2- Add or remove charge in increments. Allow the
system to stabilize each time refrigerant is added or
removed.
3- Continue the process until measured liquid
temperature agrees with the target liquid
temperature. Do not go below the target liquid
temperature when adjusting charge. Note that
suction pressure can change as charge is adjusted.
4- Example: At 95°F outdoor ambient and a measured
suction pressure of 130psig, the target liquid
temperature is 98°F. For a measured liquid
temperature of 106°F, add charge in increments until
measured liquid temperature agrees with the target
liquid temperature.
