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).

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.
