1 PLUMBING NOTES
1.1 All installations must comply with Water
Regulations/Byelaws.
1.2 Supply pipes must be flushed thoroughly
to clear debris before connecting to the
pump and shower.
1.3 DO NOT connect the pump unit to the
mains cold water supply as it would
damage the unit and also, the installation
would be in breach of the guidance notes
contained in ‘1’ above.
1.4 DO NOT use excessive force when making
connections to the flexible connector hoses.
1.5 DO NOT turn on the electrical supply to
the pump until the plumbing connections
and commissioning procedure have been
completed. The pump must not be
operated dry without water.
1.6 DO NOT solder pipes or fittings within
300mm of the pump, as heat transfer can
damage the components.
1.7 A dedicated cold water supply must be
taken directly from the cold water cistern
to the pump. This draw-off must be on
the opposite side of the cistern to the float
operated valve.
1.8 The action of the pump is to increase the
flow rate. If the supply pipework cannot
handle the resulting flow rate then:
1.8.1 The anticipated flow rate may not
be achieved.
1.8.2 Air may be drawn into the hot
supply from the vent pipe causing
spluttering and temperature fluctuations at
the sprayhead.
1.9 A high level hot feed pipe run must not rise
above the level of water in the cistern. To
reduce the risk of air locks pipes should be run
level with or below the base of the cistern.
1.10 Standard gate valves or full way lever
valves MUST be fitted on the hot and
cold water supplies to the pump as an
independent means of isolating the water
supplies should maintenance or servicing
be necessary.
DO NOT use stop taps or ball-o-fix type
valves which restrict flow.
1.11 If the pump unit is installed on a common
supply which feeds an adjacent tap, the
maximum static inlet pressure for the
unit will, under certain circumstances be
exceeded. The action of closing the tap
can cause a pulse in the supply pressure
which may result in damage to the unit.
This can be resolved by the installation
of a suitably sized mini expansion vessel,
sited as close as possible to the tap and
pressurised to 50kPa (0.5 bar).
2ELECTRICAL NOTES
2.1 The installation must comply with BS 7671
‘Requirements for electrical installations’
(IEE wiring regulations). Ensure the
incoming hot and cold water supplies to
the pump are adequately earth bonded.
2.2 DO NOT turn on the electrical supply to
the pump until the plumbing connections
have been completed. The pump must
not be operated dry without water.
2.3 The mains supply must be 230-240V, at
50Hz, connected to the pump via a double
pole switched 3 Amp fused connection
unit (not supplied) with a minimum 3mm
contact separation gap in each pole.
2.4 In accordance with ‘The Plugs and Sockets
etc. (Safety) Regulations 1994’, the pump
is intended to be permanently connected
to the fixed electrical wiring of the mains
system.
2.5 To enhance electrical safety a 30mA
residual current device (RCD) should be
installed in all UK electric and pumped
shower circuits. This may be part of the
consumer unit or a separate unit.
Replacement parts can be ordered from Triton
Customer Service. See ‘spare parts’ for details.

WATER REQUIREMENTS
The installation must be in accordance with
Water Regulations and Byelaws.
For correct operation of this shower pump in
addition to the shower unit, water must be
gravity fed at nominally equal pressures directly
from the same cold water storage cistern (the
hot water being fed to the pump via the hot
water cylinder).
The cold water cistern and hot water cylinder
must each have a minimum capacity of 114
litres (25 galls). It is advisable to check that the
infill rate from the float operated valve meets
the output requirements. If the cistern supplies
water to a number of cold outlets it is advisable
to increase the stored water capacity to 230
litres (50 galls).
Both hot and cold water supplies to the pump
must be direct and not significantly affected by
any other outlets or connections.
(Fig.2) shows a recommended installation
where the hot water supply for the shower is
made via a tee connection on the underside of
the rising horizontal section of pipework from
the cylinder. Alternatively, the connection can be
taken from the hot supply pipe to other outlets
as long as it is the first draw-off below the
ventilation pipe tee.
THE PUMP MUST NOT BE CONNECTED TO THE
MAINS COLD WATER SUPPLY.
DO NOT connect into the rising vent pipework.
The pump must be positioned below the cold
water cistern and not placed in areas where it
will be subject to freezing conditions.
To ensure correct operation of the flow switches,
all pipework must be below the cold water cistern
and the sprayhead must be at least 150mm
below the bottom of the cold water cistern.
In situations where this requirement cannot be
met, contact Triton Customer Service for advice.
If used with a combination cylinder, the cold
water cistern must have a capacity of at least
114 litres (25 galls) to avoid starvation of water
to the pump, and a minimum head of water of
150 mm.
DO NOT use jointing compounds on any pipe
fittings.

