Final Steps
Plug the control cable from the iVAC Contactor into the outlet on the front of the iVAC Switch. Plug the
iVAC Switch into a wall outlet. If your Pro Switch is a 20 amp model and your outlet is for 15 amps, use
the adapter cable that comes with the Pro Switch to make the connection.
Set the dust collector’s power switch to ON. If your dust collector has a magnetic switch, press the
green or START button on the magnetic switch or use the dust collector’s remote control to turn it on.
You will not have to do this again until you press the Red or Stop button or there is a power failure.
Set the mode switch on the front of the iVAC Switch to ON and the dust collector should start. If it does
not, check the circuit breaker for the dust collector circuit in your distribution panel and your wiring.
You can plug a light or small power tool into the Pro Switch to make sure it is working. If neither of
these is the source of the trouble, double check your wiring. If you can hear the contactor make a big
“clunk” noise when you turn the iVAC Switch on or off then the iVAC Switch and the contactor are both
working. If the dust collector started when you set the mode switch on the iVAC Switch to ON, then set
the mode switch to OFF to stop the dust collector. Then set the mode switch to AUTO to allow the iVAC
System to control your dust collector automatically.
Using the iVAC Contactor with an iVAC Switch Box (model SB-NA)
Install the iVAC Contactor with your dust collector, using the instructions above for dust collectors with
or without a magnetic switch as appropriate.
Mount the iVAC Switch Box where you want it and plug the Tool Input cord (the long one) into a working
115 volt outlet. Plug the Vacuum Power input cord (the short one) into the Auxiliary socket on the
Switch Box. Plug the control cable from the contactor into the Vacuum Power socket on the Switch Box.
Plug your power tool into the Tool Power outlet on the Switch Box.
Turn your dust collector power switch to the ON position.
Move the mode Switch on the Switch Box to ON. The contactor should make a big “clunk” noise and the
dust collector should start. When you move the mode switch to OFF the contactor will make the “clunk”
noise again and the dust collector will shut off. Move the mode switch to the Auto position and the
Switch Box will start and stop your dust collector automatically when you turn the power tool plugged
into the Tool Power outlet on and off.
