
Carry out a general visual check of fittings, listen for a whistle which may identify
an air leak, and watch out for changes in indicated values during operation

Check the silica gel outlet moisture indicator:
o
Blue indicates an approximate dew point of -13°F
o
Pink indicates an approximate dew point of 32°F
o
Transparent indicates an approximate dew point of 59°F.

Check function by manually operating the automatic condensate drain on the
prefilter.
NOTE: Should the need for spare parts or service arise during work on the
adsorption dryer, then the dryer type and its construction must be


Check the differential pressure on the prefilter, which should not exceed 5 psi(d).
Values greater than this indicate that the filter must be changed (see paragraph
4.2).

Check the differential pressure on the afterfilter, which should not exceed 5
psi(d). Values greater than this indicate that the filter must be changed.

Check the pressure of the regenerating vessel during regeneration after
depressurization. Any back pressure caused by blocked exhaust mufflers will
show there. Back pressure on the regenerating tower should not exceed 3 psig.

Drain pilot filter/moisture indicator housing of any condensate.
