4.6 INSTALLING THE PURGE MUFFLER
The muffler was shipped separately. It should NOT be installed until
the dryer has been operated for several hours. From desiccant instal-
lation, some dust may be present in the desiccant towers. Operating
the dryer with the muffler installed immediately after the towers have
been filled with desiccant or at initial start up may cause the muffler to
clog.
IMPORTANT
The dryer must be operated for several hours without the muf-
fler after the towers have been filled with desiccant. This will
prevent the muffler from becoming clogged.
