CAUTION
Do not install the machine-to-earth grounding rod into dry soil. The soil must be wet
to ensure good contact with the surrounding soil, thereby making an appropriate
ground.
1. Place the machine-to-earth grounding rod within 8 feet (2.4 meters) of the dryer.
2. Dig a hole large enough to hold 2 gallons (7.6 liters) of water.
3. Fill the hole with water and insert the rod through the water and into the ground.
4. Move the rod up and down, working the water into the ground.
The rod is fully inserted into the ground and an appropriate contact with the surrounding soil is
assured.
5. Using an appropriate clamp, connect the bare, copper ground wire to the grounding rod.
6. Connect the ground wire to the control panel using the ground lug that is provided in the control box.
NOTE: Use a minimum grade of number six solid, bare, copper wire. The ground wire must not have
any breaks or splices. Do not use insulated wire for grounding applications.
