1 About Ultra-Low Temperature Freezers
All of the ultra-low temperature freezers described in this manual
feature a combination of advanced technologies designed
specifically to provide optimal reliability in low-temperature
applications.
Ultra-low systems include:
• DuPont Suva
®
refrigerants selected to provide maximum
cooling capacity under low-temperature conditions
• A field-proven cascade refrigeration system design.
All upright models include a pressure equalization port to combat
the vacuum created after door openings.
2 Safety Precautions
In this manual and on labels attached to this product, the words
WARNING and CAUTION mean the following:
• WARNING: a potentially hazardous situation which, if not
avoided, could result in serious injury or death.
• CAUTION: a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury or damage to
the equipment.
Before installing, using or maintaining this product, please be sure
to read this manual and product warning labels carefully. Failure to
follow these instructions may cause this product to malfunction,
which could result in injury or damage.
Below are important safety precautions that apply to this product:
• Use this product only in the way described in the product
literature and in this manual. Before using it, verify that this
product is suitable for its intended use.
• Do not modify system components, especially the controller.
Use OEM exact replacement equipment or parts. Before use,
confirm that the product has not been altered in any way.
• Your unit must be properly grounded in conformity with
national and local electrical codes. Never connect the unit to
overloaded power sources.
• Disconnect the unit from all power sources before cleaning,
troubleshooting, or performing other maintenance on the
product or its controls.
The following symbols are used in caution, warning and
informational labels attached to the freezer:
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 five days of delivery. If you find 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.

Thermo Scientific Revco PLUS Upright Freezers Installation and Operation
4 General Recommendations
This refrigeration system is designed to maintain ultra-low
temperatures with safety in a +32°C (90°F) ambient
environment, only when the freezer is used for storage.
WARNING! This unit is not a “rapid-freeze” device.
Freezing large quantities of liquid, or high-water
content items, will temporarily increase the chamber
temperature and will cause the compressors to
operate for a prolonged time period.
Avoid opening the door for extended time periods since chamber
temperature air will escape rapidly. Also, keep the inner doors
closed as much as possible. When room air, which is higher in
humidity, replaces chamber air, frost may develop in the chamber
more rapidly.
4.1 Initial Loading
After reading and completing the Safety Considerations,
Pre-Installation, Installation, and Operation sections of this
manual, start up the freezer following the instructions in
Section 8.1 on page 5.
Allow the freezer to operate at the desired temperature for a
minimum of 12 hours before loading.
Load the freezer one shelf at a time, beginning with the top shelf.
After loading each shelf, allow the freezer to recover to the
desired setpoint before loading the next shelf. Repeat this process
until the freezer is fully loaded.
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 freezers described in this manual are classified for use as
stationary equipment in a Pollution Degree 2 and Overvoltage
Category II environment.
These units are designed to operate under the following
environmental conditions:
• Indoor use
• Altitude up to 2000m
• Maximum relative humidity 60% for temperatures
up to 32ºC (90ºF)
• Main supply voltage fluctuations not to exceed 10% of the
nominal voltage.
6 Installation
Do not exceed the electrical and temperature ratings printed on
the dataplate located on the lower left side of the unit.
CAUTION! Improper operation of the equipment
could result in dangerous conditions. To preclude
hazard and minimize risk, follow all instructions and
operate within the design limits noted on the dataplate.
6.1 Location
Install the unit in a level area free from vibration with a minimum
of five inches of space on the top and back, eight inches on each
side. Refer to Section 6.3 for further instructions on leveling
cabinets. Allow enough clearance so that door can swing open at
least 90 degrees.
Do not position the equipment in direct sunlight or near heating
diffusers, radiators, or other sources of heat. The ambient
temperature range at the location must be 59 to 90°F
(15to32°C).
CAUTION! To allow for proper air flow, a minimum
of six inches of clearance space is required on the
sides, top and rear of the freezer.
6.2 Wiring
CAUTION! Connect the equipment to the correct
power source. Incorrect voltage can result in severe
damage to the equipment.
CAUTION! For personal safety and trouble-free
operation, this unit must be properly grounded before
it is used. Failure to ground the equipment may cause
personal injury or damage to the equipment. Always
conform to the National Electrical Code and local
codes. Do not connect the unit to overloaded power
lines.
CAUTION! Do not position the unit in a way that
impedes access to the disconnecting device or circuit
breaker in the back of the unit.
Always connect the freezer to a dedicated (separate) circuit. Each
freezer is equipped with a service cord and plug designed to
connect it to a power outlet which delivers the correct voltage.
Supply voltage must be within +10% or -10% of the freezer rated
voltage.
CAUTION! Never cut the grounding prong from the
service cord plug. If the prong is removed, the
warranty is invalidated.
6.3 Leveling
Make sure that the floor is level. The unit must be level both
front to back and side to side.
