This is the air conditioning anti-cold air function, to improve the comfort of the use of air conditioning, in the operation of the heating mode, to prevent the air conditioner from turning on the cold air, the R & D department of our company has made the air conditioning anti-cold air function Settings, the inner machine does not run first, the inner machine coil temperature reaches a certain temperature before starting to run, to ensure that the air is hot. The general duration is about 4-10 minutes, you can observe it first.

If there is no problem with the above inspection, professional network technicians will be arranged to serve you.

1) Sound of refrigerant flow when the outdoor unit is running or has just stopped running. This is a normal phenomenon of the machine.

2) The filter is dirty and blocked (the wind speed is large and small). Treatment method: Clean the filter.

3) Plastic parts thermal expansion cold contraction friction sound. Normal physical phenomena of plastic parts.

4) The outdoor unit makes a "poof" sound after running for a period of time. When the outdoor unit is converted into a defrosting state, the four-way valve reversing sound is a normal phenomenon.

5) Strong "file wind, is a normal phenomenon of the machine.

6) The hanging machine or cabinet panel is not tightly stuck, resulting in a vibration beating sound. Re-clamp

If there is no problem after the above inspection, professional network technicians will be arranged to serve you.

This is the process of air conditioning operation, the internal refrigerant state constantly changes, from liquid to gas, and then from gas to liquid. This normal physical phenomenon flows at a certain speed in the refrigeration system, due to a certain resistance, it will produce a "splash" of water, which is a normal phenomenon, especially in the dead of night is more obvious.

Due to the large temperature difference between the set temperature and the ambient temperature detected by the variable frequency air conditioner when it is just started, the compressor needs to operate at high frequency to improve refrigeration/heat, so as to achieve the purpose of rapid refrigeration/heat. When the compressor is operated at high frequency, the increase in the vibration frequency of the compressor will lead to greater sensory noise of the external machine. The smaller temperature difference between the set temperature and the compressor frequency will be reduced, and the noise will also be reduced. This is a normal phenomenon.

The air conditioner itself doesn't produce odor.

1、Generally, there has been no cleaning of the indoor unit filter and dust filter for a long time; There is no simple cleaning and maintenance of the indoor evaporator surface, leading to mildew, deterioration, and blowing out odor when starting and running.

2、When the new machine is just opened for heating, the indoor fan is not running, the indoor machine temperature is very high, and the plastic parts of the internal machine have a slight plastic taste after high temperature is normal. (The smell will disappear automatically after a period of use)

If there is no problem after the above inspection, professional network technicians will be arranged to serve you.
