Case Installation
The display cases are installed individually.
Preparation (with modular condensing unit)
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 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 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 that R404A Refrigerant is available 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: 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.
2. Ensure the evaporator cover is installed correctly and the deck pans are installed.
3. Move the case into position.

3/11/2009 19
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 Assembly
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.
3. All cases must be located on a firmly based floor and leveled within plus or minus 1/16 in.
4. 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 and no more than 4 ft. apart. All legs of the case must be properly
adjusted and in contact with the floor.
5. If multiple cases are to be installed, refer to the floor plan and install the first case in the line
up 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 first case is typically the case
that is at the highest area on the floor.
7. Connect water drain line. Reference waste outlet (drip pipe) description and location
procedure later in this chapter.
8. Connect input AC power (SEE Case Data Section).
9. Set condensing unit on top of case at location supplied. Pipe into case using the sight glass
and liquid line filter drier supplied. Follow normal procedures for brazing; pressure testing, and
evacuation of the system. Once system has been evacuated charge system, program controller
and check for proper operation.
10. Remove shipping tape on fluorescent lamps and remove all other shipping material
CASES MUST BE LEVELED FROM FRONT TO BACK END-TO-END AND SUPPORTED
CONTINUOUSLY AS NEEDED WITH SHIMS.

Modular Condensing Unit
Mounting Base & Enclosure
The evaporator pan, control box, and Buck & Boost transformer are factory mounted on a base
plate attached to the top of the case. Condensing unit, enclosures panels, sight glass, & liquid
line filter drier are shipped loose and
Will be field installed. (Refer to pictures below)
Assembly – Modular Condensing Case
The front enclosure panel has a knock out provided for the controller display.
This panel must face the front of the case
