QILG –06, 08, 12
Frozen Food / Ice Cream Island Case with glass front, 6 ft., 8 ft or 12
ft. lengths; offered with electric, off-cycle or hot gas defrost
Receiving/Shipping Damage/Lost Items
All equipment should be examined for shipping damage before and during unloading. If there is any
damage, the carrier should be notified immediately and an inspection requested. The delivery receipt must
be noted that the equipment was received damaged. If damage is of a concealed nature, you must contact
the carrier within three (3) days following delivery. The consignee must file a claim with the carrier.
NOTE: All claims for shortages must be within 10 days after receipt of shipment.
The Kysor/Warren case is designed to provide years of trouble free service.
Kysor/Warren Frozen Food / Ice Cream Cases are designed to
merchandise frozen food products. These cases should be installed and
operated according to the instructions contained in this manual to insure
proper performance. They are designed for display of products in an air-
conditioned store where temperature and humidity are maintained at a
maximum of 75% dry-bulb temperatures and 55% relative humidity.

6
Refrigerant
A variety of refrigerants can be used in the Kysor/Warren cases. Refrigerant type needs to be specified
during case order so correct expansion valve will be equipped with the case (i.e., R–404A expansion
valve required when the end user specifies R-404A refrigerant). Multiple expansion valves are available,
depending on end user refrigerant requirements. Expansion valves are supplied for the refrigerant
specified on the original sales order.
In addition, cases can be modified in the field to allow changing the type of refrigerant used. This requires
changing the expansion valve and distributor orifice that is currently equipped in the case. Contact your
Kysor/Warren Service Representative for additional information.
NOTE: Refer to Case Data Control Settings for refrigeration requirements.

NOTE: All the BTU requirements shown in the case data are for use on parallel systems
only. A minimum of 8% excess capacity should be added to all conventional single compressor
condensing units.
NOTE: The air current is very important to the performance of these cases. The load
limit line (see load case selection) is the indicator of the inside edge of the air current and at no
time should product, signs, debris, etc. interfere with air current.
NOTE: All electrical data based on 115V and unlighted shelves. For lighted shelves, add 0.25
amps per shelf.
NOTE: For sizing conventional/ individual condensing units, add 8% to BTU Load.
NOTE: Temperature is measured in discharge air. Defrost frequency is at design conditions. Higher
temperature or humidity may require more defrost and longer fail-safes. These cases are not designed to
operate environments where the ambient temperature is greater than 75ºF and the relative humidity is
greater than 55%. Off-cycle defrost is the recommended defrost for all Q case models. Electric defrost
and hot gas defrost are available for installations requiring a positive defrost.
CAUTION: Failure to maintain maximum design conditions may result in operational issues such
as: increased BTU load, high product temperature, coil icing, product frosting, and external sweating.
CAUTION: Failure to properly install electrical wiring and control wiring as per wiring
diagram(s), defrost settings, and temperature set-points may result in operational issues such as:
increased BTU load, high product temperature, coil icing, product frosting, and external sweating.
Case Installation
These display cases may be installed individually or in a continuous lineup consisting of several 4’, 8’
and 12’ sections using a joint kit.
Preparation
Prepare the installation area as follows:
1. Clean area where case is to be installed.
2. Verify installation area is at least 15 feet from any outside entrances or heating and cooling
outlets.
3. Verify at least 2 feet of distance between hot and cold cases.
CAUTION: To prevent condensation on the end panels of cases, a minimum of 6.0 inches
between walls or other cases is required for airflow. If 6.0 inches is not possible, then the space between

