(6) PRIOR TO UNPACKING EQUIPMENT!
Inspect for shipping damage.
You are responsible for filing all freight claims with the delivering truck line. Inspect
all cartons and crates for damage as soon as they arrive. If damage is noted to
shipping crates, cartons, or if a shortage is found, note this on the bill of lading (all
copies) prior to signing.
If damage is discovered when the case is uncrated, immediately call the delivering
truck line and follow-up the call with a written report indicating concealed damage
to your shipment. Ask for an immediate inspection of your concealed damaged
item. Crating material must be retained to show the inspector from the truck line.

(7) INSTALLATION INSTRUCTIONS
7.1 LOCATING THE DISPLAY CASE
The case(s) should be located where it is not subjected to the direct rays of the sun,
heating ducts, grills, radiator, or ceiling fans, nor should it be located near open doors or
main door entrances. Also, avoid locations where there is excessive air movement or
air disturbances and avoid high humidity locations such as near cases with water
misting or fogging devices. Failure to locate this case as stated will reduce the
performance of your display and will affect temperature of interior of case and product.
If this case or cases are to be located against a wall there should be at least 6” between
the case and the wall to allow air circulation. Failure to give adequate space may cause
exterior surfaces to sweat.
7.2 REMOVING CASE FROM SHIPPING SKID
Be sure to leave shelf packaging material intact for this step.
First remove the base front and rear panels
REMOVE FRONT PANEL SCREW
THEN LIFT UP
ROTATE BOTTOM OF PANEL FORWARD
AND SLIDE OUT FROM BEHIND VALENCE
Two or more people should be involved in moving the unit from the pallet onto the
ground.
Remove the (4) 1/4” screws that secure the case to the skid. These screws are located
in the front and rear corners of the base rails. Base front and rear panels must be
removed to access these bolts.

E3980 VRSS 10
LAG BOLT
LOCATIONS
Once all the bolts are removed, slide the unit off the back of the shipping pallet, and tilt it
so the rear corner touches the ground. Then have someone move pallet out from under
the case and gently tilt the case forward until it touches the floor.
REMOVE CASE OFF OF FRONT OR BACK OF SKID ONLY
PULL SKID AWAY FROM CASE
AND GENTLY SET CASE ON FLOOR
Removing Packaging Material
Remove bubble wrap and packing material for all shelves and panel, brackets, etc.
If it is necessary to remove tape residue from plastic materials, use cleaning
compounds recommended in the cleaning section of this manual.
Lifting and Moving the Case
Caution:
Do not push or pull against the glass air deflector on front of
case. Doing so can cause the glass to break. Do not push or pull
on side glass or pull on base panel. Doing so will break glass or
pull out panel mounting screws. Care must be taken not to
damage the case when removing it from the skid or moving the
case.
