General Recommendations

6 Installation and Operation Manual Thermo Scientific Ultra Low Temperature Freezers

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 up to +32°C (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.

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 59 to 90°F (15 to 32°C).

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% 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.

Installation

Thermo Scientific Ultra Low Temperature Freezers Installation and Operation Manual 9

7.3 Leveling

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

side to side.

300 and 400 box capacity models are equipped with two leveling legs on the

right hand side. These must be lowered to ensure stability of the unit.

Be sure to set the brakes for units equipped with casters.

7.4 Backup System

(Optional)

If you are using a CO

2

or LN

2

backup system, refer to

Section 11

for installation

and operation instructions.

7.5 Superinsulated

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.

designed for ultra-low temperature freezers.

Features include:

• One-hand operation

• A front-accessible lock

• Hasps for a standard padlock to provide additional security

• Durable construction for reliable operation and safe product storage

• 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.

Installation

10 Installation and Operation Manual Thermo Scientific Ultra Low Temperature Freezers

7.6.1 Opening the Door

For freezers with the Proximity Access Card option:

1. To unlock the door, pass the card in front of the freezer below the LCD

display.

2. Grasp the latch handle and pull it toward yourself until the latch

disengages from the cabinet strike.

3. Keep pulling by the latch handle to open the main door.

For freezers without the Access Card option:

1. Remove the padlock if installed.

2. Grasp the latch handle and pull it toward yourself until the latch

disengages from the cabinet strike.

3. Keep pulling by the latch handle to open the main door.

7.6.2 Opening the Door During

a Power Outage

In case of power outage, you may use a 9 volt battery to activate the proximity

card access system. To access the 9 volt terminal, a piece of plastic trim must be

removed near the user interface.

If the trim is gray, remove the left plastic trim by sliding it up and gently pulling

it out.

If the trim is blue, slide the U-shaped trim piece down and gently pull it out.

Once the terminal is exposed, you can open the door by holding the 9 volt

battery against the terminal and passing a valid proximity card below the display

area.

Once the door is open, remove the battery.

7.6.3 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 (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.

Installation

Thermo Scientific Ultra Low Temperature Freezers Installation and Operation Manual 11

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.

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.
