1 INTRODUCTION
1.1 Product Description and Features
The Liebert MC condenser is a low-profile, direct-drive propeller fan-type air-cooled unit suitable for
mounting outdoors. It provides heat rejection for either one or two separate refrigeration circuits, matches
the heat rejection capacity corresponding with the outdoor ambient temperature and with each
corresponding compressor heat rejection requirements. Constructed with an aluminum cabinet,
galvanized steel frame and microchannel 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 1.1 Two-fan Liebert MC
1.2 Control, Fan Types and Features
1.2.1 Premium Efficiency Control/EC Fan
Premium Efficiency Controls and EC fans are matched to provide superior system energy efficiency. The
premium control board allows CANbus communication with the indoor unit’s Liebert iCOM® control. This
communication feature provides compressor run signals, condenser operating mode changes, condenser
alarm monitoring, simplified system charging procedures and outdoor temperature monitoring. The fans
are controlled by the premium control board using pressure transducer signals from the refrigerant
circuit and factory programming to control the refrigerant head pressure.
Vertiv | Liebert® MC™ Installer/User Guide | 11
The Premium Efficiency Control board on a Liebert MC with a dual refrigeration circuit adjusts the speed
of fans on each circuit to match each circuit’s head pressure conditions. On a Liebert MC with multiple
fans and a single refrigeration circuit, the premium control adjusts the fans to the same speed to maintain
head pressure. The control system provides refrigerant head pressure control for outdoor ambient
temperatures as low as -30°F (-35°C), provided that the total design range (from minimum to maximum) is
125°F (70°C) or less. For traditional DX applications, Liebert Lee-Temp™ kits are required only when the
design temperature ranges exceed 125°F (70°C) for standard match-ups and 115°F (65°C) for Liebert
Quiet-Line™ match-ups.
Anti-Freezing Operation
The EC fans must be operated periodically in cold weather to reduce the possibility of lockup due to ice
and snow accumulation. During periods of inactivity and outdoor temperatures below 35°F (1.6°C), the EC
fans will spin for at least 30 seconds every 15 minutes at 60% of the maximum fan speed.
Fan Reversal for Cleaning
The Liebert iCOM® can be used to run the Premium EC fans in reverse to clear loose debris from the coil
between scheduled coil cleanings. The fan reversal may be done manually or automatically based on a
user-programmed schedule. Automatic fan reversal interval occurs when the indoor unit is Off (BMS Off,
U2U network standby or Remote Shut Down [RSD]).
Low-Noise Feature
The low-noise feature allows setting the condenser fans to operate at a specified speed to reduce
operating noise at certain times. Special match-ups of premium condensers are available for applications
needing to meet stringent sound regulations. Lower sound levels are achieved by oversizing the
condenser, which decreases the maximum airflow and sound level produced by the condenser. This
feature requires special setup of the indoor unit. One or more Liebert Lee-Temp receivers are required.
The premium control has gain schedules that will override the user-defined low-noise schedule to prevent
a high-pressure condition from occurring.
1.3 Liebert Lee-Temp™Refrigerant Control
The Liebert Lee-Temp head pressure control system utilizes head pressure control valve(s), extra
refrigerant and insulated refrigerant receiver(s) with heater pads to assist system starting. The Liebert
Lee-Temp control system also maintains proper operating head pressures in outdoor temperatures below
the rating point of the Liebert MC control type. The system 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 the 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 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. Liebert Lee-Temp kit is optional for condensers and is field-installed.
Condenser control boards are factory-configured for Liebert Lee-Temp if they are ordered with Liebert
Lee-Temp receivers. They can be field-configured if a Liebert Lee-Temp system is added later.
Vertiv | Liebert® MC™ Installer/User Guide | 12
1.4 Surge Protective Device
An optional Surge Protective Device (SPD) can be field-wired to protect the condenser from power surges
that threaten sensitive equipment. The condenser’s electrical panel provides a terminal block to allow the
SPD to be wired in parallel with the high-voltage power. An additional low-voltage terminal block is
provided on condensers with Premium Control Boards to allow monitoring of the SPD alarm circuit.
ASCO 420™ Series surge protective device provides 50kA per mode of surge current protection. An
illuminated green LED indicates the SPD is On and operating properly. An illuminated red LED indicates
that the device may require replacement.
When both LEDs are Off, there is no power to the condenser, either from a power failure or because the
condenser disconnect is in the Off position.

2 SITE PREPARATION
2.1 Site Considerations
• Condensers should be installed in a location offering maximum security and access for
maintenance.
• Avoid ground-level sites with public access and areas prone to heavy snow or ice
accumulations.
• To ensure adequate air supply, Vertiv™ 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 be located no closer than 3 feet (1m) from a wall, obstruction or adjacent
unit.
