  • Page 42: Connections – Plumbing

    CONNECTIONS – PLUMBING RELIEF VALVE DRAIN DN15 copper drain lines must be fitted to the temperature pressure relief valve and expansion control valve (if one is installed). Connect the drain lines to the valves using disconnection unions. The drain line from the valve to the point of discharge should be as short as possible, have a continuous fall all the way from the water heater to the discharge outlet and have no tap, valves or other restrictions in the pipe work.
  • Page 43 CONNECTIONS – ELECTRICAL The power supply to the water heater must not be switched on until the water heater is filled with water and a satisfactory megger reading is obtained. All electrical work and permanent wiring must be carried out by a qualified person and in accordance with the Wiring Rules AS/NZS 3000 and all local codes and regulatory authority requirements.
  • Page 44 CONNECTIONS – ELECTRICAL THERMOSTAT SETTING The thermostat is adjustable from 60°C to 70°C. The thermostat is adjusted by turning the adjuster anticlockwise to decrease the temperature setting and clockwise to increase the temperature setting. Only adjust the temperature setting when the isolating switch is switched off at the switchboard. For reasons of safety and economy, we advise the thermostat be set at the lowest temperature that will provide sufficient hot water during periods when boosting is required.
