NOTICE
Equipment Damage!
Failure to protect the unit from freezing could result in
equipment damage.
If fluid has been added to the piping, the unit must be
protected from freezing. Freeze damage from an
unheated equipment room is not the Trane company's
responsibility. These are indoor units.
NOTICE
AFD Component Damage!
Operating unit at ambient temperatures below 34°F
(1.1°C) or in excess of 104°F (40°C), or in excess of
95% relative humidity (non-condensing conditions),
could result in AFD component damage due to the
panel’s inability to dissipate heat adequately.
If any of these adverse operating conditions are
present, take necessary action to improve the
equipment room environment.
To ensure that electrical components operate properly, do
NOT locate the chiller in an area exposed to dust, dirt,
corrosive fumes, or excessive heat and humidity. The
ambient temperature range for chiller operation is 34°F to
104°F (1.1°C to 40°C).
Adaptive Frequency Drive Enclosure
Rating
The Adaptive Frequency™ Drive (AFD) cabinet has a
NEMA 1 enclosure rating:
NEMA 1: Vented. Intended for general-purpose indoor
applications.
Environmental Conditions
Important: Location of the Adaptive Frequency™ Drive
(AFD) is important if proper performance and
normal operating life is to be expected.
Therefore, unless designed for special
environments, the controller should be
installed in an area where the following
conditions exist
• Verify that NEMA1 enclosure drives can be kept clean
and dry.
• The area chosen should allow the space required for
proper air flow. Adequate clearance for air circulation
around the enclosure is a 6 in. (16 cm) minimum
clearance required wherever vents are located in the
cabinet.
• Be sure that the NEMA1 enclosure is installed away
from oil, coolants, or other airborne contaminants.
• Do NOT install the drive above 3300 ft (1005.8 m)
without derating output power. For every 300 ft (91.4 m)
above 3300 ft (1005.8 m), derate the output current 1
percent.
• Line frequency is 50 or 60Hz.
• Maximum elevation at which drive can operation is
9842.5 ft (3000 m).
• Non-corrosive location.
• Verify that the drive location will meet the
environmental conditions specified in the following
table.

Rigging
Lifting is the recommended method for moving chillers.
Suggested lifting arrangements for standard units are
described in “,”.
Note: The lifting beam used for HDWA Agility™ chillers
must be at least 12.5 ft (3.8 m) long.
Important: If unit must be disassembled for installation,
refer to Installation Instructions: Agility Chiller
Disassembly/Reassembly Units (HDWA-
SVN001*-EN) for instructions, including
weights and rigging instruction for
components.
Agility™ chillers should be moved ONLY by lifting at
designated lift points. Refer to the following instructions in
this manual for typical rigging arrangements.
WARNING
Heavy Object!
Failure to follow instructions below could result in
unit dropping which could result in death or serious
injury, and equipment or property-only damage.
Ensure that all the lifting equipment used is properly
rated for the weight of the unit being lifted. Each of the
cables (chains or slings), hooks, and shackles used to
lift the unit must be capable of supporting the entire
weight of the unit. Lifting cables (chains or slings)
may not be of the same length. Adjust as necessary
for even unit lift.
WARNING
Improper Unit Lift!
Failure to properly lift unit in a LEVEL position could
result in unit dropping and possibly crushing
operator/technician which could result in death or
serious injury, and equipment or property-only
damage.
Test lift unit approximately 24 inches (61 cm) to verify
proper center of gravity lift point. To avoid dropping of
unit, reposition lifting point if unit is not level.
