INSTALLATION, CONT’D.: CASTER ADJUSTMENT / LOCK / UNLOCK / CASE REMOVAL FROM SKID
3. Caster Height: Raising and Lowering
 Raise or lower casters (to adjust case height) by
rotating casters’ vertical adjustment rings.
 Rotate vertical adjustment ring clockwise to lower
caster (and increase height of case).
 Rotate vertical adjustment ring counter-clockwise
to raise caster (and decrease height of case).
4. Caster Rolling Capability: Unlocking
 Important! Case is shipped with caster mechanisms
factory set at ON (locked) to prevent case from
rolling.
 Unlock casters by pressing OFF on the caster
mechanism.
 See illustration at right.
5. Carefully Remove Case From Skid
 Check that casters are lowered as far down as they
will go (as instructed in step #4).
 Use handles to carefully slide case to rear of Skid
(see illustration at right).
 Caution! 4 people may be required for this task!
 Carefully lower to floor (using ramp if available).
 Slide Skid from under case as required.
 Maintain support of case at all times or center
of gravity may cause case to fall.
 See illustration at right.
6. Casters: Locking
 After case is at desired position (and height), use level
to check that case is level and plumb.
 Readjust height as needed (as instructed in
step #4).
 Locking Height: After proper height (and
positioning) of case is attained, tighten the two
(2) set screws to lock each caster’s height in place.
 Locking Movement: Then, to prevent casters’ rolling
capability, lock casters by pressing ON atop the “ON”
and “OFF” lever mechanism (shown at right). Case
will now be secured at its new location.

PRODUCT PLACEMENT / AIRFLOW CONSIDERATION / LOAD LINES
 See illustration below.
 Caution! For discharged air to reach the return air
grille, you must not block front OR rear grilles with
product.
 Do not place product on front ledge of case.
3. Load Lines
 Load lines represent the limit that product can be
place (either horizontally or vertically) and/or
stacked in case.
 Keep product at or under load lines to assure that
heated airflow is properly cycled from air diffuser
through return air grille.
 Proper product placement will maintain
acceptable product temperature.
 See illustration below.
1. Product Placement
 Product can be placed on decking or steps
(risers) within the service display area.
 A wide range of product may be displayed.
2. Air Diffuser Grille & Return Air Grille
Considerations
 Proper airflow is critical to maintain proper
product temperature.
 Proper product placement will allow discharged
air to flow over (and around) product to the
return air grille (at case rear) AS WELL AS the
upper airflow circulation system. See illustration
below.
