Please read this book thoroughly and familiarise yourself with all instructions
before commencing installation.
Please keep it for future reference.
The shower installation MUST be carried out by a suitably qualified person, in the
sequence of this fitting instruction.
ADVICE TO USERS
The following points will help you understand how the shower operates:
a) The electric heating elements operate at a constant rate. It is the rate of water
passing over the heater elements which determines the water temperature. The
slower the water flow, the hotter the water becomes; the faster the water flow, the
cooler the water.
b) During winter, the mains water supply will be cooler than in the summer. The
water flow rate will therefore vary between seasons, the thermostatic control of
the Tri-HUB will automatically maintain the desired temperature.
c) The temperature controls can be adjusted to provide shower temperatures
between 32°C and 46°C (or ambient if cold mode is activated). At any selected
showering temperature the unit will automatically provide the optimum flow rate
possible.

INSTALLATION REQUIREMENTS
Please read IMPORTANT SAFETY INFORMATION and SPECIFICATION sections before
undertaking the plumbing installation.
NOTE: If the recommended dynamic pressure and flow is not available, there could be a
noticeable reduction in performance from the shower head.
If it is intended to operate the shower at pressures above the maximum or below the
minimum stated, contact Customer Experience for advice.
1. The Tri-HUB MUST NOT be positioned where it will be subjected to freezing conditions.
Any pipework MUST BE insulated to avoid being frozen.
2. The installation must be in accordance with Water Regulations/Bylaws.
3. DO NOT use jointing compounds on any pipe fittings for the installation.
4. DO NOT solder fittings near the shower unit as heat can travel along pipework and damage
components.
5. Compression or demountable push-fit fittings can be used to connect to the shower Inlet
and Outlet connectors.
6. NOTE: DO NOT use non-demountable push-fit fittings on the Inlet and Outlet as this will
prevent servicing and may invalidate the warranty of the product.
7. Important: An additional full bore stop valve (complying with Water Regulations) must be
fitted in the mains water supply to the shower as an independent means of isolating the
water to carry out maintenance or servicing. If this isolator and/or Tri-HUB is fitted in a loft
space, the loft must have a fixed access ladder and be boarded, with appropriate lighting
from the access point to the isolator.
8. Important: Before completing the connection of the water supply to the inlet of the shower,
ush out the pipework to remove all swarf and system debris.
9. Important: The Tri-HUB must be mounted on a even vertical surface otherwise the Tri-
HUB’s inbuilt sensors will not allow for the ENVi®shower to operate.
10. Position of the shower: Refer to Fig.1 for correct location of the Tri-HUB. Always mount
the Tri-HUB vertically and allow enough room for the installation of elbows or straight
connectors onto the Inlet and Outlet stems at the base of the Tri HUB.
IMPORTANT Water Regulations: It is required that the shower head be ‘constrained by a
fixed or sliding attachment so that it can only discharge water at a point not less than 25mm
above the spill-over level of the relevant bath, shower tray or other fixed appliance’.
If the riser kit is supplied with a ‘soap dish hose retainer’ or bespoke ‘hose retainer’, it will in
most cases meet this requirement. If the shower head can still be placed within a bath, basin
or shower tray within the 25mm limit, then a double check valve, or similar, MUST be fitted in
the supply pipework to prevent back-flow.

INSTALLATION REQUIREMENTS
Please read IMPORTANT SAFETY INFORMATION and SPECIFICATION sections before
undertaking the electrical installation.
The installation, supply cable and circuit protection must conform with BS 7671 (IEE wiring
regulations) and be sufficient for the amperage required.
The following notes are for guidance only:
1. The Tri-HUB must only be connected to a 230-240V AC supply. Any drops in voltage due to
localised heavy demand may reduce the shower’s performance
2. The electrical rating of the Tri-HUB is shown on the rating label (Fig.3) which is positioned on
the front of the Tri-HUB cover.
3. Before making any sort of electrical connection within the installation make sure that no
terminal is live. If in any doubt, switch o the whole installation at the mains supply and
remove the correct fuse.
4. The Tri-HUB must be connected to its own independent electrical circuit. IT MUST NOT be
connected to a ring main, spur socket outlet, lighting circuit or cooker circuit.
5. The electrical supply must be adequate for the loading of the unit and existing circuits.
6. Check your consumer unit (main fuse box) has a main switch rating of 80Amps or above
and that it has a spare fuse way which will take the fuse or Miniature Circuit Breaker (MCB)
necessary for the shower rating.
7. If your consumer unit has a rating below 80A or if there is no spare fuse way, then the instal-
lation will not be straightforward and may require a new consumer unit serving the house or
just the shower. Contact a professional electrician/local electricity company for advisement.
8. For close circuit protection DO NOT use a rewireable fuse. Instead use a suitably rated
Miniature Circuit Breaker (MCB) or cartridge fuse. Triton recommend the following circuit
protection: 9.0KW variant - 40Amp 10.5kW variant - 45Amp
9. A 30mA residual current device (RCD) MUST be installed in all UK electric shower circuits. This
may be part of the consumer unit or a separate unit. A suitably rated RCBO could be used if
the RCD is not present and the consumer is compatible with the RCBO.

