SET UP Carefully uncrate the unit. Re m ove all loose packing m ate ri a l, m a king sure that no small parts or acce s s o ries a re lost. I n s pe ct the unit for co n cealed damage be fo re d i s ca rding the packing mate ri a l. Operation NOTE: It is the responsibility of the installer to comply with all local codes. IMPORTANT: The hot and cold controls are factory set. Never attempt to change these settings. All control setting changes must be performed by a qualified technician. The unit is now re a dy for use. It is impo rt a nt that at l e a s t 1 2 of open airspace be maintained at the louve red panels. I m p ro per air flow thru the re f ri g e ration co m p ressor ca n lead to inadequate coo l i n g, ove rh e ating and damage to the co m p re s s o r. Such a condition will void the wa rra nty. The basic operation of the MOC20 is a dual compartment cart that holds pre-plated meals on hot and cold trays. This unit is designed for hospital/health care food service operations that use cook-serve meal preparation. The MOC20 is independently powered, meaning that it is not a static cart and plugs in to any 120vac single phase, 20 amp (NEMA 5-20R) dedicated receptacle. The MOC20 uses separate sides to maintain hot and cold food temperatures via gentle convection heating and a built in refrigeration system. It accomplishes this by using heated forced air via a blower/heated coil system and forced cool air via the Simplicool/Danfoss refrigeration system. 1. To start the unit, simply plug it into a 120 VAC 20 amp dedicated receptacle. Since the unit draws 15.5 amps at startup, a dedicated receptacle is required. 2. Close the doors and allow the unit to precool and preheat for 20 minutes. Next, load the trays of food into the cart. Keep the doors closed as much as possible. Door(s) left open for extended periods of time will greatly affect food temperatures. 3.The refrigeration system is design to operate for 30 minutes and then automatically go into a 5 minute defrost. During the 5 minute defrost cycle, the compressor shuts down. Thus when looking at the thermometers located on the side of the unit, temperatures will rise to approximately 210/215 degrees F. on the hot side and up to approximately 55 degrees F. on the cold side. Once the defrost ends, the temperatures will level out in approximately 10 minutes.this fluctuation does not affect food temperatures. Page 2

3 CLEANING INSTRUCTIONS WARNING: Never spray or pressure wash this equipment. Such action can cause damage to the electrical component, could cause serious electrical shock and will completely void the equipment warranty. WARNING: Cleansers, detergents, sanitizers or bleaching agents that contain chlorides or phosphates will cause permanent damage to stainless steel and aluminum products. The damage can appear as pits, severe discoloration, dulling of the finish and rust on stainless steel.this damage is permanent and will void the equipment warranty. Prior to cleaning, unplug the cabinet from the electrical power source. Using a mild soap and water, or other cleaners or sanitizers approved for stainless steel, wipe down the interior and exterior of the unit. This mild solution can be used as well on the center wall silicone rubber air dams/wipers. Do not use excessive water. Once clean, wipe dry with a soft cloth. Troubleshooting 1. General Safety and trouble shooting tips: a. Safety: When troubleshooting unit, make sure to disconnect the unit from the electrical power source. Do this by unplugging the unit from the 120 Volts, AC power source. Once the panels have been removed, a qualified & trained technician can electrically energize the unit for troubleshooting purposes. b. Also, at the terminal block, check for intermittent contact that occurs when a wire of a thicker gauge contacts an adjoining wire that is on a different circuit. Check for integrity of electrical wiring and connections. Check to see that all fork or ring terminals are tight on terminal board, heater and relay. Also check for intermittent contact made if a wire of thicker gauge is next to the wire in question. Check for tightness of wire nuts and all other electrical connections. Check electrical wiring for chafing and insulation tears. IMPORTANT: There are hot and cold air discharge openings located in the center of the inter compartments. There are also return air holes located on each side of the inter compartment. Never allow water and cleaning solutions to enter these openings. If this occurs, the moisture will damage the internal electrical components and void the warranty. 2. Unit is not Heating: NOTE: If the unit is heating, but not at its maximum performance level, check the return vent holes located on the inside side panels. The five (5) return holes located toward the center of the cabinet must be plugged. See RETURN AIR VENTS (HOT & COLD) on page 7 of this manual. ELECTRICAL AND REFRIGERATION SPECIFICATIONS Electrical: 120 VAC 1 phase 15.5 amps. Dedicated receptacle required. Refrigeration: R134A Freon, charge is 10.5 ounces, high side pressure is 197 psig & low side pressure is 104 psig. Mo nt h l y, check the condition of the co m p ressor filter and clean as needed. No te that a dirty filter will affe ct the pe r- fo rm a n ce of the re f ri g e ration sys te m, cause damage to the co m p ressor and may void the equipment wa rra nty. For f i l ter access and cleaning instru ct i o n s, re fer to the Ac cessing and cleaning of the Fi l te r s e ction in this manual. Maintenance IMPORTANT: This procedure is not covered under warranty and is the responsibility of the facilities maintenance/ engineering department. Such procedure must be performed by a qualified technician. a. If unit is not heating and all wiring is determined to be in good order: First, note whether the unit is heating up to 160 F. This should take about 30 minutes and can be verified by placing a thermocouple or thermometer in the bottom of the heated compartment. The thermometer or thermocouples should read 140 F -160 F. If not: b. Check to see if the 3300 Cal controller is reading 160 F. If not, reprogram the controller. This controller is located inside a lower access panel. Note that when the controller is operating properly, the temperature display will read 157 to 167 F. Also, there will be a flashing LED apparent on the left hand corner of the controller. If programmed properly: c. Check to see if relay is energized. If so, go to next step. Check for mechanical binding or chattering (usually repetitive). If so then replace relay. Please note that the controller circuitry has a certain amount of capacitance, meaning that there is enough charge to hold the NO (normally open) set of contacts on the relay closed until such time that the controller de-energizes (approximately 160 F). Thus, if checking the relay with an ohm meter, the contacts should show continuity, or if checking while electrically energized, there should be 120 volts across the terminals. This will hold true until the Cal 3300 controller senses a temperature of approximately 160 F. However, since the unit has a heating issue, at this point in the troubleshooting process, the Cal 3300 controller should not be showing this reading. Page 3

