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.
General: All models use a flow switch assembly which is directly connected to the pump discharge port. The wetted materials of construction are brass, stainless steel, strontium ferrite, nitrile and acetal. All models are supplied with a mains connecting lead and resilient mounting foot.

SITING OF THE PUMP / PIPEWORK WARNINGS: The motor casing can become very hot under normal operating conditions, care should be taken to ensure it cannot be touched during operation. 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 pump from frost and freezing.
Noise transmission in pipework can be reduced by fitting flexible hoses to pump inlet and outlet ports. An installation pack which includes flexible hoses is available, consult Stuart Turner for details. We do not recommend location of the pumps in the roof space, since air locks can easily result. If there is no alternative, please contact our technical sales department for advice. Pump Location (Hot Water Installation) 100 mm min Max. inlet head (consult limits of application section) Min.
It must be ensured that the storage capacity of the liquid supply is adequate for the flow rates required by the pump. The pipework feed to the storage tank should be of adequate size to ensure replenishment rate of tank is sufficient to meet the needs of the pump. The pump must be supplied with a dedicated feed direct from the liquid storage tank. Isolating valves should be fitted in suction and delivery pipework to enable easy isolation and access to the pump.
Pipework Connections (Hot Water) (RGFL, RGDFL and ESFL range) These pumps should have a minimum of 22 mm pipework throughout the system. The supply must be air free and connection to the cylinder can be made by one of the following methods shown. When method of connection is to be via the expansion pipe, the cold water storage cistern should be at least 1 metre above the top of the hot water cylinder. Off expansion pipe with rising 28 mm offset reducing to 22 mm pipework to pump and expansion pipe.
Electrical Connection The motor is provided with a factory fitted supply cord. This must be permanently connected to the fixed wiring of the mains supply. Means for disconnection must be incorporated in the fixed wiring in accordance with the wiring rules. A suitable method of connection would be via a double pole switched, fused connection unit complying with BS 1363-4, protected with a fuse (see fuse section).
Wiring Of Connection Unit WARNING: This appliance must be earthed. The wires in the mains lead (supply cord) are coloured in accordance with the following code: Green and Yellow:- Earth. Blue:- Neutral.

Supply Cord Replacement If the supply cord is to be changed or is damaged, it must be replaced with a special cord assembly available from Stuart Turner or one of their approved repairers. On disassembly note the cord retention and routing system. Reassemble to the same pattern. For information on cable connection consult the wiring diagram and cable gland fitting instructions.
NOISE The equivalent continuous A-weighted sound pressure level at a distance of 1 metre from the pumpset does not exceed 70 dB(A). COMMISSIONING WARNINGS: The motor casing can become very hot under normal operating conditions, care should be taken to ensure it cannot be touched during operation. Do not run pump without guards and terminal box lid correctly fitted. The pump chamber must be full of liquid at all times. Seal damage will result if the pump runs dry. 1.
Priming Plug Priming Plug ESFL KFL Priming Plug Priming Plug RGFL, RGDFL Fig. 14 LFL b) Vertical suction models This pump range are self venting and hence no priming plugs are fitted. Turn on liquid supply and open outlet valve to allow pump to fill and vent. 4. Pre-Start Check Always ensure the pump is in a positive head position with flooded suction. A gravity flow of approx. 0.6 l/min (RGFL/ESFL) or approx.
d) Carefully check pump and pipework for leaks whilst pump running and stationary before leaving the installation unattended. For Further Technical Support Phone the Stuart Turner Pump Assist team on 0844 98 000 97. Our staff are trained to help and advise you over the phone or arrange for a service engineer to call. Note: When pumps are installed in another manufacturers original equipment, please contact the manufacturer for advice.
TROUBLE SHOOTING GUIDE Symptoms Probable Cause Recommended Action Pump will not start. No liquid. Check required gravity flow of liquid is available to the fittings of approx. 0.6 l/min (RGFL/RGDFL/ESFL models) or approx. 1 l/min (KFL & LFL models). Liquid supply. If NO... check liquid level in the supply tank and all stopcocks are open. Filter blocked. Remove and clean system filters. Electrical supply. Check wiring connections.
Flow Switch Circuit Test 1. First confirm visually that the flow switch reed clamp has not been dislodged during handling or installation. The clamp must be fully located within its flow switch body groove as shown. 2. To carry out the following test you will need to obtain a magnet, a typical fridge magnet is suitable. 3. Ensure the power supply is switched on. 4. Position the magnet directly in front of the reed clamp as shown.
