Explosion-Proof
Refrigerators and Freezers
Overview
Conventional refrigerators and freezers are not only unsuitable for storing flammable materials; they can create potential hazards in a facility. Such units have several components in their electrical and refrigeration systems that can
trigger explosions of flammable air-vapor mixtures inside the
unit or from the immediate surrounding area.
Motors and thermostats are designed to prevent the arcing
that can ignite a flammable air-vapor mixture. In addition,
each unit has wiring, splices, thermostats, relays and compressor motors safely housed within an explosion-proof
enclosure, the construction being suitable for use in Class I,
Groups C and D. This means that things like the surface
temperature of compressors will remain below the flash
point of any flammable material likely to be found in Class I,
Groups C and D locations.
All models have heavy-gauge, rigid, braced-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 will prevent potentially destructive explosions in
any facility by meeting the standards established by
Underwritersʼ Laboratory, Inc., OSHA and National Fire
Protection Association for storage of hazardous materials.
Thermo Scientific Explosion-Proof Refrigerators and
Freezers are 100% explosion-proof. They also meet
National Fire Protection Standards as found in Articles 500501 and provide total protection while storing reagents at or
below ambient temperatures.

Flammable Materials Storage
Refrigerators and Freezers
Overview
These units will prevent potentially destructive explosions
in any facility by meeting the standards established by
Underwritersʼ Laboratory, Inc., OSHA and National Fire
Protection Association for storage of hazardous materials.
They also are designed to comply with National Fire
Protection Association Standards Nos. 45 and 99, as well
as OSHA Article No. CFR1910.308. Thermo Scientific
Flammable Materials Storage Refrigerators/Freezers are
manufactured for safe, cold storage of volatile materials.
Flammable Material Storage (FMS)
Refrigerators/Freezers will prevent an explosion from
occurring inside the unit. These units have no internal
electrical components that could trigger an explosion of
hazardous materials inside the unit. They are NOT
designed for use in Class I, Groups C and D environments. For these locations use a Thermo Scientific
Explosion-Proof Refrigerator. However, FMS units are
not suitable for use in Class I, Group C and D environments.
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 cabinets have heavy-gauge steel construction with a durable exterior finish of epoxy enamel. A well
insulated cabinet and tight sealing magnetic door prevent
air leaks along with helping to lower operating costs. The
interior is made of porcelain-enameled steel or ABS plastic.

INSTALLATION
How to Seal Killark® Box Conduit with Fiber and
Sealing Compound to Help Protect Against
Explosions (Explosion-Proof Units Only):
The purpose of the procedure that follows is to build fiber
rope dams on the left and right hubs of the horizontal conduit.
The fiber rope damns will surround conduit wiring that is
housed inside the horizontal conduit.
When both the left and right fiber rope dams have been
pressed into place, sealing compound is poured between the
two and forms into an airtight plug.
All of this is done in order to prevent the very real threat of
gas entering the Killark box and a resulting serious explosion.
After the unit wires have been pulled through the horizontal
conduit the following procedure is required:
•
•
•
•
Turn power off at the circuit breaker before proceeding.
Place a small amount of sealing compound granules, enclosed, into a clean mixing vessel. Add
small amounts of water while stirring until a thick
paste is formed, then carefully continue adding
smaller amounts of water until a thick gravy consistency is achieved—NOT WATERY. Discard any
material that becomes too stiff to use. Never
attempt to restore workability by stirring in more
water.
Locate silver Killark box, back/top-center of unit.
Unscrew conduit domed-cover.

• Insert fiber rope material down into horizontal conduit opening. Pressing down firmly, work the material into
the left hub and—most importantly—being sure the material COMPLETELY SURROUNDS THE WIRING,
from the top to the bottom, completely blocking this end of the horizontal conduit.
• Insert fiber rope material down into horizontal conduit opening. Pressing down firmly, work the material into
the right hub and—most importantly—being sure the material COMPLETELY SURROUNDS THE WIRING,
from the top to the bottom, completely blocking this end of the horizontal conduit.
22
INSTALLATION
• Pour sealing compound down in between the two fiber rope dams filling the remaining space. Pour slowly,
being careful not to trap air bubbles. Immediately wipe off any spilled sealing compound.
• Screw conduit domed-cover back onto conduit opening.
NOTE: INITIAL SETUP OF SEALING COMPOUND WILL OCCUR IN APPROXIMATELY 30 MINUTES HOWEVER, THE SEALING COMPOUND REQUIRES A MINIMUM OF 8 HOURS ABOVE 32ºF TO DEVELOP
SUFFICIENT STRENGTH TO WITHSTAND EXPLOSIONS.

