CAUTION: Risk of contact with extremely hot and/or cold surfaces. Can cause injury. Verify that all
components have reached a temperature that is safe for human contact or wear appropriate, OSHA approved
PPE before working within the electric connection enclosures or unit cabinet. Perform maintenance only when
the system is de-energized and component temperatures have become safe for human contact.

service, and maintenance work must be performed only by properly trained and qualified personnel and in
accordance with applicable regulations and manufacturers' specifications.
NOTICE
Risk of passageway interference. Can cause unit and/or structure damage. The unit may be too large to fit
through a passageway while on or off the skid. Measure the unit and passageway dimensions, and refer to the
installation plans prior to moving the unit to verify clearances.
NOTICE
Risk of damage from forklift. Can cause unit damage. Keep tines of the forklift level and at a height suitable to fit
below the skid and/or unit to prevent exterior and/or underside damage.

concealed damage.
Damage should be immediately reported to carrier and a damage claim filed with a copy sent to Vertiv or to your
sales representative.
NOTICE
Risk of oil contamination with water. Can cause equipment damage.
Vertiv™ CoolPhase CDU systems require the use of POE (polyolester) oil. POE oil absorbs water at a much faster
rate when exposed to air than previous used oils. Because water is the enemy of a reliable refrigeration system,
extreme care must be used when opening systems during installation or service. If water is absorbed into the
POE oil, it will not be easily removed and will not be removed through the normal evacuation process. If the oil is
too wet, it may require an oil change. POE oils also have a property that makes them act as a solvent in a
refrigeration system. Maintaining system cleanliness is extremely important because the oil will tend to bring any
foreign matter back into the compressor.
NOTICE
Units should never be operated with no refrigerant charge, a holding charge, a proper load or without additional
oil as required added. Tag out system to prevent unauthorized personnel from accidentally starting equipment
and damaging compressors if any of these conditions exist.
