Failing to follow these instructions can result in the product being
damaged or being destroyed.
Safe use of the system is possible only when the operating instructions
are read completely and the instructions contained are strictly observed.
Failure to comply with instructions marked with the ”NOTE” symbol may
result in serious damage to the system or one of its components.
It is important for everyone who is to connect, install or use the

Manual. Follow the instructions for mounting – risk of injury if these
instructions are not followed.
The appliance is not intended for use by young children or infirm
persons without supervision.
If there is visible damage on the product, it must not be installed.
Note that during construction of applications, in which the actuator
is to be fitted, there must be no possibility of personal injury, for
example squeezing of fingers or arms.
Assure free space for movement of applications in both directions
to avoid blockade.

Before installation, reinstallation, or troubleshooting
• Stop the DB/DL.
• Switch off the power supply and pull out the mains plug.
• Relieve the DB/DL of any loads, which may be released during the work.
Before start-up:
• Make sure that the system has been installed as instructed in this User
Manual.
• Make sure that the voltage at the control box is correct before the
system is connected to the mains.
• System connection. The individual parts must be connected before the
control box is connected to the mains. See the User Manual for LINAK
actuators, if necessary.
During operation:
• If the control box makes unusual noises or smells, switch off the mains
voltage immediately.
• Take care that the cables are not damaged.
• Unplug the mains cable on mobile equipment before it is moved.
Misc.
The actuator system has a sound level below 55dB(A) in typical
applications.

Misc. on the DESKLINE®system
Warranty
There is a 36 months’ warranty on DESKLINE products against manufacturing faults from the production date
of the individual products (see label).
LINAK A/S warranty is only valid in so far as the equipment has been used and maintained correctly and has
not been tampered with. Furthermore, the system must not be exposed to violent treatment. In the event of
this, the warranty will be ineffective/invalid. For further details, please see standard terms of sale and delivery
for LINAK A/S.
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 connection to electrical earth (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.
The 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 CBD4/CBD5/CBD6 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 CBD4/CBD5/CBD6
• DL12, DB12, DL14, DB14 or DL17 (1 - 4)
• 1 exchangeable mains cable
• motor cables (1 - 4)
• 1 DP1U/DPF1M (if memory function is required) DP1C//DPT/DPF1C (if memory function and display
are required) or 1 DPA/DPB/DP1K/DP1V/DPFK (if only up/down is required).
