Inspecting the Equipment
Inspect for missing components. All shipped loose components are identified by part number
and description on the bill of lading. Ensure each item is present before accepting delivery of
the unit.
Filing a claim. If damage has occurred, or if shipped loose parts are missing, report it
immediately to the delivering carrier and note the problem on the receiving copy of the bill of
lading. Failure to do so will result in replacement parts and repairs being billed to the customer.
In case of shipping damage, do not operate the equipment. Keep all packaging for inspection
by the shipping company and contact Schneider Electric.
Storing the equipment before installation
WARNING
DAMAGE TO EQUIPMENT OR PERSONNEL
• Do not remove tension rods until the EcoBreeze™ Frame is placed and secured on
its supports.
• Move the EcoBreeze Frame directly from the truck to its permanent foundation or
supports. If it must be stored temporarily, it must be placed on a flat and level
surface to avoid damage.
• Leave the protective plastic wrap in place until you are prepared to install the
equipment.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
Heavy: Ensure the lifting equipment has sufficient capacity for the load.

Site Preparation
Incoming power supply requirements
NOTE: This equipment requires three-phase electrical service. Electrical service must conform
to national and local electrical codes. The equipment must be grounded.
NOTE: To facilitate routing of main power supply wiring, run parallel wires for the main power
connections.
Ductwork
Provide supply and return ducting at the site to connect to the supply and return ductwork on
the EcoBreeze System.
See the ductwork drawings in submittal package for recommendations for ducting
sizes and supply and return duct configurations.
Water supply
Supply water requirements. The water supply must be clean, potable water. The inlet water
pressure provided to the unit must be between 207 and 448 kPa (30 and 65 psig). If the water
pressure available is less than 207 kPa (30 psig), a booster pump (not supplied) may be
needed to operate the equipment properly. If the water pressure available is higher than 448
kPa (65 psig), use an external pressure regulator (not supplied).
NOTE: Installation of back flow prevention and a water hammer arrestor is recommended.
NOTICE
DAMAGE TO EQUIPMENT
External water piping must have adequate freeze protection and must be correctly applied
based on local climatic conditions and best practices. Any exposed piping must be
electrically heat-traced and insulated (supplied by others).
Failure to follow these instructions can result in equipment damage.
Foundation
Provide a foundation for the EcoBreeze System as recommended in the submittal package.

Lifting and Rigging
WARNING
DAMAGE TO EQUIPMENT OR PERSONNEL
• Do not remove tension rods until the EcoBreeze Frame is placed and secured on
its supports.
• Before lifting the EcoBreeze Frame, ensure the lifting equipment is adequately
sized for the load.
• Lift and rig the EcoBreeze Frame from the top four ISO corners only.
• Move the EcoBreeze Frame directly from the truck to its permanent foundation. If
the Frame must be placed elsewhere temporarily, it must be placed on a flat and
level surface in order to avoid damage.
• Check for overhead obstructions such as power cables.
• Maintain a minimum safe distance while equipment is hoisted.
• Control access of personnel at lift site.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
EcoBreeze Frame. The EcoBreeze Frame is not equipped with forklift pockets. Lift and rig only
from the four upper ISO corner blocks on each EcoBreeze Frame using a crane.
Recommended horizontal sling angles are greater than 45 degrees. Lifting equipment must be
rated for at least 18 144 kg (40,000 lb) for lifting a 12.2 m (40 ft) Frame, and at least 12 247 kg
(27,000 lb) for a 6 m (20 ft) Frame.

Mechanical Connections
Install the EcoBreeze Frame per the EcoBreeze Frame Install Kit instructions.
Position the EcoBreeze
NOTE: The power and plumbing connections for the EcoBreeze Frame are located on the end
where the unpacking sheet is placed on the protective wrap. Typically this is the end that will
face the building.
1. Ensure that clamp connectors and vibration damper pads are installed per the
EcoBreeze Frame Install Kit instructions.
2. Use a crane with sufficient lifting capacity to place the EcoBreeze onto the permanent
supports. Typically the end of the frame with plumbing and power connections is placed
nearest to the building.
3. Using a 15/16-in. open-end wrench to turn the drive stud, lock down the clamp
connectors located at each of the four corners. Maximum torque on the drive stud is 68
N-m (50 ft/lb).

Unwrap the equipment
NOTICE
DAMAGE TO EQUIPMENT
• Do not remove the plastic wrap until the EcoBreeze Frame is placed on its
permanent supports and you are prepared to install the return air ductwork. If the
plastic is removed, ensure that the return air plenums on top of the Frame are
protected.
• When removing protective plastic wrap, be careful to cut only the plastic and not
damage the exterior of the equipment.
• The plastic wrap protects the return air plenum openings on top of the Frame until
the return air ductwork is installed.
Failure to follow these instructions can result in equipment damage.

Remote display interface
NOTICE
DAMAGE TO EQUIPMENT
Damage to LCD display will result from exposure to temperatures below 0°C (32°F).
Outdoor installations will require a third-party heat source as needed to ensure the LCD
display is not subjected to temperatures below 0°C (32°F).
Failure to follow these instructions can result in equipment damage.
See EcoBreeze remote display installation instructions for additional information.
The remote display interface enclosure contains the LCD display that is used to control the
EcoBreeze from a remote location. The EcoBreeze connects to the remote display interface
over an expansion bus.
NOTE: Separate incoming power cables from low voltage wiring by 150 mm (6 in.).
NOTE: Communication wiring from the EcoBreeze to the remote display interface enclosure
must be a minimum of 24-gauge, 3-core wire with shield with a maximum length of 300 m (984
ft).
1. Install the remote display interface enclosure in the desired location.
IMPORTANT: For outdoor applications, use weather-proof conduit connectors.
OPERATING CONDITIONS: Ambient temperature 0 - 55°C (32 - 131°F). Relative
humidity 5% - 95% non-condensing.
NOTE: Connect shield wire to GND.
2. Connect the bus wiring to the contacts labeled 124, 125, and 126 on the expansion bus
