Installation, Operation, Use and Care of Model HQC135 & HQC200 QuickChillers SAVE THESE INSTRUCTIONS GENERAL The HQC135 QuickChiller is designed for rapid chilling of 135 pounds of food (9 pounds of food per pan in 15 pans) from 150°F to 37°F in approximately 90 minutes. The rapid chilling process preserves food quality, texture and nutritional value for up to 5 days. As many as 5 chillings can be handled per 8 hour shift.
Fully assembled units have the coil and fan unit, probes and controls prewired. Place assembled unit in final position ready for connection of refrigeration lines and electrical supply. Compressor unit can be located remote or self-contained (mounted on top of the cabinet with quick-connect couplings and lines in place). Alternatively, the chiller can be shipped disassembled (knocked down), requiring onsite assembly. When chillers are shipped dissassembled, lay out panels in a staging area.
PANEL ASSEMBLY Each panel is locked in place with the Cam Fast lock using the hex tool supplied (Fig. 3). Each wall panel is locked to its adjacent sides and roof. When an insulated floor panel is provided, wall panels are cam locked to the insulated floor panel. If no insulated floor panel is supplied, each wall panel should be installed with its black vinyl screed fitted on the bottom of the panel.
ASSEMBLY If a 3" insulated floor is supplied, position and level floor panel first. Cam lock the wall panels to the insulated floor panel. Black vinyl screeds are only supplied if the insulated floor panel is not ordered. If the stainless steel sheet metal floor is to be installed, refer to the Technical Data / MSDS from the adhesive manufacturer and follow the Assembly Instructions provided. For all panels, peel off all vinyl coverings to expose the stainless steel surfaces inside and outside.
INTERNAL ELECTRICAL CONNECTIONS Remove the lid from the electrical box on top of the cabinet (Fig. 8). On the front of the cabinet, remove two screws and swing the control panel open. On the front of the cabinet beside the control panel, turn the black knob and swing the printer panel open. From the top of the cabinet, inside the electrical box, insert a short plastic tube into the plastic tubes foamed into the door frame panel. Refer to TUBE #1 and TUBE #2 in Fig. 8.
Push the four control cables with connectors [ J5 ], [ J7 ], [ J9 ] and [ J12 ] down TUBE #2. Refer to the table below and Figs. 8 and 10. Connect the four cable connectors to the control board as shown in Fig. 11. Attach the cables to the hinge with the wire-wrap provided. Once all wires are connected and secured in the controller section, pull up the excess length so the wires do not hang freely in the controller section (Fig. 9). From the top electrical box, seal TUBE #1 and TUBE #2 (Fig.
Product Probe Assembly The product probe junction box is assembled on the side wall panel behind the door hinges. Remove the cover from the product probe junction box. Push the product probe wires down from the ceiling through the hole at the top of the product probe juction box (Fig. 12). Extend the connectors so Connector #1 is at the top, Connector #2 is next, Connector #3 is below Connector #2, and Connector #4 is at the bottom.
Temperature Control Sensors Push the three refrigeration temperature control sensors down through TUBE #3 (Fig. 8) from the electrical box on top of the cabinet (Fig. 15). Install the three temperature control sensors in their proper locations. Install the Air sensor (Fig. 16) on the side panel. Place the Coil sensor on the refrigeration coil header (Fig. 17). Install the Over-temp sensor (Fig. 18) at the top of the left wall panel, inside the cabinet.
Fans and Defrost Heaters Bring all connector blocks from the coil and fan section (fans and defrost heaters) up through TUBE #3 and TUBE #4 to the electrical box (refer to Fig. 8, page 8). Mate the connector blocks with matching connector blocks from the ceiling electrical box. Seal TUBE #3 and TUBE #4 around the wires with proper insulation. Duct seal (putty) is supplied with the cabinet.
ELECTRICAL CONNECTIONS WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE APPLICABLE PORTIONS OF THE NATIONAL ELECTRICAL CODE AND/OR OTHER LOCAL ELECTRICAL CODES. WARNING: DISCONNECT ELECTRICAL POWER SUPPLY AND PLACE A TAG AT THE DISCONNECT SWITCH INDICATING THAT YOU ARE WORKING ON THE CIRCUIT. Whether the condensing unit is remote or mounted on top of the cabinet (available on HQC135 only), there is a separate power supply for the condensing unit.
INSTALLATION — REMOTE CONDENSING UNITS Prior to installing the condensing unit, test the electrical service to assure that it agrees with the specifications on the data plate located on the condensing unit frame. GENERAL The Model HQC135 Chiller can be purchased with a remote condensing unit. The HQC200 will always be provided with a remote condensing unit. Condensing unit sizes are 3 or 31/4 HP for HQC135 and 5 HP for HQC200.
PIPE SIZING GUIDELINES Piping design and line sizing is the responsibility of the installer. The following table can be used as a guideline. The ‘Net Distance to Condensing Unit’ column allows 50% of the Distance for the equivalent restriction to refrigerant flow caused by elbows.
WATER COOLED CONDENSING UNITS Water cooled condensing units are equipped with water valves which control the rate of water flow through the condenser based upon compressor head pressure. The maximum allowable working pressure on these valves is 150 psig, so a pressure reducing valve may be required. The location of the condensing unit should be such that it will not be exposed to ambient temperatures below freezing.

GLOSSARY Alarms — Sets the buzzer intervals after the Door is Open or when to be notified that the Compressor needs to be Cleaned. Buzzer — The control’s buzzer can have its volume and tone adjusted in the System Parameters. By Temp — Chill cycle that terminates when the probes reach the Target Temperature. By Time — Chill cycle that terminates after a set amount of time has lapsed.
GLOSSARY cont. Remote Alarm — The chiller can be wired to a remote alarm which will provide notification of certain irregularities: Printer Error, Cycle End, Door Open, High or Low Temperatures or Power Failure. If Cycle Running is chosen, the remote alarm circuit will close when a chill cycle is running and all other remote alarm settings are overridden (reset to NO).
MAINTENANCE CLEANING Wash, rinse, and sanitize the product probes before and after use as you would any food-contact utensil that measures temperature. Chiller surfaces of stainless steel should be wiped clean with a damp cloth or mild cleaning solution. DO NOT flush with running water. Avoid the use of solvents around plastic or painted areas; clean these with a damp cloth moistened with a solution of mild detergent and warm water. Clean hinge hardware with a chrome cleaner.