11
the cases must be completely filled and sealed or an updraft fan kit must be installed to provide air
circulation through the space.
4. Ensure floor loading will support the case and the case contents.
5. Ensure proper AC power is available. Refer to case AC input requirements located in the
electrical connections section of this manual.
6. Ensure location will allow connection to drain lines and the drain line, when installed, will meet
the recommendations as set forth in the refrigeration piping and dehydration section of this
manual.
7. Ensure expansion valve in case is the proper valve for the type of refrigerant used at the
installation site.
Installation
The following instructions are provided for unpacking, moving, loading, and lifting the case prior to
installation.
NOTE: READ ALL INSTRUCTIONS CAREFULLY BEFORE BEGINNING INSTALLATION.
Unpacking
1. Remove all shipping tape from lamps and ensure that all lamp ends are snapped in place.
CAUTION: When removing the strapping in the following procedure, as the shelves are very
heavy and could fall causing personal injury or equipment damage.
2. Ensure the evaporator cover is installed correctly with the deck pans installed.
3. Move the case into position, install, adjust superheat, and perform the operational checkout
procedures following the instructions within this manual.
CAUTION: Be careful not to damage the factory-installed end while moving the case. Use
the case lift points on the case to move it to the proper location.
Installing First Case
1. Ensure all preparation for installation, as outlined in the above paragraphs, have been fully
complied with and are complete.
2. If multiple cases are to be installed, find the highest area of the floor to place the first case.
3. Allow a minimum of 6 inches between the rear of the case and the store walls and/or other cases.
This space reduces the possibility of condensation problems. It may be necessary to provide
forced air ventilation in some installations.
4. All cases must be located on a firmly based floor and leveled within plus or minus 1/16 inch.
5. Use shims provided to support and level the entire length of your case(s). All rails of the case
must be properly shimmed and in contact with the floor. Cases with shims on the ends must
also have shims in the middle no more than 4 ft. apart. All legs of the case must be properly
adjusted and in contact with the floor.
6. If multiple cases are to be installed, refer to the floor plan and install the first case in the lineup by
snapping a chalk line where the front and rear of the cases are to be located.
7. Continue the chalk line if multiple cases are to be installed. The first case is typically the
case that is at the highest area on the floor.

8. Connect water drain line. Reference waste outlet (drip pipe) description and location
procedure.
9. Connect input AC power. Reference the electrical installation procedure later in this manual.
10. Connect refrigerant lines. Reference the procedure later in this manual.
11. Install all ends, caps, and trim per the applicable instructions contained in this manual.
12. Remove shipping tape on fluorescent lamps (if applicable) and remove all other shipping
material.
13. Refer to the operational start up procedures later in this manual. If multiple cases are to be
installed, refer to the following paragraph for installing subsequent cases.
Installing Subsequent Cases
If additional cases are to be installed, follow the same procedures as described in the installing first case
procedure (above), in addition to the following:
1. Move cases as near their permanent location as possible before removing shipping braces, skids
or rollers.
NOTE: All cases are factory numbered with lineup and position numbers. Make sure that cases are
installed in order (lineup sticker found on the fan plenum or door and on the back panel of the case).
2. Remove skids and shipping braces.
3. Ensure all case expansion valves are correct.
4. Do not install electrical, drain lines, or refrigerant lines until all the cases have been set/placed
into position and properly leveled.
5. Do not install case trim, ends, or caps until all cases have been set into position and properly
positioned and leveled.
6. Before lining up cases use the front and rear edges as a baseline to inspect refrigeration lines,
electrical connections and controls, and to insure cases are in proper lineup and are in proper
sequence.
7. Remove shipping tape on fluorescent lamps (if applicable) and remove all other shipping
material. Follow all joining instructions listed below to connect cases in a lineup.
Joining Instructions
Two or more cases of like models can be joined together to form a continuous lineup. Before lining up
cases, inspect refrigeration lines, electrical connections and controls to insure cases are in the proper
lineup and sequence. Reference and become familiar with the below figure, then join the cases using the
instructions that follow.
Lineup Bolt Holes on the Side of the Cases - See Caulking Diagram Below

