Assembly
RF Connector
Before pushing the RF connector in, be sure that the pro-
jecting center contact pin on the connector is carefully en-
gaged and properly seated in the mating socket of the
load resistor input.

screws into the corners of the RF connector.
Diaphragm and
Coolant Oil
To assemble, follow the instructions below.
1. Fill the unit with coolant until the level is about
one inch (25.4 mm) below the top of the radiator
cylinder.
2. Install the diaphragm and place the diaphragm
cover on the back end of the radiator tank.
3. Install and tighten the clamping band screw.
4. Check for leaks. Pay particularly close attention
to the area around the clamping band.
