2/6/2006 1Addendum – Ballast Relocation
INSTALLATION & OPERATION MANUAL ADDENDUM
BALLAST RELOCATION
The ballast for this case has been relocated as of January 09, 2006. The advantage of the new location
allows for more shelf space and lowers the BTU. The information we have placed in this addendum is
for the shelf light ballast only. For any other information, refer to the manual or contact our office at 1-
800-866-5596.
Ballast Location/Connections
Ballasts are located in canopy or the raceway. See wiring diagram for layout.

WARNING! It is imperative that the pins of the bulbs and the shelf power cords be
completely seated in their respective lamp holder or receptacle (see pictures below). If they are
not completely seated, an electrical arc could occur which will cause the lamp holders to melt and
become an electrical hazard. Care must be taken during cleaning, product stocking and re-
lamping processes to insure that the bulbs and shelf cords are not dislodged.
Note: The fluorescent bulb is capable of lighting even if the bulb and shelf power cord are not
completely seated.
Note: The shelf light harness has power interruption circuit and ALL shelves must be plugged in
correctly before any shelf lights will work. The shelf plugs are now located on the right side of each
back panel. (See picture below).
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.

Introductions – General Information
This manual has been prepared for our customers and the personnel involved in setting up and
maintaining our cases.
The Kysor//Warren multi-shelf self service dairy cases are designed to merchandise packaged
dairy/deli 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 75º dry-bulb
temperatures and 55% relative humidity.
CAUTION: Failure to maintain maximum design
conditions may result in operational issues such as: increased
BTUH load, high product temperature, coil icing, product
frosting, and external sweating.

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 for all damages must file 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 the Kysor//Warren cases provided the correct expansion
valve is equipped with the case when ordered (i.e., R404A required for the end user requires
specifying the correct expansion valve for R404A 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.
NOTE: Refer to Case Data Control Settings for refrigeration requirements.
Heat Exchangers
Heat exchangers are standard in some models, optional in other models, and are not needed if
mechanical sub-cooling is incorporated in the system design. They are an aid to increasing
operating efficiency and reducing frosting and flood-back to the compressor.
