INTRODUCTION

The Aladdin Temp-Rite RAC10 high performance air curtain refrigerator is uniquely designed to maintain temperatures of refrigerated pre-plated and pre- packaged products temporarily for food preparation tasks. The horizontal and vertical flow of chilled air across the main opening allows these perishable items to be displayed during service with the door wide open, giving users convenient and unimpeded access during tray assembly meal times.

The condensing unit is located in the base of the cabinet for a lower center of gravity and added stability during transport. Enhanced ventilation is provided by removable louvered front, rear and side grills. Removable access panels located at the front and back of the unit permits easy access for servicing and cleaning the compressor and for servicing the electrical wiring. Air circulation fans and finned, forced convection coil is contained within a top mounted housing. The system has sufficient capacity to maintain cabinet temperatures with the door open for 90 minutes in a normal hospital kitchen environment if recommended procedures are followed. All condensate water is removed automatically by an electric evaporator.

INSTALLATION

Electrical

• Check the data plate for proper voltage and amp draw
• WARNING: This unit uses a three-pronged grounded plug. Verify that the RAC10 is plugged into a properly grounded outlet to avoid the possibility of electrical shock. Do not cut or remove the grounding prong from the plug or use an extension cord
• Use a dedicated electrical outlet with a receptacle for a grounding plug

Location
Selecting a proper location for your RAC10 is important to proper operation.

• Location should be level
• Keep away from extreme heat
• Keep away from steamers
• Don’t place near or under a ventilation duct or hood
• Keep a minimum 6” clearance from the back of the unit
• Ensure the door may open 270o degrees

Clearance
For proper operation and longevity, your RAC10 needs an adequate air supply to the compressor. Allow a minimum of 6” between the back grill of the unit and the wall for proper air flow.

Installation

• Inspect the unit for damage if you have not already done so (see Section III)

• Remove all packaging material (Save until you are sure there is no shipping damage)
  Do Not Lay Unit down

• Tray slides have tabs formed into the side. Simply put the tab into the square hole in the side of the cabinet and push down to secure. The tray slides can be installed in a horizontal or sloped position which will allow the product to slide forward on the sheet pans.

• Locate unit (see Location above)

• Plug the unit in (see Electrical above)

• Turn the selector switch to the ON position, the display should illuminate

• Keep the door closed until unit cools down to setpoint

OPERATION

Operating parameters
During tray assembly, the open door holding time may be affected by the following factors:

• Room ambient temperatures
• Humidity levels
• Air disruption (such as a hood, vent, or air return)
• Amount of time air curtain is allowed to precondition air
• Amount of time unit is allowed to precondition the food
• Food temperatures when placed into the units
• Type of food, food packaging, and profile of food
• Condition of the unit (regularly maintained and cleaned condensing unit)

Open door operation
To better maximize efficiency of the 90 minutes designed for open door access please do the following:

• Set temperature should remain at factory pre-set 34°F (1.1°C)
• Keep empty pans in the cabinet for better performance (there should be a pan at every level)
• Plug in unit one hour before service with door closed to allow pre-chill
• Load unit from bottom to top with PRE-CHILLED food at 40°F (4.4°C) or colder
• Ensure trays are pushed to the back wall
• Keep pans pushed toward the back wall as they are emptied, pull out and rotate 180 deg if needed
• Close door and allow inside temperature to stabilize to set temperature
• Unload cabinet from top to bottom
• Keep door closed and allow defrost cycle to complete (approximately 30 minutes)

The unit is equipped with an automatic condensate evaporator. To prevent water spills, leave unit plugged in with door closed after use. Aladdin recommends a defrosting after each use. Elevated internal cabinet temperature indicates defrost cycle is required.

Manual defrost:
To start or stop a defrost cycle press and hold “def” for 5 seconds

During open door operation, your RAC10 unit knows when the door is open and will not go into an auto or timed defrost cycle. Instead, the defrost icon will blink, letting you know that defrost will occur upon the door closing.’

CLEANING / MAINTENANCE

WARNING Risk of electrical shock. Disconnect electrical power supply before cleaning any parts of the unit or prior to any service.

Cleaning the condenser
The most important thing you can do to ensure a long, reliable service life of your RAC10 unit is to regularly clean the condenser coil. The condensing unit requires regular scheduled cleaning to keep the finned condenser coil clean of lint and dust accumulation. Keeping the condenser clean allows the cabinet to operate efficiently, use less energy, and achieve top performance.

To clean the condenser, first disconnect the electrical power to the cabinet and remove the front louver assembly. To remove the front louver panel simply pull the assembly down and out, the louver assembly is held in place with magnets. This gives complete access to the front of the condenser. Vacuum any dirt, lint, or dust from the finned condenser coil, compressor and other cooling system parts. If significant dirt is clogging the condenser fins (take care not to bend any of the condenser fins as this will reduce performance and compressor life), use a soft brush or compressed air to blow this clear. Replace panel, plug in unit, and turn back on.

Stainless steel cleaning guide

Stainless steel should be cleaned with warm water, mild soap and a soft cloth. Apply with a damp cloth and wipe in the direction of the metal grain. A stainless steel polish may be used to renew and protect the finish.
Do not use gritty or abrasive cleaners as they may tend to mark and scratch the surface.
Do NOT use cleansers containing chlorine, this may promote corrosion of the stainless steel.
Check the ingredients of any cleaning solutions or disinfectants used as they may contain chlorinated solvents which may cause a chemical reaction with the stainless steel. This could damage the surface and cause rusting.
Care should also be taken to avoid splashing the unit with water containing chlorinated cleansers when mopping the floor around the unit.
For stubborn odors, use baking soda and water (Ratio: 1 TBSP soda to 1 pint water). Unit must be cleaned with warm water to remove any baking soda residue.

Interior cleaning

For routine cleaning, it is not necessary to remove the interior side panels (left and right side). These panels are critical to the performance of the air curtain.
Door gaskets may be cleaned with baking soda. The door gasket is removable for cleaning when necessary.
Side panels should be removed to clean any major spills that flow behind the panels.

Removing the side panels.
Make sure all sheet pans are out of the unit. Remove the 5/16” hex bolt in the top air deflector, then remove the top air deflector. Then reach into the unit and rotate the panel lock bracket 90 degrees from the wall. You can now push the side panel back and pull away from the wall.

Routine visual check

Inspect door gaskets. They should
“snap”against door jamb before closure is complete. Visually check that the gaskets are sealed in their retainers and inspect for wear and tear. Replace if gaskets are torn or broken.
Inspect bumpers for damage or wear. Inspect cord for damage or wear.

Remove any debris such as mop strings, hair and hair nets from casters and replace when tread is 1/4” thick or less.

Reverse door direction
The RAC10 has a universal door that the orientation can be changed in the field with alternate hinges (Right 11669, Left 11670).

1. Ensure the unit is empty and unplugged.
2. Lift the door off the hinges.
3. Move the universal hinge covers from one side to the other.
4. Remove the hinges from the door.
5. Bolt the new hinges on the door.
6. Switch locations of the magnet and bolts on the inside of the door.
7. Lift the door back onto the unit.
