3. Cleaning
Clean the refrigerator thoroughly at intervals, as
necessary. Remove the shelves; these, the
ca inet interior and the door should e washed with a
warm solution of sodium i-car onate. Finally wipe
over with a cloth rinsed in warm water only, and dry
with a clean cloth. Do not wash any plastic parts in
water that is more than hand warm, and do not expose
them to dry heat. The outside of the ca inet should e
wiped down regularly with a clean, damp cloth.
NEVER USE STRONG CHEMICALS OR ABRASIVE
CLEANING MATERIALS ON ANY PART OF THE
CABINET.
4. Positioning the appliance
When first using this refrigerator please consider the
following points:
ENSURE REFRIGERATOR IS LEVEL
THE PIPEWORK AT THE BACK GETS HOT IN USE
THE REFRIGERATOR HAS NO 'MOTOR' AND IS
THEREFORE VIRTUALLY SILENT
ALLOW AT LEAST 3 HRS. FOR SIGNS OF
COOLING
During the refrigeration process, the appliance
gives off heat from the condenser (under the
upper part of the rear cover) into the surrounding air.
The more ventilated the condenser is, the more
effective the refrigeration will e.
The other condition for satisfactory operation is that
the appliance stands on a flat surface. This is est
seen y placing a glass of water on top of the
appliance.
It is important that the appliance is not directly
exposed to radiated heat (sunlight, radiator, near an
oven, etc.).
4.1. Installation instructions
The refrigerator is equipped with an electrically heated
a sorption cooling unit which is virtually silent in
operation. The fridge is designed for free-standing
installation, ut can e uilt-in if the following
conditions are complied with to ensure satisfactory
operation and maximum cooling efficiency.
IMPORTANT
Please follow the installation details elow
carefully Guarantee is valid for products installed
as descri ed only.
1. The refrigerator must e level oth directions
2. There should e 20mm clearance to the wall
Figure 2.

6
3. Ventilation must e provided as shown in
alternatives A, B, C or D (fig 2-3)
4. The ventilation duct must at least measure
105mm x the width of the refrigerator
5. Only the entire cooling unit must project into
the duct as shown
6. Air passing through the duct must not e
preheated y any source of heat
7. Ventilation grills, if used, must have openings
of at least 200cm2 each
During installation, please ensure the mains plug
is accessi le at all times.
5. Using the appliance
To start the refrigerator connect the plug to the socket
outlet and switch on the socket. The cooling fins
should show signs of cooling after a out 3 hours.
The refrigerator needs a out 6 hours at normal
am ient temperature to reach 6 °C in the storage
compartment.
5.1. Temperature regulation
The usual setting required is in the region of 4 to 5 on
the thermostat kno (Fig. 4), ut this can vary with
conditions of load and installation. If it is found
necessary to alter the setting,the kno can e turned
to a higher num er to produce a colder temperature,
or a lower num er to produce a warmer temperature.
The effect of any adjustment can e checked y
means of the thermometer after leaving the
refrigerator operating for a further period to settle
down again.

6. Changing the feet
Should you wish to install your Health Care refrigerator,
you will not need the 40-mm feet. After having removed
the 40-mm feet, you can then re-attach the 12-mm
feet, located inside the 40-mm feet, to the front and
rear fixing points. The 40-mm feet and the 4 remaining
screws should e retained for future use.
7. Thermometer (Fig. 5)
Refer to the separate instruction leaflet supplied with
the thermometer. The thermometer can e stood up
using the attached stand or alternatively it can e fixed
to the refrigerator door, in which case the sensor wire
should e arranged so that it is not stretched or
damaged when the door is opened.
The temperature sensor is located inside the
refrigerator elow the ottom shelf.
The display will then show the current, maximum and
minimum temperature
inside the refrigerator.
After the first pull down of the refrigerator (allow four
hours) please make a "reset" on the thermometer
ecause otherwise it will keep as "maximum" the
am ient temperature.
It is important to re-set the thermometer regularly to
ensure that the temperature is maintained etween
2°C and 8°C.
The temperature readings may rise temporarily after
opening the door or placing additional items inside the
ca inet.
If applica le the attery transit strip must e removed
to activate the temperature display.
8. Useful suggestion
Do not overfill the appliance. It is advisa le to leave
some space etween the products in the ca inet to
ensure efficient and even cooling. If the shelves are
packed too tightly there may e unaccepta le
temperature variations.
9. Defrosting, cleaning and
maintenance
Frost will gradually form on the cooling surfaces and it
must not e allowed to ecome too thick since it acts
as an insulator and interferes with the cooling.
To defrost, disconnect the refrigerator from the
electricity supply and leave the ca inet door open.
The frost will melt and the defrost water will run
through the drain tu e from the drip channel into an
evaporating vessel located at the ottom rear of the
refrigerator. (Fig. 6) The defrost water will evaporate
automatically into the circulating air and the vessel will
not need emptying manually.

10. Customer service
Before you call a service engineer, carry out the
following simple tests:
Is there a power failure? Check the fuses.
Is the plug firmly connected to the socket and is the
socket switched on? Check the socket y plugging
in another appliance, e.g. a ta le lamp.
Is the thermostat at the correct setting? (normally 3
or 4).
Has the door not een closed properly causing the
inside temperature to rise too quickly?
Is the refrigerator level?
Has the ventilation ecome o structed?
If after checking all the a ove points, the refrigerator
is still not working satisfactorily, contact your nearest
service engineer. State the pro lem, model, product-
and serial-num er.
(Details of the model, product- and serialnum er are
to e found on the data la el in the top left of the
inside compartment.)
This refrigerator is equipped with overheating
protection. An authorised service technician can
check whether this has een triggered or not.
In the event of a fault developing, contact your
nearest Service Centre-see local telephone directory.
