INSTALLATION AND OPERATING INSTRUCTIONS
The Installation and Operating Instructions should be
read carefully before starting the unit.
LOCATION -- The compressor should be installed in a
clean, well--lighted place, with plenty of space all
around it, and in such a manner as to be accessible
from all sides. Do not place the unit too near other ma-
chinery or too close to the wall. The unit should be set
on a firm foundation, with the feet shimmed to eliminate
rocking and undue stresses when bolted to the founda-
tion.
AIR FILTER -- The intake of every compressor should
be equipped with an air filter to prevent dust and other
abrasives from being drawn into the cylinders.
In cases where no air filter is installed, the company will
assume no responsibility for excessive wear of the pis-
tons, piston rings, cylinder bore or valve details, even
though such wear occurs very soon after the compres-
sor is installed. To operate properly, filters must be kept
clean.
INLET LINE -- Where an inlet line is used between the
air filter and the compressor, it must be thoroughly
cleaned on the inside to prevent dirt or scale from enter-
ing the compressor. If welded construction is used,
the line must be shot blasted and cleaned to re-
move welding scale. In either case, the inlet line must
be coated internally by galvanizing or painting with a
moisture and oil--proof sealing lacquer. Up to ten (10)
feet in length, the inlet line should be the full size of the
inlet opening on the compressor. If an extra--long line
is necessary, the pipe size should be increased accord-
ing to FIGURE 1, below.
Accessibility for inlet air filter servicing must be consid-
ered when relocating the filters from the unit to a remote
location.
PIPING -- Air discharge pipe must be the full size of the
discharge opening on the air cylinder. The discharge
pipe should be as short and direct as possible, eliminat-
ing short bends and fittings and avoiding pockets. A
Pressure Relief Valve must be placed in the discharge
line between the compressor and any shutoff valve,
check valve or aftercooler. The discharge line should
be piped to the lowest opening in the air receiver.
Discharge air used for breathing will
cause severe injury or death.
Consult
filtration
specialists
for
additional filtration and treatment
equipment to meet health and safety
standards.
Do
not
operate
the
compressor
without the proper pressure relief
valve. Overpressure operation may
cause severe damage to equipment
and personal injury.
As the air cools in being carried through the distributing
lines to the point at which it is to be used, it deposits
moisture mixed with a small amount of oil. This mois-
ture is objectionable in pneumatic tools, sand blasting,
paint spray work and similar operations. Much of the
trouble with water in the air lines can be overcome if
small receivers to act as collecting tanks are put in the
lines at frequent intervals, otherwise suitable moisture
traps should be used.
AIR RECEIVER -- When possible locate the air receiv-
er outside the building where it has an opportunity to
radiate the most heat. A drain cock should be located
at the lowest point in the receiver for drawing off at least
once a day the accumulated oil and water. Where there
is danger of freezing, the pressure relief valve should
