1.0 INTRODUCTION
1.1 Product Description and Features
The Liebert condenser is low-profile direct-drive propeller fan-type air cooled unit suitable for mounting outdoors. It provides for the heat rejection of either one or two separate refrigeration circuits,
matching heat rejection capacity varying with the outdoor ambient temperatures with each corresponding compressors heat rejection requirements. Constructed with an aluminum cabinet and a copper-tube aluminum fin coil, the unit is quiet and corrosion resistant. The condenser is quickly and
easily installed, because all internal wiring is completed at the factory with only electrical connections to be made at the job site. All electrical connections and controls are enclosed in an integral
weatherproof section of the condenser.
Figure 1 Liebert two-fan condenser
Introduction
1.2 Head Pressure Control Types
1.2.1 Fan Speed
Fan speed control utilizes a wave-chopper control to vary the air volume over the condenser coil,
based on refrigerant head pressure. The fan motor next to the electrical panel (two fans on 6-fan and
8-fan models) is a single-phase, permanent split capacitor motor with motor speed adjusted in
response to refrigerant pressure. The balance of fans on multi-fan units cycle on ambient thermostats.
The control system provides refrigerant head pressure control for outdoor ambients as low as
-20°F (-28.9 °C).
1.2.2 Variable Frequency Drive
VFD Condenser control system utilizes a variable frequency drive, inverter duty fan motor operating
from 0% to 100% motor RPM based on head pressure, sensed by refrigerant pressure transducers.
VFD, ambient-temperature thermostat(s), motor overload protection and electrical control circuit are
factory-wired in the integral control panel. VFD controls the fan adjacent to the connection end of the
condenser and remains energized with active compressor operation. The balance of fans on multi-fan
units cycle on ambient thermostats. This system provides refrigerant head pressure control for outdoor ambients as low as -20°F (-28.9°C).

1.2.3 Liebert Lee-Temp™ Refrigerant Control
The Liebert Lee-Temp head pressure control system is designed to maintain proper operating head
pressures in outdoor temperatures down to -30°F (-34.4°C). The condensers utilize head pressure control valves, extra refrigerant and insulated refrigerant receivers with heater pads. It works by flooding the condenser coil with liquid refrigerant to a level that balances the system condensing
requirements with the condenser coil surface available to reject the system heat. During the summer,
the system requires the entire condenser coil surface for heat rejection and most of the refrigerant is
stored in a receiver. In the winter, the same amount of heat can be rejected by only a fraction of the
coil surface. As head pressure begins to fall, the control valve restricts the flow of liquid refrigerant
exiting from the condenser. This extra liquid refrigerant reduces the effective condenser surface area
available for heat transfer. The head pressure control valve also bypasses hot gas into the receiver to
warm the liquid and maintain liquid pressure for proper operation of the expansion valve. Condenser
fan controls are either fan cycling on ambient temperature or constant on. Lee-Temp control is
required for Quiet-Line Condensers.
1.3 Sound Level Options
1.3.1 Standard Condenser
All Fan Speed and VFD Condensers are standard condensers with moderate operating sound levels.
Lee-Temp Condensers with standard-size coils matching Fan Speed and VFD coil sizes are standard
sound level condensers.
1.3.2 Quiet-Line Condenser
Introduction
Quiet-Line condensers can help your facility meet the strictest noise codes and do so at less cost than
traditional condensers with acoustical shielding. The Quiet-Line condensers utilize the same reliable
construction features of the standard condensers and have oversized coils and slower speed fan
motors which yield the required heat rejection needed at significantly lower sound levels. Lee-Temp
control is required for Quiet-Line Condensers.
1.4 Transient Voltage Surge Suppression Option
Transient Voltage Surge Suppression (TVSS) panel is standard in the VFD Condenser models only.
Surge protection is necessary because rooftop voltage supply often is not conditioned the same as the
voltage supply inside the data center. The TVSS is designed to protect sensitive electronic condenser
components from high voltage transients, up to 25kVA/phase.
An illuminated green LED indicates power supply is On and panel status is OK. An illuminated red
LED indicates conditions require service and the TVSS may require replacement to restore surge protection to the condenser.

2.0 SITE PREPARATION
2.1 Site Considerations
The condensers should be installed in a location offering maximum security and access for maintenance.
Avoid ground-level sites with public access and areas that contribute to heavy snow or ice accumulations. Utilize Piggyback condensers whenever interior building locations must be used. To ensure adequate air supply, Liebert recommends that condensers be installed in an area with clean air, away
from loose dirt and foreign matter that might clog the coil. In addition, condensers should not be
located near steam, hot air or fume exhausts. Also, the condensers should be located no closer than
3 feet (1m) from a wall, obstruction or adjacent unit.
The condenser must not be installed in a pit.
The condenser must be installed on a level surface to ensure proper refrigerant flow.
For roof installation, mount the condenser on suitable curbs or other supports in accordance with
local codes.
Lee-Temp receiver tanks should be mounted on the condenser legs for proper operation. Remote
mounting of tanks must be within 10 feet of the condenser—Contact Liebert Application Engineering