13
1. Apply foam insulation tape and caulking around the side of the case as shown in the diagram
above.
2. Remove access covers over lineup holes and insert the small lineup bolts (see previous diagram)
in the end frame in the bolthole pattern. Place the special T-nut washer on the 3/8" machine
bolt with the hollow section away from the bolt head. Tighten the 3/8" bolts with nut washer
into the T-nuts alternately until cases are pulled up tight and the joint is completely sealed.
(Reasonable care should be exercised in this procedure to prevent end frame distortion.)
Assist pulling case up tight by bumping from opposite end of case or by using pry bar.
3. Inspect joint for proper air and watertight seal inside and outside the case.
4. Replace lineup access cover plugs and plates.
5. Move cases as close together as possible and level by using the shims provided (same as original
case). Use shelf standard struts for alignment to be sure cases are level.
CASES MUST BE LEVELED FROM FRONT TO BACK END-TO-END AND SUPPORTED
CONTINUOUSLY AS NEEDED WITH SHIMS.

Glass Cap Rail End Trim Installation - Glass Models
Rear Cap Joint Trim Installation
After the display cases are properly joined and sealed, remove the screw cover from the rear cap of every
other case in the lineup and remove the screws from the rear cap. Rotate the rear cap forward (the
alignment pins will hold it in place) and position the trim as shown in the illustration. Slide the trim
across the case joint under the rear cap of the adjoining case about half the width of the trim.
Rotate the rear cap back into place over the trim and secure the rear cap and screw cover. Repeat this
procedure for each case joint.

18
Bumper, Rub Rail Cap, and Raceway Cover Installation
1” Bumper
Install the two-foot length of 1” bumper to the left hand end of the first case in the lineup. To install the
bumper, hook the lower edge of the bumper to the aluminum retainer. Rotate the bumper up and snap the
top edge onto the retainer. Install this part as close to the case flat end panel as possible.
Install the additional case length 1” bumper parts, crossing over the joint of the cases in the lineup and
trimming the last piece to fit the last case in the lineup.
Rub Rail Cap
Install the four foot rub rail cap to the left hand of the first case in the lineup. To install the rub rail cap
hook the lower edge of the cap to the aluminum front rail just above the 1” bumper. On non-glass models,
rotate the cap toward the case and snap the cap onto the back hook of the aluminum front rail. For glass
models, rotate the cap toward the case and snap the cap onto the top hook of the aluminum rail. Install this
part as close to the case flat end panel as possible.

joint of the cases in the lineup and overlapping each part where provided. Trim the last part to fit the last
case in the lineup.

19
NOTE: If a mutual end is used in a lineup, the proper additional pieces of trim should be used.
Waste Outlet (Drip Pipe) Description and Location
These cases are equipped with 1 ½" M-NPT waste outlet connection that terminates in the center of the
refrigerator below the insulated bottom. The water seal trap is shipped unattached for field installation.
NOTE: Improperly installed drip pipes can seriously effect the operation of this case and result in
increased maintenance costs. Listed below are some general rules for drip pipe installation:
•Never use a double water seal.
•Never use a pipe smaller than the size pipe or water seal supplied with the case.
•Always provide as much fall as possible in drip pipe. (1" fall for each 4' of drip pipe.)
•Avoid long runs in drip pipe, which make it impossible to provide maximum fall in pipe.
•Provide a drip space between drip pipe and floor drain or sewer connection.

20
•Do not allow drip pipe to come in contact with un-insulated suction lines, which will
cause the condensation from your case to freeze.
Drain Strainer
NOTE: Not all of our cases have drain strainers. This information applies only to the cases
equipped with the strainers.
•Purpose: Keep debris or any foreign objects from entering the PVC drain, which could cause
blockage.
•Installation: Insert into drain until drain strainer stops - it will not be flush. The strainer will
exceed the hub by 1”.
•DO NOT flatten drain strainer.
NOTE: 1” Drain Pipe
Electrical Connections - General
Cases are standard with one row of high output lamps. Ballasts are located in the raceway. If lighted
shelves are supplied, ballasts for each shelf will be located under each shelf in the electrical raceway. See
wiring diagram for layout.
