3.6 Daily operation inspection of unit
During daily operation, observe closely the following points:
1. Whether the temperature, sound and vibration of the running equipment normal, otherwise take the
neccessary steps to address them. Check whether the current and surface temperature of the running
equipment is normal.
2. Whether the outdoor ambient temperature is within the required range, otherwise it will be adjusted.
3. After the operation of the unit is stable, check whether the suction pressure and exhaust pressure are normal,
otherwise it should be adjusted.
4. Check whether the temperature and humidity in the room are within the normal range.
