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).

2 ELECTRICAL 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.

INTRODUCTION

This book contains all the necessary fitting
and operating instructions for your Triton twin
impeller power shower pump. Please read them
carefully.

This product is rated at:

15 minutes on / 60 minutes off.

Care taken during the installation will ensure a
long and trouble free life from your unit.

IMPORTANT: All plumbing connections must
be completed before making the electrical
connections.

Please read through the whole of this book
before beginning your installation.

SAFETY WARNINGS

a. Under no circumstances must this pump

be connected to a mains cold water
supply. Failure to comply will invalidate the
guarantee.

b. The shower pump MUST NOT be used if

suspected of being frozen.

c. The pump must be earthed.
d. Switch off immediately at isolating switch if

water ceases to flow during use.

e. DO NOT operate the unit outside the

guidelines laid out in “site requirements”.

f. This pump is to be used for providing water

to a shower only.

In the interest of 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.
