Air Compressors
General Safety (Cont.)
IAWARNINGI
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 yaps;, .AJ_verstore
flammable liquids or gases in the vicini-
ty of the compressor.
I WARNINGI
Never operate compressor
without a beltguard. This m_ Q j
unit can start automatically _Jh._
without warning. Personal
injury or property damage could occur
from contact with moving parts.
9. Do not wear loose clothing or jewel-
ry that will get caught in the mov-
ing parts of the unit.
AI - --0-TI 0 NI
Compressor parts may be
hot even if the unit is
stopped.
10. Keep fingers away from a running
compressor; fast moving and hot
parts will cause injury and/or burns.
11. If the equipment should start to
vibrate abnormally, STOPthe
engine/motor and check immediate-
ly for the cause. Vibration isgener-
ally an indication of trouble.
12. To reduce fire hazard, keep
engine/motor exterior free of oil,
solvent, or excessive grease.
IAWARNINGI AnASME Sa -
ty relief valve with a
setting no higher than the Maximum
Allowable Working Pressure (MAWP) of
the tank MUST be installed in the air lines
or in the tank for this compressor. The
ASME safety valve must have sufficient
flow and pressure ratings to protect the
pressurized components from bursting.
The flow rating can be found in the parts
manual. 7he safety valve in the intercool-
er does not provide system protection.
Maximum operat.
IACAUTIONI ingpre ureis,75
psi for two-stage compressors and 135
-150 psi for single stage compressors. DO
not Operate with pressure switch or pilot
valves set higher than 175 psi (two-stage)
or 135- 150 psi (single stage).
13. Never attempt to adjust ASME safe-
ty valve. Keep safety valve free from
paint and other accumulations.
Never attempt to repair or
modify a tank! Welding,
drilling or any other modi.
fication will weaken the
tank resulting in damage from rupture
or explosion. Always replace worn,
cracked or damaged tanks.
[NOTICE ]Drainliquidfrom
tank daily.
14, Tanks rust from moisture build-up,
which weakens the tank, Make sure
to drain tank regularly and inspect
periodically for unsafe conditions
such as rust formation and corrosion.
15. Fastmoving air will stir up dust and
debris which may be harmful. Release
air slowly when draining moisture or
depressufizing the compressor system.
SPRAYING PRECAUTIONS
IAWARNINGI
Do not spray flammable
materials in vidnity of open
flame or near ignition
sources including the compressor unil_
16. Do not smoke when spraying paint,
insecticides, or other flammable
substances.
17. Use a face mask/respi-
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 as far away from the spray-
ing area as possible to 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
I_WARNING]
Disconnect. tag and lock
out power source then
release all pressure from
the system before attempting to
install, service, relocate or perform any
maintenance.
[ACAUTION1 _not lift or move
unit without appro.
priately rated equipment. Be sure the
unit is securely attached to lifting
device used. Do not lift unit by holding
onto tubes or coolers. Do not use unit
to lift other attached equipment.
Never use the
IACAUTIONI .oodshlpplng
skids for mounting the compressor.
install and operate unit at least 24"
from any obstructions in a clean, 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 space for maintenance.
Do not locata the
compressor air inlet
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 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-
sure. All pressurized components of the
air system must have a pressure rating
higher than or equal to the 200 psi for
