LINE SET INSTALLATION
1. Remove the valve cores from the service ports on the liquid and gas line stubs using no-loss valve core re-
moval 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 gauge set to one of the ports on the 1/4” SAE in-line tee.
4. Connect a micron gauge to the remaining port of the 1/4” SAE in-line tee.
5 . Connect the high pressure side of the manifold gauge set to the liquid line stub service port.
6. Connect a vacuum pump to the center port on the manifold gauge set.
7. Open the valve core removal tool valves.
8. Open the high and low pressure sides of the manifold gauge set and start the vacuum pump.
9. After evacuating for a few minutes, close the high and low pressure sides of the manifold gauge set and observe
the behavior of the micron gauge. A rapid rise in the micron gauge reading (pressure) indicates a leak in the sys-
tem. If this occurs, check the manifold gauge 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 gauge set and stop the vacuum pump.
12. Wait 10 minutes.
13. If the micron gauge reading
rises above 800 microns, check
for leaks and return to step 9.
14. If the micron gauge 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 gauge 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
gauge set and proceed to the
next section to charge the sys-
tem.
