YORK Predator units are convertible single packages with a common footprint cabinet and common roof curb for all 6-1/2. through 12-1/2 ton models. All units have two compressors with independent refrigeration circuits to provide 2 stages of cooling. The units were designed for light commercial applications and HIGH EFFICIENCY can be easily installed on a roof curb, slab, or frame. SINGLE PACKAGE AIR CONDITIONERS AND All Predator units are self-contained and assembled on rigid full perimeter base rails allowing for 3-way forklift access and SINGLE PACKAGE GAS/ELECTRIC UNITS overhead rigging. Every unit is completely charged, wired, piped, and tested at the factory to provide a quick and easy field DH 078, 090, 102, 120, 150 installation.
2 6-1/2, 7-1/2, 8-1/2, 10, 12-1/2 NOMINAL TONS All units are convertible between side and down airflow. Inde- pendent economizer designs are used on side and down dis- charge applications, as well as all tonnage sizes. Predator units are available in the following configurations: cooling only, cooling with electric heat, and cooling with gas heat. Electric heaters are available only as field-installed acces- sories. Tested in accordance with: FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE. 036-21059-002 REV B (0201).
