3-4 Installing the VacTrac Pump Package
Place the vacuum pump where you can have easy access to
mechanical components. Choose a clean, dry place where debris
won’t be drawn into the vent valve on top of the blower. If you
install the unit outside, you must provide a weather shed to shelter
the unit.
1. Level the vacuum pump package. Use shims as needed.
2. Secure the vacuum pump package with appropriately-sized
bolts to the floor or mounting platform.
3. Do not twist or warp the pump package base. This can
misalign the blower housing and damage the blower.
VacTrac Vacuum Pump Vent Piping Considerations
Most AEC VacTrac vacuum pumps are installed with no exhaust
venting of the vacuum pump discharge. If your installation requires
vacuum pump exhaust venting, follow these guidelines:
• Venting exhaust air from vacuum pumps requires the
installation of metal pipe or ducting. Make sure that no more
than two inches water column (2” WC or about 0.5 kPa)
back pressure is present at the discharge of the vacuum
pump silencer.
Important!
Improper sizing or ducting of exhaust air voids your AEC warranty!
• Use piping or ducting at least two (2) sizes larger than the
vacuum connection. Overall vent pipe length—horizontal
plus vertical—should not exceed 100 feet (about 30 m) and
should not include more than three (3) elbows. If you use
pipe for venting, make sure that you use Sch. 5 or Sch. 10
pipe with long radius elbows to provide minimum airflow
resistance. If you use ducting, make sure you use high-
pressure ducting with mitered bends—with a minimum of
three (3) breaks—for minimum airflow resistance. Make
sure all piping connections are properly supported.
