5.1. Installation

• Place the uni t on an ev e n s urface on a pad ma de o f non- flammable material.

• The place o f ins tal l a ti o n sh ould be large eno ug h and provide excessively because of the heat the instrument radiates to

the envir onment. (Max. permi s si bl e am bi e nt temperature: 40 °C). With regar d to a disturbance in the cooling loop (leakage), the guideline EN 378 prescribes a certain room space to be available for each kg of refrigerant. The necessary amount of refrigerant is specified on the type plate. > For 0.52 kg of refrigerant R404A, a room spac e o f 1 m required.

• Keep at least 20 cm of open space on the fron t an d re ar venting gr i d.

• Do not set up the unit in the immediate vicinity of heat sources and do not expose to sun light

• Before op er ating the unit after tra ns por t , wait ab ou t one hour after setting it up. This will allow any oil that has accumulated laterall y dur i n g tr ansport to flow back dow n thus e ns ur ing maximum cooling performance of the compressor.

5.2. Bath fluids

Carefully read the safety data sheet of the bath fluid used, particularly with regard to the fire poi nt! If a bath fluid with a fire point of ≤65 °C is used, on l y supervised operation is possible.

Water: The quality of water depends on local conditions.

• Due to the high concentration of lime, hard water is not suitable for temperature control because it leads to calcification in the bath.

• Ferrous water can cause corrosion - even on stainless steel.

• Chloric water can cause pitting corrosion.

• Distilled and deionized water is unsuitable. Their special properties cause

Temperature application to external, open systems

The circulator is equipped with both a pressure and suction pump for external temperature application in open systems.

Differing flow rates of the pressure and suction pumps should be compensated. To maintain a constant liquid level, the JULABO „D+S“ Level Adapter is recommended for the external bath tank. The flow rate of the pressure pump will be then regulated by a built-in float device. The liquid level may be changed by a height adjustment on the „D+S “ Lev el Ada pter.

At high working temperatures the tubing use d for tem perature applicati on and cooling water supply represents a danger source.

This may result in:

• Burning o f ski n

• Difficul t ies i n br ea thi n g due to hot atmos p here

Safety recommendations

• Employ suitable connecti ng tu bi n g.

• Make sure that the tubing is securely attached.

• Avoid sharp bends in the tubing, and maintain a sufficient distance from

surrounding walls.

• Regularly check the tubing for material defects (e.g. for cracks).

•

Check the temperature of the bath fluid prior to draining (by switching the unit on

protection.

5.4. Filling / draining

Notice:

• Pay attention to the thermal expa ns i o n o f ba th oi l duri ng heating to avoid overflowing of the liquid.

• Do not drain the bath fluid while it is hot! Recommendation: Temperature range 5 °C to 40 °C

for a short moment, for example).

• Store and dispose the used bath fluid according to the laws for env i ronmental

Filling

Take care that no liquid enters the interior of the circulator.

• Recommended maximum filling level with water as bath fluid: 30 mm bel ow t he ta nk rim

• Recommended maximum filling level with bath oils: 40 mm below the tank rim

 After filling, immerse the samples in the bath or place the lid on

the bath, in case the opening is not to be used.

 The circulator provides an early warning system for low level that

may be triggered when changing samples in the bath.

Draining

• Turn off th e cir culator and cooling ma c hi n e.

• Hold the venting grid, pull out and remove.

• Slide a short piece of tu be on to t h e dr ai n por t a nd hol d it in to a

pail.

• Unscrew the drain tap (19) and em pty the unit completely.

• Tighten the drain tap.
