DESCRIPTION
1.1 GENERAL INFORMATION
The Sentry Aqua Guard system is a low pressure, high output amalgam, ultraviolet light
sterilizer designed for commercial swimming pool applications. The Sentry Aqua Guard
is capable of sterilizing and oxidizing up to 1141 gallons per minute of water. The
system operates at light wavelengths of 254nm for sterilizing and 185nm for oxidizing.
The Sentry Aqua Guard is designed for commercial service and can be run 24 hours a
day. The Sentry Aqua Guard components are outlined in Figure 1:

1.2 PRINCIPALS OF OPERATION
UV Light Chamber (See Figure 1)
The UV Light Chamber is made from highly polished 316L stainless steel or 316L
stainless steel lined PVC. Quartz sleeves separate the low pressure, high output
amalgam germicidal lamps from the water. The water to be treated flows into the
bottom of the chamber. Once in the chamber, the germicidal bulbs produce a minimum
3-log reduction in pathogens. The water is then returned to the source.
Power Supply (See Figure 1)
The power supply provides the current to start and maintain the germicidal lamps. A
visual indication of bulb output is displayed on the face of the power supply and a
counter is located in the power supply to display hours of operation.
1.3 GENERAL SPECIFICATIONS AND SIZING GUIDELINES
This unit has demonstrated an ability to provide three log inactivation of Enterococcus
faecium and Pseudomonas aeruginosa. This unit has not demonstrated an ability to
provide three log kill or inactivation of Cryptosporidium parvum. This product is
designed for supplementary disinfection and is intended for use with appropriate
residual levels of EPA registered disinfecting chemicals. Specific residual levels of EPA
registered disinfecting chemicals may be required by the regulatory agency having
authority.

SIZING GUIDELINES
Sentry Aqua Guard UV Sterilizers will effectively treat water up to the maximum rated
flow for each size unit (END of lamp life). See flow calculator on the next page.
UV sizing must comply with local codes. Please contact your local health department
for specific requirements or contact your local ChlorKing representative for assistance.

9
The chart and temperature compensation formula below are used to determine the
maximum system flow rate for satisfactory system performance.
Select the chart for your UV model and a flow rate from the chart based on the
% Transmittance (%T) of the pool. If you are unsure of the %T, use 95%. The flow rate
must then be compensated for temperatures less than 88°F. Determine the average
pool temperature and use the formula below to determine the maximum flow rate.
avT = average pool temperature
((100 - ) 88° - avT) / 100) x GPM
Example for model SAG120A120PVC, 95%T, and average pool temperature of 84°:
((100 - ) 88° - 84°) / 100) x 61 GPM
((100 - ) 4) / 100) x 61
