Users of air-conditioner are reminded that in hot summer, difference in indoor and outdoor temperature should not be too significant, and the former should be kept at 3 ~ 5°C lower than the latter, so as to ensure the health condition of human body.
2.
A refrigeration ton refers to the BTU of air-conditioner per hour. One refrigeration ton is about 12,000 BTU of heat transmitting from indoor to outdoor per hour. Before purchasing a suitable air-conditioner, consumer should consider the size and direction of room, as well as your budget.
3.

When the air-conditioner is not cool enough, please check whether:
A. the temperature is properly pre-set by the temperature adjuster;
B. heat-generating appliances, such as electric heater or gas appliances, are turned on in the room;
C. bright sunshine gets into the room.

Advantages of split air-conditioner:
A. Relatively quiet
B. Suitable for rooms without available space for the installation of air-conditioner.
5.
Do not clean the filter of air-conditioner by water with temperature above 40°C. Simply clean the filter with clear water or using soft brush to remove dirt. Do not use hot water for cleaning. Do not expose the filter directly to sunshine for drying; otherwise, the filter will be contracted and deformed due to high temperature. Filters should be examined every 7 ~ 20 days. If it is too dirty, it should be cleaned immediately, or else, room temperature cannot be lowered and causes wastage of power.
6.
Split air-conditioner is composed of indoor and outdoor units, ensuring a relatively quiet indoor environment. However, since the motor and compressor of split air-conditioner are installed outdoors, which has to be connected via copper pipe, professional technician should to be hired for installation.
7.

The temperature of air-conditioner should be set at 26°C ~ 28°C. According to statistical figures, by adjusting the temperature upward by 1°C , consumers can save 6% of power consumption of air-conditioner. For rooms that are visited frequently, indoor temperature should not be lower than the outdoor temperature by more than 5°C, so as to ensure the health condition of human body.
