All units shall be factory assembled, piped, wired and fully
charged with R-410A. All units shall be certied in accordance
with ARI Standard 390 for Single Packaged Vertical Air Condi-
tioners and Heat Pumps. Units shall be ETL listed and carry a
ETL label. All units shall be factory run-tested to check opera-
tion and be manufactured by Friedrich or equivalent.
The basic unit shall not exceed 23

height of the unit from the bottom of the isolators to the top of
the duct collar shall not exceed 32 ¼" for models up to 12,000
Btu , 47 ¼" for 18,000 Btu models, and 51 1/4" for 24,000 Btu
models. The unit shall be designed so that the unit will insert
into a factory supplied wall plenum 2

sion. Factory supplied wall plenums shall allow for installation
through walls from 4 ½" – 14" in thickness. Wall plenums will be
adjustable to minimize installation clearances. Unit shall draw
in ambient air through upper portion of an outside architectural
louver measuring 25

" high and shall exhaust
heated air out through the lower portion of the louver. The unit
shall be secured to the architectural louver by means of a two
part, weather-resistant wall plenum. The unit shall be capable
of left, right or straight-in installations into mechanical closet
without eld modications.
REFRIGERATION SYSTEM – The refrigeration system shall be her-
metically sealed and consist of a rotary compressor that is exter-
nally mounted on vibration isolators no smaller than 1 ¾" dia. x 1 ½"
high; condenser and evaporator coils constructed of copper tubes
and aluminum plate ns; and capillaries as expansion devices. Unit
shall have a fan slinger ring to increase efciency and condensate
disposal. A primary condensate removal system consisting of ¾"
FTP ttings on multiple locations shall exist. A secondar y over ow
from the primary drain pan shall expel water to the outside of the
building through the wall plenum and louver in the event that the
primary drain line clogs.
AIR HANDLING SECTION – The condenser fan shall be driven
by a single BLDC fan motor for models up to 12,000 Btu. 18,000
and 24,000 Btu models shall utilize a separate motor for both
the indoor and outdoor air sections. Airow shall be directed
ver tically up through a standard 10" ex duct starter collar and
into exible or rigid ducts to be distributed into the conditioned
area on models up to 18,000 Btu. Starter collar shall have both
crimped edge to ease ex duct installation and a waistline to
prevent duct from loosening.
The chassis shall have a built-in damper capable of providing
up to 60 CFM of fresh air into the conditioned area. A ne mesh
screen shall lter the incoming fresh air. The damper can be
controlled by a slide lever located on the front of the unit.
CONTROLS – The unit shall be factory equipped with terminal
strip for connection to a standard 24-volt single-stage heat/
cool thermostat. A 24-volt transformer shall be included and
factory wired. Low voltage inputs will include: C (common), R
(24V power), Y (cooling), G (fan), W (heat) and B (reversing valve
on VHA heat pumps only).The unit shall be hard-wired and have
a quick-disconnect to disable power for control box service.
An emergency heat override switch must be available to allow
operation of the resistance heater in the event of a compressor
failure on heat pump models.
GENERAL CONSTRUCTION – The unit shall be constructed of
18-gauge galvanized zinc-coated steel. The unit shall feature
½" foil backed insulation for sound and thermal efciency.
The wall plenum (required factory accessory) shall be shipped
separately and constructed of 20-gauge galvanized zinc-coated
steel; pretreated with zinc-phosphate and sealed with a chro-
mate rinse, then powder-coated for maximum coverage and
protection. The plenum shall be black in color for minimal
visibility of unit from exterior of building. The plenum shall be
shipped with a protective weatherboard for use prior to nal
installation of the louver and chassis.
The architectural louver (required factory accessory) shall
be shipped separately and fabricated from extruded anodized
aluminum with louvers in the horizontal plane.
The unit shall include vibration isolators mounted under the
chassis and a nonrigid plenum-to-chassis connection to isolate
vibrations to the building.
The unit shall have a plastic fan, fan shroud and drain pan and
aluminum outdoor coil endplates for corrosion protection and to
help prevent rust on the side of the building below the outdoor
louver.
The unit shall be shipped with return air lter brackets and a
14" x 20" or 18" x 20" lter afxed directly on to the unit chassis.
Optional return air grilles and access panels shall be available
as factory accessories for installation in the wall or door of the
mechanical closet.
CORROSION PROTECTION - The unit shall feature corrosion
-resistant materials and nish to help prevent deterioration.
The outdoor coil shall have Diamonblue advanced corrosion pro-
tection consisting of hydrophilic-coated ns to prolong the life of
the coil in all applications including seacoast protection.
ACCESSORY ACCESS PANEL - An optional factory-supplied access
panel shall be available to provide access to the unit and adequate
return air. The panel shall feature a lter holder to accept a eld
supplied 25” x 20” x 1” lter. Kit shall contain a hinge bracket for
mounting the door with the return air openings high or low on the
door for optimal sound attenuation.
WARRANTY – The warranty is one year on all parts and labor
and 5 years on the sealed system, parts and labor, including
compressor, indoor and outdoor coils and refrigerant tubing.
