Location
Unit Placement
ACZ units are for outdoor applications and can be mounted on a roof or at ground level. Set units
on a solid and level foundation. For roof-mounted applications, install the unit on a steel channel
or I-beam frame to support the unit above the roof. For ground level applications, install the unit
on a substantial base that will not settle. A one-piece concrete slab with footings extended below
the frost line is recommended. Be sure the foundation is level (within 1/2” [13 mm] over its
length and width). The foundation must support the operating weights listed in the Physical Data
Tables on pages 16 and 17.
Since its operation is affected by wind, the unit should be located so that its length is parallel with
the prevailing wind. If this is not practical, field fabricated wind deflectors may be required.
Service Access
Each end of the unit must be accessible after installation for periodic service. Compressors, filter-
driers, and liquid line solenoid valve are accessible from the end of the unit. Motor protector
controls are on the compressor. Most operating, equipment protection, and starting controls are
located in the unit control box.
The fan deck with the condenser fans and motors can be removed from the top of the unit.
