4 SAFETY PRECAUTIONS Read all the instructions before using the appliance. When using this appliance, always exercise basic safety precautions, including the following: 1. Use this appliance only for its intended pur pose as described in this operation manual.
5 1. Always connect CO 2 gas cylinder to a regulator. Failure to do so could result in an explosion with possible death or injury when the cylinder valve is opened. 2. Never connect CO 2 gas cylinder directly to beer keg. 3. Always secure CO 2 gas cylinder in an upright position.
6 REFRIGERATING PRINCIPLE Schematic diagram of refrigerating principle • Brief Description of the Refrigeration Principle The refrigerating system of direct cooling single-system refriger ators belongs to the category of dual temperature and single-cont rol refrigerating system.

8 TROUBLESHOOTING AND REPAIRS 1. NORMAL REFRIGERATOR FUNCTIONS A domestic refrigerator is comprised of an el ectric control system and a refrigerating system. Since both systems work together, it is di fficult to tell whether the refrigerating system is in good working condition.
9 2. COMMON PROBLEMS OF A REFRIGERATOR AND THEIR SOLUTIONS Refrigerator problems are closely relat ed to the quality of components, level of workmanship, and owner maintenance.
10 iii. Whistling sounds indic ate the release of high-pressure gas from a crack in the pressure tube inside the compressor. iv. Clucking sounds indicate that the suspended spring inside the compressor has broken v.
11 a. Poor Refrigerating Effect The “poor refrigerating effect “refers to w hen the refrigerator operates normally, but does not cool to the temperature indicated by t he thermostat.
12 Analysis of Trouble Residual air in the refrigerat ing system will reduce its refrigerat ing efficiency. Major effects are an increase in temperature of the segment from the comp ressor outlet to the condenser inlet and an increase in gas suction and exh aust pressures.
13 temperature of discharged gas, and, for seve re cases, condensation and frosting may appear. Remedy Purge the tubing. After replacing the dry filter or cleaning it t horoughly, refill the system with refrigerant and seal the charging port.
14 - Water accumulates and gradually clogs the narrow part of the capillary, - Frost to melt at t he evaporator, there is no sound of gas flowing, - The gas suction pressure becomes a vacuum.
15 Remedy It is quite difficult to differentiate this trouble from others because they have similar symptoms. When repairing, lis ten attentively for abnorma l sounds coming from the compressor. Oftentimes, broken pieces of valv e block strike against the cylinder.
16 in the system, you have to open the tubing, re-evacuate it and then charge it with refrigerant. Stoppage due to electrical troubles Thermostat is out of cont rol due to electric troubles An.
17 In case the compressor cannot be started, you must find out the origins of this trouble through systematic checkup, because probably there are many causes, including the electrical and mechanical parts. a) Inspect the power supply to see whether it is connected to the compressor circuit.
18 temperature sensor. Try to turn the adjusting stem of this value in the direction of the lower temperature graduation, and then check the contacts to s ee whether they are closed. If they are still not closed, dismantle the temper ature-sensing disc and then immerse it into warm water to see whether the contacts actuat e.
19 This is normally caused by poor lubrication, insufficient quantity of lubricant, clogging in the lubricant oil’s line, or intermittent lubrican t oil supply. Dirt and ot her impurities in the lubricant will increase its visco sity and cause the shaft to be seized.
20 Analysis of Trouble Leakage of refrigerant and cloggin g in a refrigerating system will directly affect its refrigerating capacity. Due to the reduction in its refrigerati ng capacity, the refrigerator temperature cannot reach its rated value. The thermostat will not work, thus the compressor runs continuously.
21 A tingle sense 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 y ou need to do is to determine whether the grounding is perfect.
