• On VTPB pumps, wire the pump package blowback solenoid
( SOL B ) to the terminal located in the VacTrac control panel
enclosure.
• On 115 VAC control voltage systems, run a common hot
115 VAC wire and a common neutral wire from the
controller to the pump package in the VacTrac system.
• On 24 VDC control voltage systems, run a common +24
VDC wire and a common 0 (zero) VDC wire from the
controller to the pump package in the VacTrac system.
Notes: • Make sure that the pump motor starter, the vacuum relief
valve solenoid, and the blowback solenoid (if
supplied) are the same voltage (24 VDC or 115 VAC)
as the VacTrac control panel control voltage. Consult
the control panel serial tag and the pump package
serial tag.
• Wire size depends on control voltage, distance, number
of vacuum hoppers, and the number of wires in each
raceway. Consult a qualified electrician.
