Mechanical Specifications
UniTrane Fan-Coil Mechanical Specifications
Performance Data
Capacity: Unit capacities are certified under Industry Room Fan-Coil Air Conditioner Certification
Program in accordance with AHRI Standard 440-97.
Safety: All standard units are UL listed in the United States and Canada and comply with NFPA 90A
requirements.
Construction
All Units
The unit includes a chassis, coil(s), fan wheel(s), fan casing(s), fan board and motor(s). Units also
include a noncorrosive, ABS main drain pan, positively sloped in every plane and insulated with
closed-cell insulation. Horizontal units and all units with standard piping packages also include a
thermoplastic auxiliary drain pan. Steel parts exposed to moisture are galvanized. The fan board
assembly and both drain pans are easily removable. The fan board assembly includes a quick-
disconnect motor plug. The chassis construction is 18-gage galvanized steel, and continuous
throughout the unit. The unit is acoustically and thermally insulated with closed-cell insulation. All
panels are made rigid by channel forming.
Vertical Cabinet and Slope Top Units
Front panel fabrication is 16-gage galvanized steel. All other panels are 18-gage galvanized steel.
The discharge grille is recessed to resist condensate formation. Hinged access door construction
is 20-gage steel and is flush with top panel.
Horizontal Cabinet Units
All panels are 18-gage galvanized steel, including the bottom panel. Discharge grille is recessed to
resist condensate formation. The hinged access door is flush with front panel. Bottom panels ship
with tamperproof screw fasteners and a safety chain.
Concealed/Recessed Units
Exposed panels on recessed units are 18-gage steel construction and ship separate from the unit.
Bottom panels on horizontal recessed models ship standard with tamperproof screw fasteners and
a safety chain. Horizontal recessed units feature a telescoping panel to allow the panel to be
adjusted to line up flush with the ceiling. The telescoping panel extends 1.25” to 2” depending on
the configuration of airflow.
Low Vertical Unit
Front panels are of 16-gage galvanized steel. All cabinet parts are made rigid by channel forming.
End panel is removable for piping access. Hinged access door construction is 20-gage steel and
flush with top panel.
Unit Finish
All cabinet parts and exposed recessed panels are cleaned, bonderized, phosphatized, and painted
with a baked powder finish available in six decorator colors. Standard finish meets ASTM B117
specifications (salt spray test).
Fans
The galvanized metal fan wheels are centrifugal forward-curved and double-width. Fan wheels and
housings are corrosion resistant. Fan housing construction is formed sheet metal. Low vertical
units utilize an aluminum tangential wheel design.
