NOTICE!
Risk of improper refrigerant charging. Can cause equipment damage.
Refrigerant charge must be weighed into air-cooled compressorized systems before they are started.
Starting compressors without proper refrigerant charging can cause the compressors to operate at
less than 5°F (
–
15°C) evaporator temperature and at less than 20 psig (138 kPa). Operation for
extended periods at less than 20 psig (138 kPa) can cause premature compressor failure.
NOTICE!
Risk of clogged or leaking drain lines and leaking water-supply lines. Can cause equipment and
building damage.
This unit requires a water drain connection. Drain lines must be inspected at start-up and periodically,
and maintenance must be performed to ensure that drain water runs freely through the drain system
and that lines are clear and free of obstructions and in good condition with no visible sign of damage
or leaks. This unit may also require an external water supply to operate.
Improper installation, application and service practices can result in water leakage from the unit.
Water leakage can result in catastrophic and expensive building and equipment damage and loss of
critical data center equipment.
Do not locate unit directly above any equipment that could sustain water damage.
We recommend installing a monitored fluid-detection system to immediately discover and report
coolant-fluid system and condensate drain-line leaks.
NOTICE!
Risk of doorway/hallway interference. Can cause unit and/or structure damage. The unit may be too
large to fit through a doorway or hallway while on 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.
NOTICE!
Risk of improper storage. Can cause unit damage.
Keep the unit upright, indoors and protected from dampness, freezing temperatures and contact
damage.
NOTICE!
Risk of improper maintenance. Can cause equipment damage.
Installation and service of this equipment should be done only by qualified personnel who have been
specially-trained in the installation of air-conditioning equipment and who are wearing appropriate,
OSHA-approved PPE."
