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 is present
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.
Safety Guidelines
This manual contains information that is
very important to know and understand.

General Safety
Sincethe air compressor and other
components (material pump, spray
guns, filters, lubricators, hoses,etc.)
used make up a high pressurepump-
ing system,the following safety pre-
cautions must be observed at all times:
included with this
product carefully.
l e a an aI 1
Be thoroughly
familiar with the controls and the
proper use of the equipment.
2. Follow all local electrical and safety
codes as well as the United States
National Electrical Codes (NEC) and
Occupational Safety and Health Act
(OSHA).
3. Only persons well acquainted with
these rules of safe operation should
be allowed to use the compressor.
4. Keep visitors away and NEVER
allow children in the work area.
5. Wear safety glasses and use
hearing protection when operating
the unit.

Breathable Air Warning
This compressor/pump is NOT
equipped and should NOT be used
"as is" to supply breathing quality
air. For any application of air for
human consumption, you must fit
the air compressor/pump with suit-
able in-line safety and alarm equip-
ment. This additional equipment is
necessary to properly filter and puri-
fy the air to meet minimal specifica-
tions for Grade D breathing as
described in Compressed Gas
Association Commodity
Specification G 7.1 - 1966, OSHA 29
CFR 1910. 134, and/or Canadian
Standards Associations (CSA).
DISCLAIMER OF WARRANTIES
In the event the compressor is used
for the purpose of breathing air
application and proper in-line safety
and alarm equipment is not simulta-
neously used, existing warranties
are void, and the company disclaims
any liability whatsoever for any
loss, personal injury or damage.
6. Do not stand on or use the unit as
a handhold.
7. Before each use, inspect compressed
air system and electrical components
for signs of damage, deterioration,
weakness or leakage. Repair or
replace defective items before using.
8. Check all fasteners at frequent
intervals for proper tightness.

General Safety (Cont.)
I_WARNINGI
Motors, electrical equip-
ment and controls can
cause electrical arcs that
will ignite a flammable gas or vapor.
Never operate or repair in or near a
flammable gas or vapor. Never store
flammable liquids or gases in the vicini-
ty of the compressor.
Never operate compressor
withoutabeltg.a . This U /
unit canstart automatically _-_
without warning. Personal
injury or property damage could occur
from contact with movingparts.
9. Do not wear Iooseclothing or jewel-
ry that will get caught in the mov-
ing parts of the unit.
Compressor parts may be
hot even if the unit is
stopped.
10. Keep fingers away from a running
compressor; fast moving and hot
parts win cause injury and/or burns.
11. If the equipment should start to
vibrate abnormally, STOP the
engine/motor and check immediate-
ly for the cause. Vibration is gener-
ally an indication of trouble.
12.To reduce fire hazard, keep
engine/motor exterior free of oil,
solvent, or excessive grease.

14. Tanks rust from moisture build-up,
which weakens the tank. Make sure
to drain tank regularly and inspect
periodically for unsafe conditions
suchas rust formation and corrosion.
15. Fast moving air will stir up dust and
debris which may be harmful. Release
air slowlywhen draining moisture or
depressurizing the compressor system.
SPRAYING PRECAUTIONS
IAWARNINGI
Do not spray flammable
materials in vldnity of open
flame or near i_'rtioe
sourcesincludingthe compressor unilL
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 as possibleto minimize over-
spray accumulation on the compressor.
19. When spraying or cleaning with sol-
vents or toxic chemicals, follow the
instructions provided by the chemi-
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
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-OFF VALVE
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
between the compressor pump and the
tank. Personal injury and/or equipment
damage may occur.Never use reducers
in discharge piping.
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-
