Information about the used refrigerants

The Regulation (EU) No. 517/2014 on fluorinated greenhouse gases applies to all

systems which contain fluorinated refrigerants and replaces (EC) 842/2006.

The aim of the Regulation is to protect the environment by reducing emissions of fluorinated

greenhouse gases.

Among other things it regulates the emission limits, use and recovery of these substances. It

also contains requirements for operators of systems which require / contain these

substances to function.

Under Regulation 517/2014, the operator of a system of this nature has the following duties:

•The operator must ensure that the equipment is checked at regular intervals for leaks.

•These intervals depend on the CO2equivalent of the system. This is calculated from

the refrigerant fill volume and type of refrigerant. The CO2equivalent of your system is

shown on the model plate.

•The operator undertakes to have maintenance, repair, service, recovery and recycling

work carried out by certified personnel who have been authorized by JULABO.

•All such work must be documented. The operator must keep records and archive them

for at least five years. The records must be submitted to the relevant authority on

request.

Refer to the text of the Regulation for further information.

4. Safety notes for the user

4.1. Explanation of safety notes

In addition to the safety warnings listed above, warnings are posted

throughout the manual. These warnings are designated by an exclamation

mark inside an equilateral triangle. “Warning of a dangerous situation

(Attention! Please follow the documentation).”

The danger is classified using a signal word.

Read and follow these important instructions.

Warning

Describes a possibly highly dangerous situation. If these instructions are not

followed, serious injury and danger to life could result.

Caution:

Describes a possibly dangerous situation. If this is not avoided, slight or minor

injuries could result. A warning of possible property damage may also be

contained in the text.

Notice:

Describes a possibly harmful situation. If this is not avoided, the product or

anything in its surroundings can be damaged.

4.2. Explanation of other notes

Note!

Draws attention to something special.

Safety notes for the user

4.3. Safety instructions

Follow the safety instructions to avoid personal injury and property damage. Also,

the valid safety instructions for workplaces must be followed.

•Only connect the unit to a power socket with an earthing contact (PE –

protective earth)!

•The power supply plug serves as a safe disconnecting device from the

line and must always be easily accessible.

•Place the unit on an even surface on a base made of nonflammable

material.

•Do not stay in the area below the unit.

•Make sure you read and understand all instructions and safety

precautions listed in this manual before installing or operating your unit.

•Do not touch the immersion probe if it is frosted.

•Do not bend the tube connection of the immersion probe

•Keep the air intake and exhaust grids free of obstructions. (Maintain a

sufficient distance from all surrounding surfaces!)

•Do not move the unit from the position where it was set up during

operation.

•Always turn off the unit and disconnect the mains cable from the power

source before performing any service or maintenance procedures, or

before moving the unit.

•Always turn off the unit and disconnect the mains cable from the power

source before cleaning the unit.

•Transport the unit with care.

•Sudden jolts or drops may cause damage in the interior of the unit.

•Observe all warning labels.

•Never remove warning labels.

•Never operate units with damaged mains power cables.

•Repairs are to be carried out only by qualified service personnel.

•There are thermal dangers: Touchable parts of the probe can be very

cold. Therefore, exercise particular caution when touching these parts.

Use gloves.

5. Preparations

5.1. Installation

•Place the unit on an even surface on a pad made of non-

flammable material.

•Press down the castor levers on model FT900.

•The instrument should be set up at a frost-proof and dry location.

•The place of installation should be large enough and provide

sufficient air ventilation to ensure the room does not warm up

excessively because of the heat the instrument rejects to the

environment. (Max. permissible ambient temperature: 35 °C).

For a fault (leakage) in the refrigeration system, the standard EN

378 prescribes a certain room space to be available for each kg of

refrigerant.

> For 0.25 kg of refrigerant R134a, 1 m3 of space is required.

> For 0.52 kg of refrigerant R404A, 1 m3 of space is required.

> For 0.68 kg of refrigerant R23, 1 m3 of space is required.

•The ambient temperature must not exceed 35 °C.

•Keep at least 20 cm of open space on the front and rear venting

grids.

•Do not set up the unit in the immediate vicinity of heat sources and

do not expose to sun light.

•Before operating the unit after transport, wait about one hour after

setting it up. This will allow any oil that has accumulated laterally

during transport to flow back down thus ensuring maximum cooling

performance of the compressor.

5.2. Immersion Probe

Avoid touching the immersion probe if it is frosted.

DANGER OF INJURY. Use gloves.

Switch the unit on only if the probe is immersed into the bath fluid.

To prevent the immersion probe (A) from icing, it should be completely

immersed into the bath liquid (B).

Recommended flow rate: 2 to 3 l/min

6. OPERATING PROCEDURES

6.1. Power connection

Caution:

•Only connect the unit to a power socket with earthing contact (PE –

protective earth)!

•The power supply plug serves as safe disconnecting device from the line

and must be always easily accessible.

•Never operate equipment with damaged mains power cables.

•Regularly check the mains power cables for material defects (e.g. for

cracks).

•We disclaim all liability for damage caused by incorrect line voltages!

Make sure that the line voltage and frequency match the supply

voltage specified on the type plate.

Deviations of ±10 % are permissible.

6.2. Switching On

•The immersion cooler is turned on and off with the mains switch.

(1).

The control light in the switch will illuminate.

The immersion probe – as part of the cooling circuit – should not be exposed

to bath temperatures above the working temperature of the immersion cooler.

This would cause damage to the compressor.

Do not immerse a frosted immersion probe into hot bath oil.
