Making the Electrical Connections
1. Verify that circuit breaker is properly sized by referring
to heater rating plate. A dedicated circuit breaker
shall be provided.
2. Observe proper wire colors while making electrical
connections. Many electronic controls are polarity
sensitive.
electrical installation are not covered by warranty.
3. Provide overload protection and a disconnect means
for equipment serviceability as required by local and
state code.
4. Conduit shall not be used as the earth ground.
NOTE: A grounding electrode conductor shall be
used to connect the equipment grounding conductors,
the equipment enclosures, and the grounded service
conductor to the grounding electrode.
