4.1.3 Indoor Unit Installation Requirements

● If the actual server total load for each smart cooling product is less than 10%
of rated cooling capacity or the equipment room is not properly sealed, the
humidity in the equipment room may be too high, which is not a product
quality issue and should be dealt with by adding a dehumidifier.
● When determining the number of units, consider the redundancy design and
ensure that the redundancy design requirements in GB 50174 or TIA 942 are
met.
● Do not install the smart cooling product near a noise-sensitive place such as an
office or a conference room.

The inlet water pressure should be in the range of 0.1–0.7 MPa (a
reducing valve must be installed at the humidifier water inlet if the
inlet water pressure exceeds 0.7 MPa). If the inlet water pressure is
lower than 0.1 MPa, a check valve must be installed at the
humidifier water inlet. 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
The distance between the upper drainage of the water pump and
the cabinet installation floor should not exceed 4 meters.
