Application Data

The following is a user's guide in the application and
installation of Millennium Chillers, and will ensure the reli-
ability and trouble-free life for which this equipment was
designed. while this guide is directed towards normal,
water-chilling applications, the Johnson Controls sales
representatives can provide complete recommendations
on other types of applications.
Location
Millennium Chillers are virtually vibration-free and gen-
erally can be located at any level in a building where
the construction will support the total system operating
weight.
The unit site must be a floor, mounting pad or foundation
which is level within 1/4" (6.4 mm) and capable of sup-
porting the operating weight of the chiller.

Sufficient clearance to permit normal service and mainte-
nance work should be provided all around and above the
unit. Additional space should be provided at one end of
the unit to permit cleaning of evaporator and condenser
tubes as required. A doorway or other properly located
opening may be used.
The chiller should be installed in an indoor location
where temperatures range from 40°F to 110°F (4.4°C to
43.3°C).
water Circuits
Flow Rate –
For normal water chilling duty, evaporator
flow rates are permitted at water velocity levels in the
heat exchangers tubes of between 3 ft./second and 12
ft./second (0.91 m/s and 3.66 m/s). Condenser flow rates
are permitted between 3.33 ft./sec. and 12 ft./sec. (1.01
m/s and 3.66 m/s). Variable flow applications are possible,
