One of the most common problems in a water/glycol system is the presence of air in the
condenser water loop. Air vents must be installed in various locations the piping system
to purge the air.
Water/glycol system piping may include a centrifugal pump (or pumps for redundancy). Pumps
must be primed before operating per the pump manufacturer’s guidelines.
