Servicing The Resistor; Removing The Resistor - BIRD Moduload 8640 Series Operation Manual

Servicing the Resistor

The load is designed to be quickly and easily repaired in the field. If a significant change in the DC resistance is noted
or if the resistor should fail, inexpensive replacement resistors are available.

4. Pull the water chamber assembly out. It may be necessary to rock the chamber gently while pulling.
Note: If the resistor [1] is intact it may be pulled straight out of the load housing and is ready for
replacement. The outer flow tube is captive and will not come out of the housing at this stage.
The ground cap assembly [10] and the inner flow tube [9] should come out with the water chamber assembly. To
remove the ground cap assembly [10], hold the resistor sleeve [7] on the flow tube and pull out the assembly. This
includes the cushioning O-Ring [8] which fits loosely below the stop sleeve; do not lose it.
WARNING
Disconnect the unit from all power sources before servicing.
The unit may be energized from multiple sources.
The potential for electric shock exists.
