1.6 MOUNTING
When choosing an installation site, be sure to check all clearances. Provide adequate clearance for the
enclosure door to be opened for wiring and service. The door is hinged on the left side. The LCD
display should be visible and accessible for the on-site operator. When using a solar panel, there
should be adequate clearance, and view of the sun should not be obstructed. Allow adequate clearance
and an obstructed location for antennas when using radios.
The Sensor is factory-mounted directly to the EF-Series Unit enclosure with four bolts. This mounting
uses a special coupler to join the Sensor to the four-bolt mounting pattern on the bottom of the
enclosure. See Section 4 for more information.
The Mounting section includes:
♦
Mounting the EF-Series Unit
♦
Mounting a Radio
♦
Accessing the Battery Compartment
1.6.1 Mounting the EF-Series Unit
Mounting of the EF-Series Unit can be accomplished using either of the following methods:
♦
Pipe mounted. The enclosure provides top and bottom mounting flanges with holes for
2-inch pipe clamps (U-bolts and brackets supplied). The 2-inch pipe can be mounted to
another pipe with a pipe saddle, or it can be cemented into the ground deep enough to
support the weight and conform to local building codes.
♦
Wall or panel mounted. Fasten to the wall or panel using the mounting flanges on the
enclosure. Use 5/16-inch bolts through all four holes. Mounting dimensions are given in
Figure 1-2.
CAUTION
Do not mount the EF-Series Unit with the Sensor supporting the entire weight of
the unit. Due to the weight of the unit with batteries and possibly an internally
mounted radio or cell phone, the unit does not meet vibration requirements unless
it is installed using its enclosure mounting flanges.
With either mounting method, the pressure inputs must be piped to the process connections on the
Sensor. For more information on process connections, refer to Section 4.
