line port. However, connecting it to the vapor port better protects the manifold gauge set from high pressure damage.

BWith both manifold valves closed, connect the cylinder of HFC−410A

refrigerant to the center port of the manifold gauge set.

TEST FOR LEAKS

After the line set has been connected to the indoor and outdoor units, check the line set connections and indoor unit for leaks. Use the following procedure to test for leaks:

1.With both manifold valves closed, connect the cylinder of HFC−410A refrigerant to the center port of the manifold gauge set. Open the valve on the HFC−410A cylinder (vapor only).

2.Open the high pressure side of the manifold to allow HFC−410A into the line set and indoor unit. Weigh in a trace amount of HFC−410A. [A trace amount is a maximum of two ounces (57 g) refrigerant or three pounds (31 kPa) pressure]. Close the valve on the HFC−410A cylinder and the valve on the high pressure

side of the manifold gauge set. Disconnect the HFC−410A cylinder.

3.Connect a cylinder of dry nitrogen with a pressure regulating valve to the center port of the manifold gauge set.

4.Adjust dry nitrogen pressure to 150 psig (1034 kPa). Open the valve on the high side of the manifold gauge set in order to pressurize the line set and the indoor unit.

5.After a few minutes, open one of the service valve ports and verify that the refrigerant added to the system earlier is measurable with a leak detector.

6.After leak testing disconnect gauges from service ports.
