2. Pressure test the entire system (all zones).

3. Connect manifold gauges, micron gauge, and vacuum pump and evacuate

the linesets.

4. Pull a vacuum down to 500 microns.

5. Close manifold gauge valves and open both the service valves fully, re-

leasing refridgerant into the system.

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.

and check all zones for functionality.

8. Ensure the gauges do not show any rescrition.
