1 About Legaci®
All of the Revco ultra-low temperature freezers described in this
manual feature the Legacirefrigeration system, a combination
of advanced technologies designed specifically to provide
optimal reliability in low-temperature applications.
Legaci systems include:
•Copeland compressors custom-designed for Revco to
minimize bearing wear and operate efficiently under heavy
work loads
•Dupont Suvarefrigerants selected to provide maximum
cooling capacity under low-temperature conditions
•Revco’s 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.
3 General Recommendations
The 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. Attempting to
utilize this freezer improperly may jeopardize safety or
cause undue stress or damage to the refrigeration
compressors.
Avoid opening the door for extended time periods since chamber
temperature air will escape rapidly. Room air, which is higher in
humidity, replacing chamber air may cause frost to develop in the
chamber more rapidly.
After reading and completing the Safety Considerations,
Pre-Installation, Installation, and Operation sections of this
manual, turn the Key Switch to the POWER ON position.
3.1 Initial Loading
When loading the unit with “pre-frozen” materials, the operating
temperature setpoint of the freezer should be set no lower than
the temperature of the “pre-frozen” material. Allow the unit to
operate at the setpoint for eight hours. The setpoint may then be
lowered in increments no greater than 10ºC. Allow a stabilizing
period of eight hours for each ten degree adjustment, until the
desired setpoint is achieved.
CAUTION! Failure to follow these procedures or
overloading the unit may cause undue stress on the
compressors or jeopardize user product safety.
4 Pre-Installation
4.1 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 Revco without written
authorization. When submitting a claim for shipping damage,
request that the carrier inspect the shipping container and
equipment.
CAUTION! Do not discard the sublids from
chest-style units. The sublids are necessary to
maintain correct temperature, moisture control, and
economy of operation. Upright models do not include
sublids as they utilize built-in metal inner doors.

5 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.
5.1 Location
Install the unit in a level area free from vibration with a minimum
of six inches of space on the sides, rear, and top. Refer to
Section 5.3 for further instructions on leveling cabinets. Allow
enough clearance so that door or lid 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
(15 to 32C).
CAUTION! To allow for proper air flow, a minimum
of six inches of clearance space is required behind the
freezer.
5.2 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.
Your freezer is equipped with one of five NEMA style plugs
(refer to Figure 1). These plugs meet UL requirements.
Figure 1. NEMA Style Plugs
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%, -5% of the freezer rated
voltage.
If you have known voltage stability problems which are outside
the limits of the freezer rated voltage, we recommended that the
freezer be equipped with a Voltage Safeguard. Order the Voltage
Safeguard from Revco (refer to Section 10.1.3 on page 12 for
ordering information).
Note: Revco 900 Series freezers are equipped with a standard
built-in Voltage Safeguard circuit to detect and adjust
low line voltage.
CAUTION! Never cut the grounding prong from the
service cord plug. If the prong is removed, the
warranty is invalidated.
5.3 Leveling
The unit must be level both front to back and side to side.
To level chest models, leave the casters in place and shim the low
wheel(s) with strips of sheet metal cut at least 1/2 in. wider than
the caster.
Upright models have adjustable leveling feet which are located
adjacent to the front casters.

substantial prying forces on the door.
3. Keep applying gentle pressure to the latch handle until the
latch is securely in closed position.
4. Insert the key and rotate clockwise to lock.
5. Replace the padlock if you are using one.
5.5 Pressure Equalization Port
When an upright ultra-low temperature freezer door is opened,
room temperature air rushes into the storage compartment. 
When the door is closed, the fixed volume of air is cooled rapidly.
Pressure drops below atmospheric pressure, resulting in a
substantial vacuum. Re-entry into the cabinet is impossible until
internal pressures are returned to atmospheric pressure. Without a
pressure equalization mechanism, it can take several minutes
before the door can easily be reopened.
All upright models feature a port that provides vacuum relief
after door openings.
The pressure equalization port is located in the bottom left side of
the storage chamber. Although the port is designed to self-
defrost, excessive frost accumulation in the bottom of the
chamber could eventually restrict air flow. Therefore you should
periodically inspect the port and brush away any loose frost using
a stiff nylon brush.
WARNING! To ensure proper operation, be sure not
to obstruct the port. Push any storage racks near the
port all the way to the rear of the cabinet.
WARNING! When the freezer is in operation, avoid
touching the lower left side of the cabinet exterior near
the “hot surface” warning label. The port can get hot
immediately after it is activated.

