Commissioning
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.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe electrical work
practices. See NFPA 70E or CSA Z462.
• This equipment must be installed and serviced by qualified personnel only.
• Turn off all power supplying this equipment before working on or inside the equipment.
• Always use a properly rated voltage sensing device to confirm power is off.
• Replace all devices, doors, and covers before turning on power to this equipment.
Failure to follow these instructions will result in death or serious injury.
WARNING
MOVING PARTS HAZARD
• Do not operate the cooling unit with any cover, guard, door, or panel removed unless the
instructions indicate otherwise. Then, proceed with extreme caution.
• Do not run service utilities in front of the fan outlets.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
CAUTION
HAZARD OF HIGH PRESSURE REFRIGERANT OR EQUIPMENT DAMAGE
• Use R410a refrigerant only.
• Use hose and manifold set suitable for R410a with a minimum pressure rating of 50 bar
(725 PSIG).
• The unit display should be used to obtain pressure readings.
Failure to follow these instructions can result in injury or equipment damage.
NOTICE
HAZARD TO EQUIPMENT
• The 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 space.
Failure to follow these instructions can result in equipment damage.
InRow SC Operation and Maintenance4
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.
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.
There is no evidence of damage to the cooling unit.
The cooling unit is level and joined to the adjacent racks or secured to the floor.
The clearance around the cooling unit is in accordance with local and national codes and regulations as
well as the installation manual.
Electrical inspection checklist
The electrical inspection verifies that all electrical connections are secure and correct and that the cooling unit
is properly grounded.
WARNING
ELECTRICAL HAZARD
• Electrical service must conform to local and national electrical codes and regulations.
• The equipment must be grounded.
Ensure that the:
Incoming voltages match the phase and voltage listed on the nameplate.
Electrical wiring complies with local and national codes and regulations.
Cooling unit is properly grounded.
Electrical connections are tight, including contactors, terminal blocks, controllers, switches, relays,
auxiliary devices, and field connections.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
5InRow SC Operation and Maintenance
Mechanical inspection checklist
The mechanical inspection verifies that all mechanical components and connections are secure and tight and
ready for start-up and system charging. The inspection ensures that field piping is properly installed to promote
oil return to the compressor.
NOTICE
HAZARD TO EQUIPMENT
Improperly installed piping may result in improper operation and possible damage to the
cooling unit or surrounding equipment.
Failure to follow these instructions can result in equipment damage.
Ensure that the:
Fans are turning freely and that the blades are not distorted or bent.
Condensate drain line is at least the size of the drain connection.
Mechanical connections are tight, including compressor and receiver connections.
Ceiling tile adapter is secured to the building structure with properly-sized safety wire.
Covers and guards are in place.
