1. Install the connecting tubes of the
indoor/outdoor unit.
2. DO NOT OPEN THE GAS VALVES UNTIL THE
EVACUATION PROCESS IS COMPLETE.
3. Remove the gas line service port cap and
connect the gas valves of the vacuum gauge,

4. Start the vacuum pump. (Running time should
be more than 15 minutes.)
5. Check the vacuum with the vacuum gauge. The
gauge should read -30 in. Hg. After evacuation,
fully close the handle on the manifold valve
(on the vacuum pump device). Then stop the
vacuum pump and disconnect it.
