6. Setup and Installation

Installation requires careful attention to detail. It is highly recommended to have two people for this process due to the weight of the door panels. A detailed installation manual is included with your product. The following is a general overview.

Tools Required (Not Included):

  • Measuring Tape
  • Pencil
  • Level
  • Drill and Drill Bits
  • Screwdriver (Phillips and Flathead)
  • Wrench (for hex bolts)
  • Stud Finder (if installing into drywall)
  • Wood Blocking (if necessary for wall support)

General Installation Steps:

  1. Prepare the Opening: Ensure the door opening is clean, plumb, and level. Confirm that the required 5-3/8" clearance above the opening is available.
  2. Install the Track: Mount the rail (track) securely above the door opening. Use a level to ensure it is perfectly horizontal. If installing into drywall, locate wall studs and use appropriate wood blocking for secure attachment. The track length is 34 inches.
  3. Assemble Door Panels: Attach the hinges to connect the two bifold door panels. Ensure they are aligned correctly.
  4. Attach Rollers and Brackets: Secure the rollers and roller brackets to the top edge of the door panels as indicated in the detailed manual.
  5. Install Floor Guides: Position and install the floor guides on the floor at the bottom of the door opening. These guides ensure the door panels move smoothly and stay aligned.
  6. Hang the Door: Carefully lift the assembled door panels and engage the rollers with the track. Ensure the door panels are properly seated in the floor guides. This step typically requires two people.
  7. Install Handle: Attach the handle to the door panel at a comfortable height.
  8. Adjust and Test: Gently open and close the door to check for smooth operation. Make any necessary adjustments to the rollers or floor guides to ensure the door slides freely without binding.

For precise measurements and detailed diagrams, refer to the dedicated installation manual included in your package.

7. Operating Instructions

Your JUBEST bifold door is designed for simple and smooth operation.

  1. Opening the Door: Grasp the handle firmly and gently pull the door panels towards you, then guide them along the track. The panels will fold inward as they open.
  2. Closing the Door: Push the door panels along the track until they fully extend and meet in the center, closing the opening. Ensure the panels are aligned and securely closed.

Avoid forcing the door if it encounters resistance. Check for any obstructions in the track or floor guides.

8. Maintenance

Regular maintenance will ensure the longevity and smooth operation of your bifold door.

  • Cleaning:
    • Wipe door panels with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the PVC surface or glass.
    • For glass panels, use a standard glass cleaner.
    • Keep the track clean and free of dust and debris. Use a vacuum cleaner or a damp cloth to remove any buildup.
  • Hardware Check: Periodically inspect all screws, hinges, rollers, and brackets to ensure they are tight. Tighten any loose fasteners.
  • Lubrication: If the rollers or track become stiff, apply a small amount of silicone-based lubricant to the moving parts. Avoid oil-based lubricants as they can attract dust.
