INSTALLING A REFRIGERATOR

How to Install the Refrigerator. 

1. Your shockproof fridge is best installed on a solid surface.
2. Be sure your fridge is not placed near a gas stove, heater or other heat-generating appliances.
3. Adequate ventilation and a suitable distance from each wall (at least 150mm or more) is necessary for maximum cooling efficiency and minimum electric current consumption for “free-standing use” (see Fig. shown below).
4. Avoid installing your fridge close to the kitchen sink or faucet.
5. If you use the fridge under the counter or in the fixing box, please note the following air ventilation conditions.
   • Make vent opening both under fridge or bottom and above fridge top cover.
   • The vent opening size must be larger than 160㎠ for each opening (the more air circulation over the condenser, the more efficiently fridge will operate).

WORK TIPS 

Failure to provide the necessary venting will result in poor refrigeration, continuous compressor operation, accelerated battery discharge and sometimes shorten the life of fridge.

TROUBLESHOOTING

CHECKING POINT ＆ METHOD

【Check 1】 Fuse (Fig.1)

• Check the resistance of fuse by tester.
  

  Test result	Assessment
  0Ω	Normal
  ∞Ω	Broken

  

• 【Check 2】 Input Voltage of the Compressor (Fig.2)
• Checking point
• Check at 2 pin coupler of Inverter (Fig.2) or at input terminals of the compressor. ( Should be checked when the compressor is connected )
  

  Test result	Assessment
  Approx. AC13～18V	Normal
  AC 0 V	Inverter is broken
  Approx. AC13V or lower	Compressor is locked

  

• 【Check 3】 Check the Resistance at the Coil of  Compressor （Fig.3)
• Checking point Remove 2 pin couplers at motor cord, and check.
  

  Test result	Assessment
  Approx. 0.84Ω	Normal
  ∞Ω	Broken
  0Ω	Coil of compressor is short circuit

  

• 【Check 4】 Resistance of Thermistor （Fig.4)
• Checking points Remove the 3 pin couplers from Inverter, and test.
  

  Test result	Assessment
  Approx. 2 kΩ～10 kΩ	Normal
  ∞Ω	Broken
  0Ω	Short Circuit

  

• 【Check 5】 Resistance of Control Assy （Fig.5)
• Checking point Remove 6pin coupler. Check the resistance at between terminals brown and black.
  

  Test result	Assessment
  Dial position OFF ～ 5
  Approx. 17kΩ～5kΩ	Normal
  ∞Ω	Broken
  0Ω	Short Circuit

• 【Check 6】 Check the temperature controller. (Fig.6)
• Checking points Check the voltage at between terminals ORANGE and BLACK.
  

  Test result	Judge
  Approx. DC12-14V	Normal
  DC 0 V	Temperature controller is broken
  12V less than

  Test result	Judge
  Approx. DC12V	Normal
  DC 0 V	Temperature controller is broken
  11V less than

  Test result	Judge
  Approx. DC24V	Normal
  DC 0 V	Temperature controller is broken
  23V less than

• 【Check 7】 Checking the operation of the fan motor. (Fig.7)
• Checking point If want to check the start-up of the fan motor directly, can check by connecting the DC24V directly.

CAUTION

• Please be careful not to mistake the polarity of the power supply.
• When connect with DC24V or wrong polarity, fan motor will fail.
• Please use such as support coupler so as not to short-circuit power.
