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: CHM160-30 B CHM160-50 B Pt. No. 46607 Pt. No. 46609 CHM160-40 B CHM160-60 B Pt. No. 46608 Pt. No.
PRODUCT DESCRIPTION Electric motor driven centrifugal pump complete with an automatic control system, consisting of flow switch, pressure switch, pressure vessel and electronic control. APPLICATION The Stuart CHM Boostamatic range is designed for pressure boosting applications in vented stored, hot or cold, clean water systems, where under gravity, no flow is available. Inlet pressures to the pump and ambient temperatures must not exceed the values given in the technical specifications.
CHECKLIST IMPORTANT: With the pump removed from its packaging check for any damage prior to installation. If any damage is found contact Stuart Turner Ltd within 24 hours of receipt.

PRE-INSTALLATION ASSEMBLY Re-positioning of Pressure Vessel The pressure vessel can be rotated to alternative positions (Fig. 3) in the event of the factory fitted position being unsuitable for a specific installation. a) Remove pressure vessel by unscrewing anti-clockwise. b) Using a 2 mm allen key, carefully loosen all three retaining grub screws by two turns (Fig. 2).
1 READ BEFORE COMMENCING PUMP INSTALLATION A. Water storage capacity. 1.11 The hot and cold water storage capacity 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 4 - 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.
Cold water pump Static outlet pressure Max. 13 m Static inlet pressure Min. 1 m Max. 10 m 2 LOCATION - COLD WATER INSTALLATION Fig. 4 2.26 The cold water supply: The supply must be AIR FREE and have a DEDICATED CONNECTION to the tank which should be via a tank connector, positioned at a slightly lower level (25 mm minimum) than the feed pipe to the hot water cylinder. Do not connect to the mains. Cont ...
Static outlet pressure Max. 13 m LOCATION - HOT WATER INSTALLATION Static inlet pressure Min. 1 m Max. 10 m 2 Hot water pump Fig. 5 2.27 Hot water cylinder or storage tank: 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 28 mm. 2.
350 mm min. Least preferred area Max. inlet head 10 m Min. inlet head 1 m 2.30 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.
3 ELECTRICAL INSTALLATION / EARTHING 3.11 Regulations: The electrical installation must be carried out in accordance with the current national electrical regulations and installed by a qualified person. 3.12 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. 3.13 Before starting work on the electrical supply ensure power supply is isolated. 3.

4 COMMISSIONING / SYSTEM FLUSHING/ PRIMING / STARTING 4.11 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. 4.12 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.
5 MAINTENANCE 5.11 Turn off water supplies to the pump and release pressure by opening water outlets before attempting maintenance. 5.12 Pressure vessel: The pressure vessel should be checked once every 6 months to have its air charge checked or replenished, this should be carried out as follows:a) Isolate pump electrically. b) Isolate the water supply by closing the appropriate isolating valves. c) Release system water pressure by opening a system outlet on the system.

7 TROUBLE SHOOTING GUIDE Symptoms Probable Cause Recommended Action Pump will not start. Electrical supply. Check power supply. Check fuse (see fuse section). Check circuit breaker is set. Check wiring connections. Pump Jammed. If motor ‘Buzzes’ switch off power and contact Stuart Turner. Damaged pressure switch. Turn off power. Release system water pressure. Turn on power, pump should start. If NOT contact Stuart Turner. Recommended static inlet/outlet heads exceeded.
7.11 Dry Run Protection: This pump is fitted with a safety control circuit, which will detect the following fault condition: Dry running caused by water starvation to the pump. Should the pump run out of water it will stop as part of a “protective logic sequence”, detailed below. The fault should be rectified before re-starting the pump. Check that there is sufficient water supply to the pump and also ensure that all terminal fitting outlets are closed. 7.
Briefly reconnect the mains power supply to the pump – the indicator light should illuminate if the pump has been correctly wired. Isolate the mains electrical power supply from the pump. Re fit the terminal box lid ensuring no cables are trapped. Re fit the four terminal box lid retaining screws, tighten to 0.8 Nm.
