Ductless mini-split systems are a great solution to a wide variety of installation challenges, giving
contractors the ability to put air conditioning (and heat with heat pump models) in locations that
previously seemed impossible. They’re ideal when installing ductwork is difficult, prohibitively
expensive, or simply impractical. Both residential and commercial structures, new construction
and existing buildings, are candidates for mini-splits.
Basically a mini-split does away with the need for ductwork. Like a regular split system A/C or
heat pump, the condenser is located outdoors; one or more air handlers are placed indoors. The
two are connected by electrical, refrigerant, and condensate drain lines that run through a small
hole in an exterior wall, generally 3” in diameter or less.
In addition to eliminating the need for ducting, one of the other big advantages of mini-split
systems is true zone control. The air handler is dedicated to the room being conditioned and
is controlled by a wireless remote. That room can be kept at a temperature and humidity level
different from the rest of the house or building.
Multi-zone systems for two, three or four rooms (or one large space) feature a single condenser
that handles two, three or four air handlers. Each air handler is independently controlled, with its
own remote and electronics-based climate controls to regulate temperature and humidity levels,
as well as air flow. Units in a bedroom and a home office, for instance, can be programmed
for different hours of operation with the 24-hour timer, or two classrooms situated side by side
can be set at different temperatures.
Mini-split systems have the flexibility to fit virtually anywhere and with SEER ratings up to 20.0,
they’re also economical to operate.
Where can you use a mini-split? Common applications include:
nHistoric homes (the aesthetics of the
exterior are maintained)
nHomes with hydronic heat
nResidential additions such as a
sunroom or bedroom
nVacation homes and cabins
nSchools (individual classroom control)
nChurch sanctuaries and fellowship halls
nNursing homes and hospitals

Advantages of a ductless mini-split system
Quiet Operation—The operational sound of the compressor and fan is kept
outside with the condensing unit and the indoor air handler is designed to be
exceptionally quiet
Easy Installation—All it takes to connect the outdoor condenser and the indoor
air handler is a hole about 3” in diameter to run refrigerant lines, condensate
drain and electrical wires between the two components
Efficiency—Units are designed to be energy efficient with high SEER ratings that
meet or exceed government mandated standards; and only the room or area being
used is conditioned, potentially decreasing electricity usage when compared to
traditional systems
Attractive Appearance—High wall models feature a low profile indoor unit in
a neutral color that blends with any décor; ceiling cassettes also come in a neutral
color that virtually disappears in ceiling installations
Security—With a room air conditioner, there’s always the worry that access to
the home can be gained through the window where the unit is mounted; that
worry is eliminated with a ductless system
Consistent Comfort—Electronic climate controls regulate operation to maintain
a preset temperature level; random swing air flow (on most units) continually
adjusts the fan speed and air direction for a gentle, breeze-like effect
Simple Operation—One fully featured remote is included for each indoor air
handler, making it simple to select the mode, set the temperature and the timer,
and change the airflow direction
Mini-Splits and Indoor Air Quality
According to the EPA, the air inside our homes is often more polluted than
outside air. What’s needed to protect yourself from airborne contaminants
is a high quality filtration system, and that’s just what you get with all
ductless mini-splits from Century .
In fact, our “V” Series inverter units are equipped with triple filtration:
• Ionizer—removes microscopic particles from the air
• Active carbon and dust filter—removes dust, smoke, and pollen
• Air freshening filter—helps freshen the air
Additionally, the units can be operated in the dehumidification mode without
cooling or heating. This removes excess humidity from the indoor air, one of
the keys to preventing the growth of mold, mildew and other contaminants.
There’s more to comfort
than just temperature…

Cooling without Ductwork
A ductless mini-split air conditioner works the same way central air
conditioning does with one big difference—there’s no ductwork.
Both the central system and the mini-split can be classified as
split systems because they consist of an outdoor condensing
unit and an indoor air handler. With a central A/C system, the
indoor components include a cooling coil and an air handler (the
furnace’s blower or a separate air handler) that circulates the
conditioned air throughout the structure by way of the ductwork.
The mini-split indoor unit functions as both the indoor coil and
the air handler, delivering conditioned air directly into a single
room without sending it through any ductwork.
Heat Pump Models
A heat pump mini-split operates in basically the same manner,
but adds heating capability. In the summer it transfers heat
from inside the home to the outdoors. A reversing valve makes
it possible for the unit to reverse this procedure during cold
weather, absorbing heat from the outdoors and transferring it
indoors (yes, there is warm air outside, even when it’s below
freezing).
Heat Gain/Loss
One of the advantages this “ductless” operation provides is
efficiency. In a central system, the cooler air absorbs heat as
it travels through the ductwork. The longer the duct run, the
greater the temperature gain. In winter, heat can also be lost as
the conditioned air travels through the ducts.
Don’t forget that it takes air pressure to move the conditioned air
through the ducting system and that involves some noise from
the fan and the actual movement of air. A mini-split system,
however, is ultra-quiet because it doesn’t have to push the air
through many feet of ductwork.
Indoor Air Handler
How does a
mini-split
work?
This diagram shows a typical
single zone installation:
n The condensing unit is
installed outdoors while
the air handler is mounted
inside on an exterior wall.
A hole approximately 3” in
diameter is drilled through
the wall. The lines that carry
refrigerant from the air
handler to the condensing
unit and back run through
this hole.
n An electric line runs between
the two components: power
is supplied by the outdoor
unit so there are no cords and
plugs visible on the interior. A
bracket mounted to the wall
supports the air handler, but
is hidden by air handler.
n A drain line runs from the
air handler to the outside to
carry condensate away.

