2.1.4 Installation Notes

To realize the designed performance and maximum product life, correct installation is vital. This section
should be used in conjunction with local industry standards for mechanical and electrical installations. Note
the following items:
1. The chilled water AC is designed for integrated floor installation. It should be installed on the floor of the
equipment room or computer room.
2. Before the installation, make sure that the installation environment meets the requirements (see 1.4
Environmental Requirements) and the building should be transformed to accommodate the construction work
of piping, wiring and ventilation ducts.
3. Follow the design drawings strictly when installing the equipment, and reserve the space for maintenance.
The engineering dimensions drawings provided by the manufacturer can serve as a reference.
