CONNECTIONS Pump Type Voltage Inlet Outlet Fig.
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. 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.
Mounting Foot Securing Some pumps within the range are fitted with plastic mounting feet. If there is a requirement to secure the pump via the mounting feet, the following points should be noted. The pump should be mounted only in the horizontal position. Floor mounting is the preferred orientation but wall mounting is possible providing all fixing holes provided are used. *Air locking possible. Special care required to vent the pump casing Fig. 6 of air with this orientation.
ELECTRICAL INSTALLATION WARNINGS: The electrical installation must be carried out in accordance with the current national electrical regulations and installed by a competent person. Before starting work on the electrical installation ensure the power supply is isolated.
Diagram of earth continuity connection. Fig. 9 Certain installations may require additional earthing arrangements such as equipotential bonding. Reference should be made to the relevant regulations concerning this subject to ensure compliance. Wiring (Kennet range) This product range must be permanently connected to fixed wiring and is provided with a set of terminals which allow the connection of a flexible supply cord.
Supply Cord Extension (Thame, Loddon and X201 range) If the supply cord of the pump needs to be extended use the same specification as fitted to the product. Thame, Loddon and X201 range:- . . . . . . . . HO7RN-F3 G 1 mm², 10 Amp rating. Use an appropriate cable connector suitable for the cable specified, current involved and surrounding conditions. Fuses The following table gives the recommended fuse size for pump models fitted with a power cord at the factory.
Cable Gland & Supply Cord Fitting Instructions (Kennet single phase range) The cable gland assembly Fig. 12 (items 1 & 2) provides the necessary protection against ingress of solid objects and moisture as well as providing cable retention. Assembly instructions are as follows: 70 1. Ensure selected cable sheath 8 diameter is within the permitted N range (6.5 to 9.5 mm). E 2. Strip and prepare the cable sheath and insulators as L (Dims. in mm) shown in Fig. 10. 12 8 3.
Cable Gland & Supply Cord Fitting Instructions (Kennet three phase range) The cable gland assembly Fig. 15, (items 1 & 2) provides the necessary protection against ingress of solid objects and moisture as well as providing cable retention. Assembly instructions are as follows:80 1. Ensure selected cable sheath 8 diameter is within the permitted range (7.5 to 9.5 mm). L1 2. Strip and prepare the cable E sheath and insulators as shown L2 (Dims. in mm) in Fig. 13. L3 12 3.
Wiring Diagrams The supply cord and internal wiring within the terminal box are routed and secured to ensure compliance with the electrical standard EN 60335-1. It is essential that any disturbance of this internal wiring is avoided and the factory routing and securing of all internal wiring is always maintained.

1. System Flushing Some pumps incorporate plastic components that must not come into contact with solder flux, acid-based descalents or aggressive cleaning agents. The pipework system should be flushed out prior to the pump being connected, to ensure any contaminants/chemical residues and foreign bodies are removed from elsewhere in the system. 2. Liquid Supply Always ensure that liquid storage capacity is adequate to meet the demand. Ensure the pump chamber is full of liquid before starting the pump.

Starting a) Switch on power to the pump which will now be operational. b) If pump has a three phase supply, confirm the direction of rotation is correct by stopping and observing over run. The correct direction of rotation is anti-clockwise when looking directly at the front of the pump casing. To reverse rotation see wiring diagram section. c) The pump should now be fully operational.
Cleaners, Disinfectants and Descalents On installations where chemical disinfectants or descalents are periodically used, the compatibility of the chemical solution regarding the pump must be considered. Acid based descalents and aggressive cleaning agents must not come into contact with the pump. The pump must be removed from the system prior to the use of these products. The system should be flushed to remove all chemicals before the pump is re-connected.
