YORK

Predator

MagnaDry™ units are convertible single

packages with a common footprint cabinet and common roof

curb for all 7-1/2 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 can be easily installed on a roof

curb, slab, or frame.

All Predator

MagnaDry™ units are self-contained and

assembled on rigid full perimeter base rails allowing for 3-way

forklift access and overhead rigging. Every unit is completely

charged, wired, piped, and tested at the factory to provide a

quick and easy field installation.

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

MagnaDry™ units are available in the following

configurations: cooling only, cooling with electric heat, and

cooling with gas heat. Electric heaters are available as fac-

tory-installed options or field-installed accessories.

The Predator

MagnaDry™ provides energy-savings, effi-

cient removal of moisture through a balanced coil design.

Because the unit doesn’t increase sensible cooling, it allows

temperatures to be maintained within the comfort zone.

Unlike competitive systems, you’re not subjected to over

cooling. You save through more efficient matching of dehu-

midification and cooling needs. This makes the MagnaDry™

perfect for applications that need to remove large amounts of

moisture or maintain low humidity levels.

Convertible airflow design allows maximum field flexibility and minimum inventory. • • System Protection - Suction line freezestats are supplied on all units to protect against loss of charge and coil frosting when the economizer operates at low outdoor air temperatures while the compressors are running.

246721-YTG-C-0606 • • • Downflow Economizer - (With barometric relief) The economizer is provided with a single enthalpy input. The economizer is 2% low leakage type, and is shipped installed and wired. The installer needs only to assemble and mount the outdoor air hood (Provided). The economizer has spring return, fully modulating damper actuators and is capable of introducing up to 100% outdoor air. As the outdoor air intake dampers open, the return air dampers close.

246721-YTG-C-0606 When the room thermostat calls for second stage cooling, the RCB senses a signal through "Y1" & "Y2" and engages circuit #1 and circuit #2 in cooling mode. Indoor blower operation is initiated upon a call for first stage cooling, second stage cooling or dehumidification. Anytime there is a call for 2 stages of cooling, the unit will not operate in the reheat mode, even if there is a call for dehumidification at "HUM".

246721-YTG-C-0606 GUIDE SPECIFICATIONS PREDATOR® MagnaDRY™ DR 090, 120 & 150 GENERAL Units shall be manufactured by York International Unitary Products Group in an ISO 9001 certified facility. YORK® Predator® MagnaDRY™ units are convertible single packages with a common footprint cabinet and common roof curb for all 7-1/2 through 12-1/2 ton models. All units have two compressors with independent refrigeration circuits to provide 2 stages of cooling.
PAGE 63
246721-YTG-C-0606 Refrigerant Circuit and Refrigerant Safety Components shall include: air entering temperature of 40 ºF. Burners shall be of the inshot type, constructed of aluminum-coated steel. All gas piping shall enter the unit cabinet at a single location, through either the side or bottom, without any field modifications. An integrated control board shall provide timed control of evaporator fan functioning and burner ignition.
PAGE 64
2. outdoor and return air damper assembly to prevent the supply air temperature from dropping below 55 ºF. Changeover from compressor to economizer operation shall be provided by an integral electronic enthalpy control that feeds input into the basic module. The outdoor intake opening shall be covered with a rain hood that matches the exterior of the unit. Water eliminator/filters shall be provided. Simultaneous economizer/compressor operation is also possible. Dampers shall fully close on power loss.
