Caution is used to indicate the presence of a hazard which will or can cause minor personal injury or property damage if the warning is ignored.
Notice is used to notify people of installation, operation, or maintenance information which is important but not hazard-related.
SAFETY PRECAUTIONS BEFORE PROCEEDING, READ CAREFULLY BEFORE
COMPRESSOR OR PERFORMING WARNING
COMPRESSED AIR AND ELECTRICITY ARE DANGEROUS.
BEFORE DOING ANY WORK ON THIS UNIT, BE SURE THE ELECTRICAL SUPPLY HAS BEEN CUT OFF-LOCKED & TAGGED AND THE ENTIRE COMPRESSOR SYSTEM HAS BEEN VENTED OF ALL PRESSURE.
1. Do not remove the covers, loosen or remove any fittings, connections or devices when this unit is in operation. Hot liquid and air under pressure that are contained within this unit can cause severe injury or death.
2. The compressor has high and dangerous voltage in the motor starter and control box. All installations must be in accordance with recognized electrical codes. Before working on the electrical system, be sure to remove voltage from the system by use of a manual-disconnect-switch. A circuit breaker or fuse safety switch must be provided in the electrical supply line leading to the compressor.
Those responsible for installation of this equipment must provide suitable grounds, maintenance clearance and lightning arrestors for all electrical components as stipulated in O.S.HA 1910.308 through 1910.329.
3. Do not operate the compressor at higher discharge pressure than those specified on the Compressor Nameplate or motor overload will occur. This condition will result in compressor motor shutdown.
4. Use only safety solvent for cleaning the compressor and auxiliary equipment.
5. Install a manual shut off valve (isolation type) in the discharge line. A pressure relief valve, with sufficient capacity to relieve full compressor capacity, must be installed between the compressor and the isolation valve.
6. Whenever pressure is released through the pressure relief valve, it is due to excessive pressure in the system. The cause for the excessive pressure should be investigated immediately.
7. Before doing any mechanical work on the compressor:
a.) Shut the unit down.
b.) Electrically isolate the compressor by use of the manual disconnect switch in the power line to the unit. lock and tag the switch so that it cannot be operated.
c.) Vent pressure from the compressor and isolate the unit from any other source of air.
8. There can be adverse effects if compressor lubricants are allowed to enter plant air systems.
Air line separators, properly selected and installed, will minimize any liquid carryover.
The use of plastic bowls on line filters without metal guards can be hazardous. From a safety standpoint, metal bowls should be used on any pressurized system. Review of your plant air line system is recommended.
9. When a receiver is installed, it is recommended that occupational safety and health standards as covered in the Federal Register, Volume 36, number 105, part 11, paragraph 1910.169 be adhered to in the installation and maintenance of this receiver.
10. Before starting the compressor, its maintenance instructions should be thoroughly read and understood.
11. After maintenance functions are completed, covers and guards must be replaced.

& SAFETY SHUTDOWN CHECKHIGHAIRTEMPERATURE
There is a high discharge air temperature shutdown function built into the control on each compressor. it is factory pre-set at 228°F This function should be checked at regular intervals for proper operation, once a month Is recommended. PROCEDURE:

STATEMENT CONCERNING THE USE OF THIS EQUIPMENT FOR BREATHING AIR AND/OR AQUA LUNG SERVICE
If the model number on this air compressor contains letters "BAP", the compressor is suitable for use in breathing air services. In the absence of such a designation, the compressor is NOT considered as capable of producing air of breathing quality. For a compressor to be capable of use In air services It must be fitted with additional specialized to filter and/or the air to meet all applicable federal, state and local laws, rules, regulations and codes, such as, but not limited to, OSHA 29 CFR 1910.134, Compressed Gas Association G-7, 1-1966, Grade D Air and/or Canadian Standards Association. Should the purchaser and/or User fail to add such and proceeds to use the compressor for air service, the resulting therefrom without any responsibility or liability assumed
STATEMENT CONCERNING THE INADVERTENT BREATHING OF COMPRESSED AIR EXHAUST
"The purchaser/user shall insure that adequate ventilation and make air are provided if a non BAP des-ignated compressor supplies air in a confined area to air consuming such as air air tools, solenoids, air cylinders, air guns, nozzles, etc. The compressed air discharge stream residual coolants/lubricants/carbon monoxide/condensable hydrocarbons or other materials may be haz-ardous to health with inhalation."

The unit is shipped with a bolt in the motor sup-to prevent possible belt damage caused
bouncing during shipment. This bolt must be removed prior to motor rotation or oper-ating the unit.
In addition, a jackscrew is located under the base and offers support to the motor during shipment. This jackscrew must be loosened as far as ble without removing it to operating unit A locknut is provided to keep the jackscrew in place.
Locate the shipping bolt and in the motor as shown in 2.7-1 and remove the

Locate the rotation on the motor and check for correct rotation. The correct rotation when viewed from the drive end on the motor is clockwise.
If compressor is operated in the opposite direction of rotation, airend damage can result and is not warrantable.