ELECTRICAL REQUIREMENTS
The pump must be connected to a 230 – 240V
A.C. electrical supply, via a double pole switch
with at least 3mm contact separation. This can
be a ceiling mounted pull cord switch in the
shower room, or a wall mounted switch in an
adjacent room.
The pump installation should be fused at 3
amps.
It is recommended that a suitable residual
current device (RCD) is fitted in the electricity
supply circuit to this appliance.
Note: The installation and wiring must comply
with current IEE regulations.
When installed in any room containing a fixed
bath or shower, the pump MUST be located and
concealed inside a suitable cupboard, built-in
unit or other enclosure, in order so the pump
cannot be sprayed with water, and such that
a person using a fixed bath or shower cannot
touch the pump without using tools.
WARNING!
THE PUMP MUST BE EARTHED.
SITING OF THE PUMP
The pump MUST ALWAYS be positioned
BELOW the cold water cistern and be situated
as close as possible to the hot water cylinder.
It is recommended that the cold water supply
is taken from the opposite side of the cistern
to the float operated valve to prevent air
entrapment in the supply.
Position the pump in a dry area and ensure it is
accessible for any maintenance etc. that may be
necessary.
IMPORTANT: Ensure the ventilation slots on
the underside of the pump are free from
obstructions.
The hot water supply MUST NOT exceed 65°C
(149°F).
WARNING!
THE UNIT MUST NOT BE POSITIONED
WHERE IT WILL BE SUBJECT TO FREEZING
CONDITIONS.

INSTALLATION
Before commencing installation of the pump,
ensure the site conditions have been complied
with fully.
Also note the following:
• Pipework to precede wiring.
• The pump must be positioned in a dry area,
ideally in the linen/airing cupboard. It must be
well ventilated and not covered with towels
and sheets etc.
• Do not use with a combination water tank
system unless the cold water storage tank has
capacity of 114 litres (25 galls) or more.
• To assist in clearing air bubbles from the
system avoid using sharp bends where
possible. Flexible/swept fittings or formed
pipework is recommended.
• Ensure that all water supplies are isolated
before connection. Gate valves or full way
lever valves must be fitted immediately prior
to the pump. It is also advisable to fit a drain
off point on the lowest part of the system.
• NEVER use any form of soldered fittings on the
shower pump as this will damage the unit and
invalidate the guarantee.
• NEVER use solder within 300mm of the pump
or expose parts to a hot torch.
• Ensure mains electricity supply is SWITCHED
OFF before commencing electrical
connections.
• DO NOT OPERATE THE PUMP DRY. This may
cause damage to the seals and will invalidate
the guarantee.
Note: The pump motor has automatically
resetting thermal overload protection.
Procedure
aTurn off mains water and electrical supplies.
Drain the cold water cistern and hot water
cylinder and make a suitable connection to
the hot water supply.
bPosition the pump horizontally (with the
outlet ports in the upright position) with the
feet on a solid base so that it will not transmit
vibration.

connectors. Wait until the commissioning
procedure has been completed.
Note: Do not overtighten the connections on
the pump ports and take care to prevent any
system debris from entering the pump via the
connectors.
Wiring
gRemove the four retaining screws holding the
PCB cover (fig.5). Lift the cover together
with the variable speed control from the
pump body.
hThe 3-core cable from the mains electricity
supply can now be connected to the terminal
block situated on the PCB (fig.6). The size of
cable to use must be a minimum of 0.75mm.
Ensure the terminal block screws are fully
tightened and that no cable insulation is trapped
under the screws.

VARIABLE SPEED CONTROL
The variable speed control (fig.11) can be
adjusted to select the optimum performance of
the pump to suit personal preferences.
COMMISSIONING
Before the first operation of the shower pump, it
is necessary to flush out any system debris from
the installation. This operation must be carried
out with the pump isolated from the electricity
supply, and with the pump feed pipework from
the cistern and cylinder directed to waste by
connecting a suitable length of hose.
Procedure
1Ensure the isolating valves from the cistern
and cylinder are closed.
2Turn on the mains water supply to the
storage cistern and allow the cylinder and
system to fill.
3Open both isolating valves and flush
through thoroughly.
4Allow water to flow to waste for two or
three minutes to ensure any installation
debris and air is completely flushed from
the system.
5Check the system pipework for leaks.
6Close both isolating valves. Remove the
waste hoses and connect the cistern supply
pipework and cylinder pipework to the
pump inlet flexible push-in connectors.
7Remove the sprayhead from the mixer valve
hose and direct the hose to waste.
8Open the mixer valve fully and then re-open
both isolating valves.
9Allow water to flow under gravity from the
hose for a few minutes.
10 Stop the flow at the mixer valve.
11 Switch on the mains electricity supply to the
shower pump.
12 Open the mixer valve. The pump will
operate and water will flow. Allow water to
flow to waste for two or three minutes.
13 Check system pipework again for leaks.
14 Turn off the mixer valve – the pump will
switch off and the water will cease to flow.
Replace the sprayhead onto the shower
hose.
