DUCTLESS SPLIT SYSTEMS
AIR CONDITIONERS | HEAT PUMPS
Ductless splits are an innovative and ecient alternative
to window and thru-the-wall units. They have the benets
of a central system, without the diculty and expense of
installing ductwork. These are only a few of the benets
of ductless...
Unobstructed window views.
No need to uninstall and store unit during the winter.
Independently-controlled zone cooling means up to four separate
indoor units working from a single outdoor unit.
Save money by turning ounits in unoccupied rooms.
Set room temperatures based on individual preferences, instead of
one-size-ts-all.
simple installation
Friedrich ductless split systems have the
advantages of a ducted installation without
the high material and labor costs. Absolutely
no ductwork is required, so most systems
can be installed and running in a few hours.
SEER ratings up to 19.0
All Friedrich ductless models exceed the
federal 13.0 SEER requirements. And, a full
one-third of our models have super high
ratings ranging from 16.5 to 19.0 SEER
signicantly outperforming 13 SEER product
on energy savings.
extremely quiet
Ductless systems keep the operating noise
of the condensing unit outdoors, while
the blower fan of the indoor unit remains
whisper quiet.
Like a central system, without the ductwork.

Easy to install. Exceptionally quiet.
Totally flexible.
The indoor unit and outdoor unit are
connected by refrigerant and power
lines, through a small three-inch hole
in the exterior wall.

multiple conguration choices
Over 20 single, dual, tri- and quad-zone systems provide a wide range of
heating and cooling options for even the toughest remodels, additions and
improvements. A new level of system exibility and control is at your ngertips
on Friedrich single and multi-zone systems.
advanced inverter technology
Inverter Technology lets you reach the desired temperature faster, maintain it
more accurately, and reduce energy costs. It eliminates constant compressor
start-ups/shut-downs
that traditional
technology requires
to maintain the set
temperature.
variable capacity
advantages
Inverter Technology
allows each system to
adjust capacity and
cooling output to
provide only the amount of cooling needed at a given time. For example, an
18,000 BTU/h system will operate even more eciently as a 15,500 if that is all
that’s needed.

Insulated line sets are available for all Friedrich split systems in 15 ft. and 35 ft. lengths. Each line set is equipped with flare nuts on both ends. Both liquid and
suction lines are insulated. Line sets can be joined together with field supplied double female connectors. Each system requires one line set for each indoor
unit installed. On multi-zone systems, line sets should be ordered based on individual indoor unit capacities not total system capacity. For example, a M18DYF
uses 2 line sets for 9,000 btu units, not 1 for the 18,000 btu product.
