Correct answer
Only after the leak is repaired
Why
Adding refrigerant to a leaking system without repair is considered venting. Leaks must be repaired before or simultaneously with refrigerant addition.
The concept behind this question
Section 608 splits technician certification by the equipment you work on: Type I for small appliances, Type II for high-pressure systems, Type III for low-pressure systems, and Universal for all three. Core is mandatory for every certification and covers the material common to all of them. Certification does not expire. The regulations also govern leak repair thresholds, recordkeeping, and the disposal and final-venting requirements that apply when equipment reaches end of life.
