II. RECEIPT INSPECTION III. INSTALLATION (continued) All Traulsen products are factory tested for performance and are free from defects when shipped. The utmost care has been taken in crating this product to protect against damage in transit. All interior fittings have been carefully secured and the legs or casters are boxed and strapped inside to prevent damage. Door keys will be attached to the handle with a nylon strip. The handle is protected by an easily removable nylon netting. III.
III. INSTALLATION (continued) III. e - ROLL-IN MODEL INSTALLATION (cont’d): A stainless steel threshold ramp(s) is included to facilitate roll in racks. It is shipped wrapped in brown paper and secured to the rack guides inside the cabinet. To secure it in place, remove the two thumb screws in the breaker strip near the bottom door opening. Next, loosen the thumb screws located along the floor at the threshold.
III. INSTALLATION (continued) III. h - REMOTE INSTALLATION (cont’d): Refrigerant line installation must be done in accordance with good practice and local regulations. See section “III. g” for information concerning condensate removal for remote models. III. g - INSTALLING THE CONDENSATE EVAP (cont’d): NOTE: Some models, such as single section dualtemperature refrigerator/freezers, are supplied with a bottom-mounted condensate evaporator.
IV. OPERATION IV. a - REFRIGERATORS: Both refrigerators and freezers do not require manual defrosting. During normal operation, a refrigerator continuosly circulates above freezing cabinet air through the coil. A compressor “OFF” cycle occurs every hour to melt any frost which may accumulate on the coil during the compressor “ON” cycle. The control will read “dEF” when this occurs and the evaporator fans will continue to operate.
V. CARE & MAINTENANCE (cont’d) V. a - CLEANING THE CONDENSER: Once the screws are removed, the panel can be pivoted upwards allowing full access to the front facing condenser (see figure 9). V. c - REPLACING THE GASKETS: After the corners are properly inserted, work your way towards the center from both ends by gently hitting with a mallet until the gasket is completely seated in place (see figure 11 for proper gasket placement).
V. CARE & MAINTENANCE (cont’d) VI. OTHER V. g - REPLACING THE LIGHT BULB: All Traulsen R & A Series models are supplied with incandecent lighting unless optional fluorescent lighting was ordered (except for sliding glass door models for which fluorescent lights are supplied standard). VI.
VII. The INTELA-TRAUL® Control System Your new Traulsen Refrigerator, Freezer or Hot Food cabinet is equipped with a state-of-theart electronic microprocessor INTELA-TRAUL® control, which precisely regulates operation and provides alarms when problems occur. It is supplied from the factory completely ready for use and requires no adjustment (except Hot Food units which are set in the “OFF” position, see page for 19 for more info), but without the audible alarms activated.
VII. INTELA-TRAUL® (continued) VII. a - ALARM EXPLANATIONS: *NOTE: Explanation of alarms assume the audible alarm style is set at a 3-second burst or a continuous audible alarm. References to the audible alarm do not apply if the audible alarm style is set to OFF (Refer to page 18 for setting the audible alarm style). High Cabinet Air Temperature: The audible alarm* will sound and the display will read cHI when the temperature inside the cabinet rises above a pre-programmed limit.
VII. INTELA-TRAUL® (continued) VII. c - CONTROL PANEL: LED FOR ° F INTELA-TRAUL 3-DIGIT (RED) LED DISPLAY °F SET ) )) ALARM CANCEL BUTTON DEFROST ICON W / LED DOOR OPEN ICON W / LED FREEZER VII. d - NOTES TO THE USER: You only have 20-30 seconds between button pushes. If you take longer than 30 seconds, the controller will revert back to displaying the cabinet temperature. If you enter the wrong security code, the controller will revert back to displaying the cabinet temperature.
VII. INTELA-TRAUL® (continued) VII. f - CUSTOMER SERVICE PARAMETERS: Listed below are the available parameters in the order they appear, using the down arrow key on the controller. You can use either the up or down arrow keys to scroll through the options.
