Application Data
Unit Placement
AGR 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.
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 entrance to the coil
and for servicing. Provide service
access to the evaporator, compressors,
electrical control panel and piping
components.
Do not allow debris to accumulate
near the unit where it could be drawn
into the condenser coil. Keep
condenser coils and fan discharge free
of snow or other obstructions to permit
adequate airflow for proper unit
operation.
Sound Isolation
The ultra-low sound levels for the AGR chiller is sufficient for most applications. However, there will
be applications where sound levels are an issue. Avoid locations beneath windows or between
structures where normal operating sounds may be objectionable. Reduce structurally transmitted sound
by isolating water lines, electrical conduit and the unit itself. Use wall sleeves and rubber isolated
piping hangers to reduce transmission of water or pump noise into occupied spaces. Use flexible
Figure 17, Clearances
The recommended minimum side clearance between two units is 10 feet (3048mm).
Distance less than 10 feet (3048mm) can result in air recirculation.

The minimum clearance to a side wall or building taller than the
unit height is 6 feet (1828mm) provided no solid wall above 6 feet
(1830mm) tall is closer than 8 feet (2438mm) to the opposite
side of the unit. (consult factory for special situations.)
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,
(consult factory) the minimum clearance on each side of the unit is
8 feet (2438mm) when installed in a pit.
