Hybrid Flex Inverter System
Zoned Mix and Match Flexibility

multi
18, 24, 36,000 BTUs

AOU18RLXFZ, AOU24RLXFZ, AOU36FLXFZ

Contractors can select either an 18, 24
or 36,000 BTU outdoor unit combined
with wall mounted, compact cassette or
compact duct type indoor units. Mix-andmatch flexibility of evaporator type and
capacity allows you to choose the indoor
unit that best fits the application, whether it
be hidden or showcased. These systems
are ideal for nursing homes, doctor's
offices, condominiums, apartments and
residences - any place where individual
cooling or heating is needed.

Features
l

Part of the Halcyon Hybrid Flex Inverter (HFI) Line
As part of the HFI line of components, indoor units
are compatible with other HFI outdoor units, meaning
mix and match capabilities with fewer components.

l

No Branch Boxes or Separation Tube Assemblies
While the 8-zone AOU48RLXFZ1 model requires both
branch boxes and separation tube assembly kits, the
smaller zoned units - AOU18, 24 and 36RLXFZ
do not require them.

l

Pricing Compared to Competition
Additional outdoor units provides better matched BTU 
capacity with indoor units. By better matching the
outdoor unit to the indoor capacity a better system value
is achieved.

l

High Efficiency Systems
Up to 18-SEER in efficiency, these units are 22%
more efficient than 14-SEER competing multi-zone
systems.

l

Why Choose an 18,000 BTU Zoned System?
A lower BTU dual zone is often the perfect solution to a
comfort need. A consumer shouldn’t have to purchase
a higher priced larger unit when only 14 to 18,000 BTU’s
are needed.

l

Connectable Capacity
Our 3 outdoor units provide systems from 14,000 to 39,000 BTU. Some connectable capacity is provided to allow
increased combinations and flexibility. All indoor units can operate at once, how ever if all the evaporators are
calling for cooling or heating at the same time it will decrease the capacity of each evaporator not to exceed the
condenser’s capacity. As zones meet desired set point the system’s other evaporators increase output up to the
evaporator’s rated capacity.

l

A Tri-Zone 24,000 BTU Unit
Fujitsu offers a 2-ton system that provides 2 or 3-zone
flexibility. By using connectable capacity, this system
allows up to three 9,000 BTU units.

For example: The load on a 3-bedroom home with a living room and kitchen downstairs and 3 bedrooms upstairs is
39,000 BTUs (21,000 BTU downstairs and 18,000 BTU upstairs). However the family isn’t upstairs and downstairs at
the same time, therefore not all units will be running simultaneously allowing 100% heating or cooling to occupied
spaces. This can be achieved by our AOU36RLFXZ outdoor unit.

RLS2 Designer Series Compatibility
Wall Mounted ASU9RLS2, ASU12RLS2, ASU15RLS2
Fujitsu’s indoor RLS2 models are now compatible with outdoor multizone units so contractors can choose between different wall mounted
styles as well as different evaporator styles (wall mounted, compact
cassette or compact duct).
Features:
l Sleek chassis design
l Energy Saving Program (ESP)

+ The filter can be used for approximately 3 years if it is washed with water when dirty to restore it's surface action.

Field Supplied Filters Used With Compact Duct Units

Filters are sized to keep velocities and
static pressure loss low. This will insure
sufficient static pressure is available for
ductwork, fittings and supply and return
grilles. lternative filter sizes with
equivalent face areas can be used.
After deducting filter loss, available
static pressure values are shown.
