INSTALLATION
SELECTING A LOCATION
For most electric motor units, select a relatively clean and dry well-lighted
indoor area with plenty of space for proper ventilation, cooling air ow and
accessibility. Provide 1,000 cubic feet of fresh air per 5 horsepower. Locate
the unit at least 15 inches (38 cm) from walls, and make sure the main
power supply is clearly identied and accessible.
Unless the electrical components of the unit are specially protected for
outdoor use, do not install an electric motor unit outdoors or in an area
that will expose the electrical components to rain, snow or sources of
appreciable moisture.
The electric drain valve incorporates arcing or sparking parts,
such as snap switches, receptacles and the like that tend to
produce arcs or sparks and, therefore, when located in a garage,
the compressor should be in a room or enclosure provided for
the purpose, or the electric drain valve should be 18 inches (457
mm) or more above the oor.
AMBIENT TEMPERATURE CONSIDERATIONS
Ideal operating temperatures are between 32°F and 100°F (0°C and 37.8°C).
If temperatures consistently drop below 32°F (0°C), install the compressor
in a heated area. If this is not possible, you must protect safety/relief valves
and drain valves from freezing. If temperatures are consistently below 40°F
(4.4°C), consider installing an external crankcase heater kit, especially if the
compressor has diculty starting.
Never operate the compressor in temperatures below 20°F
(6.6°C) or above 104°F (40°C).
HUMID AREAS
In frequently humid areas, moisture may form in the pump and produce
sludge in the lubricant, causing running parts to wear out prematurely.
Excessive moisture is especially likely to occur if the unit is located in an
unheated area that is subject to large temperature changes.
Two signs of excessive humidity are external condensation on the pump
when it cools down and a“milky” appearance in petroleum lubricant.
You may be able to prevent moisture from forming in the pump by
increasing ventilation, operating for longer intervals or installing an
external crankcase heater kit.
NOISE CONSIDERATIONS
Consult local ocials for information regarding acceptable noise levels in
your area. To reduce excessive noise, use vibration isolator pads or intake
silencers, relocate the unit or construct total enclosures or bae walls.
MOUNTING
Remove the unit from the skid before mounting.
Bolt the unit to a rm, level foundation (such as a concrete oor). 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.

INSTALLING REMOTE AIR INLET PIPING
Do not operate the unit without air inlet ltration.
If the air around the unit is relatively free of dirt, install the air inlet lter
at the inlet connection at the pump. If the air is dirty, pipe the lter 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 lter 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 lter outdoors, cover it with a hood to prevent the entrance
of rain or snow.
Heavy duty lter elements and ltration equipment are available for ne
airborne dust, such as cement and rock dust.

INSTALLING DISCHARGE PIPING
Do not use plastic pipe, soldered copper ttings, rubber hose, or
lead-tin soldered joints anywhere in the compressed air system.
