EASY SETUP GUIDE

WELCOME TO THE VENTA COMMUNITY!

Setting up your humidifier is much simpler than you would expect. Just follow these 7 steps and your humidifier will be up-and-running in less than 10 minutes!

1. UNPACKING

First things first, remove bottle(s) of Water Treatment Additive from the corner of your packaging (Only the AH550/AH555 models come with two sample sized bottles). Keep these handy as you'll need them in a bit. Unpack your humidifier setting the Styrofoam aside. You may want to return the Styrofoam to the box and keep the box for any future humidifier storage needs.

5. SET IT UP

Correct Placement

Incorrect Placement

Now it's time to set up the humidifier. Find the place where you'd like your humidifier to live, making sure to place it properly for best results! Humidifier should be placed in a location with a minimum clearance of 18-20 inches, including above. Set the humidifier there, but don't yet plug the unit in.

WATERLINE

Remove the upper housing from the lower housing and set it aside for a moment. Take the lower housing over to your sink/bathtub/water source and fill it with regular tap water up to the water line. Remember the bottle(s) of Water Treatment Additive? Go grab those and pour them into the water in the lower housing. Once it's filled, carry it back over to the upper housing.

Place the upper housing back onto the lower housing.

6. TURN IT ON

Plug the humidifier in, switch on device by briefly touching the power button in the display, set the power setting to the highest speed, and enjoy the fresh air! At the highest setting, the humidifier will need to run continuously for about 7–10 days to properly condition the room it is in. After that, you will notice the full impact of the humidifier upon the air in your home!

Only once the device is connected to the mains will the power button ⏻ glow to switch the device on and off.

7. ACTIVATE YOUR WARRANTY

Remember that serial number you wrote down earlier? Use that serial number to complete the registration card here in the manual to register your unit and activate your 2-year warranty!

HELPFUL HINTS

• Dishwashers: The Venta Humidifier's lower housing, disc stack(s), and upper housing (first removing the motor assembly from the upper housing) can go into a dishwasher on the cool or rinse cycle. It is recommended that it not be washed with dishes. The motor assembly cannot be submerged in water or placed in the dishwasher. DO NOT USE detergent, mild soap, bleach, or household cleaners.
• Cleaning of disc stack(s): If a dishwasher isn't an option, cleaning the disc stack(s) can be done by soaking disc stack(s) in hot water with Venta Cleaner or white vinegar for approx. 30 minutes. This will help loosen any buildup of calcium or lime that may have accrued. Always rinse with warm water after cleaning.
• Vinegar and Water Solution: Should be either 50:50 or 3:1 ratio of white vinegar and water used instead of Venta Cleaner.
• Do not use the appliance in an environment with temperatures consistently over 95 degrees Fahrenheit.

DEAR CUSTOMER,

With the Original Connect series, you have purchased a high-performance humidifier, which gives you even more convenient operation with the addition of a touch display and Venta AirConnect compatibility.

The Smart Life App allows you to operate your appliances remotely as well as to access information. The Original Connect supports healthy humidity and the natural reduction of pollutants in the air.

Here's how the Venta principle works

A fan directs the ambient air into the water-filled humidifier, where it flows through specially arrayed disk stacks. Hygienically clean air evaporates from their surfaces into the room. Simultaneously, the disks trap harmful substances such as dust or pollen, which are then washed off in the water and collected in the humidifier.

Over half of all Venta Humidifiers are sold on the basis of recommendation by satisfied customers. Our goal is that you are completely satisfied and that you recommend the Venta Humidifier to your family and friends. If you have any questions or concerns, please contact us at 888-333-8218 or [e-mail]

The use of WTA is recommended for the best performance and efficiency of your Venta Humidifier. Proper usage will prevent the formation of hard calcium deposits. Simply rinse and wipe out any sediment when changing the water. WTA serves three (3) purposes:

• It improves the performance of the humidifier by creating sheeting action on the disk(s) with the effect of increasing the amount surface area it covers.
• It helps remove calcium and lime buildup.
  • It kills bacteria and mold.

DIRECTIONS

Fill lower housing with water daily or as needed. Every 10-14 days add a dose of WTA. The lower housing should be periodically rinsed and cleaned every 10-14 days. One dose of WTA is 3.5 fl. oz. which is equal to one black marking on the left side of the label.

CAUTION!

KEEP OUT OF REACH OF CHILDREN

EMERGENCY FIRST AID TREATMENT: Contains Quaternary Ammonium Chlorides. Eye and skin irritant. In the event of contact with eyes flush thoroughly with water. In the event of skin contact, rinse with water. Harmful if swallowed. Do not induce vomiting. Seek medical attention. Venta WTA is recommended for use with the Venta Humidifier only. Shelf life when stored in a cool location away from sunlight: 30 months. After opening, use within 12 months. WTA is not suitable for ultrasonic, heat vaporizing, or atomizing-type vaporizer humidifiers. Not suitable for Venta models with Hygiene Disc.

... E2 is shown in the display?

The device has switched off automatically, because the motor is overstrained (e.g. through the intrusion of foreign objects or similar).

Measure: Remove upper housing. Check whether the disk stack in the lower housing as well as fan blades in the upper housing are freely movable. Next, place the device in operation.

... white spots appear in the background when you touch the display?

In dry rooms, electrostatic charging can cause white areas to appear in the background on the display. These do not affect the functioning or ability to control the appliance and do not constitute a defect.

... the power button ⏻ to switch on the device does not appear in the display?

Please check whether the power supply is connected to the mains.

... the power button ⏻ to switch on the device does not appear in the display, even though the power supply is plugged in?

be jammed between the upper and lower housings. Next, place the device back in operation.

FREQUENTLY ASKED QUESTIONS

HOW DOES THE VENTA DEVICE HUMIDIFY?

