Unpacking
Save all packing material if apparatus is received dam-
aged. This merchandise was carefully packed and thor-
oughly inspected before leaving our factory.
Responsibility for its safe delivery was assumed by the
carrier upon acceptance of the shipment; therefore, claims
for loss or damage sustained in transit must be made
upon the carrier by the recipient as follows:
Visible Loss or Damage
Note any external evidence of loss or damage on the
freight bill, or express receipt, and have it signed by the
carrier’s agent. Failure to adequately describe such exter-
nal evidence of loss or damage may result in the carrier’s
refusing to honor your damage claim. The form required
to file such a claim will be supplied by the carrier.
Concealed Loss or Damage
Concealed loss or damage refers to loss or damage,
which does not become apparent until the merchandise
has been unpacked and inspected. Should either occur,
make a written request for the carrier’s agent within 15
days of the delivery date; then file a claim with the carrier
since the damage is the carrier’s responsibility.
If you follow the above instructions carefully, we will
guarantee our full support of your claim to be compensat-
ed for loss from concealed damage.
DO NOT – FOR ANY REASON – RETURN THIS UNIT

Explosion-Proof Refrigerator/Freezers and Flammable
Material Storage (FMS) Refrigerator/Freezers have dis-
tinct features. Understanding the proper application for
each is necessary to assure safe operation.
Explosion-Proof
Refrigerator/Freezer
The Explosion-Proof Refrigerator/Freezer (13-986-116A/
10ECEEFSA) has been designed to store volatile or
flammable materials and can be used in hazardous loca-
tions containing explosive atmospheres. These units are
also suitable for storing such volatile materials as ethyl
ether, hexane, naptha, methyl, ethyl ketone, acetone, ben-
zol, butane, gasoline, alcohols, cyclopropane, lacquers,
solvents, fuels, pharmaceuticals, and anesthetics.
Explosion-Proof Refrigerators (13-986-116A/
10ECEEFSA) comply with the following:
A. UL listed, Commercial Refrigerator/Freezer for
hazardous locations, control number 27R2.
B. Suitable for use in Hazardous Locations;
Operating Temperature Code T4A, Class 1,
groups C & D., Class I Zone 1 Group IIB
C. Occupational Safety and Health Standards,
29CFR 1910.307.
FMS Refrigerator/Freezer
The FMS refrigerator/freezer (13-986-111A/10FCEEFSA)
has been designed to provide maximum protection for
storing and refrigerating volatile or flammable materials.
When used in a ventilated laboratory, non-hazardous
area, this product complies with the following code,
Federal Agency Standard and Listing.
A. National Fire Protection Association Code
NFPA 45
B. UL listed, Special Purpose Refrigerator.

Applications
Note
This instrument can also be used in
non-hazardous areas, where you
wish to refrigerate volatile or flam-
mable materials.
Warning
THIS PRODUCT IS NOT
APPROVED TO BE USED IN HAZ-
ARDOUS LOCATIONS CONTAIN-
ING EXPLOSIVE ATMOSPHERES.

For proper installation follow the instructions below:
Leveling the Unit
Adjustable legs at the front corners of the refrigerator
should be adjusted so that the refrigerator is firmly posi-
tioned on the floor and the front is raised just enough that
the door closes easily when opened halfway. Turn leveling
legs clockwise to raise and counterclockwise to lower, see
Fig. 1.
Explosion-Proof Refrigerator
Installation
IMPORTANT: PLEASE READ CAREFULLY
This unit is for free standing installation only. The appro-
priate materials and wiring methods must be used in order to
comply with current NFPA No. 70 NEC. for Class I, Group C
and Group D Hazardous Locations and Local Codes.
Determine the total amount of current presently being
used by other apparatus connected to the circuit that will
be used by this unit. It is critical that this added current
not exceed the rating of the fuse or circuit breaker in use.
Installation
Warning
If the unit is tilted in excess of 30
degrees, level the unit, then wait 12
hours before applying power.
Tu rn clockwise to raise, counter-
clockwise to lower.
Figure 1
Warning
BEFORE ANY ELECTRICAL
CONNECTIONS ARE MADE, BE
SURE THERE IS NO EXPLOSIVE
CONCENTRATIONS IN THE AREA.
Caution
Be sure the voltage supplied to the
refrigerator/freezer is equal to that
specified on the data plate.
Warning
For personal safety, this unit must be
properly grounded before use.
The National Electrical Code (NEC) must be referred to
for proper fusing and service conductor size and type.

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.

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.
Electric Connection Check Points
• Have proper connections been made at the
junction box?
• Is the junction box lid fastened tightly to the
junction box?
• Are all wire connections secure?
• Are the service conductor sizes adequate to
carry rated load?
• Is the unit properly grounded?
• Is the unit connected to a properly fused branch
circuit?
