Young children should be supervised to ensure that they do not play with the
appliance.
Before installation, re-installation, or troubleshooting:
• Stop the DL1A
• Switch off the power supply and pull out the mains plug.
• Relieve the DL1A 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 of the control box is correct before the system is
connected to the mains.
Important information
Important information on LINAK®products can be found under the following
headings:
Warning!
Failure to comply with these instructions may result in accidents involving
serious personal injury.
Failing to follow these instructions can result in the product being damaged
or being destroyed.

Repairs
In order to avoid the risk of malfunction, all DESKLINE®repairs must only be carried
out by authorised LINAK workshops or repairers, as special tools must be used and
special gaskets must be fitted. Lifting units under warranty must also be returned to
authorised LINAK workshops.
Warning!
If any of the DESKLINE®products are opened, there will be a risk of
subsequent malfunction.
Warning!
The DESKLINE®systems do not withstand cutting oil.
(continued)
• 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.
• The products must only be used in an environment, that corresponds to their
IP protection.

Misc. on the DESKLINE®DL1A system
This system is a DESKLINE system developed for desks and for indoor use. 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
There is a 36 months’ warranty on the 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 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.
The cleaners and disinfectants must not be highly alkaline or acidic
(pH value 6-8).
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.

Description of the DESKLINE®DL1A system
Each DESKLINE®DL1A actuator 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.
The DESKLINE®DL1A system range contains the following products:
• 1 control box CBD4/CBD5/CBD6
• 1 single DL1A 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.)
Options:
• Possibility of running extra actuators (LA31 with hall)
Application of the DESKLINE®DL1A 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.
Maximum load for each DL1A: 1600 N
Maximum load for a system with CBD4 400 W: 3200 N
Maximum load for a system with CBD4 600 W: 4800 N
Maximum load for a system with CBD5 500 W: 3200 N
Maximum load for a system with CBD6 375 W: 2400 N

Mounting guidelines for the DESKLINE DL1A
The lifting units are normally mounted with the motor housings upwards and
pointing towards each other (see figure 2).
The aluminium motor housing is supplied with 6 pcs. of M6 threaded holes
meant for mounting on the desk frame. The threaded holes are rolled into
the aluminium housing.
It is recommended to use all 6 M6 threaded holes. As the tabletop amplifies
the sound we advise you to place a vibration/shockabsorbing material
between the tabletop 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.

Mounting bracket
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.
The DESKLINE®DL1A 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 tabletop.
