How do you install the Trane FLRQB5AH23M11?

BOTTOM MOUNT INSTALLATION

  1. Rotate the two quarter turn latches on the access door to remove the access door from the enclosure and set it aside. Remove the filter and set aside until the enclosure is installed.
  2. Position the furnace/air handler on a protective pad on the floor with the bottom of the furnace/air handler in the up position.
  3. Install the self-adhesive gasket material onto the flange of the discharge-air side of the filter enclosure.
  4. Position the Trane FLRQB5AH23M11 filter enclosure on the bottom of the unit with the gasket against the unit. Align the rear of the enclosure with the rear of the unit and the two sides of the enclosure with the sides of the unit. The front of the enclosure will NOT align flush with the front of the unit.
  5. Check that the front of the filter enclosure is facing the front of the unit.
  6. Securely attach the filter enclosure to the unit using the heavy-duty self-tapping sheet metal screws. Recommended screw spec: #12-14, 1/2” length (3/8” if only two metal thickness), hex washer head, slotted drive, Type AB.

SIDE MOUNT INSTALLATION

  1. Rotate the two quarter turn latches on the access door to remove the access door from the enclosure and set it aside. Remove the Trane FLRQB5AH23M11 filter, and set aside until the enclosure is installed.
  2. Lay the furnace on a protective pad on the floor with the surface on which the filter enclosure will be installed in the up position.
  3. Align the rear of the filter enclosure flush with the rear of the furnace. Align the bottom of the filter enclosure 1/4 inch above the bottom of the furnace. Mark the inside opening of the filter enclosure using the inside edge of the mounting flange as a guide. Move the enclosure and cut the opening.
  4. Install the self-adhesive gasket material onto the flange of the discharge-air side of the filter enclosure.
  5. Position the filter, with the gasket against the furnace, over the furnace enclosure opening cut previously in step 3.
  6. Check that the front of the Trane FLRQB5AH23M11 filter is facing the front of the furnace.
  7. Securely attach the filter to the furnace using the heavy-duty self-tapping sheet metal screws. Recommended screw spec: #12-14, 1/2” length (3/8” if only two metal thickness), hex washer head, slotted drive, Type AB.
  8. Seal all joints in the return air system to prevent dust from entering the airstream.

As I found out just recently after having new ducts put in, it prevents dust and debris from clogging the AC unit. It definitely improves air quality.

I almost did not by the filter because your web site did not reveal the same deminision that I required. To be specific, the web page did list the 1/4 inch on the second and third Deminison. My Trane unit calls for that. The filter you send had the correct deminsion.

Great filters but one was damaged a little bit in shipping. The shipping box should be a little bit heavier material. I will order again when the time comes.
