Safety Precautions and Measures
The important safety precautions and measures that should be followed during the installation and
maintenance are described in the following sections.
Read the manual prior to installation and operation of the unit. Only qualified personnel should move, install, or
service this equipment.
The user reads and considers all the precautions, compliance, and safety measures before working on
the equipment. The unit control must be used exclusively for the purpose which it is intended for; the
manufacturer takes no liability for incorrect use or a modification to the unit control.
Adhere to all the Warnings and Cautionary measures included in the manual.
Please read this manual carefully before installing, maintaining and troubleshooting; especially the
Warning/Danger/Caution information in the User Guide. Apart from the User Guide, also pay attention to
the warning labels on the unit and its components.
This manual is retained for the entire service life of the unit. The user must read all the precautions, danger,
warnings, and cautionary measures mentioned in the manual prior to carrying out any operations on the unit.
Each unit is equipped with an electric insulation which allows the users to work in safe conditions. The main
switch is positioned on the electrical panel cover; Open the right door to access it. Before any maintenance
operation, switch o the unit with this electrical insulation device to eliminate risks such as electrical shocks,
burns, automatic restarting, moving parts, and remote control. The panel key, supplied along with the unit,
must be kept by the personnel responsible for the maintenance. The protective covers can be removed after
the electric power has been cut o by opening the main switch.
In the following sections, notice the various cautionary measures and warnings that need to be read carefully
prior to installing or operating the system.
Disconnect the local and remote power supplies prior to working with the unit.
Prior to the installation process, read all the instructions, verify if all the parts are in place, and check the
nameplate to ensure the voltage matches the available utility power for the unit.
The controller doesn’t isolate power from the unit even in the O mode, and some internal components still
require and receive power during the O mode.
If the unit door is open while the fans are operating, the airflow may result in abrupt slamming of the door
resulting in injury. Another aspect is the presence of small objects in the fans bay which may result in object
ejection during the fan start-up and there is a probable risk of being hit by these objects leading to grievous
injury as well as causing equipment damage.
The unit contains fluids and gases under high pressure. Therefore, the pressure should be relieved before
working with the piping.

Some components can be extremely hot during the unit operation. Therefore, allow suicient time for the unit to
cool down before working with the unit cabinet. Handle the unit with extreme caution and wear safety equipment
such as protective gloves, safety shoes, and arm protection while working with the hot components.
There is a risk of leaking water that can cause damage to the equipment as well as the building. There should
be an eective water drain connection and facilities. Installation should be precise. Implementation of the
application and service practices should be suitable and fault-free. Not complying with these norms will result
in water leakage from the unit. Water leakage can result in massive damage and loss of critical equipment in the
hosting ecosystem. Therefore, care should be taken to ensure that the unit must not be located directly above
any equipment that could sustain damage due to water and excessive moisture. Using a leak detection system
for the unit and system supply lines are recommended by Vertiv Co.

Pre-Installation
Chapter 2: Pre-Installation
XDP precision air conditioner is a distinctly engineered equipment which requires preliminary preparation
before installation. This chapter provides the pre-installation details, including how to prepare the installation
environment, space and reserve the maintenance area. It also gives the air conditioner operational and storage
environment requirements, followed with the procedure to unpack the unit and placement strategies.
2.1.Equipment Room Requirements
The requirements are as follows:
1. Before installation, the equipment room must be prepared to ensure a smooth operating flow and to achieve
the expected results. The data center must meet the standards, to obtain proper ventilation and heating. The
design specifications for the air conditioners must be ideal and should be in-line with the energy-eicient
design standards.
2. To ensure the normal operation of environmental control system, the room should be moisture proof and the
equipment room should have a sealed damp-proof layer. Polyethylene film should be used for the damp proof
layer on the ceiling and walls. Alternatively, the same eect similar to polyethylene can be simulated with
moisture-proof paint. It is important to ensure that the coating on the concrete wall and floor is damp-proof.
3. The equipment room should be free of air leakage, reduced to a minimum because outdoor air can increase
the system load and de-stabilize the temperature gradient. It is recommended that the leakage rate of outdoor
air be kept below 5% of the total indoor airflow.
4. To avoid any outside air infiltration into the room, all the doors and windows should be properly closed.
• Avoid locating the indoor unit in concave or narrow areas which can aect the airflow. It is prohibited to use
the XDP precision air conditioner in an unconducive outdoor environment.
• Vertiv recommends that the site preparation is defined as per the requirements. However, if these
requirements are not met, Vertiv recommends that rectifications be made on the site in order to comply with
the specified requirements and conditions.
• However, if the rectifications or modifications are not implemented, then Vertiv does not guarantee the
accuracy and precision of the temperature and humidity provided by the unit.
2.2.Installation Space Requirements
The Liebert XDP consists of a cabinet that includes a heat exchanger, circulating pump (s), control valve,
receiver, controls, valves and piping. Cooling module can be chosen according to the application and to the
appropriate scenarios.
