Dwyer Instruments Magnehelic A-286 Series Specifications-Installation And Operating Instructions

The new mounting flange can be used on any Dwyer Instruments, Inc.
gage that possesses a 4-1/2˝ (115 mm) diameter housing. The flange is
secured to the gage behind its bezel with three set screws. The set
screws hold the gage tight in place. The gage/flange can then be
attached to a surface or panel with a drill and the supplied mounting
screws. The flange's three mounting holes follow the industry standard
mounting pattern. The flange is made of a robust plastic composite and
comes with three pre-installed set screws, an allen wrench for tighten-
ing and three flange mounting screws.

INSTALLATION

Cut out a circular hole using the template on this manual. The diameter
hole size depends on tightness of set screws securing the flange to the
gage. Typically, a sufficient flange tightness will produce a required
diameter cut-out between 5 1/16˝ – 5 1/8˝. See the included template to
locate on your panel this proper size diameter cut-out in relation to the
locations of the three mounting screws.
Next, alternating between the three set screws, use the included allen
wrench to turn each set screw 1/4 to 1/2 turns at a time to ensure an
even tightness so one screw doesn't cause the flange to bow.
To properly secure flange to gage, 1 to 1.5 full revolutions of each set
screw will be required.
Last, install flange with secured gage to wall or panel using the three
included mounting screws.
