Installation must comply with the relevant local and/or national regulations. Ensure that there is a
correct connection group with a mains fuse. The electrical diagram is displayed on the appliance. A
basic diagram for the GS+ appliance can be found in chapter 8 and 9 Electrical diagrams. In the case
of the G+ with a centrifugal fan, please refer to the diagram on the appliance.
PLEASE NOTE:
– The appliance must be adequately earthed. The appliance must be fitted with an isolator switch
which interrupts phase and zero (not earth).
– The isolator switch must be accessible at all times.
– Never, under any circumstances, allow the supply to the appliance to be interrupted by other
switches. This could result in the appliance overheating.
– The unit is phase sensitive.
2.5 Siphon [1]
