Chapter 1 Overview
This chapter introduces the classification and models, model description, main components
and technical parameters of the Liebert condenser (condenser for short).
1.1 Classification And Models
The condenser is classified into two types: single circuit and dual circuit. The single circuit has
a set of discharge/liquid pipe to match the single refrigeration system of indoor unit. The dual
circuit has two sets of discharge/liquid pipes to match the two separate refrigeration systems
of indoor unit.
The condenser is available in 17 models. The classification and models are listed in Table 1-1.

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.

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
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
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.
