General Recommendations

6 Installation and Operation Thermo Fisher Scientific Ultra Low Temperature

5 General

Recommendations

5.1 Temperature

Monitoring

IMPORTANT NOTE We recommend 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.

5.2 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 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.

5.3 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.

WARNING: Do not exceed the electrical rating printed on the data plate

located on the lower left side of the unit.

7.1 Location Install the unit in a level area free from vibration with a minimum of 8 inch

(20 cm) of space on the top and sides, 6 inch (15 cm) in back. Refer to

Section 7.3 for further instructions on leveling cabinets. Allow enough

clearance so that door can swing open at least 85°.

The rear spacing posts provided with the freezer can be used to ensure

proper clearance. To install the spacing posts, screw them into the back in

the rear deck area.

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 15°C to 32°C (59°F to 90°F).

7.2 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.

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 remove or disable the grounding prong from the service

cord plug. If the prong is removed, the warranty is invalidated.

Installation

7.3 Leveling Make sure that the floor is level. The unit must be level both front to back

and side to side.

400 box capacity models are equipped with one leveling leg on the right

hand side. These may be used to help prevent the unit from shifting during

a door opening.

Be certain to lock the brakes for units equipped with casters.

7.4 Backup System

(Optional) If you are using a CO2 or LN2 backup system, refer to Section 11 for

installation and operation instructions.

7.5 Super Insulated

Cabinet Construction In all models, the cabinet walls have a vacuum insulation core encapsulated

by a sealed film laminate.

CAUTION: Never drill holes in or near the cabinet walls. Drilling could

damage the insulation and make the unit inoperable.

7.6 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 should be between 3/4 inch (1.9 cm) and 11/2 inch (3.8 cm).

• Durable construction for reliable operation and safe product storage.

• Door ramp alignment feature

• Optional controlled access to the freezer with Proximity Access cards.

CAUTION: When moving the freezer, always grasp cabinet surfaces; never

pull the freezer by the latch handle.

7.6.1 Opening the Door For freezers with the Proximity Access Card option:

1. Remove the padlock if installed.

Installation

12 Installation and Operation Thermo Fisher Scientific Ultra Low Temperature

7.7 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 designed to

self-defrost, 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.

7.8 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.

Figure 2. Remote Alarm Pin Configuration

The contacts will trip in the event of a power outage, high temperature

alarm, low temperature alarm or door ajar alarm.
