Caution Statements

The following equipment cautions appear in the text whenever the 

equipment is in danger of damage and are shown here for emphasis.

CAUTION

Incorrect hose connections will reverse coolant flow and

could destroy the load.

CAUTION

Different control systems are used for 115 Vac and 230 Vac. Use the 

correct interlock control for your voltage.

CAUTION

If installed, connect optional interlock before applying RF power.

CAUTION

Do not interrupt coolant supply. Even momentary

application of RF power while coolant is not circulating could

cause immediate destruction of the load

CAUTION

Do not remove the resistor plug. Any attempt to do so will cause 

leakage and resistor damage.
