Page 13 321199 Installation instructions: Ensure that the refrigerator is not plugged into a power supply. Locate the isolation tap for the water connection – cold water feed only (dishwasher or sink mixer taps) – if you can’t find the connection tap, contact an authorised plumber in your state or town to fit your water connection.
Page 14 321199 Attach double sided foam to the back of the water filter head as shown in Diagram 5. Write the date to be replaced on the filter (date installed + 6 months). Remove the double sided foam backing and attach the filter to the desired position as located in step 10 (refer to previous page).
Page 15 321199 Important! • All connections must be checked for leaks. • If unsure of connection process and/or leaks, then contact your local plumber to install and check the system for you. • Ensure white 6 mm (¼”) tubing is routed away from sharp objects, sharp corners (beware of kinking tube as this will stop water flow), clear of the refrigerator unit compartment and not in a location where it can be squashed.

Page 17 321199 Removing & Replacing Freezer Drawer • Open the drawer as far as possible, then remove the screw on each side of the drawer. • Pull the drawer body upwards and outwards, and put aside in a safe place. • Replace the freezer drawer in a reverse sequence to removal. Adjusting The Height-Adjustable Shelf The height of the shelf can be adjusted to meet individual storage needs.
Page 18 321199 Replacing the Light Bulb (Provision Compartment) Bulb specifications: 220V~, 25W Socket: E14 (DO NOT use a bulb over 25Watts) To replace the light bulb: • Unplug the appliance. • To remove the light shield, press the stopper at rear out of the square hole.
Page 19 321199 5.10 How to Use the Delicatessen Drawer The appliance is equipped with a delicatessen drawer with a temperature range from -2°C~+3°C. The temperature can be adjusted by the air control knob to meet storage needs. • Turn the air control knob leftwards (weak) to reduce the cooled air moving into the delicatessen drawer and maintain a higher temperature.

Page 27 321199 ELECTRICAL CONTROL PRINCIPLES Overview The evaporator fan in the freezer compartment circulates air around the FC. The air is also moved into the provision compartment, with the flow being controlled by an air damper located between the FC and PC. The temperature in the PC is controlled by the PC sensor controlling the switching of the air damper.
Page 28 321199 Defrost Control When the cabinet has been switched on for the first time, or after a replacement control board has been fitted, the very first defrost will occur after 4 hours. If the PC sensor temperature is greater than 10 C, a defrost will occur.

Page 47 321199 TROUBLESHOOTING 14.1 Troubleshooting And Repair 14.1.1 Normal Phenomena – Not Faults Of The Refrigerators In a domestic refrigerator, there is not only a complicated electric control system, but also a refrigerating system that is difficult to discern whether it is in a good working condition. Both the systems are related and affect each other.
Page 48 321199 14.2 Three Essentials For Faultfinding 14.2.1 Look Check the tubing of the refrigerating system for cracks and various welding points for leaks. If leakage occurs, an oil stain can usually be seen. Check the suction and exhaust pressure values (high pressure and low pressure) of the compressor to see whether they are normal.
Page 49 321199 14.3 Analysis Of Troubles And Troubleshooting 14.3.1 Poor Refrigerating Effect The so-called “poor refrigerating effect“ refers to the fact that the refrigerator can operate and refrigerate normally, but the temperature in the refrigerator cannot drop to the prescribed value under the stipulated working conditions.
Page 50 321199 Low efficiency of compressor Analysis of Trouble Low efficiency of a refrigerating compressor refers to the actual reduction of gas discharge capacity, and hence the corresponding reduction of refrigerating capacity, under the condition in which the refrigerant in the system is unchanged. This phenomenon occurs mostly when the compressor has been used for quite a long time, its moving parts have worn to a considerable degree, the fit clearance between various parts have increased and the sealing property of its gas valve has deteriorated, resulting in a decrease in its actual gas discharge capacity.
Page 51 321199 Symptoms of total leakage of refrigerant are mainly as follows: • The compressor can be started easily (if there is no damage to the compressor parts). • Its operating current becomes low. • Its gas suction pressure is high and discharge pressure is lower. •...
Page 52 321199 Clogging in filter Analysis of Trouble Total clogging of a filter rarely occurs. The paste-like matter formed from the substances filled into the system mostly causes this trouble, or other dust after the refrigerator has been used for a longer time, or by the dirt accumulating gradually inside the filter.
Page 53 321199 Air left in the system Analysis of Trouble The residual air in the system will circulate together with the refrigerant in the system. The major symptoms caused by this residual air are higher gas discharge pressure, higher discharged gas temperature (the gas discharge tubing is considerably hot when you feel it with your hand), and poorer refrigerating effect.
Page 54 321199 Inspect the power supply to see whether it is connected to the compressor circuit. Analysis of Trouble If 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 the correct measures to remove the fault.
Page 55 321199 Poor electric contractor in thermostat Analysis of Trouble Burnout of the contractor and leakage of temperature sensing agent may occur generally. Remedy Replace the old with a new one. Check the terminals for loose connection and electric circuits for other abnormal phenomena. 14.3.5 Mechanical Faults Of Compressor Seizing of shaft...
Page 56 321199 No stoppage of compressor due to damaged cabinet insulation and/or door seal Analysis of Trouble When the cabinet insulation deteriorates or the door seal is not sealing correctly, the temperature in the refrigerator will rise and keep the compressor running continuously. Remedy Check the cabinet insulation for damage.
Page 57 321199 Inspection method To find the sources of noise, press the vibration spot with your hand while the refrigerator is in operation and listen carefully to determine whether the vibration becomes weaker or vanishes. If the refrigerator has not been placed level, put a level on its top table and adjust the levelling feet. If noise occurs from the compressor, strike different locations on the side surface of its case using a rubber hammer or hand hammer with a wood block in-between so as to determine whether the suspended springs are out of balance or are seized.
