CAUTION
Do not block airflow. Air is forced into the housing via fans on all
four sides and exhausts through a grille on the lower rear of the
unit. Blocking air inputs or exhaust could cause unit failure.
CAUTION
Connect interlock before RF operation.
CAUTION
Check the local electrical code for proper AC hookup prior to
operation of the unit. Make sure the neutral or return hookup is
only used for that purpose.
CAUTION
Do not operate without AC power to the load.
CAUTION
Applying more than the rated average RF power to the load may
damage the load resistor.
CAUTION
Do not disconnect AC line power before turning off RF power to the
load. Application of full RF power to the load while the fans are not
running will cause the load to overheat and destroy the resistor
elements.
