How to use the electric heater and what to buy.
(1) Rooms using electric heaters should have certain thermal insulation conditions, and there should be no excessive tuyere connected with the outside world to avoid excessive heat loss.
(2) The electric heater should be placed in the corner, wall and other inaccessible places, with the back away from the wall 10 ~ 20 cm and away from flammable materials.
③ The far infrared electric heater is a short-distance heating device, and the general effective distance is 1 ~ 3m. Therefore, the effective distance should be considered when placing.
(4) After the electric heater is turned on, it will work for a period of time. When the room temperature rises to 18 ~ 20℃, the temperature control switch can be set to the low temperature position for heat preservation.
⑤ It is not advisable to boil water, hot rice or dry wet clothes on the electric heater. Electric heaters that are not used for the time being should be covered with dust-proof protective cover after cooling. Long-term use of electric heaters should regularly remove dust and stains. For heaters with fans and swing mechanisms, grease should also be added to bearings and running parts regularly.
Instructions for purchasing electric heaters
① When selecting an electric heater, attention should be paid to matching the capacity of the electric meter with the power of the electric heater.
When installing a 2.5-amp electric meter, the user should buy an electric heater with an input power less than 1000 watt, and must use a dedicated line and a dedicated socket. Generally speaking, a 6- 10 square meter room can use a 400-800 watt electric heater; 10 ~ 15 square meters room can choose 700 ~ 1500 watt electric heater.
② The environment of the heated space should be considered when selecting the electric heater.
The living room or larger room should choose a heater or a reflective electric heater that can shake its head; Restaurants or small rooms can choose reflective electric heaters or convection electric heaters. This kind of electric heater has concentrated heating and remarkable heating effect.
③ Decoration should be considered when choosing electric heaters.
Generally speaking, PTC ceramic heaters and desktop quartz tube heaters are more suitable for family rooms. This kind of heater has various shapes and strong decoration, especially the miniature heater can be used as a pendant or desk decoration, which has good ornamental value.
④ Attention should be paid to safety when choosing electric heater.
Oil-filled radiator heater should be used in bedroom or bathroom, because it has no exposed electric heating elements and strong insulation performance, and sundries and water will not be immersed in the electric heater, and human contact will not cause burns. Families with old people and children should choose wall-mounted electric heaters, which can prevent children from putting flammable materials into them and causing fires, or the old people and children accidentally fall and touch the electric heaters, causing injuries.
Maintenance skills of electric heater
After driving for a period of time, there is a layer of foreign matter and dust on the surface of the heater water tank. If it is not cleaned, it will affect heat dissipation. After long-term operation, the blower motor should be maintained and replaced. This operation process must be judged and maintained by professionals. It is not allowed to disassemble the motor without permission, which will easily lead to short circuit and non-rotation of the motor, which will seriously lead to harness burning and fire. The ventilation pipe of the motor cannot be disassembled, which may easily lead to overheating and burning out of the motor. The variable speed resistor can shift the motor. If you use the first gear and the second gear for a long time, it is easy to burn out the resistor and affect the normal use. If this problem is found, it should be replaced in time. After the operating system is used for a long time, the control cable is prone to aging and deformation, resulting in inflexible or inadequate operation. Don't move it rigidly to avoid damaging the parts. If you find this problem, you should go to the maintenance station for judgment and repair and replace it according to the specific situation. Ventilation pipes, namely 1 hose and heater hose 2, are prone to aging and cracking due to long-term use at high temperature. If problems are found, they should be replaced in time to avoid water leakage, resulting in excessive water temperature and deformation of engine cylinder head. Replace the hose with the hose matched with Li Xia's car. The inferior hose is not corrosion-resistant.
The device should pay attention to the following points in use: when the temperature is lower than 0℃ in winter, there will be a layer of ice and frost on the front windshield. Start the engine. When the water temperature rises above 40℃, put the control in the defrosting position according to the sign and put it in the indoor circulation position. Turn on the blower motor and put it in the third gear position. At this time, the motor has the highest speed and runs for 3-5 minutes. Then according to the defrosting situation, you can put the gear in the first gear and the second gear. In the meantime, the driver had better not leave the cab. If the motor does not rotate, he should immediately return the motor gear to the closed position to avoid burning the variable speed resistor. When the outside temperature is low and there are many drivers and passengers in the cab, the glass will frost. You can put the control in the defrosting position and outdoor circulation position, and the motor can be put in the first or second gear, so that defrosting can be done. When there is no dust outside, you can put the circulation outside to make the cab air fresh. If there is sandstorm or the weather is too cold, put the circulation indoors to prevent sandstorm and dust from entering the cab.
