Receiving Case
Upon receiving your new Hussmann Case all equipment
should be thoroughly examined for shipping damage
before and during unloading. This equipment has been
carefully inspected at our factory. Any claim for loss or
damage must be made to the carrier. The carrier will
provide any necessary inspection reports/ or claim form.
If there is obvious loss or damage, it must be noted on the
freight bill or express receipt and signed by the carrier’s
agent; otherwise carrier may refuse claim.
Snapping Chalk Lines
Preparepermanentpositioningbymarkingoorswith
Chalk snap lines where cases are to be located. Chalk
lines are to run along the base or legs of cases.

6
Placement
Important: See lifting instructions to properly lift case when
being placed on dollies or permanent location. (See page
7 for Lifting Instructions.)
Leaveallhardwareandttingsinplaceuntilcaseis
located at or near its preferred location. Using a J-Bar
lift the case from the 2x4 boards and placing dollies
underneath each Base Leg, proceed to moving the case to
its designated location if not done so already.
IF APPLICABLE
(NOT ALL CASES CONTAIN LEG BRACES)
The Illustration Below demonstrates perfect placement of a
dollie per 1 side for both Base Legs of the merchandiser.
IF APPLICABLE
(NOT ALL CASES
CARRY LEG BRACES)
Movethextureascloseaspossibletoitspermanent
location and then remove all packaging and
preparetoremoveo󰀨Skid.Removeallseparately
packed accessories such as kits, and panels.
Check for damage before discarding packaging.
Installation (cont’d)
Remove screws as well as fastened plates bolted to each
2x4 board at each base leg.
Remove fastened plates only upper Brace Legs are to
remain fastened onto case.
Fastened plate
Once the fastened plates are removed a J-Bar can be
used to lift at each end of the Leg Braces to remove the
below 2x4 boards.

Lifting and Transport Instructions
1. The VR3 can be lifted by a forklift at typical lifting
points.
2. Ensure lower body panels are removed before lifting
with a forklift. Serious damage will occur if the body
panels are not removed.
3. Make sure that fork spacing and width will not damage
drain or come in contact with piping, or electrical lines
4. Be sure that the forks are long enough to support
beyond the center of the case but not damage near
components. Check for proper balance before moving.
A minimum fork length of 36” is recommended for 68”
wide cases
5. The VR3 merchandiser can be raised at one end
underneath the deck with a forklift to allow the
placement of rollers or dollies.
6. Evenly support the entire base structure on rollers or
dollies before attempting to move. Each Base Leg
must have its own dollie to properly support the case.
Lifting Points are typical and dependent upon size of case
andrefrigerationapplication,drainagecongurationswill
call for altercations in Lifting Zones.
Belowarethefollowingdrainagecongurationsandlifting

Installation (cont’d)
Rear Body Panel Install
1. Align clips of rear panel to Base Legs of case
2. Secure top and bottom clips of rear panel to Base
Legs as shown below.
Lower Body Panel Install
No tools will be needed to install body panels.
To begin Bottom panel assembly place the front panel
along in front of the case and align the base legs just
underneath the lower sections of the case. Snap in spring
clips to the base legs of the case.

Levelling Adjustment
Position the case at the highest point. Set a long
magnetized level (4ft [1220 mm] or more) on either
underneath the deck or on top of the case. Ensure to level
case from front to back and side to side.
Level
(4 ft[1220mm])
Leg Adjustment
Adjust the legs at each corner of the case to level out any
discrepancies in order to optimize case performance and
proper drainage.
Note:Toavoidremovingconcreteooring,beginlineup
levellingfromtheHighestpointofthestoreoor.
A wrench or pliers may be used to adjust each base leg.
Turning the base of each leg clockwise will raise the height
of the case.
Turning the base of each leg counterclockwise will lower
the height of the case.

Refrigeration
Refrigerant
The correct type of refrigerant will be stamped on each
merchandiser’s serial plate. The case refrigeration
piping is pressurized with a nitrogen holding
charge, leak tested and factory sealed. Before making
refrigeration hookups, depress universal line valve
(Schrader Valve) to ensure that coils have maintained
pressure during shipment. In the case pressure was not
maintained contact your Hussmann Service Tech for
further assistance.
SERIAL PLATE
LOCATION
CAUTION
Refrigeration lines are under pressure.
Refrigerant must be recovered before
attempting to make any connections.
Refrigerant piping
The refrigerant line connections are at the right hand end
of the case (as viewed from the front) beneath the display
pans. The merchandiser will beforehand ensure an earlier
cut hole through the pod to exit the merchandiser for the
refrigeration lines. After connections have been made,
make certain to seal this outlet thoroughly if not sealed
at factory already. Seal both the inside and outside. We
recommend using an expanding polyurethane foam
insulation.
Line Sizing
Refrigerant should be sized as shown on the refrigeration
legend that is furnished for the store or according to the
ASHRAE guidelines
Oil Traps
P-traps (oil traps) must be installed at the base of all
suction line vertical risers.
It is the contractor's responsibility to install
case(s) according to local construction and
health codes.
