Vertiv I Liebert Air Cooled Condenser I User Manual 6
1.4.3 Parameters of Operating Environment
Refer to Table 1-5 for parameters of operating environment.
Table 1-5 Parameters of operating environment
Item Requirement
Installation position
The standard equivalent distance between the indoor unit and the condenser
is 30m. Vertical difference* ∆H: -5m ≤ ∆H ≤ 20m. Installation mode: horizontal
or vertical mode
Ambient temperature
Outdoor temperature: -20°C ~ +45°C. Low temperature accessories are
required if the temperature is between -35°C and -20°C
Ambient relative humidity Outdoor humidity: 5%RH ~ 95%RH
Operation power 400V ± 10%, 50/60Hz
Altitude ≤ 1000m. Derating is required if the altitude exceeds 1000m
Protection level Electrical control box: IP55; unit: IP20; fan motor: IP54
Condenser fins have a corrosion resistant coating designed to provide maximum life expectancy for the heat
exchanger and protect the aluminium fins from harsh environments. The high performance coating has been
tested for 2000 hours exposure to a 5% neutral salt spray test in accordance with ASTMB117 without impact to the
coating
When the equivalent distance between the indoor unit and the condenser exceeds
30m, refer Refrigerant Tubing System in Liebert LSF Air Conditioner Technical
Manual for the requirement of the line equivalent length.
1.4.4 Parameters Of Storage Environment
Refer to Table 1-6 for parameters of storage environment.
Table 1-6 Parameters of storage environment
Item Requirement
Storage environment Clean indoor environment with good ventilation and no dust
Ambient temperature -40°C ~ +70°C
Ambient relative humidity 5%RH ~ 85%RH
Storage time
