If necessary, take safety action (e.g. gloves). - All repairs and work on the appliance may only be carried out by customer service personnel or other trained personnel. The same applies to changing the mains power cable.

- Only carry out repair and other work on the appliance when the mains plug has visibly been disconnected.

- Only install, connect and dispose of the appliance as described in these operating instructions.

- In the event of a fault, pull out the plug or switch off the fuse. - When disconnecting the appliance from the mains, pull on the plug. Do not pull on the cable. - Do not use the interior LED light to light the room. The interior LED light is only designed to illuminate the interior of the appliance. - Do not allow naked flames or ignition sources to enter the appliance.

Symbols on the appliance

EN

The symbol can be located on the compressor. It refers to the oil in the compressor and indicates the following danger: swallowing or inhaling can be fatal. This is only relevant for recycling. There is no danger in normal operation. Warning about inflammable substances.

A sticker to this effect may be applied to the rear of the appliance. It refers to the foampadded panels in the door and/or the housing. This is only relevant for recycling. Do not remove the sticker.

Intended use

This universal laboratory refrigerator for professional use is suitable for storing products at temperatures between 3°C and 16°C. Typical products for storage include research samples, reagents, laboratory inventory, etc. For the storage of valuable or temperature-sensitive substances or products the use of an independent, constantly monitoring alarm system is necessary. This alarm system must be designed so that each alarm status is detected immediately by an authorised person who can then take appropriate action.

Foreseeable incorrect use

Do not use the appliance for the following applications: • Storage and cooling of

- chemically unstable, inflammable or caustic substances - blood, plasma or other bodily fluids for the purposes of infusion, application or insertion into the human body.

• Use in potentially explosive atmospheres.

• Use outdoors or in areas where it is exposed to splash water or damp conditions. Incorrect use of the appliance will result in damaging or spoiling the goods stored in it.

Declaration of conformity

The refrigerant circuit has been tested for leaks. The appliance complies with the relevant safety regulations and EU Directives 2006/42/EG, 2014/30/EU, 2009/125/EG and 2011/65/EU.

Description of the appliance

It is essential to use these safety facilities to avoid damage to stored items. These facilities must not be deactivated or decommissioned!

Setting up

• Do not place the appliance in direct sunlight or near radiators and similar sources of heat.

• The more coolant there is in the appliance, the larger the room in which the appliance is installed must be. If the room is too small, any leak may create a flammable mixture of gas and air. For each 8 g of coolant the installation space must be at least 1 m³. Information on the coolant is on the model plate inside the appliance. • Always install the appliance directly against the wall.

Levelling the appliance

Compensate floor unevenness using the adjustable feet.

NOTICE

The appliance must be aligned horizontally and vertically. If the appliance is not level, the main body of the appliance can be deformed and the door will not close properly.

Electrical connection

Switching the appliance on and off

The permissible voltage and frequency are indicated on the type plate. The position of the type plate is shown in the section entitled Description of the appliance.

Switching the appliance on

Only operate the appliance with alternating current (AC).

EN

Connect the appliance to the mains. Display = OFF. Press

for approx. 5 seconds. Display = ON.

The socket must be properly earthed and protected by a fuse. The tripping current of the fuse must be between 10 A and 16 A.

No alarm is displayed or sounded when the appliance is switched on for the first time.

The socket must not be situated behind the appliance and must be easily accessible.

If the appliance is disconnected from the mains for a long time after it has been switched on for the first time and if the temperature inside the appliance rises above the upper alarm limit, this will be detected as a fault by the electronic control system ( flashes in the display).

Do not connect the appliance using an extension cable or extension socket. Do not use stand-alone inverters (conversion of direct current to alternating current/threephase current) or energy-saving plugs. Risk of damage to the electronic control system!

When the appliance is switched on again, this display must be reset as shown below.

Note If the values of the upper and lower alarm limit (AL and AH in the section entitled "Adjusting the alarm parameters") are set to 0, and will appear in the display during this test. Note For a realistic temperature alarm test, an additional delay time (60 minutes) applies as well as the adjustable alarm parameters AL, AH and Ad. After a door has been opened or a defrosting process, the alarm delay Ad will be extended by an additional delay time (60 minutes). This additional delay time must not be changed. This means that a temperature alarm will appear later after a door has been opened or a defrosting process than is actually set using parameter Ad.

Cleaning

WARNING Before cleaning, always disconnect the appliance from the mains. Pull out the plug or switch off the fuse. WARNING Risk of electrostatic discharge. Only clean plastic parts with a damp cloth! CAUTION Risk of damage to the appliance components and risk of injury due to hot steam. Do not use steam cleaning equipment to clean the appliance. NOTICE All surfaces in the appliance must be cleaned at regular intervals! • Clean the inside, equipment parts and outer walls with lukewarm water and a little detergent. Do not use chemical solvents or any cleaning agents containing sand or acid. • To avoid short-circuits, ensure no cleaning water penetrates into the electrical components when cleaning the appliance. • Dry all parts well with a cloth.

• The dust should be removed from the refrigeration unit and heat exchanger - metal grid at the back of the appliance - once a year. • Do not damage or remove the type plate on the inside of the appliance. It is very important for servicing purposes.

Disposal notes

The appliance contains reusable materials and should be disposed of properly - not simply with unsorted household refuse. Appliances which are no longer needed must be disposed of in a professional and appropriate way, in accordance with the current local regulations and laws.

Malfunctions

You may be able to rectify the following faults by checking the possible causes yourself: • Appliance does not function: – Is the appliance switched on? – Is the plug correctly fitted in the mains socket? – Is the fuse intact? • The temperature is not low enough: – Is the temperature setting correct (see "Setting the temperature")? – Does the separately installed thermometer show the correct reading? – Is the ventilation system working properly? – Is the appliance set up too close to a heat source? • Temperature alarm test does not work as required. – See „Alarm test“ and „Adjusting the alarm parameters“ If none of the above causes apply and you cannot rectify the fault yourself, contact the nearest customer service department stating the type designation 1, service number 2 and appliance number 3as indicated on the type plate. The position of the type plate is shown in the section entitled Description of the appliance.

Installation dimensions (mm)

There are various connection options at the back of the appliance.

Version 1

The appliance may only be connected to an external alarm device by trained personnel.

A cross-section of min. 200 cm2 is re­quired in the worktop for ventilation of the rear of the appliance.

Note The connectors are secured with screws. To remove the connectors, undo the left and right screws.

Terminating resistor When connecting several appliances via the RS485 interface, the terminating resistor must remain on the last appliance. Remove the terminating resistors from the appliances in between.

Floating alarm output

These three contacts can be used to connect the appliance to an optical or acoustic alarm device. The connection is designed for a maximum of 42 V/8 A DC from a safety extra-low voltage (SELV) source (minimum current: 150 mA).

Notice

When supplying mains voltage to the floating alarm contact, the technical safety requirements of standard EN 60335 will not be satisfied.
