Features and Benefits

Standard Features

•Operating Efficiency - All gas units provide a minimum AFUE of 80% and SEERS of 13.0. All efficiencies exceed legislated minimum levels.

•On Site Flexibility - All model sizes share a common, compact design cabinet in a single footprint. The installer has the flexibility of setting one curb and placing the proper tonnage unit on that curb after the internal load has been determined. Field convertible duct connections from side shot to down shot allows the installer to have greater flexibility with less inventory.

•Lower Installation Cost - Installation time and costs are reduced by easy power and control wiring connections. The small base dimension means less space is required on the ground or roof, plus, the installer can fit this unit between the wheel wells of full size pick-up truck.

All units are completely wired, charged with R-410A and tested prior to shipment. Unique test stations using a new state of the art computerized process system are used to insure product quality. Refrigerant charge and component part numbers are verified via computers at assembly. Vital run test statistics such as system pressure, motor currents, air velocity and temperature, unit vibration, and gas system safeties are monitored and recorded by the system to insure unit performance.

Equal size, side supply and return duct connections allows easy hook-up of ducts to match low crawl spaces without transition pieces.

•Utility Connections Made Easy - Gas and electric utility knockouts are provided through the bottom as well as the side of the unit. Utility connections can be made quickly and with a minimum amount of field labor. A field supplied and field installed electrical disconnect switch must be installed.

•Convertible Airflow Design - The bottom duct openings are covered when they leave the factory ready to be used

for a side supply/side return application. If a bottom supply/bottom return application is desired, you simply remove the two panels from the bottom of the unit and place them in the side supply/side return duct openings. No panel cutting is required and no accessory panel is necessary. Convertible airflow design allows maximum field flexibility and minimum inventory.

•Condensate Pan - A non-corrosive, long-lasting, watertight pan is positioned below the evaporator coil to collect and drain all condensate. Less collection of stagnate condensate will build-up. The condensate pan conforms to ASHRAE 62-89 standards (Ventilation for Acceptable Indoor Air Quality).

•Condensate Drain - The 3/4 inch NPTF connection is rigidly mounted to assure proper fit and leak tight seal.

•Durable Finish - The cabinet is made of pre-painted steel. The pre-treated galvanized steel provides a better paint to steel bond, which resists corrosion and rust creep. Special primer formulas and matted-textured finish insure less fading when exposed to sunlight.

•Full Perimeter Base Rails - The easily removable base rails provide a solid foundation for the entire unit and protects the unit during shipment. The rails provide fork lift access from all sides, and rigging holes are also provided so that an overhead crane can be used to place the units on a roof. On applications where the unit is placed on a pad, the base will keep the unit off the pad to deter corrosion. On applications where height is limited, the inch high base rails may be removed on location.

•More Attractive Appearance - A single piece Water Shed top cover containing a top discharge condenser fan arrangement requires less square footage on installation and provides a wider variety of installations. The one piece design adds greater water integrity. Rounded corners with water drip edges add to the attractive appearance. The cabinet panels have a non-fibrous insulation that will not release insulation fibers into conditioned area.

•Top Discharge - The top discharge condenser fan does not disrupt neighboring areas or dry-out vegetation surrounding the unit. The warm air from the top mounted fan is blown up away from the structure and any landscaping. This allows compact location on multi-unit applications.

•Condenser Coil Grille - All models utilize a decorative “Wire Form” coil guard to provide impact protection against large objects.

•Low Operating Sound Level - The upward air flow carries the normal operating noise up and away from the living area. The rigid top panel effectively isolates any motor sound. Isolator mounted compressor and the rippled fins of the condenser coil muffle the normal fan motor and compressor operating sounds. The unique formed base pan also aids in sound alterations with it's Super-Structure design. This design strategically places embossments in the pan for optimum strength and rigidity.

•Fan System - All models operate over a wide range of design conditions with an electrically commutated fan motor. These units easily match all types of applications and provide greater on site flexibility to match comfort requirement. The cooling speed is factory set and can be field adjusted to a second speed. The heating speed is factory set to maintain mid point rise at the units heating input, but can be field adjusted. This allows maximum comfort conditions.

•Simple Control Circuit - A low voltage printed circuit board contains a diagnostic indicator light and a low voltage terminal strip. An additional set of pin connectors is also provided to simplify the field interface of external controls. Mate-n-lock plug connectors are used. The electrical control box is not located in the compressor compartment. The controls are mounted on a Control-Tilt control panel to allow the access cover to be removed for trouble shooting and maintenance without affecting the normal system operating pressures. All wiring internal to the unit is color/number coded.

•Protected Compressor - The compressor is internally protected against high pressure and temperature. This is accomplished by the simultaneous operation of high pressure relief valve and a temperature sensor which protect the compressor if undesirable operating conditions occur.

•Pressure Switches - High pressure and low pressure/ loss of charge switches standard in all units. When abnormal conditions are sensed through the pressure switches, the unit will lock out preventing any further operation until reset or problem is corrected.

•Exclusive Coil Design - Grooved copper tubes and enhanced aluminum fin construction improves heat transfer for maximum efficiency and durability or MicroChannel aluminum tube, aluminum fin for long lasting durability and efficient operation.

•Heat Exchangers - Are corrosion-resistant, aluminizedsteel tubular construction to provide long-life, trouble-free operation. The unique blow-through design also assures that condensate does not collect in humid areas when in

the cooling cycle. This adds to longer heat exchanger life and higher long term efficiencies.

•Post Purge Induced Draft Combustion - Exhausts combustion products from the heat exchanger upon completion of the heating cycle to prolong the heat exchanger life.

•Self Diagnostic Fan Control Module - Due to this self diagnostic control, less on site time is required to trouble shoot these units.

•Spark To Pilot Ignition - Provides faster heat delivery. This ignition is highly reliable, durable and eliminates nuisance lockouts.

•Multi Port In-shot Burners - No field adjustment is required to mix the air and gas. These burners are constructed of high-grade corrosion-resistant, aluminizedsteel.

•Low Maintenance - Long life, permanently lubricated condenser and evaporator fan motor bearings need no annual maintenance adding greater reliability to the unit. Blower assembly can be easily cleaned by the unique SlipTrack slide-out blower assembly.

•Secured Service Access Ports - Protected, externally mounted, re-usable service access ports are provided on both the high and low lines for ease of evacuating and charging the system. No final field mounting required.

•Easy Service Access - A large, single panel covers the electrical and gas controls makes servicing easy. The blower compartment has an additional large panel with a built-in handle tab. Removing this panel will allow the blower assembly to slide-out for easy removal for maintenance and ease of trouble shooting.

•Replacement Parts - The installer requires no special training to replace any of the components of these units and does not need to maintain an inventory of unique parts.

•System Integration - Each unit has the internal ability to integrate an electronic air cleaner or humidifier to work in conjunction with the base unit.
