Page 6: Safety Precautions
SAFETY PRECAUTIONS This appliance uses an 115V~/60Hz AC for power supply. If the voltage has excessive variations, it is likely that the appliance will not start or a malfunction might occur such as an abnormal working noise of the compressor. In this case it is required to use a voltage regulator of 750W or more. - Page 7 In case of a damaged or worn out power cable; it is not advisable to continue its usage. It is required to have it replaced by a qualified technician from any authorized service shop. Whenever there is a leakage of an inflammable gas, close the valve of the leaking gas.
- Page 8 It is not advisable to put inflammable or explosive articles, strong corrosive acids and alkali substances into the appliance. Do not keep medicine, vaccine or chemical inside the appliance. The refrigerator is strictly meant for household purposes and should not be used to store items that require a specific temperature during storage.
- Page 9 Do not place any electrical plugs, regulators or microwaves on top of the refrigerator. Do not use other appliances - except those allowed/stated by manufacturer – inside the refrigerator. Do not play with the appliance by hanging on its door, to avoid toppling of the appliance and falling to hurt the individual.
- Page 10 When the refrigerator is running, take care not to touch the cold surface of the freezer compartment, especially with wet hands; otherwise your skin is likely to get stuck on the cold surface. Do not spray water onto the refrigerator or place it in a wet area likely to be splashed with water, so as to avoid neutralizing the electric insulation performance of the appliance.
- Page 11 Do not put bottled drinks or beverage into the freezer compartment to prevent cracking when frost occurs. It is required to pull out the power plug or to wait for 5mins before switching on the appliance again during cleaning or when there is no power supply to avoid damaging the compressor by continuous start and stop.

Page 22: Troubleshooting And Repairs
TROUBLESHOOTING AND REPAIRS NORMAL REFRIGERATOR FUNCTIONS A domestic refrigerator is comprised of an electric control system and a refrigerating system. Since both systems work together, it is difficult to tell whether the refrigerating system is in good working condition. If any part of the refrigerating system or electric control does not work properly, the refrigerator’s efficiency will decline, operating properties will destabilize, and in worst cases, it will not function at all. - Page 23 COMMON PROBLEMS OF A REFRIGERATOR AND THEIR SOLUTIONS Refrigerator problems are closely related to the quality of components, level of workmanship, and owner maintenance. The parameters generally used to determine the working conditions of a refrigerator include the temperature inside the refrigerator, the operating rate, electrical power consumption, noise level, and other functional indices.
- Page 24 Listen a) Listen to the noises made while the compressor is running. During the normal operation of compressor, a slight and uniform humming sound due to undulation of electric currents will be heard. The sounds listed below indicate a malfunction. Humming sounds from a fully enclosed aggregate unit indicate that the motor was not started properly.
- Page 25 d) Feel the temperature of exhaust gas from the refrigerating system. The exhaust gas should be extremely hot. If the refrigerator has an enclosed compressor refrigerating system, there should be no frost or condensation on the gas suction tube. However, frost and condensation may appear for a very short time period immediately after starting the machine.
- Page 26 b) If excessive refrigerant has been charged, the liquid refrigerant that cannot evaporate in the evaporator will return to the compressor. This will cause “liquid striking.” The liquid refrigerant evaporates and effervesces as soon as it flows into the refrigerating oil at the bottom of compressor. If the condition is severe, foams will cover the inside the compressor housing and be sucked by the piston, causing damage to the components of compressor.
- Page 27 Remedy Turn the refrigerator off and prepare for defrosting. Open the refrigerator’s door to allow air inside or use a fan to speed up air moving into the refrigerator to quicken the defrosting process. Never strike the frost layer with any iron tool or wooden stick in order not to damage the evaporator tubing.
- Page 28 1) The entire refrigerant has leaked Analysis of Trouble Leak points in the refrigerating system have not been found and repaired timely, allowing refrigerant to leak completely. There are two kinds of leaks: slow leaks and fast leaks. Symptoms of total leakage of refrigerant are: The compressor can be started easily (if there is no damage to the compressor parts) The operating current becomes low...
- Page 29 Remedy If there is too much moisture in the refrigerating system, release the refrigerant, purge the tubing with nitrogen, and then refill the system with the filtered refrigerant. Another method is to connect a filter with moisture absorbers, such as silica gel or anhydrous calcium chloride, to the refrigerating system. Next, replace the filter, evacuate it again, and fill the system with refrigerant.
- Page 30 • Compressor suddenly stops Very often, when the compressor suddenly stops, the gas suction pressure and/or discharge pressure have exceeded their respective prescribed ranges. When this happens, the pressure-operated protective relay automatically shuts off the power to the compressor. Below we discuss the reasons for high gas discharge pressure and low suction pressure.
- Page 31 Stoppage due to electrical troubles Thermostat is out of control due to electric troubles Analysis of Trouble In case the thermostat does not work in its good order or its temperature sensor has not been installed properly, frequent stoppage is also likely to occur. Remedy Try to adjust the temperature sensor’s position until the compressor can be started and stopped normally.
- Page 32 a) Inspect the power supply to see whether it is connected to the compressor circuit. Analysis of Trouble In case the compressor cannot be started, this will generally exhibit in the power supply circuit, for instance, power failure, poor contact of switch, and blown fuse. Make a comprehensive analysis of these phenomena, find out its real cause and take corrective measures to resolve the problem.
- Page 33 d) Problems of motor and other electrical faults i) Motor windings are damaged or there is a short circuited between turns Analysis of Trouble When motor windings are damaged or there is the occurrence of a short circuit between turns, the fuse will be blown repeatedly, and the blowout particularly occurs at that instance where you close the knife switch.
- Page 34 ii) Seizing of piston This happens because the fit clearance between the piston and cylinder is too small or expansion due to heat. iii) How do you know that the shaft and piston have been seized When the refrigerator is switched on, the compressor will not start running. A slight hum sound will be heard and several seconds later, the thermal protective relay will actuate and open the contacts.
- Page 35 c) Evaporation temperature is too high in refrigerating system, resulting in lower refrigerating capacity and hence continuous running of compressor Analysis of Trouble Leakage of refrigerant and clogging in a refrigerating system will directly affect its refrigerating capacity. Due to the reduction in its refrigerating capacity, the refrigerator temperature cannot reach its rated value.
- Page 36 Electric leakage test Slight electric leakage A tingle sensation will be experienced as soon as you touch the metal parts of the refrigerator with the hand. When you test them with a test pencil, its neon lamp will come on. In that case, the first thing you need to do is to determine whether the grounding is perfect.
- Page 37 Remedy: For reason “a”, fasten the fan’s motor. For reason “b” or “c”, replace the fan’s motor or impellers. 5. Inspection method To find the sources of noise, press the vibration spot with your hand while the refrigerator is in operation and listen attentively whether the vibration becomes weaker or vanishes.
