Chapter 2 Onsite Preparation and Installation
2.1 Precautions for installation
Note
When handling the unit, you must keep the unit vertical. It is prohibited to handle the unit
horizontally or upside down. Any damage caused to the unit for failing to observe this
instruction shall not be covered by the warranty.
Before installing the equipment, you should decide how to modify the building to facilitate
the piping, cabling and duct construction. Please install the units strictly according to the
relevant drawings. For the reserved installation and maintenance space, please refer to the
engineering dimension drawing provided by the manufacturer.
2.1.1 Storage and operation environment requirements of CyberMate series air
conditioner
For the storage and operation environment requirements of the CyberMate series air
conditioner, please refer to Table 2-1 and Table 2-2.

Note: If the relevant values in the actual application exceed the recommended values
in the above tables, please consult the technical department of our company.
2.1.2 Preparation of the computer room
Computer room shall have good insulation and a sealed moisture-proof layer. Ceilings and
walls shall be equipped with sealed moisture-proof layers.
The computer room shall minimize the entry of outdoor air, which will increase the cooling,
reheating and humidification load of the system. Therefore, it is suggested that the amount of
outdoor air intake shall below 5% of the total amount of indoor circulated air. All doors shall be
fully sealed and the sealed gap of the door shall be as small as possible.
2.1.3 Installation site tips
Warning
Since the equipment can generate condensate water, the lower precise equipment may be
damaged due to water leakage. Do not install the air conditioner above the precise equipment.
Drainage pipelines shall be provided at the installation site of the equipment, which will be
installed below the indoor unit.
To ensure the normal operation of the indoor unit, you shall try to select a spacious area as the
installation site of the indoor unit. Avoid placing it in a narrow place; otherwise it will affect the
air flow organization, resulting in air intake and return air short circuit and air noise. Avoid
placing it at the end of a recess or a long and narrow room. Avoid installing multiple units one

next to another closely, which can cause overlapped air supply flow between different units,
unbalanced load and the mode that heating and refrigeration of different units compete for
operation simultaneously. Do not add extra devices to the case (such as the smoke detector),
which will hinder daily maintenance and repair.
The schematic diagram of the air conditioning equipment installation location is shown in
Figure 2-1.
Fig.2-1 Installation position of CRAC
2.2 Mechanical parameters
Warning
You must strictly comply with the recommended installation and maintenance space
requirement of the relevant equipment.
You should decide whether to modify the building to facilitate the piping, cabling and duct
construction.

clearance of at least 400mm shall be maintained between the outdoor unit and the
wall, obstacle or adjacent equipment. The equipment shall not be installed at the place
where the snow may accumulate at the air inlet and outlet.
2.4.1.2 Fixation and connection of indoor unit
Dismantled the handling trays of indoor unit , and securely fixed the indoor unit on the
ground or stand.In order to ensure the normal operation of the unit, the entire unit must
be level.
