(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.

E3980 VRSS 11
7.3 SINGLE CASE INSTALLATION (STAND ALONE UNITS)
Leveling the Case
It is important that the case is level. This will allow for proper drainage of condensate
water from evaporator coil. Once the case is placed in final location the case must be
level for proper drainage of defrost water to the condensate pump. A wrench is included
to aid in adjusting leg levelers.
Check the left-to-right level of the case along front of plastic air deflector retainer.
Check the front-to-rear level of the case along the interior ends of the case.
LEVEL CASE USING THESE SURFACES
Adjust the (4) outside leg levelers as needed to level the case in each direction.
NOTE: If necessary, use a wood or plastic shim under each leg leveler to avoid
scratching the tile floor.
Sealing Unit to The Floor
After the unit is positioned and the leg levelers are turned out, the unit needs to be
sealed to the floor for NSF approved installation.

7.4.2 Join units with glass divider, or join refrigerated to non-refrigerated
For this joining configuration, one unit will come with a lower end panel
preinstalled with glass. Five bolt holes will be exposed on the outside of this
panel and are the locations that will be used to join the units together. This kit
also comes with top and rear exterior trim, but no interior trim.
1. Remove all Shelves, display deck, interior back panel(s), exterior back(s), front
and rear base panel, and loosen honeycomb (see cleaning section for
honeycomb removal) material on the unfinished end to expose the holes used to
bolt units together.
2. Position the right or left most unit in the desired position for the lineup to start,
and level this case.
3. Push the 2nd case next to the 1st and line them up as closely as possible.
4. Adjust the leveling legs of the 2nd case until the bolt holes align with the mating
holes in the joining case.

(8) SHELF INSTALLATION AND REMOVAL
8.1 SHELF BRACKETS AND SUPPORTS
NOTICE: Improper shelf configuration will cause
performance issues
VRSS 78in tall units have two different shelf depths. The lower two
shelves are longer, the upper two to three shelves are shorter. The
longer shelves must installed as the lowest shelves or the unit’s air
curtain will be disrupted and the unit will not maintain product
temperature.
Shelves are pre-installed in the factory. To change shelf positions, remove the shelf,
then shelf support, then brackets. Relocate the brackets to the desired shelf position.
The left bracket and right bracket must be at the same height. This can be ensured by
counting the position of the notch in the shelf standard. If you have shelf lights, the wire
running to the light must be unplugged prior to moving the shelves. Note how the wire is
run through the shelf support, and shelf.

The diagram below illustrates how to straighten or angle the shelves. To angle the
bracket, be sure to have the top hook of the bracket in its slot and to pull up while
rotating down to the most extreme downward position. To angle the shelf, first angle
both brackets, and install the shelf as normal.

Indicates temperature unit of measure.
Powering on control
To turn refrigeration control power on, press and hold “ ” for approx. three seconds.
When the control powers on, the display will read the cabinet probe temperature. The
compressor and condenser fan run indicators ( & ) will illuminate on the display,
meaning that the compressor and condenser fan are running. (Note: the control may
already be in the on mode when shipped from factory).
To turn refrigeration control power to off, press and hold “ ” for approx. three
seconds. When the control powers off the display will read “OFF”. When refrigeration
control is in the off-mode cabinet lights and evaporator fans will still operate, but the
compressor will not turn on causing the case to gradually reach room temperature.
Adjusting the set point
The set point is what determines how cold the display case will hold food and beverage.
To adjust the set point press the “ ” button. Then press “ ” button to increase the set
point number (colder) or press the “ ” button to decrease the set point number
(warmer). There are nine (9) available set points numbers, the higher the number of the
set point, the colder the display case will run, with setting “9” being the coldest and
setting “1” being the warmest. Once you have chosen your desired setting press the “
” button again to confirm your choice. The control cutout temperature for the selected
setpoint will briefly be displayed if the setpoint was changed.
Entering manual defrost mode
The control is programmed to automatically initiate a defrost by two different methods,
involving time and temperature, as outlined in the “Defrost Cycle” section (Pg.) of
“ELECTRONIC CONTROL PARAMETERS AND EXPLANATION OF OPERATION.”
While it is uncommon that the automatic defrost cycles would insufficiently defrost the
case, a Manual Defrost mode is available if this situation arises.
Note: The control will not allow the initiation of a manual defrost within 30 minutes of
completion of another defrost cycle, manual or automatic.
To initiate a manual defrost press and hold the “ ” button approx. three seconds. The
defrost is initiated when the defrost mode indicator illuminates on the display. The
control display will then return to reading the probe temperature. When the defrost
mode indicator turns off the defrost is complete and the compressor will turn back on
automatically and the compressor and condenser fan indicator will be shown ( & ).