Start-Up Procedure
Rotate the control knob clockwise to lower the temperature and counterclockwise raise it.
To check chamber temperature, place a dial thermometer
on a shelf in the center of the chamber. Initially, rotate the
temperature control knob to an arbitrary setting. Allow
approximately 2 hours for the temperature to initially stabilize. Check the temperature and compare with the dial
setting.
Adjust dial further to reach the desired operating temperature. After chamber initially stabilizes, allow 1/2 to 1 hour
for the chamber temperature to stabilize after subsequent
temperature adjustments.
Because the markings on the dial do not indicate specific
temperatures, use them AS REFERENCE POINTS ONLY
for any future setting of the temperature.
If the room thermostat is turned below 60ºF at night, consider setting the temperature control one step colder. It
should be left at this setting for the nighttime period;
return temperature control to original setting when the
room thermostat is returned to its normal setting.
Restart Procedure
If unit is unplugged or turned off, allow 3 minutes before
restarting or plugging it back in.

the temperature decreases from the set point
then turns off when the freezer has achieved set
point again. This lamp will also light when the
unit is turned on and is still at room temperature
and will turn off when the unit begins to cool.
Deep Freezing, Bottom, Yellow: This light will
glow when the thermostat is rotated fully clockwise to “super.” This position keeps the compressor fully on until the normal cycle for the
freezer is turned on. It will get to the low-end
temperature faster until you want to regulate the
temperature. The deep freeze (super) mode
can be kept on at all times if desired.

OPERATION
How to Save Energy
•
•
•
•
•
•
•
•
Be sure to follow location suggestions as mentioned in the previous INSTALLATION section.
Wipe moisture from glassware or other materials
before placing them in a unit.
Don't overcrowd the unit. Too many items can
increase electrical energy demand in order to
keep everything cool.
Close the door as soon as possible in hot,
humid weather.
Make certain that the door is closed tightly.
As soon as frost has accumulated to 1/4”,
defrost.
Keep containers covered, when possible, to
reduce moisture buildup.
Set operating temperature no colder than necessary for the items being refrigerated.
Safety Tips
•
•
•
26
After a unit is in operation, do not touch the cold

TEMPERATURE DISPLAY (4):
10
Digital devices generally do not round off a reading. In the
case of this temperature monitor, when the display
reports, say a value of 10 degrees, that “10” can represent any temperature from 10.0 to 10.9 degrees.
Therefore, a very small change (0.1 degree or less), or a
minor electronic disturbance many cause the displayed
temperature to change one digit. Only when the displayed
temperature is changing within a period of 20 seconds or
greater can the change be related to real thermal changes
in the space of time being monitored.
READING AND ADJUSTING ALARM POINTS:
To read or set alarm points press the Display button (10)
under the HIGH (3) or LOW ALARM DISPLAY (9) and
while keeping it depressed, turn the adjustment screw(s)
located under ADJUST (2, 8) slowly to set the desired
alarm setpoint. (On dual alarm points, only ONE setting
can be adjusted at a time.)
27
OPTIONAL EQUIPMENT
ALARM CONDITIONS:
•
HIGH SETPOINT ALARM: If the probe temperature exceeds the HIGH setpoint (or falls below
the LOW setpoint on dual setpoint models), the
audio alarm will sound the red ALARM status
lamp (6) will flash.
The unitʼs audio alarm can temporarily be
silenced by depressing the DELAY button (7).
The alarm is shipped set with a 30-minute delay.
During the delay period, the alarm will chirp
about every 30 seconds and the alarm status
lamp (6) to flash during the delay period.
•
If the alarm condition is still present at the end
of the preset 30-minute delay period, the audio
alarm will turn on with full intensity.
LOW TEMPERATURE ALARM (9): This alarm is
triggered by the temperature falling below the
desired setpoint. It is important that this low
alarm point be set at a lower temperature than
the high alarm.
RELAY OUTPUT:
The relay output consists of a SPDT relay that changes
state with a loss of line power OR the presence of an
alarm condition. The contacts are rated at 30V/1Amp.

Troubleshooting
In the event that your unit is not operating properly, check the following before calling for service assistance—
this may save you the cost of unnecessary service calls.
Symptom
Unit not operating.
Unit runs continuously.
Possible Cause of Problem
Make certain that the unit is connected to a grounded outlet.
Make certain that temperature control knob is ON.
Check that circuit breaker is not tripped or fuse is not blown.
Make certain that there is no heavy frost accumulation. If there is, defrost
unit.
Look at condenser to see if there is layer of dust or lint. Clean if required
with a dry brush or vacuum.
A leak around the door gasket will allow cold air to escape. This causes unit
to work harder than necessary to maintain cold temperatures. Re-seat or
replace the gasket if worn.
If you have temperature set too cold, this may cause unit to run
continuously. Check optimum running temperature.
Is the ambient air over 43ºC (109ºF), or the units located close to heat
sources? If possible, move to a different location.
Noise problems.
An unusually high frequency of door openings and closings can increase
operating load. Unit will stabilize as these are decreased.
This can be caused by contents of unit being set too close and rattling
against each other. Rearrange contents as needed.
Hissing or gurgling noise is caused by refrigerating fluid circulating and is
normal.
Noise can result if unit is not level on floor. Check with level.
Fan noise: normal airflow can cause this, not a problem.
29
