English SPL040-060 3 / 46 Maintenancea) The machine is designed and built to guarantee continuous opera-tion; however, the life of its components depends on the mainte-nance performed;b) when requesting assistance or spare parts, identify the machine(model and serial number) by reading the data plate located on theunit.6.1 General instructions! Before any maintenance, make sure:• the pneumatic circuit is no longer pressurized;• the dryer is disconnected from the main power supply. Y Always use the Manufacturer’s original spare parts: otherwise theManufacturer is relieved of all liability regarding machine malfunction-ingY In case of refrigerant leakage, contact qualified and authorized per-sonnel.Y The Schrader valve must only be used in case of machine malfunc-tion: otherwise any damage caused by incorrect refrigerant charging willnot be covered by the warranty.6.2 Refrigerant.Charging: any damage caused by incorrect refrigerant replacement car-ried out by unauthorized personnel will not be covered by the warranty.ZY The equipment contains fluorinated greenhouse gases.At normal temperature and pressure, the R134a refrigerant is a colour-less gas classified in SAFETY GROUP A1 - EN378 (group 2 fluid ac-cording to Directive PED 2014/68/EU)GWP (Global Warming Potential) = 1430.! In case of refrigerant leakage, ventilate the room.6.3 Preventive Maintenance ProgrammeTo guarantee lasting maximum dryer efficiency and reliabilityMaintenanceActivity DescriptionMaintenance Interval(standard operating conditions)ActivityCheck ServiceDailyWeekly4 Months12 MonthsCheck POWER ON indicator is lit.Check control panel indicators.Check condensate drain.Clean condenser fi ns.Check electrical absorption.Depressurize the dryer.
