3. Unitoperation
Initialinspection
Priortoshipmentthisunitwasinspectedandfoundfreeofmechanicalorelectricaldefects.Upon
unpackingoftheunit,inspectforanydamage,whichmayhaveoccurredintransport.Theinspection
shouldconfirmthatthereisnoexteriordamagetotheunit,suchasbrokenknobsorconnectors,and
thatthepanelsarenotscratchedorcracked.Keepallpackingmaterialuntiltheinspectionhasbeen
completed.Ifdamageisdetected,fileaclaimwithcarrierimmediatelyandnotifyCAEN.Before
installingtheunit,makesureyouhavereadthoroughlythesafetyrulesandinstallationrequirements,
