2. Safety Precautions
In this manual, the following symbols and conventions are used.
WARNING: This symbol when used alone indicates important operating instructions to reduce the
risk of injury or poor performance of the unit.
WARNING: This symbol indicates potentially hazardous situations which, if not avoided, could result
in serious injury or death.
WARNING: This symbol indicates situations where dangerous voltages exist and has a potential for
electrical shock.
WARNING: This symbol indicates potentially hazardous situations, which if not avoided could result
in re.
CAUTION: This symbol, in the context of a CAUTION, indicates a potentially hazardous situation
which if not avoided could result in minor to moderate injury or damage to the equipment. This
indicates a situation which may result in property damage.
CAUTION: This symbol indicates surfaces which may become hot during use and may cause burns
if touched with unprotected body parts.
WARNING: Before installing, using or maintaining this product, be sure to read the manual and
product warning labels carefully. Failure to follow these instructions may cause the product to
malfunction, which could result in injury or damage.
CAUTION: This symbol indicates possible pinch points which may cause personal injury.
WARNING: The snowake symbol indicates low temperatures and risk of frost bite. Do not touch
bare metal or samples with unprotected body parts.
Below are important safety precautions that apply to this product.
CAUTION: Use this product only as described in the product literature and in this manual. Before
using it, verify that the product is suitable for its intended use. If the equipment is used in a manner
not specied by the manufacturer, the protection provided by the equipment may be impaired.
CAUTION: Do not modify system components, especially the controller. Use OEM exact
replacement equipment or parts. Before use, conrm that the product has not been altered
in any way.
WARNING: Your unit must be properly grounded in conformity with national and local electrical
codes. Do not connect the unit to overloaded power sources.
WARNING: Disconnect the unit from all power sources before cleaning, troubleshooting, or
performing other maintenance on the product or its controls.
WARNING: This unit is not for storage of ammable materials.
WARNING: Units are charged with hydrocarbon refrigerant (R290). Only qualied service personnel
should service this unit.

WARNING: Unauthorized repair of your unit will invalidate your warranty. Contact Technical Service
at 1-866-984-3766 for additional information.
DANGER: Risk of re or explosion. Flammable refrigerant used to be repaired only by trained
service personnel. Do not puncture refrigerant tubing.
WARNING: No equipment that uses an open ame should be placed inside the refrigerator. This will
harm the unit, hamper functionality and compromise your safety.
CAUTION: Do not use any battery powered or externally-powered equipment in the refrigerator.
Below are additional safety precautions that apply to chromatography refrigerator models:
CAUTION: Equipment should only be powered using the internal outlet. In case of a leak the safety
circuit will remove power to the outlet in the unit, but shall have no control over equipment power
via battery or externally. Do not use instrumentation or equipment that incorporates potential
ignition sources, e.g. open contact switching, brushed DC and AC motors, etc.
CAUTION: The chromatography safety circuit has slots/holes at the bottom of the plug panel
for enabling air to the safety sensor. Do not block the Safety Circuit ventilation holes as this will
diminish and defeat the Safety Circuit.
WARNING: Do not store or use uncapped reagents, vessels and bottles inside the chromatography
equipment. This may diminish functionality of the safety circuit.

3. Intended Use
3. Unpacking
At delivery, examine the exterior for physical damage while the carrier’s representative is present. If exterior
damage is present, carefully unpack and inspect the unit and all accessories for damage.
If there is no exterior damage, unpack and inspect the equipment within ve days of delivery. If you nd any
damage, keep the packing materials and immediately report the damage to the carrier.
Do not return goods to the manufacturer without written authorization.
When submitting a claim for shipping damage, request that the carrier inspect the shipping container and
equipment.

4. General Recommendations
This section includes some general recommendations for your unit.
Temperature Monitoring
IMPORTANT NOTE: We recommend the use of a redundant and independent temperature
monitoring system o that the unit can be monitored continuously for performance commensurate
with the value of product stored.
Intended Use
The refrigerators described in this manual are lab-grade, general purpose units intended to store non-critical
samples at operating temperatures between 2°C to10°C.
These units are not registered as medical devices or by a medical device regulatory body (e.g. FDA): that is,
they have not been evaluated for the storage of samples for diagnostic use or for samples to be re-introduced
to the body.
This unit is not intended for use in classied hazardous locations, nor to be used for the storage of ammable
or corrosive inventory.
These refrigerators are not suitable for outdoor location.
CAUTION: Storage of unsealed corrosive substances may cause the interior of the unit to corrode.
Initial Loading
Allow the unit to operate at the desired temperature for a minimum of 12 hours before loading.
Load the unit one shelf at a time, starting from bottom to top shelf. After loading each shelf, allow the unit to
recover to the desired set point before loading the next shelf. Repeat this process until the unit is fully loaded.
Refer to the section Shelves for shelf load ratings.
CAUTION: Failure to follow these procedures or overloading the unit may cause undue stress on the
compressors or jeopardize user product safety.

5. Operating Standards
The units described in this manual are classied for use as stationary equipment in a Pollution Degree 2 and
Over voltage Category II environment.
These units are designed to operate under the following environmental conditions:
• Indoor use
• Altitude up to 2000 m (6512 feet)
• Maximum relative humidity 60% for temperatures from 15°C to 32°C (59°F to 90°F)
• Main supply voltage uctuations not to drop or exceed by 10% of the nominal voltage
• Do not connect the unit to a GFCI (Ground Fault Circuit Interrupter) protected outlet as it may be subject to
nuisance tripping
• Do not run this unit o the extension cords
Unit Specications
The data label is located on the left side on top towards front of the unit.
The specications of refrigerator like voltage, required wall breaker amperage and power plug are same for all
the units.
Voltage = 115V / 60Hz
Amps - Refer to data label for unit rating. The power supply cord plug indicates the WLL circuit breaker rating
at 15A.
Chromatography Power Plug = NEMA 5-15P
General Purpose Refrigerator Power Plug = NEMA 5-15P
This plug must be plugged into/supplied with it's own individual branch circuit.
CAUTION: Chromatography units are supplied with two separate power cords. Be careful to unplug
both during movement, testing or repair of the product.
Other specications are listed in the table below.
