Labconco Instruction Sheet 3909501, Rev. B, ECO F597 2 of 6
Installation Procedure
1. The enclosure comes prepared to except the Guardian™ 500 Airflow Monitor.
2. First remove the large 1.19" dia. gray hole plug. See Figure 2. See Figure 3 only to
reference internal assembly of the airflow monitor. Locate the elbow, locknut, and washer
and install it in the 1.19" dia. hole per Figure 2 and Figure 3. The enclosure baffle pivots
down to install the elbow, washer and locknut.
3. Cut the 1" hose supplied with the kit to 15.5" approximate length and install it between the
airflow sensor and the elbow.
4. Secure the Guardian 500 Airflow Monitor to the enclosure with double stick tape as
shown in Figure 4. The airway passage between the alarm module and the enclosure is
now complete.
5. Locate the metal hose cover and install with double stick tape per Figure 4. (Omit this step
on the Protector Work Stations.)
6. Locate the power supply transformer. One end should already be connected to the two-
pin connector labeled 15 VDC on the back of the alarm module and through the strain
relief bushing. If disconnected, then reconnect to power the airflow monitor. Plug the
115V power supply into a standard 115V duplex receptacle, the back of the accessory
FilterMate portable exhauster or the back of the accessory light. For 230V, plug into a
standard receptacle with your specific outlet plug. (It is recommended that the airflow
monitor be connected directly to the FilterMate switched auxiliary outlet so the
airflow monitor is powered at the same time.)
7. Installation is now complete.
