Technical specifications
. Overview
These instructions are for installation of MUTO
PREMIUM sliding door system XL with Sidelites
(glass door) for the following mounting and style
versions:
. Ceiling mount
.. General information
• dormakaba requires use of tempered monolithic or
tempered laminated glass.
• dormakaba glass hardware is not suitable for
application in rooms where chemicals (e.g. chlorine)
are used as indoor swimming pools, saunas or
salt-water pools.
• Never move sliding panels faster than walking
speed and always stop the door manually before it
reaches end position.
• Do not slide doors with excessive force. Install
limiting stop to prevent door from opening too far.
.. Intended use
• For sliding door in dry indoor areas only
• For manual slowly opening and closing only
.. Glass requirements and fittings
• The substructure/wall must be able to bear
permanent loads and be level (max. tolerance:
/” [] per ” [m]).
• Fasteners must be sufficiently dimensioned for the
substructure/wall and weight of the door.
• When adjusting glass components, always stick to
the required clearance for the respective
hardware. Adjust clearance so glass does not
come in contact with any hard surfaces such as
glass, metal or concrete.
• Do not use excessive force when installing the
glass (avoid over tightening screws).
.. Requirements for glass panel
• dormakaba requires use of fully tempered glass,
which complies with ASTM C and ASTM C
. Secondary heat soaking processes are
recommended but not required. This applies to
both tempered monolithic and tempered laminated
glass.
• Clamping area must be flat and uncoated (no
self-cleaning coating!)
• Never use glass with conchoidal fractures and/or
damaged edges.
.. Safety instructions
• Installation requires two people.
• Only properly qualified and specially trained staff
are authorized to mount dormakaba glass
hardware.
• Due to crushing hazards and possible injury caused
by breakage of glass during mounting,
corresponding protective clothing (especially gloves
and protective goggles) is required.
• Never clamp metal fitting hardware directly to
glass surface.
.. Symbols used - Safety/Installation
CAUTION
Mounting components must meet the
requirements of substructure/wall and door
weight. Please read the technical information
for fittings.
WARNING
Risk of breaking glass. When installing the
door, support the door panel with a block of
wood or similar object.
TIPS AND RECOMMENDATIONS
Information note
CLOSING EDGE
.. Maintenance, care, repair
• Immediately replace damaged parts.
• Always use original dormakaba parts.
• Clean clamping area with alcohol-based standard
commercial cleaning agent before mounting the
glass hardware.
• Use a damp clothe for occasional cleaning,
especially the track.
• Always use silicone - and oil-free cleaners (e.g.
acetone).
• Check glass hardware at regular intervals for
proper positioning and smooth operation and
correct adjustment.
• High traffic door systems require inspection by
properly qualified staff (specialized companies or
installation firms.)
.. Disposal
Disposal in accordance with local, state and national
regulations.
