DESCRIPTION

YORK Sunline Ultra units are high efficiency, convertible, single package air conditioners with a common cabinet and a common roof curb for the 3, 4 and 5 ton sizes. The units were designed for residential, light commercial and commercial applications. They can easily be installed on a roof curb, slab, roof jack or frame.

All units are self-contained and assembled on rigid full perimeter base rails with fork lift slots on three sides and holes for overhead rigging. Every unit is completely piped, wired, charged and tested at the factory to provide for a quick and easy field installation.

The units are available in cooling only, and cooling with gas heat. Electric heaters are available as field--installed acces sories.

Both bottom and side duct connections are available without having to swap panels. The installer simply removes the duct covers for the desired configuration. Economizers may be used on either bottom and side duct applications with no modifications required.

All models include a 5-year limited warranty on compressors, a 10-year limited warranty on gas-fired heat exchangers and a 1-year limited warranty on all replacement parts.

FEATURES

COMMON FOOTPRINT/COMMON CABINET - All model sizes and configurations share a common cabinet and a com mon roof curb. 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. He can even decide between gas or electric heat after the curb has been set.

HIGH EFFICIENCY - Units have a high cooling efficiency of as high as 13.2 SEER and gas / electric models have a mini mum AFUE of 80.3%. All efficiencies exceed legislated minimum levels and provide low operating costs.

CONVERTIBLE AIRFLOW DESIGN - Both the side and bottom duct openings are covered when they leave the factory. If a side supply / side return is desired, you simply remove the two side duct covers from the outside of the unit and discard them. If a bottom supply / bottom return is desired, you simply remove the two knockout panels from the base of the unit and discard them. No panel cutting or swapping is required! Con vertible airflow design allows maximum field flexibility and minimum inventory.

FACTORY--INSTALLED OPTIONS - Economizers can be installed at the factory. The economizers are shipped installed and wired. Only the rain hood needs to be field assembled and installed. Field labor dollars can be saved by having the components arrive already installed.

FIELD--INSTALLED ACCESSORIES - Accessories were designed for quick and easy installation. The motorized

damper and economizers simply slide in, and electrical con nections are made by modular plugs. Electric heaters mount easily, and knockouts are provided in the internal partitions to connect the elements to the control box single point kit.

The motorized air damper includes a slid-in/plug-in damper assembly with a rainhood and filters. The outdoor air damp ers open when the indoor fan motor is energized. The damper is capable of providing 0% through 100% of outdoor return air opening.

The manual outdoor damper provides 0% through 35% or 0% through 100% of return air opening (field adjustable). Designed for duct mounted side or bottom supply/return applications. Includes rain hood assembly and filter.

The 14" high roof curb is shipped knocked down. An insulated deck is not required because the bottom of the unit is insulated.

Low ambient controls are available to provide stable unit operation at outdoor temperatures down to 0F.

Propane, high altitude and low NOx kits are also available to cover all gas heating applications.

WIDE RANGE OF INDOOR AIRFLOWS - All models operate over a wide range of design conditions with the use of belt-drive blowers. The variable pitch pulley on the blower motor can be adjusted to obtain the desired supply air CFM.

FULL PERIMETER BASE RAILS - The permanently attached base rails provide a solid foundation for the entire unit and

protect the unit during shipment. The rails provide fork lift access from 3 sides, and rigging holes are also provided so that an overhead crane can be used to place the units on a roof.

SYSTEM PROTECTION - Internal overload protection is standard on all compressors. Every unit has a liquid line filter-

-drier, high and low pressure/loss of charge switches and a suction line freezestat to protect all system components. All units will provide cooling at ambient temperatures down to 45F.

UTILITY CONNECTIONS MADE EASY - Gas and electric utility knockouts are provided in the unit base as well as the side of the unit. A clearly identified location is provided to mount a field supplied electrical disconnect switch. Utility connections can be made quickly and with a minimum

amount of field labor.

SIMPLE CONTROL CIRCUIT - A low voltage printed circuit board contains a compressor lockout indicator light and a low voltage terminal strip. An additional set of pin connectors is also provided to simplify the field interface of external con trols. Mate-n-lock plug connectors are used where line and low voltage wires pass through internal bulkheads. This allows for easier troubleshooting and component replacement. The electrical control box is not located in the compressor compartment so the access cover can be removed for

Unitary Products Group 3

troubleshooting without affecting the normal system operating pressures.

