CUSTOMER CABINET PROVISIONS
Customer Cabinet Provisions
• Customer provided cabinet must adhere to the minimum requirements in ANSI/UL Std. 471 and
ANSI/NSF Std. 7.
• Among the factors that are to be taken into consideration when judging the acceptability of a
cabinet or similar enclosure are mechanical strength, resistance to impact, moisture-absorptive
properties, flame resistance, resistance to distortion at temperatures to which the material may
be subjected under conditions of use, and resistance to corrosion.
• Customer provided cabinet or similar enclosure shall have the strength and rigidity necessary to
resist conditions of intended use without increasing the risk of fire or injury to persons due to total
or partial collapse. Cabinet or similar enclosure must be strong enough to hold weight of cabinet
and intended product load. Dry weight (no product in case) exceeds 500 pounds.
• A nonmetallic cabinet or similar enclosure (or part of an enclosure) shall have a flame spread
index of not more than 200 when tested in accordance with the Standard for Tests for Surface
Burning Characteristics of Building Materials, UL 723.
• The cabinet or similar enclosure shall be constructed and assembled to reduce the risk of fire
due to the emission of molten metal, burning insulation, flaming particles, or the like, through
openings onto flammable material, including the surface over which the refrigeration is mounted.
• A sheet metal cabinet or similar enclosure is to be judged for acceptability with respect to its
size, shape, metal thickness. Sheet metal such as galvanized or stainless shall be 0.30 inch (22
gage) or greater.
• Steel enclosures shall be protected against corrosion by metallic or nonmetallic coatings, such
as plating or painting.
• The refrigeration access panel/door shall be arranged so that main power switch, refrigeration
controller and refrigeration package are accessible without removing parts other than access
panel/door.
• A hinged or pivoted panel shall be positioned or arranged so that when it is in an open position
falling or swinging due to gravity or vibration will not cause injury to persons.
• For electrical protection when installed in its intended manner, louvers and other openings in the
enclosure shall be constructed and located to reduce the risk of unintentional contact with mov-
ing, live or hot parts such as fan blades and condensate trays. The minor dimension of such
openings shall not exceed 3 inches—See Table 6.1 for Clearance from Openings. Tools are re-
quired to remove covers, panels or grilles unless interlock is provided.
• Ventilation openings/louvers shall be free of sharp edges and burrs and have spaces large
enough to allow for easy cleaning. Louvers that may be subject to splashes, spills, and overhead
drips shall be of a drip-deflecting design.

Service Top Cutout Dimensions
Note: See Manual Cover for DO3637R, DO4837R,
DO3623R & 4823R Service Top Cutout Dimensions.
Clearance Dimensions
The Refrigerated section must maintain airflow clear-
ance. Dimensions are as follow.
1. 4" Minimum Spacing from bottom of refrigeration
frame to bottom of cabinet or floor required for ade-
quate air flow.
2. 9 1/2" Countertop / Facia enclosure space on cabi-
nets or counter to allow for pullout system slide-out.
3. 15" Minimum opening in back of cabinet or counter
(to pull out refrigeration system).
4. Back of counter / cabinet must be vented at specific
sizes to allow for proper air intake and air exhaust.
See Venting Instructions sections for specifics.
5. Obstruction or restriction of air can void warranty.
Note: See Venting Instructions sections (next two
pages) for more specific Air Intake and Air Exhaust

2. Display Case Setup
• SCC® Service Drop-In Refrigerated Merchan-
diser Case consists of two sections: The Upper
Display Case and Drop-In Refrigerated Section.
• As both sections make up one conjoined unit, it
is both large and heavy. A team effort is re-
quired for lowering Case into the Customer Sup-
plied Base.
• After lowering into Base, adjust into position al-
lowing Case to gingerly rest on Counter Top
without marring.

START-UP AND OPERATION
Case Start-Up
• Plug cord into a certified electrical outlet with
ground.
• Turn on the Main Power Switch. Switch is in
the Drop-In Refrigerated Section on the rear
right hand side of base.
• The Temperature Control Module (LED) will
illuminate. Evaporator coil fans and the
compressor motor should turn on.
• From the front of the case, raise the deck to
confirm that the coil fans are functioning
properly.
• Turn on the lights. Light Switch is in the Up-
per Display interior of the case at rear right
side (see illustration at right).
• First time lighting may require a short warm
up period for the bulbs. Slightly dim or a
flickering of new bulbs is normal.
Temperature Settings
• This case has been tested to maintain a
temperature at or below 5° Celsius / 41°
Fahrenheit.
• When the merchandiser is in a start up
mode or has been idle for a long period of
time, the unit will require 30 minutes in order
to pull-down to temperature.
• Spirit-Filled Thermometer located in refriger-
ated compartment is for monitoring warmest
air temperature in accordance with NSF®
Std. 7 (see illustration at right).
• The temperature is controlled by a Tempera-
ture Control Module. It is located at the
lower-right area (from the case rear) of the
Drop-In Refrigerated Section. See top-right
illustration for general location.
• If a temperature setting change is
required,refer to the instructions for the
CPC® (ESC3) Temperature Control
Programming operating section of this man-
ual
• Note: See Technical Data section of this
manual for proper settings to maintain prod-
uct temperature per model.

Refrigeration Access, Connections &
Servicing
Assembly or disassembly and servicing to
be accomplished by licensed refrigeration
contractor.
• Refrigeration Unit slides directly out from
lower section to allow for servicing.
• Service connections are located in the
Refrigeration Slide-Out (shown at right).

evaporator pan for case condensation.
Insure evaporator pan is plugged in 110V
receptacle inside base, and positioned
under PVC drain and on base frame.
• When pulling or pushing unit in or out under
the case, use caution to avoid damage to
copper refrigeration lines, hoses and cable.
• Insure that the flexible drain hose is fully
inserted into the slot of hose support for
proper drainage. See illustration on next
page for general location and specifics.
Temperature Control Module
• Temperature Control Module is located in
the Electrical J-Box.
• The temperature is controlled by the
Temperature Control Module. It is located
at lower-right area (from the rear) of the
Drop-In Refrigerated Section. See top-right
illustration for general location.
• If a temperature setting change is required,
refer to the instructions for the CPC®
