A1: In winter, when the temperature in the mainframe room is below 0℃, anti-freezing measures should be taken for the mainframe, chilled water pump, and cooling water pump piping system. 1, the host of anti-freezing: the host condenser, evaporator import and export valves closed, waterproof valve and venting valve open, and then the use of compressed air or nitrogen will be blown out of the residual water; 2, water pump and pipeline antifreeze: keep the freezing/cooling water valve and pipeline open, the lowest...

1. The central air conditioner must be turned off when it is not in use for a long time to save electricity; 2. After confirming that the central air conditioner needs to be shut down for a long period of time, carry out a comprehensive cleaning and maintenance of the air conditioner;

1, a long time is not with the central air conditioning, summer use, inside the sink is still part of the stock water, these stocks of water due to mold over time, the smell is blown out of the air, this problem, we can set the air conditioning mode of operation for the circulation of the wind mode, open the window, let the air conditioning run for about 30min, you can eliminate the smell. 2, when not in use for a long time, you can let the air conditioner open circulating wind operation...

Central air conditioning is used by the air conditioner to switch on and off control, air conditioning normal operation after turning on the air conditioner, the air conditioner will be able to operate normally in accordance with the selected mode of operation. Air conditioner for whatever reason and shut down, due to the general air conditioner are equipped with a time delay for the shutdown (delay time of about 3min), then this type of air conditioner can be turned on immediately after the shutdown, but need to be after 3min to run. But there is no time delay...

This phenomenon is normal. In winter, if the ambient temperature of the air conditioner is low, the air conditioner will warm up before working normally.

A1:Re-washable filters 1. Remove the air filter and gently flick it a few times or dust it with a vacuum cleaner. 2. Rinse the filter in a dish with clean water and blow dry in a cool place. 3. Install the blown-dry filter into the original place, the whole maintenance work is completed. A2: It is a disposable over...

1. Improper use and maintenance Solution: In the winter when using the central air conditioning heating should pay attention to the sealing of the house, observe the outdoor unit with or without frost, ice, do not force hot water for frost and ice, such as trouble should be timely contact with the Tianjin Bote Environmental after-sales department. Encounter failure should stop using and contact a professional central air conditioning repair personnel to check and repair. 2. Fluorine deficiency Solution: central air conditioning suspected...

1. When the heating frost will produce water, is a normal phenomenon. 2. Outdoor connection piping insulation is not in place when cooling, exposed, condensation will occur.

General use of two years of maintenance once, available non-flammable and non-corrosive gas blowing off the heat exchanger on the accumulation of dust, special harsh environment needs to increase the frequency of cleaning. Cleaning water temperature should not be higher than 40 degrees Celsius, and can not use gasoline and other corrosive, strong solvent cleaning. Check the central air conditioner how to maintain the power supply line, piping insulation sleeve, strapping whether there is broken, loose and other phenomena.

This is residual operation, which mainly dissipates the residual heat in the heat exchanger and thus serves to protect the equipment.

Moving the machine to a professional team in strict accordance with the correct norms will not affect the performance and life of the machine.
