To prevent personal injury, injury to others, or damage to property,

read these safety precautions carefully before use.

1.1 INJURY PREVENTION

Do not cut change or modify the power cable*

When removing the plug hold onto the plug and not the cord

An ultralow temperature freezer is qualitatively different than a home freezer

At ºC frostbite can occur instantly

The user should establish and follow a protocol for safe ultralow temperature

operating procedures This should include (but not limited to)

>Never handle samples or freezer accessories with bare hands

>Do not use gloves which become brittle at ultralow temperatures

>Nitrile and latex gloves are inadequate

Permeable gloves are dangerous because ultralow temperature materials

can contact skin and cause damage

>Be especially careful that materials at ultralow temperature are not spilled

onto skin or clothing

>Use only sample containers that have been approved or tested for ultralow

temperature use

>Some plastics shatter at ultralow temperatures Avoid splinter hazards

>Biological and chemical hazards are still hazardous at ultralow temperature

Always wear proper protective equipment and follow appropriate

isolation protocols

>Many types of labels will fall off and/or break at ultralow temperature

Some types of ink which stick to glass and/or plastic at room temperature

lose adhesion at ultralow temperature

In addition to the ultralow temperature hazards above there are also physical

hazards to consider

>Be cautious when closing the lid to avoid a pinching hazard

>Be careful when loading the box with heavy items

>Always use the handles to carry the freezer

2. UNPACKING AND SETUP

Remove the freezer and all accessories from the box. Carefully

inspect the freezer and all accessories for any shipping damage.

Check the packing list to verify that the shipment is complete.

Ensure the access port stopper or sealant is in place.

Place the freezer on a level surface.

Make sure that the air inlets and outlets are not blocked.

 Connect to a power source. While the freezer can be used

with either the AC Power Cord for lab, home or office use,

or the DC Power Cord for mobile use, it is recommended that

the initial pull-down to Setpoint be completed via AC power.

A To use the AC Power Supply

iDuring setup identify the service power and

plug conﬁguration available and then locate

the appropriate line cord for the service type

you will be using

ii If the appropriate line cord is not currently installed

simply unplug the line cord from the unit and then

plug the appropriate line cord in its place

iii Plug the other end of the line cord into the power

source and then attempt to power on the unit

B To use the DC Power Cord in a motor vehicle

iMake sure the freezer remains level Exceeding

an angle of  degrees may cause loss of cooling

ii Plug the DC Power Cord into a V outlet that is

rated at  amps NOTE Not for use with  volt

automotive systems

NOTE Not for use with  volt automotive systems

 A DC REQUIREMENT Consult your automotive

specialist if your vehicle lacks  A rated V outlets

iii Plug the opposite end into the freezer Slide the male line cord adapter

into the female connection port lining up the two plastic bungs on

the male adapter with the cutouts in the female port of the freezer

Press the male adapter ﬁrmly into the connection port and turn

 Notes on operation in a vehicle.

A The freezer will operate on vehicle battery power for a limited time before

the battery is drained and the motor vehicle cannot be started This time

will vary from vehicle to vehicle but is generally only a few hours

B The vehicle engine should be running to prevent accidental total discharge

of the battery

C The power to V outlets in some vehicles may be interrupted during engine

starting This will cause a sudden stop of the cooling unit which may produce

a sound that is different than when turning off the freezer by using the

On/Off button This is normal and will not damage the cooling engine

The cooling engine will restart automatically once power resumes

D 20 A DC REQUIREMENT: Please note that  A DC service is required for

proper functioning of the freezer in a motor vehicle Some vehicles may not

be equipped with  A DC service Consult your automotive specialist to

verify the level of DC service installed in your vehicle

E Do not operate the freezer in an unattended vehicle This may lead to

overheating if left in the sun and subsequent damage to stored contents

 Disconnecting from power.

A Turn off the freezer (Press and hold On/Off button for three beeps)

iThe LCD display will show the word “OFF” while the unit turns off

ii Unplug the freezer after the word “OFF” disappears and the display

goes dark

iii If you unplug the freezer while it is on you will hear a sudden noise as

the freepiston Stirling engine shuts off Power outages will also cause the

same noise This noise (described as a “bonk”) is not indicative of damage
