performance of your refrigerator can be expected.
2. NEVER USE A BATTERY CHARGER, A.C./D.C. CONVERTER, OR RECTIFIER
ETC. IN LIEU OF A BATTERY.
These electrical supplies generate high ripples or surge voltages which result is
inverter trouble.
3. NEVER USE A COMMERCIAL INVERTER OR CONVERTER for operating your
refrigerator on A.C. since these devices do not hold the required constant frequency.

system. Your refrigerator has an over current protection
system. Your refrigerator has an over current protection
system incorporated in the electronic circuit to prevent
damage to the inverter which may occur due to the reverse
