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.

2. Display Case Design

 As shown above-left, SCC® service drop-in

refrigerated unit consists of two sections:

> The upper display case

> The drop-in refrigerated section

 As both sections make up one conjoined unit, it

is heavy and cumbersome.

 See next section for instructions on lowering

drop-in refrigerated section into counter.

3. Lowering The Drop-In Refrigerated Section

Into The Counter (Base)

 A concerted team effort may be required for

lowering drop-in section into customer supplied

counter (base). See top-right illustration.

 The following is a proven method to lower the

drop-in section into the customer supplied

counter (base); however, it may NOT be the only

method. A fork lift is required to use this method.

A. Spread the forks (of fork lift) apart to fit under

either side of the upper display case (the

extended part of the unit that rests on counter).

B. Carefully raise into position above counter.

C. Place ¾” blocks of wood under two opposing

sides where it is to be lowered.

D. Lower into the opening of the counter.

E. After it is lowered all the way into the opening, it

will be resting on the two small wood blocks at

opposite sides.

INSTALLATION: SKID REMOVAL / LOWERING INTO COUNTER (BASE) / SEALING

1. Remove Case From Skid

Caution: Case must always remain supported or

center of gravity may allow case to fall. Slide to
