Installation and Operation Manual

Introduction—General Information
This manual has been prepared for our customers and the personnel involved in installing and servicing our display
cases. Kysor Warren glass door reach-in cases are designed to provide years of trouble free service.
Our reach-in case line has been designed with a focus on things most important to your bottom line. Enhanced mer-
chandise visibility, best in class energy performance, and merchandising exibility have all merged in an attractive
design that ts seamlessly into your oor plan while saving energy costs. The F-series case line is available in low
temperature applications.
These cases should be installed and operated according to the instructions contained in this manual to ensure 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.
CAUTION: Failure to maintain maximum design conditions may result in operational issues such as the following: in-
creased BTUH load, high product temperature, coil icing, product frosting, and external sweating.
These models, with their unique design, offer the right combination of energy efciency, design versatility and econo-
my to meet your specic needs. Case models are available in standard depth or narrow depth, standard height or tall
height. The 5-series case line will accommodate 4, 5, or 6 levels of product display shelving in addition to the deck pan
level for greater merchandise visibility that grabs shoppers’ attention. Standard depth and narrow depth case models
will accommodate 27” and 22” maximum depth shelves, respectively.

Receiving/Shipping Damage/Lost Items
All equipment should be examined for shipping damage before and during unloading. If there is any damage, the car-
rier should be notied immediately and an inspection requested. The delivery receipt must be noted that the equip-
ment was received damaged. If damage is of a concealed nature, you must contact the carrier within three (3) days
following delivery. The consignee for all damages must le a claim with the carrier.
NOTE: All claims for shortages must be within 10 days after receipt of shipment.
Refrigerant
A variety of refrigerants can be used in Kysor Warren cases. The refrigerant to be used in the refrigeration system
should be provided at the time that the case is being ordered so that the correct distributor orice and expansion
valve can be factory installed in the case before it is shipped. Multiple brands and models of expansion valves are
available, depending on the end user’s refrigerant type being used. Distributors and expansion valves are carefully
selected and provided for the refrigerant type specied on the original sales order.
NOTE: Refer to Case Data Control Settings for refrigeration requirements.

Maximum Top Shelving Size Recommended:
Standard depth case models: 27” Narrow depth case models: 22”
NOTE: Maintaining the vertical air curtain exiting the discharge honeycomb grid very important to the performance of
this case. Load limit line labels are applied to the inside of the ends installed on the case. The load limit line (see oper-
ation section) is the indicator of the inside edge of the air current and at no time should shelving, product, signs, debris,
etc., extend into the air curtain and disrupt airow exiting the discharge honeycomb on the inside top of the case.
NOTE: Temperature is measured in discharge air. Defrost frequency is at design conditions. Higher temperature or hu-
midity may require more defrost and longer fail-safes. These cases are not designed to operate in environments where
the ambient temperature is greater than 75oF and the relative humidity is greater than 55%.
NOTE: Off-cycle defrost is the recommended defrost for medium temp cases. Hot gas or electrical defrost is the rec-
ommended defrost for low temp cases. There are some exceptions, please refer to Case Data Plate. Refer to www.
kysorwarren.com for other electrical data and information.
CAUTION: Failure to maintain maximum design conditions may result in operational issues such as the following: in-
creased BTUH load, high product temperature, coil icing, product frosting, case 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 BTUH load, high product temperature, coil
icing, product frosting, and external sweating.
Case Installation
These reach-in cases may be installed individually or in a continuous line up consisting of multiple 2-door, 3-door,
4-door and 5-door models using a joint kit. A Plexiglas divider kit must be used between cases operating on different
refrigera- tion systems. The divider will be factory installed if specied on order.
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.
4. Ensure oor 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 connec-
tions section of this manual.
6. Ensure location will allow connection to drain lines and the drain line, when installed, will meet the recom-
mendations 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.
CAUTION: To prevent condensation on the end panels of cases, allow a minimum of 3.0 inches for medium temp
cases, and 6.0 inches for low temp cases, 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, if this space is not possible.
IMPORTANT NOTES:
(1)At ASHRAE conditions. For conditions above 75F and 55% RH increase defrost time by 15min. ASHRAE/ ARI:
Total Display Area (FT2) and Gross Volume (FT3).
For sizing conventional/individual condensing units, add 8% to BTUH load.
Where termination temperatures are given, mechanical defrost termination is required.
Defrost duration is at ASHRAE (75F, 65% RH), Timed termination is 60 min at elevated conditions Electrical data
voltage is 115/60/1 except defrost heater which is 208/60/1.

