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. The chiller can accommodate a roll-in rack or cart which will hold 15 full-size 12" x 20"

1

/2" pans (2 pans per level). Maximum cart dimensions are 271/2" wide x 303/8" deep x 743/4" high.

x 2 The Model HQC200 QuickChiller is designed for rapid chilling of 200 pounds of food (9 pounds per pan

in 22 pans) from 150°F to 37°F in approximately 90 minutes. Chill time is dependent upon product type, thickness, density, thermal conductivity and type of

covering. For best results, approximately 9 pounds of product per pan is recommended. If more product is being chilled, the time required to chill will be increased. A thin covering (plastic wrap or aluminum foil) on the top of the pan is recommended.

The stainless steel interior has radiused corners for ease of cleaning (per NSF Standard Number 7); exterior sidewalls are also stainless steel. Location of RS232 port is standard in front behind the printer door and optional at the top.

The SmartChill™

• Select the chill mode: By Product, By Time or By Temperature.

• Display the current air and product temperatures and time.

• Monitor product temperature with four smart probes to reduce chances of freezing.

• Select Soft Chill to reduce the chances of freezing in the final phase of chilling.

• Provide service diagnostics to quickly check machine functions and control circuitry.

• Send Chill Cycle data via RS232 port to SmartChill™ computer software, state-of-the-art HACCP data management.

The standard printer provides the ability to:

• Print data from the last or any chill cycle with time, date and temperature information.

• Charts chill temperatures vs. time at intervals that can be set by the supervisor.

An optional second printer can print a condensed ‘Label’ type of report with Product and User info.

• Printers provide HACCP reporting of chill data.

Chillers can be shipped either with panels fully assembled or disassembled for on-site assembly.

controller provides the ability to:

The condensing unit on model HQC135 can be remote or self-contained. On model HQC200, the condensing unit is always remote.

INSTALLATION

UNCRATING

Immediately after unpacking, check for possible shipping damage. If the chiller is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery.

Before installing, check the electrical service to make sure it agrees with the electrical specifications on the rating plate located on the side panel inside the cabinet on the hinge side.

– 4 –

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. Lay panels on foam blocks used for packing to avoid scratches on the panels. Identify fasteners and components.

LOCATION

Allow reasonable clearance for installation of electrical and refrigeration lines above the chiller cabinet.

INSTALLATION WITH OPTIONAL INSULATED FLOOR PANEL

The chiller can be ordered with an optional 3" deep floor panel, without a floor panel or with a stainless steel sheet floor. When installed with 3" insulated floor panel, the chiller can be installed in a recessed area of the floor or with an optional ramp.

The floor panel is preferred to be installed in a recessed area so carts can roll flat into the Chiller. When installing a recessed floor, a pit must be constructed in the concrete slab at least 4 inches in depth with

1

a

⁄2" clearance around the perimeter. The 4 inch depth is a minimum requirement. Floor panels are 3 inches in depth, the remaining inch is used for sand to facilitate leveling (Fig.1). The interior floor of the cabinet should be even with the building floor.

INSTALLATION WITHOUT OPTIONAL INSULATED FLOOR PANEL

If no insulated floor panel is ordered, black vinyl screeds are provided. The wall panels of the chiller cabinet are inserted in the black vinyl screeds during installation (Fig. 2). The chiller should be installed on a smooth level surface. If necessary, further leveling may be provided by shimming between the floor and wall panels.

INSTALLATION WITH OPTIONAL STAINLESS STEEL SHEET METAL FLOOR

The stainless steel sheet metal floor can be glued directly to the building floor before erection of the QuickChill cabinet. Mark the 40" x 50" floor area where the QuickChill will be erected.

Make sure the floor is level before proceeding. If the floor is not level the wall panels will not be vertical, the roof panels will not fit properly and the hinged door will not operate properly.

Both the building floor and the stainless steel sheet must be clean, dry and free from grease, oil, wax or other surface contaminants.

Avoid glue contact with skin or eyes. Provide adequate ventilation. Do not breathe fumes. Follow the glue manufacturer's instructions. Refer to assembly instructions shipped with the floor.

Allow at least 24 hours for the glue to set before beginning installation of the QuickChill cabinet.

On top-mounted, self-contained HQC135, all refrigeration lines are of the proper length. Assemble by connecting the quick couplers. Brazing and welding are not required. Lines are pre-charged with R-404A refrigerant.

On cabinets with remote condensing units, proceed with all refrigeration brazing that needs to be done to bring suction and liquid lines out of the cabinet interior. Bring liquid line from the interior to the solenoid valve installed on top of the cabinet. On standard units, refrigeration lines go out through the ceiling hole. Seal hole around the lines with proper insulation. Duct Seal (putty) is supplied with the cabinet.

Suction and liquid lines have to be installed between the cabinet and the remote compressor. Refrigeration installation and start-up must then be done by a professional refrigeration technician, using recognized industry-standard procedures.

