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.
