Chapter 1 General Information
1-1. General Guidelines
4 |
When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.
1)Leakage Current Cold Check
2)Leakage Current Hot Check
3)Prevention of Electro Static Discharge (ESD) to Electrostatic Sensitive
1-2. Insurance test
1.Check if there is any leak of current.
2.Cut out the power supply before the repair to avoid an electrical shock hazard.
3.In the case of a live-line test, insulating gloves should be worn to avoid potential electrical shock.
4.Confirm the rated current, voltage and capacity before testing with any kinds of instruments.
5.Watch if the upper door is open when you check something at a lower position.
6.Take out every part in the cabinet before moving the machine, especially things like panels (e.g. glass shelf).
7.Please wear intact cotton gloves when repair any parts of the evaporator, so that scratches by the sharp fins can be avoided.
8.If there is a breakdown with the refrigeration system, please surrender the machine to the service center, else the leaked refrigerant may pollute the atmosphere.
9.The refrigerator use AC of 115V with a frequency of 60Hz.
10.A big fluctuation of voltage (exceed the range 115 127V) may cause a start failure of the refrigerator, a burn-out of the control panel and compressor, or an abnormal sound from the compressor in operation. In this condition an automatic voltage regulator over 60W should be added.
11.Take care not to damage the supply line. Don’t yank at the line; pull the plug out gently from the receptacle. Don’t press the line under the cabinet or step on it. Take care not to roll on or damage the supply line when moves the machine from the wall.
12.In the case of leakage of inflammable gases like carbon monoxide, open the door and windows. Don’t pull out or insert the plugs of the appliance.
13.Don’t touch the refrigeration surface of the freezing compartment when the refrigerator is in operation, especially when your hand is wet, else you may be glued to the surface.
14.Pull out the plug of power supply during clearance or power outage. Wait at least five minutes to resume the power supply in order to prevent damage to the compressor caused by continuous restart.
