Please notify ONICON if any of these items are missing.
• The D-100
Remove the D-100 from the shipping carton and inspect it for physical damage. When
you complete the external inspection, open the enclosure and inspect the interior for signs
of damage in transit. Also, confirm that the circuit boards and connectors are all securely
seated in their sockets. Please notify ONICON immediately if you find any discrepancies.
• The Flow Meter
The flow meter intended for use with this display came complete with an instruction
manual. Please refer to the flow meter instruction manual for detailed information
regarding the installation, commissioning and operation of the flow meter. Each D-100 is
calibrated to a specific flow meter, the two must be used together as a system. If the flow
meter and display were purchased together, the serial number on the flow meter will be
located on a label inside the D-100.
SECTION 3.0: INSTALLATION
The D-100 should be installed by qualified individuals with knowledge and experience in the heating,
cooling, and fluid metering fields. ONICON will be happy to assist with technical recommendations
and to provide guidance by telephone and/or email. On-site field engineering, installation and service
are also available at an additional cost. The installer should use good trade practices and must adhere
to all state, federal and local building codes.
3.1 SITE SELECTION
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. For example,
do not install the flow meter where it will be difficult for personnel to perform periodic
maintenance and calibration. When selecting a site for mounting the system components,
consider the criteria under Section 1.5 WORKING ENVIRONMENT, as well as the following:
The D-100
Find an easily accessible location where wire connections can be made and meter readings
can be taken from floor level. Mount the D-100 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.
The Flow Meter
Choose the location with the longest straight run of unobstructed pipe. Please refer to the
flow meter installation manual for specific information regarding the straight run
requirements for the flow meter used with this display.
