Haier DW-40W100J, Operation Manual

18

Any of the following event will be normal, please do not worry about any of it:

•For  initial  use or start-up,  the  working time  of refrigerating system  will  be longer and  the noise  will 
be more  serious,  and  under the normal condition, you may  fi nd  out sound  like  liquid  fl ow,  which is 
caused by the circular fl ow of refrigerating fl uid within the tube;

•There might be a difference between the temperature displayed on the freezer and that at the center 
of freezer, that's because the sensor is not located at the center. However, the displayed temperature 
will gradually be closed to that at the center after stable operation of the freezer;

•For radiating tubes are equipped in the outer shell of freezer, the surface temperature of shell will be 
very high when the freezer is being operated.

• As the freezer is sensitive to the environmental temperature. The freezer cannot 
operate normally if it is installed in an environment other than the above. Please 
use it after improving the environment.

• It is prohibited to install the freezer in the open air environment. When the freezer 
gets wet in the rainwater, it may cause leakage of electricity or electric shock 
accident.

• Ambient temperature

:

10

℃

 to 32

℃

, with maximum beyond 32

℃

, the optimal temperature is 18

℃

 to 

25

℃

, the air conditioning system shall be used when necessary.

• Ambient humidity: below 85% Rh.

• Avoid large quantities of dust.

• Avoid mechanical sway or vibration.

• The altitude of freezer's working position: lower than 2000m.

• Input voltage: within the range of 220V±10%.

• Keep away from the radiated area and avoid the use of radiation-sensitive devices at its periphery.

For normal operation and optimum performance level of the freezer, its installation place shall 
conform to the following conditions:

• It can not be installed in a narrow, small and airtight space, the door frame of the room for placing 
it shall not be less than and lower than this product, and shall at least guarantee its normal passing 
in and out so as to avoid any maintenance diffi culty and failure of in-time repair in occurrence of 
machine fault, causing spoilage to the stored articles.

• The ground at the installation place shall be solid and fl at.

• It shall be well-ventilated without direct sunshine.

• Do not share a socket with other equipment, the plug and socket shall be well connected.

• Do not distort or stress the power cord.

• If it is required to lengthen the power cord, the section area of the lengthened wire shall not be less 
than 3mm

2

 and the length shall not be longer than 3m.

• Check the operating voltage before use, at the area where the voltage is not stable, use of a voltage 
regulator suitable for the motor load shall be considered for voltage stabilization. So that the normal 
input voltage is stabilized at 220V±10%, the power of the voltage regulator is greater than 4000W.

• The freezer shall be guaranteed with reliable earthing.

• If the power socket has earth wire, check if the earthing is good before use.

• If the socket is not furnished with an earth wire, be sure to install one by the professional 
engineering and technical personnel.

• Do not make freezer earthing via gas piping, water supply pipe, telephone line or 
lightning rod that may easily cause an electric shock.

• After installation, the power plug must be accessible to facilitate unplugging of the 
power cord in emergency. No articles shall block out the air vent of the freezer.
