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.
Classes in the EMC standard DIN EN 61326-1.
Class A: Operation only on electrical supply networks without connected domestic areas.
Class B: Equipment for operation on electrical supply networks with connected domestic areas.
With unfavourable network conditions interfering voltage variations can occur.
Class of protection for electrical oper-
ating equipment
DIN EN 61140 (VDE 0140-1) Class I
EMC requirements to DIN EN 61326-
1 (corresponds to VDE 0843-20-1)
applies to Europe Class B
for Canada and the USA Class A
EC directives The devices conform to the directives of the European Parlia-
ment and of the Council: 2004/108/EC regarding electromag-
netic compatibility (EMC) and 2006/95/EC relating to electrical
operating equipment for use within certain voltage limits (Low
Voltage Directive).
The devices bear the CE label.
Usage restriction
For the EMC standard DIN EN 61326-1:
Devices in Class A are only to be operated on electrical supply networks without connected
domestic areas.

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.