The Venta Humidifier operates by the process of cold evaporation, so you will not see any residue, vapors, or mists. The disc stack(s) rotate(s) in the water creating a very large evaporation surface area. When dry air meets the surface area of the disc stack(s), the water evaporates and is sent out into the room. By using the cold evaporation process, any excess humidity can be virtually ruled out.

WHAT LEVEL OF HUMIDITY CAN BE EXPECTED AND HOW OFTEN SHOULD THE LOWER HOUSING BE FILLED?

Under ideal conditions, a humidity level of 40–60 % can be expected. Some factors affecting humidity level are: heating/cooling, home insulation, layout of the home, air circulation, and the amount of water in the appliance. For severely dry areas or during the first days of use, you may notice the water evaporates more quickly and/or a lower humidity level will be reached. The water level of the lower housing should be checked and topped off daily.

WHEN IS THE BEST TIME TO RUN THE VENTA HUMIDIFIER?

Always! The Venta Humidifier is designed to be a year-round, 24/7 product. Because we wanted it to run year-round, we made the humidifier's power consumption as minimal as possible. For the best results, your humidifier should never be turned off or stored for long periods of time.

WHERE IS THE BEST PLACE FOR THE VENTA HUMIDIFIER?

If possible, the Venta Humidifier should be placed in the center of the room, or along a wall away from windows and a heat source. When using your Venta Humidifier for multiple rooms (larger model Venta Humidifiers) it should be placed centrally between rooms. Allow 18-20 inches above and on either side of the Venta Humidifier to allow air circulation.

WILL OPENING OUTSIDE DOORS AND WINDOWS AFFECT THE EFFICIENCY OF THE VENTA HUMIDIFIER?

The appliance works best in closed rooms to maintain a consistent level of humidity. Just as windows and doors are closed when air conditioning is running, doors between rooms may be left open to allow for air circulation.

IS IT NECESSARY TO USE THE VENTA WATER TREATMENT ADDITIVE?

The WTA helps prevent mineral deposits from becoming too difficult to remove so that any sediment can be rinsed out. In addition, the WTA helps improve the efficiency of the humidifier by allowing the water to sheet on the disk stack(s) instead of "beading" up, allowing maximum use of every square inch of the disk stack(s). The WTA also helps prevent odors and improves the performance of the Venta Humidifier. Not suitable for VENTA models with Hygiene Disc.

SHOULD MORE WATER TREATMENT ADDITIVE BE ADDED WHEN THE APPLIANCE HAS SWITCHED OFF AUTOMATICALLY AND THE WATER DISPLAY APPEARS?

No, because the ingredients of the WTA do not evaporate. Simply add fresh water to reactivate the WTA. One dose will help keep the humidifier from scaling up with mineral deposits up to 14 days.

WHAT HAPPENS WHEN THE VENTA HUMIDIFIER HAS NOT BEEN RUN FOR AN EXTENDED PERIOD OF TIME?

Simply give the appliance a general cleaning with the Venta Cleaner before using it again. Tip: Use of the Venta Cleaner is recommended before storing the appliance for an extended period of time to remove any mineral deposits that can harden over time. Or take advantage of Venta Air Technologies' Ultrasonic Cleaning service. Book online at https://www.venta-air.com/en_us/product/ultrasonic-cleaning/ or call us toll free at 888-333-8218 for pricing and details.

MY VENTA HUMIDIFIER APPEARS TO NOT BE HUMIDIFYING MY ROOM AS DESIRED

Our goal is to achieve 100% customer satisfaction. Initial product performance is largely based on the total coverage area including hallways, stairways, and other spaces that cannot be closed off, as well as the overall humidity level of the contents of the room. Dry furnishings (textiles, leather, wood, books, etc.) will require a longer period of time to absorb moisture until their humidity level is increased to a satisfactory level. Therefore, we highly recommend that you take this into consideration when evaluating the performance of your product. Dry rooms can take 7-10 days of continuous humidification to achieve an optimal humidity level. It's important that you are adding water to your unit regularly. In the event that you are dissatisfied with the performance of your product, please call us.

SERVICING YOUR HUMIDIFIER

CLEANING THE GEAR

DO NOT submerge the gear in water. To clean any buildup of calcium or lime from the gear "teeth," brush with a soft bristled brush. The gear teeth should be pointed toward the floor while brushing, otherwise deposits will fall into the gear and cause it to malfunction.

REMOVAL OF THE GEAR AND COUPLING

1. Switch the unit off.
2. Unplug the power cord from the outlet.
3. Remove the motor from the upper housing.
4. Remove the coupling from the gear by pushing the coupling down toward the fan and away from the gear

5. Pivot turn the gear 90 degrees, so that it is laying on its side.

6. Gently pull one of the two motor assembly arms approximately 1/8 of an inch away from the gear and remove the gear from the motor assembly.

7. Remove the locking ring from the center shaft of the fan by prying it up using a small screwdriver.

REPLACING THE GEAR AND COUPLING

A. Place the rubber coupling into the locking ring so the rubber feet from the coupling hang below the ring. When placing the coupling and ring on the center shaft of the fan, the rubber feet should line up with the notch marks on the fan. Snap the ring and coupling into place.
B. With the gear laying on its side, place it between the motor housing arms that suspend it above the fan.
C. While placing the palms of your hands against the motor assembly arms, apply slight pressure, and pivot the gear to the upright position. Check that the locking knob is properly seated in the support arm.
D. Insert the rubber coupling into the bottom of the gear and push it up into the gear until it fits tight. On models with a small white pin, first insert the pin through the rubber coupling and then push both up into the gear until it fits tight. Check that this is properly seated by spinning the fan with your hand. The teeth in the gear should slowly move in and out.
