1. Safety Precautions
The manufacturer and distributor takes no responsibility for any damage which results from incorrect use of
the unit or not following these instructions.
To guarantee your security and the longest life and working efficiency of the unit, please follow these guides:
1. The unit cannot be installed:
•Outdoors
•In damp places or places which can be easily flooded
•Near flammable or volatile substances
•Near acids or in corrosive environments
2. You must not:
•Store flammable or volatile substances inside the unit
•Touch live parts or connections of the unit
•Operate the unit with wet hands
•Put water vessels on the unit
•Climb on or put any heavy objects on the unit
•Touch the compressor and condenser whilst the unit is connected to the mains
•Overload the shelves
3. You should:
•Always check that the door remains closed
•Use only mains power with an earth to avoid electric shocks
•Handle the power cable using the protective cover and not the cable itself
•Disconnect the unit from the mains before undertaking any repairs or maintenance work
•Protect the power cable and the plug from damage
•Disconnect the power plug before moving the unit
•Disconnect the power plug if you are not going to use the unit for a long period of time
•Disconnect the power plug and prevent it from being reconnected if it has any visual faults

2. Installation Instructions
When you first unpack the unit, check the overall condition and any accessories that are present. Any
damage during transport or incomplete accessories should be reported immediately.
Whilst carrying or moving the unit, do not tilt it to one side more than 45° from the upright position as there
is the possibility of damaging the compressor. If it is necessary to tilt the fridge when moving, such as to fit
under a door frame, please wait 12 hours before powering the unit on to ensure all oils have drained into
their correct place.
The installation location should meet the following conditions:
•Ambient temperature between 10°C and 28°C
•Low relative humidity of the ambient air below 60%
•Do not use in highly dusty environments
•The unit should be placed on a stable, level surface
•The unit should be placed at least 100mm away from the wall
•The height of the room should be at least 300mm greater than the height of the unit
•If the unit is an under-bench model, the bench should be at least 100mm from the unit and the
bench should be vented for airflow
•The unit should not be exposed to direct sunlight
•The unit should be kept away from heat sources
•The unit is not designed to be built in without adequate ventilation
•The unit should be plugged into a surge protector to protect against over-voltage and damaging
power spikes
If you don’t comply with the above recommendations, the unit will not run optimally and you may affect the
overall life of the unit. You may also lose your warranty.
If it is not possible to locate the unit in a place that fully complies with the above conditions, make sure that
at least the following points are followed:
•If the room temperature is higher than recommended, monitor the temperature in the room using
an additional temperature sensor. If the room temperature exceeds 45°C, a thermal protection
switch will activate to protect the compressor against mechanical or thermal damage.
•If the room temperature is lower than the recommended limit, under no circumstances should you
turn the refrigerator on as this may damage the compressor.
•In highly humid or tropical environments, manual defrosting of the evaporator and chamber walls
often is recommended.
Note: After positioning, secure it by locking the castor wheels (if they are provided on your model) or
extending the adjustment screw feet located underneath the front of the unit.

2.1 Placement of the Contents
To provide optimal air circulation and stable conditions for the contents, please follow the following
recommendations:
•The max height of the contents should not exceed 1/3 of the space below the shelves.
•The contents should be placed in such a way that the horizontal surface between the containers
does not exceed 1/3 of the width and height of an empty shelf.
•The space between the contents, and the contents and the wall, should be more or less equal.
2.2 Internal Moisture Accumulation
In normal operation, water may accumulate on the bottom of the chamber. This is usually a result of
condensation of the water vapour in the air if the set temperature is considerably lower than the ambient air
temperature.
The amount of water depends on the following factors:
•Differences between ambient and set temperatures
•Number and frequency of door openings
•Surface Temperature of contents
•High Ambient Humidity
Note: If water gathers, use a dry cloth to wipe the bottom of the chamber.
Do not use any cardboard boxes, sponges and other hygroscopic materials for storing the contents since
they may increase the relative humidity in the chamber.
2.3 Environmental Protection and Disposal
The packaging protects the unit from any damage during transportation. Most of the packaging can be
recycled. Please handle it according to local environmental protection regulations and dispose of it
appropriately. The unit itself can also be recycled at end of life to save resources.
Please help us to protect the environment.
