What are the grounding instructions for the cabinet?

This appliance is equipped with a cord having a grounding wire with a grounding plug which must be plugged into an outlet that is properly installed and grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current.

WARNING—Improper use of the grounding can result in a risk of electric shock. Consult a qualified electrician or service agent if the grounding instructions are not completely understood, or if doubt exists as to whether the appliance is properly grounded.

If necessary, contact a licensed electrician to install an appropriate 15 amp electrical circuit with the correct NEMA receptacle for the heater. DO NOT use an extension cord.

The ground prong of the power cord is part of a system designed to protect you from electric shock in the event of internal damage. DO NOT cut off the large round ground prong or twist a blade to fit an existing receptacle.

What should I do to start up the cabinet?

1. Prior to use, thoroughly clean the interior of the unit, according to the instructions in this manual.
2. Plug the power cord of the cabinet into a grounded outlet with electrical service according to the electrical information provided. Set the POWER switch to the “ON” position.
3. Do not load the product into the cabinet. Allow the heat to remove any residual oils which may adhere to inside metal surfaces. A slight emission of vapor is common during the first few hours of operation.

---

What are the steps for operating the cabinet?

1. Turn the power switch ON and let the cabinet preheat for 30 minutes. When the cabinet is turned on, the air heater will operate until the cabinet reaches the air temperature setpoint. The display will read the actual temperature.
2. To view the temperature setpoint, press and release the SET key.
3. After preheat, load the cabinet with food product. Food is held in various pan sizes as indicated by the spacing of the wire racks inside the cabinet.
4. When the cabinet is not in use, turn the power off.
5. The cabinet must be cleaned daily. See cleaning instructions.

What are the daily cleaning procedures for the cabinet?

1. After all food products have been removed from the cabinet, turn the power switch to “OFF” and allow the cabinet to cool. If the cabinet is supplied with a plug, disconnect from power prior to cleaning.
2. To remove the doors, first remove the front door by lifting the door up and out of the track. Then remove the metal door divider track that is located between the doors. Lastly, lift the rear door up and out of the track. Doors should be washed with a clean damp cloth and chlorine-free detergent. Rinse thoroughly with a clean damp cloth and allow to dry. Do not use scratch pads, abrasive cleaners, waxes, car polish, or substances containing strong aromatic solvents or alcohol. Do not use scratch pads or steel wool on the plastic doors. Do not use stainless steel cleaner.
3. Remove heat ducts by lifting up off of the rack posts and then sliding out. Using a clean damp cloth with appropriate cleaner (see page 9), clean the inside of the unit and the removed parts. Wipe any residue with a clean damp cloth. Reinstall all parts when they are dry and clean.
4. Inspect and clean the areas where there are vents or filters, making sure no water gets into the internal controls or electrical areas of the cabinet.
5. The controller should be washed with a clean damp cloth and chlorine-free detergent. Rinse thoroughly with a clean damp cloth and allow to dry.

What should I check if the Dixell temperature controller display is not lit?

• Switch is not in ON position: Turn the switch ON.
• Unit is not plugged in: Plug in the power cord.
• Circuit breaker tripped: Reset the circuit breaker. If it trips again, disconnect the EVO heater and reset once more. When it trips, call an electrician to replace the breaker or replace the feeder. Otherwise, investigate for a short in the heater. Test: 1. Heating element A. 208V – 18 Ω B. 240V – 24Ω Replace if the difference is significant. 2. Bower motor—replace if necessary. Advice: When testing the motor, please pay attention to: body temperature (may be very hot!), rotor side wobbling, jammed rotor, partial or complete winding shortage.
• Power cord or plug is defective: Replace or repair.
• Main switch is defective: Replace it.

What should I check if the Dixell temperature controller display is not lit, but the cooling fan is running?

• Defective thermostat Dixell: Check wires for crimping or looseness—correct if necessary.
• Check wire connection on thermostat terminals #5 and #6—correct connection or replace the thermostat.

What should I check if the Dixell temperature controller display is lit, but the food chamber is not heated?

• Heating element is cold:
  1. Check wires for crimping or loose connection—correct if necessary.
  2. Check wire connections on Dixell temperature controller terminals #8 and #9—correct loose connection.
  3. Check Dixell temperature controller—replace if necessary.
  4. Check Hi Limit 350°F—correct connection or replace Hi Limit if necessary.
  5. Check heating element (see above) – replace the element if defective.
  6. Check Hi Limit 160°F. If the Hi Limit reset button has popped up, figure out the reason, repair and reset.

---

What should I check if the heating element is hot?

1. Blower fan is loose—tighten set screw or replace.

2. Check blower motor:

   • Motor is very hot: overheat protection activated; figure out why the motor has overheated, correct it, cool down motor. Replace if the motor is faulty.
   • Motor is cold: correct connections or replace motor or capacitor if necessary.

---

What should I check if the Dixell temperature controller display is lit up and the food chamber is overheated?

• Heating element is hot:
  1. Hi limit 350°F is always closed: measure temperature on its surface; replace Hi Limit if it is hotter than 325°F. NOTE: When the cover is open, the wire compartment, including the Hi Limit 350°F is naturally cooled.
  2. Dixell temperature controller is defective; replace the controller.

---

What should I check if the cooling fan does not operate?

1. Check Hi Limit 120°F—replace if necessary.
2. Check cooling fan—replace if necessary.

NOTE: The fan is controlled by Hi Limit of 120°F and starts when the temperature in the wire box is higher than 120°F. This can take up to 6 minutes. Also, the fan might run after turning the switch OFF, until the temperature falls under 120°F.

---

What should I check if there is no heat and the heater blower is not running, and the heating element is not energized?

1. Remove cover, press Hi Limit reset button on “FAN SAFETY” limit.
2. Check operation of heater blower; replace if necessary.

NOTE: This Hi Limit prevents an “over temp” situation INSIDE the control unit and ensures proper airflow throughout heater and cooling fan operation.
