These documents must be removed priorto commissioning.Several subassemblies and components must be commissioned separately. Therelevant steps are listed in the following chapter.ELECTRICAL HAZARD!The following applies for all maintenance and cleaning work: the doors of theunit may only be opened if the unit has been switched off and cannot beaccidentally switched back on.DANGER DUE TO EXPLOSION RISK AREA!Particular attention must be paid to safety information and (electrical)installation information for units operating in explosion risk areas. Noncompliancewith these regulations may lead to explosions that could causesevere injury to persons and major damage to property!DANGER FROM ROTATING UNIT PARTS!The fans do not come to a standstill immediately when the unit has beenpowered down. You should therefore wait for at least 5 minutes until the fanshave come to a standstill before starting maintenance and repair work.DAMAGE TO THE UNIT!When mounting GEA CAIR units care must be taken to ensure that no loadsare applied to the floor panels. During installation and maintenance work,suitable measures should be taken to ensure that any load is spread across thebottom profiles (e.g. using grid walkways).Maintenance intervalsThe maintenance intervals specified apply for air with normal levels of contamination.The maintenance intervals must be reduced accordingly for air with particularlyhigh levels of contamination.NOTECleaning should be carried out more regularly if the air contains oil as thesealing materials are only resistant to oil for a limited period.Only use alcohol-based disinfectants.PERSONAL PROTECTIONA mask and protective gloves must be worn when carrying out cleaning andspecific maintenance tasks at the unit.PR-2009-0096-GB • Subject to modifications • Status 07/2010 51
