Ukuncitshiswa rhoqo kweekhabhathi zasesiqithini zevenkile enkulu kubalulekile.Kwikhabhinethi yesiqithi sokupholisa ngokuthe ngqo, isixa esikhulu seqabaka siya kwenziwa eludongeni lwangaphakathi emva kwexesha elide lokusetyenziswa.Ukuba ayisuswanga, iya kuchaphazela isiphumo sokusetyenziswa kwekhabhinethi yesiqithi esikhulu esibandayo, kwaye umphumo wokupholisa uya kuncitshiswa kakhulu.Ngokuqhelekileyo, i-frost layer ifuna ukuchithwa xa i-frost layer ifikelela kwi-5 cm.Ukugcina le ngxaki, ungasebenzisa i-air-cooled island cabinet.
