MDFD -6 - Six heads Ultrasonic dry fog humidifier system

Installation

  • WARNING - Do not install the Fog Generator in the same room or zone that is being fogged.
  • WARNING - Always make sure the water is at the optimal level in the water tank and the torch before powering the EBU.
  1. Install the fog generator on a flat surface, making sure it is level.
  2. Remove all 6 front covers
  3. Lift and remove the fog collector hose adapter
  4. Remove the water container, cover without damaging the water sensor rod.
  5. Use a ½” hose (12.70 mm) and hose clip to connect the water supply to the water intake located on the side of the unit. We recommend, on the main water supply line, the installation of an on/off valve, to be able to shut off the water supply during maintenance, repair or storage. Make sure, upon the water hose installation that the water valve, in the interior of the water tank did not rotate and it maintained the horizontal position.
  6. Open the water supply valve. Wait until the water stops filling the water tank.
  7. Check the water level on all 6 torches. Water level in all torches should be ¼” (6 mm) higher than the window middle line. If water level is not equal in the all torches, that means the fog generator is not leveled. If water is not filling up one or more torches, evacuate the air from the system by gently squeezing the white water supply hose.
  8. Close the water tank cover.
  9. Connect the female connector of the power supply cable to the flange connector on the base of the fogger. Waterproof the connection by rotating the lock plastic ring attacked to the power supply cable connector.
  10. Connect the male connector of the power supply cable to the flange connector on the power supply unit. Waterproof the connection by rotating the lock plastic ring attacked to the power supply cable connector.
  11. Plug the power cable from the power supply to a power source. Switch ON the switch located on the power supply unit. When the power is connected the red led light on the power supply unit and on the fogger base will be on and all 6 fans will start working.
  12. Connect the water level sensor white connector, coming from the top plate of the fogger, to the connector on the water container cover. The unit will start generating dry fog.
  13. Install the fog collector hose adaptor.
  14. Install all 6 front covers on the fogger.
  15. We recommend the use of an extension fog hose (not included) 6” (152mm) diameter and 6 feet (1.80m) longer depending on each client custom installation. Connect the fog hose extension to the fog collector hose adaptor, installing it vertically or with a downward inclination to avoid water accumulation in the hose.
  • WARNINGS
  • Always install the power supply as far away as possible from the fog generator.
  • Do not operate the fog generator when the temperature is below the freezing point.
  • In case of using a reverse osmosis water filtration system, it must be kept a minimum of 15ppm (15 parts per million) of dissolved salts in the water for the automatic safety shut-off water sensor to be operational, otherwise the fog generator will not start.
  • If you attach a supplementary hose to the existing one, it must be positioned vertically or with a downward inclination to avoid water accumulation.
  • The fog generator is equipped with an automatic safety shutoff water sensor. It will immediately turn off the unit if the water level is too low, preventing it from being damaged. It will instantly start up again when water is added. The fog generator will not work if the sensor is unplugged.
  • The power supply is equipped with an alarm warning system (audio signal) when a defective EBU(s) is detected in the system .
