R-410ATechnical
Guidelines
Applications: Air conditioning equipment and heat pumps. Only for newly manufactured equipment, not for retrofitting R-22 systems
Performance: Presures are 60% higher than R-22, therefore should be used only in new equipment
Lubricant Recommendation: Compatible with polyolester lubricant
Retrofitting: For new equipment only
