Installation, Operation & Maintenance of the ZECV

Analog Pressure Controller

General Description

When applying Zcom diusers in an changeover/

bypass application with a constant volume rooftop

unit, provisions must be made to control duct static

pressure. The duct static pressure is typically

controlled by a system bypass damper installed o

of the supply duct, and controlled from a static

pressure tap installed 2/3 down the main duct.

Figure 2 illustrates a re commended installation of

the bypass damper to maximize mixing of the

bypass air with the return air. This location of the

bypass minimizes the opportunity for developing

hot or cold spots in the rooftop.

Installation Instructions

These instructions are intended only as a basic

guide for the installer. They do not assure

compliance with local codes. Consult the

authorities having jurisdic tion be

fore installing this

terminal.

Receiving Inspection

After unpacking the pressure controller, check it for

shipping damage. If any shipping damage is found,

report it immediately to the delivering carrier.

Supporting the Terminal

The basic control is light enough so that it can be

supported by the duct work in which it is installed.

Where the accessory modules such as coils,

attenuators or multiple outlets are included, the

assembly should be supported directly. Use the

support method prescribed for rectangular duct in

the job specications.

Duct Connections

Slip the inlet duct over the inlet collar.

The diameter of the inlet duct in inches must be

equal to the listed size if the terminal: e.g., a duct

that actually measures 8 in ches must be tted to a

size 8 terminal. Attach the

rectangular outlet duct

by using standard SMACNA slip and drive

connection method. Fasten and seal all

connections by the method prescribed by the job

specications.
