Resistor Servicing
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.

Numbers in brackets [ ] refer to the labeled parts in Figure 9.
1. Disconnect the load (see “Load Removal” on page 18).
2. Turn the load on end with the hose fitting up.
WARNING
Disconnect the unit from all power sources before servicing.
The unit may be energized from multiple sources.
The potential for electric shock exists.
