ÈABOUT THIS MANUAL

ËScope—This instruction manual is intended to provide preventive maintenance, service procedures, and

mechanical parts identification for the Milnor®72072 dryer.

See the safety manual for safety instructions before installing, servicing, or operating this machine. See the

installation guide for facility requirements, installation instructions, and assembly instructions. See the operator

guide for operator instructions. See the reference manual for programming, operating, and troubleshooting instruc-

tions. See the schematic manual for electrical parts identification and electrical troubleshooting.

ËManual Number/Date Code (When To Discard or Save)—The manual number/date code is lo-

cated on the inside front cover, upper right corner just above the manual name. Whenever the manual is reprinted

with new information, part of this number changes. If the date code after the “/” changes, the new version applies

to all machines covered by the old version, but is improved— thus the old version can be discarded. If the

manual number before the “/” changes, the new manual covers only new machines. Example: Discard MAT-

MODELAE/8739CV when MATMODELAE/8739DV is received (minor improvements). Also, discard MAT-

MODELAE/8739DV when MATMODELAE/8746AV is received (major improvements). But keep

MATMODELAE/8746FV when MATMODELBE/8815AV is received, since the new manual no longer applies to

machines originally shipped with the old manual.

ËDocuments and Change Bars—The individual documents comprising this manual use the same revision

criteria as the manual. Text documents also display change bars. Example: When section MSOP0599AE/9135BV

becomes MSOP0599AE/9135CV, change bars with the letter “C” appear next to all changes for this revision. For

a major rewrite (e.g., MSOP0599AE/9226AV), all change bars are deleted.

SAFETY FOR INSTALLATION AND SERVICE

General Safety Requirements

(specific warnings, next page and throughout manual)

Incorrect installation, neglected preventive maintenance, abuse, and/or improper repairs or changes to the

machine can cause unsafe operation and personal injuries, such as multiple fractures, amputations, or death. The

owner or his selected representative (owner/user) is responsible for understanding and ensuring the proper operation

and maintenance of the machine. The owner/user must familiarize himself with the contents of all machine instruc-

tion manuals. The owner/user should direct any questions about these instructions to a Milnor®dealer or the Mil-

nor®Service department. Most regulatory authorities (including OSHA in the USA) hold the owner/user ultimately

responsible for maintaining a safe working environment. Therefore, the owner/user must do the following:

•recognize all foreseeable safety hazards within his facility and take actions to protect his personnel,

equipment, and facility

•require that personnel are familiar with all functional and safety aspects of the machine

•ensure safety devices installed on the machine are in place and properly maintained

•ensure all machine parts and assemblies are properly maintained.

ËLaundry Facility—Provide a supporting floor that is strong and rigid enough to support--with a reasonable

safety factor and without undue or objectionable deflection--the weight of the fully loaded machine and the forces

transmitted by it during operation. (For washer-extractors, see “ABOUT THE FORCES TRANSMITTED BY MIL-

NOR®WASHER-EXTRACTORS.”) Provide sufficient clearance for machine movement. Provide any safety

guards, fences, restraints, devices, and verbal and/or posted restrictions necessary to prevent personnel, machines,

or other moving machinery from accessing the machine or its path. Provide adequate ventilation to carry away heat

and vapors. Ensure service connections to installed machines meet local and national safety standards, especially

regarding the electrical disconnect (see the National Electric Code). Prominently post safety information, including

signs showing the source of electrical disconnect.

COLLISION, CRUSHING, AND PINCH HAZARDS—Serious bodily injury or death

can result to personnel in proximity to machinery/systems that traverse, ele-

vate, extend, pivot, and/or tilt. The following mandatory minimum safety rer-

quirements must be installed with the machinery system:

☞Safety fence inclosing machine movement areas,

☞Lockable electric interlocks on all gates, properly interfacedas shown on machine sche-

matics, to disable machine movement when any gate is opened,

☞Signs to alert personnel to these hazards, placed prominently around the fenced area.

☞Local codes may require additional precautions.

ËPersonnel—Inform personnel about hazard avoidance and the importance of care and common sense. Provide

personnel with the safety and operating instructions that apply to them. Verify that personnel use proper safety and

operating procedures. Verify that that personnel understand and abide by point-of-hazard tags on the machine and

procedure-specific precautions in the instruction manuals.

ËSafety Devices—Ensure that no one eliminates or disables any safety device on the machine or in the facility.

Do not allow machine to be used with any missing guard or cover. Service any failing or malfunctioning device

before operating the machine.

ËMaintenance—Ensure the machine is inspected and serviced in accordance with the norms of good practice and

with the preventive maintenance schedule. Replace belts, pulleys, brake shoes/disks, clutch plates/tires, rollers,

seals, alignment guides, etc; before they are severely worn. Immediately investigate any evidence of impending

failure and make needed repairs (e.g., cylinder, shell, or frame cracks; drive components such as motors, gear boxes,

bearings, etc; whining, grinding, smoking, or becoming abnormally hot; bending or cracking of cylinder, shell,

frame, etc.; leaking seals, hoses, valves, etc.) Do not permit service or maintenance by unqualified personnel.

Hazards During Assembly

SHOCK HAZARD—Electrical source can cause death or severe injury. Connec-

tions from the machine main bus to the wall disconnect must be made by a

competent electrician.

☞NEVER make electrical connections without locking OFF and tagging out

power at the wall disconnect.

When lowering basket housing onto base, keep body parts away from sections

being joined.

Sufficient clearance and access must be provided on all sides for service pro-

cedures.
