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.
