Installation, Operation & Maintenance Instructions Please leave this instruction booklet with the owner as it contains important guarantee, maintenance and safety information Read this manual carefully before commencing installation. This manual covers the following products: Monsoon Extra S1.4 bar Pt. No.
PRODUCT DESCRIPTION Electric motor driven centrifugal pump complete with an automatic control system, consisting of flow switches and electronic controls. APPLICATION The Monsoon Extra Standard Single range is designed for pressure boosting applications in vented stored, hot or cold, clean water systems, where under gravity, a flow of at least 1 l/min is available. Inlet pressures to the pump and ambient temperatures must not exceed the values given in the technical specifications.
CHECKLIST 28 mm copper outlet pipework (discharge). 28 mm isolating valve (non restrictive) and fittings (not supplied) to allow easy pump service. Short 28 mm copper pipe tails to connect between isolating valve and flexible pipes. 28 mm - G 1 connector (not supplied) must be fitted 28 mm flexible pipes. These hoses are fitted with G 1 female connector suitable for connection to a G 1 (1 “ BSP) adaptor or fitting.
1 READ BEFORE COMMENCING PUMP INSTALLATION A. Water storage capacity. 1.11 The stored water storage capacity to be pumped, must be sufficient to meet the flow rates required by the pumped equipment and any other water using fittings and appliances, which may be operated simultaneously. 1.12 Ensure the pump is primed as described in the priming section before starting, damage to the shaft seal will result otherwise. See Section 5 - Commissioning. B.
2 LOCATION - GENERAL 2.16 2.17 2.18 2.19 2.20 2.21 2.22 2.23 2.24 2.25 2.11 Access: For emergencies and maintenance the pump must be easily accessible. 2.12 Protection: The pump must be located in a dry position, frost free and protected from freezing, particularly when installed in a loft (not recommended). 2.13 Ventilation: Ensure an adequate air flow to cool the pump. Separate the pump from other appliances that generate heat. An 80 mm (3 “) air gap must be maintained around the pump. 2.
Static inlet pressure 10 metres max 1 metre min 2 LOCATION - BLENDED WATER INSTALLATION Outlet head must be below bottom of cold water tank and able to pass a minimum of 1 l/min of gravity flow Fig. 2 2.26 Location: The pump must, for optimum performance, be sited as close as possible to and never more than 4 metres from the HOT WATER cylinder. The pump should always be sited BELOW the HOT WATER take-off from the cylinder.
Static inlet pressure 10 metres max 1 metre min 2 LOCATION - HOT WATER INSTALLATION Outlet head must be below bottom of cold water tank and able to pass a minimum of 1 l/min of gravity flow preferred area Fig. 4 2.28 Hot water supply: The pump must be supplied with a dedicated feed direct from the hot water cylinder or storage tank which should be via a secondary dedicated tapping (see Fig. 5). Do not connect to the mains. Fig. 5 Factory installed secondary tapping with 28 mm pipework to pump. Cont .
Least preferred area Max. inlet head 10 m Min. inlet head 1 m 200 mm min. 2.29 Non-Preferred Pump Location: The pump must be located with at least 1 metre flooded suction at all times. 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. This risk must be eliminated.
4 ELECTRICAL INSTALLATION / EARTHING 4.11 Regulations: The electrical installation must be carried out in accordance with the current national electrical regulations and installed by a qualified person. 4.12 Safety: In the interests of electrical safety a 30 mA residual current device (R.C.D. not supplied) should be installed in the supply circuit. This may be part of a consumer unit or a separate unit. 4.13 Before starting work on the electrical supply ensure power supply is isolated. 4.

5 COMMISSIONING / SYSTEM FLUSHING/ PRIMING / STARTING 5.11 System Flushing: 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. 5.12 Water Supply: Always ensure that water storage capacity is adequate to meet the demand. Ensure the pump chamber is full of water before starting the pump. Failure to do this could result in seal damage.
6 MAINTENANCE 6.11 Turn off water supplies to the pump and release pressure by opening water outlets before attempting maintenance. 6.12 Inlet strainer: Incorporated in the strainer is a removable gauze filter which may require periodic cleaning. The frequency of this operation is dependent upon installation conditions. The strainer is located in the inlet pipework to the pump (Fig. 11). The gauze filter is removed as follows:a) Isolate pump electrically. b) Release all system pressure.
