Scientific channel and a complete understanding of this unit is
necessary to attain these objectives.
As the ultimate user of this apparatus, it is your responsibility
to understand its proper function and operational
characteristics.This instruction manual should be thoroughly
read and all operators given adequate training before
attempting to place this unit in service. Awareness of the
stated cautions and warnings, and compliance with
recommended operating parameters – together with
maintenance requirements – are important for safe and
satisfactory operation.The unit should be used for its intended
application; alterations or modifications will void the Warranty.
This product is not intended, nor can it be used, as a sterile or
patient connected device. In addition, this apparatus is not
designed for use in Class I, II or III locations as defined by the
US National Electrical Code, unless otherwise noted.
Alert Signals

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.
DANGER RISK OF CHILD ENTRAPMENT
Before you throw away your old 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.
Intended Use Statement
The 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:
Freezers: -12°C to -24°C (10.4°F to -11.2°F)
Explosion proof & FMS Freezers: -12°C to -24°C
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.
WARNING: Only Explosion Proof Units or
Flammable Material Storage Units are to be used
for the storage of flammable inventory/samples.
Note: Do not store corrosive materials in these units. Any
damage which occurs due to storage of corrosives will not be
covered under warranty claims.

Corrosive Materials Requiring Refrigerated or Frozen Storage
• Only use models rated as Corrosion Resistant.
• Corrosion Resistant does not mean Corrosion Proof –
Care in storage is still required.
• Store only corrosive reagents/samples which truly need
reduced temperature storage.
• Flammable corrosive materials require Flammable
Material Storage or Explosion Proof models labeled for
the storage of corrosives.
• Containers must be wiped clean of moisture and
chemical residue before being introduced into the unit
and upon return from use.
• Containers must be sealed with either vinyl tape or
Parafilm®.
• Reagents/samples which release HX (X= F, Cl, Br, I) on
contact with moisture (e.g. Acyl halides,
Organosilyl halides etc.) are particularly damaging to
metals.
• Volatile amines will react with HX depositing salts which
will lead to corrosion of metal surfaces.
• Volatile organic acids can exacerbate metal surfaces
already compromised, be sure these are securely sealed.
• Refrigerated compartments are cool or cold areas but
they are not to dry seal your reagents and samples.
• Bleach solutions release chlorine gas which can react
with other volatiles in the cooling chamber or directly
attacks metal surfaces.
• Periodically clean the interiors, clean up spills or leaking
containers.
• Failure to take precautionary actions may lead to damage
not covered by warranty claims Parafilm®is a registered

Explosion Proof and Freezers
Overview
Conventional 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 vapors. Such locations
are defined in (National Fire Protection Association) 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 epoxy enamel or ABS
plastic construction. Each unit is insulated throughout for
energy-efficient operation.
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.
WARNING: For FMS and EXP units where
flammable materials are stored in the cooling
chamber, the cooling chamber is considered a
Class I Div1 or Class I Zone 1 hazardous
location. Any monitoring devices placed in the
cooling chamber must have an intrinsically safe
rating from an appropriate certification body,
such as UL, CSA, FM etc. (this includes battery
or solar powered devices).
Thermocouples for building monitoring systems
must be wired through an electrical barrier
designed to provide isolation against voltage
and current spikes, which could cause a spark
resulting in fire or explosion. It is the end user's
responsibility to meet these requirements. The
Fisher Scientific channel cannot assist with the
selection of devices, recommend, approve or
design any device or monitoring circuit.
*The notation Class I, Groups C and D is an accepted
abbreviation for Class I, Div 1, Groups C and D; Class I Zone
1 Group IIB.

Flammable Material Storage Freezers
Overview
Conventional 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) 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.
(Commonly known as “Ordinary Locations”)
FMS units are NOT designed for use in Class I,
Division 1, Groups C and D environments, which require
an Explosion- Proof 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 epoxy enamel or ABS
plastic construction.Each unit is insulated throughout for
energy-efficient operation.
WARNING: For FMS and EXP units where
flammable materials are stored in the cooling
chamber, the cooling chamber is considered a
Class I Div1 or Class I Zone 1 hazardous
location. Any monitoring devices placed in the
cooling chamber must have an intrinsically safe
