These tools are only a guide. Due to variations in room design, local climate
and occupancy, larger areas may require the use of multiple units to provide
the optimal cooling solution. Please consult your local authorized Friedrich
distributor or the Friedrich Technical Assistance team for sizing or
application assistance.
COOLING SIZING GUIDE
The cooling guide to the right is based on normal room insulation, average
number of sun-exposed windows and two-person occupancy.
HEATING SIZING INFORMATION
In heating mode, an energy efcient heat pump will generate slightly less
heating Btus than it would in cooling mode. However, in heating mode, heat
pumps use approximately 1/3 the energy of resistance heat, making them an
excellent high efciency alternative. Back-up resistance heat ensures heat
operation below 40� F outdoor temperatures for year ‘round comfort.
Common Window Types
Traditional wooden windows are typical in many residences built before
1965, but more modern windows are often constructed of aluminum or vinyl.
Many newer energy efcient windows like double-glazed windows actually
sandwich low conductance gas between two panes of glass. While Friedrich air
conditioners may be used with this type of window, care should be taken not to
break the seal between the two panes of glass during installation.
Depending on the style of window in the application, you may want to consider
the cooling solutions in the adjacent chart. Professional installers may be able
to make eld adaptations, including removing all or part of a window to support
alternative types of air conditioning units. Professional installers should also be
able to tell you about any local codes that may apply to your installation.
THRU-THE-WALL INSTALLATION
Many models may be installed through a wall so long as the unit’s side vents are
not blocked or covered in any way. See page 15, In-wall Installation max. depth.

The HIGHEST GRADE MATERIALS are used to
build a product that will perform reliably season
after season.
20 GAUGE STEEL cabinet will withstand years of
hard use.
SOLID SLEEVE TOP* keeps out falling debris,
which can obstruct the fan and prevent it from
turning, thus damaging the unit.
VIBRATION AND NOISE ISOLATING TECHNOLOGY
Like two resiliant rings on motor mount,
preventing metal-to-metal contact, that causes
vibration and noise.
SOLID STEEL BLOWER WHEEL HOUSING
Constructed from solid steel for maximum sound
reduction.
SCIENTIFIC REFRIGERATION DESIGN
For quieter performance.

SUPERIOR
COMPONENTS
RIFLED COPPER TUBING with greater surface
area for heat exchange, increases the efciency
of the coils, and improves the overall energy
efciency of the unit.
INSULATED PLENUM prevents outside air
intrusion.

ENTRYGARD
Steel retaining wire secures chassis to the sleeve
to deter ‘kick-in’ intrusion.
FIRM GRIP HANDLES make grasping the chassis
much easier during installation and removal.
ALUMINUM REAR GRILLE
protects the unit from damage

Superior components like ROBUST,
COMMERCIAL GRADE FAN MOTORS
that run at a lower temperature than
smaller fan motors prevent the unit from
overheating and contribute to a longer
