General Safety Information
(Continued)
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, STOP the unit
and check immediately for the
cause. Vibration is generally a warn-
ing of trouble.
12. To reduce fire hazard, keep unit
exterior free of oil, solvent, or exces-
sive grease.
An ASME code safe-
ty relief valve with
a setting no higher than the tank maxi-
mum allowable working pressure 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.
Do not operate
with pressure
switch or pilot valves set higher than
the tank maximum allowable working
pressure.
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 modification will
weaken the tank resulting in damage
from rupture or explosion. Always
replace worn, cracked or damaged tanks.

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. Fast moving air will stir up dust and
debris which may be harmful. Release
air slowly when draining moisture or
depressurizing the compressor system.
Installation
Disconnect, tag and
lock out power source
then release all pres-
sure from the system
before attempting to install, service,
relocate or perform any maintenance.
Do not lift or move
unit without
appropriately 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
wood shipping
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 104
This will ensure an unobstructed flow
of air to cool compressor and allow
adequate space for maintenance.
Do not locate 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 on a flat,
even, concrete floor or on a separate
concrete foundation. Vibration isola-
tors should be used between the tank
leg and the floor. 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.
Failure to properly
install the tank can
lead to cracks at the
welded joints and pos-
sible bursting.
PIPING
pressed air. Serious injury or death
could result.
Any tube, pipe or hose connected 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 ASME safety
valve setting. Incorrect selection and
installation of any tube, pipe or hose

could result in bursting and injury.
