3.
At this time, make the drain port connection. For this step, there are two
options, as desired, depending on the installation location and function.
Refer to Figure 4. Either carefully connect the bronze muffler to the fitting
on the drain port (to serve as a moisture diffuser), or connect an 1/8” NPT
male end barbed hose fitting to the drain port fitting, attach a hose, then
route the hose to a facility drain.
Figure 4. BASE OF NEMA ENCLOSURE.
NOTE
If using the bronze muffler, do not force it into place as doing so might strip the
threads. If the muffler does not screw onto the drain port fitting easily, carefully
unscrew it, reseat it, try screwing it in again. If using a hose connected to the
drain port fitting, make sure the hose points down. The unit design prevents
freezing inside the enclosure. It is the customer’s responsibility to ensure that
the added hose line does not freeze outside the enclosure. Finally, if using a
hose, install a small filter or screen at the end of the hose to help keep bugs from
getting up inside the hose.

Connect and secure the dry air supply line to the 1/8” NPT female
connection at the bottom of the unit using the appropriate fitting.
