The Triton Xerophyte Mixer Unit MUST
be installed with a multipoint on demand
gas water heater of a fully modulating
design (i.e. where the water draw-off rate
indirectly controls the gas flow rate to the
burner).
A drop tight pressure reducing
valve MUST be fitted if the supply
pressures exceed 500kPa (5 bar) running.
It is recommended that an expansion vessel
is fitted (and regularly maintained) if any form,
of backflow prevention device is fitted i.e. PRV.
This will ensure that excess expansion or
pressure pulses do not damage the product.
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.
A non-return valve MUST be fitted
before the Expansion Valve (Fig 1).

To fit the flow regulator
1. Unscrew the hot inlet nut and remove the inlet pipe, O ring seal, inlet filter, and flow
regulator housing.
2. Fit the flow regulator into the flow regulator housing.
3. Refit the flow regulator housing, Inlet filter, O ring seal, and inlet pipe, secure with the hot
inlet nut. Note: the hot inlet nut only requires to be hand tightened.
When the Warm-Up function is finished with an instantaneous water heater appliance the
user may experience a brief temperature variation upon restart. This is due to how a
combination boiler operates, such that the boiler will turn off after the warm-up process has
been completed. When restarted, the processing unit will release a cold slug of water
followed by a hot slug as the hot water supply stabilises.

High-Pressure Instantaneous Hot Water System Installation Continued
On-demand gas heaters are not always able to supply an adequate flow rate of hot
water, particularly in winter. Triton recommends fitting a flow regulator (supplied
with the shower) into the Hot inlet of the Triton Xerophyte Mixer Unit before
installation. Refer to the table for details (see Fig 2).

High-Pressure Unvented Mains
Pressure Cylinder Installation
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 500kPa (5 bar).
The drop tight pressure reducing valve
MUST be set at the same value as the
unvented package pressure reducing
valve.
A non-return valve MUST be fitted
before the stop tap (Fig 3).
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 MUST
be such that nominally equal inlet
supply pressures are achieved and the
effects of other draw-offs are minimised.

High-Pressure Thermal Store
Systems Installation
The high-pressure system MUST be fitted
with a tempering valve (blender valve).
The appliance MUST be capable of raising
the temperature of the incoming water to
a minimum of 55°C and delivering a flow
rate of not less than 8 L/minute.
A drop tight pressure reducing valve
MUST be fitted if the supply pressures
exceed 500kPa (5 bar) running.
IMPORTANT
A non-return valve MUST be fitted before
the expansion valve (Fig 4)
It is recommended that an expansion
vessel is fitted (and regularly maintained)
(shown in Fig 4), to ensure the unit is not
damaged by excess pressures. This may
already be installed externally or internally
within the thermal store (check with the
thermal store manufacturer). It is
recommended that an expansion vessel is
fitted (and regularly maintained) if any
form.

Low-Pressure Gravity Fed
Systems Installation
IMPORTANT: The minimum head for the
operation of the Triton Xerophyte Mixer
Unit is 100 mm. For optimal operation, the
Xerophyte Mixer Unit MUST be put as
close as possible to the hot water cylinder.
Shortening the distance between the
Xerophyte Mixer Unit and the hot water
supply will shorten the warm-up period.
The Triton Xerophyte Mixer Unit MUST
be fed from a cold water cistern and hot
water cylinder providing nominally equal
pressures.
For the operation of the shower only,
it is recommended that the cold water
storage cistern is capable of holding at
least 114 litres (25 gallons). Where other
hot and cold outlets are likely to be in use
simultaneously, the storage capacity
should be increased to 228 litres
(50 gallons).
IMPORTANT: Pipework layouts and connections MUST be such that other draw-offs will not
affect water supplies to the Triton Xerophyte Mixer Unit, shared supplies may lead to air
locking or water starvation. It is, therefore, essential to have independent hot and cold
supplies to the Triton Xerophyte Mixer Unit.
If the hot water draw-off is incorrectly positioned, air may be drawn into the hot supply from
the vent pipe causing spluttering, and temperature fluctuations at the showerhead.
Any draw-off for the Triton Xerophyte Mixer Unit MUST point DOWN (to avoid air-lock
problems) and MUST be BELOW the vent pipe tee.
Failure to correctly position the draw-off will result in poor performance or other problems
with the Triton Xerophyte Mixer Unit.
Note: If the hot water source is moved or replaced at a later stage, a factory reset is required.

