American Standard - Gold Series, 3 Ton, 15 SEER, R410A Convertible Packaged Cooling, 208-230V, 1 Phase

 Gold Series, 15 SEER, R410A Convertible Cooling Package Unit

The units shall be horizontal airflow as shipped and convertible to Downflow. All units shall be factory assembled, piped, internally wired and fully charged with R410A. All units shall be factory run tested to check cooling operation, fan and blower rotation and control sequence. Units shall be designed to operate at ambient temperatures between 55°F and 115°F in cooling as manufactured. Cooling performance shall berated in accordance with A.R.H.I. standards.

Unit Casing
All panels shall be heavy gauge steel, gasketed and insulated. Foil-faced fiber insulation shall be in the heater section. Foil-faced fiber insulation shall be in the evaporator section. Base pan shall be heavy gauge steel. WEATHERGUARD™ exterior corrosion resistant screws shall be used for added resistance to rust and corrosion.

Compressor
The compressor shall be a hermetically sealed, high efficiency Duration™ compressor. Internal overcurrent and over temperature protection, internal pressure relief shall be standard. Other features include, centrifugal oil pump and low vibration and noise.

Refrigeration System
All units shall have refrigerant control. Service pressure tap ports, and a refrigerant line filter shall be standard.

Evaporator Coil
Internally enhanced 3/8" OD seamless copper tubing mechanically bonded to aluminum fins, factory pressure and leak tested at 250 to 300 psig. All units have a TXV to control refrigerant flow.

Condenser Coil
The Spine Fin™ condenser coil shall be continuously wrapped, corrosion resistant all aluminum with minimum brazed joints. This coil is 3/8" O.D. seamless aluminum tubing glued to a continuous aluminum fin. Coils are lab tested to withstand 2,000 pounds of pressure per square inch. 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
Constant Torque, forward-curved, centrifugal wheel in a Composite Vortica ® Blower housing. Motor shall have thermal overload protection and permanently lubricated motor bearings. Motor/blower assembly isolated from unit with rubber mounts.

Outdoor Fan
One direct-drive, statically and dynamically balanced propeller fan shall be used in a draw-through vertical discharge configuration. Permanently lubricated weather proof motor shall have built-in thermal overload protection.

System Controls
System controls include condenser fan, evaporator fan and compressor contactors.

Accessories Roof Curb
The roof curb shall be designed to mate with the unit and provide support and complete weathertight installation when properly installed. Adhesive back polyurethane sealing strips shall be provided to ensure an airtight seal between supply and return openings of the curb and unit. The roof curb design allows field fabricated ductwork to be connected directly to the curb. Curb ships knocked down for field assembly, and includes factory installed wood nailer strips.

Electric Heaters
Each heater assembly shall include power supply fusing if over 48 amps, automatic resetting limit switches and heat limiters for thermal protection. Heaters shall be provided with polarized plugs for quick connection to unit low voltage wiring. Electric heat modules shall be UL listed.

Single Source Power Entry
This accessory when used with electric heat accessory shall allow single source power connection to unit and heater combination. Single source power entry kits shall have specific matching heater(s). Kit shall include high voltage terminal blocks, fuse blocks and fuses, cutto-length interconnecting wiring, and junction box (if required) to provide power sources with fuse protection as required for both the unit and accessory heater. Kit components shall install within the heater cabinet in the heater access section. Single source branch power circuit shall be protected and wired in accordance with local codes.

Fully 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 pigtails for electrical connections. Solid state enthalpy or differential enthalpy control is optional. Economizer operations shall be controlled by the preset position of the enthalpy control. A barometric relief damper shall be standard with the economizer and provide a pressure operated damper that shall be gravity closing and prohibit entrance of outside air on equipment "off" cycle. Economizer requires BAYRLAY004A relay kit to interface the economizer to the heat pump.

Manual Outside Air Dampers
Rain hood and screen shall be field installed. Suitable for up to 25% outside air.

Control Options
Standard Indoor Thermostats
Two stage heating/cooling or one stage heating/cooling thermostats shall be available in either manual or automatic changeover.

Programmable Electronic Night Setting Thermostat
Programmable electronic thermostat shall provide heating setback and cooling setup with 7–day programming capability. 1H/1C or 2H/2C models available.
