Note: An alternate, but much slower, method of draining the radiator would be
to siphon the coolant out of the thermoswitch hole.
9. Discard the contaminated coolant collected in the container.
10. Replace the RF section assembly making sure that it is smoothly and firmly
seated in the rear connector assembly.
11.Replace the V-band on the front connector plate assembly and tighten the
the screw.
12.Add clean coolant to the unit. Fill the unit until the level is about
3-1/4 inches below the thermoswitch hole.
13.Coat the pipe plug or thermoswitch threads sparingly with pipe
sealant. Do not contaminate the coolant.
14.Screw the pipe plug or thermoswitch back in place carefully to avoid
stripping the aluminum threads of the plug hole.
15.Lower the attenuator back onto its feet.
16.Check all seals for signs of leaks.
RF Load Resistor
To replace the load resistor follow the same procedure as in the Replacing Coolant
section. However, inspect the O-Ring seals. Do not reuse the O-Rings if they are no
longer soft and pliable or shows signs of cracks. If the coolant removed is not
contaminated, it may be reused in the radiator tank with additional new coolant as
required. The RF section is not field repairable and further disassembly should not
be attempted. Return the entire RF assembly to the factory for repair or replacement.
Thermoswitch
To remove or replace the thermoswitch use the procedures in the Thermoswitch
paragraph in Chapter 3 - Installation.
Repairs
Any maintenance or service procedure beyond the scope of those provided in this
