Installation and Operation 

Chest and Upright Freezers 

4 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, tum the Key Switch to the POWER ON position. 

4.1 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 10°C. 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.

Your freezer is equipped with one of five NEMA style plugs 

(refer to Figure 1). These plugs meet UL requirements. 

v = . 

15A-125V 20A-125V 15A-250V 20A-250V 30A-250V 

NEMA 5-15P NEMA 5-20P NEMA 6-ISP NEMA 6-20P NEMA 6-30P 

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 12.1.3 on page 13 for 

ordeting information). 

Note: Revco Ultima 700 and 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. 

6.3 Leveling 

The unit must be le~el 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 

adj a cent to the front casters. 

6.4 Door Operation {Upright Models) 

Revco upright freezer models are equipped with an advanced 

Cryolatch TM assembly specifically designed for ultra-low 

temperature freezers. 

Features include: 

• One-hand operation 

• A front-accessible lock, keyed to match the freezer control 

lock 

• Hasps for a standard padlock to provide additional security 

• Durable construction for reliable operation and safe product 

storage. 

CAUTION! When moving the freezer, always grasp 

cabinet surfaces; never pull the freezer by the latch 

handle. 

6.4. 1 Opening the Door 

Installation and Operation 

Chest and Upright Freezers 

1. Remove the padlock if you have one. 

2. Move the key into the open position by rotating it counterclockwise. 

3. Grasp the latch handle (preferably with your left hand) and 

pull it toward yourself until the latch disengages from the 

cabinet strike. 

4. Keep pulling by the latch handle or the integrated door 

handle to open the main door. 

6.4.2 Closing the Door 

Note that the latch does not self-engage automatically when you 

close the door. You must rotate the latch into the open position 

first. 

1. Grasp the latch handle (preferably with your left hand) and 

pull it toward yourself, rotating the latch into the open 

position. 

2. Move the freezer door into the closed position and gently 

push the handle away from you, making sure that the latch 

engages fully with the cabinet strike. 

CAUTION! Closing the door without making sure 

the latch engages fully with the strike can result in 

substantial prying forces on the door. 

3. Keep applying gentle pressure Jo the latch handle until the 

latch is securely in closed poition. 

4. Insert the key and rotate clockwise to lock. 

5. Replace the padlock if you are using one. 

6.5 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 front 

center 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! Because the defrost heater for the 

pressure equalization port operates continuously, the 

surfaces near the port can get hot if the unit Is plugged 

In but the freezer is not In use. You can avoid this by 

unplugging the freezer when It Is not being used for 

cold storage.

cools below the warm alarm temperature. The alarm quits 

automatically when the sensor cools below the warm alarm 

value. 

Note: There is a limit on the alarm test feature. The alarm test 

will not commence if the warm alarm setpoint is more 

than 15 degrees warmer than the operating temperature 

setpoint. 

7.3 Backup System (Optional) 

When you purchase a built-in C02 or LN2 optional backup 

system for the freezer, the backup system control panel is located 

behind a hinged panel adjacent to the grill (refer to Figure 3). 

Note: Always purchase the cylinders which are equipped with 

siphon tubes for withdrawing liquid from the bottom of 

the cylinder. C02 cylinders must be kept at room 

temperature to function properly. LN2 bottles are 

functional at any reasonable temperature. 

Use this panel to set the backup initiation temperature, usually 

10 to 15°C warmer.than the operating setpoint.

7.3.1 C02 and LN2 Precautions 

The following are precautions for using liquid C02 and LN2 

backup systems. 

WARNING! If a C02 or LN2 cylinder 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! C02 and LN2 liqulds 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 

C02 or LN2 are 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 cl0slng 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 C02 or LN2 will 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 C02 or LN2 will 

be discontinued upon door or lid opening only if the 

switch provided with the free-standing package is 

installed on the freezer.
