Changes Face-liftin models to Greenline models:
Automatic defrost -cycle and design
Changes Greenline models to Previous models: cooling unit, the heating
cartridge, lighting, insulation and electronic controls (Fuzzy Logic).
Electronics
Fuzzy Lo ic
All Greenline models and Facelifting models maintain a con-
stant temperature level which has been set at the beginning
of operation. This temperature level is controlled by
electronic intelligence in an energy-saving way.
Unlike conventional appliances, the electronic control
component does not switch on and off but controls (clocks)
the cooling units heating power in a way which does not
require system circulation to be interrupted.
The electronic controls sensor (A) is an air sensor. This means that the
sensor can react directly to the temperature inside the cooling appliance.
Fuzzy Lo ic with 2 sensors
By means of the second sensor the electronics carries out a leak detection
test. If leaks or blockages in the cooling unit are recognised the miniBar is
shut off by the electronics. The test is done after every defrost cycle
(every 24 hours).
After a Power-On- eset, the controllers software runs a self test routine to
check the function of the sensors. The result of the test is shown with the
length of the first duty-cycle of the heating element (jumper X4).
There are four different states which are shown in the following table:

Status Duty-Cycle
both sensors o.k. 7 sec. ON
air-sensor missing/defective 9 sec. ON
evaporator-sensor missing/defective 12 sec. ON
both sensors missing/defective 15 sec. ON
If the air-sensor fails during normal operation, the software shuts down the
cooling unit in steps to 0.
In refrigerators without evaporator-sensor or if the evaporator-sensor is
defective the leakage test is not carried out.Then the new electronics works
like the previous one without leakage detection.
Automatic Defrost Function
The electronic also regulates the automatic defrosting of the refrigerator.
When the plug has been stuck to the socket the running time of the
refrigerator up to the first defrostin is 15 hours for reenline models
and 39 hours for the new face lift models (RH4XX). For all models the
defrostin takes 2 hours.Then the refri erator works 22 hours and
afterwards defrosts 2 hours. Therfore the starting of the refrigerators
determines the time of defrosting.
For example: Starting at 7.00h = first defrosting 22.00h - 24.00h (for facelift
models 22.00h next day)

Coolin Unit
The cooling unit has been optimised for the Greenline models and Face-
Lifting models. Unlike the cooling units of its predecessors, the Greenline
models and Face Lifting models cooling units can be replaced.
When replacin the coolin unit, however, the heatin element
(heatin shell) must be replaced as well.
Ammonia is used as a coolant. This is a natural compound also used in house
hold cleaning agents (1 litre of Salmiak cleaner contains up to 200g of
ammonia - about twice as much as is used in the refrigerator). For the safety of
hotel guests and personnel, it has been established by inspectors that the
coolant poses no threat to health.
Heatin Shell
The conventional heating element (previous models) is replaced by a hea-
ting shell. The heating shell is situated directly to the cooker tube. An optimal
efficiency ratio is achieved by means of a direct and enlarged contact area.

Li htin (except for RH 356LD/E, RH 456LD/E)
All Greenline and face lifting cooling appliances are equipped with sensor-
controlled lighting. The lightings sensor (proximity switch, A) is activated by
means of a magnet (B) which has been foam-installed into the door.
The lighting mechanism consists of two lamps for 180-250V operation
switched in series. For voltages of 100-140V, the lamps are switched in
parallel by means of a bridge.

Automatic Door Control (electrical)
(for RH356 / RH456 LD E)
When the miniBar is opened, a magnetically operated approximation switch
located underneath on the fridge is activated (FIG 1.)
Depending on the connection (opening/closing mechanism), an electric
circuit is closed or opened. Accordingly, this is registered and processed at
the hotel reception. Note: Electrical rating!
The miniBar´s wiring connection is situa-
ted at the rear of the appliance and con-
sists of a 3-pin terminal strip (1).

appliance. Changes, e.g. bigger door
étagères lead to static changes .
The door could be overloaded.
Any damage due to improper use is not covered by the warranty. The
warranty does not cover any modifications to the appliance or the use of
non-original Dometic parts; the warranty does not apply if the installation
and operating instructions are not adhered to and no liability shall be

Troubleshootin
Ener y Savin Tips
At an average room temperature of approx. 22°C, it is sufficient to
operate the miniBar with an average thermostat setting.
If possible, always store pre-cooled goods.
Do not expose the miniBar to direct sunlight and do not place it close
to a source of heat.
An unobstructed air circulation in the fridge aggregate must be
ensured (ref. chapter 7.0 Installation).
When removing goods, only open the miniBar briefly.
Switch on the miniBar approx. 12 hours prior to stocking.
