Mechanical Specification Options General 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 R-22. Units shall be UL listed and carry a UL label. 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 115°F and 55°F in cooling as manufactured. Cooling performance shall be rated in accordance with ARI standards. Unit Casing All components shall be mounted in a weather-resistant steel cabinet with an enamel finish. Access panels shall be provided for unit controls and indoor coil and fans. Indoor air section compartment shall be completely insulated with fireproof, permanent, odorless glass fiber material. Knockouts shall be provided for utility and control connections. Drain connections shall be provided to accommodate indoor water runoff. Compressor The compressor shall be a hermetically sealed, high efficiency Climatuff ® compressor. Internal overcurrent and over temperature protection, internal pressure relief shall be standard. Crankcase heaters shall be standard on all three phase models. Refrigeration System All units shall have capillary tube refrigerant control. Service pressure tap ports, and a refrigerant line filter dryer shall be standard. Indoor and Outdoor Coils Coils shall be internally finned or smooth bore 3/8" copper tubes mechanically bonded to configured aluminum plate fin as standard. Evaporator coil leak and pressure tested to 200 psig; condenser coil tested to 450 psig. Indoor Fan The indoor fan shall be a forward curved, centrifugal-type fan with a multiple-speed, direct drive motor. Motor is permanently lubricated and shall have built-in overload protection. 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. 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. Manual Outside Air Dampers — Rain hood and screen shall be field installed. Suitable for up to 25% outside air. Anti-Short Cycle Timer — Timed off device that ensures a minimum of five minutes off between compressor cycles. 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 Setback Thermostat — Programmable electronic thermostat shall provide heating setback and cooling setup with 7-day, programming capability. 1H/1C or 2H/2C models available. 26 IPB-99-7-EN-10-6-99
