R A R A is a high-pressure refrigerant (+ 0% in relation to R 22 and R 0 C). The compressors approved for operation with this fluid are filled beforehand with polyalcohol oil. Contrary to mineral oil, it is very hygroscopic: it absorbs the humidity of the ambient air very quickly. This can modify its lubricant properties and lead in time to the destruction of the compressor. MAINTENANCE INSTRUCTIONS - Never add oil to the appliance; the compressor is filled with polyalcohol oil, a special oil which cannot tolerate the presence of other oils. 2 - The instruments used for: - filling, - pressure measurements, - emptying under vacuum, - recovering the fluid, must be compatible and only used for the R A fluid. Note: the pressure taps of the refrigerating circuit are / SAE (/2-20 - UNF) APPLIANCES FILLED WITH R A - In the case of a new charge: - the charge must be undertaken in liquid phase, - use a balance and a dip pipe type R A cylinder, - charge the weight of R A as per the value indicated on the unit s identification plate (for split systems, refer to the installation instructions as the charge must consider the length of the connecting lines). - In case of leakage, do not complete the charge: recover the remaining refrigerant for recycling and perform a total charge. Recovery, recycling or the destruction of the fluid must be done in compliance with the laws in force in the country concerned. - If the refrigerant circuit is opened, you must: - avoid the entry of air into the circuit as much as possible, - replace or install a drier, - perform the vacuum operation at a minimum level of 0. mbar (static). - APPLICATION - USE Chilled water or hot water generator for air conditioning or heating of rooms for terminal unit and boiler overhaul applications. NOTE : The electronic control parameterization is factory-set for terminal unit and boiler overhaul applications. 2
