INITIAL PREPARATION AND INSTALLATION
INSTALLATION PERSONNEL
Installation of the PCA 300 and PCA 301 family of Chlo-
rine Analyzers should be undertaken by persons with technical
knowledge of the dangers associated with chemical exposure
and electrical shock.
Hanna Instruments assumes persons performing the instal-
lation tasks are aware of the appropriate safety procedures.
Review the Material Safety Data Sheets (MSDS) before han-
dling the supplied chemical reagents.
LOCATION OF THE INSTRUMENT
Analyzer Location
Locate the analyzer as close as is reasonably possible to
the point where the sample is withdrawn from the product
stream (referred to as the “sampling point”). This practice
will minimize the amount of time it takes for the sample to
flow to the analyzer from the sampling point. The result is
improved response time of the analyzer to changes in Chlo-
rine contents.
The instrument should be mounted indoors, out of direct
sunlight. Instrument operating temperature is 5 to 40°C
(41 to 104°F).
Sampling Point Location
Locate the sampling point to obtain a truly representative
sample from the product stream. For example, be sure the
sampling point is well downstream from a Chlorine feed.
This assures that adequate mixing and reaction of the
Chlorine before a sample is extracted.
HYDRAULIC CONNECTIONS
Note Hydraulic connections should be installed only by qualified
personnel to assure conformity to applicable plumbing codes.
Sample Line Installation
Sample lines of 3 mm (1/8") ID tubing are recommended to
keep the sample volume in the tubing to a minimum. This
reduces lag time for the sample flow from the sampling point
to the instrument. In any case note that sample should reach
the measuring cell in less then 100 seconds.
