VR1-D Lifting and Transport
Instructions
1. The VR1-D 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.
(Shipped loose from factory)
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
sup-port beyond the center of the case but not
dam-age near components. Check for proper
balance before moving. A minimum fork length
of 36” is recommended for 68” wide cases
VR1-D-8 Drain Location
1. The VR1-D merchandiser can be raised at one
end underneath the deck with a forklift or J-Bar if
forklift is not accessible to allow the placement of
rollers or dollies.
2. Evenly support the entire base structure on
rollers or dollies before attempting to move. Each
Base Leg must have its own dolly to properly
support the case.
Lifting Points are typical and dependent upon size of
case and refrigeration application, drainage
configurations will call for altercations in Lifting
Zones.
Below are the following drainage configurations and
lifting should be altered to the expected model.
8' Case
WARNING
Improper placement of forks may damage
drainage piping. Use a spotter when placing
forks. Make sure that piping will not be dam-
aged. Use J-Bars or Jacks if forks cannot be
used safely

location.
First remove Blocks and L Brackets around
the case from pallet.
Proceed by setting forklifts under specified loca-
tions as instructed in the Lifting Instructions. Be
careful not to damage drains or near
components when placing forks underneath
case. A spotter is mandatory to ensure no dam-
age is caused to the case. Lift case and replace
with dollies, place near or in permanent location.
Insert Forks
Underneath

Move the fixture as close as possible to its per-
manent location and then remove all packaging
and preparing to remove off Skid. Remove all
separately packed accessories such as kits, and
8
panels. Check for damage before discarding
packaging.
In the case a fork lift truck is not available follow
the demonstration below to properly lift case us-
ing a Johnson Bar (J-Bar) to place on dollies to
traffic from start point to placement area.
Place J-Bar underneath base of merchandiser to
gain leverage, once lifted place Dollie under-
neath first end and slowly lower onto dollie en-
suring merchandiser is placed on stable location.

Leveler Adjustment
(Channel-Style Legs)
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])

Note: To avoid removing concrete flooring,
begin line up levelling from the Highest point of
the store floor.
Shim The Case
Use shims at each corner of the case to level
out any discrepancies in order to optimize case
performance and proper drainage.
Note: Metal Shims are recommended for use to
eliminate any deterioration from shims over time.
Shim
NOTICE
Longer length cases may require shims
along the center portion of the case to
maintain proper case performance and
drainage.

Installation (cont’d)
Setting and Joining
The sectional construction of these models enable
them to be joined in line to give the effect of one
continuous display.
An alignment pin kit is supplied with every case and
must be used in alignment.
Leveling
IMPORTANT! IT IS IMPERATIVE THAT CASES
BE LEVELED FROM FRONT TO BACK AND
SIDE TO SIDE PRIOR TO JOINING. A LEVEL
CASE IS NECESSARY TO ENSURE PROPER
OPERATION, WATER DRAINAGE, GLASS
ALIGNMENT AND OPERATION OF THE HING-
ES SUPPORTING THE GLASS. LEVELING
THE CASE CORRECTLY WILL HELP TO
SOLVE MOST HINGE-RELATED ISSUES.
10

Installation (cont’d)
Setting
STEP 1. Using case blueprints, measure off and
mark on the floor the exact dimensions of where
the cases will sit. Snap chalk line for front and
back positions of base rail or pedestal. Mark the
location of each joint front and back. Find the
highest point throughout the lineup. FLOORS
ARE NORMALLY NOT LEVEL! Determine the
highest point of the floor; cases will be set off
this point. All cases in the entire lineup must be
brought up to the highest level of the case sitting
at the highest point in the lineup.
STEP 2. Set first case over the highest part of
the floor and adjust legs so that case is level.
STEP 3. Set second case within one foot (1’) of
the first case. Keep the supports along the length
of the case and far end of case. Level case to the
first using the instructions in step one.
ATTENTION
INSTALLER
It is the contractor’s responsibility to install
case(s) according to local construction and
health codes.
Do not use bolts to pull cases together.

Refrigeration
Refrigerant
The correct type of refrigerant will be stamped on
each merchandiser’s serial plate. The case
refrigeration piping is pressurized with a
nitro-gen holding charge, leak tested and
factory sealed. Before making refrigeration
hookups, depress universal line valve (Shraeder
Valve) to ensure that coils have maintained
pressure during shipment. If in the case pressure
was not maintained, contact your Hussmann
Service Technician for further assistance.
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 refrigera-
tion 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.
