Safety instructions and warnings
Topreventinjuryordamagetotheunit,theapplianceshouldbe
unpackedandsetupbytwopeople.
Intheeventthattheapplianceisdamagedondelivery,contact
thesupplierimmediatelybeforeconnectingtothemains.
Toguaranteesafeoperation,ensurethattheapplianceissetup
andconnectedasdescribedintheseoperatinginstructions.
Disconnecttheappliancefromthemainsifanyfaultoccurs.Pull
outtheplug,switchofforremovethefuse.
Whendisconnectingtheappliance,pullontheplug,notonthe
cable.
Anyrepairsandworkontheapplianceshouldonlybecarriedout
bythecustomerservicedepartment,asunauthorisedworkcould
provehighlydangerousfortheuser.Thesameappliestochanging
themainspowercable.
Donotallownakedflamesorignitionsourcestoentertheappli-
ance.Whentransportingandcleaningtheappliance,ensurethat
therefrigerantcircuitisnotdamaged.Intheeventofdamage,
make sure that there are no ignition sources nearby and keep the
roomwellventilated.
Donotstandontheplinth,drawersordoorsorusethemtosup-
portanythingelse.
Thisappliancecanbeusedbychildrenof8yearsoldandover,and
alsobypersonswithrestrictedphysical,sensoryormentalcapacity
orlackofexperienceandknowledge,iftheyaresupervisedor
have been instructed on safe use of the appliance and understand
theresultingrisks.Childrenmustnotbeallowedtoplaywiththe
appliance.Cleaningandusermaintenancemustnotbecarried
outbychildrenwithoutsupervision.
Avoidprolongedskincontactwithcoldsurfacesorchilled/frozen
food.Thiscouldcausepain,numbnessandfrostbite.Inthecase
ofprolongedskincontact,protectivemeasuresshouldbetaken,
e.g.glovesshouldbeworn.
Donotstoreexplosivesorspraysusingcombustiblepropellants
suchasbutane,propane,pentane,etc.intheappliance.Electrical
componentsmightcauseleakinggastoignite.Youmayidentify
suchspraysbytheprintedcontentsoraflamesymbol.
Ifyouhavealockableappliance,donotkeepthekeynearthe
applianceorwithinreachofchildren.
Theapplianceisdesignedforuseinenclosedareas.Donotoperate
theapplianceoutdoorsorinareaswhereitisexposedtosplash
waterordampconditions.
Donotplaceitemswithtoohightemperatureintheinterior.
Disposal notes
The appliance contains reusable materials and should be
disposedofproperly-notsimplywithunsortedhousehold
refuse.Applianceswhicharenolongerneededmustbe
disposedofinaprofessionalandappropriateway,in
accordancewiththecurrentlocalregulationsandlaws.
Whendisposingoftheappliance,ensurethattherefrigerantcircuit
is not damaged to prevent uncontrolled escape of the refrigerant
itcontains(dataontypeplate)andoil.
Do not vent R134a into atmosphere.
R134a is a fluorinated greenhouse gas, covered by
Kyoto Protocol, with a Global Warming Potential
(GWP) = 1300.

Trouble shooting
Ifthevericationofthetemperatureaccuracyisnotsuccessfulthe
followingshouldbetakenunderconsideration:
- The ambient temperature of the thermostatically controlled
incubatormustmatchtheclimaterate(typeplate).
- Acertaincirculationofairisnecessaryforthecompressorto
workproperly.
- Theincubatorshouldnotbeopenedtooftenand/orforlonger
periodoftime.
- Checkthefunctionofthetwofansbyvisualinspection.
- Checkthecoolingdevicebysetting10°Candwaitforasigni-
cantchangeofthetemperatureinthesampletowards10°C.
- Checktheheatingdevicebysetting40°Candwaitforasigni-

purposes.
•Important! The compressor and other parts may
stillbehotfromoperation.
Do not use steam cleaners because of the risk
of injury and damage.
Defrosting
Whenoperatingataverycoldthermostatsetting,theinteriorrear
wallmayiceup.
Inthiscase,theappliancemustbedefrostedmanually.
•Pull out the mains plug!
•Leavethedooroftheapplianceopenwhiledefrosting.
Defrostedwatercollectsinanevaporatortrayandis

drainageopeninginthebackpaneloftheincubator.
The drainage opening should, when necessary be
cleanedwiththeaidofasuitabledevice(e.g.bottle

andcleantheappliance.
Do not use any mechanical devices or other
artificial aids for defrosting other than those
recommended by the manufactur er.

itoffanddisconnecttheplugorswitchofforunscrewthefuse.
Cleantheapplianceandleavethedooropeninordertoprevent
unpleasantsmells.
The permissible room temperature for storing the appliance
after decommissioning is between -10°C and +50°C.
Storing the appliance outside this temperature range can
damage the appliance and cause it to malfunction.
