CAFF19SI FRIDGE FREEZER
Introduction
The Caple CAFF19SI is an American side by side refrigerator. The
system uses a cold blown air system. The system has only one
evaporator situated in the freezer. A fan distributes the cold air around
the freezer. In the top of the freezer is a damper that opens into the
fridge cabinet. The cold air is blown in to the fridge cabinet by the
freezer fan. When the fridge temperature is reached the damper closes,
stopping the cold air entering the fridge.

2.2 Brief Description of Refrigerating Principle
For the forced air cooling single-system refrigerator, there is only
a finned evaporator mounted generally at the rear of its freezer
compartment. Refrigeration of both its refrigerator compartment and
freezer compartment is achieved by this evaporator and cooled air is
sent to its refrigerator and freezer compartments via air ducts. The
temperature inside its freezer compartment is regulated with the freezer
thermostat, whereas the temperature in its refrigerator compartment
is controlled by regulating the throttle, or alternatively, using a
refrigerator to control the start and stop of compressor, and matching
the evaporator to control the freezer temperature.

Choosing the right location
This appliance should be installed in a room,
which is dry and well ventilated.
In order to ensure adequate ventilation, the
appliance should be at least 1,5cm clear on all
sides from cabinetry, and any units placed above
the appliance must be clear by 1.5cm - allowing
adequate ventilation for the appliance.
see clearance diagram
if located close to a corner adequate spacing
must be left for door opening and removal of
shelves. Refer to diagram
The appliance should be 10cm at least from any
electric or gas cooker and 30cm from any coal
or oil stove. If it is not possible, ensure that
appropriate insulation is used.
Avoid exposing the appliance to direct sunlight,
and sources of heat (radiators, heaters, cookers etc)
if the appliance is situated in a cold environment
(shed, out house, garage etc.) it will affect its
performance. You may find that the performance
of the appliance is not consistent and this may
damage foods. Please ensure that the ambient
temperature does not drop below that specified
by the climate class and that temperature are
maintained as consistently as possible.
Connection to the electricity supply
Connect the appliance to the electrical supply
(220-240V ~ 50Hz) with the plug and lead, which
are fitted. Connections to the mains supply should
be in accordance with local regulations.
NB! This appliance will operate within a range of
187 - 253 V. Operation outside this range may
result in damage to the control panel, thermostat
or compressor, unless a regulator with a capacity
of 750W, or higher is installed.
The appliance must be plugged into an earthed socket.
Always make sure that the plug is accessible
after the appliance has been positioned.

Adjustable feet
Make sure that the appliance is on solid level flooring. If the refrigerator is
placed on a plinth, flat, strong and fire resistant materials must be used.
This appliance has front adjustable feet, which can be used to level the
appliance, or adjust door alignment (see below).
Door Adjustment
The doors may require some alignment adjustment before you connect the
appliance to the electricity supply. This can be done by making minor
adjustments to the feet:
If the freezer door height is lower than the refrigerator door, use a
screwdriver in the slots of the front left hand adjustable foot, turning
clockwise until the freezer door height is raised in line with the
fridge door.
If the freezer door is higher, use a screwdriver in the slots of the
front right hand adjustable foot, turning clockwise until the fridge
door height has changed in line with the freezer door.

DISPLAY PANEL
Once the fridge freezer has reached the preset temperatures the compressor
will switch off. 30 minutes later the display panel will darken, This is an energy
saving measure and is completely normal. This may cause the customer to
contact the customer care service line to report the fridge freezer has, or keeps
switching off. The customer should be assured that this is normal and not a
malfunction.
To light the display panel push any of the buttons on the display or open the
doors.
CONTROL PANEL
The factory preset for the freezer is -18 and for the fridge +3.
The control panel has four control buttons. These are (from left to right)
FAST FREEZE CONTROL BUTTON, FREEZER TEMPERATURE CONTROL,
REFRIGERATOR TEMPERATURE CONTROL BUTTON, ICE/WATER
OPTION BUTTON.
The temperature is displayed as coloured segments. Each segment is a
temperature setting 1-5. The temperatures are as follows:
FREEZER TEMPERATURES FRIDGE TEMPERATURES
1 = -15 1 = +7
2 = -17 2 = +6

The air damper is mounted at the top/back of the fridge compartment. To check
the damper is working - check that there is air flowing from the vents in the front
of the damper. If the fridge compartment is switched off via the control panel
the damper should close and the airflow cease. When the fridge compartment is
switched back on the damper will reopen and air flow resume.
DAMPER REMOVAL
On the bottom of the damper assembly there is a light cover. Remove the light
cover by removing the two screws fixed at the front top edge. When the cover is
pulled down and to the right the assembly will drop down. Unplug the connectors
and remove the assembly.
FRIDGE SENSOR REMOVAL
The top sensor is mounted in the damper assembly housing. Remove as above.
The bottom sensor is mounted two thirds of the way down the right hand side of
the fridge wall. To remove the sensor unclip the cover and pull the sensor forward.
Cut the wires close to the sensor head. Join the new sensor to the old lead by
soldering and protecting with heat shrink. Refit the sensor and cover.
The fridge compartment has
a damper assembly that
controls the cold air that is
blown into the fridge.
Two sensors top and bottom
control the temperature.
If the temperature rises by
four degrees between the
sensors cold air is blown
into the fridge compartment
