Instructions

Installation instructions for the Venturi Air Valves are

presented for various actuator types. These

instructions consist of the following:

 Section 1 — mounting the valve.

 Section 2 — adjusting AVC airflow.



Section 3 — actuation and sensors.

Section 1: Mounting

1. Move the valve to the installation area. Remove

the valve from the shipping package. Do not

carry the valve by the flow sensor, valve

extension rod or any controls. See Table 1 for

single-body and Table 3 for multi-body valve

measurements.

NOTE: Take care not to break or bend the

airflow sensor taps during installation.

2. Verify the correct airflow direction and orientation

of the valve in the ductwork (for example,

Horizontal).

NOTE: Before installing the valve, hold in the

intended position and push on the cone inside

the valve to ensure that it moves freely.

NOTE: Valves that are not mounted in a true

horizontal or vertical position as determined by a

level may have performance issues. If a controls

enclosure is attached to the valve, the controls

enclosure must be mounted vertically.

3. Support the ductwork within 12 inches of the

valve.

NOTE: For single bodied air valves, do not crimp

or otherwise deform the ends of round air valves.

4. Connect the ductwork to the valve’s inlet collar

using drawband, bolting or other accepted trade

practice.

Drawband connection for ductwork and valve.

5. Connect the ductwork to the valve’s outlet collar

using drawband, bolting or other accepted trade

practice.

6. Seal all ductwork and check that the duct

connections are airtight.
