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

Misc. on the DESKLINE® DL5/DL6 system
Warranty
There is a 36 months’ warranty on the DESKLINE products against manufacturing faults from the production date of theindividual 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 beineffective/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 IIA Class II or double insulated electrical appliance is one which has been designed in such a way that it does not require asafety 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 anelectric shock and that this is achieved without relying on an earthed metal casing. This is usually achieved at least in part byhaving 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 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 control box. Exceeding the duty cycle will result ina dramatic reduction of the life of the system.
The system range contains following products:• 1 control box CBD4/CBD5/CBD6• DL7/DL7R (1 - 4)
• 1 exchangeable mains cable• motor cables (1 - 4)
• 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/DPFK/DPF1K (if only up/down is required.)Page 9 of 24

Mounting guidelines for the DL7
Mounting of the top frame
There are 2 ways to mount the motor housing to a top frame. Either use the 2 outer placed holes on the short side of the
motor housing and nut and bolt or use the 2 inner placed holes on the short side of the motor housing with thread (M8) andscrews. If you choose the screws, we advise you to fasten the desk frame by means of 4 pcs. of M8 screws of a good quality
and a suitable length, which must not go further into the motor housing than max. 30 mm.
We advise you to use the 6 pcs. of ø6 holes for mounting the tabletop.
Mounting of the footThe DL7 is to be mounted on the foot by using 2 pcs. of
M8 screws of a good quality and a suitable length, whichmust not go further into the column than max. 30 mm.

Always place the DL7 column on top of the foot construction due to the upside down design.

Mounting guidelines for the DL7R
Mounting of the top frame
There are 2 ways to mount the motor housing to a top frame. Either use the 2 outer placed holes on the short side of the
motor housing and nut and bolt or use the 2 inner placed holes on the short side of the motor housing with thread (M8) andscrews. If you choose the screws, we advise you to fasten the desk frame by means of 4 pcs. of M8 screws of a good quality
and a suitable length, which must not go further into the motor housing than max. 30 mm.

Mounting of the footThe DL7R is to be mounted on the foot by using 4 pcs. of
M6 screws of a good quality and a suitable length, whichmust not go further into the column than max. 30 mm.

Always place the DL7R column on top of the foot construction due to the upside down design.

Example of how to mount the DL7R DESKLINE® system

Page 11 of 24

LINAK recommends that the DESKLINE® DL7/DL7R system should be used in push applications.
Placement of a monitor directly above the motor 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, some what larger
than the profil between the motor and the tabletop.
The mounting screws on the DP or DPA must be fastened with a max. torque of 1 Nm.

Page 12 of 24

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 thesurroundings. 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 canbe used to bypass the CBD for both motorcables and the mains cable (EU version only) from one side to the other, giving acleaner 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.

Electrical connection of the DL7 system:
The systems is to be connected as shown on figure 7. Each DL7/DL7R is to be connected to the sockets on the control box bymeans of the motor cables, which have an 6-pin plug in each end.

Finally the mains cable is to be mounted and power switched on. Please note that the control box must only beconnected to the voltage stated on the label.

Initialisation of the DESKLINE® DL7 parallel system
To obtain parallel operation of a DESKLINE® system it is necessary that the system at first activation drives the lifting units DL7
in end stop position bottom. Thus the control box CBD4/CBD5 registers the bottom position for each lifting unit.
Besides the system has to be initialised when exchanging the lifting units or the control box.
Forced initialisation under normal operation is done by driving the DL7’s into end stop at the bottom. Pushing the down button
again within 10 sec. will start the initialisation after 1.25 sec delay.
The button must be pressed during the full sequence.

When using the DL7R, the stroke length must be configured to 470 mm prior to use.

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 thatenables a classifi cation to different waste fractions for recycling or combustion.
Guidance
We recommend that our products be disassembled as much as possible anddivided 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 andplastic 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:
