  • Page 8: Water Supply

    Water Chemistry This water heater must be installed in accordance with this advice to be covered by the Joule war- ranty. This water heater is manufactured to suit the water conditions of most public reticulated water supplies. However, there are some known water chemistries which can have detrimental effects on the water heater and its operation and/or life expectancy.
  • Page 9 Some water analysis reports may state the conductivity of the water rather than the level of total dis- solved solids. Conductivity, measured in microsiemens per centimetre (μS/cm), is directly proportional to the TDS content of the water. TDS, in mg/L, is approximately 70% of the conductivity in μS/cm. The JOULE warranty will not cover resultant faults to the storage cylinder if this water heater is con- nected at anytime to a water supply where the TDS content of the water exceeds 600 mg/L. 16 In locations where TDS approaches 600 mg/L, e.g. due to sediment, we strongly recommend fitting an appropriate filter to ensure water entering or in the water heater does not exceed this level at any time i.e.

    Cold Mains Pipework Run the cold main through the building to the place where is to be installed. Take care not to run the cold pipe near hot water or heating pipe work so that the heat pick-up is minimized. Identify the cold water supply pipe and fit an isolating valve (not supplied). A 22mm BS1010 stopcock can typically be used but a 22mm quarter turn full bore valve would be better as it does not restrict the flow as much. Do not use “screwdriver slot” or similar valves. Make the connection to the cold feed of the cylinder and incorporate a drain valve. Position the above inlet control just the Temperature &...

It should be noted that the use of a secondary circulation circuit can increase running costs as there will be circulation pipe losses.

  • Page 13 Dead Legs The length of hot water draw off to taps and other outlets should be kept to a minimum to reduce the amount of cold water drawn off before the hot water arrives. The maximum recommended dead leg lengths are shown in figure 2.b. Where there is more than one size of pipe on a dead leg, the equiva- lent length and size should be estimated.Where the dead leg length exceeds the recommended maximum, secondary circulation should be installed. It should be controlled by a time switch and incorporate a motorized valve that can prevent gravity circulation in the circuit.

The immersion heater must be completely submerged in water with a minimum of 200mm of water above the top of the immersion.

  • Page 28: Immersion Testing

    Ensure all terminal connections are properly tightened prior to commissioning For installations with high water demands, or areas with hard water, Titanium immersions should be fitted. The thermostat should be set so that the water is heated to a temperature between 60°C and 65°C. Water stored at temperatures below 60°C can result in bacteria growth and temperatures above 65°C can cause scalding. The immersion stat has an integrated high limit stat which If the primary thermostat fails the limit thermostat takes over and shuts the element off before the water can boil in the cylinder. www.jouleuk.co.uk | www.joule.ie...
  • Page 29 If the water is getting extremely hot the the thermostat is stuck in the ‘ON’ position and will need to be replaced. Safety • 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 recommended by JOULE. • Do not bypass the Thermal Cut-Out(s) in any circumstances. Replacing The Immersion First task is to isolate the power. Immersion heaters are rated at 3kW and require their own 20A double pole isolation switch. Turn off the power from the isolation switch and remove the fuse. Next turn off the water to the tank. Drain the water from the tank via the drain cock using a hose. Remove the immersion using an immersion spanner.

    Discharge Arrangement 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 dis- charge pipe which must be routed in accordance with Building regulation - Part G3 of schedule 1. When operating normally water will not be discharged. Water discharge from the two safety valves will only occur under fault conditions.

    Ensure the lever on the two port valve is set to the filling position. When full, move the lever back. Switch the programmer to Domestic Hot Water (DHW) and allow the unit to start to heat. Adjust the dial of the dual thermostat to between 30°C and 70°C as required. Storage Temperature 60-65°C is the recommended storage temperature for both direct and indirect cylinders. In hard water areas consideration should be given to reducing this to 50-55°C. In many healthcare appli- cations the guidance on Legionella control and safe water delivery temperatures will require storing the water at 60-65°C, distributing at 50- 55°C and using thermostatic mixing valves to control the nal temperature. For details consult the NHS Estates Guidance on safe hot water temperatures. www.jouleuk.co.uk | www.joule.ie...

  • Page 47: Annual 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 off (important to avoid damage to element). Isolate boiler from the unit. Turn off the cold water supply valve. Open hot water tap. Open the drain valve. The unit will drain. Water drained off may be very hot! Annual Maintenance The water heaters require annual servicing in order to ensure safe working and optimum perfor- mance.
  • Page 48 Inspection Where internal inspection of the cylinder is required an endoscope can be used. Inspection can be carried out by draining down the cylinder and removing a component that is fitted to a wet connec- tion in the cylinder. Safety Valve Checks rom either the temperature/pressure relief valve or the expansion relief valve indicates a problem. • Check your discharge pipework is free from debris and is carrying water away to waste effec- tively. • Next hold both of these safety valves open, allowing as much water as possible to flow through the tundish. • Release the valves and check that they reseat correctly. Completion of the Benchmark Checklist on pages 52-53 must be adhered to by the installer www.jouleuk.co.uk | www.joule.ie...

  • Page 49: Shutting Down

    Taking The Cylinder Out Of Use Shutting Down • Ensure the cold water supply is isolated and at least two hot water draw off points are open prior to draining the cylinder. • One of the hot water draw off points should be as close as possible to the height of cylinder in draw off terms. • Where applicable use the drain valve at the cold water inlet to drain the contents of the cylinder. • Isolate the coil from the main heating system. If necessary blow out the coil prior to moving the cylinder. Recycling And Disposal The cylinder or any of its components must not be disposed of in domestic rubbish. The material in the cylinder, packaging and components contain recyclable materials and they should be disposed of properly and in accordance with national regulations.
