Water supply
The inlet water pressure should be in the range of 0.1–0.7 MPa (A
reducing valve must be installed if the inlet water pressure exceeds
0.7 MPa.), and the temperature should be in the range of 1°C–40°C.
The water should meet the following requirements:
Non-freezing and nephelometric turbidity units (NTU): < 3
No visible substances
6.5 ≤ pH value ≤ 8.5
Total hardness (in CaCO
3
): ≤ 450 mg/L
Drainage
The distance between the upper drainage of the water pump and the
cabinet installation floor should not exceed 4 meters.
Power distribution
Leakage circuit breakers are not recommended for the primary
route. If a leakage circuit breaker is required by the customer or by
local regulations, use the residual current circuit breaker (RCCB)
that is not sensitive to the single-phase DC pulses and transient
current pulses.
Note: If the requirements are not met, contact Huawei technical support for an optimized
solution.
