How to Fit the TR-Auto Closer System

 

TR-Auto Closer Fitting Instructions

The TR-Auto comprises a balanced, integral 3-hinge/closer configuration. It provides maximum control for left or right-hung doors of all shapes, including arched forms, up to 80 kg/176 lbs. No rebating is required.

  • Fit the Spring Hinge at the top of the door as shown, with the nut adjuster facing downward. This hinge controls the power of the door. If the door weighs more than 80 kg/176 lbs, fit a second Spring Hinge in the position shown on the diagram.
  • Fit the Hydraulic Hinge at the centre point of the door, as show, with the adjusting screw facing upwards. This hinge controls the door's speed.
  • Fit the Anti-distortion Hinge at the bottom of the door, as shown.

Recommended spacing

Spring Hinge - 110 mm. from top edge of door. If two Spring Hinges are required, the top of the second hinge should be 60 mm from the bottom of the first.

Hydraulic Hinge - Midway between the Spring and Anti-distortion hinges, close to the horizontal centre line of the door.

Anti-distortion hinge - 110 mm. From the bottom edge of the door.

 

The gap between door and frame should be 3 mm/.12 in. 'UL' standard.

 

Planning Flange Positions

Important: Allow for gap between door and frame when planning flange positions.

Read These Installation Notes Carefully

  1. Fitting to an old, previously rebated door. Old rebates must be refilled with pinned and glued timber inserts and the surfaces made true and level before fitting the TR-Auto System hinges.
  2. First things first: The frame flags of hinges must be fitted first.
  3. Top Flags: Depending on whether you are fitting to a right or a left-hung door, the hinge flag you must fit to the door will have an "R" or an "L" on the upper flag of the hinge.
  4. Square Shoulders: Fit the square shoulders of the hinge flags against the door and frame as shown in the diagram.
  5. One, Two, Three: Start by fitting the top Spring Hinge and the bottom Anti-distortion hinge. Install the hydraulic hinge last. This is essential in order to give the door a firm latching action.

 

Guidelines for Set-up and Custom-Tuning

With MDC's TR-Auto System, you can adjust the rate of door closure to your customer or user preferences. Factors such as heat, damp and cold or - on old door frames - the existence of strips previously fitted to the door frame can all affect smooth door closure. To achieve the optimum closure rate for your needs and ensure firm latching, you may need to fine tune the Spring Hinge, which provides the door's power. Here's how to do it:

  • The Spring Hinge has six (6) settings. Using the MDC spanner provided (or a socket spanner), turn the adjuster nut in the direction the door is going to close. Insert the small pin to hold the setting chosen.
  • Test and tune until you can see and feel the correct tension during closure. As a guideline, setting 3 or 4 is usually most efficient in an average hanging environment.
  • Hold the door open at 90 degrees and release it. Ensure that the door closes and latches firmly.
  • Finally fit the TR-Auto hydraulic hinge and adjust the set up according to your requirements.