4 IMPORTANT: The following troubleshooting steps may require the removal of the Hot Box Assembly. NOTE: The Hi-Limit Thermostat, Hot Side Thermocouple and the Blower Assembly are all located in this box. See section Removal of the Hot Box Assembly on page 8 of this manual. d. Next, check the heating element: First, energize the unit and check the voltage across the heater terminals. If no voltage reading, check internal electrical wiring to the element. If there is 120 volts across the heater terminals, clamp an amp meter around one of the heating element lead wires. The heating element is rated 120 VAC, 1100 watts, thus, the amp meter should read approximately 9 amps. If not, replace the heating element. If so, the heating element is O.K.: e. Perform a continuity check on the hot side thermocouple.this thermocouple can be accessed at the Cal 3300 controller. If no continuity, replace the thermocouple. If O.K. f. Check the hi-limit thermostat for continuity. Since the unit is not heating, the hi-limit thermostat should be closed. If not, replace it. Please note that this hi-limit thermostat is set to open at 300 F. Its sole purpose is to act as a safety device. If hi-limit is O.K.: g. Check blower assembly. See if motor is running. There should be some motor/blower wheel vibration. Also, an air flow should be felt from inside the heated compartment. If not, check for 120 volts at the motor. If there is not 120 volts, check internal wiring. If so, and the air flow does not seem to be adequate, if available, use an Anemometer to measure the air flow. To do this, remove the air plentum from inside the cabinet and check the air flow. The air flow should be from 700 to 900 FPM. If not, replace the blower assembly. 3. Unit Not Cooling: c. Determine if unit is performing the proper 30 minutes cool cycle, followed by a 5 minutes defrost cycle. After every 30 minutes, the unit will go into an automatic 5 minute defrost. During the 5 minute defrost cycle, the compressor shuts down. Thus, during this period, when looking at the thermometers located on the side of the unit, the hot temperature will rise to approximately 210/215 degrees F. During this period, the cold thermometer will rise to approximately 55 F. Once the defrost cycle ends, the hot & cold temperatures will level out in approximately 10 minutes. If cycling properly: d. Check the continuity of the cold Side Thermistor at the Danfoss control. If no continuity, replace the Thermistor. To do this, the complete Simplicool refrigeration unit will have to be removed from the cabinet. See: Simplicool Refrigeration Unit Change Our Instructions on page 5 of this manual. Once the Simplicool system has been removed, see section Replacemant of Danfoss Cold Thermistor on Page 7 of this manual. If O.K.: e. Check the Danfoss control to make sure that it is at the proper setting. See Danfoss Control Location and Setting section on page 7 of this manual. To properly set the Danfoss control, turn the stem clockwise as far as it will go. If O.K.: f. Check the seal between the Simplicool refrigeration unit and the cabinet. There must be a good seal between the Simplicool unit and the cabinet bottom. First make sure that the Simplicool refrigeration unit is sitting properly on the support pedestals with Split Washers and that the Rear Retainer bracket is in place. See section Simplicool Refrigeration Unit Change Out Instructions on page 5 and refer specifically to figures 1, 2 & 5. g. Check the operation of the Simplicool refrigeration unit. If faulty, it can not be repaired. Contact Dinex for a replacement unit. If under warranty, the faulty unit can be exchanged for a new one. For out of warranty units, a new unit can be purchased and a partial credit given for the return of the failed unit.to replace the unit, refer to the Simplicool Refrigeration Unit Change Out Instructions on page 5 of this manual. a. Make sure that all of the electrical wiring is in order; next make sure that there is approximately 12 of open air space at the louvered panels located in the lower portion of the cabinet. Improper air flow thru the louvered panels can cause improper cooling. This condition can also cause overheating of the compressor and void the equipment warranty. If there is proper air space: b. Check to see if the filter located behind one of the louvered panels is dirty. To access the filter see section Accessing and Cleaning of the Compressor Filter on page 5 of this manual. Please note that the cleaning of the air filter is not covered under warranty. If filter is clean: Page 4

