Yearly Maintenance
Table 8-4 lists yearly maintenance items for the indoor unit.
Calculate the total cooling capacity and total server load of the running smart cooling products. If the total load exceeds 80% of the total cooling capacity of the smart cooling product, Huawei recommends increasing the number of smart cooling products.

Troubleshooting |
|---|---|---|
Sensor |
Use a precision T/H sensor to calibrate the T/H sensors inside and outside cabinets. |
If the temperature deviation is greater than 1°C or humidity deviation is greater than 5%, the T/H sensor must be calibrated or replaced. |
Evaporator |
The evaporator fins are not pushed down. |
Use a fin brush to organize the fins that are pushed down. |
Welding point and needle valve |
Check that the welding spots and needle valves do not leak using soapy water, or check that they are free from oil stains. |
If leaking points are found, retrieve the refrigerant and weld the leaking points again. For details, contact Huawei technical support. |
