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.
- Do not install the smart cooling product near a noise-sensitive place such as an office or a conference room.

Water supply |
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:
|
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. |
Space Requirements
- Before installation, verify that the installation environment meets the requirements and whether reconstruction is required for routing water pipes, cables, and ventilation pipes.
- Install the indoor unit according to the design drawing and reserve space for maintenance. At least 1200 mm maintenance space must be reserved in front of or at the rear of the indoor unit, and at least 600 mm maintenance space must be reserved at the other end, as shown in Figure 4-3.
- Ensure that the equipment room provides good heat insulation, and the walls and floor are dampproof.
- Take measure to avoid damaging cabinet components and cables during cabinet transportation.
- To ensure good ventilation, check that the indoor unit is not placed in the corner of a room or at the end of a long and narrow room.
- Check that all doors and windows of the equipment room are closed to reduce the workload of the smart cooling product during system operation.
Precautions for Connecting Refrigerant Pipes
Pipe length mentioned in this document is equivalent.
When selecting the refrigerant pipes, note the following:
- Avoid elbows and ensure that the connection between the indoor and outdoor units is the shortest.
- After determining the best pipe route between the indoor and outdoor units, calculate the number of the components that cause local resistance loss, for example, elbows, and convert them into the equivalent length to straight pipes.
- The total length of pipes connecting the indoor unit and outdoor unit (L) equals to the equivalent straight length of elbows and connectors plus the length of the straight pipes connecting the indoor unit and outdoor unit.
- Pipes cannot be routed from the bottom on a concrete floor.
Precautions for Connecting Cables
- Connections of all power cables, control cables, and ground cables must comply with local electrical regulations, and the cable specifications should comply with local cabling specifications.
- For details about current in full load, see the device nameplate.
- Only qualified electrical installation personnel are allowed to connect cables. Before connecting cables, wear insulation and protective equipment, such as protective gloves.
- All smart cooling products must be reliably grounded.
- Cables cannot be routed from the bottom on a concrete floor.
