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 with Integrated SVRSNow Available - 2
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.
