Electrical Shock Hazard

WARNING

Start Up

If pump is extemely cold, let it warm up to room

temperature before starting. If motor fails to start or

slows down significantly under load, shut off and

disconnect from power supply. Check that the voltage

is correct for motor and that motor is turning in the

proper direction. Turning in the wrong direction will

drastically reduce vane life. Vane life will be drastically

reduced if motor is not operating properly. Vanes can

break or be damaged if motor/pump runs in the wrong

direction.

OPERATION

WARNING

Injury Hazard

Air stream from product may contain solid or liquid

material that can result in eye or skin damage.

may exceed 85 db(A).

Failure to follow these instructions can result in eye

injury or other serious injury.

Pump only clean dry air.

Do not pump flammable or explosive gases or use

in an atmosphere that contains such gases.

Install proper safety guards as needed. Pumps with

glass jars need safety guards to protect against

breaking glass.

Use only recommended air handling parts acceptable

for pressure not less than 70 psi.

Keep fingers and objects away from openings and

rotating parts.

When provided, motor terminal covers must be in

place for safe operation.

Check that coupling guard and shroud are in place

before operating.

Product surfaces may become hot during operating,

This product must be connected to a grounded,

metallic, permanent wiring system, or an equipment

grounding terminal or lead on the product.

Power supply wiring must conform to all required safety

codes and be installed by a qualified person. Check

that supply voltage agrees with that listed on product

nameplate.

Extension cords:

Use only a 3-wire extension cord that has a 3-blade

grounding plug. Connect extension cord plug to a

Make sure your extension cord is in good condition.

Check that the gage wire of the extension cord is the

correct size wire to carry the current this product will

draw. Be sure the three phase motor turns in the proper

direction of rotation after installation. Turning in the

wrong direction will drastically reduce vane life.

It is your responsibility to operate this product at

recommended pressures or vacuum duties and room

ambient temperatures. Do Not start against a vacuum

or pressure load.

In the event of an electrical short circuit, grounding

reduces the risk of electric shock by providing an

escape wire for the electric current. This product may

be equipped with a power supply cord having a

grounding wire with an appropriate grounding plug.

The plug must be plugged into an outlet that is properly

installed and grounded in accordance with all local

codes and ordinances.

Model with a power supply cord:

This product must be grounded. For either 120-volt or

220/240-volt circuits connect power supply cord

grounding plug to a matching grounded outlet. Do not

use an adapter. (See DIAGRAM A)
