5. Unit Description
All unitsfulfillthe requirementsof safetyclass 2 accordingto
DIN
12879 and are thus suitablefor unsupervisedcontinu-
ous operation.
Thecirculator pumpmotorisprotectedagainstthermalover-
loading.
All temperaturesensorsarepermanentlymonitored
according
to break or short circuit. The cooling machine is
integratedintothe generalsafety circuit.
The control of the preselected temperature
is carried out
automaticallyvia the Thermo Haake ~uzz~~tar@control.
5.1 Safety features
The comprehensivesafetysystemisdesignedonthe princi-
ple of the concept of the "singlefault"
(EN 61 010). This as-
sumesthattwo separatefaultsdo notoccursimultaneously.
This systemtherefore offers protectionagainst
one (single)
fault. This one fault will effectively occur automatically
...
if you do not readthis manual,
if you do not correctly set the excess temperature
protection,i.e.the safety reserves have already been
used up.
Such faults can include e.g.:
Fault in the temperature control unit:
=. Excesstemperature poss.fire danger
Leakagein the liquid circuit or
Evaporationof heat transfer liquid:
=. Low liquid level - poss.fire danger
Pump blocked or
Heattransfer liquid is too highly viscous:
* Motor overheating - poss.fire danger
Or also:
Excesstemperature protection level not correctly set:
=+ poss.fire danger

Unit Description
5.2 Safety class 2 accordingto DIN 12879
A variably adjustableexcesstemperature protection and in-
dependent low liquid level protection which is preset to the
lowestlevelallowthe usageof differentheattransfer liquids.
If a safety element istriggered..
.
the cause for the fault is displayed,
the safety-relevant components (heating element,
motor and compressor) are switched off immediately
i.e.the safety circuittransfers the unit to a stable, safe
condition,
the temperature of the heat transfer liquid gradually
adjusts to ambient temperature.
5.3 Applications
As open-bath circulator:
Fortemperaturecontrolling sampleswithin the circula-
tor's own bath.
As heating circulator:
Fortemperaturecontrollingclosedtemperature control
circuits such reactors, heat exchangers or similar ob-
jects.
Temperature controlling of open vessels using the
built-in combined pressure and suction pump.
5.4 Temperature ranges
Working temperature range:
The temperature range of the circulator without addi-
tional heating or cooling sources.
Operating temperature range:
The temperature range of the circulator which can be
reached if additional heating or cooling sources are
used.
Tap water canbeusedasacoolingsource. Inthiscase
the minimum working temperature possible is approx.
3°C above that of the tap water temperature.
!
High operating temperatures mean the unit sur-
faces heat up.Protectivemeasuresmust
be taken!

6.4 Restingtime after transportation
(only for refrigeratedcirculators)
As we canunfortunately not guaranteethat our refrigerated
circulatorsare alwaystransported accordingto our recom-
mendations (i.e. upright), lubrication oil can leak from the
compressor intothe cooling circuit.
If the refrigerated circulator is started up whilst still in this
state,the compressor may be damagedtothe lack of oil.
Therefore:
!
Restthe unitfor 24 hoursafter setting up.
6.5 Ventilation
Keep allventilation grids (onfront and rear) free from
obstructionto ensure unhinderedair circulation.
(
Blocked ventilation grids lead to increased unit
=
heatingwhich inturnreducesthecoolingcapacity
andthus impairs correctfunctioning.
