General; Personal Protective Equipment; Pressure Release - Sullair LS-20S Operator's Manual And Parts List

1.1 GENERAL

Sullair Corporation and its subsidiaries design and
manufacture all of their products so they can be op-
erated safely. However, the responsibility for safe
operation rests with those who use and maintain
these products. The following safety precautions
are offered as a guide which, if conscientiously fol-
lowed, will minimize the possibility of accidents
throughout the useful life of this equipment.
The compressor should be operated only by those
who have been trained and delegated to do so, and
who have read and understood this Operator's
Manual. Failure to follow the instructions, proce-
dures and safety precautions in this manual can re-
sult in accidents and injuries. Read this manual prior
to startup.
NEVER start the compressor unless it is safe to do
so. DO NOT attempt to operate the compressor with
a known unsafe condition. Tag the compressor and
render it inoperative by disconnecting and locking
out all power at source or otherwise disabling its
prime mover, so others who may not know of the un-
safe condition, cannot attempt to operate it until the
condition is corrected.
Install, use and operate the compressor only in full
compliance with all pertinent regulations and all ap-
plicable Federal, State, and Local codes, standards
and regulations.
DO NOT modify the compressor and/or controls in
any way except with written factory approval.
While not specifically applicable to all types of com-
pressors with all types of prime movers, most of the
precautionary statements contained herein are ap-
plicable to most compressors and the concepts be-
hind these statements are generally applicable to all
compressors.

1.2 PERSONAL PROTECTIVE EQUIPMENT

Prior to installing or operating the compressor, own-
ers, employers and users should become familiar
with, and comply with, all applicable regulations and
any applicable Federal, State and Local codes,
standards, and regulations relative to personal pro-
tective equipment, such as eye and face protective
equipment, respiratory
equipment intended to protect the extremities, pro-
tective clothing, protective shields and barriers and
electrical protective equipment, as well as noise ex-
posure administrative and/or engineering controls
and/or personal hearing protective equipment.

1.3 PRESSURE RELEASE

A. Install an appropriate flow--limiting valve between
the service air outlet and the shut--off (throttle)
valve, either at the compressor or at any other point
along the air line, when an air hose exceeding 1/2"
(13mm) inside diameter is to be connected to the
shut--off (throttle) valve, to reduce pressure in case
protective equipment,
of hose failure, per all applicable Federal, State and
Local codes, standards and regulations.
B. When the hose is to be used to supply a manifold,
install an additional appropriate flow--limiting valve
between the manifold and each air hose exceeding
1/2" (13mm) inside diameter that is to be connected
to the manifold to reduce pressure in case of hose
failure.
C. Provide an appropriate flow--limiting valve at the
beginning of each additional 75 feet (23m) of hose in
runs of air hose exceeding 1/2" (13mm) inside diam-
eter to reduce pressure in case of hose failure.
D. Flow--limiting valves are listed by pipe size and
rated CFM. Select appropriate valves accordingly,
in accordance with their manufacturer's recommen-
dations.
E. DO NOT use air tools that are rated below the
maximum rating of the compressor. Select air tools,
air hoses, pipes, valves, filters, and other fittings ac-
cordingly. DO NOT exceed manufacturer's rated
safe operating pressures for these items.
F. Secure all hose connections by wire, chain or oth-
er suitable retaining devices to prevent tools or hose
ends from being accidentally disconnected and ex-
pelled.
G. Open fluid filler cap only when compressor is not
running and is not pressurized. Shut down the
compressor and bleed the sump (receiver) to zero
internal pressure before removing the cap.
H. Vent all internal pressure prior to opening any
line, fitting, hose, valve, drain plug, connection or
other component, such as filters and line oilers, and
before attempting to refill optional air line anti--icer
systems with antifreeze compound.
I. Keep personnel out of line with and away from the
discharge opening of hoses or tools or other points
of compressed air discharge.
J. Use air at pressures less than 30 psig (2.1 bar) for
cleaning purposes, and then only with effective chip
guarding and personal protective equipment.
K. DO NOT engage in horseplay with air hoses as
death or serious injury may result.
L. DO NOT tamper with sump and unit (if provided)
relief valves. Check the relief valve as recom-
mended in the Maintenance Section of this manual
or at a minimum of at least weekly to make sure it is
not blocked, clogged, obstructed or otherwise dis-
abled. DO NOT change the factory setting of the re-
lief valve.
M. If the compressor is installed in an enclosed
area, it is necessary to vent the relief valve to the
outside of the structure or to an area of non--expo-
sure.
