3. See Figure 2 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 1 and Figure 2 The enclosure baffle pivots down to install the elbow washer and locknut 3 Cut the 1 hose supplied with the kit to 10 5 approximate length and install it between the airflow sensor and the elbow 4 Secure the Guardian Digital alarm to the enclosure with double stick tape as shown in Figure 3 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 3 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 Labconco Instruction Sheet 3909400 Rev F ECO F288 1 of 7 Remove Large 1 19 Dia Hole Plug
