Installation - North Star M459231B.1 Installation, Operation And Maintenance Manual

SELECTING A LOCATION
Select a well lit indoor area with plenty of space for
proper cooling air flow and accessibility. Locate the
compressor at least 15 inches (38 cm) from walls,
and make sure the power supply is clearly identified
and accessible.
Temperature. Ideal operating temperatures are
between 40 and 100F (4 and 37 C). If
temperatures consistently drop below 32 F (0 C),
install the compressor inside a heated building. If this
is not possible, you must protect safety/relief valves
and drain valves from freezing.
CAUTION!
NEVER operate in temperatures below 15 F (-9C)
or above 125 F (52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 compressor is located in an unheated
area that is subject to large temperature changes.

CAUTION! If you will be using synthetic lubricant, all
downstream piping material and system components
must be compatible. Refer to suitable list on page 6.
General Requirements. The piping, fittings, etc.
must be certified for at least 4 times the working
pressure. Use hard-welded, threaded steel or copper
pipes and cast iron fittings that are certified safe for
the compressors discharge pressure and
temperature. DO NOT USE PVC PLASTIC. Use pipe
thread sealant on all threads, and make up joints
tightly to prevent air leaks.
Main Air Distribution Line. The main compressed
air distribution line should be of sufficient size to
minimize the pressure drop between the air supply
)
and the point of use. Slope the piping downward in
)
the direction of air flow to aid in the removal of
condensation at all drain points along the line. The
piping must be as short and direct as possible, and
adequately braced.
Drip Legs. A drip leg is a pipe extending downward
from the main line to collect condensation. Drip legs
should be at the lowest points in the air line and at
any point where the leg goes around an obstruction.
A drain valve should be installed at the bottom of
each drip leg.
Drop Legs. A drop leg is piping originating from the
main air distribution line that feeds air to an outlet for
tools or other air operated devices. Drop legs are
taken off the top of the main line so that
condensation does not easily flow into them. Drop
legs should be designed so that the air outlet comes
off the side of the drop leg, rather than the bottom.
By doing this, the condensation which is carried from
the main line collects below the outlet and prevents
moisture from entering the tool or device using the
air. A drain valve should be installed on the bottom of
each drop leg.
