This section provides the information which should be considered before installing the
compressor.
Below are the explanations of installation environment requirements, wiring requirements,
cooling water requirements, length of cables and flexible hoses, remote functions, and subsidiary
functions.
2.1 Installation Environment
Refer to Table 1-4 in Section 1 and check the installation environment and operating
conditions to ensure there is no problem. The environment should be free from
contaminants such as oil, coolant and other suspended solids. Compressor should be
installed in a space with enough ventilation to avoid suffocation in a case of helium
leakage.
Figure 2-1 shows the dimensions of installation space and levelness of the floor required
to maintain the performance of a compressor. The compressor should be installed on a
flat floor surface.
CAUTION
Clear the back, front and sides of the compressor to maintain cooling by natural air flow.
Also, a space of 500mm back and front of the compressor is needed for maintenance. Around
the power cable in the back, keep space for working easily. In addition, easy access to the
handle of main circuit protector (MCP) on the back must be ensured.
