Wall-mounted lift unit for worktop
Fault
Cause
Lift unit for
No power .
worktop without
safety rail
cannot be height-
adjusted.
Telescopic legs not
mounted at the same
height.
A sink or installation
cover collides with an
obstruction.
Lift unit has not been
reset (e.g. after power
loss).
Faulty plugs.
The frame-mounted
switch cannot be
operated easily.
Remedy
Check mains electricity is correctly
connected to the control box.
(The control box will usually be located
under the worktop).
Mount the telescopic legs at the same
height and level.
Check whether the installation cover
comes into contact with the skirting board
or the like.
Reset the unit if possible:
1. Activate the indicator until the unit is in
its lowest position. Release the switch.
2. Activate the lower indicator again for
5 seconds.
3. The lift unit is now reset. (It may be
necessary to reset the unit several times
in succession).
Check plug from motor to extension lead,
and those in inlets 1 and 2 on the control
box. The male plugs have small steel pins
which can be easily bent when inserted
into the control box. If one of the pins is
bent, straighten it out before replacing
the plug in the control box. REMEMBER
to reset.
Check whether the switch can be operated
freely and that it returns automatically to
neutral position. The movement can be
hindered by dirt or grease.
Check the frame-mounted switch:
Check that all wires are correctly
connected according to the installation
guide and that none are broken.
If a wire is incorrectly connected, the lift
unit cannot run up or down.
NB: If the lift unit will not rise, the switch
can be considered as defective.
If all wires from the switch are correctly
connected and none are broken, the
lift unit should be able to run up/down.
REMEMBER to reset.
