fore the work is completed can cause serious accidents such as electric shock or fi re.
• If refrigerant leaks when you are working, ventilate the area. If the leaking refrigerant
is exposed to a direct fl ame, it may produce a toxic gas.
• Installation must be performed in accordance with regulations, codes, or standards for
electrical wiring and equipment in each country, region, or the installation place.
• Do not use means to accelerate the defrosting process or to clean, other than those
recommended by the manufacturer.
• This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless

material away from young children.
• The appliance shall be stored in a room without continuously operating ignition
sources (for example: open fl ames, an operating gas appliance or an operating
electric heater).
• Do not pierce or burn.
• Be aware that refrigerants may not contain an odour.

• Always use a separate power supply line protected by a circuit breaker operating on
all wires with a distance between contact of 3 mm for this product.
• To protect the persons, earth (ground) the product correctly, and use the power cable
combined with an Earth Leakage Circuit Breaker (ELCB).
• This product is not explosion proof, and therefore should not be installed in an explo-
sive atmosphere.
• To avoid getting an electric shock, never touch the electrical components soon after
the power supply has been turned off. After turning off the power, always wait 5 min-
utes or more before you touch the electrical components.
• This product contains no user-serviceable parts. Always consult experienced service