6.3.1 CO2and LN2Precautions
The following are precautions for using liquid CO2and LN2
backup systems.
WARNING! If a CO2or LN2cylinder falls and a
valve is knocked off, the cylinder becomes a deadly
and completely unguided missile. Transport the
cylinders in a handtruck or cart with secure chain ties
for the cylinder. After cylinders are connected to the
equipment, securely attach them with chains to a
solid, stationary object such as a building column.
WARNING! CO2and LN2liquids are non-poisonous
but are very cold and will burn unprotected skin.
Always wear protective eyewear and clothing when
changing cylinders or working on the piping systems
attached to an active source of liquid refrigerant.
WARNING! The gases produced by evaporation of
CO2or LN2are non-poisonous but displace the
oxygen in a confined space and can cause
asphyxiation. Do not store the cylinders in subsurface
or enclosed areas.
CAUTION! When closing the cylinder valve, make
sure that the injection solenoid is energized to allow all
the liquid to bleed off instead of being trapped in the
supply tubing. Failure to do this results in activation of
the pressure relief device, which could damage the
freezer and requires replacing if it is activated.
CAUTION! For chest and upright models ordered
with factory installed built-in backup systems, the flow
of liquid CO2or LN2will be discontinued if the door or
lid is opened during operation of the backup system.
For units operated with free-standing, field installed
type backup system, the flow of liquid CO2or LN2will
be discontinued upon door or lid opening only if the
switch provided with the free-standing package is
installed on the freezer.

retains calibration even during power interruptions. If required,
however, adjustments can be made as follows:
1. Run the unit continuously at the control setpoint temperature.
Continue steady operation for at least two hours to provide
adequate time for recorder response.
2. Measure cabinet center temperature with a calibrated
temperature monitor.
3. Compare the recorder temperature to the measured cabinet
temperature. If necessary, adjust recorder by pressing the left
(#1) and right (#2) chart buttons.
Note: The stylus does not begin to move until the button is held
for five seconds.

10 Optional Equipment
In addition to the optional chart recorder, the following
equipment is available for some freezer models. Refer to the
Accessories section on page 12 for more information on these
and other options, including inventory racks and storage boxes.
For additional information, contact your Revco dealer or Revco
Customer sales at 1-800-252-7100.
10.1 Backup Protection Devices
Liquid Nitrogen and Liquid CO2systems are available to protect
your product in case of a prolonged power failure. These systems
are powered by a rechargeable battery with a built-in automatic
charger. Refer to Section 6.3.4 on page 7 for additional
information.
10.1.1 Liquid Nitrogen (LN2)
This system uses portable and locally refillable bottles. These
containers keep the liquid at low temperature and pressure by
continually venting a small amount of gaseous N2. You must
check the liquid level indicator daily to assure an adequate
emergency supply.
10.1.2 Liquid CO2
This system uses portable and locally refillable bottles that are
not vented and have a virtually unlimited standby life unless they
develop a leak. These containers hold liquid at room temperature
and high pressure. Several bottles can be connected together,
increasing the effective length of standby refrigeration.
10.1.3 Voltage Safeguard
This fully automatic device monitors the supply voltage and
increases voltage if necessary so the freezer always operates
within the factory recommended limits. Ultima II models are
factory equipped with this device.
CAUTION! The Voltage Safeguard unit does not
allow you to operate a 115 volt product on 230 volts or
vice versa. It is designed to provide 5 to 15% voltage
correction, depending on the freezer model.
10.2 Remote Alarm
The remote alarm terminals on the back of the freezer are
connected to freezer internal dry contacts. You can connect a
remote alarm package with a separate 24 volt power supply.
