[. . . ] Isolation should preferably be by a double pole switched fused spur box having a minimum contact separation of 3mm on each pole. The fused spur box should be readily accessible and preferably adjacent to the boiler. A fused three pin plug and shuttered socket outlet may be used instead of a fused spur box provided that: a) They are not used in a room containing a fixed bath or shower. b) Both the plug and socket comply with the current issue of BS1363. The mains electrical supply must be maintained at all times in order to provide domestic hot water. To gain access to the connection box remove the two retaining screws indicated in Diagram 9. 1 and carefully lower and pull forward the box to reveal the terminal strip inside. Remove the test cable from the terminal strip and discard. Connect both the mains supply and switched live from the external controls (room thermostat and, if applicable, frost thermostat) into the marked terminals as shown in diagrams 9. 2 and 9. 3. If a room thermostat is not fitted, then the connecting link must be fitted between terminals 1 and 2, see diagram 12. 2. Connect the pump supply into the marked pump terminals as shown in diagram 9. 2. Observe all terminal markings and colour codes as shown in diagram 12. 2. NOTE: The boiler incorporates a pump overrun thermostat. Only feed the pump from the marked terminals in the connection box on the boiler, not from a separate supply. Ensure that all flexible cords are routed through the strain relief cable glands on the inlet of the connection box. Refit the connection box to the underside of the boiler using the two retaining screws. RETAINING SCREWS (2) 9. 1 External controls (Mains Voltage) Important: If a replacement supply cable is required it must be purchased.
