4. INSTALLATION INSTRUCTION
This section explains how to install your appliance for the most energy-efficient, safe and quiet operation.
If possible avoid placing the appliance near cookers,
radiators or in direct sunlight as this will cause the
compressor to run for long periods. If installed next to a
source of heat or refrigerator, maintain the following
minimum side clearances:
From Cookers
From Radiators
From Fridges
4" (100 mm)
12" (300 mm)
4" (100 mm)
•Make sure that sufficient room is
provided around the appliance to ensure
free air circulation. Ideally, A space of no
less than 100mm must be left around the
freezer, and ensure you allow gaps as
shown in the below diagram.
The appliance should be located on a smooth surface.
It is forbidden to use the refrigerator outdoors.
Protection from moisture. Do not locate the freezer in moist space to avoid the metal parts rusty. And
do not spray water to the freezer, otherwise it will weaken the insulation and causes current leakage.
Refer to "Cleaning and Care" section to prepare your appliance for use.
If the freezer is installed in unheated areas, garages etc. condensation may form on the outer
surfaces in cold weather. This is quite normal and is not a fault. Remove the condensation by wiping
with a dry cloth.

5. OPERATING INSTRUCTION
Electrical Supply Connection
・Deep Freezer should be connected with AC220 ~ 240 V 50Hz single phase.
・Use of extension cord is not recommended.
・A separate circuit should be drawn from the mains to minimize the voltage drop.
WARNING:
・Keep ventilation openings in the appliance enclosure, clear of obstruction.
・Do not use mechanical devices or other means to accelerate the defrosting process, other than those
recommended by the manufacturer.
・Do not damage the refrigerant circuit.
・Do not use electrical appliances inside the food storage compartment of the appliances, unless they
are of the type recommended by the manufacturer.

6. CARE AND MAINTENANCE
Before you start to use the freezer, please check that:
The interior is dry and air can circulate freely at the rear.
Clean the interior as recommended under "CLEANING AND CARE"
Insert the plug into the wall socket and switch on the electricity supply, then the Red light is On.
Avoid accidental disconnection by taping over the switch. Green light will glow and the compressor
will start running (see Freezer Operation page 6).
You will hear a noise as the compressor starts up. The liquid and gases sealed within the
refrigeration system may also give rise to noise, whether the compressor is running or not which is
quite normal.
If you going to store already frozen food open the freezer lid and check that the freezer has reached
the correct temperature. Then you can put in your already frozen food.
Do not load the appliance immediately after it is Switched ON. Wait until the correct storage
temperature has been reached. We recommend that you check the temperature with an accurate
thermometer
Important Notes:
•If there is a power failure do not open the lid. Frozen food should not
be affected if the failure lasts for less than 20 hours. If the failure is
longer, then the food should be checked and eaten immediately or
cooked and then refrozen.
•If you find that the lid of the deep freezer is difficult to open just after
you have closed it, don’t worry. This is due to the pressure difference
which will equalize and allow the lid to be opened normally after a
few minutes.

6.1 CARE AND MAINTENANCE
Cleaning and Care
We recommend that you Switch OFF the freezer at the socket outlet and pull out the
mains plug before cleaning.
Never use any sharp abrasive instrument, soap, household cleaner, detergent and wax
polish for cleaning.
Use lukewarm water to clean the cabinet of the freezer with a cloth and wipe it dry.
Caution: Do not pour water directly on your appliance near the compressor area
Use a damp cloth wrung out in a solution of one teaspoon of bicarbonate of soda to one
pint of water to clean the interior and wipe it dry.
Excess deposit of ice should be removed on a regular basis using a plastic ice scraper
available from your local store. Large accumulation of ice will impair the performance of
the freezer.
If the freezer is not going to be used for a long period of time switch it OFF, remove all
food, clean it and leave the lid ajar.
Check lid seals regularly to ensure they are clean and free from food particles.
Important Notes:
7
Never use water wash the compressor position, wipe it with a dry cloth thoroughly after
cleaning to prevent rust.

7.Temperature Control
Note : Picture is for illustration only, can vary from actual product
6.1 Temperature adjustment
The temperature of the freezer is adjusted by means of the knob assembled on the thermostat. “1,2,3,4,5” do not
represent a specific temperature. The smaller the No. the higher the temperature, whereas. So, position “5” is being the
lowest temperature.
Figures mean:
“ OFF”
1—5
：Forced Shutdown Point
：Frozen Interval （from -12 ℃to -26 ℃）
The achieved temperatures can vary according to the conditions of use of the appliance, such as: place of the appliance,
ambient temperature, and frequency of lid opening, extent of filling with food of the freezer. The position of the thermostat
knob will change according to these factors. Normally, for an
ambient temperature of approx. 25℃, the thermostat should be adjusted to the mild position.
We recommended that you check the temperature with a thermometer to ensure that the Freezer is kept to the desired
temperature. Remember you must take your reading very quickly since the thermometer temperature will rise very rapidly
after you remove it from the freezer.
Please remember each time the lid is opened cold air escapes and the internal temperature rises. Therefore never leave
the lid open and ensure it is closed: immediately after Food is put in or removed.
Indicator lights
The indicator light set is placed on the front side of the freezer for easy visibility.
Indicator lights mean the following:
Red LED – shows that the appliance is supplied with electric energy.
8
Green LED – shows that the compressor is working.

7.1Storing Frozen Food
Prepackaged commercially frozen food should be stored in accordance with the frozen food manufacturer’s
instructions for a freezer compartment.
To ensure that the high quality achieved by the frozen food manufacturer and the food retailer is maintained
the following should be remembered:
1 ．Put packets in the freezer as quickly as possible after purchase.
2 ．Do not exceed “Use By”, “Best Before” dates on the packaging.
Freezing Fresh Food
Place fresh food to be frozen near the side walls to ensure fast freezing and away from already frozen food,
if possible.
Freezing capacity of your appliance in a 24 hours period is as below:
Never exceed this maximum capacity. Do not freeze too large a quantity at any one time.
The quality of the food is best preserved when it is frozen right through to the center as quickly as possible.
Take special care not to mix already frozen food and fresh food.
