Question 4

How to use the remote control of the VALBERG JBKOOL-21 fan?

Accepted Answer

The remote control of the VALBERG JBKOOL-21 tower fan works up to 5 meters away. Before the first use, you must remove the insulating tab from the battery compartment to activate it. The CR2032 3 V battery is included with the fan.

Using the remote control: Always point the top of the remote control towards the fan's screen to ensure good signal transmission. A beep confirms each button press, and the screen updates automatically.

Main buttons and functions:

Power: press to turn the fan on or to standby mode. The screen will display the active speed, ventilation mode, and oscillation.
Speed (+/-): increase or decrease the speed in normal ventilation mode (6 levels available), or select a preset program in Night or Natural modes.
Mode (M): toggle between the 3 ventilation modes (Normal ventilation with 6 speeds; Night ventilation with 2 programs simulating a gentle breeze that gradually decreases; Natural ventilation with 3 programs simulating an outdoor breeze).
Oscillation: activate or deactivate the automatic left-right movement. The corresponding indicator lights up on the screen when the function is active.
Timer: set an automatic start or stop. The duration can be set in 0.5-hour intervals (from 0.5 to 9.5 h) and then in 1-hour intervals (from 10 to 12 h).

Important information: The screen automatically turns off after about 1 minute of inactivity to save energy, but the fan continues to operate according to your settings. Press any button (except power) to turn it back on.

Battery replacement: If the battery is worn out, hold the remote control with the back facing up. Place your thumb (or a flat screwdriver) on the bottom of the remote to push and hold the small locking clip to the opposite side. Then pull the compartment groove to remove it by sliding it out. Install a new CR2032 3 V battery with the + side facing up, then close the compartment. Only use batteries of the same type or equivalent.

Question 6

The screws for securing the control box are not holding at step 6 - what should I do?

Accepted Answer

If the screw securing the control box (M) is not holding firmly at step 6 of assembling your VAL-SF40, here are the checks to perform.

First, make sure you have completely unscrewed the screw before inserting the box. The manual clearly states that you need to loosen the securing screw (M) by turning it counterclockwise with a screwdriver before inserting the control box (K) onto the inner tube (N). This step is crucial: if the screw is still partially engaged, the box will not slide properly onto the tube.

Next, check that the box fits properly into the guides of the inner tube. The box should align naturally with the tube without forcing it. If you encounter resistance during insertion, check that the inner tube is clean and that the box is not damaged. Any debris or slight deformation can prevent proper fitting.

For the final tightening, use a suitable Phillips screwdriver for the size of the slot of the screw (M). Turn slowly and steadily clockwise until you feel slight resistance. Do not force excessively: overtightening may damage the plastic thread of the box or tube, making it impossible for the screw to stay tight.

If the screw continues to not stay tight despite these checks, the problem is likely due to a defect in the thread. In this case, try slightly changing the position of the screw (a fraction of a turn) or check that the fixing hole of the box is not misaligned. If the problem persists, contact the ELECTRO DEPOT customer service with your proof of purchase, as it is possible that the box or tube has a manufacturing defect covered by the 2-year warranty.

Question 7

How to properly tighten the screws in step 5 when assembling the fan?

Accepted Answer

In step 5, the screws must indeed be tightened properly to ensure the stability of the fan. According to the VAL-SF40 manual, you use 4 screws (R) to secure the crossbars and tubes together.

To ensure the screws hold properly:

Check that the 4 grooves of the base and the crossbar align well before inserting the screws
Insert the screws gradually and tighten them firmly but without excessive force (risk of breaking the plastic)
Alternate tightening the screws two by two for even tension
Make sure all components are properly in place before tightening definitively

If the screws still do not hold, check that the grooves are not damaged or misaligned. Remember to unplug the fan before any assembly or disassembly.

Question 8

How and where to fill the water tank of the VALBERG JBKOOL-21 fan?

Accepted Answer

The water tank of the VALBERG JBKOOL-21 is filled by removing the removable tray located at the base of the fan.

Filling Steps:

Remove the water tray from its location at the base or back of the fan
Fill it with clean water up to the maximum limit indicated on the tank
Reinstall the tray by putting it back in place before turning on the fan

Usage Tips:

Use distilled water if possible, especially if your tap water is very hard, to avoid mineral buildup
Never let the water stagnate for more than a few days to prevent mold and odors
Empty and clean the tank every 2-3 days of use
To remove limescale, soak the tray in a vinegar-water solution, then rinse thoroughly before refilling

Important: The water tray must remain separate from the motor block and electronics of the fan - never immerse the main body of the fan in water.

Question 9

The water is no longer flowing in the VALBERG JBKOOL-21 fan: how to unblock and clean the system?

Accepted Answer

The water circulation problem usually comes from a blockage in the removable water tank (lime scale or deposits) or dirty air inlets/outlets. Here’s how to resolve it:

Cleaning the water tank

Unplug the fan
Remove the removable water tank and empty it completely
Rinse the tank several times with clear water to eliminate any deposits or residues
If lime scale persists, soak the tank for a few hours in water (with a little white vinegar if available), then rinse again
Dry the tank well before reinstalling it

Unblocking the system

Fill the tank with clean water only (tap water may contain lime scale)
Check that the air inlets and outlets are not blocked by dust - wipe them with a soft, damp cloth
Plug the fan back in and test

Preventive maintenance

To prevent the problem from recurring:

Empty the water tank every 2-3 days to avoid mold and deposits
Never leave stagnant water for more than a few days
Use clean water (ideally distilled water if you have very hard water)
Regularly wipe the surfaces and air inlets with a slightly damp soft cloth

Important: Never clean the device with solvents, aggressive chemicals, or sharp objects. Also, avoid submerging the fan in water.

Question 10

How to remove the L cap from the motor block to complete the assembly of the U-GO-Fresh?

Accepted Answer

The L cap is the plastic cover that attaches to the motor shaft. To remove it during assembly:

Locate the plastic cover on the motor shaft (at the center of the front grille)
Turn this cover clockwise until it completely detaches
Gently remove it

Once your assembly operations are complete, you can replace it by turning it in the same direction until fully tightened.

Important: Do not attempt to disassemble the motor block itself, which contains electrical components. Only the L cap can be removed.
