3.3 Electrical
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.
Check that the earth is connected through the PCB
to the chassis with an ohm meter.
Assemble the filter guide provided with the unit, make sure it is locked in position, then put the cover back on.
1. Push the filter guide upwards
2. Rotate anti-clockwise until locked

Installation Procedures
Warning: Do not connect both options. It is essential that the flex and plug cable is removed
