Installation Procedures
This unit is designed for connection to a 220-240 volt AC
power supply via either a concealed electrical connection or
an exposed electrical connection.
For an exposed electrical connection, the pre-fitted flex
and plug cable is plugged into the PCB as shown. Use a
standard 10 amp, 220-240 volt power outlet within 1500
mm from the heater with adequate power for the unit.
For a concealed electrical connection, disconnect the
pre-fitted flex and plug cable at the PCB connector and
discard. Connect the Live (Active) and Neutral wires of the
concealed power cable through the rear access opening to
the green terminal block on the PCB. Crimp a 6.3 mm QC
female spade connector to the earth wire of the concealed
power cable and attach to the chassis earth male terminal.
For a concealed electrical connection, an isolation switch
should be installed.
Check that the earth is connected through the PCB to the
chassis with an ohm meter.
2. Rotate clockwise until locked
Thread Tape
2. Before installing the tap, ensure sufficient
thread tape is applied to the thread.
