All fans shall be statically and dynamically balanced and tested in factory. Supply fans shall be test run in unit as part of unit test. Unit shall reach rated rpm before fan shaft passes through first critical speed. Fan shafts shall be mounted on two grease lubricated ball bearings designed for 200,000 hours average life. Optional extended grease lines shall allow greasing of bearings from unit filter section. Fan motor and fan assembly shall be mounted on common base to allow consistent belt tension with no relative motion between fan and motor shafts. Entire assemblies shall be completely isolated from unit and

fan board by two-inch deflection spring isolators. All supply fan motors meet the U.S. Energy Policy Act of 1992 (EPACT).

Controls

Unit shall be completely factory wired with necessary control and contactor pressure lugs or terminal block for power wiring. Units shall provide an internal location for a non-fused disconnect with external handle for safety. Unit mounted microprocessor controls shall provide anti-short cycle timing for compressors to provide a high level of machine protection.

Unit Controller

DDC microprocessor controls shall be provided to control all unit functions.The control system shall be suitable to control CV or VAV applications.The controls shall be factory-installed and mounted in the main control panel. All factory-installed controls shall be fully commissioned (run tested) at the factory. The unit shall have a Human Interface Panel with a 16 key keypad, a 2 line X 40 character clear English display as standard to provide the operator with full adjustment and display of control data functions.The unit controls shall be used as a stand-alone controller, or as part of a building management system involving multiple units.

1

The unit shall be equipped with a complete microprocessor control system.This system shall consist of temperature and pressure (thermistor and transducer) sensors, printed circuit boards (modules), and a unit mounted Human Interface Panel. Modules (boards) shall be individually replaceable for ease of service. All microprocessors, boards and sensors shall be factory mounted, wired and tested.

The microprocessor boards shall be stand-alone DDC controls not dependent on communications with an on-site PC or a Building Management Network.The microprocessors shall be equipped with on-board diagnostics, indicating that all hardware, software and interconnecting wiring are in proper operating condition.

The modules (boards) shall be protected to prevent RFI and voltage transients from affecting the board’s circuits. All field wiring shall be terminated at separate, clearly marked terminal strip.

Direct field wiring to the I/O boards is not acceptable.

The microprocessor’s memory shall be non-volatile EEPROM type requiring no battery or capacitive backup, while maintaining all data.

2

Zone sensors shall be available in several combinations with selectable features depending on sensor.

3

The Human Interface Panel’s keypad display character format shall be 40 characters x 2 lines.The character font shall be 5 x 7 dot matrix plus cursor.The display shall be Supertwist Liquid Crystal Display (LCD) with blue characters on a gray/green background which provides high visibility and ease of interface.The display format shall be in clear English. Two or three digit coded displays are not acceptable.

4

The keypad shall be equipped with

16 individual touch-sensitive membrane key switches.The switches shall be divided into four separate sections and be password protected from change by unauthorized personnel.The six main menus shall be STATUS, SETPOINTS, DIAGNOSTICS,

SETUP, CONFIGURATION and SERVICE MODE.

Filters

General

Filter options shall mount integral within unit and be accessible by hinged access panels.

No Filters (two inch throwaway filter rack only) option

Shall provide a complete set of two-inch thick filter racks, without the filter media to accommodate applications which require field supplied filters.

No filters (bag/cartridge with prefilter filter rack option)

Shall provide a long-lasting galvanized steel frame without the filter media to accommodate applications which require field supplied filters.
