Air
Compressors
Description
Air compressorunits are intended to
provide compressedair to power pneu-
matic tools, operate sprayguns and sup-
plyair 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
installed. The air compressorunits are to
be mounted per the instructionsprovid-
ed on a solidfloor. Any other useof
these units will void the warranty and
the manufacturer will not be responsi-
ble for problems or damages resulting
from suchmisuse.Refer to the enclosed
"Replacement PartsManual" to identify
compressorassingle stage or two-stage.

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 usedbetween the tank leg
and the floor. Model MP345800AJ isola-
tor padsare recommendedfor horizon*
tal units. Model MP345700AJisolator
padsare recommended for vertical units.
When using isolatorpads,do not draw
bolts tight. Allow the padsto absorb
vibrations.When isolatorsare used,a
flexible hoseor coupling should be
installed between the tank and service
piping.
[AWARNINGI
Failure to properly install
the tank can lead to cracks
at the welded joints and
possible bursting.
PIPING
IAWARNINGI Neveruseplastic
(PVC) pipe for corn-
pressed air. Serious injury or death
could result.
Any tube, pipe or hoseconnected to the
unit must be able to withstand the tem-
perature generated and retain the pres-

I_CAUTIONI TAINSNOOI--
Before operating compressor. Fillto the
center of the sight gauge or maximum
mark on dipst_ (see_gure 5).
Some residualoil may still bein the pump
leaving athin coat on the sight glass,
however; there isnot enough oil to oper-
ate the unit. Fillpump with single-viscosi-
ty, ISO100, non-detergent, compressor
oil. Recommended ST126700AVcom-
pressor oil or Mobil 1" 5W30 or 10W30
synthetic oil may also be used.Add oil
onlythrough the oil fill plug. Pouring oil
into any other orifice will causeoil to leak
and spray out during operation. Fill to

If the compressorisrun under humid
conditions for short periods of time, the
humidity will condense in the crankcase
and causethe oil to look creamy. Oil
contaminated by condensed water will
not provide adequate lubrication and
must be changed immediately. Using
contaminated oil will damage bearings,
pistons, cylinders and rings and isnot
covered under warranty. To avoid water
condensation in the oil, periodically run
the compressor with tank pressure near
150 psifor two-stage compressorsor 120
psi for singlestage compressorsby open-
ing the drain cockor an air valve con-
netted to the tank or hose.Runthe
pump for an hour at atime at least once
aweek or more often if the condensa-
tion reoccurs.
IMPORTANT: Change oil after first50
hoursof operation.

The compressor unit starts and stops
based on preset pressureswitch set-
tings. The pressure switch contains an
unloader which isa small valve that

CONTINUOUS RUN OPERATION
To convert to continuous run operation a
separate unloading device must be
installedby the userbetween the pump

must be removed.
ORANKCASE BREATHER
During severe operating conditions or
initial start-up, some oil may accumulate
at the crankcase breather opening. This
isnormal and will diminish asthe pump
accumulates run time and the piston
ringsbecome fully seated.
Maintenance
I W.=d NINGI
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.
Drain liquid from
I NOTICE J 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
isdetected, remove pressurefrom 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 SO0hoursof
operation; whichever comesfirst.Only
pressure lubricated pumps have an oil
filter.
AIR FILTER
Never run the compressorpump without
an intake air filter norwith aclogged
intake air filter. Usecompressedair to
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 increase oil con-
tamination inthe dischargeair.
