  2. For right side door hang use right handed hinges.

Method of Installation

The TR-AUTO Door Closer System comprises three hinges:

  • A SPRING hinge fitted at the top of the door with nut adjuster facing downwards.
  • A HYDRAULIC hinge fitted at the middle of the door with the adjusting screw facing upwards.
  • A GENERAL hinge fitted to the bottom of the door.

Recommended spacing:

  • SPRING hinge 150mm from the top of the door.
  • GENERAL hinge 150mm from the bottom of the door
  • HYDRAULIC hinge equally between the two or as practicable

Important points:

  • The flag that has the R or L marked on it is the upper flag and is to be connected to the door.
  • The frame flags should be fitted first.
  • The square shoulders on the flags must be fitted against the door and frame as shown on the drawing detail.
  • The flags must be fitted directly onto the door and frame. Do NOT rebate the door or the frame.
  • A firm positive latching action must be achieved with the SPRING and GENERAL hinge first BEFORE connecting the HYDRAULIC hinge.
  • If the TR-AUTO hinge system is to be fitted to old doors and frames then the old hinge rebates must first be refilled with pinned and glued timber inserts and their surfaces made true and level.

Guide lines for set up and tuning.

Install the SPRING and GENERAL hinges first.

  • The SPRING hinge provides the power to close the door.
  • This hinge has six settings. Using a socket spanner or the spanner provided, turn the adjuster nut towards the way the door is going to close until you have the correct tension for that weight of door.
  • Insert the small pin. As a guide the third or fourth positions are usually the most efficient in the majority of normal hanging environments.
  • Hold the door open at ninety degrees, then release it to see if the door closes with a firm latching action. If it does move the door backwards and forwards a few times to see if there is a smooth action and not binding anywhere.
  • Check closing and latching actions.
  • It maybe necessary to adust the settings a few times to take into consideration the various strips which maybe fitted to a door frame and particular operating environments.

Now install the HYDRAULIC hinge.

  • This hinges controls the smooth closing action of the door. On the adjustment screw make sure the cut in the screw where the screwdriver fits in is level with the top of the barrel of the hinge. Take a flag in each hand and move backwards and forwards 180 degrees to check for a smooth action. In one direction there will be a resistance and in the other there will be free movement. Closing arc resistance, opening arc mechanism is released for easy opening. Hold open door at 90 and release to check for free movement.
  • Fit the Hydraulic, hold open at 90 and let go to see that there is still latching action. Hold open at 90 again but this time adjust the screw a quarter of a turn and keep repeating the action until the door slows down but still latches properly.

Troubleshooting Tips

If latching is difficult to achieve with the Standard set then it might be useful to reposition the Hydraulic. By lowering the Hydraulic 5 or so cm this will decrease the damping affect but then restart the adjustment from fresh again. Equally if you raise the hydraulic by the same amount you are increasing the damping affect.

Whenever you have to re-adjust the hydraulic you always have to start the process with the adjustment screw wound out with the cut level with the top of the barrel. If there are still problems then you will have to convert to the Non Standard Set. Instructions further on in the booklet.

On new builds always make sure the doors and frames are true and at the correct moisture level. If you install a door that is soft wood and not properly dried out then at a later date, as it dries out, you MAY have to revisit and reset.

On refurbishments when packing the rebate where the old hinges were make sure it is glued as well as tacked and level with the surface. The shoulder of the hinges need to be well butted to the frame and the door and firmly screwed in. The screws provided are a general purpose screw but in some cases where the frames or doors are laminated or very old a longer screw maybe necessary.

Check that the vertical alignment is true.

There should be the same 3mm gap at the bottom of the door as well as the top on the hinge side of the door.

If a Spring Hinge starts to squeak it means that the place where the Hydraulic Hinge is installed is uneven or twisted. First disconnect a flag of the Hydraulic hold the door open at 90 degrees and let go. If the Spring Hinge is squeaking then replace. Second you need to find a place on the door where the surface is even or not twisted. This may mean moving the Hydraulic up or down a little and screw in firmly. Then set up in the normal manner.

Check List

Is the frame and the door butted up firmly against the shoulder on the flag?

Is the gap on the frame side of the door equal at the top and bottom of the door?

When you move the door backwards and forwards a couple of times is it a nice smooth action?

Are the two sections of each hinge in perfect vertical alignment?

The hydraulic is very powerful but the adjusting screw needs to be started from the same position as when you first started if you have to re-adjust the Spring tension.

If hung correctly the door should close at a linear speed for the full arc and latch. When unlatched to open you should be able to push the door open with your little finger.
