Air
Compressors
Description
Air compressor units are intended to
provide compressed air to power pneu-
matic tools, operate spray guns and sup-
ply air for pneumatic valves and actua-
tors. The pumps supplied with these
units have oil lubricated bearings. A
small amount of oil carryover ispresent
in the compressed air stream.
Applications requiring air free of oil
vapor should have the appropriate filter
insta[led. The air compressor units are to
be mounted per the instructions provid-
ed on a solid floor. Any other use of
these units will void the warranty and
the manufacturer will not be responsi-
ble for problems or damages resulting
from such misuse. Refer to the enclosed
"Replacement Parts Manual" to identify
compressor as single stage or two-stage.

16. Do not smoke when spraying paint,
insecticides, or other flammable
substances.
17. Use a face mask/respi- FA,,.ah- _
rator when spraying
and spray in a well ven-
tilated area to prevent
health and fire hazards.
18. Do not direct paint or other sprayed
material at the compressor. Locate
compressor asfar away from the spray-
ing area aspossibleto minimize over-
spray accumulation on the compressor.
19. When spraying or cleaning with sol-
vents or toxic chemicals, follow the

cal manufacturer.
Installation
IAWARNING]
Disconnect, tag and lock
out power source then
release all pressure from
the system before attempting to
install, service, relocate or perform any
maintenance.
A_--CAUTION] Donotliftormove
unit without appro-
priately rated equipment. Be sure the
unit issecurely attached to lifting
device used. DOnot lift unit by holding
onto tubes or coolers. Do not use unit
to lift other attached equipment.
Never use the
wood shipping
skids for mounting the compressor.
Install and operate unit at least 24"
from any obstructions in a dean, well
ventilated area. The surrounding air
temperature should not exceed 100=F.
This will ensure an unobstructed flow
of air to cool compressor and allow
adequate spacefor maintenance.
Do not locate the
]ACAUTIONI compressoralrlnlet
near steam, paint spray, sandblast areas
or any other source of contamination.
NOTE: If compressor operates in a hot,
moist environment, supply compressor
pump with clean, dry outside air.
Supply air should be piped in from
external sources.
TANK MOUNTING
The tank should be bolted into a flat,
even, concrete floor or on a separate
concrete foundation. Vibration isolators
should be used between thetank leg
and the floor. Model MP345800AJ isola-
tor pads are recommended for horizon-
tal units. Model MP345700AJ isolator
pads are recommended for vertical units.
When using isolator pads, do not draw
bolts tight. Allow the pads to absorb
vibrations. When isolators are used, a
flexible hose or coupling should be
installed between the tank and service
piping.
FAWARNING]
Failure to properly install
the tank can lead to cracks
at the welded jointa and
possible bursting.
PIPING
IAWARNINGI Never use plastic
(PVC) pipe for com-
pressed air. Serious injury or death
could result.
Any tube, pipe or hoseconnectedto the
unit must be able to withstand the tem-
perature generated and retain the pres-
sure. All pressurized components of the
air systemmust have a pressure rating
higher than or equal to the 200 psifor

gle stage compressors ASME safety valve
setting. Incorrect selection and installa-
tion of any tube, pipe or hose could result
in bursting and injury. Connect piping sys-
tem to tank using the same size fitting as
the discharge port.
INSTALLING A SHUT-OFFVALVE
A shut-off valve should be installed on
the discharge port of the tank to control
the air flow out of the tank. The valve
should be located between the tank and
the piping system.
(AWARNING] Neverinstalla

When creating a permanent]y installed
system to distribute compressed air, find
the total length of the system and select
pipe size from the chart. Bury under-
ground lines below the frost line and
avoid pockets where condensation can
gather and freeze.
Apply air pressure to the piping installa-
tion and make sure all joints are free
from leaks BEFOREunderground lines
are covered. Before putting the compres-
sorinto service,find and repair all leaks
in the piping, fittings and connections.

Installation (cont.)
Recommended wire sizes may be larger
than the minimum setup by local ordi-
nances. If so,the larger size wire should
be used to prevent excessive line voltage
drop. The additional wire cost isvery
small compared with the cost of repair-
ing or replacing a motor electrically
"starved" by the use of supply wires
which are too small.
GROUNDING
electrical components arel I
shock hazards. Make sure ]_I
all the components are
properly grounded to prevent death or
serious injury.
This product must be grounded.
Grounding reduces the risk of electrical
shock by providing an escape wire for
the electric current if short circuit
occurs. This product must be installed
and operated with a power cord or
cable that has a grounding wire.

CONTINUOUS RUN OPERATION
TO convert to continuous run operation a
separate unloading device must be
installed bythe user between the pump
and the tank. The existing check valve
must be removed.
CRANKCASE BREATHER
During severe operating conditions or
initial start-up, some oil may accumulate
at the crankcase breather opening. This
isnormal and will diminish as the pump
accumulates run time and the piston
rings become fully seated.
Maintenance
I_WARNING1
Disconnect, tag and lock
out power source then
release all pressure from
the system before
attempting to install, service, relocate
or perform any maintenance.
In order to maintain efficient opera-
tion of the compressor system, check
the air filter and oil level before each
use. The ASME safety valve should also
be checked daily (See Figure 8). Pull
ring on safety valve and allow the ring
to snap back to normal position. This
valve automatically releases air if the
tank pressure exceeds the preset maxi-
mum. If air leaks after the ring has
been released, or the valve isstuck and
cannot be actuated by the ring, the
ASME safety valve must be replaced.
Do not attempt to
tamper with the
ASME safety valve.
Figure 8
TANK
Never attempt to repair
or modify a tank!
Welding, drilling or any
other modification will
weaken the tank resulting in damage
from rupture or explosion. Always
replace worn, cracked or damaged
tanks.
[NOTICE ]Drain liquid from
tank daily.
The tank should be carefully inspected
at a minimum of once a year. Look for
cracks forming near the welds. If a crack
is detected, remove pressure from tank
immediately and replace.
COMPRESSOR LUBRICATION
See Operation. Add oil asrequired. The
oil and oil filter should be changed every
three months or after every 500 hours of
operation; whichever comesfirst. Only
pressure lubricated pumps have an oil
filter.
AIR FILTER
Never run the compressorpump without
an intake air filter nor with a clogged
intake air filter. Use compressedairto
blow the filter clean. Do not wash or oil
the element. If it cannot be blown clean,
the filter mustbe replaced. Operating
compressorwith a dirty filter cancause
high oil consumptionand increaseoil con-
tamination in the dischargeair."
