INSTRUCTIONS FOR USE
0 Current Sources.
1.1. Connection to 220v-240v,50Hz AC Mains. (Except MODEL SB47F)
Your Engel refrigerator may be connected to a standard domestic mains power source, using
the three-core mains lead provided. Set the thermostat control knob to "0 (OFF) until the
current has been turned on. Then, set the thermostat control knob to 1 -5" aand the green
lamp will light up. Turn the thermostat control knob to the required setting.
1.2. Connection to 12 24V DC Batteries.
Ensure that the battery voltage corresponds with the voltage stated on the refrigerator label.
If the voltage applied is too high it will damage the inverter. If it is too low the cooling
efficiency will be reduced, the running time will increase and thus the battery will be Subjec-
ted to an increased loading.
Set the thermostat control knob to "0" (OFF). Remove the protective shield from trom the
DC input compartment and connect the two-core cable from the battery, being careful to
ensure polarity is correct (i.e. positive to positive, negative to negative). Then return the
protective shield to the original place.
1.3 Automatic battery/mains Switching.(Except MODEL SB47F)
All Engel refrigerators are built with voltage selection based in favour of 220V-240V. AC.
If mains current is applied whilst the refrigerator is operating from s DC battery source, a
relay immediately switches to mains operation. When the mains current supply is terminated
the refrigerator will automatically revert to battery operation.

Installation and Operation.
The refrigerator should be mounted in a convenient dry location, where it is not subjceted to
splashing from water or other liquids or to radiant or conducted heat from hot pipes, warm
air outlets, cookers etc. Also ensure that it is not exposed to direct sunshine. Although care
is taken to ensure that Engel refrigerators leave the factory in a clean condition, users are
recommended to wipe out the interior with a clean damp cloth, followed by drying with a
clean dry cloth, before using a refrigerator for the first time.
The thermostat control knob serves the dual purpose of governing AC and DC operation.
(Except MODEL SB47F )
The thermostat control knob serves the purpose of governing DC operation.(MODEL SB47F

When turned as far as possible in an anticlockwise direction the setting is "1" (REF). When
turned as far as possible in a clockwise direction, the setting is

or (MAX) This Corres-
ponds to a very low temperature , 0"C or less. Depending upon the prevailing ambient
temperature, the refrigerator should initially be allowed to run for from 30 to 45 minutes
at the maximum thermostat setting (fully clockwise), and the control should then in an
anticickwise direction to select the desired refrigeration temperature. For example, the ideal
refrigeration temperature for storing those foodstuffs normally kept in
refrigerators
is in the
range from +4°C to +9°C

Defrosting
Due to the humidity of the air inside the refrigerator storage space, frost will form on the
surface of the evaporator when this has been working for some time. A layer of frost in ex-
cess of about 6mm (+in.) has an adverse effect upon cooling efficiency; therefore the evapo-
rator must be defrosted at regular intervals. For this purpose, set the thermostat control knob
to "0" (OOFF). After defrosting the cabinat interior must be cleaned and dried before the
refrigerator is set the thermostat control knob to" 1-5" again.

Safety Devices.
2.1. Polarity Guard for DC Battery Operation.
In order to protect the inverter from damage caused by incorrect polarity the refrigerator is
fitted with an automatic polarity guard. Should incorrect polarity be applied, the green power
lamp will not light and the refrigerator will not operate. Check the fuse and following correction
of the current supply, the green power lamp will light up and normal operation will be resumed.
However, if the green power lamp does not light, this indicates a possible inverter defect, and
users are advised to contact their Engel dealer for service. (See Fig.1)
