Technical specifications

1.1 Overview

These instructions are for installation of MUTO 
COMFORT sliding door system M50 for the following 
mounting and style versions:

1.  Ceiling mount

1.1.1

 

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.

1.1.2

 

Intended use

• 

For sliding door in dry indoor areas only

• 

For manual slowly opening and closing only

1.1.3

 

Glass requirements and fittings

• 

The substructure/wall must be able to bear 
permanent loads and be level (max. tolerance: 
1/16” [2] per 39” [1m]).

• 

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).

1.1.4

 

Requirements for glass panel

• 

dormakaba requires use of fully tempered glass, 
which complies with ASTM C 1036 and ASTM C 
1048. 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.

1.1.5

 

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.

1.1.6

 

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.

1.1.7

 

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.)

1.1.8

 Disposal

Disposal in accordance with local, state and national 
regulations.
