4. Spacer Installation
If spacing adjustment is
necessary to accommodate
installation, install a spacer on
the outlet flange. The spacer
should consist of a spacer,
gaskets, bolts and nuts. Fit
gaskets to both sides of the
spacer between the
M-COS
outlet and the pipe flange.
Fasten with bolts and nuts.

7. Trap Outlet Piping
For ease of maintenance, installation
of a union connection is
recommended for the trap outlet pipe.
Connect the outlet pipe to a
condensate return line, or extend it to
a trench. In the case of the latter,
make sure the end of the pipe is
above the waterline.
(Dirt and water may otherwise be
sucked up by the vacuum formed
during trap closure and system
shutdown.)
