INSTALLATION & OpERATION
1. Open the door to observe current door tension. A properly tensioned door
will close itself gently and not swing open.
2. Use a flathead screwdriver to turn the door tension screw ( See Figure 23 ).
Do not use power tools; a screwdriver allows for more control.
3. To increase tension, hold the door open 2 inches and turn the screw
counter-clockwise until the door begins to close. Once it closes, increase
tension by 2 more turns.
4. To decrease tension, turn the screw clockwise.
REMOVING A DOOR
1. Remove the top case trim and electrical raceway cover that covers the door
hinges.
2. Turn the door tension screw clockwise until the door does not close on its
own ( See Figure 23 ). This removes tension between the door and torque
adjuster so the door can be removed.
3. Disconnect the hold-open bracket from the bottom of the door ( See Figure
22 on page 16 ).
4. Crack open the door and add a wedge, such as a screwdriver. use a
needle-nose pliers to pinch the hinge pin while closing the door. This will
disconnect the door from the case ( See Figure 24 ). Note: The door is
heavy. Be prepared to catch the weight of the door.
a. Alternative: use a needle-nose pliers to pinch the hinge pin, and then
pull the top corner of the door away from the case. Note: The door is
heavy. Be prepared to catch the weight of the door.
5. Lift the door clear of the torque adjuster and set it down carefully. Note: For
safety, lift the door by the rails; do not lift by the handle.
INSTALLING A DOOR
1. Lift the door and set it into the torque adjuster. Swivel the door back and forth until you can feel that the door has dropped into the torque
adjuster. Note: The door is heavy. For safety, lift the door by the rails; do not lift by the handle.
2. Carefully open the door until it is perpendicular to the case, align the hinge pin, and then push the top of the door so the hinge pin clicks
into place ( See Figure 25 ). Note: Test whether the door is held securely by the hinge pin by pulling down on the door.
3. Attach the hold-open bracket between the bottom of the door and the bottom of the case ( See Figure 22 on page 16 ).
4. Turn the door tension screw counter-clockwise until the door gently closes
itself ( See Figure 23 ). Check for sag/sawtoothing.
REVERSING DOOR SWING
1. Remove the top case trim and electrical raceway cover that covers the door
hinges.
2. Remove the door from the display case. See "Removing a Door" on page
17 for a detailed description. Note: The door is heavy. For safety, lift
the door by the rails; do not lift by the handle.
3. Lift the door clear of the torque adjuster and lean it on its side, handle side
down. This makes it easier to access the wiring cover on the hinge side of
the door.
