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.
