4.4.1 Disconnect
A properly sized, separate, lockout type disconnect for each fan should be mounted on the main power panel,
especially if the fan unit is not entirely visible from the main power panel.
Note
For fans and heaters installed in Canada:
Electric disconnect switch having adequate ampacity (see
marking on the dryer for voltage and ampacity). If not provided as part of the dryer, shall be installed in
accordance with the Canadian Electric Code, Part I, CSA C22.1.
4.4.2 Grounding
• AGI recommends that fan and heater be connected to a ground rod that is no further than 8 feet away.
• The ground rod should be connected with a minimum 6 AWG solid, bare copper wire.
• The ground rod must be copper-clad and 5/8" diameter x 8 feet long.
• Install the rod 2 feet away from the fan/heater and/or bin foundation.
• Make certain to follow all local regulations.
Important
The ground rod-to-fan or bin connection provides additional safety in the event of a short or lightning
strike. It also provides the necessary grounding for operation and helps provide for a long life of control
circuits.
AGI does not supply or sell ground rods and wires. Please contact your local electrical parts supplier. AGI
recommends that the rod not be driven into dry ground.
Typical Ground Rod Installation
The following is considered to be reference only for a typical ground rod installation:
1. Dig a ditch large enough to hold 1 to 2 gallons of water.
2. Fill the ditch with water.
3. Push the rod into the water and jab it into the ground repeatedly, to allow the water to work its way into
the hole. Drive the rod completely into the ground.
4. Connect one end of the ground wire to the rod with an appropriate ground clamp.
5. Connect the other end of the wire to a ground lug connector inside the fan control box. The ground wire
should not have any splices or breaks. Insulated wire is not recommended for grounding purposes.
