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 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.

Do not connect to the mains. 2.
Hot water connection: (Applicable to S1.5, S2.0, S3.0 and S4.0 bar Twins, S2.0, S3.0 and S4.5 bar Singles) 2. 29 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 22 mm for all models except the S4.5 bar twin which should be a minimum of 28 mm. 2.
3 PUMP CONNECTIONS Do not use stainless steel, chrome or nickel plated pipe with the flexible hose push-in plumbing connections. Do not introduce solder flux into the joint or surrounding area as connectors will be attacked and may fail. All solder joints should be completed and flux residues removed before final connection to push-in connections, on the flexible hose.
3.12 Hose to pipework: 1. The hoses are fitted with plastic push-in connectors, which must only be connected with the following: a) 22 mm diameter copper pipe to BS EN 1057 - R250 (half hard) - Table 3. b) 22 mm plastic pipe to BS 7291 part 1 and part 2 (Table 1), or part 3 (Table 1) plus internal support sleeve*. * The internal bore of the plastic pipe must be supported against collapse with the pipe manufacturers recommended support sleeve (pipe insert).
5. To break the joint, push pipe firmly into fitting, hold collet down and gently remove pipe. If the system has been filled with water care should be taken to isolate pump and towels used to absorb spilled water. 3.13 Typical Low Level Installation: In certain installations it may be necessary to install a 90° bend on the inlet or outlet connections of the pump before the flexible hose to accommodate a low level installation. Below are some preferred connection options.
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.
The wire which is coloured blue must be connected to the terminal which is marked with the letter N or coloured black. The wire which is coloured brown must be connected to the terminal which is marked with the letter L or coloured red. 4.21 Wiring Diagrams: Parallel wiring of two single pumps is not recommended.
4.24 Cable Gland Fitting Instructions: 1 2 Fig. 14 To enable correct assembly of the cable gland the ‘O’-ring (Fig. 14 item 1) must be placed over the cable before the clamping insert (Fig. 14 item 2) can be tightened. Note: Cable diameter range:- 6.5 mm to 9.5 mm. 4.25 Supply Cord Extension: The pumps are fitted with a supply cord to the following specification:All models . . . . . . . . . . . . . . . . . . HO5VV-F3 G 0.75 mm² - 6 Amp rated cable.
5 COMMISSIONING 5.11 System Flushing: This pump incorporates push-in connectors and 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. 5.12 Water Supply: Always ensure that water storage capacity is adequate to meet the demand.
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: The inlet strainers may require periodical cleaning. The frequency of this operation is dependent upon installation conditions. The strainer is located in the inlet assembly of the pump casing (Fig. 15) and is removed as follows:a) Isolate pump electrically. b) Release all system pressure.
6.13 No other routine maintenance is required. 6.14 Water scale: As water is heated scale deposits are released in areas of hard water, scale can cause the mechanical seal to stick if left without use for long periods. The pump must be run for at least 5 minutes every four weeks to “exercise” all working parts. Run on cool water. See Section 7 - Technical Specification for note on water temperature. This particularly applies to guest bathrooms used infrequently. 6.

8 TROUBLE SHOOTING GUIDE Symptoms Probable Cause Recommended Action Pump will not start. Insufficient gravity flow. Check flow rate minimum of 0.6 l/min required on full hot and cold. Electrical. 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. Integral motor thermotrip activated.
8.11 Flow Switch Circuit Test: 1. First confirm visually that the flow switch reed clamps have not been dislodged during handling or installation. The clamps must be fully located within their 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.
