Safety Information
Thank you for selecting Cardinal Health products for your equipment needs. These instructions contain
important operating and safety information. The user must carefully read and understand these instructions
before using the unit. Your unit has been designed to optimize function, reliability, safety and ease of use. It
is the user’s responsibility to install the unit in conformance with local electrical codes.
Alert Signals
DANGER RISK OF CHILD ENTRAPMENT
Before you throw away your old refrigerator or freezer:
Take off doors 
Leave the shelves in the place so that children may not easily climb inside. 
If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.

Safety Alert
Important operating instructions. To reduce the risk of injury or
poor performance of the unit read the user manual before
putting the equipment into operation.
WARNING Indicates an immediately hazardous situation, which if not
avoided, will result in death or serious injury.
CAUTION Indicates an immediately hazardous situation, which if not
avoided, may result in minor to moderate injury.
(No symbol)
CAUTION (Without Safety Alert Symbol) indicates a situation that may
result in property damage.
Shock Hazard
Use of this equipment involves power supplies which convert
line voltage to low voltage power. Do not modify or use power
supplies other than OEM equipment. Connection of the power
supply may require a properly grounded receptacle. Potential
for electrical shock or equipment damage exists if precautions
are not followed.
Frost bite/ Low
Temperature Avoid contact with cold freezer surfaces potential for cold burns or skin sticking to cold surfaces.

Intended Use Statement
The Refrigerators/Freezers described in this manual are for professional use only. These
products are intended for use in research for the storage of samples or inventory in the
following temperature ranges :
Refrigerators +1°C to +12°C
Freezers -12°C to -20°C
Only Explosion Proof Units or Flammable Material Storage Units are to
be used for the storage of flammable inventory/samples.
These are not considered medical devices and have therefore not been registered with a
medical device regulatory body (e.g. FDA): that is, it has not been evaluated for the storage
of samples for diagnostic use or for samples to be re-introduced to the body.

Explosion-Proof
Refrigerators and Freezers
Overview
Conventional refrigerators and freezers are not suitable for storing
flammable materials. Such units have components in their electrical
and refrigeration systems that can trigger explosions of flammable air-
vapor mixtures inside the unit and/or in the immediate surrounding
area.
The Authority having Jurisdiction (AHJ) determines if work areas are
designated as a hazardous location with respect to the presence of
flammable gases or vapours. Such locations are defined in (National
Fire Protection Agency) NFPA 70 Articles 500-501 and OSHA 29
CFR1910.307. Some of these classified areas are expected to
experience concentrations of flammable gases and/or vapors at or
above their lower flammability limits for extended periods of time.
The construction of our explosion-proof units has been evaluated by
Underwriters Laboratories (UL) and are suitable for use in classified
areas requiring Class I, Groups C and D* protected equipment. The
electrical components such as thermostats, wiring, splices, relays and
compressor motors on explosion-proof units are safely housed within
explosion-proof enclosures and conduit. Compressor surface
temperatures have been evaluated and determined to remain below the
flash point of materials found in Class I, Groups C and D.
All models have heavy-gauge, rigid, steel construction with a durable
enamel finish. Interiors have HIPS plastic construction. Each unit is
insulated throughout for energy-efficient operation.
These units are ideal for storing ethyl ether, acetone, alcohol,
benzene, gasoline, hexane, lacquer solvent vapors, naphtha, along
with many other potentially hazardous materials.
*The notation Class I, Groups C and D is an accepted abbreviation for
Class I, Div 1, Groups C and D.

Flammable Materials Storage
Refrigerators and Freezers
Overview
Conventional refrigerators and freezers are not suitable for
storing flammable materials. Such units have components in
their electrical and refrigeration systems that can trigger
explosions of flammable air-vapor mixtures inside the unit.
Flammable Materials Storage (FMS) refrigerators/freezers are
designed for use in locations, which are not classified by the
Authority Having Jurisdiction (AHJ) as hazardous.
Under normal operating conditions the build up or
presence of flammable vapors will not occur in the
environment external to the unit.
FMS units are NOT designed for use in Class I, Groups
C and D environments, which require an Explosion-
Proof Refrigerator/Freezer.
FMS units are designed and evaluated by Underwriters
Laboratories (UL) to meet the requirements of the National Fire
Protection Association Standards Nos. 45, 70 and 99. These
units have no internal electrical components that could trigger an
explosion or fire of hazardous materials inside the unit.
These units are ideal for storing cyclopropane, ethyl ether,
ethylene, acetone, alcohol, benzene, butane, gasoline, hexane,
lacquer solvent vapors, naphtha, natural gas or propane along
with many other potentially hazardous materials.
All models have heavy-gauge, rigid, steel construction with a
durable enamel finish. Interiors have HIPS plastic construction.
Each unit is insulated throughout for energy-efficient operation.
WARNING: DO NOT store flammable materials in
General Purpose Laboratory Refrigerator / Freezers.
Risk of explosion, fire and injury may occur.
For flammable materials use either a Flammable
Material Storage Unit or an Explosion Proof Unit.

General-Purpose Laboratory
Refrigerators/Freezers
Overview
These are general-purpose units available in all
refrigerator, all freezer and combination
refrigerator/freezer models. These units are
intended for basic laboratory use only. Storage of
high-value, life science materials or clinical biological
materials may require alarm, monitoring, back-up and
temperature performance features. The need to add
these features should be determined by your
industrial hygienist or safety officer. These units are
not suitable for corrosive environments.
WARNING: DO NOT store flammable materials in
General Purpose Laboratory Refrigerator / Freezers.
Risk of explosion, fire and injury may occur.
For flammable materials use either a Flammable
Material Storage Unit or an Explosion Proof Unit.
