Beckett 7600 manual Explosion Burn and Scald Hazards, 8 hex

Page 8

Installing the 2-in-1 Sensor

Do not use in steam applications. For use in

hot water boilers or water heaters only. Do not use outside of the intended use and specifications.

Leak, Burn, and Scald

Hazards

Incompatible thread sealants could severely damage the sensor threads.

yOnly use Teflon® Tape or Rectorseal® No. 5® (soft-set).

yDO NOT use any anaerobic fast-setting sealants such as, but not limited to, Loctite®, Leak Lock®, Permatex®, or Gasoila®.

yCall RWB Technical Services at 1(800)645-2876 to confirm, if unsure.

For proper operation, there must be a secure electrical bond

between the green sensor wire from the sensor and the boiler metal vessel in direct contact with the boiler water. Failure to secure an electrical bond will result in the AquaSmart locking out and displaying, “LOCKOUT - LOW WATER”.

Explosion,

Burn and Scald Hazards

Excessive water temperatures could cause explosion, burns, scalding, pressure relief flooding and fitting leaks.

yThe 2-in-1 Sensor shall only be installed by a trained professional.

yThe sensor must be installed in the proper location for correct low water cut-off (LWCO) operation in accordance with the Boiler Manufacturer’s instructions.

yThe 2-in-1 sensor body is installed directly into the boiler wall tapped hole in place of an immersion well.

yCarefully follow the outlined procedures for temperature sensor installation to ensure accurate water temperature sensing and effective control operation.

yMake sure the plumbing for domestic hot water has anti-scald valve protection.

yFollow all applicable safety codes, rules and guidelines for installing an immersion well. Improper installation can result in the Boiler overheating.
