following instructions thoroughly and act accordingly.

The ULT Freezer Premium Line offers many unique features to enhance safety, performance

and ergonomic. To take full advantage of the features, please read this manual firmly and keep

it safe for future reference. If you are unfamiliar with how ULT Freezers operate, please review

Chapter 4: Refrigerant Safety Precautions before you start working with the ULT Freezer. Even

if you are an experienced user of ULT Freezers, please read all the user manual firmly.

1.1 Intended use.

The ULT range –86°C freezer described in this manual are high performance units for

Chapter 2: Precondition

Before you install the ULT Freezer, you need to prepare the site for installation. Examine the

location where you intend to install the Freezer. You must be certain that the area is level and of

solid construction.

In addition, a dedicated source of electrical power must be located near the installation site.

Carefully read this chapter to learn:

•Storage requirements.

•Location requirements.

•Electrical power requirements.

•Space requirements.

•Service utility requirements.

•Environment Requirement.

Storage.

If the Freezer will be stored for a period without power, the door and inner doors should be kept

open for free circulation of air inside the cabinet to avoid corrosion of the inner liner.

Environmental protection and disposal.

The packaging is designed to protect the appliance and its components during transportation,

and it is made of recyclable materials.

•Please return the packaging to an ofﬁcial collection point for recycling.

•Old appliances contain reusable materials and should not be disposed off together with

household refuse.

•Remove the spring-action hinges from the appliance, to prevent children from being entrapped in

the appliance.

•Ensure that no part of the refrigeration tubing is damaged as the refrigerant in the appliance risks

leaking to the environment.

•Information about refrigerant type and amount will be found on the Rating plate on the rear of the

appliance (Fig. 1).

minimum two people.

•If upon unpacking the appliance damage is detected, do not connect to the mains, but contact

the supplier.

•Interference with or repair to the appliance should only be carried out by authorized personnel,

to avoid any injuries. (contact the supplier for further information)

•Never use open ﬂames or other ignition sources inside the appliance.

•Never touch the Freezers interior or products in the Freezer when the Freezer is operating.

Use gloves or alike to avoid injuries (frostbite).

•Keep the key to the doors away from the appliance, and out of the reach of children.

Chapter 3: Getting Started

Connection to the mains.

•For safety reasons, the appliance must be earthed. If you are in any doubt, please contact an

authorized electrician.

•The appliance should be left OFF for 1 hour before it is connected to the mains. If the

appliance is connected before that, there is a risk of damaging the compressor.

•If for any reason the appliance is disconnected from the mains, please wait 10 minutes before

re-connecting. The electronic starting device needs this time to cool down before a safe re-

start can be made.

Before use.

•Before use, the interior of the appliance should be cleaned with a mild soap solution and

wiped off with a dry clean cloth.

NOTE! Never use any kind of solvent or other chemicals.

Setting up the Freezer.

The Freezer should not be placed where it might be splashed with water, in extreme high humidity or

in direct sunlight. Any of these factors may lead to a reduction in performance and shorten the life

span of the components. The Freezer should be placed on a horizontal level and should not be

placed close to a heating appliance or heating tubes. Allow a minimum of 50 mm (2”) clearance on

the sides, and 100 mm at the back side, to allow the heat from the compressor motor to dissipate.

Underneath the appliance there should be a gap of 15 mm approx. (1⁄2”). On a soft surface, e.g.

carpet, it may be necessary to ensure the correct distance by means of spacers.

Electrical supply.

The electrical supply should always be in accordance with the Rating label on the left side of the

cabinet or at the bottom when you open the door to the chamber.

The supply must always be in accordance with the law and regulations regarding electrical safety, if

any doubts contact your supplier.

Chapter 4: Refrigerant Safety Precautions

Refrigerant

In the ULT Freezer there are used two type of refrigerants. The cooling system is Cascade cooling.

Carefully read the below description of the refrigerants: R290 and R1150

Demand for information: Personnel working with these refrigerants mentioned above and

below must be educated to know about these safety sheets.

Field of application:

R290 is used as refrigerant in first stage of the cooling system. R290, is refrigerant grade propane, a

natural, refrigerant suitable for use in a range of refrigeration and air conditioning applications. The

use of R290 is increasing due to its low environmental impact and excellent thermodynamic

performance. It is non-toxic with zero ODP (Ozone Depletion Potential) and very low GWP (Global

Warming Potential).

R1150 (+ R290) are used in the second stage of the cooling system.

R1150 Ethylene is refrigerant grade ethylene (ethene), a natural refrigerant suitable for use in very

low temperature refrigeration applications, such as those found in LNG liquefaction processes. R1150

is non-toxic, with zero ODP (Ozone Depletion Potential) and very low GWP (Global Warming

Potential). It is a flammable refrigerant and therefore not suitable for retrofitting existing fluorocarbon

refrigerant systems.

If needed, ask for safety data sheet from your supplier.

Chapter 5: Using the ULT Freezer

Startup process.

In case the compressors do not start when the Freezer has been plugged in, the electrical

supply may not be in order. Check if there is an electricity supply to the plug or if the fuse is

blown.

Before starting the unit, you must check and decide below parameters:

1. SET TIME: Must change to local time zone.

2. SET TEMP: Change the set point for the desired temperature in the chamber.

3. ALARMS: Change High and Low temperature alarm level.

4. ALARM DELAY: Change the time delay from the temperature reach High or

Low Temperature alarm level, to the alarm will be activated.

5. DOOR OPEN ALARM: Enable the door open alarm and the delay for the alarm will be

activated.

During the Freezer is starting up from Ambient level (RT +20°C), the High Temperature alarm

will be activated several times before the temperature reach the High temperature alarm level.

Operating the Freezer

The Empty Freezer should be switched ON for cooling down the chamber, for at least 8-10

hours, prior to loading ballast into the chamber of the Freezer.

Please note: After the door has been opened, there will be a vacuum created inside the Freezer

due to the low temperatures. Wait a few moments before trying to reopen the door otherwise

the handle or gaskets could be damaged.
