MOUNTING THE CONTROL
STEP 1 Two mounting positions
are available on the back of the control
(Fig. 1). Select which of the two positions
(2 knockouts) is best for the location of
the control. Remove the knockout.
STEP 2 Place control on the well.
While holding box against well nut,
tighten well clamp screw. (Fig. 2)

NOTE: In the case of space restrictions, the Fuel Smart HydroStat control may be mounted in a horizontal orientation without any
loss of function. Hydrolevel recommends vertical mounting, when possible, for proper orientation of LED display.
REMOTE MOUNTING KITS are available separately for mounting the Fuel Smart HydroStat control box in a remote location.
Each kit includes mounting hardware and a remote sensor. See page 16 for kit options.
STEP 3 Insert sensor ALL THE
WAY into well through the knockout (A
or B) you have chosen. (Fig. 3)
IMPORTANT Make sure that the immersion well or Electro-Well™ is installed in the boiler manufacturer’s designated
temperature limit control tapping.
N NO OT TE E:: If installing an Electro-Well™, pipe sealing compound should be used. Teflon tape is not recommended.
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 cop-
per well tube and any furnace within the boiler.
See Electro-Well™ models on page 15.
When installing on a standard immersion well, the LWCO function should
be turned off (see page 10 for instructions). A buildup of heat transfer
grease or other coatings in older wells can interfere with continuity between
the sensor and the well causing a false low water shutdown. Turning off the
LWCO function will prevent this from occurring.
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™.