AIR FILTERS - Units are shipped with 1" throwaway filters. The unit filter racks can accommodate 1" or 2" filters without any modifications

FACTORY-INSTALLED OPTION

ECONOMIZERS: Units equipped with a factory-installed economizer option have dampers that are positioned by a spring return, fully modulating damper actuator and are capa ble of introducing up to 100% outdoor air. As the outdoor air intake dampers open, the return air dampers close. The changeover from mechanical refrigeration to economizer operation is determined by a single input electronic enthalpy control or by a dual input electronic enthalpy control. Simulta neous compressor and economizer operation is also possible.

The single enthalpy system contains a sensor that monitors the outdoor air which automatically operates the damper actuator allowing the dampers to open or close.

The dual enthalpy system contains a second sensor that monitors both the temperature and the humidity of the return air in addition to the outdoor air sensor described for a single enthalpy system. The logic module compares the inputs from both sensors and switches to economizer operation when ever the outdoor air is cooler than the return air for maximum efficiency of the economizer system.

The economizer is completely wired and installed at the factory. Only the outdoor air hood, including its filters, need be assembled and installed in the field.

FIELD-INSTALLED ACCESSORIES

SINGLE INPUT ELECTRONIC ENTHALPY ECONOMIZER Includes a slide-in / plug-in damper assembly with fully modu lating spring return motor actuator capable of introducing up to 100% outdoor air, one outdoor air electronic enthalpy sen sor and a rain hood with filters. The rain hood is painted to match the basic unit and must be field-assembled before installation. Economizer dampers are 2% low leakage type.

DUAL INPUT ELECTRONIC ENTHALPY ECONOMIZER Includes the same damper system and rain hood with filters as described for a single enthalpy economizer except this accessory contains two enthalpy sensors. It uses a differen tial enthalpy control that compares the outdoor air versus the return air. The logic module then optimizes the economizer operation for additional savings over the single input economizer.

MOTORIZED AIR DAMPER - Includes a slid-in/plug-in damper assembly with a rainhood and filters. The outdoor air dampers open when the indoor fan motor is energized. The damper is capable of providing 0% through 100% of outdoor return air opening.

MANUAL OUTDOOR DAMPER - Provides 0% through 35% or 0% through 100% of return air opening (field adjustable). Designed for duct mounted side or bottom supply/return applications. Includes rain hood assembly and filter.

ELECTRIC HEATERS - Include nickel chromium elements, a terminal block, fuses (where required by UL), all the neces sary connectors and hardware. All heaters utilize single point power supply hookup. Capacities from 5 KW thru 30 KW heating are available.

FUSE BLOCK KITS - These kits have a fuse box with a fuse

block and fuses. They're available for all 460-3-60 volt heat

ers and 208/230-3-60 volt heaters 7 KW and smaller.

OUTDOOR THERMOSTAT - A 24-volt thermostat providing two stages of control for units equipped with electric heat

accessories.

ROOF CURB - This 14" high full perimeter roof curb is shipped knocked down for field assembly and contains duct supports that can easily be

shifted for the desired unit duct arrangement. No insulated deck is required because the unit underside is insulated.

START ASSIST KIT - Provides increased starting torque for single phase units in areas with low voltage conditions. It con tains a 12.5 OHM PTCR temperature resistor with a support clip and hardware for mounting.

LOW AMBIENT KIT - A head pressure controller maintains stable system operation by reducing the speed of the con denser fan motor when the outdoor temperature is between 45 and 0F. Condenser fan motors with ball bearings and heavier windings are also available for these low ambient applications.

ANTI-RECYCLE TIMER - A timer to prevent the unit compressor from short cycling. It assures a 5-minute off-time between compressor cycles.

PROPANE CONVERSION KIT - Converts a gas-fired heater

from natural gas to propane. It contains main burner orifices,

a pilot orifice and a regulator spring.

LOW NOx KIT (natural gas furnaces only) - Contains five stainless steel expanded metal sheets for mounting into the heat exchanger tubes to meet the California low nitrous oxide emission requirements.

HIGH ALTITUDE CONVERSION (NATURAL AND PROPANE) - Provides orifices for proper furnace operation at altitudes up to 6000 feet. For propane applications, the propane conversion kit will also be required.

GAS PIPING - This kit contains 1/2" pipe nipples, fittings and gas cock (including panel access gaskets) required for bot tom gas supply connection with external shut-off.

OUTDOOR COIL GUARD - Consists of grille-type sections for installation over the outdoor coil to protect it from damage.
