Question 1

Is it normal that the speed display is hidden when the timer is active?

Accepted Answer

Yes, this is a normal behavior of the U-GO-Fresh.

According to the manual, the fan's digital display shows different elements depending on the context:

During normal operation, the display shows the current speed (from 1 to 8)
When you program the timer (1-8 hours), the timer icon blinks and the display focuses on this setting
Once the timer is confirmed, the display turns off after a few seconds to save energy

How to restore the speed display:

Press any button (except the power button) to reactivate the display between your timer settings
Use the +/- buttons to adjust the speed - the display activates and shows the chosen level
Once the timer is finished and inactive, the display will show the operating speed again

This masking is intentional and allows the device to optimize energy consumption by alternating displays according to your activity.

Question 2

What is the noise level of the VALBERG VAL-SF40 fan in decibels?

Accepted Answer

The VALBERG VAL-SF40 fan has an acoustic power level of 51.86 dB(A).

To put this in perspective, this noise level is comparable to a normal conversation or a quiet office. It is relatively discreet operation for a standing fan, making it well-suited for use in a bedroom, living room, or office without being intrusive.

This noise level has been measured according to applicable standards and represents the maximum acoustic power of the fan during normal operation.

Question 3

What are the technical specifications of the power supply for the VALBERG VAL-SF40 fan?

Accepted Answer

Here are the precise specifications of the power supply for the VALBERG VAL-SF40 fan:

Voltage: 220-240 V~ (alternating current), 50 Hz
Rated power: 45 W
Measured power (maximum): 39.4 W
Cord length: 180 cm (1.80 m)
Protection class: Class II (double insulation)
Type of plug: Standard European wall plug

These specifications correspond to indoor domestic use. The power cord should be used in a dry atmosphere with adequate ventilation. If you need to replace the cord, mention the model VAL-SF40 and these characteristics to your spare parts supplier.

Question 4

How to replace the power cord of the VALBERG VAL-SF40 fan if it is damaged or lost?

Accepted Answer

The VALBERG VAL-SF40 fan does not have a removable external "power supply" like some devices. It is equipped with a fixed power cord of 180 cm in length that plugs directly into a standard European wall socket (220-240V, 50 Hz).

If your cord is damaged or lost:

You must replace the entire cord, not just a separate adapter or power plug
Contact the Electro Dépôt customer service (the official retailer) mentioning the reference VAL-SF40 to order an authentic replacement cord
You can also check www.electrodepot.fr/sav/notices where available spare parts and ordering procedures are listed
Avoid uncertified replacement cords: the VAL-SF40 is class II (double insulation) and requires a cable that meets safety standards

Specifications of the original cord: 180 cm, 220-240V 50 Hz, rated power 45 W. Keep this information to order the correct part.

Question 5

How to clean the blades of the VALBERG JBKOOL-21 fan?

Accepted Answer

Before any cleaning, always unplug the device from the power outlet.

Blade cleaning method

Use a soft cloth or a sponge slightly dampened with water (plain water or slightly soapy water)
Gently wipe the blades as well as the air inlets and outlets of the device
Completely dry after cleaning

Products and items to absolutely avoid

Never clean your JBKOOL-21 fan with:

Solvents, chemicals, or abrasive cleaning products
Gasoline, benzene, or alcohol
Metal brushes, scouring pads, or sharp objects
Complete or partial immersion in water

Tip: Regularly clean the air inlets to maintain good air circulation and ensure the optimal flow of 6.0 m³/min.

Question 6

Why does my VALBERG JBKOOL-21 fan turn off by itself after a few hours of operation?

Accepted Answer

If your VALBERG JBKOOL-21 fan turns off by itself after a day of operation, here are the likely causes:

Timer Activated

The fan has a programmable delayed automatic shut-off function ranging from 0.5 to 12 hours. This is the most common cause. Check the display on the control panel or remote control to see if the timer has been accidentally activated. Press the Timer button and use the +/- keys to set it to 0 or disable this function.

Power Outage

A power interruption or malfunction of the outlet can stop the device. Check that the outlet is working properly by plugging in another device.

Technical Issue

If the fan stops regularly without the timer activated, it may be an internal defect (motor or electronic circuit). In this case, contact the retailer for repair or exchange.

Tip: The manual does not mention automatic thermal protection. The JBKOOL-21 consumes 37.5 W and has an energy-saving feature (screen turns off after 1 min), but does not shut down due to overheating.
