Important Safety information
1
1.12 DO NOT use jointing compound on any pipe
fittings, use only the flexible hoses supplied
to connect to the pump.
Plumbing
1.1 All installations must comply with Water
Regulations/Bylaws.
1.13 It is strongly recommended that copper pipe
is used for the installation to avoid nuisance
tripping of the pump.
1.2 DO NOT connect the pump unit to the
mains water supply.
2
1.3 Supply pipes must be flushed thoroughly to
clear debris and flux before connecting to the
pump and shower.
Electrical
2.1 The installation must be undertaken by a
suitably competent person and comply
with BS7671 “Requirements for electrical
installations” (IEE wiring regulations) and
building regulations. Make sure the hot and
cold water connections to the pump are
adequately bonded.
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.
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.
1.6 DO NOT solder pipes or fittings within
300mm of the pump, as heat transfer can
damage the components.
2.3 The mains supply must be 230V 50Hz,
connected to the pump via a double pole
switched connection unit fused at 5 Amps,
having a contact separation of at least 3mm
in all poles.
1.7 The pump must be connected to dedicated
water supplies. Do not fit the pump to a
common supply.
1.8 The 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. This also helps to prevent
nuisance tripping of the pump.
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), also known as a
residual current circuit breaker (RCCB),
should be installed in the supply circuit.
This may be part of the consumer unit or a
separate unit.
1.9 The action of the pump is to increase the
flow rate. If the supply pipe work cannot
handle the resulting flow rate then:
1.9.1The anticipated flow rate may not be
achieved.
2.6 The wires in the supply cable are coloured in
accordance with the following code:
1.9.2Air may be drawn into the hot supply
from the vent pipe causing spluttering and
temperature fluctuations at the showerhead.
1.10 A high level hot feed pipe must not rise
above the level of the water in the cistern.
To reduce the risk of air locks pipes should
be run level with or below the base of the
cistern.

The supply cable can only be replaced by the
manufacturer or an authorised agent.
2.7 Always disconnect the supply before any form
of work or maintenance on the pump.
1.11 Pipe runs must be as short as possible and
standard full flow isolating gate valves or
lever valves MUST be fitted to both inlet and
outlet sides of the pump as an independent
means of isolating the water should
maintenance or servicing be necessary.
Replacement parts can be ordered from Triton
Customer Service. See ‘spare parts’ for details.

warning!
This pump is designed to supply
water to a shower only.
The installation must be in accordance with
Water Regulations and Bylaws.
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 storage cylinder). The hot water cylinder
should have a minimum capacity of 136 litres
It is advisable to check that the replenishment
rate from the float operated valve meets the
output requirements.
Both the hot and cold water supplies to the
pump must be direct and not significantly
affected by any other outlets or connections.
Fig.2 shows the two recommended installation
methods:
1. The connection can be taken via a tee
connection on the underside of the rising
angled section of pipe work from the cylinder.
2. The connection is taken directly from the hot
water storage cylinder via a “No Stop Essex
flange”.
Shower pump
Electrical requirements
To comply with BS6700 the hot water storage
temperature should not exceed 60ºC. Operation
at this temperature will also reduce the rate of
formation of limescale in the system. The water
supply must not exceed 65ºC (149ºF).
WARNING!
THE PUMP MUST BE EARTHED.
THE PUMP MUST NOT BE CONNECTED TO
THE MAINS COLD WATER SUPPLY.
The pump must be connected to a 230V 50Hz
electrical supply, via a double pole switch having
a contact separation of at least 3 mm in all poles.
This can be a ceiling mounted pull cord switch
in the shower room, or a wall mounted switch in
a nearby room.
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 guarantee correct operation of the flow
switches, all pipe work must be below the cold
water cistern and the showerhead must be at
least 1 metre below the surface of the water in
the cold water cistern.
The pump installation must be fused at 5 amps.
A Residual Current Circuit Breaker (RCCB) also
known as a Residual Current Device (RCD)
having a tripping current not exceeding 30mA
should be installed in the supply circuit. This may
be part of the consumer unit or a separate unit.
In situations where this 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 225 litres
(50 gals) to avoid starvation of water to the
pump, and a minimum head of water of
1 metre.
Note: The installation 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, so that the pump cannot
be sprayed with water, and such that a person
using a fixed bath or shower cannot access the
pump without using tools.

a. Turn 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.
b. Position the pump horizontally (with the
ports in the upright position) with the feet
on a solid base so that it will not transmit
vibration.
Note: The pump must only be placed in the
horizontal position.
c.
Connect the inlet flexible connectors to the
inlet ports of the pump ensuring the filters
are in position on the inlets (fig.3).
Filter
The hot and cold supplies can be connected
to either end of the pump.
d. Connect the outlet flexible connectors to the
outlet ports of the pump.
e.
Connect the hot and cold feed pipes from
the mixer valve to the outlet flexible push-in
connectors.
f.
At this stage, do not connect the hot
and cold water supplies from the cistern
and cylinder to the inlet flexible push-in
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.
Electrical connections
Switch off the electricity supply at the
mains.
Connect the pump via a double pole switch
having a contact separation of at least 3mm in all
poles with a 5 Amp fuse.
The wires in the supply cable are coloured in

Shower pump
Commissioning
Note: If care has been taken to prevent any
obvious debris entering the system, the above
procedure should be adequate for normal
operating conditions of the pump and shower.
However, it may be advisable to also clean the
filters in the inlet ports of the pump as an extra
precaution.
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.
Cleaning
Procedure
Clean the unit with a damp cloth using clean
water or ­mild liquid detergent.
1. Make sure the isolating valves from the
cistern and cylinder are closed.
2. Turn on the mains water supply to the
storage cistern and allow the cylinder and
system to fill.
3. Open both isolating valves and flush
through thoroughly.
4. Allow water to flow to waste for two or
three minutes to make sure any installation
debris and air is completely flushed from
the system.
5. Check the system pipework for leaks.
6. Close both isolating valves. Remove the
waste hoses and connect the cistern supply
pipework and cylinder pipework to the
pump inlet flexible push-in connectors.
DO NOT use acid or abrasive detergents.
7. Remove the showerhead from the mixer
valve hose and direct the hose to waste.
8. Open the mixer valve fully and then re-open
both isolating valves.
9. Allow 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 showerhead onto the shower
hose.
15. Switch off the electric supply to the pump
and eliminate any leaks.
