Frequently Asked Questions - Aqua Perfect HD5235 TEFAL

How do I fill the water tank?

Remove the top cover, turn the safety lock 1/4 up, lift the tank by the handle, unscrew the stopper, fill with cold water (min 0.5 gal, max 1.55 gal), tighten the stopper, reposition on base, and lock by turning the safety lock 1/4 down.

What does Auto Comfort mode do?

Auto Comfort mode automatically adjusts the target humidity based on room temperature. For example, at 20-21°C the target is 60% RH. The appliance stops when humidity is reached and restarts when lower. It measures temperature and humidity every 60 seconds.

How do I set a timer?

Press the TIMER button (D) repeatedly to set 1 to 12 hours. The display shows remaining time. The appliance will automatically shut off after the set time. You can increase the time by pressing again up to 12 hours.

What is the Warm Mist function and how does it work?

Press the WARM MIST button (E) to activate. After 10 minutes, the mist becomes warm. After 30 minutes, anti-bacterial action starts, removing up to 91% of E. coli and S. aureus. It also increases mist output by 20%. The red pictogram shows when active.

How do I clean the humidifier?

Unplug the appliance. Clean the tank with soapy water and rinse. Clean the vaporization area (around the piezo disc and heating element) using the provided brush. Do not immerse the base. Use the included descaler if scaling appears. Recommended weekly cleaning.

What should I do if the appliance does not turn on?

Check that the water tank is properly seated and locked. Ensure the humidity target is not already reached (select Continuous or lower target). Refill if empty. Wait at least 20 seconds for water to reach vaporization chamber. Check power supply.

Can I use essential oils or additives?

No, never put essential oils or other additives in the evaporation duct or water tank. Doing so may damage the appliance and void the warranty.

How does the Night mode work?

Press the NIGHT button (F) to turn off the water tank light and touch beeps. Note that the empty tank sound indicator will not work in night mode; only the red light will blink if water is low.

What is Continuous mode?

In Continuous mode (display shows 'Co'), the humidifier runs until 90% RH is reached or the tank empties. Mist is continuously emitted and you can adjust mist volume. It restarts when humidity drops below 80%. Note that very high humidity may be unhealthy; optimal is 50-60%.

What if the mist stops suddenly?

Check if the timer has expired (turn on again). Check water level (refill if blinking). If the target humidity is reached, the appliance will stop temporarily. Also ensure the nozzle is not blocked and the appliance is on a flat surface.

USER MANUAL Aqua Perfect HD5235 TEFAL

Depending on model HD523x only

EN - PLEASE READ THIS INSTRUCTION MANUAL CAREFULLY AS WELL AS THE INSTRUCTIONS ON SAFETY AND CLEANING BEFORE YOU START USING THE APPLIANCE. PLEASE KEEP THIS INSTRUCTION MANUAL. FOR YOUR SAFETY THIS APPLIANCE IS COMPLIANT WITH APPLICABLE STANDARDS AND REGULATIONS (LOW VOLTAGE AND ELECTROMAGNETIC COMPATIBILITY DIRECTIVES...).

Air that is too dry can cause or aggravate sinus and respiratory problems, lead to dry skin, nose and throat and dry out plants and furniture.

Your humidifier is an effective device for diffusing water vapor in the surrounding air.

Humidity, which is expressed as Relative Humidity (RH), is the quantity of vapor present in the air expressed as a percentage of the maximum quantity of vapor that the air can hold at the same temperature without causing condensation.

Relative Humidity is measured with a hygrometer.

OPERATING PRINCIPLE

Your humidifier uses two complementary humidifying systems:

• A cold vapor system: a piezo disc that vibrates at an ultrasonic frequency to create tiny water droplets.
• Heated mist system for anti-bacterial and turbo effects.

It can thus be used to automatically increase the level of humidity of the surrounding air and it also has an electronic hygrometer for precise control of the Relative Humidity.

LOCATION

The use of a humidifier is particularly recommended in winter but the house should still be regularly aired.

First, place the humidifier in the room requiring priority treatment. It is suitable for a room up to 577 sq ft. (53,6m2).

Press button (A) to start the appliance or to put it on standby. The digital screen lights up and the device starts directly in AUTO mode.

Selection of operating modes using button B. Select one of the three modes by repeatedly pressing the button B.

1 - AUTO COMFORT MODE:

The appliance will automatically adapt the humidity level according to the room temperature for optimal comfort at home.

In order to reach the optimal comfort in the room you are in, this setting takes in account the room temperature and calculates the optimal humidity level.

When the humidity in the room is lower than the program, the appliance operates at maximum speed.

When the humidity in the room is reached, the appliance stops working and re-starts at maximum speed as soon as the humidity in the room is lower than the program.

The humidity and the temperature in the room are measured every 60 seconds.

Temperature	≤19 °C	20-21°C	22-23°C	24-25°C	26-27°C	28-29°C	30-32°C	33-36°C	≥37°C
Humidity target % RH	65 %	60 % 55 %	50 % 45 %	40 % 35 %	30 % 25 %

You can select the warm mist function with Auto comfort mode.

2 - CONTROL MODE:

- Humidity level: Button B for adjusting the required (target) humidity level;

Select the required humidity level by pressing button B several times.

The humidity level displayed is the required level that you have set (between 45% and 90% RH).

You can select the warm mist function with Control mode.

- Mist volume: Button C

Select the required mist volume by pressing button C several times. There are three speeds available.

You can adjust the mist volume in order to reach faster the required level of humidity.

PLEASE NOTE: This setting cannot be used for AUTO COMFORT mode.

3 - CONTINUOUS MODE:

Press the Button B, until the continuous mode, "Co" appears on the digital screen.

The appliance operates until reaching 90% RH (safety limit) or until the reservoir is empty. The mist is permanently emitted and you can adjust the mist volume.

The appliance will stop working automatically when the humidity level of the room is over 90% RH and it will re-start when the humidity level of the room measured is 80% RH.

WARNING: In the continuous operating mode, the humidity in the room can reach very high levels that are not beneficial to health and can damage certain objects. The recommended optimal humidity level is between 50 and 60% RH.

- Mist volume: Button C

Select the required mist volume by pressing button C several times. There are three speeds available.

- Cleaning the vaporization compartment (around the piezo disc 13), the heating element and the piezo disc.

Rinse regularly (every 3 days) the water base with fresh water and dry it with soft dry rag.

IMPORTANT: make sure that no water gets into the fan air outlet (16).

Regular cleaning of the piezo disc and heating element will avoid scaling. Do not use hard or abrasive utensils, only use the brush provided with the device.

In case of scaling appearance, please refer to the paragraph "CLEANER AND DESCALER PROVIDED WITH THE APPLIANCE".

WARNING : we recommend to give the heating element and the piezo disc a complete clean as soon as scaling sediment appeared on them to preserve same level of performances.
