  • Page 6 Consideration should be given to upgrading existing ½” (15mm) cold mains pipe- work to a larger size if the recommended minimum pressure/ ow rate is not being achieved. JOULE recommend that primary pipework used has a minimum diameter of 22mm to ensure low pressure loss.
  • Page 7 This water heater must be installed in accordance with this advice to be covered by the Joule warranty. This water heater is manufactured to suit the water conditions of most public reticulated water supplies. However, there are some known water chem- istries which can have detrimental e ects on the water heater and its operation and / or life expectancy.

  • Page 9: General Requirements

    GENERAL REQUIREMENTS SITING THE UNIT This unit can supply outlets above it or at some distance from it but any outlets above the unit will reduce the available outlet pressure by 0.1 bar for every 1m of height di erence. The maximum length of the “dead leg” should be as stated in the Water Supply (Water Fittings) Regulations 1999 G18.7, in particular to the area of most fre- quent use.
  • Page 10 Direct & Indirect Make the connection to the cold feed of the cylinder and incorporate a drain valve. Position the inlet control just ABOVE the Temperature & Pressure Relief Valve (TPRV) mounted on the side of the cylinder. This ensures that the cylinder does not have to be drained down in order to service the inlet control set.

Care must be taken to ensure that the pipework is correctly bracketed, is not in tension or compression, and does not carry the weight of components such as a circulation pump.

The immersion heater must be completely submerged in water with a minimum of 200mm of water above the top of the immersion.
  • Page 17 Install the immersion using rigid cable, 2m long max, with 2.5 mm2 cross-section and a temperature resistance of at least 85°C. The Cable should be rubber insulated HOFR sheathed, complying with BS6141 Table 8. It must be fully earthed. Ensure all terminal connections are securely made. Do not however use excessive force when tightening the terminal screws.
  • Page 18 Disconnect the immersion from the mains electrical supply before removing any covers. Do not attempt to replace the immersion heater(s) with alternatives to those recom- mended by JOULE. Do not bypass the Thermal Cut-Out(s) in any circumstances. REPLACING THE IMMERSION First task is to isolate the power.

  • Page 25: Discharge Agreement

    DISCHARGE AGREEMENT DISCHARGE PIPEWORK The inlet control group should be positioned so that the discharge from both safety valves can be combined via a 15mm end feed Tee, as in the diagram below. Connect the tundish and route the discharge pipe which must be routed in accordance with Building regulation - Part G3 of schedule 1.
  • Page 26 Direct & Indirect EXAMPLES OF ACCEPTABLE DISCHARGEMENT ARRANGEMENTS Ideally below the fixed grating and above the water seal in a trapped gulley. Downward discharges at a low level; i.e. up to 100mm above external surfaces such as car parks, hard standings, grassed areas etc. are acceptable providing that where children play or otherwise come into contact with discharges, a wire cage or similar guard is positioned to prevent contact whilst maintaining visibility.

  • Page 28 Direct & Indirect DISCHARGE ARRANGEMENT FILLING First you must ensure that the pressure in the expansion vessel is the same as the setting of the pressure reducing valve i.e. 3 bar (45PSI). The valve is of the Schrader car tyre type. Check all the connections for water tightness including any factory made connections such as the immersion heater and the temperature and pressure relief valve.

  • Page 29: Maintenance

    MAINTENANCE GENERAL Servicing should only be carried out by competent installers and any spare parts used must be purchased from JOULE. NEVER bypass any safety devices or operate the unit without them being fully operational. DRAINING Switch the electrical power o (important to avoid damage to element). Isolate boil- er from the unit.
  • Page 30 Direct & Indirect YOUR GUARANTEE MAY BE VOID IF YOU CANNOT PRODUCE PROOF OF ANNUAL SERVICING IMMERSION HEATER REPLACEMENT If the thermal cut out on the Immersion heater operates contact a competent install- er. If the thermal cut out fault occurs again the immersion will need to be replaced. Prior to installing the replacement Immersion, ensure the o-ring is correctly posi- tioned on the head of the Immersion and lubricate the threads before tting.
