Environment Requirements
Operating humidity
≤ 95% RH
Altitude
0 m to 1000 m. The cooling capacity is derated when the
altitude is above 1000 m. For details, see Figure 3-43.
Storage temperature
–40°C to +70°C
Storage humidity
≤ 95% RH
a: When the ambient temperature is below 0°C, the NetCol5000-C needs to increase certain
concentration of ethylene glycol solution. For details, see Cooling Capacity Curve in
Proportion to the Glycol Solution Density.
Installation Requirements
Table 3-31 Installation requirements
Item
Installation requirements
Room
The room can be sealed well.
Width ≥ 0.9 m; height ≥ 2.3 m.
Main water inlet
⚫
Water pressure is 0.4 MPa.
⚫
Maximum water inlet temperature
a
is 20°C.
⚫
A Y-shaped strainer needs to be installed on the water inlet pipe, 20
filtration pores. The pH value of chilled water is 7.0–9.0.
Water supply of
humidifier
⚫
Water pressure ranges from 0.1 MPa to 0.7 MPa.
⚫
Water temperature ranges from 1°C to 40°C.
⚫
Transient flow is greater than or equal to 0.6 L/min.
⚫
The quality of supplied water must meet the requirements listed in
Table 3-32.
Drain water
⚫
The upper drainage height of the condensate pump should be 3.5
meters at most.
⚫
The hose can be used in a environment whose temperature is higher
than 85°C. (The requirement is only for the units with a humidifier.)
Power
Earth leakage circuit breakers are not recommended for mains. If earth
leakage circuit breakers are required by the customer or according to
local regulations, use the residual current circuit breaker (RCCB) that is
not sensitive to the single-phase direct current pulse and transient
current pulse.
a: Adjust the alarm threshold because a high temperature alarm will be generated if the
temperature is over 20°C.
