Operating Instructions
General
The Models 8745/46 Termaline Load Resistors do not have any operating con-
trols. Therefore, the presence of operating personnel is not required when in
use. Proper operation of the equipment is assured if the instructions contained
in "Installation" on page 5 are followed exactly.
Do not apply more than the rated RF power to the load. The water flow rates
and inlet water temperature, +5°C to 60°C (+41°F to +140°F), must be as spec-
ified in the following table.
In actuality, an adequate and uninterrupted flow of water is more critical
than the actual water temperature.
Operation as a Load Resistor
1. Turn on the AC power (if the load is equipped with an interlock system).
2. Turn on the water supply.
3. Check for proper interlock operation.
4. Check that all coaxial power line connections are properly tightened.
5. Apply RF power to the load.
6. Proceed according to instructions pertaining to the specific transmitting
equipment.
CAUTION
DO NOT disconnect the water flow switch leads from the control assembly.
Any operation of the load without a properly functioning cooling system will
cause almost immediate destruction of the resistor element.
WARNING
Never attempt to disconnect the equipment from the transmission line while
RF power is being applied. Leaking RF energy is a potential health hazard.
