3.5.2 EXHAUST CONNECTION
CAUTION
Connect the exhaust fitting to a suitable vent outside the monitor area.
Connect a ¼” OD vent line to the EXHAUST fitting on the monitor. This line must
be vented outdoors or to an appropriate discharge system capable of handling
ozone. Local regulations regarding the discharge of ozone to the atmosphere must
be observed. Note that the monitor may be equipped with an internal ozone scrubber
for removal of ozone from the exhaust stream. For safety reasons, the exhaust port
must still be vented appropriately.
3.5.3
SAMPLE CONDITIONER OPTION
The Sample Conditioner option is a coalescing filter and a permeation gas dryer,
designed for high-humidity environments where the sampling gas has been
saturated with water vapor and may contain small amounts of condensed water.
This coalescing filter removes not only liquid, but also particulates with a Teflon™
filter element.
Due to the additional volume added by the coalescing filter, there is an exception to
the Response Time specification for the 480L: when equipped with the Sample
Conditioner option, a 480L instrument’s Response Time is <60 seconds to 95%.
CAUTION
The Sample Conditioner will NOT protect the unit from
damage by large amounts of liquid, such as that ingested
through immersion of the sample line.
Furthermore, it is important to closely track the amount of
water accumulating in the Coalescing Filter after the
monitor has been installed and running. If excessive
condensation is occurring in the sample lines leading to
the monitor, then heat-traced lines should also be used to
minimize condensation.
The Sample Conditioner option includes a Permeation Gas Dryer, which is available
as an alternate option (described next) if humidity is the only concern and there is
no risk of condensation.
