Electrical Connections
Due to safety none of the Labnics furnaces that use over 16 amps have a plug while
delivery. Main connection of furnace over 16 amps should be managed through a circuit
breaker and according to electrical diagram supplied together with this manual.
Electrical plugs even at low amperes (< 16amps) are prone to create
electrical arcs. We therefore strongly recommend using a circuit
breaker of appropriate amperes rather than the plug.
Any electrical connection to operate this furnace must be done by
a Qualified Electrician .Accordingly any repairs or maintenance
job requires a qualified technician.
The technician who is responsible of commissioning the furnace is
also responsible to act in accordance the rules of safety of European
Community. Technician is solely responsible of selection and use of
appropriate circuit breaker and earth connections.
