1. Remove the valve cores from the service ports on the liquid and gas line stubs using no-loss valve core removal tools.
2. Connect a 1/4” SAE in-line tee to the gas line stub valve core removal tool.
3. Connect the low pressure side of the manifold gage set to one of the ports on the 1/4” SAE in-line tee.
4. Connect a micron gage to the remaining port of the 1/4” SAE in-line tee.
5. Connect the high pressure side of the manifold gage set to the liquid line stub service port.
6. Connect a vacuum pump to the center port on the manifold gage set.
7. Open the valve core removal tool valves.
8. Open the high and low pressure sides of the manifold gage set and start the vacuum pump.
9. After evacuating for a few minutes, close the high and low pressure sides of the manifold gage set and observe the behavior of the
micron gage. A rapid rise in the micron gage reading (pressure) indicates a leak in the system. If this occurs, check the manifold
gage set, hoses, tee, and valve core removal tools for leaks. If no leak is found, repeat the leak test procedure on Page 15.
10. Evacuate the line set and dehumidifier for a minimum of 15 minutes and check that the micron gauge reads below 500
microns.
11. Close the low and high pressure sides of the manifold gage set and stop the vacuum pump.
12. Wait 10 minutes.
13. If the micron gage reading rises above 800 microns, check for leaks and return to step 9.
14. If the micron gage reading remains
below 800, close the valves on the
valve core
removal tools.
15. Remove the tee from the gas line
stub valve core removal tool. Connect
the low pressure side of the manifold
gage set to the gas line stub valve core
removal tool.
16. Install the valve core into the liquid line
stub service port.
17. Remove the vacuum pump from the
center port of the manifold gage set and
proceed to the next section to charge
the system.
