INSTALLATION (CONT’D)

GROUNDING INSTRUCTIONS

This product should be connected to a grounded, metallic, permanent wiring system, or an equipment-

grounded terminal or lead on the product.

AIR LINE PIPING

Connection to air system should be of the same size, or larger, than discharge pipe out of unit.  See

recommended piping sizes listed in "Specifications" section.  A union connection to the unit and water drop leg
is recommended.  Install a flexible connector between the discharge of the unit and the plant air piping. Plant air
piping should be periodically inspected for leaks using a soap and water solution for detection on all pipe joints.
 Air leaks waste energy and are expensive.
