General Information
Installation Overview
For convenience, Table 2 summarizes responsibilities that are typically associated
with the CGWF/CCAF chiller installation process.
Refer to the Installation Mechanical and Installation Electrical sections of this manual
for detailed installation instructions.
• Locate and maintain the loose parts, e.g. isolators, flow sensors or other factory-
ordered, field-installed options, for installation, as required. Loose parts are
located in the starter/control panel.
• Install the unit on a foundation with flat support surfaces, level within 1/4” (6.35
mm) and of sufficient strength to support concentrated loading. Place the manu-
facturer-supplied neoprene isolators assemblies under the unit.
• Install the unit per the instructions outlined in the Mechanical Installation section.
• Complete all water piping and electrical connections.
NOTE: Field piping must be arranged and supported to avoid stress on the
equipment. It is strongly recommended that the piping contractor provide at least 3
feet (914 mm) of clearance between the pre-installation piping and the planned
location of the unit. This will allow for proper fit-up upon arrival of the unit at the instal-
lation site. All necessary piping adjustments can be made at that time. Refer to the
current engineering bulletin for further details on installation.
