TIP: It is easier to start rail installation from the bottom and move up.
1. Using the chart on page 2, select the type of holding you would like to achieve. 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 and 13.
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 congure the other side.

Electrical Specifications
(Per Compartment)
For Electric Models:
1. From any PCU module, plug into 100-120 VAC (110v models) or 200-230VAC (220v models) 50/60 HZ electrical receptacle. Product label located on the heating or
cooling unit clearly indicates power requirements. Use ONLY power cords supplied by Cambro Manufacturing.
2. The red light on the switch for Hot modules indicates power ON, the amber light indicates active heating. This amber light will remain on until the heater reaches factory
set temperature of 150˚F to 165˚F (65,6˚C to 73,9˚C) and then will turn off. Power is activated on Cold modules by actuating the switch to the right of the AC power inlet.
The digital display will illuminate and display the temperature of the compartment.
NOTE: Hot module will switch on and off as necessary during operation to maintain factory set temperatures. Cold modules will also cycle on and off as it reaches the
set temperature set by the user.
3. On Cold Module operation: place the back or handle side of the cart at least 6" (15,2 cm) away from any wall or large items to promote good airow.
Temperature performance of the Cold Modules may be reduced if airow is poor.
Pre-chill the compartment(s) empty with door(s) closed for at least 90 minutes (depending on ambient temperature) before loading with cold food.
4. On Hot Module operation: empty with door(s) closed for 45 minutes to 1 hour prior to loading hot food.
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.
DO NOT push trays all the way into the compartment as this can interrupt air ow and impede performance.
TIP: 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.
5. When transporting the cart, always remove the power cord(s), store the power cord(s) in the holding straps located on the back of the cart,
prior to moving it.
6. Insulated PCU carts will hold food at safe temperatures for 4+ hours unplugged*. (see charts on next page)

V. Operating Instructions for Electric Use (continued)
For best operating results, the Pro Cart Ultra™Passive holding carts should ideally be pre-heated or pre-chilled for at least
20 to 30 minutes before loading with food.
For holding hot food:
Pre-heat each empty cabinet by sliding a full-sized food pan lled with hot water onto the bottom rails. Close the cabinet door.
OR Simply place one or two Camwarmers®(1210PW - heated in the oven at 350˚F for 45 minutes) on a sheet pan and place onto
the bottom rails and close the cabinet door. Camwarmers®can remain in the cart to extend the holding time of hot foods beyond 4 hours.
For holding cold food:
Pre-chill each empty cabinet by sliding a full-sized food pan lled with ice water onto the top rails. Close the cabinet door.
OR Simply slide one or two Camchillers®(CP1220 - frozen at for 8 hours) to the top of the compartment and close the cabinet door.
Camchillers®can remain in the cart to extend the holding time of cold foods beyond 4 hours.

Instructions for Resetting Heaters
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 rmly 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 gure 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.
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).
Cleaning Modules
RESET
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.
VII. Care and Maintenance
TIP! Before removing any modules, put the cart's brakes on.
1. Carefully remove SS screws and washers from heater with one hand while holding heater with your other hand.
CAUTION! Once you start loosening the screws, the heater may fall unless you are rmly holding it.
2. Clean components and module with a moist soft cloth and mild detergent to remove any remaining dirt.
3. Completely air dry all components or wipe with dry, clean soft cloth before re-assembling and using.
4. 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.
5. Use SS screws and washers to re-attach the heater to the module. Tighten the screws rmly but not
excessively. Do not use tools other than a #3 Phillips screwdriver. During normal operation, periodically
check screws for tightness.
6. Inspect plug blades and cord, replace power cord if frayed or blades or prongs are missing, bent or broken.

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
ll 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 ts 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.
VII. Care and Maintenance (continued)
Warning! Hazard of Electric Shock — Disconnect power supply before servicing. Any operating problems not identied and corrected by instructions in this manual should be
referred to qualied service personnel (electrician or foodservice equipment technician). No user-serviceable items under the inner cover of the electrical units. Only qualied
service personnel should open the inner cover of any electrical device.
