2. USAGE
This height adjustable desk has an electric motor and is designed for use in dry work areas only.
The desk height is adjustable so that it can be positioned at the most ergonomically suitable height. These
desks are designed only for the purposes included in this manual. They should not be used
in environments with high humidity or dampness. Any other use is at user’s risk.
Do not move around, crawl or lie under the desk frame. Do not sit or stand on the desk frame.

Liability: Under no circumstances does the manufacturer accept warranty claims or liability claims
for damages caused from improper use or handling of the desk frame other than that which

3. SETUP AND INSTALLATION
Once the desk has been assembled, adjust the feet so that the desk is level and does not shift its position.
After this, connect the desk to the 110v or 230v outlet and the desk is ready for use.
Check that no cables can get jammed.
Choose a placement for the desk that’s a safe distance from window frames, radiators, furniture etc. so
that people do not get stuck or trapped by the desk.
Do not place any objects that are taller than 20” underneath the desk.
After it has been assembled, when moving the desk, DO NOT lift the desk by the desktop. Lifting
tis way can stress the fasteners connecting the desk base to the desktop. Lower the desk completely and
lift the desk by grabbing the top of the desk base or by removing the desktop first.

I. Carefully place the upside down desk base on the under underside of your desktop. Place the
base where you want it. Some will want the frame to be all the way to the edge of the desk. We
recommend leaving at least 1/2” of desktop width (on each side) protruding beyond the frame width.
Then slide the Center Rails to ensure the tape mark (step D) is centered between the Top Mount
Frame Ends.
•Your desktop may or may not be pre-drilled. Please check both sides of the desktop before placing
the desk base on it for pre-drilling! Carefully place the upside down desk base on the underside of
the desktop.
•Adjust the width of the base to fit the desktop by sliding the two halves outward (47.2” to 70 . 9 ”
max).
Note: minimum top size: 47.2” wide x 24” deep
Now, proceed with securing the desk base to the desktop using qty 6 of the larger Pan Head
Screws.(Part#15)
Install as follows:
3 per side bracket (left)

J. IN THIS FOLLOWING STEP, DO NOT OVERTIGHTEN SCREWS. OVER TIGHTENING MAY
CAUSE THE PLASTIC ON THE COMPONENTS TO BREAK.
Use qty 2 of the smaller Pan Head Screws(Part#16)
to attach the Control Box (Part #5) on one desk,
THEN REPEAT THE SAME PROCEDURE ON
THE OTHER DESK. Ensure enough clearance
at the wire ports for cable connections.
K. IN THIS FOLLOWING STEP, DO NOT OVERTIGHTEN SCREWS. OVER TIGHTENING MAY
CAUSE THE PLASTIC ON THE COMPONENTS TO BREAK.
Place the Keypad (Part #6) so the front of the keypad runs flush
with the desktop edge (or recessed up to 1/8”). The Keypad can
be placed anywhere along the front edge of the desk, but we
recommend placing it near the side so it doesn’t interfere with
your chair or legs when seated.
Use qty 2 of the smaller Pan Head Screws (Part#15) to attach
