5. 設定與安裝

This section outlines the steps for installing your M-D Building Products threshold. Ensure you have the necessary tools before beginning.

所需工具：

• 捲尺
• 鉛筆或記號筆
• Hacksaw or Metal Cutting Saw (if cutting is required)
• Drill with appropriate drill bit for pilot holes
• 螺絲起子（手動或電動）
• 安全眼鏡和手套

安裝步驟：

1. 測量開口： Carefully measure the width of the doorway or opening where the threshold will be installed.
2. 裁切至所需尺寸（如有必要）： If the threshold is longer than your opening, mark the excess length and cut it using a hacksaw or metal cutting saw. Ensure a clean, straight cut.
3. Position the Threshold: Place the threshold in the desired position across the bottom of the door frame. Ensure it is centered and flush with the floor on both sides. The low-profile design should provide a smooth transition.
4. 標記導孔： Using the pre-drilled holes in the threshold as a guide, mark the locations for drilling pilot holes on the floor surface with a pencil or marker.
5. 鑽導孔： Remove the threshold. Using a drill bit appropriate for your floor material (wood, concrete, etc.), drill pilot holes at the marked locations. Ensure the depth is sufficient for the screws.
6. 確保門檻： Reposition the threshold over the pilot holes. Insert the provided mounting screws into the holes and tighten them securely with a screwdriver. Do not overtighten, as this can strip the screws or damage the threshold.

6. 操作說明

The M-D Building Products 68395 threshold operates passively as a permanent fixture. Once installed, it functions to:

• Provide a smooth, accessible transition between two floor surfaces, accommodating wheelchairs and reducing tripping hazards.
• Seal the bottom of the door opening to prevent drafts, dust, and moisture intrusion.
• Contribute to the fire rating of the door assembly when installed correctly with a compatible fire-rated door.

7、維護保養

To ensure the longevity and continued performance of your aluminum threshold, follow these simple maintenance guidelines:

• 定期清潔： Clean the threshold periodically with a mild soap and water solution. Use a soft cloth or sponge to wipe away dirt and debris. Avoid abrasive cleaners or harsh chemicals, as these can damage the aluminum finish.
• 檢查磨損情況： Periodically check the threshold for any signs of wear, damage, or loosening of screws.
• 擰緊螺絲： If any screws appear loose, gently tighten them to ensure the threshold remains securely fastened to the floor.
• 清除碎片： Keep the surface of the threshold clear of excessive dirt, grit, or other debris that could cause premature wear or impede smooth passage.

8。 故障排除

If you encounter issues with your threshold, consider the following:

• Threshold is Loose: Check if the mounting screws are securely tightened. If the pilot holes have become stripped, you may need to use larger screws or relocate the threshold slightly if possible.
• Drafts or Moisture Still Entering: Ensure the threshold is installed flush with the floor and that the door bottom seal (if applicable) makes proper contact with the threshold. Adjust the door or door sweep as needed.
• Difficulty with Wheelchair Passage: Verify that the threshold is installed correctly and that its low-profile design is maintained. Ensure no debris is obstructing the path.
• 刮痕或變色： Minor scratches can sometimes be buffed out with fine-grit sandpaper or steel wool, followed by a metal polish, depending on the finish. For discoloration, ensure only mild cleaners are used.