5 ACCESSING AND CLEANING OF THE COMPRESSOR FILTER SIMPLICOOL REFRIGERATION UNIT CHANGE OUT INSTRUCTIONS 1. Disconnect electrical power to the refrigeration unit by unplugging the unit. 2. Remove all three (3) access panels located at the bottom of the unit. 3. Remove the filter, filter housing and foam baffles from the sides of the refrigeration unit. These are attached with Velcro strips which are located on both sides of the opening. Rear retainer bracket IMPORTANT: The filter is to be inspected monthly for a build up of dust and dirt. A dirty filter will greatly affect the cooling capabilities of the unit. A dirty filter can also cause damage to the compressor thus voiding the warranty. Cleaning of the filter is not covered under warranty. However, this procedure must be performed by a qualified person. 1. Important: Disconnect electrical power to the unit by unplugging it Figure 1 2. Remove the louvered panels located on the door side of the unit. 3. Remove filter: Filter is held in place with Velcro strips. Clean filter by vacuuming or with compressed air. If compressed air is used, take the filter to an isolated area away from food product and other employees. It is recommended that eye protection always be used. 4. Once the filter is clean, install the filter as well as the louvered panels. Split washers Frame support pedestal Figure 2 Page 5

Remove the rear retainer bracket by removing two (2) bolts & nuts. This bracket keeps the refrigeration unit from sliding out the side opening (See figure 1). 6. Next, l ocate the two frame suppo rt pe d e s t a l s. Re m ove Only the two top scre ws as shown in Fi g u re 2.The bo t tom bo l t, one per frame suppo rt pedestal can be loosened as show n in Fi g u re Using a long scre wd ri ver or bar, p ry up on the bo t tom of the re f ri g e ration unit. Now the bo t tom bolts on the frame suppo rt pedestals can be re m oved (See figure 3). Re m ove the f rame suppo rt pe d e s t a l s. It is impo rt a nt to note that split washers will also be re m oved with the frame suppo rt pe d e s t a l s. Figure 4 8. Slide refrigeration unit out. Pry up and remove frame support pedestals and split washers. This gasket is not glued on. It is to be Installed in the forward position. The large gasket is adhered to the bottom of the cart with 3m 90 adhesive. Figure 5 Figure 3 9. Replace the refrigeration unit by reversing the steps listed above. However, it is very important that the replacement unit be installed properly so the there is a good seal between the cabinet inlet port as well as the return air ports. If a good seal is not acquired, the cabinet will not maintain cold temperatures. There are two gaskets (See figure 5).The larger one is adhered to the bottom of the cabinet with 3M #90 adhesive. Never adhere/glue this large gasket to the refrigeration unit. The smaller rectangle gasket is to be placed in the refrigeration unit rectangular inset as shown above. This gasket must be located as close to the 3 air return openings as possible. Do not glue this gasket in place. Page 6

7 Lift Center Partition Up to Remove and Install Cold Thermocouple. Figure It is extremely important that both the support pedestals and all of the split washers be installed. It is equally important that the rear retainer bracket be bolted properly in place. To assist with the proper installation, it is recommended that a wooden pry bar be used as shown in Figure 6. This will allow for enough upward force to be applied while the rear retainer brackets and split washers are installed. Also, being wood, the pry bar will not puncture or damage the refrigeration unit. When installing the new thermistor, route it thru the bottom corner of the partition. It is critical that once the new thermistor is installed that these two surfaces be even/flush. NOTE: Above, it is critical that the new thermistor be routed under the center partition on the same path as from which the faulty thermistor was removed. When installing the slide out partition, the top surface of the partition must be flush/even with the permanent position. DANFOSS CONTROL LOCATION AND SETTING REPLACEMENT OF DANFOSS COLD THERMISTOR O n ce the Si m p l i cool unit has been re m oved from the ca b i n e t, re m ove the top & one side of the unit by re m oving 4 faste n e r s. Turn the Danfoss Stem clockwise as far as it will go. This is the proper setting.
