INTRODUCTION

General Description

The Guardian Jr. Airflow Monitor is designed to continuously monitor airflow through fume hoods. This permanently installed device provides both visual and audible alarms to alert the user of abnormal airflow conditions. A green light on the front of the monitor indicates normal flow conditions. When flow conditions lower than the set point are encountered, a red light is activated along with an audible alarm.

A test button is provided at the front of the monitor to allow the user to check the operation of the alarm.

Performance

The Guardian Jr. Airflow Monitor is designed for operation on all new non-explosion proof remote and integral style Protector Fume Hoods. It is also set up for operation for both the new Basic 47 and 70 inch style fume hoods. The monitor itself is available both as a field installed kit or a factory installed option.

INTRODUCTION

Component Identification

1. Air Inlet A portion of the air coming into the hood passes through the air inlet and across the flow sensors.

2. Normal Flow Indicator This green light indicates normal flow conditions.

3. Alarm Indicator This red light is activated approximately 6 seconds after the low flow set point is reached.

4. Test/Reset Button If no alarm is present, this button will cause the red lamp to light and the audible alarm to sound. If an alarm is present, the button will silence the audible alarm.

5. Adjustment for Alarm Set

Point

This potentiometer is used to set the low flow indicators for the alarm.

INSTALLATION

Disconnect your fume hood from its electrical service prior to beginning the installation of your new monitor.

The installation of your monitor is separated into two segments, the alarm module and the power supply assembly. Installation is as follows:

Alarm Module

1. Remove the right hand corner cover panel from your Protector Fume Hood. This is achieved by removing the service fixture knobs, if provided, and then removing the three Phillips head screws retained in the corner cover. Remove the black outlet cover plate located in the top electrical position on this panel.

a. If installing the alarm on either the Basic 47 or Basic 70 inch hood, you would need

to remove the right side access panel on the hood to gain access in removing the blank outlet cover plate.

2. Reinstate the corner cover panel to the hood using the screws that were removed in Step 1.

3. On the Protector Fume Hoods only, attach the molded rubber elbow connector directly to the back port connection on the alarm module assembly.

4. Thread the gray colored power supply lead wire assembly through the backside of the corner post and out through the electrical cutout in the corner cover. Attach directly to the connector located on the back of the power module assembly.

5. Insert the clear tubing (9 ft.) through the backside of the corner post and out through the electrical cutout in the corner cover. Attach the tubing directly to the elbow connector, cut to length, NO kinks, (Protector Hood) or the connector located on the back of the power module assembly.

6. Locate the alarm module in the electrical cutout in the corner cover or side panel of your hood, being careful not to pinch either the electrical wiring or sensor tube. Lock the bottom of the alarm module in place by sliding the bottom edge of the assembly down over the edge of the cutout. Next, secure the top of the alarm with the two #6-32 screws. Mounting holes for these screws are located underneath the black label surrounding the electrical cutout. Leave the label in place and secure directly through it to the corner cover.

7. Route the wiring and plastic tubing up the backside of the corner posts and attach as shown. Refer to Installation Drawings.

NOTE: Make sure to keep the tubing and wiring out of the travel area of the sash weights.

Power Supply Module

8. Locate the power supply module on the top of the fume hood liner assembly and use the supplied Velcro strips to secure in place.

9. Drill a 3/8" diameter hole in the hood exhaust collar or blower housing, depending upon your specific model of fume hood. Refer to Installation Drawings for exact locations.
