(1) The unit is mL.Note: Always use new refrigerant oil and clean equipment to avoid contamination inside the air conditioning system.Note: Make sure that the equipment for oil injection does not contain air in the supply line to the air conditioning system. This prevents air from being injected into the system which can lead to poor cooling performance and possible system damage.Note: Oil should only be charged into the discharge service port. Failure to charge the oil correctly can damage to the compressor from liquid slugging with oil.
