SECTION 3.
INSTALLATION
3.1
General Information for Installation
Every detail of installation location is critical to ensure overall system performance and effectiveness.
Strict compliance and considerable thought must be given to every detail of the installation process,
including, but not limited to the following:
•
Regulations as well as local, state, and national codes that govern the installation of gas detection
equipment
•
Electrical codes that govern the routing and connection of electrical power and signal cables to gas
detection equipment
•
The full range of environmental conditions to which the detectors will be exposed (refer to section 6:
Sensor Principle on page 32 for more information on ambient conditions and cross-sensitivity)
•
The physical characteristics of the gas or vapor to be detected
•
The specifics of the application (e.g., possible leaks, air movement/draft, etc.)
•
The degree of accessibility required for maintenance purposes
•
The types of optional equipment and accessories that will be used with the system
•
Any limiting factors or regulations that would affect system performance or installations
•
Wiring details, including the following:
o
Wiring must be connected as indicated in this manual.
o
The wiring for power and relays must be selected and fused according to the rated voltages,
currents, and environmental conditions.
o
If stranded conductors are used, a ferrule should be used.
o
A switch or circuit breaker must be included in the installation.
o
The switch or circuit breaker must be suitably located and easily reached.
o
The switch or circuit breaker must be marked as the disconnect device for the equipment.
3.2
Mechanical Installation
•
The detector fits in most 2-gang electrical back boxes (not included) (See Section 10 for details on
the custom UK version of the MVR-300)
•
The detector must be accessible for maintenance (e.g., adjustment)
•
The access pathway of the refrigerant gas to the sensor must not be obstructed
•
The detector should be installed about 4 to 6 inches (100 to 150 mm) above the floor level
