AP20BC175-2 Manual INTRODUCTION Blast Chiller Model AP20BC175-2 is used to rapidly chill cooked foods to temperatures suitable for refrigerated storage. It is capable of lowering the core temperature of up to 200 pounds of most foods from 160o F to 40o F in 90 minutes. Food is loaded into 12" x 20" x 2-1/2" pans. All units are sized to accept one rack containing up to 20 pans. Model AP20BC175-2 has an integral temperature recording device (printer) and 4 food probes.
AP20BC175-2 Manual OPERATING CYCLES The operator can choose from the following 3 operating cycles: MODE END FOOD TEMP.

AP20BC175-2 Manual INSTALLATION AT DIFFERENT LEVELS If the remote condensing unit is installed at a higher level than the cabinet (FIG. 6) insert a siphon in the return line at every 6 ft. of difference in height. If the remote condensing unit is installed at a lower level than the cabinet (FIG. 7) it is not necessary to insert any siphons. FIG. 7 FIG. 6 Insert a siphon at the beginning (a) and at the end (b) of each riser CONNECTION PIPING FOR REMOTE CONDENSING UNITS MODEL SUPPLY LINE DIA.
AP20BC175-2 Manual INSTALLATION WARNINGS READ ALL OF THE INSTRUCTIONS IN THIS MANUAL BEFORE YOU ATTEMPT TO INSTALL THE EQUIPMENT AND CAREFULLY FOLLOW THEM. ALWAYS DISCONNECT THE UNIT FROM THE POWER SOURCE BEFORE PERFORMING ANY SERVICE OR MAINTENANCE. INSTALLATION AND SERVICE MUST BE PERFORMED BY A QUALIFIED SERVICE AGENCY APPROVED & AUTHORIZED BY AMERICAN PANEL CORPORATION. DOING OTHERWISE MAY VOID THE WARRANTY.
AP20BC175-2 Manual 4. At least 15” clear space is required above the unit for service. 5. At least 6” is required on both sides of the cabinet (for servicing the control panel and door opening). CONNECTION TO THE REMOTE UNIT The specified diameters (see chart on page 6) for the copper tubing used to connect the remote condensing unit to the cabinet are adequate for a separation of up to 60 feet. For greater distances, contact the factory for instructions. NOTES: 1.
AP20BC175-2 Manual SPACES AROUND THE CABINET • At least 15" clear space is required above the unit for service. • At least 6" clear space is required on both sides of the cabinet. • At least 6" clear space is required on the rear of the cabinet for drain hookup and maintenance. • Enough space should be provided in front of the cabinet to fully open the door. STARTING & TESTING THE UNIT 1. To charge the unit, use the "HARD" cycle and the "MANUAL" mode.
AP20BC175-2 Manual USING THE HURRICHILL™ TECHNOLOGY BLAST CHILLING All cooked food rapidly loses its quality and aroma if it is not served promptly. Natural bacteria growth, the main reason why food becomes stale, takes place at an exponential rate between 140°F and 40°F. However lower temperatures have a hibernating effect that increases as the temperature drops, thereby gradually reducing bacterial activity until it stops altogether.
AP20BC175-2 Manual PANNING AND LOADING PANNING 1. Standard pan depth is 2-1/2”. Other depths can be used but are not recommended as their use would require an increase in the cycle time. 2. Stainless steel or aluminum pans are recommended, as plastic containers will increase the chilling time. 3. Crockery or stainless steel cylinders, 6” dia. and 10” max. height, are acceptable. 4. Slack filled Cryovac bags can be used if placed on wire shelves. 5.

AP20BC175-2 Manual CLEANING THE CONDENSER For correct and efficient operation of the blast chiller, it is necessary that the condenser be kept clean so that air can circulate around it freely and come into contact with the whole of its surface. This operation (to be performed every 30 days, max.) can be accomplished using a brush (non-metallic) to remove all the dust and dirt from the condenser fins. Remove the finned grid to gain access to the condenser. Fig.
