9 Evacuation All new installations must be evacuated to a deep vacuum in order that all noncondensible gases and moisture are removed prior to charging the system. Air in a system causes high condensing pressure, which increases power consumption and reduces performance.
1.Fully open both shutoff valves. 2.Connect service gage manifold to the valve service ports, being sure to evacuate lines. 3.Startup the system (Refer to the Section 7 - "System Startup"). Run system at least 10 minutes to allo pressure to stabilize.
