IMPORTANT NOTES
Please read these instructions fully before starting the installation:
The installation must comply with the relevant water supply, electrical and building regulations and be installed by a competent person.
If in doubt, consult Stuart Turner Ltd.
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.
Children should be supervised to ensure that they do not play with the appliance.
APPLICATION
The range of stainless steel peripheral pumps is designed to pump clean fresh water. Other clean, non aggressive, non explosive liquids with similar characteristics to water may be pumped. Consult Stuart Turner for such applications.
The pumps can be used for pressure boosting, fluid transfer and distribution. They are suitable for flooded suction applications. Alternatively a maximum suction lift of 4.6 m is permitted when using a Stuart footvalve/strainer.
WARNING AGAINST MISUSE
This pump set must not be used for any other application without the written consent of Stuart Turner Limited. In particular, it 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/PIPEWORK
WARNINGS:
Pump Location
If possible site the pump in a location where in the unlikely event of a liquid leak, any spillage is contained or routed to avoid electrics or areas sensitive to liquid damage.
Care should be taken to protect the pump from frost and freezing.
Ensure pipework to and from pump is independently supported to prevent stress on the pump inlet and outlet branches.
Do not fit a non-return valve, or devices which contain non-return valves, in the suction (inlet) pipework to the pump. Exceptions can be made in the case of suction lift installations when a footvalve is required.
-4 -
When a footvalve is required on installations that incorporate automatic pump control, it is recommended that a suitable pressure relief valve be fitted in the discharge (outlet) pipework from the pump.
Do not run against a closed valve for periods longer than 5 minutes.
Do not allow plastic pump parts to come into contact with oil or cellulose based paints, paint thinners or strippers, acid based descalents or aggressive cleaning agents.
Do not introduce solder flux to pumps or pump parts manufactured from plastic. All solder joints should be completed and flux residues removed prior to pump connection.
Always install isolating valves to both suction and delivery pipework.
The motor casing can become very hot under normal operating conditions. Care should be taken to ensure it cannot be touched during operation.
Site the pump in a dry, frost-free horizontal position where it cannot be sprayed with water and as close to the liquid source as possible.
The pump enclosure must be ventilated and there should be a minimum clearance of 80 mm between the pump and housing on all sides.
To prevent loss of pressure through pipework, use pipe size to match pump whenever possible, minimising 90° bends.
It must be ensured that storage capacity of the liquid supply is adequate for the flow rates required by the pump.
The pipework feeds to the storage tank should be of adequate size to ensure replenishment rate of tank is sufficient to meet the needs of the pump.
Isolating valves should be fitted in suction and delivery pipework to enable easy isolation and access to the pump.
When the pump is to be installed in areas where there is a risk of debris or scale build up within the system, it is recommended that the inlet pipework is fitted with an inline strainer.
Pump Mounted Above Liquid Source (Suction Lift)
The pumps can be used in a suction lift installation providing the height of lift is within the limits specified in the limits of application section.
A footvalve and strainer must always be used and the suction pipework size should be 22 mm throughout.
Lay the suction piping over the shortest possible distance and ensure there is a constant rise from the liquid source to the pump. Any high spots will cause air pockets to form, reducing system efficiency.
Ensure all joints in suction pipework are completely airtight. Failure to comply will result in loss of prime.
The intake of the footvalve/strainer should be positioned such that is cannot be blocked with debris or silt that are frequently found in the bottom of sumps and wells.
