Heat Exchanger — stainless steel  
General  
Condenser Coil —  
tubes. Free floating design.  
All units shall be factory assembled, piped,  
internally wired and fully charged with  
refrigerant. All units shall be designed to  
operate at outdoor ambient temperatures  
as high as 115°F. Cooling capacities shall  
be rated in accordance with A.R.I.  
The Spine Fin™ condenser coil shall be  
continuously wrapped, corrosion resistant  
all aluminum with minimum brazed joints.  
This coil is 3/8 inch OD seamless alumi-  
num tubing glued to a continuous alumi-  
num fin. Coils are lab tested to withstand  
Burners — stainless steel. Multi-  
port inshot.  
Accessories  
(U.S. Domestic Models)  
Roof Curb — The roof curb shall  
be designed to mate with the unit  
and provide support and complete  
weather-tight installation when  
properly installed. Curb shall ship  
knocked down for field assembly,  
and include wood nailer strips.  
standards. The 4YCY4 heating/cooling unit 2,000 pounds of pressure per square inch.  
design is UL listed, specifically for outdoor  
applications using natural gas or propane.  
All units shall be designed for outdoor  
rooftop or ground level installation. Unit  
casing is constructed of heavy gauge,  
galvanized steel and painted with a  
weather-resistant powder paint.  
The outdoor coil provides low airflow  
resistance and efficient heat transfer. The  
coil is protected on all four sides by  
louvered panels.  
Indoor Air Fan — Direct-drive, forward-  
curved, centrifugal wheel in a Composite  
Vortica® Blower housing. Motor shall  
have thermal overload protection.  
Permanently lubricated motor bearings.  
Motor/blower assembly isolated from unit  
with rubber mounts.  
Modulating Economizer — This  
accessory shall be field installed  
and be composed of the following  
items: 0-100% fresh air damper,  
damper drive motor fixed dry bulb  
enthalpy control, and low voltage  
polarized plug for electrical  
Shipped for horizontal application,  
convertible to downflow.  
Casings  
All panels shall be heavy gauge steel,  
gasketed and insulated. Foil-faced  
insulation shall be in the heat exchanger  
Condenser Fan — Direct-drive, draw  
through propeller type. Weather-proofed  
connections. Solid state enthalpy or  
differential enthalpy control is  
optional. Economizer operations  
shall be controlled by the preset  
position of the enthalpy control. A  
barometic relief damper shall be  
standard with the economizer and  
provide a pressure operated  
section. Foil-faced insulation shall be in the permanent split capacitor fan motor shall  
evaporator section. Base pan shall be  
heavy gauge steel. WEATHERGUARD™  
exterior corrosion resistant screws shall be  
used for added resistance to rust and  
corrosion.  
have built-in thermal overload and  
permanently lubricated motor bearings.  
Low Ambient — Standard refrigerant  
system operation down to 55°F. Low  
ambient accessory required for operation  
to 0°F ambient condition.  
Controls  
Refrigeration cycle controls shall include  
condenser fan, evaporator fan and  
compressor contactors. Compressors shall  
be equipped with a combination internal  
winding thermostat/current overload.  
Internal high pressure relief shall also be  
provided.  
damper that shall be gravity closing  
and prohibit entrance of outside air  
on equipment “off” cycle.  
Gas-Fired Heating System — Models  
shall provide completely assembled, wired  
and piped gas fired heating systems within  
unit. Design certified by UL, specifically for  
outdoor application. Threaded gas  
connection on the unit.  
Manual Fresh Air Hood  
Manual outside air provides a fixed  
outside air quantity from 0 to 25  
percent. Includes hood and  
birdscreen.  
Refrigeration System  
Compressors —  
Electronic Ignition System — Main  
burner is lit each time thermostat calls for  
gas heat. Flame sensor proves flame and  
keeps the main burners on. Should a loss  
of flame occur, the main valve closes and  
the spark recurs within 0.8 second. When  
thermostat is satisfied, main burner is  
extinguished.  
Low Ambient Control  
Control allows cycling of  
compressor under low ambient  
cooling conditions. Required for  
cooling operation to 0°F.  
The Climatuff® compressor features  
internal over temperature and pressure  
protector, total dipped hermetic motor.  
Other features include: roto lock suction  
and discharge refrigeration connections,  
centrifugal oil pump, and low vibration and  
noise.  
Propane Gas  
Conversion Kit — For conversion  
from natural gas to LP gas.  
Forced Combustion Blower — Insures  
flame stability under varying wind  
conditions. Gives higher combustion  
efficiency and location flexibility.  
Evaporator Coil — Internally enhanced  
3/8-inch OD seamless copper tubing  
mechanically bonded to aluminum fins,  
factory pressure and leak tested at 250 to  
300 psig. All units have TXV to control  
refrigeration flow.
