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.

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
WITHOUT FIRST OBTAINING AUTHORIZATION.

Selecting
a
Location
Choose a location for the refrigerator that
will
provide at
least three inches of clearance between the cabinet
and
any adjacent vertical surface at
the sides and rear.
Twelve
inches of clearance is required above the grille.
Appropriate electrical power must
be available.
Locate the
refrigerator within eight feet of
the power outlet
so that no
extension cord is required.
Leveling the Unit
The refrigerator must be level in order to provide ade-
quate condensate drainage as well as proper door align-
ment and operation. The refrigerator should be in its final
operating location and set so that it is firmly positioned on
the floor.
There are four leveling legs – one for each corner.
These
legs are packed in the accessory carton from which they
must be removed and installed onto the cabinet.
In order
to install the legs, carefully tip the cabinet rearward and
add (4) two inch blocks underneath and simply screw the
threaded leg studs into the case bottom front leg holes.
Repeat this procedure by tilting the cabinet in the oppo-
site direction and install the remaining legs.
Make sure
that the legs are tightened extremely well or the entire unit
will sway or rock with each opening or closing of the
doors, possibly causing damage to the case bottom.
Level
the cabinet front to rear and side-to-side using the corner
leveling screws located at the bottom of the legs.
Shelves
Shipped inside each cabinet are shelves packed in plastic
and a bag of shelf supports. Two different types of shelf
supports are used. Refer to figure 1 for installation.
Shelf
spacing is adjustable to suit user requirements.
Replacement shelves are available individually for the
Laboratory Refrigerators.
Installation
Use 1/4” support in front of
shelf and 1/2” support here

Tab Length
Electrical Connection
Determine the total amount of current presently being
used by other apparatus connected to the circuit that will
be used by this refrigerator. It is critical that this added
current demand and other equipment on this circuit not
exceed the rating of the fuse or circuit breaker in use.
The frequency and nominal voltage requirements for the
unit are specified on the data plate, which is located on
the interiors upper left side. Only plug the unit into a
power source that meets these requirements. Low line
voltage is often the cause of service complaints. With the
unit running, check that the line voltage is within ±10% of
that specified on the data plate.
The power cord of this instrument is equipped with a three
prong (grounding) plug (NEMA 5-15P). This plug mates
with a standard three prong (grounding) wall recep-tacle
(NEMA 5-15R) to minimize the potential of an elec-trical
shock hazard. The customer should have the wall
receptacle and circuit checked by a qualified electrician to
verify the receptacle is properly grounded and is connect-
ed to a minimum 15 amp service.
Warning
Do not under any circumstances cut or
remove the third (ground) prong from the
power cord.
Do not use a two-prong adapter plug.
Where a two-prong wall receptacle is encountered, it is
the personal responsibility and obligation of the user to
have it replaced with a properly grounded three-prong
receptacle.

INSTALLATION
Warning
For personal safety this unit must be
properly grounded.
Caution
Be sure that the power supply is the
same voltage that is specified on the
refrigerator’s data plate.
Caution
Do not use an extension cord.
Use of
an ungrounded cord or an overloaded
circuit VOIDS the compressor
warranty.
Initial Startup
Turn power on and verify that the condenser fan is running.
This model has a condenser fan located on the condensing
unit on top of the cabinet.
Temperature Control
The thermostat is factory set to provide an interior
temperature of 38°F (4°C). To adjust the interior
temperature, there is a hole in the top of the case to allow
access the adjustment screw. For operation above an alti-
tude of 3000 ft., have the thermostat adjusted by a techni-
cian. See photo below.
Temperature Display
Interior temperature is indicated in degrees C by the solar
powered LCD display mounted in the header panel.

Operation
Warning
If the unit is tilted in excess of 30
degrees, do not apply electrical power
for a minimum of 12 hours.

Material Compatibility
The interior cabinet of this unit is constructed of anodized
aluminum. Care must be exercised when determining
which chemicals may be stored in the refrigerator and
freezer sections and which type of storage materials
should be employed.
ABS Plastic deteriorates when exposed to, but not limited
to, the following:
Aliphatic Hydrocarbons; Aromatic Hydrocarbons; Fully
and Partially Halogenated Hydrocarbons; Alcohols
Monohydric; Phenols; Ketones; Esters; Ethers; Organic
Acids (concentrates and dilute); and Concentrated
Oxidizing Acids. This information is taken from Plastics

Aluminum Alloys are susceptible to corrosion when
exposed to but not limited to most inorganic acids, bases
and salts with a pH outside of their passive range of pH 4
to 9. It is also important to recognize that the compatibili-
ty of aluminum alloys with mixtures of organic compounds
cannot always be predicted from their compatibility with
each of the compounds. For example, some aluminum
alloys are corroded severely in mixtures of carbon tetra-
chloride and methyl alcohol, even though they are resist-
ant to each compound alone. This information is taken
from Corrosion and Corrosion Protection Handbook
