4.2 PIPING AND CONNECTIONS
Connect the inlet and outlet piping to the dryer using the markings on the dryer as a guide. Pipe size for dryer is
specified in the specification table. Piping should be full flow if possible with the least amount of turns, bends, or
reductions. If the dryer is connected to a machine with excessive vibration, flexible connections should be used to
isolate the dryer from the rest of the system. Use Figure 4.2.1 as a suggested guide for the installation of system
components.
Use di-electric unions to isolate copper from iron piping and reduce possibility of electrolytic action on pipes and other
iron components.
All pipe should be deburred and threaded to a proper depth and length before installation. Threads should be
inspected for cleanliness and depth of cut. Good quality pipe compound should be used in the makeup of joints to
ensure a good, airtight fit of piping components.
Pipe should be anchored separately from the dryer. At no time should the dryer be expected to support the weight or
load of the pipe. Acceptable pipe mounting devices would be unistrut supports anchored to walls, hangers suspended
from ceilings, or pedestals mounted from the floor. Be sure all pipe installation conforms to all building and fire codes.
