Setup and Assembly
The FLEXISPOT EC5B desk frame is designed for straightforward assembly, typically taking less than an hour. While most steps do not require special tools, a drill may be needed for attaching your desktop (not included).
1. Unpacking and Component Check
Carefully unpack all components and lay them out on a clean, soft surface to prevent scratches. Verify that all parts listed in the packing list are present and undamaged. If any parts are missing or damaged, contact customer support immediately.
2. Assembling the Frame
Begin by attaching the lifting columns to the crossbar. Ensure all screws are tightened securely but do not overtighten. Next, attach the feet to the bottom of the lifting columns. The industrial-grade steel frame ensures stability and durability.

3. Attaching the Desktop
Place your chosen desktop (not included) upside down on a soft surface. Position the assembled desk frame onto the desktop, ensuring it is centered and aligned. The frame is adaptable for desktops measuring 120-180 cm in width and 60-80 cm in depth, with a thickness of 2 cm or more. Use appropriate screws to secure the desktop to the frame. Pre-drilling pilot holes may be necessary depending on your desktop material.

4. Connecting the Control Panel and Power
Connect the control panel cable to the designated port on the motor or control box. Ensure all electrical connections are secure. Finally, plug the power cord into a grounded electrical outlet. The desk is now ready for initial operation.
Operating Instructions
The FLEXISPOT EC5B features an intuitive control panel for easy height adjustment and memory functions.
1. Basic Height Adjustment
- Press and hold the Up (⌃) arrow button to raise the desk.
- Press and hold the Down (⌄) arrow button to lower the desk.
- Release the button when the desired height is reached. The desk moves at approximately 2.5 cm/second with low noise (under 50 dB).

2. Setting Memory Presets
The control panel allows you to save up to four preferred height settings.
- Adjust the desk to your desired height using the Up/Down buttons.
- Press the "M" button (or similar memory set button, if present). The display may flash.
- Immediately press one of the numbered preset buttons (1, 2, 3, or 4). The height is now saved to that button.
- To recall a saved height, simply press the corresponding numbered button. The desk will automatically move to the programmed position.
3. Anti-Collision System
The integrated anti-collision technology prevents the desk from lowering onto an object or colliding with an obstruction during upward movement. If an obstacle is detected, the desk frame will automatically stop and then move slightly in the opposite direction to clear the obstruction. This feature enhances user safety and protects your belongings.
