IMPORTANT:
NEVER USE WIRING LESS THAN AWG # 12 BETWEEN THE BATTERY
AND REFRIGERATOR.
INSTALL A 10 AMP FUSE IN THE POWER SUPPLY CIRCUIT
.
BE SURE THE POWER SUPPLY POLARITY IS CORRECT.
In the event that the green refrigerator light fails to glow inspect the power source for
proper voltage and correct polarity. The inner contact point of the DC power source
adapter must be positive and the outer contact negative (ground).
CONNECT REFRIGERATOR DIRECTLY TO THE BATTERY TO REDUCE RADIO
NOISE INTERFERENCE.
Reducing radio noise interference can be accomplished by twisting the power
supply wires together and attaching them directly to the battery, adding an 10 AMP
fuse near the positive battery connection. Avoid splicing other devices into this circuit
as interference may occur.
QUICK CHARGING THE BATTERY.
Never hook the freezer up to a battery charger directly. It must only be attached to a
battery.
OPERATING YOUR REFRIGERATOR USING A PORTABLE GENERATOR UNIT.
The internal refrigerator power supply unit may be damaged if powered by an older
style generator units without automatic voltage regulation. The only acceptable
generators to use are those which are “inverter style” or those with over-voltage
protection. Please contact your ENGEL dealer for additional instruction on safe use
when powering your refrigerator with a portable generator unit.
MAINTENANCE OF YOUR BATTERY IS IMPORTANT
1.
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.
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 could result in damaging your Engel’s power supply.
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. It is safer and more economical to run your refrigerator directly off
DC power.
