Installation Preparation
The Liebert LPC range of air conditioners is streamlined for maintaining a favorable and
suitable environment for testing laboratories and similar testing ecosystems. Strict
adherence to the installation procedures is mandatory for appropriate installation of the
Liebert LPC air conditioners. In the previous section, we looked at the working conditions
which included the operating, storage, and technical specifications for the Liebert LPC
models. In this section, let’s look at the installation preparation before moving on to installing
the LPC system to simulate a real-time scenario.
2.2.1 Equipment Room Requirement
The equipment room must be prepared to ensure a smooth operation flow and obtain
accurate results. The equipment room must meet the standards for appropriate ventilation
and heating. The design specifications for the air conditioners must be apt and should
match the energy- efficient design standards.
Following are the requirements for maintaining a favorable room environment prior to
installation:
• The room should have suitable and effective heat insulation.
• The equipment room should have a sealed damp-proof layer. Polyethylene film should
be used for the damp proof layer of the ceiling and walls. Alternatively, moisture-proof
paint can be used to simulate the same effect akin to Polyethylene. Care should be taken
that the coating on the concrete wall and floor must be damp-proof.
• Outdoor air increases the load of heating, cooling, humidification, and dehumidification
significantly. Therefore, all the doors and windows must be closed. Gaps and seams must
be highly narrow to prevent the outdoor air from entering the equipment room. It is an
industry- best practice to keep the inhalation of the outdoor air below 5% of the total
indoor airflow. Take appropriate thermal insulation and antifreeze measures for outdoor
water pipes to avoid poor drainage and insufficient water supply caused by freezing.
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 so that it complies 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 LPC model.
2.2.2 Installation Space requirements
Air conditioners in the Liebert LPC range are advanced precision air conditioners and the
recommended way is to install them as standalone equipment.
• For servicing, repairs, and maintenance, it is imperative that adequate maintenance
