Case Description
Model
QM1LVC1
Description
Self-service, self-contained, prepared food display case with
curved glass and produced in 4 ft. length.
These cases are connected to a single condensing unit. Installation and Service
instructions are provided by the condensing unit manufacturer and are not part of this
manual.
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. A claim must be filed with the carrier by the consignee for all
damages.
Note: All claims for shortages must be within 10 days after receipt of shipment.
Page 4
Refrigerant
A variety of refrigerants can be used in the Kysor//Warren cases provided the
correct expansion valve is equipped with the case when ordered (i.e., R–404A
required for the end user requires specifying the correct expansion valve for R–
404A refrigerant when the order is placed). 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.
Condensing Unit
The condensing unit is not intended to be removed from the case except in the event a
compressor must be replaced. To remove the condensing unit, disconnect the flare
suction/liquid connections on the base valves at the right front of the case.
CAUTION: Before attempting to remove the condensing unit, be sure that all
electrical power to the case has been turned off. Also, caution should be used when
releasing pressure on the refrigerant system.
NOTE: The refrigerant charge for this case is very critical. If the case should need
to be recharged, an accurate charging device must be used. No refrigerant should be
released into the atmosphere. It must be reclaimed. There are several different refrigerant
configurations to these units. Refer to Case Data for detail.
CAUTION: During installation and service of this equipment, precautions should
be taken to prevent loss of refrigerant to the atmosphere.

Case Installation
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.
Caution: To prevent condensation on the end panels of cases, a minimum of 6.0
inches between walls or other cases is required for air flow. If 6.0 inches is not possible,
then the space between the cases must be completely filled and sealed or an updraft fan
kit must be installed to provide air circulation through the space.
3. Ensure floor loading will support the case and the case contents.
4. Ensure proper AC power is available. Refer to case AC input requirements located in
the electrical connections section of this manual.
5. 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. Ensure the evaporator cover is installed correctly with the deck pans installed.
Page 8
2. 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 Case
1. Ensure all preparation for installation, as outlined in the above paragraphs,
have been fully complied with and are complete.
2. 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.
Electrical Connections – General
An electrical box is provided with each refrigerator for wiring your fan, anti-sweat
heaters, and light circuits. This is an approved method by the Underwriters’ Laboratories;
however, field wiring must be in accordance with local and national electrical codes.
All field connections are made in the electrical box. Make sure that proper voltage is
supplied to your refrigerator. Check refrigerator nameplate for the required voltage for
fans, anti-sweat heaters, lights and defrost heaters. ALL REFRIGERATORS MUST BE
GROUNDED.
The Recommended Control Settings in the Case Data shows the electrical ratings for
your case. This is the same information that appears on your refrigeration nameplate.
NOTE: Fan motors must operate continuously and panel must be marked
sufficiently to prevent the fan motors from being turned off accidentally.
When refrigerators are multiplexed, add the total of these amperage values
to determine wire size and circuit protection. Anti-condensate controllers
can be used to control the anti-condensate heater.
Page 9
WARNING! Ensure the Kickplate does not come in contact with the case
electrical wiring. Live electrical wiring that comes in contact with the case is a shock
hazard that may cause severe injury or death by electrocution.
WARNING! Always disconnect the electrical power at the main disconnect
when servicing or replacing any electrical component. This includes, but is not
limited to, such items as fans, heaters, thermostats and light bulbs. Failure to
disconnect the electrical power may result in personal injury or death.
Electrical Termination
All electrical connections are
made in the control box located
in the base of the case.

Expansion Valve and Superheat
Caution: During service of this equipment, precautions should be taken to prevent
loss of refrigerant to the atmosphere. Always install the expansion valve stem cap after
making valve adjustments.
The expansion valve furnished with your case has been sized for maximum coil
efficiency. To adjust superheat perform the following:
1. Place a thermocouple near the expansion valve bulb. Read the suction line pressure as
near coil as possible. (If at the condensing case, estimate suction line loss at 2 PSIG).