DRAIN LINE INSTALLATION

The drain tube begins at the

7

/8" O.D. stainless steel connection at the bottom of the drain pan, underneath the coil and fan section. If the drain outlet was not selected and drilled, make a hole in the wall panel to exit the drain line. From the stainless steel connection, the drain should either go straight to the front, straight to the rear, or straight to the side. Sufficient copper pipe is supplied to exit the cabinet. Install this copper pipe by attaching it to the stainless steel connection using a small selftapping screw.

Once the drain exits the cabinet, it must be trapped per local code before being extended to an open floor drain. The clearance area around the drain tube where it exits the panel wall must be sealed with an NSF approved sealer.

INTERIOR FINISH DETAILS

Plates are provided on the top front of the coil and fan section. Move the plates up to cover the holes on top of the coil and fan section. Run a bead of silicone sealant all around the coil and fan section, between its stainless steel structure and the foamed walls. Install the cover for the coil and fan section using the six wing bolts, supplied. The square openings should be placed in front of the fan units — louvers, in front of the coil. Fans will not start if the cover is not in its proper position.

INSTALLATION OF REMOTE ALARM (

OPTIONAL)

The Chiller provides a connection for a remote alarm that operates when the buzzer sounds on completion of a chill cycle. This output is a set of normally open relay contacts which close when an alarm occurs. Connections are made to terminals 5 and 6 located in the junction box on the roof per the wiring diagram and these restrictions:

1. Maximum remote alarm rating: 120V at 2 amps resistive or 100 watt incandescent lamp.

2. Connection must be made with 600 volt insulated wire suitable for supply voltage. Do not use bell wire, lamp cord or similar type wire.

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

1

be provided with a remote condensing unit. Condensing unit sizes are 3 or 3

HP for HQC200. Condensing units are available for indoor air-cooled, indoor water-cooled or outdoor

5

/4 HP for HQC135 and

application, to be specified at time of order. Compressor is available in hermetic or semi-hermetic types for HQC135 and HQC200.

DUE TO THE VARIED NATURE, COMPLEXITY AND UNIQUENESS OF REMOTE CONDENSING UNIT INSTALLATIONS, THE HOBART WARRANTY DOES NOT COVER REMOTE INSTALLATION WORK AND DOES NOT COVER CONDENSING UNITS SUPPLIED BY OTHERS.

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 TO INDICATE THAT YOU ARE WORKING ON THE CIRCUIT.

Install electrical conduit and wiring (not supplied) from the power supply to the terminal junction box on the condensing unit. Proper supply voltage, maximum fuse/circuit breaker sizes and minimum circuit amperage can be found on the condensing unit data plate. On outdoor condensing units, wiring must be encased in watertight conduit and use watertight fittings.

It is recommended that a disconnect switch (not supplied) be located near the remotely installed condensing unit for installing or servicing.

Refer to page 13.

CONDENSER RECOMMENDATIONS

For indoor installations, place the condensing unit in a cool, dry place that is easily accessible for installation, cleaning and maintenance. The condenser must be located a minimum of 2 feet from a wall or obstruction. For air-cooled condensing units located in machine rooms or air restricted areas, ventilation is needed to dissipate the heat produced by the condenser. The condenser heat varies during the chilling cycle but could be considered for ventilation purposes to be as follows:

1

3 or 3

/4 HP Condensing Unit 50,000 BTU/h 5 HP Condensing Unit 73,000 BTU/h

– 14 –

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. We recommend the installer minimize restriction to refrigerant flow by incorporating the following features in their design: Use fewer elbows; use long radius elbows when possible; use 45° elbows instead of 90° elbows, if possible. A vertical suction riser greater than 3 to 4 feet in height should have a P trap at the base to facilitate oil return up the riser. For long vertical risers, an additional P trap is recommended for each 20 feet of riser to assure proper oil movement.

OUTDOOR CONDENSING UNITS

Outdoor condensing units are equipped with weather resistant outdoor covers, crankcase heaters and head pressure valves to control the flow of refrigerant through the condenser.

Refrigerant charging of the system in ambients above 70°F requires additional charging equal to the pounds necessary to flood the condenser under low ambient conditions, as defined in the chart below:

MODEL CONDENSING UNIT APPROXIMATE ADDITIONAL

(HP) R-404A CHARGE

HQC135 3 or 31/4 8 lbs HQC200 5 15 lbs

Charging of the system with refrigerant in ambients below 70°F requires caution to prevent overcharging since the pressure control valve will already be partially functioning and the amount of additional charge must be determined.

VALVE AND PRESSURE SETTINGS

LOW PRESSURE CONTROL SETTING

(Refrigerant R-404A)

Low Pressure Cut-In 30 psig Low Pressure Cut-Out 10 psig

The ideal superheat at the evaporator outlet is 8 – 10°F.

