DS7420 

 

NOTE 

A 15amp, 120 volt circuit is required.  A dedicated circuit is preferred but not essential in 
all cases.  A dedicated circuit will be required if, after installation, the circuit breaker trips 
or fuse blows on a regular basis when the heater is operating.  Additional appliances on 
the same circuit may exceed the current rating of the circuit breaker. 

 

 

WARNING 

Ensure the power cord is not installed so that it is pinched or against a sharp edge and 
ensure that the power cord is stored or secured to avoid tripping or snagging to reduce 
the risk of fire, electric shock or injury to persons.

 

Construction and electrical outlet wiring must comply with local building codes and other 
applicable regulations to reduce the risk of fire, electric shock and injury to persons.

 

Do not attempt to wire your own new outlets or circuits.  To reduce the risk of fire, 
electric shock or injury to persons, always use a licensed electrician.
