The Signet 4630 and 4632 Systems are EPA 334.0 Compliant.
Description
The Signet Chlorine Analyzer Systems are integrated, all-in-one chlorine panel systems
designed to measure Free Chlorine or Chlorine Dioxide in drinking water and clean, fresh
water treatment applications.
This manual includes the 4630 Free Chlorine and 4632 Chlorine Dioxide Analyzer Systems.
Features:
• EPA 334.0 Compliant: The 4630 Free Chlorine and 4632 Chlorine Dioxide systems can
be used for reporting chlorine residuals in accordance with EPA Method 334.0.
• Complete chlorine analyzer system allows quick setup and easy installation. Connect
to a water source and plug it in.
• Unique integrated clear fl ow cell combines sensors, fl ow regulator, fi lter and variable
area fl ow indicator in one compact unit.
• Built-in variable area fl ow indicator facilitates fl ow rate confi rmation at a glance.
• Integrated fl ow regulator with removable fi lter accepts inlet pressures of 1 to 8 bar
(15 to 120 psi) while maintaining constant fl ow and minimal pressure to the sensors.
• Water fl ows vertically into sensor tip, eliminating bubble entrapment. Raised exit in fl ow
cell sensor chamber ensures sensors stay submerged even when system and fl ow is
turned off.
• Flow cell accommodates two sensors; one chlorine and an optional pH sensor.
• Automatic pH and temperature compensation or manual pH value input capability for
accurate free chlorine readings.
• Easy viewing of the transmitter via the bright backlit LCD display.
• Moisture-proof NEMA 4X wiring enclosure.

Safety
CAUTION!
1. Follow instructions carefully to avoid personal injury.
2. Do not exceed the maximum pressure or temperature specifi cations.
3. Mounting the Chlorine System in an outdoor box, in areas with elevated temperatures,
may cause damage to the system if the enclosure's internal temperature exceeds the
temperature specifi cation of the Chlorine Analyzer.
4. Do not alter product construction.
5. For use with clean fresh water only.
6. Disconnect AC power before opening wiring enclosure.
7. This panel system uses AC voltages. Wiring should be done by qualifi ed personnel only.
