∗
This model is slightly different from other models, but there is no significant difference
regarding the measuring points.
1.28 Inspecting the Check Valve
1. While the unit is running, check if a temperature difference exists between points A and B in
the pipe when the pipe internal pressure is lower at point A than at point B. If there is no
temperature difference, chances are that refrigerant is leaking.
2. When a slight amount of refrigerant is leaking, frost may be observed upstream and
downstream of the check valve.
