
Undersized pipe or poor routing of pipe will degrade the performance of the compressor package. Inspect
all connections to insure they are tight, sealed, and secured.

A shut-off valve must be installed at the package discharge to insure that the compressor package can be
isolated from the system air pressure for safe maintenance of the equipment. You cannot rely on a check
valve to provide safe isolation of the compressor package.

A check valve in the air piping from the compressor can interfere with the proper operation of the
compressor controls.

Compressor package metal or nylon tubing must be checked. Visually inspect these tubes located in the
compressor package.

Tubes can come loose or get damaged in shipping so look for loose or damaged tubes. Verify the
flexibility of the nylon tubes while inspecting for any damage.

Verify that all tubes are secure in their tube fittings to insure that none of the tubing might leak at or come
loose from there fittings when the compressor is in operation. Damaged or loose tubes can result in
lubricant being sprayed on hot surfaces when the compressor is in operation and result in damage to the
compressor or a fire.

After the installed compressor package has been inspected you can restore power to the package. With
the proper power applied to the package you can verify proper rotation of the compressor and the cooling
fan.
4.3 BADGERXE NEMA 4 VFD Option Installation
The supply power to the package must use liquid tight conduit and liquid tight conduit fittings to maintain the
NEMA 4 rating. Compressed Air, with a minimum pressure of 100 PSIG, should be supplied to the package fitting
connected to the vortex cooling system. The ISO standard for this air supply is ISO 8573-1:2010 Class 2.4.2.
If installing outdoors, consideration must be given to exposure to the sun. The electrical enclosure door (end of
package) should be located out of direct sunlight (North or South). The intent would be to minimize the amount of
cubicle surface area exposed to direct sunlight.
