- Page 11 See the following table for tightening torque. Cautions for installation of multiple outdoor units (Applying too much torque may cause the flares to crack.) The piping between the outdoor units must be routed level or slightly upward to avoid the risk of oil detention into the piping side. After all the piping has been connected, use nitrogen to perform a gas leak check.
