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 11.

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™.

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.

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.

NOTE:

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

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.

IMPORTANT – Sensor must be inserted all the way into the well for proper operation.

CORRECT INCORRECT

The Electro-Well can be identified by the black electrical insulator

or, if installed, by the groove cut into the hexnut.
