Remove all components from packaging. 2. Select an area to mount the control box. Note: The control box should be mounted to a vertical wall. We recommend mounting the control box at a height of 6 ft. (1.8 m) or less. The chemical suction line must reach the bottom of the chemical container. The bottom of the chemical container should not be positioned higher than the bottom of the control box. 3. Attach the control box mounting feet to the back of the control box, using the four screws provided in the parts package. 4. Mount the control box to the wall using the four screws and plastic anchors provided in the parts package. Note: To drill holes for the plastic anchors, use a 5/16 inch drill bit. 5. Install the air purge valve (QFSOV38) and tee fitting (QFT38) as shown in the diagram. AIR PURGE SYSTEM DIAGRAM SOLUTION OUT AIR OUT 8. Run tubing (H38CP) from the air outlet (QF1238) on the control box to the air inlet fitting on a nozzle assembly. Then run tubing from the air outlet fitting on the original nozzle to the air inlet fitting on the next nozzle. Repeat as needed for multiple nozzles. Note: The air and solution lines must be routed to the appropriate fittings (as labeled), or the mist quality of the unit will be negatively impacted. Make sure to insert the tubing all the way into the fittings to ensure proper connection. 9. When you reach the last nozzle, either plug the air and solution outlet fittings, or loop the air and solution lines from the last nozzle back into the system. Note: Depending on your configuration, plugs (QFP38), additional tee fittings (QFT38) and/or additional tubing (H38CP) may be required to complete the installation. 10. With the air inlet valve (HV60-H) in the closed position, connect a compressed air line to the air inlet fitting (SSE12). The air inlet fitting is 1/2 in. FPT. 11. Set the timer (TR120MF) for the desired delay time and run time, as described in the timer adjustment instructions on page 9. 12. With the power switch (TS2, TS2PLATE, TSBT12) in the OFF position, plug the unit into a GFCI protected 120 VAC power outlet. AIR PURGE 13. Follow all instructions from chemical manufacturer. Place the chemical suction line into a container of pre-mixed chemical solution. QFSOV38 TO NOZZLES QFT38 6. Mount the mist nozzle assembly (FG-NA-N130, FG-NA26SS) in the desired location, using the included screws and plastic anchors. Repeat as needed for multiple nozzles. 7. Run tubing (H38CP) from the tee fitting (QFT38) to the solution inlet fitting on a nozzle assembly. Then run tubing from the solution outlet fitting on the original nozzle to the solution inlet fitting on the next nozzle. Repeat as needed for multiple nozzles. Model No.: MU-6, FG-NA-N130, FG-NA-26SS, AND RELATED ITEMS Page 4 of 8 | 20220725 User Manual: Wall-Mounted Mist System | English READ ALL INSTRUCTIONS BEFORE OPERATING EQUIPMENT Operation Instructions Misting with chemical products can be hazardous. Know the hazards of your chemical products prior to use. Wear appropriate personal protective equipment and follow all instructions and safety precautions in accordance with the SDS for your chemical product. 1. Prepare the area to be misted. 2. Verify the delay time and run time settings on the timer (see Timer Adjustment Instructions) 3. Make sure the air inlet valve (HV60-H) is open, and the air purge valve (QFSOV38) is closed. 4. Turn the power switch (TS2, TS2PLATE, TSBT12) to the ON position. 5. To activate the unit, push the green button (BUT78GR). The unit will begin cycling through the delay and run time intervals set on the timer, beginning with the delay time. 6. At the end of the run time, the unit will shut off. Observe appropriate safety precautions when reentering the area, in accordance with the SDS for your chemical product. 7. Turn the power switch (TS2, TS2PLATE, TSBT12) OFF to prevent unwanted activation of the unit 8. With the air inlet valve (HV60-H) in the open position, open the air purge valve (QFSOV38) to clear any solution from the lines. Close the air purge valve (QFSOV38) after all solution has been cleared from the system. Troubleshooting Instructions • If air passes through the pump (P56/P56K/P56V) without cycling, the pump needs to be replaced. • Check the chemical suction line and strainer for debris or damage. Clean or replace as needed. To prevent damage to the unit, the strainer (STR14) must always be used. Maintenance Instructions To keep your mist unit operating properly, periodically perform the following maintenance procedures: Note: Before performing any maintenance, disconnect the unit from the electrical power source and compressed air supply, and open the air purge valve (QFSOV38) to release any air pressure stored in the system. • Inspect the pump (P56/P56K/P56V) for wear and leaks. • Inspect all hoses for leaks or excessive wear. Make sure all hose clamps and push-fittings are in good condition and properly secured. • Check the chemical suction line and strainer for debris and clean as needed. • Drain your air compressor tank on a regular basis to help extend pump life. An air source with a high moisture content will accelerate pump wear. Note: If your air source has a high moisture content, you may wish to install a water separator (WS-20CFM) before the unit.

The four switches in the top left (Function) control the timer mode. For fogging/misting applications, switches A, C, and D should be ON, and switch B should be OFF. This puts the timer in Dual Mode. 2. The six switches in the bottom left (Time Base) control the time interval. The timer is factory set to MINUTES. To change the Time Base to seconds or hours, refer to the chart below. 3. The five switches in the top right (Dual Mode t1) control the delay time. 4. The five switches in the the bottom right (Dual Mode t2) control the run time. The active time for each function is equal to the combined values of any switch(es) that are ON. NOTICE: the timer is factory set at 2 minute delay, 8 minute run time. FOAMit PN:TR120MF Timer Setting Example 2. TIME BASE (E to K): Switches E, F, and G control t1. Switches H, J, and K control t2.
