4 | Installation Isotemp Flammable Materials Storage Refrigerator
Installation
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 adequate
condensate drainage as well as proper door alignment 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 opposite 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.
Figure 1. Shelf Support
Install External probe in
Thermowell
An external temperature monitoring device can be added to
the thermowell beside the display thermowell mounted on top
of the unit. See Figure 2 for location of the thermowell.
Figure 2. Thermowell location
The size of the sensor must be less than 0.3 diameter to fit
inside the thermowell.
Requirements to install the external probe:
• Glycol mixture (50-50% solution of glycerine & water)
• Permagum as required

Isotemp Flammable Materials Storage Refrigerator Installation | 5
• Cable clamp
Figure 3. Inserting sensor in thermowell
To install the external probe in thermowell:
1. Add 2-3 ml of glycol solution in thermowell.
2. Insert the sensor in thermowell as shown in Figure 3 and
seal the opening with permagum.
3. Place the external monitoring device on top/side as per
your convenience.
4. Secure the excess wire using a cable clamp as shown in
Figure 4.
Figure 4. Securing excess wire
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 receptacle (NEMA 5-
15R) to minimize the potential of an electrical 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 connected to a minimum 15 amp
service.
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.
CAUTION: Be sure that the power supply is the
same voltage that is specified on the refrigerator’s
data plate.
WARNING: For personal safety this unit must be
properly grounded.
CAUTION: Do not use an extension cord. Use of
an ungrounded cord or an overloaded circuit
VOIDS the compressor warranty.
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.

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

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 compatibility 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 tetrachloride and
methyl alcohol, even though they are resistant to each
compound alone. This information is taken from Corrosion
and Corrosion Protection Handbook Second Edition
