AQUAZONE CONTENTSSAFETY CONSIDERATIONS Installation, Start-Up,and Service InstructionsGENERAL INSTALLATIONSTORAGE - If the equipment is not needed immediately at the jobsite, it should be left in its shipping carton and stored in a clean, dry area of the building or in a warehouse. Units must be stored in an upright position at all times. If carton stacking is necessary, stack units a maximum of 3 high.
