Mounting

Air Sample Connection

Initial-Position Relay

Select a mounting location which is free from vibration.

The SPC must be mounted with the diaphragm in any verti-

cal plane in order to obtain the lowest specified operating

set point. Avoid mounting with the sample line connections

in the “up” position. Surface mounting by the two 3/16“

diameter holes in the integral mounting bracket. The

mounting holes are 3 7/8” apart as shown in Figure 3.

The SPC is designed to accept a flexible tubing by means

of a barbed 1/4”slip-on connection. A 36” piece of ¼˝ ED

Flexible Tubing is included with the SPC as well as the

Pitot Tube for mounting in the plenum. Locate the sam-

pling probe a minimum of 2 feet down stream from the air

source. Install the sampling probe as close to the center of

the airstream as possible. Do not allow supply pressure to

blow directly into the Pitot Tube. Connect the provided

flexible tubing to the High-Pressure Inlet as shown in

Figure 2.

Each SPC includes a SPDT Relay that should be wired in

conjunction with the SPC and Power-Open/Power-Close

Damper as shown in Figure 1. This relay is included so

that when there is NO CALL for the FAN on the equipment

side of the Braeburn Zone Controller the bypass damper

will drive open. When a FAN call occurs the relay allows

SPC to operate normally.

The SPC is a static pressure switch designed to sense positive pressure in

the plenum for the purpose of controlling modulating bypass position.

The plated housing contains a diaphragm, a calibration spring and a snap-

acting SPDT switch. The barbed sample line connections located on each

side of the diaphragm accept flexible tubing. The enclosure cover guards

against accidental contact with the live switch terminal and set point adjust-

ing screws. The enclosure cover will accept a ½˝ conduit connection.

Pitot tube (air-probe) for mounting in plenum and 36 inches of flexible

¼ ˝ I.D. poly tubing is included with each SPC.

Initial Position Relay included to maintain open damper position during NO

FAN CALL (Not pictured).

Mount with the diaphragm in any

vertical plane.
