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 moving, 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 required 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.

CLEARANCE AND AIR FLOW

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 clearance. Dimensions are as follow.

1. 4" Minimum Spacing from bottom of refrigeration frame to bottom of cabinet or floor required for adequate air flow.

2. 9 1/2" Countertop / Facia enclosure space on cabinets 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 clearance dimensions for Models DO3637R & DO4837R.

3. Seal Upper Display Case to Base

• NSF® Listed Industrial Grade Silicone Seal-

ant is recommended.

• Clip tip to allow approximately 1/8” to 3/16”

diameter hole.

• Beginning at case

rear, run a consistent, solid bead of silicone around entire perimeter.

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 required for lowering Case into the Customer Supplied Base.

• After lowering into Base, adjust into position al-

lowing Case to gingerly rest on Counter Top without marring.
