Instruction of Use
1. Drilling
Dill the hole about 140mm×3500mm on the earth , or dig the channel about 300mmx3500x800mm and install the grounding rod . Multi grounding rods should be connected by the channel 350mmx600mm.
2. Install the ion grounding rod and connect lead wire;
Remove the seal tape of water absorbing hole and releasing hole (Must );
Put the electrode into assy hole;
Connect the lead wire with anti-corrosion bolt and welded with exothermic welding;
If grounding grid is needed with multi grounding electrodes , 95mm2 copper stranded wire or galvanized round wire or galvanized tape is recommended to connected with exothermic welding.
3. Fix bentonite and water and fill
Fix bentonite and water with the ratio 1:1;
Fill the bentonite and about 50mm higher than electrode , and stir with stick to exhaust the air;
Check the connect the refill the soil ,no stone ,stick or plastic piece left.
4. Test the resistance
Test the resistance 3 days later after installation , and retest one month later and six month later to observe the change.
