Inspection Checklists
Initial inspection checklist
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.

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.
Ensure that:
The installation procedure is complete according to the installation manual.
The walls, floor, and ceiling of the room where the cooling unit is located are sealed with a vapor barrier.
