Rail Installation and Capacity Guide

Before operating the cart, install rails based upon your facility’s needs.
Each cart ships standard with 5 pairs of rails per compartment. Save extra rails for future use.
TIP: It is easier to start rail installation from the bottom and move up.

1. Follow the number guides etched into the columns of the cart to place your sheet pan, food pan, tray or pizza box in the correct position. For example, to achieve standard capacity for full-sized sheet pans, place the rails at positions 1, 3, 5, 7, 9, 11, 13, and 15 (additional rails required).
2. Insert the top tabs into the front and corresponding middle and rear slots of the column.
3. Slide the rails towards the back of the cart then rotate it down into a nested position.
4. Install the subsequent rails into position following the appropriate numbering guide. Once the rails have been installed on one side of the cart, repeat instructions to configure the other side.
5. To install position 16, remove screw and bumper, remove side column, insert rail, slide column back in, replace screw and bumper. Repeat on other column.

Operating Instructions for Electric Use

NOTE: Units are designed to hold pre-heated hot food and pre-chilled cold food only. ALWAYS pre-heat or pre-chill unit. NEVER use to heat up or cool down food temperatures.
WARNING! Not intended for use outdoors. NEVER use in wet or damp conditions. Refer to Section II for Safety Instructions and Warnings. Hot Electric Models:

1. Plug unit into correct power outlet. Use ONLY power cords supplied by Cambro Manufacturing.
2. Switch on power button.
3. Pre-heat cabinet for 30 to 45 minutes before loading with hot food.
4. Load food.

NOTE: Hot module will switch on and off as necessary during operation to maintain factory set temperatures.
Tips to Maximize Performance
A. DO NOT load food over 190˚F (87,7˚C) as this can damage the compartment or trip the high limit protection on the heater.
B. Leave a gap in the back of the cart between the heater and the pan for good air flow and not to impede performance.
C. If hot food is being loaded into the cart directly from the oven, keep the door of the cart open until temperatures are near the 190˚F (87,7˚C) temperature.
This practice will help protect the cart, slow down any further cooking of the food and maximize hot food holding quality.
Cold Module Controller (setting the temperature)Cold module is factory set at 32.5˚F (0,28˚C) and can be adjusted up to 40˚F (4,4˚C)
Buttons on left have no function on this unit.
Cold Electric Models:**

1. Plug unit into correct power outlet. Use ONLY power cords supplied by Cambro Manufacturing.

2. Place the back of the cart at least 6″ (15,2 cm) away from any wall or large items to promote good airflow.
   Temperature performance of the Cold Modules may be reduced if airflow is poor.

3. Turn on power switch to the right of the AC power inlet. The digital display will illuminate and display the temperature of the compartment.

4. Set temperature between 32.5˚F and 40˚F, see Setting the Temperature.

5. Pre-chill cart for 90 minutes before loading food.

NOTE: Cold generation may cause condensation. Wipe up excess water.
NOTE: Cold modules will cycle on and off as the cabinet reaches the set temperature.
DO NOT use unit as a refrigerator. Turn off after 24 hours of continual usage.

Care and Maintenance

A. MODULES
WARNING! Completely cool heater unit prior to cleaning or maintenance.
WARNING! Do not submerge heater or cold module in water or spray water on it.
WARNING! Do not get the thermometer wet in any way.
WARNING! Unplug grounded power source from module prior to cleaning.
Care and Maintenance (continued)
Instructions for Resetting Heaters
NOTE: Normal operation of the heater is controlled by an automatic cycling “Control Thermostat.” Failure of the control thermostat may cause the temperature inside the compartment to rise to temperatures that could cause damage to the plastic.
A second, manually resettable “Hi-limit Thermostat,” is built into the heater circuit. This device will shut off power to the heater in the event the temperature in the cabinet reaches to 195˚F (90,6˚C). The heating unit will not return to normal operation until the reset button on the hi-limit thermostat is depressed. Other factors can cause the hi-limit thermostat to shut off power, such as fan failure or placing food pans inside the compartment with temperatures higher than 190˚F (87,8˚C).
CAUTION: Electrical Shock Hazard!
Before attempting to reset the hi-limit thermostat, unplug the heater power cord from the power source and from the heater.
WARNING! Only use “non-metal” tools to depress the reset button.
Do not bypass or alter the thermostats in any way.

1. Remove the power cord from the wall outlet or power supply and remove the other end from the front of the heater.

2. Open the door, reach into the compartment and hold the heater firmly while you remove the 5 SS screws with washers, holding the heater against the inner face of the module.

3. Place the heater on a stable surface with the metal section facing down.
   Locate the small round hole in the cover with the word RESET next to the hole.

4. Using a small diameter, round, non-metal item such as a rigid plastic stir stick or wooden skewer stick, guide it through the hole and depress the button on the hi-limit thermostat as seen in the figure below.
   NOTE: The Amber light will not be active when the high-limit thermostat has been tripped along with the loss of the heater element.

5. Remove the item you used to depress the button and re-attach the heater to the module with the screws and washers.

6. Plug the cord into the heater and then to the power source. Switch on the heater and verify it is heating up to the normal temperature.

Cleaning Modules
Modules should be cleaned when they look dirty or as part of a preventive maintenance schedule to ensure performance of the cart.
Place cart against a wall or have a helper hold the module in the back so it doesn’t fall.

1. Put the cart’s brakes on and make sure unit is unplugged.

2. From the inside of the cart, carefully remove 4 SS screws and washers at the corners from the module.

3. Gently push module from the inside and remove from cart.

4. Clean components and module with a moist soft cloth and mild detergent to remove dirt and grease.

5. Completely air dry all components or wipe with dry, clean soft cloth before re-assembling and using.

6. Carefully place heater into the recessed area of the inner face of the module. Align AC inlet for power connection with rectangular hole through the module.

7. Use 4 shorter SS screws and washers to re-attach the heater to the module. Tighten the screws firmly but not excessively.
   Do not use tools other than a #3 Phillips screwdriver.

8. Reinstall module to the cart with the 4 SS screws.

9. During normal operation, periodically check screws for tightness.

10. Inspect plug blades and cord, place cord If frayed or blades or prongs are missing bent or broken.

Cleaning Tip: Wipe up any spills as soon as possible. Clean cart regularly to avoid heavy dirt build up. Leave door open after use so cart can air out. Care and Maintenance (continued)
B. CART BODY

1. Clean with mild detergent, hot water and a soft cloth. DO NOT use detergents or cleaners containing ammonia or bleach.
2. Hand wash using a soft cloth or brush to clean all interior and exterior surfaces. DO NOT use steel wool or abrasive scrub pads or brushes.
3. Use a clean moist soft cloth to remove any remaining soap and dirt.
4. Air dry or dry cart outside and inside with clean, dry, soft cloth.

C. CASTERS
Caster bearings need to be lubricated with a high quality multi-purpose grease that has good extreme pressure and anti-wear characteristics, as well as withstands temperature range that fits the application requirements. Wheel and swivel bearings last longer if lubricated regularly. Some lube applied to friction points on the wheel hub, washer and leg surfaces of straight roller bearing systems reduces drag and improves reliability. Normal conditions may warrant lubrication every six months, but once a month may be necessary in extreme applications, such as corrosive or exceptionally dirty environments. Cart washings may necessitate lubrication after each wash.
