Installation

Step 3: Locate the Hood Probe

Due to the wide variety of fume hoods and configurations available,

there is no single hood probe location that will work for all fume

hoods. Contact the fume hood manufacturer to obtain the

optimum side wall probe location for the specific model hood

being used.

If no information is available, generally good performance is

achieved when the probe is mounted as shown in Figure 2.

Step 4: Install the Hood Probe

Before proceeding, reference the fume hood manufacturer

recommendations for best method and safety precautions for drilling

the fume hood sidewall.

a. Drill a 7/16" diameter hole in the side wall of the fume hood in

the location selected in Step 3.

b. Working from the inside of the fume hood, insert the end of the

tubing through the drilled hole feeding the entire length through

up to the probe.

Step 5: Wiring the Terminal Strip

On the back of the ABVA there is a 5-conductor (screw-less) terminal strip used for connecting the

"Remote Mute Input" and "Alarm Relay Output". If these features are not being used, proceed to Step 6.

Otherwise, route the wires through the appropriate holes or electrical box knock-outs and connect to the

respective terminals. Note: Connections to the terminal strip are made by pushing the button above the

terminal, inserting the stripped end (1/4") of the wire into the hole and releasing the button.

Step 6: Connecting Input Power

Route the cord end of the DC Power Module through the appropriate hole or electrical box knock-out and

insert into the power plug located on the back of the ABVA.

Step 7: Connect the Tubing to the ABVA

Route the hood probe tubing through the appropriate hole or electrical box knock-out, using caution not to

cause any kinks. Slide the tubing over the sensor port on the back side of the ABVA.

Step 8: Secure the ABVA

Secure the ABVA to the mounting surface using the appropriate two screws provided.

c. Firmly insert the probe into the predrilled hole. It

should not be required; however you may apply some

sealant / adhesive to the back of the probe flange to

secure the probe to the sidewall if desired.
