Installation requirements
Item
Specifications
Equipment room door
Width ≥ 0.9 m; height ≥ 2.3 m
Floor
Bearing capacity ≥ 350 kg/m
2
; height of the raised floor ≥ 250
mm
Installation mode
Installed on a concrete floor, a base, or an ESD floor
Pipe and cable routing
Cables and pipes can be routed from the top or bottom
Equivalent length of
one-way pipe
≤ 80 m
Height difference
between the indoor and
outdoor units
If the outdoor unit is placed higher than the indoor unit, the
maximum vertical distance between them is 20 m.
If the indoor unit is placed higher than the outdoor unit, the
maximum vertical distance between them is 5 m.
Thickness of the thermal
insulation foam
≥ 13 mm
Inner diameter of the
thermal insulation foam
Liquid pipe: 16 mm
Gas pipe: 19 mm
Drainage
Drainpipes can withstand a high temperature greater than or
equal to 85°C (for the smart cooling products configured with
electrode humidifiers)
Power supply
Leakage switches are not recommended for the main circuit. If
leakage switches are required by the customer or local
regulations, use the residual current circuit breaker (RCCB)
that is insensitive to the single-phase DC pulses and transient
current pulses
Note: If some conditions are not met, contact Huawei technical support.
Water Quality Requirements for Wet Film Humidifiers
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 wet film humidifier should use tap water (no water treatment facility needed for the inlet
water) that meets 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
