È HOW TO REPLACE THE T-SEAL
The T-Seal (used in Dryers and Conditioners) must be maintained in good working condition to maintain the
proper direction of air flow and ensure drying efficiency. A drop in efficiency, particularly where outlet tempera-
tures are prematurely achieved, is evidence of a leaking T-Seal. If this condition occurs, inspect the T-Seal tension
bracket. If no tension exists, it is likely the T-Seal has broken and must be replaced. This procedure requires two
people.
CRUSHING AND ENTANGLEMENT HAZARD—Rotating machinery can entangle
and crush body parts. Lock OFF and tag out power at the wall disconnect for
the Dryer or Conditioner.
Ê Removing the Old T-Seal
1. Remove the side access panels to gain access to the T-Seal and bracket. See FIGURE 1.
2. Release the tension on the bracket (if any tension exists) by loosening the hex nuts on the tension rod. See “T-SEAL
ASSEMBLY . . .” in this section.
3. Disassemble the tension bracket from the T-Seal. See “T-SEAL ASSEMBLY . . . ”
4. Thread a piece of strong, flexible wire through the holes in the end of the T-Seal, as shown in FIGURE 2, and remove
the T-Seal from the J-ring by pulling the wire while another person hand turns the basket via the large cog belt pulley.
NOTE: Work the old T-Seal out gently while hand turning the basket to avoid breaking the T-Seal any more than it
already is. Never turn the basket under motor power.
Ê Installing the New T-Seal
1. Check T-Seal mounting holes for fit and alignment. Studs should fit smoothly.
2. To minimize T-Seal stress and ease the threading process, place the new T-Seal atop the basket shroud. This will allow
the new T-Seal to be fed easily down into the lower basket “J-ring” area.
3. Thread a piece of strong, flexible wire
through two holes in the end of the T-
Seal to be fed into the “J ring.” Feed
this end of the T-Seal down the side of
the basket. Feed the wire ends through
holes in the perforated basket. Tie the
wire ends together inside the basket,
then start the T-Seal into the left J-ring.
NOTE: If the T-Seal becomes caught
while installing, do not force the cog belt.
Simply reverse the direction of the belt until
the T-Seal is freed, then continue feeding
the T-Seal through.
4. Referring to “T-SEAL ASSEMBLY. . .,”
reattach the left side stud and yoke assem-
bly to the free end of the T-Seal. Also in-
stall the spring tension rod, the left
side rod adjustment components, and
hex nuts. Thread these hex nuts completely down the threaded portion of the spring tension rod.
NOTE: Step 4 could be done after the T-Seal has been completely fed through the J-ring channel, but it is easier to
do while the end of the T-Seal is easily accessible.
5. With one person feeding the T-Seal into the J-ring and another person slowly hand turning the basket via the large cog
belt, continue feeding the new T-Seal into the left J-ring as shown in FIGURE 3 until the entire T-Seal is fed through.
6. Remove the wire.
7. Install the remaining right side stud and yoke, then finish installing the right side tension rod components. Thread the
right side hex nuts completely down the threaded portion of the spring tension rod.
8. Finish by installing the T-Seal retaining bracket, adjust the bracket for 1/8" - 3/16" (.31-.47 cm) clearance between the
top edge of T-seal and the bottom of basket. See “T-SEAL ASSEMBLY . . . ”
To verify that the T-Seal is properly installed, re-establish dryer or conditioner power and operate manually (as
explained in the programming, operating and troubleshooting manual) to turn the cylinder clockwise and coun-
terclockwise. Observe the T-Seal to be sure tension is maintained as the cylinder rotates. If any adjustments are
required, lock OFF and tag out power before proceeding.
