Boreal Laser Inc. GasFinderMC Operation Manual— Installation July 17th 2017
Section 3. Installation
GasFinderMC - CCU
The GasFinderMC CCU fi ts into a standard 19” (485mm) wide rack and is 3U (132mm) high.
Small rubber feet on the bottom of the unit increase the height to 140mm. These feet can
easily be removed if space is limited, although this is not recommended as it restricts airfl ow
for cooling.
If the rack is mounted to a wall or access to the rear is diffi cult, a hinged rack mount is
required. This allows the CCU to swing outwards and makes the cable connections, which
are all at the rear, much easier to install. The cables should be routed on the hinged side of
the cabinet in order to minimise their movement.
Accessory modules are available for 4-20mA output, RF Barrier protection and Dry Contact
Relay output. These modules are described in their own manuals.
A schematic illustrating the cable connections is shown in the drawing section at the rear of the
manual.
Caution: The infrared laser output from the GasFinderMC has very low
power (conforms to Class 1 as per IEC 60825-1) and will not damage
eye tissue.
However, it is the recommendation of Boreal Laser Inc. that, as with
ANY LASER SYSTEM, the user/ operator should avoid staring directly
into the output aperture of the instrument.
Note that the laser beam is infra-red and is not visible to the eye.
Safety Issues.
Tools Required: electrician’s hand tools.
The Boreal Laser Diagnostic and Troubleshooting Kit for MC Systems is recommended.

Sequence of the Installation: the preferred sequence is to install the Central Control Unit
(CCU) and the retrorefl ectors fi rst and then the Remote Heads. This ensures that when the
Remote Heads are installed they can be aligned at the same time.
