Maintenance Guide
Before replacing the air conditioner, take measures to protect the floors in the cold aisle and
long aisle in the pre-fab. module.
Context
Do not replace an air conditioner on damp or rainy days. Keep the indoor environment clean
during the replacement.
When replacing the indoor unit of an air cooled in-row precision air conditioner, you only
need to perform operations in a cold aisle inside the pre-fab. module. For example, to replace
air conditioner A1 or B1 in Figure 4-12, you need to push cabinets A1, A2, B1, and B2 on
both sides of cold aisle A to the extremities towards the hot aisle, and replace the air
conditioner in cold aisle A. Similarly, air conditioner C1 or D1 can be replaced in cold aisle B.

Air conditioners are replaced in similar ways. This section uses replacing air conditioner D1
as an example to describe the replacing method.
When replacing an air conditioner, put aside the removed components, bolts, and other
materials, as they are needed in later replacement operations.
