EcoBreeze System Installation8
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.
N
OTE: 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.
N
OTE: For 50 Hz models, use the pipe adapters to make the connections. See “Water supply
connection” on page 18.
Foundation
Provide a foundation for the EcoBreeze System as recommended in the submittal package.
Corner supports must have clamp connectors installed to secure the EcoBreeze Frame. See
“Position the EcoBreeze” on page 14. Intermediate supports must have vibration damper pads
installed on the top surface before the frame is placed on the permanent supports.
See EcoBreeze Frame Install Kit installation instructions for additional information.
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.
