3-1 Uncrating the Equipment
The mechanical components of the conveying system are shipped mounted on a skid,
enclosed in a plastic wrapper, and contained in a cardboard box.
1. Pry the crating away from the skid.
Note: Remove the nails holding the box to the skid and lift the box off carefully;
avoiding staples in the 1’ x 4’ wood supports. Cut the steel banding.
2. Use a pry bar to remove the blocks securing the unit to the skid.
3. Lift unit from sides, inserting forklift under the base. The forks must be
equidistant from the centerline of the unit and the unit must be balanced
on the forks. Lift slowly and only high enough to clear the skid. Use a
pry bar if necessary to carefully remove the skid from the unit.
4. Lower slowly.
5. Temporary hardware has been installed to prevent side panels from
shifting in transit. Remove hardware.
6. Retain the crating material for reshipping the components in case hidden
shipping damage is found.
3-2 Rigging and Placing Mechanical Components
Conveying system installations vary depending on the application: in-plant distribution or rail
car unloading, single or multiple material line systems, pellets, or powders. The sections on
the following pages are general installation guidelines.
Installing the Pump Package
Place the vacuum pump where you can have easy access to the 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.
Vacuum Pump Vent Piping Considerations
Most 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.
Note: Improper sizing or ducting of exhaust air voids your warranty!
