BATTERY MAINTENANCE
MAINTENANCE OF THE BATTERY IS IMPORTANT
If your battery is old (more than 3 years) or not properly charged, a decline in the
cooling performance of your refrigerator can be expected.
NEVER USE A BATTERY CHARGER, AC/DC CONVERTER, OR RECTIFIER ETC. IN
LIEU OF A BATTERY
These electrical supplies generate high ripples, or surge voltages, which could result
in damaging your ENGEL's internal power supply.
NEVER USE A COMMERCIAL INVERTER OR CONVERTER
Never use a commercial inverter or converter for operating your refrigerator on AC.
These devices do not hold the required constant frequency. It is safer and more
energy efficient to run your refrigerator directly with DC power.
OPERATION
To start your refrigerator, set the thermostat control dial to "ON." Your refrigerator
should start operating. The interior should start getting cool to touch within a few
minutes.
PROTECTION SYSTEM
The DC power cord is made for a negative (-) ground system. Your refrigerator has
a high current protection system incorporated into the electronic circuit to prevent
damage to the power supply which may occur due to a reverse connection.
If your refrigerator does not operate and the power lamp on the refrigerator is not
illuminated, you may have:
- Connected the refrigerator with the incorrect polarity
- Blown a fuse in the DC Cord / Plug
- Blown a blade fuse on the refrigerator
- Insufficient voltage from the power source
- A problem in the inverter
