3.2 MECHANICAL INSTALLATION

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 oor 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”

specically noted in writing by ONICON, ALL COMPONENTS (Btu meter, ow 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 signicant errors in calibration.
