MAINS TERMINALS
CONNECTING THE MAINS CABLE - Connect the restricted (E7)
supply to the terminal block, marked “Storage Circuit”, having
first passed the cable through a front cable clamp in the base. Connect the
unrestricted (Peak) supply to the terminal block, marked “Fan/Boost Circuit”,
having passed this cable through another cable clamp in the base.
At this point, if desired, an external fan/boost timer may be fitted to the
heater by passing the two wires from the timer through the remaining cable
clamp, and connecting them across the terminal block, marked “Timer”,
having already removed the link fitted across this block at the factory.
Connect the EARTH lead from both supplies to the terminal marked with
the symbol.
