Note
1. The installation holes are long and flat holes. It is recommended to use M10 × 20 bolts to fix the mounting base.
2. The upper condenser must be installed on a rack during vertical installation, and the cushion pads should be installed between
the condenser and the rack for reducing vibration. It is prohibited to stack two condensers through bolt connection.

Note*:
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
Note
When the equivalent distance between the indoor unit and the condenser exceeds 30m, refer to 5.1 Refrigerant Tubing System
in Liebert.PEX Series Air Conditioner Technical Manual for the requirement of the line equivalent length.

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
Outdoor temperature: -20°C ~ +45°C. Low temperature accessories are required if the temperature
is between -35°C and -20°C
Outdoor humidity: 5%RH ~ 95%RH
400V ± 10%, 50Hz
≤ 1000m. Derating is required if the altitude exceeds 1000m
Electrical control box: IP55; unit: IP20; fan motor: IP54
Table 1-6 Parameters of storage environment
Clean indoor environment with good ventilation and no dust
-40°C ~ +70°C
5%RH ~ 85%RH
The total storage time should not exceed 6 months. Otherwise, the performance needs to be
re-calibrated
