Proper Installation of the Ground Rod
(Ground rods and wires are not supplied by GSI.) It is recommended that the rod not be driven into dry
ground. The following steps ensure proper ground rod installation:
1. Dig a hole large enough to hold 1 to 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, the water will work its way down the hole, making it possible
to work the rod completely into the ground. This method of installing the rod gives a good conductive
bond with the surrounding soil.
5. Connect the bare copper ground wire to the rod with the proper ground rod clamp.
6. Connect the bare ground wire to the fan control boxes with a grounding lug. (See Figure 5A
on Page 13.)
7. Ground wire must not have any breaks or splices. Insulated wire is not recommended for grounding.
