Misc. on the DESKLINE®DL15/DL16/DB16 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 environments 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 error situations.
Warranty
There is a 36 months’ warranty on the DESKLINE products against manufacturing
calculated 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 LINAK A/S’ ordinary conditions of
sale.
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®DL15/DL16/DB16 system
Each DESKLINE®DL15/DL16/DB16 lifting unit 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 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®DL15/DL16/DB16 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, the brake and the spindle nut. Exceeding the duty
cycle will result in a dramatic reduction of the life of the system.
The DESKLINE®DL15/DL16/DB16 system range contains the following products:
• 1 control box CBD4/CBD5/CBD6
• 1 single DL15/DL16/DB16 or 2, 3, or 4 parallel
• 1 exchangeable mains cable
• 1, 2, 3, or 4 motor cables
• 1 DP1U/DPF1M (if memory function is required) DP1C/WDPL/DPT/DPF1C (if
memory function and display is required) or 1 DPA/DPB/DP1K/DP1V/DPF1K (if only
up/down is required.)

motor housing
The lifting units are normally mounted with the motor housings upwards
and pointing towards each other (see figure 2).
The steel motor housing is supplied with 6 pcs. of M6 threaded holes meant
for mounting on the desk frame.
It is recommended to use all 6 pcs of M6 threaded holes. As the table top
amplifies the sound we advise you to place a vibration/shock-absorbing
material between the table top and the table frame.
A suitable desk height in the lowest position can be obtained by mounting the
lifting unit on a 6-8 mm bottom plate by means of 4 pcs. of M6 countersinked
screws. We recommend you to use screws of min. quality 8.8. The thrust moment
must not exceed 10 Nm in the bottom plate thread.
The motor housing is supplied with 6 pcs. of M6 threaded holes meant for mounting
on the desk frame. We advise you to fasten the desk frame by means of 6 pcs. of M6
screws of a good quality and a suitable length, which must not go further into the
motor housing than max.10 mm. The thrust moment must not exceed max. 7.5 Nm.

Figure 3
(Example of how to mount a 2 parallel DESKLINE® DL15/DL16 system)
To avoid damage of the lifting unit there must be min. 1 mm space between
the end of the screw for the mounting bracket and the surface of the lifting
unit (see figure 1). The use of any longer screws will come into contact with
the inner parts. This will result in an irregular operation or even damage the
lifting unit.
10
The DESKLINE®DL15/DL16/DB16 system can only be used in push
applications with the motor housing mounted upwards.
Placement of a monitor directly above the motor housing may cause
malfunction of the monitor. Magnets inside the motor may interrupt the
picture on the monitor depending on the distance and type of monitor. If
this is the case the problem may be solved by placing an iron plate/tube
or another magnetic material, somewhat larger than the motor housing,
between the motor, and the table top.
The end stop system in the DB6 is based on a buffer system meaning that
you must be aware of the lengths when initialising. The products must be
able to drive:
Inwards direction: built-in dimension - tolerances – 5 mm
Outwards direction: built-in dimension + stroke length + tolerances + 5 mm

11
Mounting guidelines for the DB16 system
The motor housing is supplied with 6 pcs. M6 threaded holes meant for mounting
on the desk frame. We advise you to fasten the desk frame by means of 6 pcs. M6
screws of a good quality and a suitable length, which must not go further into the
motor housing than max.10 mm. The thrust moment must not exceed 7.5 Nm.
The motor housing can also be mounted by using 2 no. M6 screws with 10 mm
diameter heads fitted through the two uppermost holes (as shown).

12
It is important that the correct screws are used. Check that the screws are
fitted correctly to ensure a correct function in order to prevent the guidance
from coming apart when the desktop is lifted.
As the desktop amplifies the sound, we advise you to place a vibration/
shock absorbing material between the desktop and the desk frame.

13
Mounting guidelines CBD4/CBD5/CBD6
The control box is to be fastened with 4 screws (3 screws for CBD5 and CBD6) with
a head diameter between ø 8 and ø 10 mm. Out of regard for the tension surface
ø 10 mm is preferable due to lower surface tension. See drawing appendix for
placing of mounting holes and the space the CBD takes up.
CBD4 - Control box CBD5 - Control box CBD6 - Control box
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.
CBD6 - bottom with cable grooves
The bottom of CBD6 is equipped with two cable grooves improving the cable
management when mounting. The grooves can be used to bypass the CBD for
both motorcables 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.

14
Electrical connection of the DL15/DL16/DB16 system:
The DESKLINE®DL15/DL16/DB16 system is to be connected as shown on figure 4.
Each DL15/DL16/DB16 is to be connected to the sockets on the control box by
means of the motor cables, which have an 6-pin plug in each end.
Please note that the control box must only be connected to the voltage stated
on the label.
Voltage must not be connected to the CBD4/CBD5/CBD6 until all actuators/
legs have been connected. This must be observed to ensure that the CBD4/
CBD5/CBD6 can detect, which actuators/legs have been connected.
Finally, the mains cable is to be mounted and power switched on.
CBD4/CBD5/CBD6 with earth
The CBD4/CBD5/CBD6 earth cable to be mounted on the desk construction
(typically the top frame)in a way that ensures good electrical contact. The function
of the earth cable is to earth the desk and ground static electricity. The earth
connection does not protect other electrical products.
CBD4/CBD5 with mains cut-off (non ZERO models)
If the power cable is damaged it has to be replaced by an authorized LINAK
service centre to avoid any danger.

Initialisation of the DESKLINE DL15/DL16/DB16 parallel systems
The DESKLINE system is intialised by pressing the down button once or twice and
holding it down until the DL15/DL16 runs into end stop. It will then automatically
run approx. 3 mm out again and hereafter slowly run in again. Only release the
down button when the movement has completely stopped.
If the button is released before the sequence is completed then the
initialisation is interrupted and must be started again from the beginning.
It is sometimes necessary to press the down button twice to start the initialisation,
this is because the system can be in different modes when the initialisation starts.
The CBD5 and CBD6 can control DL15 and DL16 in 2 parallel while the CBD4
can control DL15 and DL16 in 2, 3, and 4 parallel so that the desk is always kept
horisontal.

Disposal of LINAK’s products
As LINAK’s customers often ask us how our products can be disposed of or
scrapped we have prepared this guidance that enables a classification to different
waste fractions for recycling or combustion.
Guidance
We recommend that our products be disassembled as much as possible and divided
into different waste groups for recycling or combustion.
For example, waste can be sorted into metals, plastics, cable scrap, combustible
material, and recoverable resources.
Some of these main groups can be further divided into subgroups; e.g. metal can be
divided into steel/aluminium/copper and plastic can be divided into ABS/PA/PE/PP.
As an example, the table below breaks down the different components in LINAK
products to various recycling groups:
