Installing the Indirect Water Storage Tank Sensor
(Included with the Hydro Kit; Replacement No. EBG61325701; For Those Applications With An Indirect Water Storage
Tank)
• Always shut the power off before installing the sensor. There is a risk of electric shock, physical injury and / or death.
• Never operate the Hydro Kit outside of the operational parameters as outlined in this manual and the product specifications. There is a
risk of electric shock, fire, physical injury and / or death.
• Never touch wiring or install the sensor with wet hands. There is a risk of electric shock, physical injury and / or death.
• Do not install the sensor if the indirect hot water storage tank contains water. If the indirect water storage tank has water in it, isolate
the water circuit by closing the shutoff valves, and drain the tank until empty. There is a risk of electric shock, physical injury and / or death.
• Never operate the Hydro Kit outside of the operational parameters as outlined in this manual and the product specifications. There is a
risk of product malfunction and / or damage.
• The sensor is not necessary if the Hydro Kit will be used in an application that does not include an indirect hot water storage tank.
• Locate the indirect hot water storage tank so that the 39 foot (12 m) cable of the sensor reaches both the Hydro Kit PCB board and the sen-
sor well.
•
Depending on the current draw of nearby wiring, the minimum clearance distance will have to be increased. For more information regarding
power wiring / communications cable clearances, see the Wiring section.
Sensor Installation (See Previous Page for Sensor Well Installation)
1. If the indirect hot water storage tank includes an existing sensor well that can accommodate
the 1/2" MPT connection sensor, use it. If it does not include a sensor well, see the sensor
well installation instructions on the previous page.
2. Remove the sensor and cable from the well. Loosen and remove the keeping nut at the entry
of the well housing, and remove the sensor from the well by gently pulling on the sensor
cable. Slide the keeping nut up the sensor wire so it will not get misplaced. Threads must
face the sensor bulb.
3. Apply a generous portion of thermal paste to the sensor and in the well. Use enough to fill
the spaces between the sensor head and the sensor well walls.
4. Insert the sensor all the way into the well until it bottoms out. Completely fill any remaining
air gaps with thermal paste.
5. Slide the keeping nut down the sensor cable and thread it on the sensor well.
