---|---
2. Remove everything from the cabinet. Turn the cabinet over and insert the casters snugly into the bottom. Just use your hands! Using tools can crack the cabinet. 3. Turn the cabinet upright and place the wide end of the float in the circular area in the bottom of the cabinet. Slide the float support down to the bottom and position the screw tabs over the holes in the cabinet base. Use a Phillips screwdriver to screw in the float support. Do not overtighten or use a drill. 4. Locate the vent on the back of your Executive. It has a narrow lip along the top. Your wick is labeled TOP and BACK. With the back of your wick facing the vent, and the top facing up, slide the wick down onto the vent lip until it catches. 5. Install your 1051 air filter by clipping the filter’s hooks into the slots on the back of your Executive. About water additives:
• Do not use essential oils in your Executive.
• Do not use water softeners.
• We recommend our Essick Air Bacteriostat to help inhibit mold growth.

6. Put your Executive in the most centrallylocated room of your home. It should be on a level surface against an interior wall. Make sure it’s at least two inches from the wall so the humidistat (on the cord) can accurately read your humidity. More about positioning:
   • To maximize humidity circulation, put your unit near a cold air return.
   • If you prefer to put your unit in the room where humidity is most needed, you can! But the humidity won’t circulate as well with this method.
   • Don’t put your humidifier under a window, as condensation may occur.
   • Put the unit on the bottom floor of a multi-story home.

7. Put the fan assembly on the cabinet.
   Make sure the float makes a solid connection with the fan switch inside the fan assembly. The fan switch looks like a small, silver diving board.

8. Fill your water bottles, then tighten the caps with your hands, making sure the caps are correctly threaded. Do not overfill the bottles. Your Executive holds 5.7 gallons of water. Note: Each bottle holds 2.75 gallons per bottle. The right bottle will empty first, putting .2 gallons of water into the cabinet. At that time, you can refill the right bottle to get the full 5.7-gallon capacity and maximum run time.

9. Lift the bottle end covers on each side of the fan assembly, and place the bottles in your Executive with the caps facing down.

10. Wait 20 minutes for the wick to become fully saturated, then proceed to step 11.

11. Plug in your unit and press the power button power-off .

12. Set your fan speed by pressing the large or small fan buttons to increase or decrease fan speed. Your Executive has nine fan speeds that are displayed by F1 (the lowest) through F9 (the highest). Note: On higher speeds, the Executive puts out a tremendous amount of humidity, so it’s louder on these levels. Most of our customers liken it to the sound of a box fan. Rest assured there is nothing wrong with your unit, it’s just working very hard to put out much-needed humidity.

13. Set your humidity level from 25% to 65%.
    Press the large or small water drop buttons to increase or decrease the humidity setting. The humidistat on your cord will read your home’s humidity and turn your fan off when the set humidity level is reached. When set to 65%, your unit will run continuously.

14. Press the crescent moon button to turn off the panel lights while you sleep (all of your settings will remain set). Press any button to turn the lights back on.

That’s it! Your Executive is ready to use.

ABOUT THE CODES

F – The F code means your unit is empty and needs to be FILLED with water.
CL – Your CONTROLS ARE LOCKED on the current setting. Activate the control lock by holding the power button for five seconds, until CL appears. Your Executive will lock on the current fan and humidity settings. Release the lock by pressing the power button again for five seconds until the display flashes CL three times, letting you know the lock is off.
CF – The CF code triggers after 720 hours of use and means it’s time to CHECK YOUR FILTER (wick). Unplug your unit and check your wick. If your wick is still in good shape, simply clear the code by plugging your humidifier back in. If your wick needs replacing, install a new 1041 Super Wick®.

HOW TO CLEAN YOUR EXECUTIVE

Regular cleaning is important for preventing mold, mildew, and other bacterial growth in your humidifier. It also keeps your Executive working its best.

1. Let the unit run until it’s empty, then turn it off and unplug it.
2. Remove the fan assembly, bottles, and the wick. Throw your wick away if it is time to replace it. Otherwise, put it in a sink while you finish cleaning your Executive.
3. Pour out any remaining water from the cabinet and water tanks.
4. Fill the cabinet half-full with water and add 1 cup of white vinegar. Let sit for 20 minutes. To disinfect, replace the vinegar with 1 teaspoon of bleach. Do not mix vinegar and bleach.
5. Fill the water bottles half-full with water and add 1 cup of white vinegar to each. Put the caps back on, shake the bottles gently, then let sit for 20 minutes. To disinfect, replace the vinegar with 1 teaspoon of bleach in each bottle.
6. After 20 minutes, empty the cabinet and bottles.
7. Dampen a sponge with white vinegar, wipe down the cabinet interior and bottles, then rinse everything thoroughly. To disinfect, replace the vinegar with bleach. Wipe down the bottles and cabinet interior only.
8. Wipe everything dry and replace the wick, if needed.
   Then reassemble.

When storing your Executive, discard the used wick and disinfect the unit using the directions above. Dry the unit thoroughly, and store in a temperature-regulated area. Do not install a new wick until you are ready to use your humidifier again.
