Placing System In Operation

After component replacement and/or system servicing has been completed and all connections have been made, proceed as follows:

  1. Evacuate the system using vacuum pump.
  2. Charge the system with R-12. See REFRIGERANT CAPACITIES in A/C SYSTEM SERVICE SPECIFICATIONS - CAR or TRUCK in this article.
  3. Leak-test the system, with particular attention to all new connections and components.
  4. Make a performance test of the system. Never assume that a Recharging has automatically corrected a problem.
