INTRODUCTION
General
In this manual, you will find information regarding:
•Venturi Valve Retrofit (VVR) specifications
•How to install the VVR with the PaceTM Critical Space Controller
(PACE), the Fume Hood Controller (FHC) and the Linear Module
(LMX)
•Detailed description of all options available for each setup and
controller
Product Overview
Antec Controls Retrofit are designed to replace obsolete controls
on currently installed Venturi Valves. The VVR is built to mount
directly onto the existing valves. Retrofits are designed to tether
into an existing potentiometer feedback airflow system or airflow
sensing system depending on application.
Safety Precautions
•Installation work and electrical wiring must be done by qualified
person(s) in accordance with all applicable codes and standards,
including fire-rated construction.
•When cutting or drilling into wall or ceiling, do not damage
electrical wiring and other hidden utilities.
•Use this unit only in the manner intended by the manufacturer.
If you have any questions, contact the manufacturer.
•Before servicing or cleaning unit, switch power off at service
panel and lock service panel to prevent power from being
switched on accidentally.
•Protect flammable materials nearby when brazing, Use flame
and heat protection barriers where needed. Always have a fire
extinguisher ready.
The manufacturer assumes no responsibility for personal injury or
property damage resulting from improper handling, installation,
service or operation of the product.
CAUTION
This mark indicates an important point for the proper
function of the Venturi Valve Retrofit. Improper setup
may cause unit failure. Pay close attention to all caution
points throughout this manual.

MOUNTING THE RETROFIT
Pre-Installation Checks
The following checks are required prior to installation:
•Visually inspect the valve for damage – If damage is found DO NOT INSTALL. Please
contact a Price representative.
•Visually inspect the Retrofit for damage – if damage is found DO NOT INSTALL.
Please contact Antec Field Support.
•Locate Calibration Data Tag with CFMs and VPOT points.
•Verify the potentiometer excitation voltage using a voltmeter, while the original
controller or equipment powers it. Measure the voltage across the red and black
wires.
Valve Preparation
The following steps should be performed for any VVR installation.
•Disconnect the three (3) potentiometer (POT) wires from the terminals on the control
board.
NOTE: Remove the control components from the base plate on the valve. Components may
vary depending on the control solution mounted on the valve but the valve should be left
with the control arm, POT and POT wires.
Calibration Data Tag
Control Arm
POT Cable
CAUTION
DO NOT cut the POT cable.
The system may still have airflow, to
reduce the chance of damage to the
existing valve, set the valve to the min
position before removing control
components.
