Description of the DESKLINE®Desk Frame 2
The Desk Frame 2 (DF2) is, as the name indicates, a complete frame from LINAK®. It is characterized by a rethought frame concept,
evolved around a new top frame called the Beam.The Beam contains all electronics including the motor and all cable wiring.The
DF2 is very fast and intuitive to assemble as the few parts are carefully designed to be either clicked together or attached with
only a few screws.
The DF2 has a clean design. The lifting columns have no visible gliding pads and no punch holes in the profiles, and the internal
wiring and pre-installed motor in the beam ensure that only the mains and the desk panel cables are visible. The DF2 is of the
well-known LINAK quality and performance similar to other 3-part columns. As standard, the DF2 features the new anti-collision
technology, Desk Sensor™ 1, ensuring that collisions with obstacles do not damage the furniture. The DF2 reuses the existing
DESKLIFT™ Feet for mounting the lifting columns either on top of or recessed in the foot construction.
The method of packing ensures optimized logistics.All main components are packed individually and the quantity is aligned.
Figure 1 Names of the DF2 parts
The DF2 can be delivered with a mounting kit consisting of:
• 22 mounting screws for the beam and the cables (4.5 x 20 mm)
• 2 mounting screws for the desk panel (4.0 x 35 mm)
• 3 cable clamps (Ø6.6 mm)

Page 12 of 24
Disassembly tool
Ordering code: SA1023W1241.
The DF2 is available as a set-packed solution.
For the set-packed solution the main components of a DF2 frame are packed in separate boxes meaning that a DF2 frame
consists of 4 boxes:
• The beam (1 piece)
• The lifting columns (2 pieces)
• The cantilevers (2 pieces), the selected DPG, mains cable and optionally a mounting kit containing screws for mounting
the tabletop and the DPG as well as cable relief clamps
• The feet (2 pieces including the screws for mounting and the adjustment screws for the foot)
The set-packed solution simplifies logistics at the OEM end, making it easy to select the right components for the desk and
ensuring that all parts are included.
A bulk-packed solution is typically an advantage for high volume OEMs who assemble the frames or the complete desks at
their factories.

Mounting guidelines for the Desk Frame 2
Recommended tabletop:
Material Veneered chipboard
Plywood
Thickness Min. 21 mm (13/16”)
Size Min. 700 x 1200 mm (27” x 47”)
Max. 1000 x 1830 mm (39” x 72”)
Table size and type
The DF2 is designed for T-desks and must be mounted centrally on the tabletop.
DF2 mounted centrally on the tabletop
Important:
The DF2 has a great feature which prevents overheating of the system. The temperature of the motor and the
electronics is calculated by the SW during use and it depends on load, run time, etc. The DF2 duty cycle is 5 % ≈ 1
minute continuous use at full load, followed by 19 minutes pause. If the DF2 is being used beyond the duty cycle, the
system gets hot and stops, and the DPG will show error code E90. After a few minutes break, the DF2 will be able to
run for another stroke. However, to cool down the system to factory settings, the DF2 must cool for at least 2 hours
with the mains plugged in.
Please note:
If you disconnect mains, the DF2 SW cannot work and thus not calculate the temperature. When the system is powered
on again, the SW will continue to calculate using the data from when the mains was disconnected.

Page 14 of 24
Assembling DF2 system
1. Gather all parts for desk including tabletop.
2. Turn tabletop upside down.
3. Fix beam length.
3.1. Extend beam to required length (width 1150 to 1750 mm), adjustable in 50 mm steps).
The beam must not be pulled completely apart in order not to pull the drive shaft apart.
Minimum adjustment in the connection end is 100 mm (to keep power and RJ45 sockets accessible),
otherwise adjustable in 50 mm steps.
Installation
Check the packaging and the delivered items for visible damage and ensure that the drive shaft
is mounted correctly and not pulled apart.
