MDFD - 1 - One head 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. Use the 2 installation holes on the wall plate to install the fog generator, making sure is leveled.
  2. Use a ½” hose (12.70 mm) and hose clip to connect the water supply to the water intake located on the right 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 floater, in the interior of the water tank did not rotate and it maintained the horizontal position.
  3. Open the water supply valve. Wait until water stops filling the water tank.
  4. Check the water level in the torch . The water level in the torch should be ¼” (6 mm) higher than the window middle line.
  5. Attach the fog hose to the fog exhaust outlet using the 45º adaptor.
  6. Connect the EBU connector cable to the wall plate white cable connector on the left side of the unit. Waterproof the connection by rotating the lock plastic ring attacked to the connector.
  7. Connect the power supply connector to the power connector located on the left side of the wall plate. Plug the power cable, of the power supply, to a power source. When the power is connected the green led light on the power supply will be on and the fan will start working.
  8. Connect the water level sensor white connector, coming from the wall plate with the connector on the water tank cover. The unit will start generating dry fog.
  9. Install the front cover of the fog generator.
  • WARNING
  • 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.

  • No fog , but the fan is working:
  1. Verify if the water sensor connected. The white water sensor connector, coming from the wall plate, has to be connected to the water tank cover.
  2. Verify if the water tank is closed. The water sensor rod must be in contact with water.
  3. Verify if the EBU’s electrical connection is correctly attached. Power off the system and plug and unplug the connector and restore the power.
  4. Is the EBU dirty? Use the EBU cleaning procedures.
  5. If after the verifications described on the steps 1 to 4, the fogger is not functioning, it means that the EBU is defective. Contact the Theotek Groupe Inc. customer service, for the EBU repair or replacement, at (514)892-0246 or by email at info@theotekgroup.com.
  • No fog and the fan don't work:
