IMM AGS-2
Remote Evaporator
This section contains data that is unique to AGS-CM/B remote evaporator models
including:
• Refrigerant piping on page 49.
• Dimensions on page 51.
• Vibration isolators on page 58.
• Physical data on page 60.
Data common to both packaged and remote evaporator models are:
• Electrical data on page 32.
• Evaporator pressure drop, on page 25.
Piping Layout
Figure 26 shows the piping layout for one of the two refrigerant circuits for AGS units with
a remote evaporator. Note that the refrigerant specialties are field installed adjacent to the
evaporator. The outdoor unit, the evaporator, and a kit of refrigerant components are
shipped as separate pieces. The outdoor unit is shipped with an operating charge of
refrigerant. Refrigerant for the evaporator and field refrigerant piping is furnished by the
contractor and must be added in the field.
The location and size of the refrigerant (and water) connections are shown on the
dimension drawings beginning on page 51. Looking at the control panel, circuit #1 is on
the left, #2 on the right.
NOTE: All field piping, wiring, and procedures must be performed in accordance with
ASHRAE, EPA, and industry standards.
