The Guardian® line of pool and spa motors equipped with the latest
version of eMod® technology. With increased memory capacity and other
performance-enhancing features, theGuardian is Safety Vacuum Release
System (SVRS) compliant for suction lift applications.
Suitable
for both commercial and residential use, the Guardian design reacts
faster to fullbodysuction entrapments and is less prone to nuisance
trips. Guardian motors are ETL listed to theASME/ANSI A112.19.17 or ASTM
standard F2387 and comply with requirements for SVRScontained in the
Virginia Graeme Baker Pool and Spa Safety Act of 2007.
"The
recent upgrades on the newest Guardian motors culminate in an SVRS
device that iseconomical, easy to install, requires minimal maintenance,
and passes the ASME standard," WarrenDoney, market manager of A. O.
Smith Electrical Products Company, observed. "The end result is
atechnologically superior approach to meeting government-mandated SVRS
requirements without theexpensive price tag or arduous installation
process.”
Unlike a conventional SVRS, which is
typically an add-on device, Guardian load-sensingelectronics are fully
integrated into the pool and spa motors. Guardian motors require no
externalparts or connections to the existing plumbing or electrical
system, making installation as easy as of anew motor.
"We
think that the industry and the consumer will embrace this technology
because a poolowner can upgrade their in-ground system simply by
replacing their existing pump or motor with oneequipped with Guardian
technology," Doney pointed out.-more Newly Upgraded Guardian® Motors

As with the
original eMod technology and earlier Guardian designs, the new
Guardianautomatically calibrates to the specific hydraulic and
filtration characteristics of the pool at initialstart-up. The
electronics constantly monitor the input power of the motor and detect
any changes inthe operating conditions of the pool such as clogged
drain, jammed pump or locked rotor, drops ininput power (that can cause
"dry running" of the pump), or suction entrapment. Any time
theelectronics detect these conditions, the motor and pump shut off
automatically, avoiding damage tothe pump, motor, or pool system itself.
"The
motor is designed to fail in the "off" position," Doney explained,
"meaning if theelectronics are defeated or tampered with, the motor
shuts off.” The load-sensing circuitry isprotected by an
impact-resistant, high-density plastic housing. The protective
compartment isattached directly to the motor and resists weathering,
ultra-violet light, and is tamper-proof. Otherkey features include:•
Increased memory capacity
- Improved push-button controls and indicator lights
- Indicator light fault codes allow for remote trouble-shooting
- Auto restart
- Improved by-pass mode available whenever there is power to the motor
- Ability to re-start motor in by-pass mode from a fault status
- Increased pressure range of operation for reduction or elimination of nuisance tripping
- ETL listed to ASME A112.19.17 Standard for suction lift applications and VGB compliant
- Full body entrapment release protection
- Compatible with all flow rates
- Detects clogged or blocked filters and shuts down the pump
- Shut-off in the event of dry, blocked, or jammed pump conditions, locked rotor, loss of prime,or abnormal voltage variations
- Facilitates
no main drain pool designs in place of an equalizer line – Guardian
shuts off themotor/pump when the water level drops below the skimmer
- Reduces pump, motor, and seal damage-more NewlyUpgraded Guardian® Motors with Integrated SVRSNow Available - 3
"While
A. O. Smith Guardian motors equipped with load-sensing technology are
an important part of a safe pool environment, they do not solve the
total entrapment issue by themselves," Doneycautioned. For the full
guidelines on entrapment refer to the Association of Pool and Spa
Professionals web site, www.apsp.com or the U. S. Consumer Product
Safety Commission at www.cpsc.gov.
