Proper Installation of Ground Rod
The rod should not be driven into dry ground. Follow these instructions for proper installation.
1. Dig a hole large enough to hold one to two (2) gallons of water.
2. Fill hole with water.
3. Insert rod through water and “jab” it into the ground.
4. Continue “jabbing” the rod up and down. This allows the water to work its way into the ground,
allowing it to be completely inserted into the ground. This method of installation also assures good
contact with the surrounding soil, thereby making a proper ground.
5. Connect the bare, copper ground wire to the rod with the proper clamp.
6. Connect ground wire to control panel with the ground lug provided in the control box.
7. Ground wire must not have any breaks or splices. Do not use insulated wire for
grounding applications.
Connecting Auxiliary Conveyors
The auxiliary load and auxiliary unload augers or conveyors can be wired directly to the dryer. Electrical
Load Information
on Pages 23-30 shows the maximum horse power and amps of auxiliaries that can be
wired to the dryer. If an auxiliary motor is larger than recommended, it must be powered from a source
outside the dryer and must use a separate contactor and overload protection device for each motor.
However, the operation of the auxiliaries can be performed by the control panel.
