Checking the Dewpoint
It is a good idea to monitor the dewpoint performance of your dryer periodically
with a calibrated portable dewpoint monitor, to ensure it is performing at
maximum capacity. Even if your dryer has a dewpoint readout, comparing it
to a portable instrument periodically will confirm that the dewpoint sensor and
readout is performing properly.
To check dewpoint:
1 Connect your portable dewpoint meter to the
dewpoint check port of the dryer.
2 Turn on the portable instrument, and ensure
there is positive airflow through the sensor.
3 Monitor the readout and allow ample time for it to stabilize before discon-
necting the portable dewpoint monitor. Some dewpoint monitors require a
substantial amount of time for residual moisture to be purged from the sensor.
4 In the event the dewpoint in not satisfactory, refer to the Troubleshooting
section of the manual, under Process Dewpoint alarm for DC2.
Alternate Procedure: (for dryers with no dewpoint check port)
1 Stop dryer and allow it to cool.
2 Swing open or remove the left side panel. See Installation section entitled,
Opening the dryer doors (W1600-5000).
3 Remove the 1/8 inch NPT pipe plug at the process air outlet on the bottom
manifold of the desiccant wheel assembly.
4 Connect a portable dewpoint meter to the hole from which the plug was just
removed.

NOTE: Portable dewpoint
monitors purchased from Conair
are provided with a male
connector that plugs into the
dewpoint check port. If you
purchased your portable
instrument elsewhere, the male
connector is available through
the Conair parts department.
NOTE: The dewpoint check port
was not included on the initial
release of these dryers. It can
be added easily. Contact the
Conair parts department or
follow the alternate procedure.
