  • Page 12: Installation Guidance

    Installation Guidance Installation should only be carried out by a “competent operative” i.e. the installer must have attended a recognised course in unvented hot water systems. All registered operatives should carry an Identification Card issued by the institute of Unvented Hot Water Systems. The installation area should be able to cope with the weight, incoming pipes and discharge pipe when full.

    Installation Guidance (continued) 5. The TPRV (temperature and pressure relief valve) is set at 90°C and 7 BAR. No valves should be fitted between the relief valves and the cylinder. 6. The tundish, which shows visible discharge from the relief valves, is to be in a prominent, visible and safe position away from any electrical devices .

  • Page 15: Discharge Information

    Discharge Information Discharge pipes from safety devices D3.50 Safety devices such as temperature relief valves or combined temperature and pressure relief valves should discharge either directly or by way of a manifold via a short length of metal pipe (D1) to a tundish. 3.51 The diameter of discharge pipe (D1) should be not less than the nominal outlet size of the safety device, e.g.

    Discharge Information (continued) 3.57 The discharge pipe (D2) should be made of: a. metal; or b. other material that has been demonstrated to be capable of safely withstanding temperatures of the water discharged and is clearly and permanently marked to identify the product and performance standard (e.g.
  • Page 17 Discharge Information (continued) If plastic pipes are used as branch pipes carrying discharge from a safety device, they should be either polybutylene (PB) or crosslinked polyethylene (PE-X) complying with national standards such as Class S of BS 7291-2:2006 or Class S of BS7291-3:2000 respectively; and d.
  • Page 18: Commissioning

    Commissioning IMPORTANT 1. Ensure the drain at the base of the cylinder is closed. 2. Open a hot tap the furthest distance from the unit. 3. Gradually open the cold mains isolator valve and fill cylinder until water appears at the hot tap. Attend to each hot water outlet in turn and ensure water flow is obtained at each outlet expelling any air within the pipework.

  • Page 21: Troubleshooting

    Troubleshooting DISCHARGE FROM EITHER OF THE RELIEF VALVES INDICATES A MALFUNCTION IN THE SYSTEM AND MUST BE INVESTIGATED IMMEDIATELY. OVERHEATED HOT WATER DISCHARGE In the unlikely event of overheated (95°C) water being discharged, the heat source(s) should be switched off immediately and a competent operative called out.
  • Page 22: Troubleshooting (Continued)

    Troubleshooting (continued) 3. If the gauge shows a pressure in excess of 3 BAR, the pressure reducing valve (if adjustable) may be set too high, or may have developed a fault. If adjustment of the valve doesn’t bring the pressure down to 3 BAR (after opening and re-closing a tap), it should be replaced.
  • Page 23 Troubleshooting (continued) IMMERSION HEATERS If the immersion heater is not heating the water, the electrical cut- out (or high limit stat) may have operated. This may be due to the control stat being set too high, being miscalibrated, or having developed another fault.
  • Page 24: Servicing

    Servicing Annual maintenance and servicing should be carried out by a competent operative. Failure to maintain this system in accordance with these instructions will invalidate the manufacturer’s warranty. We would, therefore, recommend that a regular service schedule is arranged at the time of its installation. All maintenance and servicing work should be recorded on the next page of this booklet.
