Introduction

This manual provides information on how to safely install and perform maintenance on the Toshiba TEFC

3Ø Motor Oil Mist Lubrication System.

The information within this manual applies to the Toshiba TEFC 3Ø Motor with anti-friction bearings only.

Oil mist is an aerosol vapor comprised of an oil and air mixture; one-to-20,000, respectively, is typical.

The high-pressure mist is passed through an orifice (Reclassifier) that increases the speed of the oil/air

flow and combines the smaller oil particles before the mist is passed through to the bearing housing.

The Oil Mist Lubrication System is the preferred lubrication system of the Hydrocarbon Processing Industry.

This is because the system is hermetically sealed, has no moving parts, and uses only new oil (no

recirculation) — this results in significantly reduced bearing failures.

To maximize the abilities of the Oil Mist Lubrication System, a working familiarity with this manual is

required. This manual has been prepared for the Oil Mist Lubrication System installer and maintenance

personnel.

This manual may also be used as a reference guide. With this in mind, use this manual to develop a

familiarity with the Oil Mist Lubrication System before attempting to install any elements of the system,

transfer oil, or perform system maintenance.

Safety Information and Precautions

Oil Mist Lubrication I-M Manual

Safety Precautions

Qualified Personnel

Installation, operation, and maintenance shall be

performed by Qualified Personnel Only. A

Qualified Person is one that has the skills and

knowledge relating to the construction, installation,

operation, and maintenance of the electrical

equipment and has received safety training on the

hazards involved (Refer to the latest edition of

NFPA 70E for additional safety requirements).

Qualified Personnel shall:

• Have carefully read the entire manual.

• Be familiar with the construction and

function of the equipment being monitored

and the hazards involved.

• Be able to recognize and properly address

hazards associated with the application.

• Be trained and authorized to safely

energize, de-energize, ground, lock out/tag

out circuits and equipment, and clear faults

in accordance with established safety

practices.

• Be trained in the proper care and use of

protective equipment such as safety shoes,

rubber gloves, hard hats, safety glasses,

face shields, flash clothing, etc., in

accordance with established safety

practices.

For further information on workplace safety, visit

www.osha.gov.

Note: For ALL references to the National

Electrical Code (NEC), see the latest

release of the National Electrical Code.

• Only Qualified Personnel should install

this equipment.

• Turn off and lock out/tag out all power

sources before proceeding to connect the

power wiring to the equipment.

Installation Precautions

The installation, operation, maintenance and

disposal of the equipment shall be done in

accordance with this manual and all applicable

national, state and local codes.

High voltages and rotating parts of electrical

machinery can cause fatal or serious injury and/or

property damage if improperly installed or serviced.

Lock out all power prior to servicing, performing

maintenance, or repairs on the equipment.

Do not by-pass or render safeguards or protective

safety devices inoperative.

The machine must be electrically grounded in

accordance with all applicable electrical codes.

Comply with all applicable national, state and local

codes. Adhere to all applicable ANSI, IEEE, NEMA,

OSHA, NEC (NFPA 70) and NFPA 70E

Maintenance Procedures pertaining to the

installation and operation of polyphase motors.

Ensure that steps are taken to protect all personnel

from possible injury (e.g., install guards, post

warning signs, etc.).

Provide proper safeguards for personnel against

accidental contact of personnel or clothing with

rotating parts.

Avoid extended exposure to equipment with noise

levels above OSHA code 29 CFR part 1910.95

(85 dbA and above over an eight hour period).

Do not modify Explosion Proof motors. Modifying an

Explosion Proof Motor may result in the voiding of

the UL Listing and possibly preventing the motor

from containing an explosion.

The shaft key must be fully secured before motor is

energized.

Upon completion of the motor installation or

maintenance, replace or install all guards and

covers.

Enhanced precautions are required if using the Oil

Mist system on a motor that uses automatic thermal

protection. The system must be completely

disabled when an automatic start up could result in

destruction of property or injury to personnel.

Safety Information and Precautions

Oil Mist Lubrication I-M Manual

Oil Installation and

Maintenance

Installation

The motor bearings will receive a light coat of oil for

testing at the factory and for subsequent shipping.

Upon receipt of the motor, the oil-mist system must

be connected.

For motors labeled Provisions Only for Oil Mist

Lubrication or Oil Mist Ready, purge all oil and/or

grease from the bearings.

Remove the oil inlet and oil outlet pipe plugs from

the bearing brackets, caps, or remove the extension

tubes from the drive end and non-drive ends of the

motor.

Install the specified reclassifier to the top

connection.

Connect the oil recovery trap to the bottom opening.

Oil Supply

The lubricating oil should be rust- and oxidation-

inhibited, stray-mist suppressed, and manufactured in

accordance with established commercial standards

and practices.

The viscosity shall be ISO VG 68 or higher, per the

latest revision of ASTM D 2422.

The flash point shall be 350° F (177° C) or above.

The pour point shall be -15° F (-26° C) or above.

See Table 1 on page 3 for oil recommendations.

The oil type and misting unit must be compatible.

Storage

Motors that are labeled Provisions Only for Oil Mist

Lubrication have bearings that are packed with

grease. The storage procedures are the same as

those for motors with grease-lubricated anti-friction

bearings.

Motors that are labeled Oil Mist Ready have

bearings that are protected for temporary storage

by a corrosion inhibitor. ff extended storage (greater

then 3 months) or if stored outdoors, the units

should be connected to the oil mist system while in

storage.

If this is not possible, at three-month intervals, the

grease level should be checked and refilled as

required.

At each three-month check the shaft should be

rotated by hand five revolutions minimum to re-

distribute the bearing grease.

The bearing grease must be removed at the time of

connection to the oil mist system.
