2-IN-1 SENSOR (Temperature & Presence of Water)
Installation Instructions
PARTS:
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 fl ooding and fi tting leaks.
The 2-in-1 Sensor shall only be installed by a trained 
professional.
The sensor must be installed in the proper location for 
correct low water cut-off (LWCO) operation in 
accordance with the Boiler Manufacturer’s instructions.
The 2-in-1 sensor body is installed directly into the 
boiler wall tapped hole in place of an immersion well.
Carefully follow the outlined procedures for temperature 
sensor installation to ensure accurate water temperature 
sensing and effective control operation.
Make sure the plumbing for domestic hot water has anti-
scald valve protection.
Follow all applicable safety codes, rules and guidelines 
for installing an immersion well. Improper installation can 
result in the Boiler overheating.
