i
3.2.1 Main Unit Installation
• Find an easily accessible location where electrical
connections can be made and meter readings can be taken
from the floor level.
• Mount the Btu meter on a vibration-free surface. Avoid
sites such as the plenum of a fan coil, heat exchanger, or
other housings containing motors. Do not install the meter
in direct sunlight.
Use four screws for mounting the Btu meter. The mounting
surface must be structurally sound and capable of withstanding
a minimum weight of 40lbs (18kg). Use the following screws
for mounting.
• (4) Machine screws - HHMS .25-20 x 1.5”
• (4) Wood screws - FHLS .25 x 1.5”
• (4) Concrete screws - HHCS .25 x 1.5”
IMPORTANT NOTE
The ONICON System-10 BTU Measurement System is a custom calibrated system. Unless
specifically noted in writing by ONICON, ALL COMPONENTS (Btu meter, flow meter and
temperature sensors) share the same serial number and must be installed together as a system.
Mixing components from different systems will result in significant errors in calibration.
