Maintenance

4. Remove the following parts and set them aside for reassembly:
z Inner flow tube [9]
z Resistor sleeve [7]
z Cushioning O-ring [8]
5. Remove the ground cap assembly by gently prying it upward using the flat
blade of a screw driver and working around the circumference of the part
until is is free.
 Note: The ground cap assembly [10] should now be exposed on the
resistor at the end of the load housing.
6. Pull the resistor [1] straight out using a gentle rocking motion.
 Note: Do this only if the resistor [1] is intact.
 Note: The resistor sleeve [7] has a small escape hole at the side and
an access counter bore leading to it. If the sleeve is removed, be sure
this counterbore faces the O-Ring and the resistor [1] during reassem-
bly. This is essential for internal water venting. The base of the inner
flow tube has water outlet holes and a small shoulder. At reassembly,
these must fit into mating recesses in the input fitting.
Inspecting the Resistor
1. Carefully check the resistor [1] for fractures.
 Note: Even in the event of failure the resistor substrate will usu-
ally remain intact.
2. Check the inside of the housing for damage to the internal parts.
3. Do one of the following:
z If the resistor is broken, other internal parts are damaged, or if the
parts do not fit together properly, proceed to "Replacing a Fractured
Resistor" on page 23.
z If no damage has been found, proceed to "Replacing the Resistor" on
page 24.
Replacing a Fractured Resistor
1. Turn the assembly on end with the RF input connector up to allow any
loose pieces of the resistor to fall out of the housing.
2. Use a
3
⁄
16
hex socket wrench to remove the cap screws [16].
3. Remove the outer conductor assembly [12].
4. Pull out the center conductor assembly [11].
5. Remove, carefully, any remaining pieces of the resistor.
 Note: Normally the outer flow tube will remain with the housing.
If it comes out, return it after inspection and cleaning.
6. Check the inside of the housing for damage.
7. Remove the inner flow tube [9] and ground cap assembly [10].
8. Check inner flow tube and ground cap assembly for broken pieces.
9. Wash, thoroughly, the inside of the conductor assemblies, housing and
water chamber under clear running water.
10. Replace the ground cap assembly and the inner flow tube.
