Installation
Controller Mounting Orientation
Mount the controller with the housing vertical, as
shown in figure 2–1, so the vent points down.
Pipestand Mounting
Refer to figure 2–2. Pipestand mounting parts are pro-
vided to mount the controller to a 2-inch (nominal)
pipe. Attach a bracket (key 68) to the controller with
cap screws (key 66) and lock washers (key 67). Attach
two clamps (key 69) to the bracket and fasten the con-
troller to the pipe.
Panel Mounting
Using the dimensions shown in figure 2–3, cut a hole
in the panel surface. Slide the controller into the hole
and attach the bracket (key 68) to the rear of the con-
troller using three cap screws (key 66) and lock wash-
ers (key 67). Tighten the screws (key 70) to seat the
case snugly and evenly against the panel surface.
Wall Mounting
Using the dimensions in figure 2–4, drill holes in the
wall to align with the four holes in the bracket (key 68).
If the tubing is to run through the wall, drill a hole in
the wall large enough to accept the tubing.
Mount the controller to the bracket using three cap
screws (key 66) and lock washers (key 67). Attach the
bracket to the wall, using suitable screws or bolts.
Actuator Mounting
Refer to figure 2–1. A controller specified for mounting
on a control valve actuator is mounted at the factory. If
the controller is ordered separately for installation on a
control valve actuator, mount the unit as described in
this section. Mounting parts vary for different actuator
types.
Attach the mounting bracket to the actuator yoke with
cap screws, lock washers, and spacer spools. Attach
the controller to the bracket with cap screws, lock
washers, and spacer spools. On some designs, the
mounting bracket is attached to the actuator casing
rather than to the yoke.

Pressure Connections
To avoid personal injury or property
damage resulting from the sudden re-
lease of pressure, do not install any sys-
tem component where service condi-
tions could exceed the limits given in
this manual. Use pressure-relieving de-
vices as required by government or ac-
cepted industry codes and good engin-
nering practices.
Refer to figure 2–5 for pressure connection locations.
Supply, output, remote set point, external feedback,
and vent connections are 1/4-inch NPT, female. Pro-
cess pressure connections are 1/4- or 1/2-inch NPT
(optional). Use 1/4-inch or 3/8-inch pipe or tubing for
supply, output, remote set point, and external feed-
back connections.
Process Pressure Connection
The connection marked A on the bottom of the case is
the process input for all Bourdon tube controllers and
those capsular element controllers used in vacuum
pressure applications. The connection marked B is the
process input for capsular element controllers used in
positive pressure and compound pressure applica-
tions. See figure 2–5 for the location of the A and B
connections.