General installation Guidelines
The Triton Xerophyte Mixer Unit MUST only be
positioned as shown.
The Triton Xerophyte Mixer Unit can be
mounted on a horizontal surface in any
orientation(Fig 6).
When mounting on a vertical surface the
processing unit outlet MUST be at the bottom
(Fig 7). Failure to position the unit correctly
could result in a significant reduction in
performance.
IMPORTANT
If wall-mounting the Triton Xerophyte Mixer
Unit the outlet MUST always be at the
BOTTOM (Fig 7).
Decide on the position for the Triton
Xerophyte Mixer Unit. Position the Triton
Xerophyte Mixer Unit in a dry, well-ventilated
area.
The Triton Xerophyte Mixer Unit MUST always
be positioned either flat on a suitable surface
or on a wall so that there is easy access for
installation and maintenance.
Mark the four locating screw points for the
base. If fixing to a brick wall or a stud partition,
drill and plug the wall. (The wall plugs
provided are suitable for most brick walls —
use an appropriate masonry drill, but if the wall
is plasterboard or a soft building block, you
MUST use suitable wall plugs and an
appropriate drill bit). Secure the Triton
Xerophyte Mixer Unit in position using the 4
screws supplied (Fig 8).

If the Triton Xerophyte Mixer Unit is installed in a loft area the following
requirements MUST be met for future servicing purposes:
a. There MUST be no risk of the Triton Xerophyte Mixer Unit or water pipe becoming frozen or
overheating ( > 40 °C) in hot summers.
b. The Triton Xerophyte Mixer Unit MUST NOT be covered with any form of insulating
material.
c. A safe means of access MUST be provided into the loft, e.g. via a fixed loft ladder.
d. It is recommended that the Triton Xerophyte Mixer Unit be installed in an accessible and
safe location.
e. Ceiling joists MUST be adequately boarded to provide safe and unobstructed access to,
from, and around the Triton Xerophyte Mixer Unit.
f. There MUST be adequate lighting in the loft for servicing purposes.
Note: If mounting the Triton Xerophyte Mixer Unit in a loft it is worth considering building a
catchment tank with an overflow pipe directed to an external point. In the unlikely event of a
problem occurring with the Triton Xerophyte Mixer Unit, this will give a visual indication of
any failure.
Plumbing connections
Plumbing/Pipe installation to
be carried out before electrical
wiring installation.
DO NOT use jointing
compounds on any pipe fitting
for the installation.
DO NOT solder fittings near
the shower unit as heat can
transfer along with pipework
and damage components.

IMPORTANT:
The fittings on the inlets, outlets and circulation loop are the push-fit type. The pipework
MUST be cut with a pipe cutter and all burrs and rough edges removed from the end of the
tube. The fittings can be used with copper and plastic pipe.
If using a chrome-plated copper pipe, remove the first 25 mm of plating completely from the
connecting surfaces. If not completely removed then the collet will not grip the pipe and
under pressure, the pipe may be forced out.
Before completing the connection of the water supplies to the inlets of the Triton Xerophyte
Mixer Unit, flush out the pipework to remove all swarf and system debris.
1. Turn off the water supplies either at the mains stop valve or the isolating stop valve.
2. Having decided on the position of the unit and direction of pipe entry, complete the
pipework to the Triton Xerophyte Mixer Unit.
3. Check for leaks before connecting the pipework to the Triton Xerophyte Mixer Unit.
4. Insert the incoming pipework into the 15 mm push-fit connectors (Fig 10).
5. Check that the isolating valves on the inlet connectors are fully open (Fig 11).
All pipework should be insulated. DO NOT attempt to insulate or cover the Triton Xerophyte
Mixer Unit.
