SAFETY

1

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 protective equipment,

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

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.
