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?

FMS Refrigerator/Freezer
Installation
The power cord on this instrument is equipped with a
grounded NEMA 5-15P plug, which must be mated with a
NEMA 5-15R grounded receptacle.
The power cord of the FMS frig/freezer is equipped with a
3-prong grounding plug NEMA 5-15P, which mates with a
3-prong grounded receptacle, NEMA 5-15R. The cus-
tomer should have the wall receptacle and circuit checked
by a qualified electrician to verify the receptacle is
grounded.
Where a 2-prong receptacle is encountered, it is the
responsibility of the customer to have it replaced with a
properly grounded 3-prong receptacle.
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.
Loading Procedures
There is no mechanical air circulating system within this
unit. Therefore, if minimum temperature variation is
desired, allow clearance between each item for adequate
gravity convection air circulation.
11
INSTALLATION
Warning
For personal safety, this unit must be
properly grounded before use.
Caution
Do not under any circumstances, cut
or remove the ground prong from the
power cord. DO NOT USE A 2-PRONG
PLUG ADAPTER.
Caution
Be sure the voltage supplied to the
refrigerator/freezer is equal to that
specified on the data plate.
Caution
The aluminum evaporator and other
portions of these units should not be
exposed to the corrosive effects of
acidic or caustic materials. Extreme
care must be exercised if such materi-
als are stored within to prevent voiding
the warranty.
Warning
Under no circumstances should any-
one open the door of this refrigerator
or freezer cabinet while in the vicinity
of a lit cigarette or a glowing or heated
object. The vapor pressure of chemi-
cals is greatly reduced with refrigera-
tion, however vapors may still be pres-
ent which could ignite in the presence
of heated objects.
Warning
Do no store edible items with chemi-
cals.

The refrigerator and freezer sections of the unit each
have a separate access door. The freezer section is locat-
ed in the upper section of the unit.
The refrigerator/freezer is energized through a thermostat
on the top of the unit.
The graduated thermostat dial on these units is not meant
to be a direct indicator of operating temperatures. Also,
reference settings and resultant temperatures may vary
slightly from unit to unit, and it may be necessary to make
slight adjustments when seasonal or drastic changes
occur in ambient conditions.
12
Operation
Warning
Never open the screw type cover to
gain access to the thermostat in
order to change temperature set-
tings or perform any kind of service
unless electrical power to the unit
has been turned OFF and the sur-
rounding area has been cleared of
combustible vapors. See Fig. 2.

13
At colder settings in humid atmospheres or after pro-
longed use, it may become necessary to defrost the unit.
Defrost the unit when any frost becomes 1/4” to 1/2” thick.
Defrosting may become necessary more often if doors
are opened more frequently or the unit is operating in a
high humidity condition.
Defrosting
To defrost the unit, remove the contents from the refriger-
ator/freezer and adjust the temperature control full clock-
wise for the Explosion-Proof Refrigerator and counter
clockwise for the FMS Refrigerator. Allow the unit several
hours to completely defrost. While the refrigerator is
defrosting, water will collect in the base of the unit.
Sponge up the water as it collects in the bottom compart-
ment.
Also, place a folded towel at the front of the compartment
to soak up water that would otherwise run down the front
of the refrigerator.
Cleaning
The cabinet interior should be cleaned frequently. Any
spilled liquid should be wiped off immediately since stains
resulting from some spills could be permanent if not
quickly removed. The most convenient time to clean the
interior is after defrosting.
A mild detergent and lukewarm water or solution of bicar-
bonate of soda (1 tablespoon per gallon of water) is rec-
ommended for cleaning the interior and exterior of the
cabinet.
Surfaces should be rinsed and dried carefully and thor-
oughly.
The exterior of the cabinet should be cleaned occasional-
ly with a damp cloth of mild detergent and water. Do not
use an abrasive or harsh detergent on these surfaces.
Clean door gaskets with mild suds, rinse with clear water
and wipe dry.
Maintenance
Caution
Do not use sharp or pointed instru-
ments as a scraper. Damage to the
evaporator may occur.
Caution
Do not use any type of abrasive such
as steel wool or fluids such as gaso-
line, naphtha, or paint thinner that
could be harmful to plastic materials,
door gasket and/or painted surface.

Cleaning Behind the Unit
Place a hard surfaced strip under the front legs to prevent
damage to the floor covering. Carefully move the unit
straight out. If necessary, vacuum the wire and tube con-
denser on the back of the refrigerator.
Cleaning the Defrost Pan
The defrost water pan, located on the top of the compres-
sor at the rear of the refrigerator, should be cleaned at
least once a year. Simply empty and wipe clean with a
damp cloth. DO NOT REMOVE THE PAN.
After cleaning, move the refrigerator back into position,
reconnect power to the unit, and turn the thermostat knob
to the desired setting.
14
MAINTENANCE
Warning
Always disconnect power to the unit
when moving the refrigerator to
clean behind it.

15
Troubleshooting
If the refrigerator is not operating properly, it may be a minor problem that is easily corrected. A few things to
check are as follows:
A. Does not run, be sure that:
1. Thermostat knob is positioned to cool refrigerator.
2. Power is connected to unit.
3. Circuit breaker or fuse has not been blown.
B. Runs continuously:
1. If the unit gets too cold from continuous running, turn the control knob to a warmer setting.
Clockwise for Explosion- Proof refrigerators and counter clockwise for FMS refrigerators.
2. If constant running does not cool cabinet adequately, check for heavy frost build-up on the refrigera-
tion coil.
C. Noise:
The refrigerator/freezer has been designed for operation at a minimum noise level. All mechanical refrigera-
tors make some noise, but this does not necessarily indicate trouble. Hissing, gurgling and churning noises
(low level) are caused by the circulation of refrigerating gases within the system and are normal.
D. Clicking Sound:
In case the compressor overheats, a safety device will shut of the motor, thereby preventing damage. This
safety device, a thermal protector, functions to prevent damage to the motor windings in case of overload,
overheating or improper power supply. A clicking sound occurring about every 20 seconds, indicates that the
thermal protector is functioning. If this happens, turn the unit off and turn off the power supply to the unit. The
problem causing this action must be corrected before the unit is put back into
service.
E. Low Voltage:
In certain areas the voltage may be subject to fluctuation. Low voltage is one of the major causes of refrigera-
tion failure. Low or fluctuating voltage may be the result of overloaded power lines or inadequate wiring. This
condition may be noticed only during certain periods; and should it occur, we recommend contacting the local
power company and/or a electrician.
F. Insufficient Cooling:
Cause Remedy
Unit frosted Defrost
Thermostat set at warm setting Change thermostat to colder setting.
Condenser coil is dirty Clean with vacuum
NOTE: If the above actions do not correct the problem, contact Service @ 1-800-438-4851.