2. Convert coil suction pressure to temperature. The difference between coil temperature
and the thermocouple temperature is superheat. (Use average superheat when expansion
valve is hunting).
3. Do not set superheat until cases have pulled down to operating temperature and never
open or close the valve over ¼ turn between adjustments and allow 10 minutes or more
between adjustments.
4. Superheat should be set to 6-8°F.
5. After the initial setting, the superheat should be rechecked when product is stocked and at
desired temperature.
EXAMPLE: R-404
25 deg suction temperature
- 17 deg suction press. Converted to temp
= 8 deg SUPERHEAT
Page 16
Operation
Loading
Merchandise should not be placed in the fixture until all controls have been adjusted and
the case is at the proper temperature. AT NO TIME SHOULD THE CASE BE
STOCKED BEYOND THE LOAD LINE.
All cases have load limit line markings.
Product must be kept within the load
limit line for cases to function properly.
Do not place product in cases until it is at proper operating temperature. Air discharge
and return flues must remain open and free of debris or obstruction at all times to provide
proper refrigeration and air current performance. Do not allow any product, signs, debris,
etc. to block these grilles. Do not use any non-approved shelving, display racks or any
accessory that could hamper air current performance.
Page 17
Warning! Do not walk on top of the cases! This could result in damage to the
case and serious personal injury could occur. These cases are not designed to support
excessive external weight. Do not use top of cases for storage.
Normal Operation
1. Off-Cycle Defrost is standard on these models and the fans run continuously.
Cleaning
As a general rule, always use mild soap and water to wipe the case down. Special
precautions must be taken when cleaning some components of the case.
Exterior surfaces should be cleaned with warm water and mild soap to protect and
maintain the finish. Do not use cleaners containing abrasive materials or ammonia,
which will scratch or dull the finish. The waste outlet should be flushed with water
following each cleaning.
Interior surfaces may be cleaned with most mild soap formulas, ammonia based cleaners
and sanitizing solutions with no harm to the surface.
WARNING! Always shut power off during the cleaning process. Cleaning
the case with electrical power applied is a shock hazard that may cause serious
injury or death.
WARNING! DO NOT USE HOT water on COLD glass surfaces. This could
cause the glass to shatter and could result in personal injury. Glass fronts and ends
should be warm before applying hot water.
Caution: The following could damage the case:
Do not use solvent, oil or acidic-based cleaners on any interior surfaces as the surface
may become damaged.
Do not use abrasive cleaners and scouring pads as these will mar the finish.
Never introduce water into the case faster than the waste outlet can release it.
DO NOT USE STEAM OR HIGH PRESSURE SYSTEMS TO CLEAN THE CASE AS
SEALS MAY BE BROKEN WHICH WILL CAUSE THE CASE TO LEAK.
Condensing Units
Follow the previous general cleaning of the interior and exterior parts with the exception
of DO NOT USE WATER HOSE to clean evaporator or tub of the case.
Page 18
Caution: Condensing units should have at least 18” clearance from any wall or
other obstruction in order to operate properly.
WARNING! Always shut power off at the main breaker during the cleaning
process. Cleaning the case or condensing unit with electrical power applied is a
shock hazard that may cause serious injury or death.
Caution: DO NOT FLUSH WITH WATER. This case is not connected to a
drain system and has its own evaporating pan with limited capacity.
Condensing Units: Once a month
compressed air should be blown through
evaporator to clear any debris or dust –
opposite to direct normal air flow.
Caution: Care should be taken
with compressed air. Debris and dust may
be blown into eyes.
Note: Do not stack anything that may block airflow in front of louvers or rear of
case. Self-contained cases draw air from back to front and blocking this airflow will
cause case to overheat and shut down.
Honeycomb Assembly
Honeycomb should be cleaned every 6-8 months, depending on store conditions. The
honeycomb may be cleaned with a vacuum cleaner or removed to be washed with soap
and water. The honeycomb must be completely dry before returning it to the case.
