Electric motor driven single or twin ended peripheral pumps complete with an automatic

control system, consisting of flow switches, pressure switches, pressure vessels and

electronic control.

APPLICATION

Showermate Universal pumps are suitable for positive or negative head installation

conditions. The pumps are designed for single shower pressure boosting applications in

vented stored water systems. Inlet pressures to the pump and ambient temperatures must

not exceed the values given in the technical specifications.

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.

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.

WARNING - Washer/condenser dryers and condenser dryers.



The pump must not be used in the water supply line to a washer/

condenser drier or a condenser drier, which uses a constant flow of

cold water to aid the condenser drying process, as damage can occur

to the pump. If in doubt or for further information contact Stuart

Turner Ltd.

Page 3: Pump Location
STEP 1: PUMP LOCATION WARNINGS: Pump Location  If possible site the pump in a location where in the unlikely event of a water leak, any spillage is contained or routed to avoid electrics or areas sensitive to water damage. Care should be taken to protect pump from frost and freezing, ...
Page 4 Twin Pump Installation Preferred Pump Location (shaded area). Pump at a level below draw off tapping in cylinder. hot water services Fig. 3 If it is not possible to locate the pump in the preferred area due to site limitations and it is necessary to position the unit in the loft, or in a position above the secondary tapping that feeds the pump, then there is an increased risk of air locks.
Page 5 Single Pump Installation Cold Water Installations Fig. 5 Before deciding where to locate the unit, check to ensure the static inlet head (Fig. 5) meets the minimum requirement of 0.5 metres and does not exceed the maximum requirement stated. The static outlet head (Fig. 5) must also be within the maximum requirement stated. Hot Water Installations The preferred pump location is at floor level next to the hot water cylinder or a level that is below the secondary tapping that feeds the pump.
Page 6 Before deciding where to locate the unit, check to ensure the static inlet head (Fig. 6) meets the minimum requirement of 0.5 metres and does not exceed the maximum requirement stated. The static outlet head (Fig. 6) must also be within the maximum requirement stated. Hot Water Installations If it is not possible to locate the pump in the preferred area due to site limitations and it is necessary to position the unit in the loft, or in a position above the secondary tapping that...
Page 7: Pipework
STEP 2: PIPEWORK (General) WARNINGS: Ensure pipework to and from pump is independently supported to  prevent forces being transferred to inlet and outlet branches of pump. Do not introduce solder flux to pumps, pump parts or hoses  manufactured from plastic. All solder joints should be completed and flux residues removed prior to pump connection.
Page 8: Pump Connections
Pipework Connections (Hot) When a hot water cylinder or storage tank is used, ensure the pipework size from the cold water storage to the hot water storage is of adequate size and a minimum of 22 mm. The pump must be supplied with a dedicated feed direct from the hot water cylinder or storage tank.
Page 9 Pumps supplied with flexible inlet and outlet hoses Flexible pipes are supplied with this pump variant. The pump inlet and outlet ports are threaded G ¾ male. These ports are provided with a flat sealing face suitable for use with an appropriately sized flat faced fitting and fibre or rubber washer.
Page 10 Hose to pipework (Release and connection of push-in connectors) 1. The hoses are fitted with plastic push-in connectors, which must only be connected with the following: a) 15 mm diameter copper pipe to BS EN 1057 - R250 (half hard) - Table 3. b) 15 mm plastic pipe to BS 7291 part 1 and part 2 (Table 1), or part 3 (Table 1) plus internal support sleeve*.
Page 11 Pump Connections (General) In the case of horizontal feeds use a 15 mm compatible stem elbow (not supplied). Do not bend the hose more than 30° as they may become Inlet damaged, transmit noise or leak. 22 mm Inlet pipework fed from water storage system.
Page 12: Electrical Installation
STEP 4 ELECTRICAL INSTALLATION WARNINGS: The electrical installation must be carried out in accordance with the  current national electrical regulations and installed by a competent person. In the interests of electrical safety a 30 mA residual current device  (R.C.D.) should be installed in the supply circuit.
Page 13 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 Brown: Live As the colours of the wires in the mains lead of this appliance may not correspond with the coloured markings identifying the terminals in your connection unit proceed as follows: The wire which is coloured green and yellow must be connected to the terminal in the connection unit which is marked with the letter E or by the earth symbol:...
Page 14 Supply Cord Replacement 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 prior to any disturbance of this internal wiring, all cable routing and securing details are carefully noted to ensure re-assembly to the same factory pattern is always maintained.
Page 15: Commissioning
STEP 5 COMMISSIONING WARNINGS: The motor casing can become 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 water at all times.
Page 16: Maintenance
MAINTENANCE WARNINGS: Care should be taken to protect pump from frost and freezing,  particularly when located in a loft installation. Pump Location  If possible site the pump in a location where in the unlikely event of a water leak, any spillage is contained or routed to avoid electrics or areas sensitive to water damage.
Page 17 Pressure vessel Schrader valve Single pump shown Fig. 19 e) Replenish air charge if required by injecting air into the vessel via the Schrader valve using a car or bicycle pump, ensuring a system outlet valve (tap) remains open during this procedure to allow the vessel to exhaust any excess water. f) Close all system taps, open hot and cold inlet pump isolating valves, turn on electrical power.

Page 19: Noise
NOISE The equivalent continuous A-weighted sound pressure level at a distance of 1 metre from the pump does not exceed 70 dB(A). TROUBLE SHOOTING GUIDE Symptoms Probable Cause Recommended Action Pump will not start. Electrical supply. Check wiring connections. Check all switches are ‘on’. Check fuse (see fuse section).
Page 20: Environment Protection
Flow Switch Circuit Test 1) To carry out the following test you will need to obtain a magnet. 2) Ensure the power supply is switched on. 3) Position the magnet directly in front of the reed switch box as shown. If pump does not start, then slowly move the magnet up and down to a position that exceeds the extent of the reed switch box.
Page 21 GOOD PRACTICE Always flush system prior to installing a new or serviced pump. Always ensure both sides of the pump are primed (filled with water) before starting the pump. DO NOT RUN PUMP DRY. Always ensure the pump has a flooded suction. Always ensure anti-vibration feet are used.
