Removal
(1) Connect the manifold gauge to the high- and low-pressure outlet ports at the outdoor unit where the compressor
will be replaced. Connect the manifold gauge to a nitrogen cylinder and perform nitrogen gas replacement.
(2) Remove the panels and the corresponding parts from the outdoor unit where the compressor will be replaced.
(3) Remove the cap and acoustic material that surrounds the compressor.
(4) Remove the cap at the compressor terminal plate. Disconnect the power cable.
(5) Remove the crankcase heater.
(6) Disconnect the tube-with-flare-nut using wrenches. At this time, cover the tube in place with waste cloth while
watching out for oil leaks. Then cap the disconnected tube and mount the flare nut on the compressor. Tighten
the flare nut with a seal bonnet(1/4") in it.
Attach the caps to prevent
oil from flowing out after
removing the flare nuts.
