INTRODUCTION

This book contains all the necessary fitting and
operating instructions for your T40i booster
pump. Please read them carefully.

The installation must be carried out by a suitably
qualified person and in the sequence of this
instruction book.

Care taken during the installation will ensure a
long, trouble-free life from your booster pump.

The T40i booster pump is designed to improve
the flow rate through an existing bath/tap mixer
valve. It is NOT designed to pressurise the water
supply but only to assist the flow.

IT MUST ONLY be fitted to new or existing
gravity fed shower mixer systems.

The unit is easy to install requiring no plumbing,
only simple screw-on hose connections and a
suitable power supply.

Note: It must NOT be used with instantaneous
water heaters.

This product is suitable for installation in a
bathroom.

DO NOT install the unit so close to the bath
that the supplied hose becomes twisted or
kinked and restricts the water flow.

SITE REQUIREMENTS

Water

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

To ensure correct operation, the T40i unit
must be connected to a gravity fed system of
hot and cold water of equal pressure (fig.2).

The T40i pump MUST NOT be connected
to the mains water supply.

The unit must be positioned BELOW the cold
water cistern and NOT placed in areas where it
will be subject to freezing conditions.

Position the unit where it will NOT be in direct
contact with water from the sprayhead.

Both hot and cold water supplies to the
existing bath/tap mixer valve MUST be direct
and separate from any other outlets or
connections.

DO NOT use jointing compound on any pipe
fittings for installation.

Note: The outlet of the T40i pump acts as a
vent and must not be connected to any form
of tap or fitting that is NOT recommended by
the manufacturer.

Generally there are four main types of hot and
cold water mixer systems to which the T40i
can be installed. These are shown in (fig.2)
through to (fig.5).

In each case, to ensure correct operation of
the booster pump, the top of the T40i unit
MUST be at least 230mm below the bottom of
the cold water cistern and the sprayhead must
be a minimum of 100mm below the water
level of the cold water cistern.

Note: Bath mixer valves incorporating a
diverter valve can have a high restriction to
water flow, so the expected improvement may
not be possible.

Water circuits supplying the T40i unit should
be installed so that the flow is not significantly
affected by other taps and appliances that are
being operated elsewhere on the premises.

THIS INSTALLATION MUST BE EARTHED.

This product must be permanently connected to
the electricity supply, via a double pole switch
with at least 3mm contact separation. This can
be a ceiling mounted pull cord switch, or a wall
mounted switch, both of which must be fused
at 3A. The switch must be readily accessible and
clearly identifiable, but out of reach of a person
using a fixed bath or shower, except for the
cord of a cord operated switch.

The installation and wiring must comply with
the current IEE regulations.

The supply cable and circuit protection must
conform with IEE wiring regulations and be
sufficient for the amperage required. In most
cases 1mm² twin and earth cable will be
adequate.

If in any doubt consult a qualified electrician or
contact Triton Customer Service for advice.

in the hose and mark the position of the fixing
holes (fig.8). Remove the flexible hose from the
T40i and mixer valve.

Drill and plug to suit the fixing screws supplied.

(The wallplugs 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 special wallplugs and an suitable drill
bit).

Screw the top fixing screw into position leaving
the base of the screw head protruding 6mm out
from the wall.

Hook the backplate over the top screw and fit
the bottom fixing screw into position.

The bottom fixing hole is elongated to allow for
out of square adjustment. Tighten both screws
when correctly positioned.

ELECTRICAL CONNECTIONS

Note: A double pole linked switch with a
minimum contact gap of 3mm in both poles
must be fitted in the circuit.

IMPORTANT: The T40i unit must be supplied
by fixed wiring. The supply cable must
conform to relevant tables in current IEE
regulations. The electrical rating of the T40i
is shown on the rating label within the unit.

Fig.10 shows a schematic wiring diagram.

SWITCH OFF THE ELECTRICITY SUPPLY AT THE
MAINS.

The cable entry points are shown in fig.1. The
cable can be surface clipped, hidden or via
20mm conduit.

Note: Conduit entry can only be from the rear.
Route the cable into the unit and connect to the
terminal block (fig.11) as follows:

Earth cable to terminal marked E

Neutral cable to terminal marked N

Live cable to terminal marked L

IMPORTANT: Fully tighten the terminal block
screws and make sure that no cable
insulation is trapped under the screws.

Note: The supply cable earth conductor must
be sleeved. The cable clamp (fig.10) is suitable
for up to 4mm² cable, but in most cases 1mm²
cable will be enough.

The earth continuity conductor of the electrical
installation must be effectively connected
electrically to all exposed metal parts of other
appliances and services in the room in which the
T40i is to be installed, to conform to current IEE
regulations.

The use of connections within the unit to supply
power to other equipment i.e. extractor fans,
pumps etc. will invalidate the guarantee.

DO NOT switch on the electricity supply
until the cover has been fitted.

WARNING!

This appliance must be earthed.

'Dogs'

REPLACING THE COVER AND TESTING

Procedure

a) Make sure the switch spindle adaptor ‘dogs’

are positioned as shown (fig.12).

b) Position the control knob on the cover to

‘stop’ (fig.15).

c) Offer the cover to the unit and plug the

loose neon into the bracket that is located
inside the cover (fig.13).

Place the cover squarely over the backplate and
guide into position so that the extended ‘dogs’
of the spindle adaptor slot into the recess of the
control knob. Should any difficulty arise, recheck
the points above.

Secure the cover in position with the two
retaining screws. DO NOT OVERTIGHTEN.

Turn on the water supply at the mixer valve/tap
and adjust to a normal showering temperature.

Make sure the control knob is at the ‘stop’
position. Switch on the electricity supply at the
isolating switch.

Turn the control knob to the ‘start’ position
(fig.14). The pump will start and the neon will
illuminate. Check for an increase in water flow.
Turn the control knob to the ‘stop’ position
(fig.15). The water flow should decrease. Turn
off the water at the mixer valve/tap.

The installation should be checked for any leaks
from the hose connections.

OPERATING

Ensure the electric isolating switch is on to the
T40i. Turn on the water supply at the mixer
valve/tap and adjust to a showering
temperature.

Switch the T40i control knob to ‘start’ (fig.14).
The pump will start and the neon will illuminate.

Adjust shower temperature as normal.

Note: With the push-on hose systems the T40i
pump should not be switched on until water
flows from the sprayhead.

When showering is completed, switch the T40i
control knob to ‘stop’ (fig.15).

Turn off the mixer valve or taps.

MAINTENANCE

It is recommended that the booster pump unit
and hoses be cleaned using a soft cloth and that
the use of abrasive or solvent cleaning fluids be
avoided.

Before cleaning, turn off the unit at the isolation
switch to avoid accidental switching on of the
booster pump.

IT IS MOST IMPORTANT TO KEEP THE EXISTING
SPRAYHEAD CLEAN IN ORDER TO MAINTAIN
THE PERFORMANCE OF THE SHOWER.

The hardness of water will determine the
frequency of cleaning. For example, if the
shower is used every day in a very hard water
area, it may be necessary to clean the sprayhead
on a weekly basis.

If the T40i pump is not used for lengthy periods,
it is recommended to turn on the water at the
mixer valve/tap then switch the pump on for
two or three minutes periodically to prevent the
motor shaft seals from seizing.

Do not run the T40i pump dry.

WARNING!

Do not use ‘powerful’ abrasive or solvent

cleaning fluids when cleaning the booster
pump as they may damage the plastic
fittings.
