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. A one-
piece concrete slab with footings extended
below the frost line is recommended. Be sure
the foundation is level within 1/2" (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 28.

Clearances
Do not block the flow of air to and
from the condenser coil. Restricting
airflow or allowing air recirculation
will result in a decrease in unit
performance and efficiency because
discharge pressures are increased.
There must be no obstruction above
the unit that would deflect discharge
air downward where it could be
recirculated back to the inlet of the
condenser coil. The condenser fans
are propeller type and will not
operate with ductwork.
Install the unit with enough side
clearance for air to enter the coil and
for servicing. Provide service access
to the evaporator,
electrical control panel and piping
components.
Do not allow debris to accumulate
near the unit where it could be drawn
into the condenser coil.

free of snow or other obstructions to
permit adequate airflow for proper
operation.

The unit must not be installed in a pit or enclosure that is
deeper or taller than the height of the unit unless extra space
is provided. The minimum clearance on each
side of the unit is dimension "C" in table on this page.
