IMPORTANT NOTES
z Please read these instructions fully before starting the
installation:
z The installation must comply with the relevant water supply,
electrical and building regulations and be installed by a
competent person.
z If in doubt, consult Stuart Turner Ltd.
APPLICATION
General
z The pumps must not be used with salt water, sewage, flammable,
corrosive or explosive liquids (eg. petroleum oil, petrol, thinners)
grease, oils or foodstuffs.
z This appliance is not intended for use by persons (including children)
with reduced physical, sensory or mental capabilities, or lack of
experience and knowledge, unless they have been given supervision
or instruction concerning use of the appliance by a person responsible
for their safety.
z Children should be supervised to ensure that they do not play with the
appliance.
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.
- 2 -
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.
WARNING AGAINST MISUSE
This pump set must not be used for any other application without the
written consent of Stuart Turner Limited and in particular, must not be
connected directly to the mains water supply or used outside the
conditions specified in the limits of application.

SITING OF THE PUMP
WARNINGS:
z Do not run against a closed valve for periods longer than 5 minutes.
z The water in and around the pump must not be allowed to freeze. This
will result in pump damage.
z 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.
z Do not allow plastic pump parts to come into contact with solder flux,
oil or cellulose based paints, paint thinners or strippers, acid based
descalents or aggressive cleaning agents.
z 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.
General
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).
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.
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.
Sump Size
The minimum possible sump size is
270 mm x 170 mm.
