Air evacuation

8.1 Preparations and precautions

Air and foreign matter in the refrigerant circuit can cause abnormal rises in pressure, which can
damage the air conditioner, reduce its efficiency, and cause injury. Use a vacuum pump and manifold
gauge to evacuate the refrigerant circuit, removing any non-condensable gas and moisture from the
system.
Evacuation should be performed upon initial installation and when unit is relocated.
Before performing evacuation
• Check to make sure that both highpressure and low-pressure pipes between the indoor and outdoor
units are connected properly in accordance with the Refrigerant Piping Connection section of this
manual.
• Check to make sure all wiring is connected properly.

8.2 Evacuation instructions

Before using the manifold gauge and vacuum pump, read their operation manuals to familiarize
yourself with how to use them properly.