• For roof installation, mount the condenser on suitable curbs or other supports in accordance
with local codes.
• Condensers must not be installed in a pit.
• Condensers must be installed on a level surface to ensure proper refrigerant flow.
• Use caution when installing condensers below the indoor unit. Condensers must not be
installed more than 15ft. (4.6m) below the indoor unit. Condensers with Liebert Lee-Temp™
receivers must be installed at or above the level of the indoor units to maintain proper
subcooling.
• Liebert Lee-Temp receiver tanks should be mounted on the condenser legs for proper
operation. Contact Vertiv™ Application Engineering Department for assistance with
applications requiring remote mounting of receivers.
• Condensers must be installed in vertical airflow orientation to maintain the electrical box’s
NEMA 3R rating.

preparing unit for installation.
WARNING! Risk of heavy condenser falling or tipping over. Can cause property damage,
serious injury or death.
Confirm that all components of the lifting system are rated for the weight of the condenser by
an OSHA Certified rating organization before attempting to lift and/or move the condenser. See
2.2 on page15 throughCondenser and option net weights—Large condensers on page17 for
the condenser weights.
CAUTION: Risk of contact with sharp edges, splinters and exposed fasteners. Can cause
personal injury.
Only properly trained and qualified personnel wearing appropriate safety headgear, gloves,
shoes and glasses should attempt to move, lift, remove packaging from or prepare unit for
installation.
NOTICE
Risk of interference with building doorways, openings and passages. Can cause unit and/or building
damage.
Refer to the installation plans and measure the unit and building opening before moving the unit to verify
clearances.
NOTICE
Risk of improper forklift handling. Can cause unit damage.
Keep the forklift tines level and at a height that will fit under the skid.
NOTICE
Risk of improper storage. Can cause unit damage.
Keep unit upright and protected from contact damage.
Vertiv | Liebert® MC™ Installer/User Guide | 27
3.1 Equipment Inspection
Upon arrival of the unit and before unpacking, verify that the labeled equipment matches the Bill of
Lading. Carefully inspect all items for either visible or concealed damage. Damage should be immediately
reported to the carrier and a damage claim filed with a copy sent to Vertiv™ or to your sales
representative.
If you have the seismic mounting kit, refer to Liebert Seismic Application—OptionalUnitConfiguration on
page99
3.1.1 Packing Material
All material used to package this unit is recyclable. Please save it for future use or dispose
of the material appropriately.
Figure 3.1 Equipment recommended for handling a Liebert condenser
3.2 Handling Unit on the Skid
Transport unit using a fork lift or a crane with sling and spreader bars.
Using a forklift
NOTICE
Risk of improper forklift handling. Can cause unit damage.
Keep the forklift tines level and at a height that will fit under the skid.
• Make sure the forks (if adjustable) are spread to the widest allowable distance to still fit under
the skid.
• Type of forklift used will depend on the terrain the unit is to be moved across during handling.
• Minimum forklift fork length:
• for 1-fan and 2-fan units—48” (1219mm)
• for 3-fan and 4-fan units—72” (1829mm)
• When moving the packaged unit, do not lift it any higher than 6" (152mm). If the unit must be
lifted higher than 6" (152mm), great care must be exercised and no one may be closer than 20'
(6m) to the lift point.
• Vertiv™ recommends lifting one end off the ground no more than 6" (152mm)and using the
forklift to push or pull the unit.
Vertiv | Liebert® MC™ Installer/User Guide | 28
Figure 3.2 Forklift position with 1- to 4-fan condensers
Using a Crane
• Vertiv™ recommends using slings rated for the unit weight.
• Spreader bars must be used for sling stability and to keep the slings from pressing against the
unit. Make sure spreader bars are wider than the unit.
• Place the slings near the ends of the unit, under the top deck boards of the skid.
3.3 Unit Storage
Store the condenser in the original packaging in an area protected from excessive dirt, debris and
contact damage until final installation.
3.4 Unpacking the Condenser—All Unit Sizes
CAUTION: Risk of contact with sharp edges, splinters and exposed fasteners. Can cause
personal injury.
Only properly trained and qualified personnel wearing appropriate safety headgear, gloves,
shoes and glasses should attempt to move, lift, remove packaging from or prepare unit for
installation.
Refer to Figure 3.3 on the next page for the following steps:
1. Remove the fence for domestic packaging (for export packaging, remove the crate).
2. Remove the exterior foam from around the unit and the electric box.
3. Remove the steel straps securing the unit to the skid.
4. Set the legs aside, but keep accessible if legs are shipped together with the unit.
• Depending on the number of fans, more or less steel straps may be removed at this step.
5. Remove corrugated panels covering the condenser’s coil(s).
6. Remove the bolts securing unit to the skid.
7. Remove the bolts securing the brackets to the unit and recycle the brackets.
