Concealed installation of the slide drive SA
In the case of concealed installation of the slide drive SA (e.g. suspended ceiling), it must be possible to access and disassemble
the slide drive at all times should maintenance and service work be required (see fig.).

2.13 Finalising the assembly
Checking the functionality of the lift & slide element manually with the MHS400 system installed
So that friction and resistance can be identified during manual operation of the lift & slide sash, the MHS400 system should
be decoupled from the sash. To do this, simply release the catch on the slide drive SA from the catch base on the lift & slide
sash and pull out the plug of the connection cable for the lift drive HA in the slide drive SA.
Possible causes of malfunctions affecting the MHS400
• Changes to the lift & slide element following assembly of the MHS400 system (e.g. changes to
stoppers, end pieces, etc.)
• Seals on lift & slide element too stiff or not fitted correctly
• Seal lip is rubbing against the guide rail
• During travel, the cable holders in the sash groove at the top are rubbing against the guide rail
• The front and rear guides at the top are not positioned correctly in the sash groove (e.g. installed too high up)
• The lift & slide element has been installed warped and/or at an angle or not vertically plumb in the reveal
• Threshold not aligned precisely horizontally
• Heavy soiling on or significant damage to the running rail
• Thermal characteristics of the material not taken into account (e.g. continuous exposure to direct sunlight, dark shade of the lift
& slide element components)
• Lift & slide element not glazed or wedged properly
The causes should be remedied by qualified professionals taking the appropriate actions.
Finalising the assembly
Following assembly and connection to the AC mains power supply, you must carry out a reference run as well as a calibra-
tion and teach-in run (see operating instructions).
