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

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

periodoftime.

- Checkthefunctionofthetwofansbyvisualinspection.

Other operation controls

On the front side of the temperature control unit there are

covered shock-proof sockets for the connection of BOD's

appliances or stirring apparates. The total load on the sockets

must not exceed 4,5 amps.

•Donotdamageorremovethetypeplateonthein-

sideoftheappliance.Itisveryimportantforservicing

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.
