Unit installation
86 ACZ / AGZ-BM IOMM ACZ/AGZ-3
Unit Mode settings can be:
1. COOL, normal setting used with chilled water air-condition applications.
2. COOL w/GLYCOL, used with low temperature glycol applications. It allows a lower LWT
setpoint to be used.
3. ICE w/GLYCOL, used with ice storage systems, allows changing from chilled glycol operation
to lower temperature ICE operation. In ICE, the unit runs at full load until the ICE setpoint is
reached, at which time the unit shuts off. A three-position switch wired to terminals #28 and
#38 initiates the change from glycol cooling to making ice. (See wiring diagram on page 48.)
4. TEST, for use by service technician for certain test procedures.

line is a reminder that the ON/OFF switch on
the front panel (FP) must be in the OFF position before the MODE can be changed. This prevents a
mode change while the unit is operating.
