Installation, Operation, Use and Care of

HQC45 QuickChill, HQCF45 QuickChill / Freezer,

& HQC90 QuickChill

SAVE THESE INSTRUCTIONS

GENERAL

The HQC45 QuickChill is designed for rapid chilling of 45 pounds of food (9 pounds of food per pan

in five 12" x 20" x 2

⁄2" pans or five 18" x 26" sheet 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 Automatic Chill/Hold mode can be used for overnight chilling.

The HQCF45 QuickChill / Freezer is designed to chill exactly like the HQC45 and it can also freeze product down to – 20°F. Freezing time varies according to the initial and final product temperatures as well as product type and quantity. Coated wire shelves can accommodate five full-size

12" x 20" x 2

⁄2" pans or five 18" x 26" sheet pans.

The HQC90 QuickChill is designed for rapid chilling of 90 pounds of food (9 pounds of food per pan

in ten 12" x 20" x 2 shelves can accommodate ten full-size 12" x 20" x 2

⁄2" pans) from 150°F to 37°F in approximately 90 minutes. Optional coated wire

⁄2" pans or five 18" x 26" x 21⁄2" pans.

Chill and Freeze times are dependent upon product type, thickness, density, thermal conductivity, and

type of covering. For best results, approximately 9 pounds of product per 12" x 20" x 2

⁄2" pan or 18" x 26" sheet pan is recommended. If more product per pan is being chilled, the time required to chill will be increased.

Cabinets are provided with a junction box in the lower section which allows for permanent, hard-wire connection. Stainless steel legs or casters are available accessories.

The durable stainless steel interior has coved corners for ease of cleaning. The exterior sides, front, and back are stainless steel. Left or right door swing is available on order and cannot be changed in

the field. Compressors supplied by Hobart are rated

are rated

⁄4 HP on HQC90. Refrigerant is R404A. Remote refrigeration system or water cooled

⁄4 HP on HQC45 and HQCF45. Compressors

refrigeration system are optional. The microprocessor controller provides the ability to:

• Select the mode of operation from a standard menu: Automatic (probe) or timed chill or freeze.

• Display the current air and product temperatures and time.

• Monitor product temperature with three probes during chill mode to reduce chances of freezing.

• Allows the operator the choice of enabling surface protection that will limit the air temperature to 28°F in the latter part of the chill cycle.

• Provide service diagnostics to quickly check machine functions and control circuitry; provides quick connect/disconnect of the controller.

The printer is part of the controller and provides the ability to:

• Print data from the last chill cycle or from all chill cycles since 12:00 midnight.

• Print the time and date information for each cycle.

• Report chill temperatures vs. time at ten minute intervals.

INSTALLATION

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

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.

DO NOT LAY THE CHILLER ON ITS FRONT, BACK OR SIDES. EXERCISE EXTREME CARE WHEN REMOVING THE CRATE BOTTOM ESPECIALLY WHEN THE LAST SHIPPING BOLT IS REMOVED. CABINET MUST BE PROPERLY BLOCKED AND STABLE.

Cabinet is bolted onto a wood shipping base from underneath using the Threaded Hole (Fig.1). Remove shipping bolts.

LEGS OR CASTERS

The HQC45, HQCF45 and HQC90 must be installed with legs or casters. WARNING: THE CABINET MUST BE BLOCKED AND STABLE BEFORE INSTALLING THE LEGS

OR CASTERS. Legs (Optional) To install the legs, raise up and block the cabinet a minimum of 7" from the floor and thread the legs

into the threaded holes on the bottom of the cabinet. The chiller must be level to operate properly. Turn the adjustable feet in or out as required to level the

chiller front-to-back and side-to-side (Fig. 1). Casters (Optional) Casters may be supplied for use on self-contained units. The swivel casters with brake should be

installed in front; casters without brake, in rear (Fig. 2). Caster equipped chillers should be located on a level floor.
