• Once all of the copper lines are connected, vacuumed down to 500

microns, and the refrigerant is released, start the system.

• Ensure the gauges do not show any restriction

• Remove gauges once the system is operating properly.

NOTE

It is harmful to remove the gauges while the lineset is under vacu-

um. Keep the gauges connected until the vacuum is complete and

the refrigerant has been released into the lineset.

Multizone:

• Connect each zone’s copper lines one at a time. After connecting the first

set of copper lines, and the pressure test is complete, connect your mani-

fold gauges, micron gauge, and vacuum pump and evacuate the lineset.

• Once it is confirmed that the joints have a proper connection, pull a vacu-

um down to 500 microns.

• After the vacuum is complete, close manifold gauge valve(s), and open

both the service valves fully, release the refrigerant into the system, and

start the system.

• Move onto the next zone’s copper lines, connect them, and repeat steps

1-4.
