IMPORTANT NOTE
ONICON BTU meters are
precision measuring devices
that must be installed
according to the instructions
contained in this document
in order to maintain their
accuracy and reliability.
For Use with Kit: INSTL0501-TSC & INSTL0502-TSC
Please read entire manual before installing the meter.
The two temperature sensors must be located in such a manner
as to accurately measure only the temperature of the supply line
entering and the return line leaving the portion of the piping
system for which the energy measurement is being made.
If possible, nd an easily accessible location where wire
connections can be made from oor level. This will facilitate any
future service.
One temperature sensor thermowell will need to be placed in the same pipe as the mounting
brackets. If it is an immersion thermowell, it must be located on the downstream side of the mounting
brackets.
The downstream distance between the thermowell and brackets should be at least ve (5) pipe
diameters, leaving enough clearance to remove either sensor from the pipe without interference from
the other sensor.
IMPORTANT NOTE:
Place the temperature sensors away from strong sources of electrical noise that might aect the
performance of the sensors.

3. Apply a thin coat of thermal compound to the temperature sensor, and gently insert the
temperature sensor all the way into the clamp-on thermowell.
4. Apply thermal compound to the heat sink and install the clamp-on thermowell on to the pipe
using the pipe strap as shown.

5. Connect the Signal (+) and Reference (-) wires from the transmitter to the F-4300 BTU meter
through the strain relief. Be sure to observe the polarity of the connection, positive to positive
and negative to negative. Shield wires should be connected at the F-4300, but left open at the
temperature sensor transmitter.

6. Tighten the strain reliefs and reinstall the junction box cover. Once the thermowells and sensors
are fully installed and tested, insulate the thermowells and the pipe to complete the installation.
