PRODUCT DESCRIPTION
Electric motor driven submersible pump with float switch control.
APPLICATION
The submersible pump range is designed for re-circulation, drainage and transfer of fresh
water in outdoor or indoor applications.
The pumps incorporate an integral float switch, which provides automatic pump control in
the form of a low level cut out to prevent the risk of dry running.
The pumps are suitable for dirty water applications and are capable of handling semi-
solids in suspension of up to *5 mm in diameter.
*Note: Applicable only when pump is suspended above bottom of sump. When pump is
located on the bottom of sump the inlet grille will restrict solid ingress diameters to 3 mm.
The pumps must not be used with salt water,
sewage, flammable, corrosive or explosive liquids
(eg. petroleum oil, petrol, thinners) grease, oils or
foodstuffs.
This appliance can be used by children aged from
8 years and above and persons with reduced
physical, sensory or mental capabilities or lack

1 IMPORTANT FACTS: READ BEFORE COMMENCING PUMP INSTALLATION
A. Water temperature
The water entering the pump must be controlled as follows:
1.11 The maximum allowable water temperature is 35 oC.
1.12 The minimum allowable water temperature is 4 oC.
B. Pipework - General
1.13 All models are supplied with a 90oelbow and stepped hose connector (see pump
connection section for details) which can be screwed directly into the pump
discharge connection.
1.14 The hose connector is suitable for a range of flexible hose sizes and can be cut
to suit the selected size. For best flow use the largest bore pipe possible
minimising 90° bends. Small pipe sizes will reduce the pump performance.
C. Electrical Installation Regulations
1.15 The electrical installation must be carried out in accordance with the current
national electrical regulations.
1.16 The electrical installation must be installed by a qualified person.

2 LOCATION - GENERAL
2.11 Access: For emergencies and maintenance the pump must be
easily accessible.
2.12 Do not run against a closed valve for periods longer than 5 minutes.
The water in and around the pump must not be allowed to freeze.
This will result in pump damage.
2.13 Do not under any circumstances use the supply cord fitted, as a
means to carry or lower the pump into position on installation. Attach
a rope sling to handle.
2.14 Pump position: When siting the pump ensure its base is raised
slightly from the bottom of the sump reducing the possibility of
blocking the filter with debris or drawing in small stones (see Fig. 2).
2.15 The pump must be installed in the vertical position and must be fully submerged
at all times when operating continuously to avoid overheating of the motor.
However, when the automatic float switch option is selected, the pump may be
operated partially submerged for short periods (see float switch operation
section for further details).
2.16 When siting the pumps in a location where organic or general debris is likely,
ensure the pump is placed on its base on a flat horizontal surface (eg. on a
paving slab) to enable full functionality of the inlet filter grille and to prevent the
force of the pump from drawing in small stones. This will result in pump
damage.
2.17 Float Switch: The pumps incorporate an integral automatic float switch which
has two modes of operation, auto and manual.
The float switch consists of a float which moves up and down on a vertical axis
within a housing.
2.18 Sump Size: The minimum possible sump
size is 270 mm x 170 mm.

2.19 Float Switch Operation: The float switch operation mode is changed by
moving the selection lever (1) either up for the Manual position or down for the
Auto position.
2.20 Automatic Operation (Switch Position ‘Down’): The integrated float starts
and stops the pump automatically when the selection indicator is set to
automatic. It also provides a low level cut out to prevent dry running.
2.21 Manual Operation (Switch Position ‘Up’): To start the pump, lift the selector
lever (1) to the up position. This will cause the pump to run continuously. In this
condition the pump will empty the sump down to a level of 3-6 mm.
The pump must then be stopped to avoid dry running and pump damage.

accordance with the current national electrical regulations and
installed by a qualified person.
4.12 Safety: In the interests of electrical safety a 30 mA residual current
device (R.C.D. not supplied) should be installed in the supply circuit.
This may be part of a consumer unit or a separate unit.
4.13 Before starting work on the electrical supply ensure power supply is
isolated.
4.14 Isolate all appliances in the water from the electrical supply before
putting your hands in the water.
4.15 The power supply cord of this pump cannot be replaced. If the cord is
damaged, the pump should be disposed of (see Section 8.11).
4.16 If the pump is used to empty a swimming pool, the pump must not be

4.17 All motors are thermally protected by an integral auto-resetting thermotrip and
are rated for continuous use.
4.18 Earthing: This appliance must be earthed via the supply cord.
4.19 Connections: The motor is provided with a factory fitted supply cord and plug.
This must be connected to the mains supply via a 13 Amp double pole switched,
socket outlet in compliance with BS 1363-2.
The socket outlet should be mounted in an easily accessible position and should
be labelled if confusion is possible, to allow easy identification of the pump
isolating switch.
4.20 Wiring Of Connection Unit:
The moulded plug fitted to this appliance is not waterproof - keep dry.
If the plug supplied is not suitable for your socket outlet, it should be cut off and
destroyed.
A plug with bared flexible cords is hazardous if engaged in a live socket
outlet.
The end of the flexible cord should be suitably prepared and correct plug fitted
as follows:
The wires in the mains lead (supply cord) are coloured in accordance with the
following code:
Green and Yellow: Earth Blue: Neutral Brown: Live

5 COMMISSIONING
5.11 The pump chamber must be full of water at all times. Damage will result if pump
runs dry.
5.12 The pump must be fully submerged before starting. Take care when submerging
the pump to ensure all air is purged from the casing. This is done by slowly
submerging the pump and gently agitating whilst doing so. This will enable any
trapped air pockets to be released.
5.13 Turn on the electrical supply and water movement should be immediately evident
from pump outlet. If it is not, repeat step 5.12.
5.14 For Further Technical Support: Phone the Stuart Turner PumpAssist team on
[phone]. Our staff are trained to help and advise you over the
phone.
Note: When pumps are installed in another manufacturers original equipment,
please contact the manufacturer for advice.
If an extension cord is necessary a cord of the proper type and rating must be
used.
In general for 230 volt pumps on distances up to 40 metres (inclusive of original
cord length) the same specification cord as fitted to the pump can be used.
For distances above 40 metres a larger cord size may be required due to voltage
drop and advice must be obtained based upon installation details.
Any connectors or junction boxes must be specifically suited for outdoor use
and installed in accordance with manufacturers instructions.
Any cable routed underground must be protected to local standards.
