Commissioning Checklists
Initial Inspection Checklist
Warning: Review the safety and data sheet (MSDS-Material Safety Data Sheet) for
R-22 for safe handling of the refrigerant.
The equipment operates under pressure — 276-2930 kPa (40-425 psi ). Take proper
safety precautions when connecting gauges or servicing the refrigerant/condenser loop
or chilled water piping.
Never operate this equipment with any cover, guard, door, or panel removed unless
instructions indicate otherwise and do so using extreme caution.
Electrical Hazard: Perform Lockout/Tagout procedures on the equipment being serviced.
Failure to remove power before servicing this equipment could result in serious injury or
death.
Caution: 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.
Do not introduce unconditioned outside air into the space.
Ensure that:
The installation procedure is complete according to the installation manual.
Walls, floor, and ceiling are sealed with vapor barrier.
Raised floor space (downflow only) beneath the equipment is a minimum of 18 in (457 mm).
Optional floorstands are installed correctly and that the equipment is secured to them.
Duct work is properly installed.
The equipment shows no signs of damage.
Clearance around the system is in accordance with ASHRAE, local and national codes and the
installation manual.
Shipped components (leak detection devices, firestats, smoke detectors, remote sensors, etc.) are
installed securely.
Any optional remote temperature and humidity probes installed are supported by the NetworkAIR FM
DX.
