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 12 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.

NNOOTTEE::

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 12.

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.