Inverter Technology:
Taking comfort and efficiency
to the next level
Century’s “V” Series ductless mini-split
heat pumps maximize comfort by reducing
temperature fluctuations and at the same
time save an estimated 40% or more
on energy consumption, compared with
traditional mini-split systems.
What’s different about the “V” Series?
It uses state-of-the-art inverter
technology.
An inverter is an electrical
device that varies the
frequency of the power
going to the compressor.
This allows the compressor
to run at variable speeds so
that it can precisely match the power with
the demand.
A microprocessor adjusts the compressor
speed by sampling the ambient air
temperature in the room or space
being cooled or heated. At start up,
the compressor runs at high RPMs to
quickly reach the desired temperature
in the room. Then it slows down to
a low rotation speed to maintain the
temperature. However, during times of
high demand such as weather extremes,
or even a large gathering in the room,
the compressor ramps up to a faster
speed to meet the demand.
Compare this to a traditional system
which cools by running the
compressor until the
setpoint is reached and
then turns off. This
on-off cycling results in
temperature fluctuations
that affect comfort, and
also adds to wear and tear of
the components.
Temperature isn’t the only contributor
to comfort: humidity is critical. Dehu-
midification, especially during hot, muggy
weather, is an integral component of
cooling. When the compressor in a tra-
ditional system cycles off, dehumidifica-
tion also stops. With an inverter system,
excess moisture in the air is removed all
the time because the unit runs constantly,
although mostly at “economy” speed.
Ductless mini-splits can save you money when it comes to adding
on to your house. If your current HVAC system is correctly sized to
your existing structure, it may not have the capacity to handle the
new square footage. Rather than replacing the entire system, you
can cool and heat your new space with a mini-split—and save the
cost of installing ductwork.
5
Advantages of
Inverter Technology
n Reaches the desired
temperature quickly
n Provides precise temperature
control and continuous
dehumidification (cooling mode)
n Extends component life by
eliminating on-off cycling
n
Operates exceptionally quietly
because the DC compressor
runs mostly at low speed,
which also reduces any
vibration and associated noise
n Saves energy by matching
the compressor speed to
the demand; rated at up
to 20.0 SEER
n Extra heating capacity even at
low ambient temperatures

When you need to
condition more than
one space, it’s not
necessary to install
separate systems. You
can choose multi-zone
models that let you
cool and heat multiple
rooms, and with our
InverterFlex models,
you can mix and match
2, 3 or 4 air handlers
to best match your
room requirements.
Each system uses one
outdoor condensing
unit tied to multiple
indoor units, and
each of the indoor
units is independently
controlled to meet
specific comfort requirements.
InverterFlex units make zoning
practical and economical. No
complicated systems and controls
are required to cool and heat
individual rooms. Setting the
desired comfort level is a snap,
using the wireless remote that
comes with each indoor air handler.
This makes them ideal not just
for residential use, but also for
nursing homes, classrooms,
anywhere individual comfort
control is preferred.
The multi-zone design is also ideal
for large spaces. One or more
InverterFlex systems can be effective
(and quiet) for a church sanctuary
or fellowship hall, school commons
area, even a warehouse setting,
for example. As with all mini-splits,
there’s minimal disruption for
Multi-Zone
Flexibility
A ductless mini-split can contribute to a better night’s rest by making
your bedroom more comfortable. You can control the temperature
and humidity levels separately from the rest of the home and select
Sleep Mode, if you choose. For most people, body temperature drops
as they sleep so the room setting that was comfortable at bedtime
is too cool by early morning. The Sleep Mode automatically adjusts
the temperature during the night so you don’t wake up looking for a
blanket or have to get up to change the thermostat.

installation and the sleek indoor
units blend into the décor.
As for operating costs, the units use
inverter technology for efficiency,
but you may choose to heat/cool
only the room or space being used,
saving even more on utility bills.
Capacities for InverterFlex models
range from 18,000 BTUH to 36,000
BTUH, with indoor air handlers sized
from 9,000 to 12,000 BTUH per zone.
You can see how one outdoor condenser is used in conjunction with multiple
indoor air handlers in a single structure. Air handlers can be installed up to
82’ (depending on model) from the condenser, so you can place the condenser
in the best location for your landscaping.

