Installation
AAON equipment has been designed for
quick and easy installation. Startup and
service must be performed by Factory
Trained Service Technician.
General
F1 Series air handling units are designed as
heating, cooling or combination units for
indoor installation only. They are designed
for R-410A refrigerant only. Flexible
connectors are required on all duct
connections to minimize air leaks.
Locating the Unit
Placement of the unit relative to ductwork,
electrical and plumbing must be carefully
considered. Return air plenum or duct can be
mounted directly to the return air flanges.
Use flexible gasket material to seal the duct
to the unit.
Verify floor, foundation or suspension
support can support the total unit weight,
including accessory weights. Unit must be
level in both horizontal axes to support the
unit and reduce noise and vibration from the
unit.
Allow adequate space for piping access and
panel removal. To ensure proper access
for field service, maintain minimum
clearances for field piping and other
obstructions. Consult local building codes
for
additional
service
clearance
requirements. Condensate drain connections
are located on the access side of the unit.
Service and Installation Clearance
Before setting the air handling unit into
place, caution must be taken to provide
clearance for unit panels that must be
accessible for periodic service. These areas
contain
the
controls,
safety
devices,
refrigerant piping, shut-off valves and filter
access.
F1 series air handling units require a
minimum of 36 inches of service clearance
on the access panel side of the unit in order
to ensure room for removal, replacement, or
service of coils and other components if
necessary.
Note: An auxiliary (emergency) drain pan is
recommended for all applications where
there is a risk of water damage to
surrounding structure or furnishings. Refer
to local codes.
Floor Mounted Units
Make sure that the unit is level, and
mounted on a field-supplied platform with a
minimum height of 12” to allow for proper
fall on the condensate line. Other installation
provisions may be necessary according to
job specifications. F1 series air handling
