RECOMMENDED OPTIONS
1 . Guardian™Ultraviolet Monitor: Visually indicates the level of germicidal ultraviolet energy that penetrates the
quartz sleeve and the water within the water purifier. The ultraviolet monitor is capable of operating an optional
audio alarm and/or solenoid valve. The ultraviolet monitor will detect reduction of ultraviolet levels due to:
• Fouling or deposits on the quartz sleeve.
• Poor ultraviolet transmission through the water; color, turbidity, and organic or other impurities in the water
can reduce or interfere with the transmission of ultraviolet rays.
• Lamp outage, component or power failure.
• Depreciation of the lamp output due to usage or other cause. Lamp output gradually depreciates with use.
Lamp replacement is recommended once each year.
• Use of the Guardian™Ultraviolet Monitoris recommended by the U. S. Public Health Service “Criteria for
the Acceptability of an Ultraviolet Disinfection Unit.”
2. Sentry™Safety Sensor: Pilot lamps provide constant visual monitoring of normal operation. In the event of
power or lamp failure the safety sensor indicates an alarm condition. The safety sensor is capable of operating an
optional audio alarm and/or solenoid valve.
3. Steralert™:Lamp Status Alarm produces a high pitched, pulsed tone when the water purifier is no longer
functioning due to lamp or power failure.
4. Flow Control Valve:Limits water flow to the rated capacity of the purifier. The flow control valve is located in
line prior to the water purifier, and should be protected from ultraviolet exposure by the use of a 90-degree elbow
fitting between the flow control valve and the water purifier.
5. Audio Alarm: Activated by the Ultraviolet Monitor or Safety Sensor, alerts the user to any malfunction detected.
6. Solenoid Valve:Operated in conjunction with the Ultraviolet Monitor, Safety Sensor or Time Delay Mechanism,
this valve prevents water flow through the water purifier when an abnormal condition is detected or in the event of
power failure.
7. Elapsed Time Indicator: A non-resettable display of the water purifier operating hours. Useful for scheduling and
recording maintenance and lamp replacement.
8. Time Delay Mechanism: Provides a 2-minute warm up period during which the ultraviolet lamp achieves its full
germicidal output before the water is allowed to flow through the water purifier. The time delay mechanism is used
in conjunction with, and is electrically connected to the Solenoid Valve.
9. Wall Mount Kit: Stainless steel wall brackets provide quick and easy installation and professional finish.
Pre-drilled and ready to install. Optimizes free air circulation to cool ballast housing.
10. Quantum Thermal Optimizer: Thermal relief valve used to help regulate the water temperature inside the water
purifier's disinfection chamber. Since the relative ultraviolet output, of a germicidal lamp, is affected by
temperature it is important to keep the lamp's temperature within the peak output temperature range.