What do we mean by ‘Energy Efficient’?
In recent years, heating and cooling manufacturers have made significant
advances in the efficiency of their systems in terms of energy usage. This is an
especially important purchase consideration as fuel prices continue to rise.
Cooling efficiency is measured by a Seasonal Energy Efficiency Ratio (SEER)
rating. The higher the number, the more efficient the equipment. All Century
systems meet or exceed the federally mandated 13.0 SEER rating, and some
are rated as high as 20.0!
For heat pump models, efficiency is shown by a Heating Season Performance
Factor (HSPF). This is an estimate calculated by dividing the seasonal heating
output by the seasonal power consumption in watts. The federal minimum
is 7.7; the most efficient heat pumps have an HSPF between 8 and 10. Our
units are rated as high as 9.5 in the ‘V’ series.
All heating and cooling equipment comes with an Energy Guide label which
shows the estimated energy usage—you can use these labels to compare
equipment efficiency. Your dealer can help you determine which system is best
for you, taking into account a number of factors including the average number
of yearly cooling and heating days in your area of the country, in addition to
your individual needs.
All Century ductless mini-splits come charged with R-410A, an
environmentally friendly refrigerant.
Why is this important? Because R-410A doesn’t contribute to depletion
of the earth’s vital ozone layer.
The ozone layer is located in the stratosphere, providing a
protective barrier against the sun’s harmful ultraviolet rays
which can cause skin cancer and cataracts in people. UV
rays can also affect animals and crop yields.
In the past, most refrigerants were compounds
that contained chlorine—chlorofluorocarbons or
hydrochlorofluorocarbons. You don’t have to remember
these long names, but you should be aware that when these kinds
of refrigerants are released to the atmosphere, the chlorine molecule
combines with one of the ozone’s oxygen molecules, destroying ozone
at a faster rate than it can be replenished.
Soon all CFC and HCF refrigerants used around the world will be
replaced by non-ozone depleting types such as the R-410A that’s
already in use in all our mini-split models.

Owners of historic homes will appreciate the comfort and convenience of ductless
mini-splits. Adding air conditioning to older homes can be expensive and difficult,
while window units destroy the exterior appearance of the home. But with a
mini-split, the outdoor condenser can be located where it doesn’t detract from
the curb appeal, and simple conduit containing refrigerant and electrical lines is
inconspicuous. Remodelers and renovators will appreciate these same qualities.

Comfort and energy efficiency combine in these
attractive wall mount mini-splits. Rated as high
as 20 SEER, they include all the advantages of
advanced inverter technology.
You’ll find that your room reaches the preset
temperature quickly and that the temperature is
constant, without the variations that occur in other
types with on-off cycling. Because the units run
at low frequency most of the time, energy usage
is kept to a minimum. However, during weather
extremes (or when you have a room full of people),
the compressor ramps up automatically to maintain
the comfort level.
“V” Series units are exceptionally quiet. Heavy duty
compressors in the condensers are not just efficient,
but they also reduce noise and vibration. Inside,
the balanced fan circulates large volumes of air at
minimal noise levels.
Applications
Single zone models are especially suited to one
room residential installations such as bedrooms,
sunrooms, additions and workshops. For large
spaces up to 1550 square feet such as offices,
conference rooms, common areas, etc., the 24,000
BTUH models deliver big capacity with exceptional
efficiency. The inverter technology automatically
matches the power delivered with the load
requirements for precise temperature control.
Low Ambient Operation
The low ambient feature allows cooling when
outdoor temperature falls below freezing—great
for temperature/humidity sensitive environments.
Additionally, a factory installed crankcase heater
keeps compressor oil warm and reduces heat loss
to ambient air.
Low Ambient Operation: cooling 5° – 122° F,
heating 5° – 93.2 ° F.

‘V’ Series
Our InverterFlex multi-zone units let you
condition two, three or four rooms—or one
large space—with just one outdoor unit. The
contractor can design a system that best meets
the load requirements of each room being
conditioned because indoor air handlers can be
mixed and matched.
A single outdoor condenser is sized for multiple
indoor air handlers. These 9,000 and 12,000
BTUH indoor units can be mixed, up to the
point that their combined capacity reaches the
total system capacity—see the chart on the
following page.
InverterFlex models incorporate all the advantages
of inverter technology. The compressor speed is
variable, depending on the load demand. Most
of the time the unit runs at low RPMs, saving
energy while maintaining comfort, but ramping
up to higher RPMs when needed. Temperature
fluctuations and compressor on/off cycling are
eliminated, and indoor air quality is enhanced
because air is constantly being pulled through
the filters and dehumidified.
True zone control is possible
because each air handler operates
independently. InverterFlex systems
are also great for larger spaces such
as fellowship halls and commons
areas: install one or more units for
quiet, efficient, easily controlled
comfort.
Features
nZone Control—Each air handler is independently
controlled, can be set for individual preferences or
turned off when the room isn’t being used
n
Random Swing—Continually adjusts air direction for
a gentle, breeze-like effect preferred by most people
nMultiple Modes—Cooling, dehumidification only,

nLow Ambient Operation—cooling 5° – 122° F,
heating 5° – 93.2 ° F
nAuto Operation—Automatically selects the mode

nMulti-Stage Filtration—Includes ionizer to
remove microscope particles, active carbon
and dust filter, and freshening filter for
improved indoor air quality
