CAUTION: Overcharging a system with a stuck open Thermostatic Expansion Valve (TXV) may allow liquid refrigerant to enter the compressor,
causing compressor noise and damage. Overcharging will flood the evaporator with liquid refrigerant causing insufficient cooling due to reduced heat
transfer. Undercharging will also cause insufficient cooling.
