Electrical Information

The Coldbuster heater element has been classified as an electrical appliance. You must engage a

licensed electrician for the heater installation if this is required by your state regulations.

However, all electrical connections, including setting up the conduits (more detail below) and the

connection of the thermostat must be undertaken by a licensed electrician in accordance with

current electrical codes of practice, AS/NZS3000: 2007 and state codes.

1. The heater element must be connected to

a circuit with RCD protection.

2. Consult with your electrician to ensure any

existing cabling and RCD already installed

are working and capable of handling the

additional load.

on size of conduit

the heater runs
