REMOTE MOUNTED ELEVATED COOLER ASSEMBLY PROCEDURE
- The Compressor package will
be built and tested with the coolers mounted on the package. On enclosed units, the fan motor will be
disconnected after test and the vent fan motor connected in its place. The vent fan will be mounted in the
enclosure. A contactor (starter) will be shipped loose and remote mounted with the cooler by others upon
start-up at the job site. The control box will be wired for remote elevated coolers at the factory.
NOTICE
All requirements of local codes should be followed.
When connecting pipe fittings to the cooler, support the threaded coupling with a pipe wrench when
tightening the connection. Use silicone sealant on all steel to aluminum threaded connections. All piping
should be firmly supported to avoid strain on the cooler manifold and connections. Flexible connections
should be installed in all interconnecting piping, adjacent to the cooler, to avoid transmitting piping weight
or vibrations to the cooler elements. Before beginning installations, check to be sure that no debris or
foreign matter remains in the couplings or cooler bodies. Be certain interconnecting piping is clean to
avoid clogging the cooler passages.
Figure 5-5 – 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, page 50, 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.
