1.  With the POWER switch OFF, plug the supply power cord into an appropriate, 
grounded, receptacle. (Refer to the cabinet data plate for voltage and 
ampere rating).

2.  Fill the water reservoir in the floor of the cabinet with clean warm water. 
The capacity of the reservoir is about 41/2 U.S. Gallons (17 liters). The water 
level should be no higher than 1/2 inch (13mm) below the bottom of the water 
reservoir cover.

3.  Ensure that the water reservoir cover is installed (refer to the cabinet operating 
instructions). This is required for the cabinet to function properly.

  4.  Set the POWER switch to the ON position.

5.  The cabinet will initially display current temperature and humidity set points and 
then show the actual cabinet temperature and humidity.

6.  The temperature and humidity displays will continue to blink until the 
temperature set point is reached.

7.  To change temperature or humidity set points, turn a control knob. As a knob is 
turned, the temperature and humidity display will show the set points, and the 
“F° and C°” indicator lamps will blink. About 3 seconds after a knob is turned, 
the display will show the actual cabinet temperature and humidity.

8.  Press and release “Recall Set Points” button to see the current cabinet 
temperature and humidity set points.

9.  To see the current alarm set point, press and release “Low Temp Alarm” button. 
To change the alarm set point, press and hold “Low Temp Alarm” button, turn 
the temperature knob to the desired setting, and release button.

10.  To clean cabinet, turn power off, unplug from wall outlet, allow cabinet to 
cool, wipe with a damp cloth and dry with a towel. Floor of cabinet and water 
reservoir may be rinsed out with a low pressure hose.

11.  Consult the user manual for additional operation and maintenance information.

SAFETY INFORMATION

WARNING: Follow all food safety guidelines. Pre-heat the cabinet to the desired temperature before placing

cooked, hot food into the cabinet. This is not a re-thermalizing cabinet. Food must be at the
appropriate temperature before being placed into this cabinet. Use a food probe to check internal food
temperature — the cabinet temperature is not necessarily the internal food temperature.

WARNING: Only factory approved service agents should attempt to service, repair or replace electrical

components, wiring or power cord.

WARNING: Unplug the cabinet before cleaning or servicing. Do not wash the cabinet with a water jet or high

pressure water.

WARNING: This cabinet is only for hot food holding applications.

CAUTION: Do not spray or pour water into the top of the cabinet (control enclosure). To clean the cabinet, wipe

with a damp cloth and dry with a towel. Use only cleaning agents approved for stainless steel or
aluminum (depending on your cabinet construction). The floor of the cabinet and water reservoir may
be hosed out with low pressure water.

CAUTION: Water dripping onto the floor from open doors can be a slip hazard.

INSTALLATION AND SET-UP

1. Check for Shipping Damage: Check the packaging and cabinet for shipping damage before and after unloading
the unit, and after removing all the packaging.

2. The receiver of this product is responsible for filing freight damage claims. This equipment must be opened
immediately for inspection. All visible damage must be reported to the freight company within 48 hours and must
be noted on freight bill at the time of delivery.

3. Concealed damage is your responsibility — you must advise the carrier of any loss or damage within 15 days
after receipt of the cabinet. If there is damage, retain the original packaging for inspectors.

4. After unpacking the cabinet, remove all tape and packing material from the inside as well as outside of the unit.

5. Any protective covers (plastic or paper sheet) on the sheet metal or clear door(s), if applicable, must also be
removed before turning the cabinet on.

WARNING: Only factory approved service agents should attempt to service, repair or replace electrical

components, wiring or the power cord.

6. The power cord can be installed to exit the back
of the cabinet for wall outlets or out the top of the
cabinet for ceiling power drops. To change the
position of the power cord, first make sure the
cabinet power switch is off and the power cord is
unplugged from any electrical outlet. Remove the
(7) screws holding the cabinet top in place. Lift
the rear portion of the cabinet top and slide it

away from under the front control bezel, removing it from the cabinet. Remove the (2) screws on the rear of the

cabinet that hold the cord bracket in place. Rotate the power cord bracket 90° to the desired position and reattach
it with the (2) screws to the back of the cabinet. Make sure the green ground wire connection and the wire nuts on
the black and white wires have not loosened. Do not alter
the wiring of the power cord to the cabinet. Replace the
cabinet top and the (7) screws holding it in place.

7. Refer to the data plate located near the power cord for the
electrical specifications of cabinet. With the POWER switch
OFF, plug the cord into the appropriate rated, grounded
receptacle. Cabinets rated at 120V 2000W must be plugged into
125VAC 20 amp receptacle and must be used on an individual
branch circuit. Cabinets rated at 120V 1440W may be plugged
into either a 15 amp or 20 amp receptacle. Cabinets rated at 220-240V 1681-2000W must be plugged into a
250VAC, 15 amp receptacle.

8. The factory setting for temperature is Fahrenheit. To change the temperature display from Fahrenheit to Celsius a
jumper needs to be changed on the back of the controller circuit
board. Turn the cabinet off, unplug the cabinet from the electrical supply and remove the top of the cabinet (refer to
step #6). See the control wiring diagram below for the location
of jumper JP5. For Fahrenheit control, the jumper is on the
lower two pins. For Centigrade control, move the jumper from

the lower two pins to the upper

two pins. After changing
the jumper, replace the top,
plug the cabinet in, turn
the cabinet on and adjust

the temperature and low
temperature alarm settings
for the new units (°C or °F)

of temperature selected.

9. Your C5 cabinet is designed
to operate next to walls and
other kitchen equipment.
However, the greater the
clearance around the sides

and the top of the cabinet, the cooler the electrical components will operate. This may result in a longer life

expectancy for the electrical components.

REVERSING THE DOORS

 WARNING • TIP HAZARD

Tip Hazard: On Pass-Thru cabinets that include any clear doors, when field reversing, the front and back doors

must be hinged from opposite sides of the cabinet. See illustration below.

Clear Doors
Hinged on
opposite
sides of
the cabinet

After reversing the door hinging direction, labels are now
upside down. You may contact InterMetro for a new set
of labels, part number RPC5-DRLBL, at no charge, to be
placed in the proper orientation.

C5 doors are normally hinged on the right hand side at the factory. If the cabinet has been in operation, allow the
door to cool before reversing the door hinging direction. Note: When finished, all holes will have screws in them and
there will be no exposed holes left in the cabinet.

1. If the cabinet has Dutch Doors, note which is the top and which is the bottom door. Open the door, lift it off the
cabinet hinges and set it aside noting which is the top and bottom of the door.

2. On the cabinet, remove the latch strike plate and hinges and install them on the other side of the cabinet. On the
door, remove the hinge covers to access the mounting screws. Remove the hinges.

3. Rotate the door so the previous bottom is now the top and install the hinges. On Dutch Doors, do not remove the
handles, the top door becomes the bottom and the bottom door the top. On single door units, rotate the handles
180° and reinstall.

4. On the cabinet mounted hinges, lift the white bushing and rotate it 180° and push it down to reseat it on the
hinge pin.

5. Install the door onto the cabinet hinges and check to make sure the door latches properly and the gaskets
are in compression.