INSTALLATION REQUIREMENTS
10. A 45 amp double pole isolating switch with a minimum contact gap of 3mm in both poles
must be incorporated in the circuit. It must have a mechanical indicator showing when the
switch is in the OFF position, and the wiring must be connected to the switch without the
use of a plug or socket outlet.
11. The switch must be accessible and clearly identiable, but out of reach of a person using
a xed bath or shower tray/cubicle, except for the cord of a cord operated switch, and
should be placed so that it is not possible to touch the switch body while standing in a
bath or shower tray/cubicle. It should be readily accessible to switch o after use.
12. Where shower cubicles are located in any rooms other than bathrooms, all socket outlets
in those rooms must be protected by a 30mA RCD.
13. The current carrying capacity of the cable must be at least that of the shower circuit
protection (Fig.2). To obtain full advantage of the power provided by the shower, use the
shortest cable route possible from the consumer unit to the Tri-HUB.
14. The electrical circuit to the Tri-HUB should be separated from other circuits by at least
twice the diameter of the cable or conduit. The current rating will be reduced if the
cabling is bunched with others, surrounded by thermal loft or wall insulation or placed
in areas where the ambient temperature is above 30°C. Under these conditions, derating
factors apply and it will be necessary to select a larger cable size (Fig.2). In the majority of
installations, the cable will unavoidably be placed in one or more of the above conditions.
This being so, it is strongly recommended to use a minimum of 10mm² cabling throughout
the shower installation. In any event, it is essential that individual site conditions are
assessed by a competent electrician in order to determine the correct cable size and
permissible circuit length.

INSTALLING IN THE LOFT
If the Tri-HUB is being installed in a loft area, then the
following requirements must be met for future servicing
purposes:
- There must be no risk of the Tri-HUB, inlet water supply
pipe or outlet heated water pipe becoming frozen.
- The Tri-HUB must not be covered with any form of
insulating material that may give rise to electrical
circuits overheating during periods of high ambient
temperature.
- A safe means of access must be provided into the loft,
e.g. via a xed loft ladder.
- The Tri-HUB must be installed in an accessible and safe
location.
- Ceiling joists must be adequately boarded to provide safe and unobstructed access to,
from, and around the Tri-HUB.
- There must be adequate lighting in the loft for servicing purposes.

POSITIONING THE Tri-HUB
The Tri-HUB may be installed in a loft space, in a convenient cupboard space, or the bathroom
environment, provided there is access and enough room for maintenance and the ambient
temperature is within the stated parameters listed on Pg.6. Always position the Tri-HUB in a dry
area, but it must be well ventilated and not covered with towels, sheets, etc.
Ensure the Tri-HUB is installed in a position that will minimise the length of pipe runs to the
shower head/accessory ttings. Triton recommend that the length of pipe should NOT exceed 3
metres, as the length of pipework will inuence any losses in water temperature and response
time when showering temperature settings on the ENVi® Controller are changed.
To avoid any signicant ow losses, the pipework should be designed and installed such that
bends or the use of elbows are minimised. The Tri-HUB should also be positioned so the ow
is not signicantly aected by other taps and appliances being operated elsewhere on the
premises.
All pipework MUST be rigidly supported to avoid any strain on the connections and vibrations
during use.
The Tri-HUB must always be mounted vertically on a even surface which covers the full width
and length of the backplate. DO NOT MOUNT IT HORIZONTALLY as inbuilt sensors will not
allow for the ENVi® shower to operate.
Allow enough room at the base of Tri-HUB to allow for plumbing xings to be connected to the
Inlet and Outlet stems.
The Tri-HUB must always be positioned so that there is easy access for servicing and
maintenance.
If a suitable wall is not available for mounting, then a support structure similar to that in Fig.5
should be manufactured and used.

ENVi®CONTROLLER INSTALLATION
The ENVi®Controller is connected to the Tri-HUB via the 10 metre data cable supplied, the
distance between the Tri-HUB and Controller MUST be within this distance (including any
allowance for the routing of the cable).
IMPORTANT: The ENVi® Controller has been designed to allow for installation within a
bathroom environment. However, consideration should be given to the location, as water
splashing onto the controller glass could trigger false activation during use.
IMPORTANT: The controller must be located whereby the user can start and stop the shower
immediately.
DATA CABLE INSTALLATION
IMPORTANT: UNDER NO CIRCUMSTANCES SHOULD THE DATA CABLE BE EXTENDED OR
SHORTENED, AS NOT ONLY WILL IT IMPAIR THE PERFORMANCE OF THE SHOWER, BUT IT
WILL ALSO INVALIDATE THE GUARANTEE.
The data cable is not supplied factory tted and will need to be attached to the Tri-HUB and
ENVi® controller during installation.
The installer MUST ensure appropriate care is taken to ensure the orientation features on
the connector are correctly aligned during cable attachment (step 3). Damage to the pins will
cause data connection issues and may render the unit inoperable.
A 30mm diameter hole needs to be made within the showering area to allow for the data
cable connection.
Run the data cable from the Tri-HUB into the showering area. Make sure there is enough
slack cable at the controller end for the removal of the Controller for future maintenance.
Approximately 150mm protruding length should be sucient.
If the data cable is being routed through wall cavities, chased into solid walls, or surface
mounted, then appropriate trunking/conduit MUST be used. Data cables MUST be tted in
such a way so that they can later be removed for maintenance or servicing.

Apply a small bead of silicone sealant around the
Ø30mm hole, to seal the bracket to the wall.
Secure the xing bracket to the wall using the
appropriate xings.
Whilst securing the xing bracket to the wall,
the data cable must be pulled through so that
approximately 150mm protrudes from the wall, this
will help make the connection to the
controller easier.

Ensure the electricity and water supplies to Tri-HUB are ON, and the Data Cable is
connected to both the ENVi® Controller and Tri-HUB as described in the installation sections
of this book. When the Start/Stop icon is illuminated, touch it to wake the shower. The
TRITON logo will appear briey, this will then be replaced with the instructions to start the
commissioning process.
IMPORTANT: It is recommended that during the commissioning procedure the
outlet connections and plumbing are checked for any water leakage.
You may need help from an additional person to assist in this process.
Resolve any leaks or plumbing issues, and after fixing, repeat the commissioning
process to be confident that the pipework and water connections do not have any
water leakage.
