– COOLER DRAIN DETAIL
AFTERCOOLER PIPING - At shutdown of the system, all units should be drained completely of
condensate if there is any possibility of freezing or corrosion damage. To help remove the condensate,
the cooler may be tapped per (
Figure 5-5), and a drain cock installed. After opening the drain cock, blow
air into the cooler from a connection on the opposite side of the cooler. At the same time the connection
on the drain side of the cooler should be plugged. The drain cock should be left open until the machines
are ready for start-up.
Failure to remove condensate from an idle cooler in freezing temperatures will
cause permanent cooler damage. Drain condensate after system shutdown. It
is the owner/operator's responsibility to ensure that condensate has been
drained and cooler dried out to prevent cooler damage.
