Page 5: Proper Disposal
True Food Service Equipment, Inc. PROPER DISPOSAL OF THE REFRIGERATOR Child entrapment and suffocation are not problems of the past. Junked or abandoned refrigerators are still dangerous… even if they will sit for “just a few days.” If you are getting rid of your old refrigerator, please follow the instructions below to help prevent accidents. Before You Throw Away Your Old Refrigerator or Freezer: • Take off the doors. • Leave the shelves in place so that children may not easily climb inside. USE OF EXTENSION CORDS NEVER USE AN EXTENSION CORD! TRUE will not warranty any refrigerator that has been connected to an extension cord. -
Page 6: How To Connect Electricity
HOW TO CONNECT ELECTRICITY Do not, under any circumstances, cut or remove the ground prong from the power cord. For personal safety, this appliance must be properly grounded. The power cord of this appliance is equipped with a grounding plug which mates with a standard grounding wall outlet to minimize the possibility of electric shock hazard from this appliance. Have the wall outlet and circuit checked by a qualified electrician to make sure the outlet is properly grounded. If the outlet is a standard 2-prong outlet, it is your personal responsibility and obligation to have it replaced with the properly grounded wall outlet. The freezer should always be plugged into it’s own individual electrical circuit, which has a voltage rating that matches the rating plate. This provides the best performance and also prevents overloading building wiring circuits which could cause a fire hazard from overheated wires. -

Page 11: Electrical Instructions
True Food Service Equipment, Inc. INSTALLATION / OPERATION INSTRUCTIONS ELECTRICAL INSTRUCTIONS A. Before your new unit is connected to a power supply, check the incoming voltage with a voltmeter. If anything less than 100% of the rated voltage for operation is noted, correct immediately. B. All units are equipped with a service cord, and must be powered at proper operating voltage at all times. Refer to cabinet data plate for this voltage. TRUE requires that a sole use circuit be dedicated for the unit. Failure to do so voids warranty. SEALING CABINET TO FLOOR Step 1 - Position Cabinet Allow three inches between the wall and rear of the GDM freezer for proper ventilation. - Page 12 INSTALLATION / OPERATION INSTRUCTIONS STARTUP A. The compressor is ready to operate. Plug in the cooler. B. Temperature control set at No. 4 position gives freezers an approximate temperature of 20°F - 25°F. Allow unit to function several hours, completely cooling cabinet before changing the control setting. C. Excessive tampering with the control could lead to service difficulties. Should it ever become necessary to replace temperature control, be sure it is ordered from your TRUE dealer or recommended service agent. D. Good air flow in your TRUE unit is critical. Be careful to load product so that it neither presses against the back wall, nor comes within four inches of the evaporator housing. Refrigerated air off the coil must circulate down the back wall..www.truemfg.com ... True Food Service Equipment, Inc. NOTE If the unit is disconnected or shut off, wait five minutes before starting again.

INSTALLATION / OPERATION INSTRUCTIONS FREEZERS DEFROST TIME CLOCK OPERATION (Grasslin Timer) RECOMMENDED DEFROST SETTINGS: TRUE Manufacturing has factory set your defrost time clock to a recommended time and duration defrost scenario. All refrigeration equipment operating below 30°F will accumulate frost on the evaporator coil and will require routine defrost. Your TRUE equipment has been designed for three defrost periods (6:00 a.m., 2:00 p.m. and 10:00 p.m.). If you decide to deviate from these defrost time settings please follow the procedures for adjustment below. REQUIRED TOOLS: • Phillips Screwdriver • 1/4” Nut Driver or Socket Locating The Defrost Timer: Take off louvered grill assembly by removing four (4) corner screws.

Page 14: Maintenance, Care & Cleaning
IF THE COMPRESSOR WILL NOT RUN 1. If there is no voltage at the compressor terminals, follow the wiring diagram and check back from compressor to the power supply to find where the circuit is interrupted. 2. If power is available at the compressor terminals, and the compressor does not run, check the voltage at the compressor terminals while attempting to start the compressor. If voltage at the compressor terminals is below 90% of the nameplate voltage, it is possible the motor may not develop sufficient torque to start. Check to determine if wire sizes are adequate, electrical connections are loose, the circuit is overloaded, or if the power supply is inadequate. 3. On single phase compressors, a defective capacitor or relay may prevent the compressor starting. If the compressor attempts to start but is unable to do so, or if there is a humming sound, check the relay to see if the relay contacts are damaged or fused. The relay points should be closed during the initial starting cycle, but should open as the compressor comes up to speed. Remove the wires from the starting relay and capacitors. Use a high voltage ohmmeter to check for continuity throughout the relay coil. Replace the relay if there is not continuity. Use an ohmmeter to check across the relay contacts. Potential relay contacts are normally closed when the relay is not energized, current relay contacts... -

True Food Service Equipment, Inc. 4. If all operating conditions are normal, the voltage supply at the compressor terminals balanced and within limits, the compressor crankcase temperature within normal limits, and the amperage drawn within the specified range, the motor protector may be defective, and should be replaced. If the operating conditions are normal and the compressor is running excessively hot for no observable reason, or if the amperage drawn is above the normal range and sufficient to repeatedly trip the protector, the compressor has internal damage and should be replaced. IF THE COMPRESSOR RUNS BUT WILL NOT REFRIGERATE 1. Check the refrigerant charge. Check the evaporator surface to determine if it is evenly cold throughout, or if partially starved. A lack of charge may be indicated by light, fluffy frost at the evaporator inlet. Add refrigerant if necessary. 2. Check the compressor suction pressure. An abnormally low pressure may indicate a loss of refrigerant charge, a malfunctioning capillary tube, a lack of evaporator capacity possibly due to icing or low air flow, or a restriction in the system. - Page 16 MAINTENANCE, CARE & CLEANING CLEANING THE CONDENSER COIL When using electrical appliances, basic safety precautions should be followed, including the following: REQUIRED TOOLS: • Phillips Screwdriver • Stiff Bristle Brush • Adjustable Wrench Step 1 Disconnect power to unit.

Page 17: Important Warranty Information
True Food Service Equipment, Inc. MAINTENANCE, CARE & CLEANING IMPORTANT WARRANTY INFORMATION Condensers accumulate dirt and require cleaning every 30 days. Dirty condensers result in compressor failure, product loss, and lost sales... which are not covered by warranty. If you keep the Condenser clean you will minimize your service expense and lower your electrical costs. The Condenser requires scheduled cleaning every thirty days or as needed. - Page 18 Stainless Steel Equipment Care and Cleaning CAUTION: Do not use any steel wool, abrasive or chlorine based products to clean stainless steel surfaces. • Stainless Steel Opponents There are three basic things which can break down your stainless steel’s passivity layer and allow corrosion to rear its ugly head. 1) Scratches from wire brushes, scrapers, and steel pads are just a few examples of items that can be abrasive to stainless steel’s surface. 2) Deposits left on your stainless steel can leave spots. You may have hard or soft water depending on what part of the country you live in. Hard water can leave spots. Hard water that is heated can leave deposits if left to sit too long. These deposits can cause the passive layer to break down and rust your stainless steel. All deposits left from food prep or service should be removed as soon as possible. 3) Chlorides are present in table salt, food, and water. Household and industrial cleaners are the worst type of chlorides to use. 8 steps that can help prevent rust on stainless steel: 1. Using the correct cleaning tools Use non-abrasive tools when cleaning your stainless steel products. The stainless steel’s passive layer will not be harmed by soft cloths and plastic scouring pads. Step 2 tells you how to find the polishing marks.
