Installation
Figure 1-3 Crane Lifting
• Before lifting., please to ensue the liting capacity of the equipment is greater than the weight of the
unit, refer the weight of the unit in the Technical Specication as per model number.
• There are two holes in each of the front and back bottom beams for xed lifting ropes, and the lifting
ropes need to go through the beam opening. The user can also use a cord or other method to x
lifting ropes here, to prevent the rope sliding during the lifting process.
• It is prohibited to install lifting bolts in other parts of the unit frame bottom. When installing the lifting
equipment, it is necessary to shelter the surface and ns of the unit, to avoid scratching.
• The warning board should be utilized in work area, it is prohibited to non-relevant personnel to enter.
• The lifting of units is a dangerous operation, which must be a responsibility of the skilled technicians
and avoid the non-professional personnel to operate.
• If high wind speed is identied on site, please stop lifting work, until it is back to normal.
1.1.2.Unpacking
Remove the frame package and foam of the condenser without removing the protection cardboard of the ns.
The protection cardboard of ns and the cushion pad of U tube located at the end of the condenser should be
removed after the condenser is in its installation position.

Vertiv | Liebert LVC | User Manual 8
Installation
• Do not touch the copper pipes to avoid distortion and system leakage, while moving the condenser
manually.
1.1.3.Inspection
After the product arrival, you should check the accessories against the packing list. If any parts are found
missing, or damaged, please report to the local oices of the carrier and Vertiv Co. immediately.
1.2. Installation Notes
The installation notes of the condenser are as follows
1. To ensure the heat dissipation capacity, install the condenser in the place with suicient airow. Do not
install it where the coil of the condenser may be obstructed by dust or snow. Ensure that there is no
steam of waste heat around.
2. The condenser must be installed on the ground of outdoor or other room that should be mounted on a
plain surface. It can be an elevated installation by concrete column or steel I-beam, it is required that the
installed base bearing capacity must be 1.5 to 2 times more than the weight of the condenser.
3. To reduce the impact of noise around the environment, the condenser should be installed away from the
residential areas (≥15 m).
4. Be careful not to damage the waterproof layer of the building, when the condenser is installed on the roof
of the building. Please observe the relevant rules of local premises.
5. Position the condenser higher than the indoor unit to ensure normal oil return.
6. Follow the vertical upward installation direction. For the convenience of installation and maintenance,
please install the No.1 system (as shown in Figure 2-4) on the same side of same row (as shown in Figure
2-5 & 2-6)
7. When the condensers are installed front-and-back side by side, please install the same height condensers
(as shown in Table 1-2) in a place (as shown Figure in 2-7) to avoid return airow short circuit.
8. If the condenser is installed in the place where children are accessible, a fence must be installed to restrict
the entry around the condenser.

1.3. Space Requirements
• A 4000mm clearance is required around the condenser air outlet.
• At least 1250mm service space is required on one side of the condenser.
• The engineered mounting bracket requires four sides to be hollowed out, which can be ventilated freely.
In the following Figure 2-8 & 2-9. “h” is engineered mounted bracket height “h1” is enclosure height, “a” is the

distance between the condenser and envelope, “b” and “c” is the distance between two condensers.
• It is recommended to install the No.1 system on the same side (as shown in Figure 2-5 & 2-6) to convenient
installation.
• If condensers cannot move to the installation location at one time as per site situation, it is required to
reserve adequate distance between condensers before second installation.
• The condenser needs suicient installation and service space around the installation place. And the specic
space requirements are shown in Figure 2-8, 2-9 & 2-10 and Table 2-1 & 2-2.
Figure 1-8 Spread evenly installation space required
• In Figure 2-8 the space requirement is based on the area of the building to provide the minimum spacing for air
circulaon within 10 m around the installaon site. If the air circulaon is not sucient, please consult Verv
personnel for technical conrmaon.

Installation
1. When the condensers are installed side by side, at least 0.5m engineered mounting bracket
height is required, which can increase the return air area and reduce the wind resistance.
2. When the condensers are installed side by side, the distance between the adjacent condensers
is reserved about 30mm, so the condenser can be lifted out for maintenance.
3. Figure 2-10, when multiple condensers are installed side by side, it is suggested that the width of
1300mm is reserved for every 6 condensers for maintenance.
4. The space requirement of condensers is based on enclosure height less than 1m in
Table 2-1 & 2-2. If enclosure height more than 1m, it is must to increase engineered mounting
bracket height. Please consult Vertiv personnel for technical conrmation.
5. The maximum number of side by side condenser which can be installed is 10.
1.4. Installation Procedures
• Before commencing any copper-pipe welding process, release all Nitrogen charges from the
indoor and outdoor units.
1.4.1.Installing Pipelines
• Protect copper pipes from any surrounding heat sources. Separate the copper pipes from structures
or other obstacles using rigid supports. Avoid dust and water vapor to entered in copper pipes.
• Use a good quality, silver-based solder for all brazed connections. Use refrigeration grade copper pipes
and ttings throughout the installation. Remove all Nitrogen from pipes during brazing to prevent
oxidation.
1. Location of gas and liquid pipe: The location of gas and the liquid pipe is shown in Figure 2-11. The
location parameters of each model are listed in Table 2-3.

2. Identify the outer diameter of gas and liquid pipe: Refer to installing unit pipes in ‘Liebert Indoor Air
Conditioner User Manual’ for pipe outer diameter.
3. Identify the condenser installation height: Refer to installing unit pipes in ‘Liebert indoor Air Conditioner
User Manual’ for installation height.
4. Install the pipes: Install the pipes according to the actual situation and national codes and standards.
• If the indoor unit is dual system unit, it is required to connect the gas and liquid pipe of the same
indoor unit No.1 system and condenser No.1 system, connect the gas and liquid pipe of same indoor
unit No.2 system and condenser No.2 system.
• If indoor unit is a single-system unit, it is required to number the condenser and indoor unit respec-
tively. This will avoid gas and liquid pipe connection error. Such as No.1 indoor unit connected with
No.1 condenser No.1 system, No.2 indoor unit connected with No.1 condenser No.2 system.
• According to the actual situation, plan the condenser installation location and reduce the distance
connected with the pipe of indoor unit.
1.4.2. Connecting External Power
1. Identify the cable specications
A condenser has two systems. It is required to the condenser No.1 system and No.2 system to powered supply
respectively. Select the appropiate power supply cables (L1/L2/L3/N/PE) and control cables (two core wires) of
the condenser according to the Full Load Current and the Installation Distance as shown in Table 2-4.
