Table 4
summarizes
responsibilities that are typically associated with the
RTHC chiller installation process.
Refer to the Installation Mechanical and Installation
Electrical sections of this manual for detailed
installation instructions.
q Locate and maintain the loose parts, e.g.
isolators, temperature sensors, flow sensors or
other factory-ordered, field-installed options, for
installation, as required. Loose parts are located
in the starter/control panel.
q Install the unit on a foundation with flat support
surfaces, level within 1/4” (6.35 mm) and of
sufficient strength to support concentrated
