APC ACSC100 User Manual

Electrical Hazard: Perform Lockout/Tagout procedures on the cooling unit before 
servicing the cooling unit. Failure to remove power before servicing this equipment could 
result in serious injury or death. 

After installation is complete, verify that all components are working properly and that the cooling unit 
is ready to begin operation.

The initial inspection ensures that the cooling unit has been properly installed, the location of the cooling 
unit has been properly prepared, and the cooling unit is free of damage.

Warning: The cooling unit operates under pressure. Take proper safety precautions 
when connecting gauges or servicing piping.
Warning: Do not operate the cooling unit with any cover, guard, door, or panel removed 
unless the instructions indicate otherwise. Then, proceed with extreme caution.
Warning: Do not run service utilities in front of the fan outlets.

Caution: The vapor barrier minimizes moisture infiltration. Without a vapor barrier, it will 
be difficult to maintain the humidity in the room.
Caution: Do not introduce unconditioned outside air into the space.

Note: A minimum of 900 mm (36 in) of clear floor space in front of and behind the cooling 

unit is required for service access. To roll the cooling unit out of the row, there must be a 
minimum of 1200 mm (48 in) of clear floor space in front of or behind the cooling unit. 
Out-of-row service requires 760 mm (30 in) of side clearance in addition to the front and rear 
clearance.
