When the compressor is started for the first time, it must be kept under the conditions of
34Hz,56Hz,82Hz for one minute (the overheating protection of the outdoor unit air-blowing
temperature, immediately decrease the frequency when the compressor is overflowing and
releasing the pressure) then it can be operated towards the target frequency. When the machine
runs normally, there’s no such process. After starting the compressor for operation, the
compressor should run according to the calculated frequency, and every determined frequency
for protection should be prior to the calculated frequency.
The speed of increasing or decreasing the frequency rapidly 1 -----------1HZ/second
The speed of increasing or decreasing the frequency slowly 2 -----------1HZ/10seconds

Remarks: Twh :the environment temperature of outdoor;
The above are the maximum frequency limitations of the complete appliance which are
affected by the environment, and they have nothing to do with the ability of the indoor unit.
