Misc. on the DESKLINE® DL8/DL9/DL10/DL11 system
Warranty - 60 months on DESKLINE® (NEW)
This will be valid for all DESKLINE® products produced after the 1st of May 2015.
Products produced before 1
st
of May 2015 will still be covered by 36 months.
Products used in DESKLINE application: If these products are used in another application, they will be covered by 18 months
warranty.
If there is any doubt that returned products are within the warranty period it is to be treated as if they are covered by the
warranty. We recommend that you use the date of the Control box or actuator as reference if possible. We will have our
purchase no. printed on the label.
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 uneven 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 an overheating of the motor and control box. Exceeding the duty cycle will result in
a dramatic reduction of the life of the system.
The system range contains the following products:
• 1 control box CBD4/CBD5/CBD6
• DL8, DL9, DL10 or DL11 (1 - 3 (4))
• 1 exchangeable mains cable
• motor cables (1 - 3 (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) or DPF1D (if display is required).

Mounting guidelines for the DL8/DL9/DL10/DL11 system
Mounting guidelines for DL8/DL9/DL10/DL11 (motor housing)
The motor housing is supplied with 6 M6 threaded holes meant for mounting onto the desk frame. We advise you to fasten the
desk frame by means of 6 pcs. M6 screws of a good quality (min. 8.8) 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.
It is recommended to use all six M6 threaded holes to mount the desk frame. The values of the bending moments of
the lifting units are only valid if the desk frame is mounted in this way. Tests with fixing the motor housing only by
means of the 4 threaded holes have proved that this is not enough to obtain a sufficient torsional stability of the desk.
The column may not be twisted. If the column is twisting / rotated it may cause a failure. The maximum moment that
the column can adapt in the rotation direction is 200 Nm.
Use all 6 threaded mounting holes M6 for screws.
Thrust moment is 7.5Nm
DL motor housing: be aware of the screw length.
