Caution Statements
The following equipment cautions appear in the text whenever the equipment is in danger of damage and are
repeated here for emphasis.
CAUTION
See page 4.
The water flow must be kept in the proper direction; incorrect flow will cause almost
immediate burnout.
CAUTION
Do not apply more than rated RF power to the load. The water flow rate and inlet
temp. (5° C to 60° C) must be as specified:
Model
8792
Power
80 kW
5° C
9 gpm (34 lpm)
60° C
12 gpm (45.4 lpm)
Adequate and uninterrupted full water flow is more critical than temperature.
CAUTION
Verify cooling liquid is flowing through the load before RF power is applied and ensure
the cooling liquid supply is not interrupted while load is in operation. Even momentary
interruption of coolant supply while RF power is applied will cause almost immediate
burnout.
CAUTION
Never reverse the cooling water connections. It is very important for the safety of the
load resistor to observe proper flow direction. Also, when the load is first installed or is
reconnected, run the water for approximately one minute to fill the system and
remove all air pockets before applying RF power.
CAUTION
Do not use any pliers or wrenches on the resistor fitting [22] as damage to its surface may
result.
