Misc. on the DESKLINE®system
This system is a DESKLINE system developed for desks and for indoor use in offices. Do not use it in industrial kitchens or in
other enviroments that have to be cleaned with aggressive detergents.
Do not bolt the legs to the floor so that free movement is prevented. This could cause serious damage to the legs in fault
situations.
Warranty
This DESKLINE product is subject to warranty pursuant to the terms of LINAK DESKLINE Warranty Paper, available on the LINAK
website www.linak.com/warranty.
Maintenance
Clean dust and dirt on the outside of the system at appropriate intervals and inspect them for damage and breaks.
Inspect the connections, cables and plugs and check for correct functioning as well as fixing points.
Service of double insulated products:
Class II
A Class II or double insulated electrical appliance is one which has been designed in such a way that it does not require a
safety electric earth connection (US: ground).
The basic requirement is that no single failure can result in dangerous voltage becoming exposed so that it might cause an
electric shock and that this is achieved without relying on an earthed metal casing. This is usually achieved at least in part by
having two layers of insulating material surrounding live parts or by using reinforced insulation.
There is no earthing/grounding means provided on the product, and no earthing/grounding means is to be added to the
product.
In Europe, a double insulated appliance must be labelled “Class II”, “double insulated” or bear the double insulation symbol
(a square inside another square).
Servicing a double-insulated product requires extreme care and knowledge of the system, and is to be done only by qualified
service personnel. Replacement parts for a double-insulated product must be identical to the parts they replace.
Cleaners and disinfectants must not be highly alkaline or acidic (pH value 6-8).

Description of the DESKLINE®system
Each DESKLINE®actuator/column is equipped with a motor and parallel/memory drive is ensured by means of software in the
CBD6S (SMPS) that also takes account of an oblique load on the desk. Soft start and stop are also part of this software, which
ensures a soft start and stop when adjusting the desk.
Application of the DESKLINE®system:
Irrespective of the load, the duty cycle 10% ~ 6 min./ hour or max. 2 min. at continuous use stated in the data sheets,
must NOT be exceeded as this will result in a superheating of the motor and the control box. Exceeding the duty cycle will
result in a dramatic reduction of the life of the system.
The DB/DL system range contains following products:
• 1 control box CBD6S 200W or CBD6S 300W (SMPS - Switch Mode Power Supply)
• DL12, DL14, DB14 or DL17 (1 - 4)
• 1 exchangeable mains cable
• Motor cables (1 - 4)
• DP1U/DPF1M (if memory function is required)
DP1C/DPT/DPF1C (if memory function and display is required)
or DPA/DPB/DPH/DP1K/DP1V/DPF1K/DPG1K (if only up/down is required)
or DPF1D (if display is required),
or DPG1M/DPG1B (if reminder, Bluetooth®and memory is required)
or DPG1C (“If reminder, Bluetooth®, memory and display is required)

From the factory, the DB14 is delivered with the hollow spindle driven into end position. Please observe that the
solid spindle may roll out during transportation/handling, but it must be rolled back to end position before mounting
in the profile.
As the desktop amplifies the sound,we advise you to place a vibration/shock absorbing material between the
desktop and the desk frame
Do not drive the DB14 to the outer end position before mounting. This will damage the DB.
Bottom plate with groove and spline
Mounting the middle tube
The DB14 gives the possibility of synchronous drive of the middle profile. To make sure that the profiles are in the
right place, you have to ensure that both the hollow and the solid spindle are driven into end position. For detailed
information on how to mount the middle tube of your column, please contact DESKLINE Technical Support at
LINAK A/S.
Mounting the bottom
At the bottom of the DB14 the inner spindle should be mounted by means of a 22 teeth spline profile and an M5 screw in the
bottom of the spindle. Max. torque: 2.3 Nm.
The bottom plate should have a groove for the locking ring.
A cut-out in the inner profile is required for cable relief.
Note:

Page 20 of 40
The CBD must not be packed in heat insulating material, but must be placed so that it can emit waste heat into the
surroundings. There are no ventilation holes to consider, the CBD emits heat through the surface.
The plug must be visible when the CBD is mounted so that the supply to the CBD can be disconnected at replacement, if any.
The mounting screws on the control box must be fastened with a max. torque of 1 Nm.
The mounting surface to which the control box is attached should have a surface evenness of better than ±0.5 mm.
Bottom with cable grooves
The bottom of the CBD6S (SMPS) is equipped with two cable grooves improving the cable management when mounting. The
grooves can be used to bypass the CBD for both motor cables and the mains cable (EU version only) from one side to the
other, giving a cleaner design.
Remember to lead the cables through the grooves before mounting the control box.
For mounting and operation of the desk panel, please see the separate user manual for desk panels.
Mounting guidelines for the CBD6S (SMPS)
The control box is to be fastened with 2 screws with a head diameter between ø 8 and ø 10 mm. With regard to the tension
surface ø 10 mm is preferable due to a lower surface tension. See drawing appendix for placing of mounting holes and the
space the CBD takes up.
