1 Safety information
1.1 General safety information
A laboratory thermostat is used to heat, cool and circulate liquids as specified. Hazards arise from this
due to high or low temperatures, fire and the general hazards due to the application of electrical en-
ergy.
The user is largely protected by the application of the relevant standards.
Further hazard sources can arise from the type of material for which the temperature is to be stabilized,
e.g. with the exceeding or undercutting certain temperature thresholds or with the fracture of the con-
tainer and reaction with the heat transfer liquid. It is not feasible to include all possible situations. They
remain essentially subject to the judgement and responsibility of the operator.
The devices may only be used as intended, that is as described in this operating manual. This includes
operation by instructed specialist personnel.
The devices are not designed for use under medical conditions according to DIN EN 60601-1 or IEC
601-1.

8Safety information 28.04.10/ YACE0088
1.2 Other safety information
•Check the device carefully for shipping damage before putting into operation. The device should not
be put into operation if shipping damage has been found.
•Only connect devices to earthed mains sockets.
•At higher operating temperatures parts of the bath cover can take on surface temperatures of over
70 °C. Be careful when touching the device.
•Use suitable hoses (Ì6.4).
•Secure hoses against slippage by using hose clips. Avoid kinking the hoses.
•Check the hoses from time to time for any material fatigue.
•Hoses with hot heat transfer liquid and other hot parts must not come into contact with the mains
cable.
•When using the thermostat as a circulation thermostat, hot liquid can escape due to hose fracture
and become a danger to personnel and materials.
•If no external load is connected, the feed nozzle must be sealed off (use the sealing plug) or short-
circuit it to the return nozzle.
•Pay attention to the thermal expansion of the heat transfer liquid with increasing bath temperature.
•Toxic vapours may be generated depending on the heat transfer liquid used and the operating mode.
Ensure adequate air extraction.
•Attach immersion thermostats carefully to the bath vessel.
•Only use bath vessels which are suitable for the intended operating temperatures.
•Always set the overtemperature cut-off point immediately according to the heat transfer liquid used
when filling.
•When changing the heat transfer liquid from water to other liquids for temperatures above 100 °C,
carefully remove all residues of water including from the hoses and loads, otherwise there is a risk of
scalding due to delay in boiling.
•Use cooling coils with cooling water only for operating temperatures below 100 °C, because with
higher temperatures there is the risk of superheated steam forming.
•Withdraw the mains plug before cleaning, servicing, installing or removing modules or moving the
thermostat.
•Have repairs to the control section carried out only by specialists.
•Keep to service and maintenance intervals according to VDI 3033 (Ì9.4.1).
•The figures in the technical data apply under standard conditions according to DIN 12876. Electro-
magnetic high frequency fields can in special cases lead to unfavourable values. Safety is not impai-
red.

4.1 Ambient conditions
Use of the thermostating unit is only admissible under the conditions stated in
DIN EN 61010-1:2001 and DIN EN 61010-2-010:2003 :
−Operation only indoors.
−Elevation up to 2000 m above seal level.
−Siting base impermeable, flat, non-slip and non-flammable.
−Keep distance to walls (Ì6.1).
−Ambient temperature (Ì11).
The ambient temperature must be taken into account.
−Permissible mains voltage variations (Ì11).
−Maximum relative humidity 80 % up to 31 °C and decreasing linearly to 50 % up to 40 °C.
−Overvoltage Category II and transient overvoltages according to Category II.
−Contamination Level: 2.
4.2 Device types
Heating thermostats
The type designation of the heating thermostats is composed of the prefix E for ECO, the approximate
bath volume in litres and a G for the GOLD device variant.
Example: E 10 G is a heating thermostat with a maximum bath volume of 10 litres in the GOLD device
variant.
With the heating thermostats with a transparent bath there is the prefix of ET for the ECO transparent
bath, followed by the bath volume in litres and a G for the device variant GOLD.
Example: ET 6 G is a heating thermostat with a transparent bath with a maximum bath volume of 6 litres
in the GOLD device variant.
Cooling thermostats
The type designation of cooling thermostats is composed of the prefix R (to identify the cooling device:
Refrigerated), an E for ECO, the bath volume in litres, the minimum attainable temperature (without ar-
ithmetical sign) and a G for the device variant GOLD.
Example: RE 415 G is a heating thermostat with a maximum bath volume of 4 litres and a minimum tem-
perature of -15 °C.
4.3 Pump
All devices are equipped with a pressure pump. The pump has an output with a pivotable outflow elbow.
With the bath and circulation thermostats this is joined to the pump set for external tempering circuits. An
additional output is used for internal bath circulation. By switching the selector at the front on the control
head, the flow can be manually selected or divided between the two outputs.
In the heating range the pump operates up to viscosities of 150 mm²/s. In the controlled mode 30 mm²/s
should not be exceeded.
Using the operating menu, one of six flow-rate levels can be selected for the pump. For small bath ther-
mostats a power level of 1 to 3 is practicable.
When operated as a circulation thermostat with an external load, a higher power level is practicable to
keep the temperature difference between the bath and external load small even at higher temperatures.
The pump connection of the outflow can be closed without any detrimental effects on the pump.

4.8 Chiller
The chiller mainly consists of a fully hermetically sealed compressor. The dissipation of the condensation
and motor heat takes place via a fan-ventilated lamellar condenser. Here, atmospheric air is drawn in at
the front of the device, heated up and discharged at the back and sides. To ensure proper air circulation
the ventilation openings must not be covered up.
The compressor is equipped with a thermal release which responds to the compressor temperature and
current consumption. The chiller is normally switched in automatically, but can also be switched in
manually via the operating menu (Ì7.5.5).
The chiller is switched off when a malfunction occurs which affects safety.
The Cooling Thermostat RE 1050 G is equipped with the SmartCool technology which makes optimum
use of the compressor and only chills when cooling output is demanded by the controller. To achieve
this, several sensors in the cooling circuit monitor the operating status.
Cooling times for the various cooling thermostats can be taken from the cooling curves (Ì11).
