humidity are maintained within a specific range.
 Type I display refrigerators are intended for use in an
area where environmental conditions are controlled
and maintained so that the ambient temperature does
not exceed 75 °F (24 °C) and 55% maximum humidity.
 Type II display refrigerators are intended for use in an
area where environmental conditions are controlled and
maintained so that the ambient temperature does not
exceed 80 °F (27 °C) and 55% maximum humidity.
 If unsure if your unit is Type I or II, see tag next to serial
label. See SERIAL LABEL LOCATION & INFORMATION
LISTED / TECH INFO & SERVICE section in this

4. 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).
5. 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.
6. 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 are 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.
7. 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
