1.0 — General Information and Installation 1.1 INTRODUCTION 1.4 EQUIPMENT SUPPLIED The Alto-Shaam® Quickchiller is a processing refrigeration system designed to rapidly and uniformly cool hot foods through the "chilling danger zone" of 140° to 40°F (60° to 4°C) in two hours or less. Fast cooling minimizes microbial activity, thereby controlling quality and sanitation in prepared foods. As a result, a five-day storage life is achieved. Chill processing stops all cooking activity.

1.0 — General Information and Installation 1.5 RECEIPT AND UNPACKING Upon receipt of the Alto-Shaam ® Quickchiller, note any crate markings for special instructions and check for crate damage. IMMEDIATELY notify the carrier if there appears to be damage to the equipment. The chiller is shipped from the factory, securely fastened to a single shipping pallet and protected by an external wrapping. Carefully remove all external wrappings and other protective coverings.
1.0 — General Information and Installation 1.6.6 ELECTRICAL: The Quickchiller must be installed by a qualified electrician. This appliance must be branch circuit protected with proper ampacities in accordance with the wiring diagram located in this manual. In the U.S.A., the chiller must be properly grounded in accordance with the National Electrical Code and applicable local codes.
2.0 — Control Set-Up and Operation 2.1 START-UP PROCEDURES 2.1.1 Place the branch circuit breaker (main panel) in the ON position. Then place the Quickchiller circuit breaker in the ON position. 2.1.2 The Main Menu screen must appear on the Control display (see figure 2.1.3). If the Main Menu screen appears, skip Sections 2.1.3 thru 2.1.5 and proceed with SET-UP per Section 2.2. If the Main Menu screen does not appear, proceed with Section 2.1.3.

2.0 — Control Set-Up and Operation Ta b le 2 . 4 . 1 CONTROL MODE OVERVIEW Mode Operation Description Auto Chill Refrigeration is controlled only by the food probe(s). Refrigeration continues until all food probes achieve chill setpoint temperature, whereupon the control automatically enters HOLD Mode. Timed Chill Refrigeration is controlled by chill time entered and the cabinet air sensor. While chilling, the cabinet air temperature may become excessively cold prior to chill time expiration.
2.0 — Control Set-Up and Operation 2.5 MAIN MENU HOLD MODE SCREEN The main menu is the starting point for all functions of the Quickchiller. This includes starting the hold, defrost, and chill cycles; report printing; and changing the system configuration. There are four main options shown on the main menu screen. These options are selected with control keyboard buttons "A" through "D." The remaining options are initiated by holding down a number button for 5 seconds.
2.0 — Controls, Operation and Start-Up 2.8 HARDWARE NOTES 2.7 SHUT-DOWN PROCEDURE The Quickchiller can be shut-down at the end of the production day whenever any menu screen which includes STOP=D is displayed. Before starting unit shut-down, make certain all product has been removed from the unit. Press "D" on the keyboard to begin shut-down.

4.0 — Diagnostic and Repair Procedure — CONTROL 4.1 INTRODUCTION 4.2.1 SOLENOID CHECK: The relays, which control the compressors, fans, solenoids, and heaters, can be individually controlled by the microprocessor control set in a manual mode. The following test will verify that these components are being controlled and will verify the operational integrity of the relays and fuse sets. 4.2 CONTROL DIAGNOSIS The main menu is the starting point for this test.
4.0 — Diagnostic and Repair Procedure — CONTROL 4 . 3 CONDENSING UNITS 4 . 4 FA N S , H E AT E R S , S O L E N O I D S The condensing units operate only when the system is in a cooling mode and the food storage compartment requires a decrease in temperature. If it appears the condensing units are not functioning properly and the General Diagnostic Procedure (4.2.4) on the preceding page was unable to pinpoint the specific cause, the following steps should be taken for further diagnosis.
4.5 TROUBLE-SHOOTING GUIDELINES - CONTROL PROBLEM POSSIBLE CAUSE Alphanumeric display is blank. If power is connected to the unit and the main circuit breaker is on, the display on the control should be illuminated with a green tinged background. Control needs to be reset. Unresponsive control. If the control does not respond to operator key presses or the screen on the display appears frozen or sluggish. Control needs to be reset. Power failure threshold is set too low. Control board is faulty.

5.0 — Cleaning & Maintenance 5 . 3 EXTERIOR CLEANING 5 . 1 INTRODUCTION To insure trouble free operation and the highest level of sanitation control, periodic cleaning and maintenance is required. The maintenance system should be aimed at maximizing the efficient utilization of maintenance personnel, minimizing down time, and providing the orderly acquisition of spare parts for support.
T R A N S P O RTAT I O N DAMAGE and CLAIMS All Alto-Shaam equipment is sold F.O.B. shipping point, and when accepted by the carrier, such shipments become the property of the consignee. Should damage occur in shipment, it is a matter between the carrier and the consignee. In such cases, the carrier is assumed to be responsible for the safe delivery of the merchandise, unless negligence can be established on the part of the shipper. 1.
