Original document

Technical specifications

1.1 Overview
These instructions are for installation of MUTO COMFORT sliding door system L80 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 optional 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.
TIPS AND RECOMMENDATIONS
Information note

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.

2.2 Securing track to mounting surface
Fig. 1

2.2.1 Ensure the track is properly level and secure it to the ceiling per the appropriate measurements on the following page.
NOTE: SEE DIMENSION INSTRUCTIONS ON NEXT PAGE FOR REFERENCE.
2.2.2 Use appropriate fasteners according to the following recommendations.
NOTE:
OVERHEAD REINFORCEMENT:
The overhead reinforcement must be a minimum of ¼” [6] x 3” [76] steel angle, 16 gauge metal stud, or two pieces of 1-1/2” [38] thick wood blocking [double stacked], secured to studs or joists on a maximum 16” [406] centers for the length of the track. The overhead reinforcement may be flush on the overhead surface or on the interior of this surface.
Track mounting screws must fully penetrate the steel angle, metal stud, or at a minimum of 2” [51] into wood blocking, utilizing the predrilled holes in the MUTO track.
Consult with a structural engineer to determine if reinforcement is adequate for your specific application or to meet specific codes in your location.
