Be sure that you extend the bare copper wire down all branches of the system. Do not forget to connect the wires to each other with wire nuts when two branches meet at a “Y” or “T” connec- tion.
Ensure that the entire system is grounded. If using plastic blast gates to direct air flow, the ground- ing wire must be jumped (Figure 14) around the blast gate without interruption to the grounding system.

We also recommend wrapping the outside of all plastic ducts with bare copper wire to ground the outside of the system against static electrical build up. Wire connections at Y’s and T’s should be made with wire nuts.
Attach the bare ground wire to each stationary woodworking machine and attach to the dust collector frame with a ground screw as shown in Figure 15. Ensure that each machine is continu- ously grounded to the grounding terminal in your electric service panel.

Ducting Tips
This dust collector is intended for collection from a single machine. It is not designed to draw dust through long runs and multiple ports simultane- ously. We do not recommend using ducting any longer than 10 feet. Otherwise, dust collection efficiency will be greatly reduced. However, still consider these general guidelines for efficient dust collection:
1.Machines that produce the most sawdust should have the shortest run of ducting between the dust collector and the machine. These machines include thickness planers, shapers, sanders, and bandsaws.
2.Ideally, you should design your shop layout so machines will have the shortest possible run to the dust collector.
3.Keep ducting directional changes to a mini- mum. The more directional change fittings you use, the greater the loss of overall pres- sure.
4.Gradual directional changes are more effi- cient than sudden directional changes (i.e. use the largest corner radius possible when changing hose or pipe direction).
5.The simpler the system, the more efficient and less costly it will be.
