General Recommendations
Temperature Monitoring
IMPORTANT NOTE: Thermo Fisher Scientific recommends the use of a redundant and independent temperature monitoring system so that the freezer can be monitored continuously for performance commensurate with the value of product stored.
Battery Door Opening /
Closing
To open the grille door, pull the door from the top right corner as shown in the figure below.
To close the grille door, push the door against frame to hold latch in position.
General Usage
This refrigeration system is designed to maintain ultra-low temperatures with safety in an ambient environment within
15°C to 32°C (59°F to 90°F), only when the freezer is used for storage.
WARNING:
This unit is not a “rapid-freeze” device. Freezing large quantities of liquid, or highwater content items, will temporarily increase the chamber temperature and will cause the compressors to operate for a prolonged time period.
Figure 1. Door Opening
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.
Initial Loading
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 set point 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.

Super Insulated Cabinet
Construction
In all models, the cabinet walls have a vacuum insulation core encapsulated by a sealed film laminate.
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.
CAUTION: 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% of the freezer rated voltage.
CAUTION:
Never drill holes in or near the cabinet walls. Drilling could damage the insulation and make the unit inoperable.
Door Operation
Upright freezer models are equipped with an advanced assembly specifically designed for ultra-low temperature freezers.
Features include:
• One-hand operation
• A front-accessible lock
• Hasps for a standard padlock to provide additional security. Length of the shackle must be between 3/4"
(1.9 cm) and 1 1/2" (3.8 cm)
• Durable construction for reliable operation and safe product storage
6 | Installation Thermo Fisher Scientific ULT Freezers
• Door ramp alignment feature
CAUTION:
When moving the freezer, always grasp cabinet surfaces; never pull the freezer by the latch handle.
Opening the Door
1. Remove the padlock if installed.
2. Grasp the latch handle and pull it toward yourself until the latch disengages.
3. Keep pulling by the latch handle to open the main door.
Installing the Remote
Alarm Connector
The remote alarm contacts are located on the back of the freezer above and to the left of the power switch. After installing the wiring from the remote alarm to the connector, install the connector to the freezer micro-board.
The pin configuration is shown in Figure 2 below.
Closing the Door
Note:
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 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.
3. Keep applying gentle pressure to the latch handle until the latch is securely in closed position.
4. Insert the key and rotate counterclockwise to lock.
5. Replace the padlock as required.
Figure 2. Remote Alarm Pin Configuration
For systems that alarm in closed state, connect to pins 5 & 6.
For systems that alarm in open state, connect to pins 6 & 7.
The contacts will trip in the event of a power outage, high temperature alarm, low temperature alarm or door ajar alarm.
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, in extreme cases, several hours 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 door behind the eye-level panel on the front of the freezer. Although the port is heated and designed to selfdefrost, excessive frost accumulation on the inner door could eventually restrict air flow. Therefore, you should periodically inspect the inner door and brush away any loose frost using a stiff nylon brush.

Gasket Maintenance
Periodically check the gaskets around the door for punctures or tears. Leaks are indicated by a streak of frost which forms at the point of gasket failure. Make sure that the cabinet is level (refer
Keep the door gaskets clean and frost free by wiping gently with a soft cloth.
Battery Maintenance
The freezer monitors the voltage status of the battery daily and indicates the battery’s voltage via visual and auditory alarm. Replace the battery as indicated by system alarms or as necessary per individual status evaluation. Check the battery connections regularly. Although not required, annual battery replacement is recommended to ensure proper battery status in the event of power failure.
For safety, it is recommended to power off the unit and disconnect it from the power source before replacing the battery. Battery terminals are color coded in red and black.
Ensure the corresponding colored wires are connected to the matching color terminals on the battery. The battery is installed with terminals oriented toward the condenser compartment or hinge side of the freezer’s outer door (refer
). With proper installation, the red wire should be connected to the rear battery (positive) terminal and the black wire to the front (common) terminal.
Failure to properly connect the battery can damage electrical components and potentially hinder normal operation of the freezer. Consult a certified service technician if there are any questions or concerns about battery maintenance.
