Product manual

IOMM ACR/AGR-1 3
Introduction
IMPORTANT INFORMATION
This Product Manual contains information on three different McQuay product lines.
• Model AGR-AM This is the AGR packaged chiller but with the shell and tube
evaporator shipped loose for remote mounting. Liquid line specialties are field
supplied and mounted. Capacity control is included and is Johnson UNT as standard
or optional McQuay MicroTech Control. This unit would be the normal choice when
an indoor shell and tube water chiller and remote condensing unit with factory mounted
capacity control is desired. NOTE: AGR-AM type units are not included in the ARI
Certification Program.
• Model ACR-AS This is an air-cooled condensing unit for use with a remote
evaporator, typically a water chiller or DX coil. Neither capacity control, liquid line
specialties, nor evaporator are included. The ACR would be the choice when a DX
coil (air handler) is used with a remote condensing unit or if some control other than
the controls available on the AGR-AM are desired. NOTE: ACR type condensing
units are not included in the ARI Certification Program.
• Model CDE This is a DX evaporator that can be used in conjunction with the
Model ACR condensing unit. No controls or specialties are included.
