6. Remove the V-band clamp from
around the front (input) connector as-
sembly by loosening the 10-32 holding
screw sufficiently to slip the band off.
7. Carefully work the RF section assem-
bly loose and lift it straight out of the
resistor tank.
+
Note: There will be some initial resistance as
the O-Ring seal around the rear connector as-
sembly comes loose from the housing.
As the RF section comes out of the
rear connector assembly, the coolant
will start to pour into the container.
Work the RF section loose slowly, so
that the coolant doesn’t splash.
8. Let the coolant drip for a few minutes
to get as much as possible out of the
radiator tank. As the RF section is
raised out of the radiator tank some
coolant will be trapped in the rear end
cylinder. Turn the section over care-
fully to empty it out.
+
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 col-
lected in the container.
10. Replace the RF section assembly mak-
ing sure that it is smoothly and firmly
seated in the rear connector assembly.
11. Replace the V-band on the front con-
nector plate assembly and tighten 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.
