CLEANING

WARNING: ELECTRIC SHOCK HAZARD Unplug the unit from electric power before performing cleaning or maintenance.
WARNING: BURN HAZARD Allow the unit to cool before performing any cleaning or maintenance procedures.
WARNING: ELECTRIC SHOCK HAZARD DO NOT spray or splash water on the heater, control panel, timer, or wiring.
CAUTION: CART DAMAGE Do not tip the cart onto the doors to drain excess water. Permanent damage to the doors and hinges will result. Use a clean dry cloth to mop any excess water inside the cabinet after cleaning.
Turn the main power switch OFF, unplug and allow the unit to cool before cleaning. Remove the THL heating unit; simply lift up and off the top of the cabinet. DO NOT spray or splash water on the heater, control panel, timer, or wiring.

1. Racks or shelves are easily removed without tools for cleaning, Simply lift up and pull out. The tray racks may be hand-washed or run through an automatic washer.
2. To clean stainless steel surfaces use only cleansers, detergents, degreasers, or sanitizers that are certified to be “chloride-free” and “phosphate-free,” and cleansers, degreasers, or sanitizers only in the recommended concentrations. DO NOT exceed recommended concentrations or mixing ratios. After cleaning and sanitizing, rinse all exposed surfaces thoroughly with large amounts of clean, clear water. Wipe off any standing liquid or residue from all surfaces, corners, and rear edges.
3. Vinyl trim should be washed with a chlorine-free detergent and water. Rinse thoroughly with clear water and allow to dry. Never use abrasive cleaners, waxes, car polish, or substances containing strong aromatic solvents or alcohol. Use of direct steam / hot water cleaning at temperatures above 190°F may result in “bubbling” or loosening of vinyl adhesive.
4. After all, parts are dry, reinstall them and then replace the heating unit.

IMPORTANT: Cleansers, detergents, degreasers, sanitizers, or bleaching agents that contain chlorides or phosphates will cause permanent damage to stainless steel products. This damage appears as pits, eruptions, voids, small holes, cracks, severe discolorations, or the metal finish’s dullness. Water with a high chlorine content can also damage stainless steel. If unsure of your water quality, we recommend you have it tested. THIS DAMAGE IS PERMANENT, COSTLY TO REPAIR, AND IS NOT COVERED BY WARRANTY.
RECOMMENDED “TIPS” FOR CLEANING STAINLESS STEEL

PURPOSE

| FREQUENCY| CLEANING AGENT|

DAILY OPERATION

CAUTION: SAFE FOOD HOLDING PRACTICES RECOMMENDED Cooking food to a safe temperature, holding at a temperature of at least 140°F is critical in the prevention of foodborne illness. Hold only cooked, hot food at 140°F or higher. This cabinet is not intended to cook or reheat food. Food must be at an appropriate temperature before being placed into the cabinet.
WARNING: FOR EQUAHEAT BANQUET CARTS EquaHeat Banquet carts are equipped with canned fuel drawers at the base of the door(s). If you are using canned fuel (i.e. Sterno™), do not operate the heating system at the same time. Temperatures will get too high for proper food holding.

1. Plug the heater into a proven power source. The white indicator lamp and the fan will operate continuously whenever the heater is plugged in.
2. Turn the thermostat to number 4 or 5 on the knob. Be sure the cabinet door(s) are fully closed during the pre-heat time.
3. Food serving temperature will vary with the mass, type, and quantity of food being held. Set the thermostat for the desired holding setting. Turn clockwise to increase the temperature and counter-clockwise to decrease the temperature.
4. During loading, the cabinet temperature will drop. Close the door and wait 10-15 minutes for the cabinet to recover the air temperature before disconnecting from the power source.
5. Be sure to remove the plug from the outlet and wind the cord on the cord bracket or push the handle before moving the cart. Move the cart to the service area as quickly as possible.
6. Upon reaching the service area, unwind the power cord and reconnect the heater as quickly as possible. Wait 10-15 minutes (check the thermometer to see if the temperature is are the desired level). If not adjust the thermostat as required.
7. When removing the product from the cart, start at the bottom and work to the top position. This keeps food hotter and eliminates spillage onto lower items.

NOTE: BB series EquaHeat Banquet carts have drawers for canned fuel at the base of the cabinet. Cut-outs indicate where canned fuel should be inserted into the drawers. Do not operate the electric heating system at the same time you are using canned fuel or exceed the capacity of canned fuel (2 per door). Using more than the recommended quantity will result in temperatures that are too high for proper holding.

CALIBRATIONS

THERMOSTAT CALIBRATION If additional heat range is required in the heating unit, remove the thermostat knob, insert a small straight-blade screwdriver into the opening and turn the limit control set screw counter- clockwise one full turn. Replace the thermostat knob and turn it clockwise to reach the new maximum temperature. Repeat this until the desired temperature is reached. Each 1/4 turn of the calibration set screw will raise the element heating capacity by approximately 25°F to 35°F (4°C to 7°C).
THERMOMETER CALIBRATION
If a reduction of heat is desired, turn limit control set screw clockwise one full turn. Hold the door open and allow the unit to cool until the inside temperature is below the temperature desired. Close the door and allow the unit to rise to the new maximum temperature. Repeat until the desired temperature is reached.
Place an oven thermometer in the center of the cabinet. Turn the heater on; turn the thermostat to the maximum setting and wait approximately 45 minutes. Open the door and check the inside thermometer temperature. If recalibration is required, pry the plastic cover off the dial body, and with a small flat blade screwdriver, insert it into the pointer as shown. Carefully turn the pointer with your finger to the correct setting. Be careful not to bend the pointer. It is very fragile.

MALFUNCTION LIGHT

GENERAL MAINTENANCE INSTRUCTIONS

CASTERS
Some casters are equipped with Zerk grease fittings so that they may be easily lubricated with a grease gun. Recommended lubrication is at least once every six months.  Lubrication will be required more frequently if carts are cleaned with hot water or a steam cleaning system. Casters with special bearings are recommended for frequent cart wash or steam cleaning situations.
LATCHES
Check frequently to insure that all door latches are secure. Latches may become “sticky” due to residue build-up from daily use and cleaning. Lubricate latches regularly with WD-40, silicone spray, graphite, or other commercial lubricants for stainless steel products. Do not use oil.
PERIMETER BUMPERS
Vinyl that has been dislodged from the channel due to severe bumping or scraping can be pried back into place with a common screwdriver.
