Field Wiring
Complete the electrical wiring in accordance with local and National Electrical Codes. The ground wire should be secure under the green
screw. Check all screws for tightness. If the installation is in a hazardous area, all electrical leads must be sealed with an approved com-
pound, in accordance with local and National Electrical Codes unless the switches are hermetically sealed. (NEC 5051-5)
Always check the nameplate to make sure the approval ratings coincide with the application.
CAUTION: To prevent ignition of hazardous atmospheres, replace cover before
connecting
the electrical circuits.
Keep cover tightly closed when in operation.

(Air Line) Installation Considerations
Air Mains and lines should be large enough to avoid excessive pressure loss under conditions of maximum flow. Air lines should be
installed with as few restrictions as possible if the cost of compressed air is to be kept to a minimum. Sharp turns in piping should be
avoided for more effecient air flow and economical air power. It is advisable to pitch the mains in the direction of air flow so that both grav-
ity and air flow will carry the water to traps or water legs located at frequent intervals.
To help in preventing condensed moisture from reaching the point of usage, down pipes should never be taken directly from the bottom
of air pipes or mains. Connection should be made at the top of the main and a long radius return bend used
.
