Resistor Removal
Numbers in brackets [ ] refer to the labeled parts in Figure 7. Parts
may appear slightly different than what is shown for some models.
1. Disconnect the load from the RF line and the interlock control box,
remove the water hoses, and drain off any water still in the load.
2. Turn the load on end with the hose fittings up.
3. Remove the screws [4] from the back of the water chamber
assembly [3]. These secure the water chamber assembly to
the load housing [0].
NOTE: The 8731 has only one screw, on the side of the water
chamber assembly. Also, the water chamber is threaded, and
screws into place. Turn the water chamber counterclockwise until
the threads disengage before pulling the assembly out.
4. Pull the water chamber assembly out. It may be necessary to rock
the chamber gently while pulling.
5. If the resistor is intact then the entire resistor assembly [2] may
be pulled straight out of the load housing.
Inspection
When the resistor has been successfully removed, inspect it carefully
to insure that it has not been fractured. In most cases, even in the
event of complete resistor burnout the resistor will remain intact.
Examine the inside of the load housing and water chamber for damage
to internal parts, especially the resistor O-Ring seal and the resistor
contact strip. If the O-Ring has cracks or if the contact strip has
missing fingers, replace them. If the resistor did fracture, thoroughly
rinse all parts under clear running water and dry before any assembly.
Resistor
Replacement
1. Insert the plugged end of the new resistor into the resistor fitting
of the center conductor assembly [8] to test its tightness.
2. The resistor should be snug but should not have to be forced into
the fitting. If the resistor is too loose, press the fitting fingers
together slightly and try the resistor again. Continue closing the
ends of the resistor fitting until a snug fit is obtained.
WARNING
If the resistor breaks, there may be splinters or sharp pieces inside
the load housing. Be careful when repairing to avoid being cut.
CAUTION
Do not remove the resistor plug. Any attempt to do so will cause
leakage and resistor damage.
