Compatible Lubricants & Charging
Compatible Oils
Mineral Oil (MO) or Alkylbenzene (AB)
Charging Procedures
- •Can be charged in either liquid or vapor phase since it is a single-component pure gas.
- •Charge slowly into the suction side if charging as vapor, checking gas pressures and current draw.
Leak Checking & Eco Recovery
Leak Detection Methods
- •Soap bubble solution test
- •Electronic halogen leak detectors
- •UV fluorescent dye checks
Recovery & Recycling
- •Must recover using dedicated R-22 recovery cylinders. Venting is illegal in India (under Ozone Rules).
Retrofitting & Gas Substitution Advice
Retrofitted with R-407C or R-427A, requiring mineral oil flushing and POE lubricant swap.
