Important Information ________________

Safety Precautions

!

 WARNING

For your safety, the information in this manual must
be followed to minimize the risk of fire or explosion
or to prevent property damage, personal injury, or loss
of life.

The dryer must never be operated with any of the back
guards, outer tops, or service panels removed.
Personal injury or fire could result.

Do not store or use gasoline or other flammable vapors and
liquids in the vicinity of this or any other appliance.

Purchaser/user should consult the local gas supplier for proper
instructions to be followed in the event the user smells gas.
The instructions should be posted in a prominent location.

What To Do If You Smell Gas…

Do not try to light any appliance.

Do not touch any electrical switch.

Do not use any phone in your building.

Clear the room, building, or area of all occupants.

Immediately call your gas supplier from a neighbor’s phone.
Follow the gas supplier’s instructions.

If you cannot reach your gas supplier, call the fire department.

Installation and service must be performed by a qualified
installer, service agency, or gas supplier.

Dryer(s) must be exhausted to the outdoors.

Although ADC produces a very versatile dryer, there are some
articles that, due to fabric composition or cleaning method,
should not be dried in it.

!

 WARNING

Dry only water washed fabrics.  Do not dry articles
spotted or washed in dry cleaning solvents, a
combustible detergent, or “all purpose” cleaner.
Explosion could result.

Do not dry rags or articles coated or contaminated
with gasoline, kerosene, oil, paint, or wax.  Explosion
could result.

Do not dry mop heads.  Contamination by wax or
flammable solvents will create a fire hazard.

Do not use heat for drying articles that contain plastic,
foam, sponge rubber, or similarly textured rubber
materials.  Drying in a heated tumbler may damage
plastics or rubber and may be a fire hazard.

A program should be established for the inspection and cleaning
of lint in the heating unit area, exhaust ductwork, and inside
the dryer.  The frequency of inspection and cleaning can best
be determined from experience at each location.

!

 WARNING

The collection of lint in the burner area and exhaust
ductwork can create a potential fire hazard.

For personal safety, the dryer must be electrically grounded in
accordance with local codes and/or the National Electrical Code
ANSI/NFPA NO. 70-LATEST EDITION or in Canada, the
Canadian Electrical Codes Parts 1 & 2 CSA C22.1-1990 or
LATEST EDITION.

NOTE:

 Failure to do so will void the warranty.

Under no circumstances should the dryer door switches, lint
door switch, heat safety circuit ever be disabled.

!

 WARNING

Personal injury or fire could result.

This dryer is not to be used in the presence of dry cleaning
solvents or fumes.

Remove articles from the dryer as soon as the drying cycle
has been completed.

!

 WARNING

Articles left in the dryer after the drying and cooling
cycles have been completed can create a fire hazard.

Do not operate steam dryers with more than 150 PSI (10.34
bars) steam pressure.  Excessive steam pressure can damage
steam coil and/or harm personnel.

Replace leaking flexible hoses or other steam fixtures
immediately.  Do not operate the dryer with leaking flexible
hoses.  Personal injury may result.

READ AND FOLLOW ALL CAUTION AND DIRECTION
LABELS ATTACHED TO THE DRYER.

!

 WARNING

You must disconnect and lockout the electric supply
and the gas supply or the steam supply before any
covers or guards are removed from the machine to
allow access for cleaning, adjusting, installation, or
testing of any equipment per OSHA standards.
