Unit Placement

AGZ units are for outdoor applications and can be mounted
either on a roof or at ground level. 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. Use a one-piece concrete slab with footings extended
below the frost line. Be sure the foundation is level within 0.5"
(13mm) over its length and width. The foundation must be
strong enough to support the weights listed in the Physical
Data Tables beginning on page

Air Clearance
The Daikin Applied advanced "W" coil design and open air-
passage ends allow very close unit spacing and a small
installation footprint. The AGZ-E fans are canted inward and
reduce recirculation by directing discharge air to the center of
the unit, reducing the tendency to flow outward and spill over
into the coil inlet.
Sufficient clearance must be maintained between the unit and
adjacent walls or other units to allow the required unit air flow
to reach the coils. Failure to do so will result in a capacity
reduction and an increase in power consumption. No
obstructions are allowed above the unit at any height.
Spacing Requirements
In general, with a small performance penalty in some cases,
AGZ-E units can be spaced at four feet from other units or a
wall. Curves on the following pages give the minimum
clearance for different types of installations and also capacity
reduction and power increase if closer spacing is used.
