Screw Types and Usage:

M6 10mm Screws (shorter): Used for assembling columns to collapsing channels (4 per column, 16 total) and locking adjustable channels (8 per channel, 16 total).
M6 14mm Screws (longer): Used for assembling top supports to columns (4 per top support, 8 total) and connecting feet to columns (8 per foot, 16 total).
7/8" Wood Screws: Used for fastening the frame to the desk surface (14 total).
16mm Wood Screws: Used for securing the control unit to the desk surface (2 total).
Wood Screws (included with hand switch): Used for attaching the hand switch (2 total).

Weight Limit: The desk has a specified weight limit, and exceeding it can lead to error codes (E02).

Duty Cycle: The control box has a duty cycle. Continuous movement of columns for over 4 minutes can trigger an H01 error, requiring the desk to rest for 16 minutes. High room temperature can also affect heating elements and trigger this error.

Usage Features

Assembly Process:

Assemble Columns to Collapsing Channels: Use M6 10mm screws (shorter, 4 per column). Channels may need to be extended to expose screw holes. Ensure correct orientation of screw holes.
Assemble Top Supports to Columns: Use M6 14mm screws (longer, 4 per top support).
Fasten Frame and Control Box to Desk Surface: Use 7/8" wood screws for the frame (14 total) and 16mm wood screws for the control unit (2 total). Center the base on the desk surface, leaving 2" on the right and left sides. Pre-drilling is required for solid wood tops and optional for HPL tops.
Connect Feet to Columns: Use M6 14mm screws (longer, 8 per foot).
Lock Adjustable Channels: Use M6 10mm screws (shorter, 8 per channel). Ensure the control box and hand switch are placed so cables connect without tension.
Connect Power Cords: Connect the hand switch, four column power cords, and the main power cord to the control box. Use column cable extensions if needed.
Attach Hand Switch: Secure with two wood screws (included with the hand switch). Secure all cables with included cable ties. Flip the table over (with two people) and plug the power cable into an electrical outlet.

Important Assembly Note: Do not tighten machine screws fully until the end of each step to allow for proper centering.
