3Pumped Refrigerant System Operation and Maintenance

Commissioning

After installation, verify that all components are working properly and that the equipment is ready to

begin operation.

Inspection Checklists

Initial Inspection Checklist

The initial inspection ensures that the equipment has been properly installed, the location of the

equipment has been properly prepared and the equipment is free of damage.

Note: Although it is not necessary for the RDU to be installed in a room with a vapor barrier,

the computer room should have one as a vapor barrier minimizes moisture infiltration.

Without a vapor barrier, it will be difficult to maintain the humidity in the room. Do not

introduce unconditioned outside air into the computer room.

Note: A minimum of 900 mm (36 in) of clear floor space in front of the RDU is required for

service access.

Ensure the installation procedure is complete according to the installation manual.

If the RDU is installed in the computer room, ensure that the walls, floor, and ceiling of the room where the

equipment is located are sealed with a vapor barrier.

Ensure there is no evidence of damage to the equipment.

Ensure the equipment is level.

Ensure that the equipment is joined to the adjacent racks if it is installed at the end of a row.

Ensure the clearance around the equipment is in accordance with local and national codes and regulations as

well as the installation manual.