– 15 –

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. A chart of water flow requirements for condensing units (page 17) is based upon incoming water temperature and is expressed in gallons per hour per 1,000 BTU/hr refrigeration.

BTU/hr capacities are:

MODEL HP BTU/HR CAPACITY

HQC135 3 or 31/4 24,800 at 10°F Suction and 105°F Condensing HQC200 5 35,800 at 10°F Suction and 105°F Condensing

The water cooled condensing units may be plumbed in series for use with city water supplies or plumbed in parallel for connection to a cooling tower. All water cooled condensing units are refrigerant cooled, and therefore should have superheat settings to maintain return gas temperatures not to exceed 65°F. For additional information, refer to Copeland Technical Bulletin AE 1174-R6, dated January 1, 1985. A copy is available through your sales representative.

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.

By Prod — Chill cycle that terminates after a particular product’s specified chill parameters are

met (the parameters can be set either By Temp or By Time with specific cut-offs for a particular product.

Chill — Chilling Cycle that may end with either Time or Temperature controlled events. (Also

see Soft Chill).

Clock — Allows the Date and Time to be entered so the system’s clock correctly records

chilling events.

Cycle # — The system assigns a consecutive number to each Chill Cycle.

Defrost — System Controlled Defrost occurs after six hours of chilling. The defrost will not

begin during a chill cycle. The system waits until it is in Holding mode before starting the defrost cycle. The Defrost from the Main Menu is a manual defrost that will not run if selected and unneeded. The Defrost cycle requires about 20 minutes.

Fac Presets — Factory Presets are system parameters that are set at the factory but can be

changed by the supervisor.

Hold Prod — After a chill mode has been done or when selected from the Main Menu, the chiller

will act like a regular refrigerator.

Label — A condensed Chill Cycle Report that can be printed on adhesive-backed label stock

by the optional second label printer.

Logging — The time interval at which Chill Cycle data (temperature vs. time) is logged into

memory for record purposes. This time interval can be modified in Sys Par (System Parameters) by the supervisor. The range of settings available for this time interval is: 5, 10, 15, or 30 minutes.

Main Menu — The two initial menus available from the controller after the chiller is turned on.

Mode — Basic chiller operating parameters are available from Sys Par in Setup mode.

Chill mode parameters allow adjustment of the target temperature, the air temperature during chill mode, the hold mode temperature, the high alarm temperature, the low alarm temperature and the maximum chill mode target temperature.

Soft Chill mode parameters apply a modification of some of the Chill settings during the final portion of the chill cycle if Soft Chill is selected. Soft Chill provides additional protection against freezing of surfaces.

– 38 –

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). The supervisor can determine which events the remote alarm will announce by adjusting the settings in the Sys Par (System Parameters) section.

Setup — Specific control settings that can be set by the supervisor which determine how the

chiller will operate.

Soft Chill — Type of chill process that moderates the temperatures and fan speed near the end

of the chill cycle to provide less risk of freezing at the product’s surface.

Supv — A Supervisor is a user who is allowed to identify the users and limit their access to

system parameters, enable products to be selected, set specific product chill parameters, and change system parameters.

Sys Par — System Parameters are control settings that determine how the chiller will operate.

These settings can be adjusted by the supervisor in Setup mode.

Temps in °C — If so displayed on the Sys Par 1 screen, all temperatures will be recorded in °C

(Celsius).

Temps in °F — If so displayed on the Sys Par 1 screen, all temperatures will be recorded in °F

(Fahrenheit).

Oper — An Operator is a user who is allowed to operate the chiller and make reports of chill

cycles performed.

Print — Allows a report of any Chill Cycle and probe to be printed. Chillers equipped with the

optional second printer can print the condensed ‘Label’ type of report. All Chillers can print the ‘Record’ type of report.

Probe # — Each probe is numbered and its temperature vs. time is recorded for each probe #

during every chill cycle and the record can be printed, either at the end of the chill cycle or subsequently.

Product List — A list of products in system memory which can have individual chill parameters

specifically set for each product (assuming that the product is already enabled). Refer to Setup Products.

Record — Type of report that can be printed by all chillers. This report provides a record of time

vs. temperature for a specific Probe and Chill Cycle.

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. Use a solution of warm water and baking soda to clean the gasket; then wipe with a soft cloth. Hinges may require occasional lubrication of the plastic cam. The top of the chiller is not to be used for storage.

CONDENSER COIL WARNING: DISCONNECT ELECTRICAL POWER SUPPLY BEFORE CLEANING ANY PARTS OF

THE UNIT. Check the condenser coil weekly. Air must be able to freely circulate through the condenser. This

surface must be kept free of dirt and grease for proper system operation. Carefully clean dirt and lint from the condenser coil using a vacuum cleaner, whisk broom or soft brush; do not use a wire brush. CAUTION: Do not damage the condenser coil fins. Replace cover. Reconnect electrical power supply.
