SECTION 3.0 INSTALLATION
The System-10 BTU Meter should be installed by experienced contractors with related knowledge and experience in
assistance.
The installer should use good trade practices and must adhere to all state and local building or other applicable codes.
3.1 SITE SELECTION
3.1.1 The System-10 BTU Meter
3.1.2 The Flow Meter
Careful attention to the site selection for the system components will help the installers with the initial installation, reduce
start-up problems, and make future maintenance easier.
following.
IMPORTANT NOTE
Proper site selection is critical to the performance of this BTU meter. Both the ow meter and the two temperature
sensors must be properly located within the piping system in order to ensure an accurate energy measurement.
level. Mount the System-10 enclosure on a vibration free surface. Avoid locations such as the plenum of a fan coil, heat
exchanger or any housing that may contain electric motors or other strong sources of electrical interference.
3.1.3 The Temperature Sensors
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.

3.2.2 Thermowell Installation
IMPORTANT NOTE
It is important that no dirt or other foreign material be allowed into the thermowells as this could aect the
thermal response of the system.
Dry tap thermowells are for new construction or scheduled shutdown. The most common installation methods are
thermowell installations. Consult ONICON for special applications.

WARNING
SYSTEM MAY BE UNDER HIGH PRESSURE. Be sure to hold the conduit box rmly by hand before slowly loosening
the position clamping nut when installing, adjusting or removing the thermowell. Failure to do this will allow
the pressure to suddenly and rapidly force the thermowell from the pipe, potentially causing serious injury. The
thermowell could also be damaged or break apart causing a break in the water seal with the resultant loss of
large amounts of water.
Insertion of the Hot Tap Thermowell
1.
thermowell should ensure adequate footing for the force required prior to opening the valve.
2. Thread the hot tap adapter into the valve. Firmly grasp the wiring enclosure, loosen the position clamping nut, open
3.
release the wiring enclosure until the position clamping nut has been tightened.
CAUTION
Excessive vibration can damage the thermowell. Insert the thermowell to the proper depth using gauge supplied as
shown. Reduce the insertion depth as necessary if strong vibrations are felt during insertion, making certain that the
tip of the thermowell remains fully in the ow stream.
CAUTION
DO NOT OVER TIGHTEN THE POSITION CLAMPING NUT. If uid leaks, do not attempt to correct by tightening this
nut further. An internal o-ring seals the uid. Contact ONICON for assistance in the event of a leak.

Removal Of The Hot Tap Thermowell
WARNING
Maintain a rm hold on the wiring enclosure until the thermowell is completely withdrawn and the valve is closed.
IMPORTANT NOTE
Rotating the thermowell as you slowly withdraw it through the valve will ensure that the lower tip is fully withdrawn
and completely free of the valve. If resistance is felt when closing the valve, open valve fully and rotate the well as
you pull it further out of the pipe.
1.
establish safe footing prior to loosening the clamping nut. The force pushing out against the thermowell is the same as
the insertion force calculated above.
2.
withdraw the thermowell from the pipe. After the thermowell is completely withdrawn, carefully close the isolation
valve.

sensor.
• Apply a thin coat of thermal compound to the temperature sensor, and gently insert the temperature sensor all the way
into the thermowell until it contacts the bottom of the cavity.
•
• The thermowell completely seals the plumbing system without the retainer nut. The only purpose for the nut is to keep
the sensor from losing contact with the bottom of the thermowell cavity.
IMPORTANT NOTE
Cable length is specied at time of order. Cable provided for temperature sensors is #22 gauge twisted shielded pair.
Additional cable may be added in the eld if necessary, but must be of twisted shielded pair construction.

WARNING
Disconnect main power before proceeding.
CAUTION
This product must be connected to earth ground for proper operation. Failure to do so may result in erratic operation.
Connect the protective earth wire to the lug located in the lower left hand corner of the motherboard.
