Item Specications
Water supply requirements The inlet water pressure should be in the range of 0.1–0.7 MPa (a
reducing valve must be installed at the humidier water inlet if the
inlet water pressure exceeds 0.7 MPa), and the temperature should
be in the range of 1°C–40°C.
The wet lm humidier uses tap water and does not require an
additional water treatment device at the water inlet. The water
requirements are as follows:
● Non-freezing and nephelometric turbidity units (NTU) < 3
● No visible substances
● 6.5 ≤ pH value ≤ 8.5
● Total hardness (in CaCO3) ≤ 450 mg/L
Drainage requirements The distance between the top drainage of the water pump and the
cabinet installation oor should not exceed 4 m.
Power distribution
requirements
Leakage circuit breakers are not recommended for the main power
supply route. If a leakage circuit breaker is required by the customer
or local regulations, select the residual current circuit breaker
(RCCB) that is insensitive to single-phase DC pulsation and transient
impulse current.
Note: If certain conditions are not met, contact Huawei technical support.
