Air Evacuation; Evacuation Instructions - CANVAC T-Series Installation Manual

AIR EVACUATION

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 the unit is relocated.
BEFORE PERFORMING EVACUATION
• Check to make sure that both high-pressure and
low-pressure pipes between the indoor and
outdoor units are connected properly in accord-
ance with the Refrigerant Piping Connection
section of this manual.
• Check to make sure all wiring is connected
properly.

EVACUATION INSTRUCTIONS

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