MOUNTING _________________________________________

•WARNING Remove the unit from the skid before mounting.

Typical Remote Air Inlet Piping.

ELECTRIC MOTOR UNITS. Bolt the unit to a firm, level foundation (such as a concrete floor). Do not bolt uneven feet tightly to the foundation, as this will cause excessive stress on the receiver tank. Use metal shims under the “short” feet if necessary.

under the “short” feet if necessary. Gasoline engine units mounted on truck beds must be fastened securely without applying excessive stress on the receiver tank. We recommend installing a vibration isolator kit with gasoline engine models.

INSTALLING REMOTE AIR INLET PIPING _______________

•CAUTION Do not operate the unit without air inlet filtration.

If the air around the unit is relatively free of dirt, install the air inlet filter at the inlet connection at the pump. If the air is dirty, pipe the filter to a source of clean air. Use PVC plastic tubes for remote inlet piping. Do not use black pipe or galvanized pipe, as these promote sweating and rust. Consider installing an in-line type filter for ease of cleaning and replacement. Make the line as short and direct as possible and as large, or larger, than the diameter of the inlet connection on the pump. Do not install piping with a diameter lower than that of the pump intake.

Increase the pipe diameter one size for every 10 feet (3 m) of length or every 90° bend. Make sure the piping is adequately braced.

If you pipe the filter outdoors, cover it with a hood to prevent the entrance of rain or snow.

Heavy duty filter elements and filtration equipment are available for fine airborne dust, such as cement and rock dust.

INSTALLING DISCHARGE PIPING ______________________

•WARNING Do not use plastic pipe, soldered copper fittings, rubber hose, or lead-tin soldered joints anywhere in the compressed air system.

•CAUTION! If you will be using synthetic compressor lubricant, all downstream piping material and system components must be compatible. Refer to the following material compatibility list. If there are incompatible materials present in your system, or if there are materials not included in the list, contact Ingersoll-Rand for recommendations.

NOTE	All compressed air systems generate condensate
	which accumulates in any drain point (e.g. tanks,
	filters, drip legs, aftercoolers, dryers). This
	condensate contains lubricating oil and/or
	substances which may be regulated and must be
	disposed of in accordance with local, state, and
	federal laws and regulations.

GENERAL REQUIREMENTS. The piping, fittings, air receiver tank, etc. must be certified safe for at least the maximum working pressure of the unit. Use hard-welded or threaded steel or copper pipes and cast iron fittings that are certified safe for the unit’s discharge pressure and temperature. DO NOT USE PVC PLASTIC IN THE COMPRESSED AIR DISCHARGE LINE. Use pipe thread sealant on all threads, and make up joints tightly to prevent air leaks.
