    Tundish. The Electrastream must have a dedicated 40 amp MCB. The Electrastream must be wired through a 40A class A, double pole isolating switch with at least 3mm pole separation, this switch should also have both electric and mechanical indicators. The switch should be located near to the Electrastream control unit.
  • Page 32 4-2.6 Tri-core Heater The H1, H2 and H3 connections on the Electrastream control unit can be connected to any of the three heater elements, however each element MUST be wired independently with a separate 3 core 2.5mm² heat resistant cable.

    The unit consists of a temperature sensor and over temperature cut-out device, both are TWIN COIL CYLINDER wired back to the Electrastream control unit - see wiring diagrams figs. 3-3a and 3-3b. The box must be fitted to the cylinder with its phial and sensor inserted into the socket provided (located above the tri-core heater).
  • Page 34 The accumulator should be installed vertically. The floor must give adequate support to the filled accumulator. Note As Electrastream Plus is a sealed system, Accumulators must have frost protection when they are installed where low temperatures the pressure at the taps is not affected by could be a potential problem - see 1-4.7.