VII. INTELA-TRAUL® (continued) VII. h - ADJUSTING THE THERMOSTAT SET POINT Differential: This parameter sets the set point differential of the desired cabinet temperature range. Typically, freezers and refrigerators will range from 2° F to 5° F for this parameter setting. This parameter is preset at the factory and does not have to be adjusted unless the customer chooses to do so. Set point differential determines the cabinet temperature at which the compressor come on.
VII. INTELA-TRAUL® (continued) VII. j - SETTING THE 24-HOUR CLOCK: The internal timeclock must be set in order for the data storage memory to correctly log events and to allow any defrost lockout to occur at the correct time of day. If the clock is not set, the control assumes the time is 12 a.m. at the time power is supplied to the unit. The hours on a 24-hour time clock read the following way: H01 = 1:00 a.m. H02 = 2:00 a.m. H03 = 3:00 a.m. H04 = 4:00 a.m. H05 = 5:00 a.m. H06 = 6:00 a.m. H07 = 7:00 a.m.
VII. INTELA-TRAUL® (continued) VII. k - SETTING THE DATE: The date must be set in order for the data storage memory to correctly log events. Follow the instructions to enter the customer access code on page 10. When the control displays Set Point, press the down arrow key until the control display reads button SET . The display will show the arrow keys SET SET . SET keys to set the year. When the correct year is displayed, press the set button (month). The right two numbers will be flashing.
VII. INTELA-TRAUL® (continued) VII. m - STARTING A MANUAL DEFROST CYCLE: This parameter allows a service technician to start a defrost cycle at any time. This parameter will override any lockout settings. Follow the instructions to enter the customer access code on page 10. When the control displays Thermostat Set Point, press the down arrow key display reads until the control Start Manual Defrost. Press the set button SET . The display will show (OFF). Press either arrow key (ON).
VII. INTELA-TRAUL® (continued) VII. n - SETTING THE DEFROST LOCKOUTS: The defrost lockout parameters allow the customer to prevent the unit from going into a defrost cycle for two hours during a set timeframe. Customers can set up to four defrost lockout parameters. They are all programmed the same way. The parameters will be set for the time the lockout is to start. The controller automatically calculates 2 hours from that setting.
VII. INTELA-TRAUL® (continued) VII. o - ADJUSTING THE ROOM TEMPERATURE OFFSET: The room temperature offset parameter allows a service technician or end user the ability to have the display show a temperature that is within three degrees of the actual temperature being read by the cabinet air sensor. This allows for continuity of reading between different temperature reading devices. (i.e.: thermistor Vs thermocouple Vs hand held thermometer) This parameter is preset at the factory to “0” or no offset.
VII. INTELA-TRAUL® (continued) VII. q - VIEWING SENSOR TEMPERATURES: These parameters allow a service technician or customer to view the temperature of all sensors within the unit. The temperatures cannot be adjusted. Follow the instructions to enter the customer access code on page 10. When the control displays Thermostat Set Point , press the DOWN arrow key Cabinet Air Sensor, Evaporator Coil Sensor, unit the display reads and Disharge Line Sensor press the SET button SET .
VII. INTELA-TRAUL® (continued) VII. t - HOT FOOD UNITS, TURNING THE UNIT OFF/ON: After the temperature has been set, the customer can continuously turn the unit OFF and then back ON to the same temperature. To turn the unit ON /OFF press the alarm cancel button , (please note that this feature is not available on versions of the control manufactured prior to September 2000), or if an alarm warning condition is present, use the alternative ON/OFF activation method.
VIII. TROUBLE SHOOTING GUIDE FIND YOUR PROBLEM HERE REMEDY 1. Condensing unit fails to start. a. b. Check if cord & plug has been disconnected. Check INTELA-TRAUL® temperature setting. 2. Condensing unit operates for prolonged periods or continuously. a. b. c. Are doors closing properly? Dirty condenser or filter. Clean properly. Evaporator coil iced. Needs to defrost. See instructions for setting a manual defrost cycle on page 15. Shortage of refrigerant, call service. d. 3.
