The Shuttle model ULT25NE (Ultra-Low Temperature, 25 liter volume) incorporates next

generation free-piston Stirling engine technology. Free-piston Stirling engine technology

diﬀers from conventional compressor-based refrigeration in that it provides high eﬃciency,

deep-temperature cooling in a lightweight package allowing true portable operation.

1. Safety Precautions

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 -86ºC 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.

*Warning: Unauthorized modication to the cabinet, controls or free-piston Stirling engine is prohibited

and will void all warranty provisions.

1.2 – Damage Prevention

• Do not disassemble, modify or repair. There are no user serviceable parts inside

the freezer unit.*

• Do not immerse in water or pour water on the unit.*

• Do not put ice or liquid water directly in the freezer box, always use suitable

containers.

• Do not use glass containers when the contents might freeze and break.

• Do not store ﬂammable items such as gasoline, thinner or solvents in the freezer.

The freezer is NOT rated as an explosion-proof freezer.

• Do not use hard and/or sharp objects, such as knives, screwdrivers, etc. to remove any

frost or ice which has accumulated on the inside of the freezer. The inside panels are

heat exchangers and can be damaged.

• Do not block the air intake or air discharge vents.

• Do not drop, throw or abuse the freezer.*

• Do not operate under extreme environmental conditions, such as in a car trunk,

in very high humidity environments, in rain or other severe weather.*

• Do not use solvents to clean the control panel or the outside or inside of the freezer.

1.3 – Transportation Care

• Only ship via ground transportation to ensure proper unit function (especially import-

ant for domestic addresses).

• Use only factory-provided packaging. If unavailable, contact the manufacturer for

replacement packaging materials.

• Do not place unit on sides or turn upside down.

*Warning: Unauthorized modication to the cabinet, controls or free-piston Stirling engine is prohibited

and will void all warranty provisions.

1. Safety Precautions

8 of 28 Operating Manual: ULT25NE 10327.1 | 12.22.2016

A. To use the AC Power Supply:

i. During 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 Shuttle.

B. To use the DC Power Cord in a motor vehicle:

i. Make sure the freezer remains level. Exceeding an

angle of 12 degrees may cause loss of cooling.

ii. Plug the DC Power Cord into a 12V outlet that is

rated at 20 amps.

NOTE: Not for use with 24 volt automotive systems.

20 A DC REQUIREMENT: Consult your automotive

specialist if your vehicle lacks 20 A rated 12V 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 clockwise until an audible

“click” indicates full connection.

2. Unpacking and Set-Up

1. Remove the freezer and all accessories from the box. Carefully inspect

the freezer and all accessories for any shipping damage.

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

3. Ensure the access port stopper or sealant is in place. Remove factory tape at the

port stopper prior to initial use.

4. Place the freezer on a level surface.

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

6. 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.

7. 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 12V 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 20 A DC service is required for

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

be equipped with 20 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.

8. Disconnecting from power.

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

i. The LCD display will show the word“OFF”while the Shuttle

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.
