The TWINDRIVE™ TD1 is a completely new
product, which is part of the Comfort furniture
group and has been produced to supply the
growing demands for motorised systems in the
leisure bed area.
TD1 is characterised by the very low built in
height, which makes it unique in this market
and gives much more free height under the bed
than previous systems for e.g. storage or easy
cleaning access.

Compatible actuators:
Actuators that are compatible with TD1:
LA31
LA27
Cable for LA27
The cable used together with LA27 has to ordered separately:
LA27
(0705816)
Cable for LA31
The cable used in combination with LA31 is not possible to choose in the respectable ordering examples for the actuator. To
avoid any confusing write X when stating the cable and specify the cable as 0705825.
LA31
(0705825)
LA31 with fast motor cannot be used in combination with TD1
Always choose LA27 and LA31 without brake otherwise there will it not be enough power in the 2 x 9 Volt batteries
for emergency lowering. In some cases where a standard HB is to run head, foot motor and the external actuator
simultaneous down it can happen that the actuator not will start if a brake is mounted. In the TD1 280 system with
memory and infrared the current cut-off down is not sufficient to start up the extra actuator if a brake is chosen.

Mounting instructions:
Before mounting, both mounting brackets must be pulled out to their outer position by pushing them back.
This gives freedom of movement to the bed bracket.
Mounting is done by pushing the bed bracket into the TD1 unit and thereafter pushing the mounting brackets back again.
IMPORTANT one must be completely sure that the mounting brackets are in place before TD1 is used.
If the TD1 unit is mounted in the bed it will not be able to fall out if it is under load because the spindle nut is designed to
hold it in place.

Mounting instructions for TWINDRIVETM:

Mounting instructions (welding):
Welding diagram:
To maintain the correct angle of rotation of the head rest and the foot rest it is important that the Twist bracket is welded
according to the above instructions. Non compliance with the instructions could lead to a smaller angle of rotation or in a
worst case damage to TD1.
Dimensions drawing of the twist bracket:
LINAK part number 0701030
For the TD1 it is important that one does not weld on the outside of the Twist Bracket because there is not room for a
welding seam in the motor housing. One may weld the bracket along the whole length of its ends.

Removal / fitting of the 9V batteries:
Changing of the 9V batteries is possible by pushing the batteries upwards via the two holes in the bottom of the unit.
It is necessary to use a blunt instrument with a diameter of Ø6 mm. When the batteries are visible from above they can be
removed by using fingers.
Important, before removal remove the battery clips. Fitting is done by pushing the batteries into the holes remembering
that the clips must be uppermost and that they are first connected when the batteries are in place.
If the battery option is chosen the system will be able to be lowered into the reset position by using the reset button on the
handset during power failure.
This function is only available for the head and foot rest and only when the emergency lowering function is an available
option.
Initialisation of the TD1 memory and infrared system.
To ensure optimum drive of the systems with memory, infrared and extra channels must be
run out to the outward position and in again before use. This drive (out + in) must be done
without stops.

Speed diagram:

Maximum torque occurs with a non-linear load as prevails under use in a leisure bed. That is to say large torque during
start, which lessens as the backrest is raised. This is also how the TD1 has been tested.
