Chapter 3: Installation
3-1 Uncrating
2-Pump, 12-Station Controllers 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. 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.
3-2 Mounting the Control Panel
Note: Before you mount the panel, consider how you run wiring to the
vacuum hoppers, the filter chamber atmospheric valve (if so equipped)
and the pump motor starter(s), vacuum switch(es), and vent valve(s).
Mount the panel on a flat, vertical area. It should be a visible area that gives your operator
access to the control. The panel requires a low voltage power drop as listed on the serial tag.
3-3 Electrical Connections
Refer to local electrical codes, the schematic and connection diagrams supplied with this unit
and the serial tag for wiring considerations. Run all wiring in conduit if codes require it.
Making Control Panel Power Drop Wiring Connections
Plug the power cord supplied with your unit into a properly grounded, 3-slot, 115/1/50-60 VAC
or 230/1/50-60 VAC receptacle specified on the control panel serial tag. The control enclosure
draws less than five (5) amps during normal operation at 115/1/50-60 VAC.
Caution! We recommend that you protect PLC memory by providing the control
panel with a dedicated circuit, a true earth ground, and a spike/surge
protector.
