8. Electrical installation WARNING: THIS EQUIPMENT MUST BE EARTHED. All electrical wiring must be carried out by a competent person and in accordance with the current I.E.E. Wiring Regulations. The control equipment supplied will ensure that the cylinder functions safely. It is intended that these controls operate in conjunction with other control packages as described in the Solar system installation guide which incorporates a programmable time clock etc.
8.3 Two Port Valve-The two port valve should be wired to the twin thermostat as per Figure 8.2 below: 8.3.1 Connect the Live supply to the thermal-cut-out and connect the brown wire of the two-port valve to terminal 2 on the thermostat. Earth and Neutral supplies can be connected directly to the valve.
10.4. Only use spare parts authorised by Dimplex. The use of other parts will invalidate the warranty. 10.5. Draining the Cylinder - Having isolated the electricity supply, drain the cylinder. When draining the cylinder, always switch off the solar system and the immersion heater first.
10.9. In hard water areas it may be necessary to remove and de-scale the immersion heater element. Replace the gasket each time it is removed. If large amounts of scale is present it may be advisable to fit a water softening device. 10.10.
12.5. WARNING: If cold/warm water exits from the temperature and pressure relief valve (TPV) or from the pressure relief valve call your installer or the Dimplex customer service centre. If very hot water exits from either valve switch off the heat source immediately and isolate the electricity supply to the cylinder and separate heat source.
