Hazard Communication Standard (HCS) -

The procedure in this chapter include the

use of chemical products. These chemi-

cal products. These chemical products

will be highlighted with bold face letters

followed be the abbreviation (HCS). See

the Hazard Communication Standard

(HCS) Manual for the appropriate Mate-

rial Safety Data Sheet(s) (MSDS).

This piece of equipment is made in America

and has American sizes on hardware. All

metric conversions are approximate and

vary in size.

INSTALLATION

WARNING: Do not puncture the skin of the

Staging Cabinet with any tools or fastening

devices. Electrical shock or component

damage could result.

The staging cabinet should be placed on an

approved table or shelf to allow easy access

for loading and unloading of product. For

proper operation, the cabinet must be level.

Electrical Connection

The Staging Cabinet is available from the

factory as a 120 VAC unit for domestic use, or

as a 240 VAC unit for foreign use. The data

plate on the side of the unit will specify the

correct electrical supply. The unit requires a

grounded receptacle with a separate electrical

line protected by a fuse or circuit breaker of

the proper rating.

WARNING: The cabinet must be ad-

equately and safely grounded according to

local electrical codes to prevent the possi-

bility of electrical shock.

Cabinet Preparation

When the cabinet is turned on for the first time,

you may experience the following:

A. A burning odor.

B. Slight smell of smoke.

This indicates oils used on stainless steel and

the new electrical connections are burning off

residue.

It will take 3 to 4 hours of burn off to eliminate

this inconvenience. The burning off procedure

should be done the day before you intend to

use the cabinet. It should be done in a venti-

lated area away from the kitchen and custom-

ers. After the burn off procedure is complete,

thoroughly clean the staging cabinet following

the daily cleaning procedures.

EQUIPMENT SET-UP AND

CLOSE PROCEDURES

The Introduction and Installation sections of

this manual should be read before operating

the cabinet.

This section contains an explanation of all

controls and components and information

on operating procedures and daily mainte-

nance.

Heated air inside the cabinet is circulated

over 2 heating coils and across a water pan.

The warm, moist air is then forced down-

ward through air ducts on each side of the

unit. The heated air is dispersed over and

under the product from openings in the air

ducts. These openings are varied in size to

promote uniformity of heated air throughout

the cabinet.

Set-up

Place the power switch in the ON position.

If humidity is desired, remove the water pan

and put approximately 1” of hot water in the

pan. Then return the pan to the unit.

NOTE: Be sure to push the water pan in

as far as it will go so that it does not

block air from the temperature probe.

This will assure proper operation of the

controls.

The display will increase in temperature,

indicating the cabinet is heating. When the

operating preset temperature is reached the

“HEAT ON” LED will turn off and the display

should stay at the preset temperature.

Once the preset temperature shows on the

display, product can then be placed in the

cabinet. Slide a tray of product into the

racks, close the door, and press the appro-

priate timer button on the controls.

Vent Adjustment

The vent setting corresponds to the number of

trays of product. With one tray of product, set

the vent at No. 1. With two trays of product, set

the vent at No. 2, and so on.

Daily Cleaning Procedure

1. Move the power switch to the OFF

position.

2. Disconnect the electrical supply to the

cabinet.

WARNING: Allow the unit to cool before

cleaning by opening the door(s) slightly.

3. Remove trays and racks from the inside of

the unit and clean them thoroughly with a

hot solution of McD All Purpose Concen-

trate (APC) (HCS) from the sink

proportioner.

CAUTION: Most surfaces of the unit can be

cleaned with a soft cloth, cleanser, and

water. DO NOT USE ABRASIVE CLEANERS.

4. Remove the water pan and clean it with a

soft cloth and a hot solution of McD APC

(HCS) from the sink proportioner.

5. Wipe the control panel with a damp cloth.

Do not splash water around the controls.

6. Clean the exterior of the cabinet with a

damp cloth.

NOTE: The doors can be easily pulled from the

hinges for easy cleaning.

7. Clean the interior of the cabinet thoroughly

with a cloth and a hot solution of McD APC

(HCS) from the sink proportioner.

8. Put the side racks and water pan back into

the cabinet.

9. Leave the door open over night to allow the

unit to dry out.

Temperature Regulation

It is possible to regulate the setpoint tem-

perature. Depress and hold the PROGRAM

button for one second, then the control

beeps and the top display shows “Prog,”
