r.lauziere Posted July 7, 2019 Share Posted July 7, 2019 !995 Mack CL 713 a/c not working. Want to add some Freon to compressor to see if it's low. Does it get added to the DIS. side or SUC. side of the compressor. No other areas to connect a hose to.

0 Mack Technician Posted July 7, 2019 Share Posted July 7, 2019 (edited) Add it to the suction side while running. The goal is to not jet liquid into the suction which could cause compressor damage via incompressible liquid. That means adding slowly or out of the gas column of the can.
