INITIAL PREPARATION AND INSTALLATION
INSTALLATION PERSONNEL
Installation of the PCA 310-330 Chlorine, pH, ORP and
temperature analyzers should be undertaken by persons with
technical knowledge of the dangers associated with chemical
exposure and electrical shock.
Hanna Instruments assumes that persons performing the in-
stallation tasks are aware of the appropriate safety procedures.
CAUTION: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point where the sample is withdrawn from the product stream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).
The instrument should be mounted indoors, out of direct sun-
light. 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 and acid / alkali
feed. This assures that adequate mixing and reaction of the
Chlorine and acid / alkali 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
Direct routing of sample lines is recommended.
If the large process pipes are horizontal, taps should be in-
serted vertically in the middle of the pipe to avoid pulling
sediment from
the bottom or
air bubbles
from the top
of the pipe
into the sam-
ple line.