Unpacking
WARNING: Use caution when removing the strapping in the following procedure, as the shelves are very heavy and
could fall causing personal injury or equipment damage.
1. Remove all shipping tape from lamps and ensure that all lamp ends are snapped in place.
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, nd the highest area of the oor to place the rst case.
3. All cases must be located on a rmly based oor and be leveled within plus or minus 1/16 inch.
4. Use metal shims where required to support entire length of the case(s) at each base leg (front and back).
All base legs must be shimmed under the skid rail where the base leg meets the lower rails (typically every
4’ on 4’ and 8’ cases, and every 6’ on 6’ and 12’ cases). If the case is equipped with adjustable leveling
legs, all legs should be adjusted so that all are making equal contact with the oor for equal weight distribu-
tion. WARNING! If any part of the case rail or leveling leg is not supported at each base leg, the case can
appear out of level or become damaged when product weight is added.
5. If multiple cases are to be installed, refer to the oor plan and install the rst case in the lineup by snapping
a chalk line where the front and rear of the cases are to be located.
6. Continue the chalk line if multiple cases are to be installed. The rst case is typically the case that is at the
highest area on the oor.
7. Connect water drain line. Reference waste outlet (drip pipe) description and location procedure later in this
manual.
8. Connect input AC power. Reference electrical installation procedure later in this manual.
9. Connect refrigerant lines. Reference procedure later in this manual.
10. Install all ends, caps, and trim per the applicable instructions contained in this manual.
11. Remove shipping tape on uorescent lamps and remove all other shipping material.
12. 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.
CASES MUST BE LEVELED FROM FRONT TO BACK AND END-TO-END AND SUPPORTED CONTINUOUSLY
AS NEEDED WITH SHIMS
Installing Subsequent Cases
NOTE: All cases are factory numbered with line up and position numbers. Make sure that cases are installed in order
(line up sticker found on the fan plenum or door and on the back panel of the case).
If additional cases are to be installed, follow the same procedures as described in the installing rst case procedure
(above), in addition to the following:
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.

Joining Instructions
Two or more cases of like models can be joined together to form a continuous line up. Before lining up cases, inspect
refrigeration lines, electrical connections, and controls to ensure cases are in the proper line-up and are in the proper
sequence. Reference and become familiar with the below gure, and then join the cases using the instructions that follow.
Line Up Bolt Holes on Side of Cases—See Caulking Diagram Below
1. A Plexiglas divider and EPR valve must be used when joining a case with a different model case.
2. Apply foam insulation tape and caulking around the side of the case as shown in the diagram above.
3. Next, remove access covers and back panels. The back panel is removed by lifting it upward and outward
from the bottom and then dropping it down. Line up holes and insert the small lineup bolts (see diagram) in the end
frame in the bolt-hole 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.
4. Inspect joint for proper air and watertight seal inside and outside the case.
5. Replace line up access cover plugs and back panels.
6. 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.
1. Move cases as near their permanent location as possible before removing shipping braces, skids, or rollers.
2. Remove skids, shipping braces, and optional casters, if provided.
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/placed into position and properly leveled.
6. Before lining up cases using the front and rear edges as a baseline, inspect refrigeration lines, electrical con-
nections, and controls to ensure cases are in proper line up and are in proper sequence.
7. Remove shipping tape on uorescent lamps and remove all other shipping material. Follow all joining to con-
nect cases in a line-up.

Waste Outlet (Drip Pipe) Description and Location
These cases are equipped with 1 1⁄2” inside diameter PVC waste outlet connection that terminates under the re-
frigerator below the insulated bottom. See plan diagrams showing where connections can be made. The water seal
trap is shipped loose for eld installation.
NOTE: Improperly installed drip pipes can seriously affect the operation of this case and result in increased mainte-
nance cost. 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 oor drain or sewer connection.
Case Freezing
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 Kysor Warren cases have drain strainers. This information applies only to the cases equipped with
strainers.
The drain strainer is used to keep debris or any foreign objects from entering the PVC drain, which could cause block-
age. To install, insert into drain until drain strainer stops. It will not be ush. Strainer will exceed hub by 1”.
DO NOT atten drain strainer.
NOTE: 1½” Drain Pipe.
CASES MUST BE LEVELED FROM FRONT TO BACK AND END-TO-END AND SUPPORTED CONTINUOUSLY
AS NEEDED WITH SHIMS
Shelf standards on back wall should
be even when leveled properly.
