Conducting the soap visual gas leak test
1. To monitor the system pressure over time, install a high-quality, high-resolution analog
pressure gauge on one of the shells. Use a pressure gauge that has a resolution of 2 psi
increments with a dial face at 3 in. in diameter or greater.
2. Before proceeding, make sure that the unit is at the initial evacuation level of 5 mmHg.
Important:
To prevent freezing of any moisture that might be in the system, do not go
below 5 mmHg. See
for more details.
3. With the system evacuated, charge the system with dry nitrogen to 100 psig (690 kPa).
