the Fuel Smart HydroStat control may

without any loss of function.

IMPORTANT

Make sure that the immersion well or Electro-Well™ is installed in the boiler manufacturer’s designated

temperature limit control tapping.

E:: If installing an Electro-Well, pipe sealing compound should be used. Teflon tape is not recommended.

IMMERSION WELLS

IMPORTANT: For proper operation of the low water cut-off function, there
must be a minimum of ½" clearance between the copper well tube and any
surface within the boiler.

See Electro-Well models on page 8.

NOTE: When installed on a standard immersion well, the “LWCO Active”
LED will not illuminate.

Fuel Smart HydroStat can be installed on an existing immersion well already in the boiler or on a Hydrolevel Electro-Well™

(sold separately). The low water cut-off function is automatically activated when installed on an Electro-Well™.

IMPORTANT: The control will not provide low water cut-off protection when installed on a standard immersion well.

NOTE: Do not use heat-conducting grease.
