4. Verify the appliance is level. See "Level the Appliance" (pg. 17).
5. On the low end of the appliance, loosen the castor bolt
enough to slide provided castor shims between the castor
bearing and the bottom rail of the appliance. See fig. 9.
6. Install the desired number of shims. See fig. 9.
• If more than one shim is used, be sure shim slots are offset.
See fig. 10.
• DO NOT use more than four (4) shims on a castor.
• Be sure each shim touches the castor stem.

Level the Appliance
Tipping hazard! ALWAYS
fully contact the floor after leveling the appliance.
Proper leveling of your TRUE appliance is critical to operating
success (for non-mobile appliances). Leveling impacts effective
condensate removal and door operation.
See "Leveling Screw, Leg or Castor Installation" (pg. 14) for level
adjustment and shimming information.
Procedure
Position the appliance in its final installation location. Then, level
the appliance front-to-back and side-to-side. See fig. 1.
1. Position the level on the inside floor of the appliance near the
doors (level parallel to appliance front). Level the appliance.
2. Position the level at the inside rear of the appliance (level
parallel to appliance back). Level the appliance.
3. Position the level on the left and right inside floor (level parallel
to appliance sides). Level the appliance.
Fig. 1. Measure the level along the perimeter of the interior floor.

Seal the Appliance to the Floor
WARNING!
Asphalt floors are susceptible to chemicals. TRUE
verify center leveling screws
recommends installing a layer of tape between the
asphalt and the sealant to protect the floor.
The following procedure describes sealing a non-mobile appliance
to the floor for NSF standards. This may not be required for your
application.
Procedure
1. Position the appliance in its final installation location. Be sure
to leave adequate clearance between the back and sides per
"Clearances" (pg. 8) to ensure proper ventilation.
2. Level the appliance front-to-back and side-to-side. See
"Level the Appliance" (pg. 17).
3. Draw an outline of the appliance base on the floor.
4. Raise and block the front side of the appliance.
5. Apply a bead of NSF-approved sealant (see list below) to the
floor, 1/2" (13 mm) inside the front part of the outline drawn in
step 3. The bead of sealant must be heavy enough to seal the
entire appliance surface when the appliance is lowered on top
of the sealant.
6. Raise and block the rear of the appliance.
7. Apply sealant to the floor on the other three sides, as outlined
in step 5.
8. Examine the appliance to ensure that it is sealed to the floor
around the entire perimeter.
