SAFETY INFORMATION
WARNING: Follow all food safety guidelines. Pre-heat the cabinet to the desired temperature before placing hot cooked
food into the cabinet. Food must be at the appropriate temperature before being placed into 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: This cabinet is for hot food holding applications only.
WARNING: Unplug the cabinet before cleaning or servicing. Do not wash the cabinet with a water jet or high pressure
water, do not hose wash/spray interior.
WARNING: Allow the unit to cool before cleaning, as the interior of the cabinet may be hot enough to burn.
WARNING: Food Service Equipment must be electrically grounded. Failure to ground Food Service Equipment may
result in serious injury or death from electrical malfunction.
CAUTION: Never steam clean. Severe damage or electrical hazard could result.
CAUTION: Water dripping onto the oor from open doors can be a slip hazard.
For future reference, note the serial and model number found on the data plate of the cabinet here:

OPERATING INSTRUCTIONS
A. SLIDE RACKS
The slide racks provided with your cabinet are nickel chrome-plated to insure years of corrosion-free service. The
racks are already in place when the cabinet is shipped to you. They can be removed for cleaning by first lifting up on
the rack and then swinging the bottom towards the center of the cabinet.
The slide spacing is 25/8" to accommodate lip loaded pans for TC90S; bottom loaded pans for TC90B.
The following pans may be used:
9 pans — 12" x 20" x 21/4" (TC90S)
9 pans — 12" x 20" x 25/8" (TC90S)
9 pans — 18" x 26" x 1" (TC90B)
B. CABINET START-UP
1. A nine-foot, three-wire grounded lead cord is supplied fi xed to the cabinet. The cord cannot be separated from
the cabinet.
NOTE: Before operating your cabinet be sure to unwrap the lead cord completely from bracket.
CAUTION: With the POWER switch OFF, plug the lead cord into a standard grounded 15-amp, 125-VAC receptacle.
2. Set the thermostat dial to setting 10 = HIGH.
3. Snap the POWER switch to ON. The red POWER light will now glow as will the yellow indicator light indicating that
power is on and that the heating elements are activated and heating up.
4. Allow the cabinet to PREHEAT FOR APPROXIMATELY 45 MINUTES. After that time, the thermostat can be lowered
to a setting of 6 or 7. In a room of average temperature (72°F), this should provide 150°F to 170°F. Adjustments to
the temperature may be made as necessary.
NOTE: The POWER (red) light will glow as soon as the POWER switch is switched ON and will continue to glow
until switched OFF. The yellow indicator light will go on and off as the thermostat cycles. If the yellow light is not
illuminated, this indicates that the cabinet has achieved the preset TEMPERATURE level, NOT that the unit has been
switched OFF.
It is not necessary at the end of the operating day to disrupt the temperature setting in order to turn the unit OFF. By
switching the POWER switch to OFF, the unit is no longer operating.
By switching the POWER switch to ON when resuming operations, the cabinet will attain the preset level.

CLEANING INSTRUCTIONS
Before proceeding with any CLEANING activity strictly follow “Safety Information” on page
2 of this manual.
ALL MODELS
Your TC90 series cabinet has been listed by the National Sanitation Foundation (NSF) which means that it has been
designed and constructed in a way that promotes a sanitary condition, i.e. sanitary materials and easy cleanability. To
maintain a sanitary condition and obtain the best cabinet performance, Metro strongly suggests that the cabinet be
thoroughly cleaned on an adequate regular basis — daily if necessary.
A. REMOVAL OF INTERIOR COMPONENTS FOR CLEANING
All interior components are removable, without tools, for thorough, unobstructed cleaning.
1. Turn off master switch and disconnect the unit from its power source.
2. If necessary, the door may be removed by simply lifting it from its cabinet-mounted hinges. Do not place the door
against an object that may scratch the door or damage the gasket.
3. The slide racks may be removed by lifting them from their respective brackets.
4. After cleaning, simply reverse the above steps to reassemble the cabinet.
B. SPECIFIC CLEANING INSTRUCTIONS
Do not immerse the cabinet when cleaning. Instead, use a damp cloth and a drying towel. BE SURE TO
THOROUGHLY DRY THE UNIT BEFORE RETURNING IT TO USE.
C. GENERAL CLEANING INSTRUCTIONS
1. LIGHT SOIL: If routine (daily) cleaning is practiced, a mild soap and warm water should be suffi cient to keep the
unit clean.
2. HEAVIER SOIL: If cleaning has been postponed, solvent or emulsion type cleaners that can be applied with bare
hands will give excellent results. Such cleaners are available under various brand names and detergent suppliers
can recommend materials appropriate for use on natural and epoxycoated aluminum and stainless steel interior
liner.
NOTE: For every cleaning method, best results are always obtained when the cleaner and technique are matched to the
soil conditions involved. To ensure using the proper cleaner for natural and epoxy-coated aluminum and stainless steel,
contact your detergent representative.
CARE AND MAINTENANCE
Before proceeding with any CLEANING activity strictly follow “Safety Information” on page
2 of this manual.
A. CABINET MAINTENANCE—ALL MODELS
Your TC90 series cabinet has been designed to require very little maintenance. With normal use, cleaning is the only
form of maintenance that need be done on a regular basis. Keeping the casters free of dirt build-up will go a long
way in prolonging their life.
If your cabinet is rolled over rough surfaces or transported over-the-road, the various threaded fasteners, i.e., screws
and nuts, should be periodically inspected and tightened if necessary, particularly the transport latch, hinge and
caster fasteners.
B. CONTROL PANEL MAINTENANCE
The control panel of your cabinet has also been designed to require very little maintenance. With normal use,
cleaning is the only form of maintenance that need be done on a regular basis. No maintenance is required on the
electrical components.
