LONE STAR

It is critical to the performance and durability of Subaru Air Conditioners that the above charge limits be adhered to.
2. USE OF SIGHT GLASS
The sight glass in all Subaru Air Conditioners cannot be used to accurately gauge the amount of R-12 in the system. Bubbles may appear in the sight glass even though the system contains the correct amount of R-12. This is especially apparent when the condenser fan cycles since the refrigerant in the condenser begins to boil when the fan cycles off.
