Usage and Maintenance

Quick Seven Step Installation

  • Clean humidifier inside and out – do not submerge the main engine compartment in water.
  • Clip the large 4-liter capacity water tank to the engine base.
  • Once in place add the lid to the top of the tank and fill with water
  • Fit hoses into place
  • Plug into mains
  • Turn on
  • Set timer and misting levels

How to Set Up the Timer

This humidifier comes with a built-in timer, which carries out two important functions.

The first is to set how often the misting interval should be and the second it to set how long the misting time per mist should be.

The first timer is the “CT” timer. This adjusts the mist time. You use this to set how often the misting should take place. You have a choice of six intervals with 0 being a permanent mist without any interruption and 1 being one misting per hour. If you choose to use an external controller, you must set the “CT” button to 0.

The second timer you are going to want to set up is the “WT” timer, which adjusts the length of each misting. It also offers six intervals to choose from. 1 indicates a misting duration of one minute, 2 is two minutes and so on, up to 120, which is for two hours.

How to Adjust Misting Levels

To adjust the misting level, you will want to push the “mist” button on the LED display and set it to the desired level. There are three misting levels:

  • Low – 100m/h
  • Medium – 200m/h
  • High – 300m/h

How to Put Humidifier into Sleep Mode

Push and hold the “Mist” button for approximately three seconds. This will turn off the LED display, while the humidifier continues to mist.

How Do I Install the Hose?

Ensure you keep the hose at a right angle. This prevents the risk of water backing up into the engine and causing the device to stop working.


Maintenance should be carried out once a month or if you notice the humidifier stops producing mist or starts leaking.

  • Get two brushes, one for the bucket and one for the gaps
  • Separate the pieces of the humidifier so you can clean each one individually
  • Clean the cover with a mild detergent and water, rinsing well
  • Locate the plug at the base of the tank and press to remove the device and clean
  • Clean the main engine chamber, but do not submerge in water. Use a brush to remove dust and dirt
  • Put the pieces back together again, refill and turn on
