IMMERSION WELLS
When installed on an Electro-Well™ (sold separately), the Low
Water Cut-Off function is automatically activated. Heat transfer
grease should not be used. NOTE: For proper operation, there must
be 1/2" clearance between the copper well tube and any furnace
within the boiler.
See Electro-Well™ models on page 15.
NOTE: When installed on a standard immersion well, the “LWCO
Active” LED will not illuminate.
Fuel Smart HydroStat can be installed on a Hydrolevel Electro-Well™ or on an existing immersion well already in the boiler.
IMPORTANT: The control will only provide low water cut-off protection when installed on an Electro-Well™.
