charging valve. Protective devices for low pressure, high pressure and
motor temperature shall be provided. The compressors shall be mounted
on rubber-in-shear isolators for vibration insolation. CONDENSER: One
condenser shall be provided for each Compressor. The condensers shall
be shell-and-tube design with removal heads and mechanically cleanable
tubes. Condenser tubes shall be nominal inch O.D. copper. Condenser
waterside working Pressure shall be 400 psig. Unit will allow condenser
water piping to be brought to the condensers from the right side of the
unit. All water piping including economizer valve package shall be
manifolded into a single inlet and outlet and extended to the exterior
of the unit. EVAPORATOR: The evaporator coil shall be seamless copper

and external equalizer, and high-pressure relief valves with a -inch
SAE flare connection. The circuits shall be tested, dehydrated and then
charged with oil and Refrigerant-22. SUPPLY FAN, DRIVE AND MOTOR: The
supply fan shall be dual, forward curved medium pressure fans secured
to a solid steel shaft with grease-lubricated bearings designed for
200,000 hours. The drive components shall include fixed-pitch sheaves
and multiple V-belts sized for 150 percent of nominal motor horsepower.
The supply fan motor shall have a standard T-frame. The entire fan
assembly, including drive components, shall be mounted on a common
base. The fan base shall be isolated inside the unit. The entire
assembly shall be statically and dynamically balanced at the factor to
a maximum tolerance of 3 mils peak to peak. FAN MODULATION: The
variable volume unit shall operate at design airflow based on fan and
motor drive selections. Fan and motor sheaves will be selected for a
rpm to develop airflow at design static pressure. INLET GUIDE VANES:
Airflow modulation shall be by inlet guide vanes. The inlet vanes,
complete with electric actuator, linkage and controller shall be
factory-installed and adjusted. The static pressure setpoint shall be
adjustable. A duct static pressure sensing probe shall be proved for
field-installation. FILTERS: Two-inch medium velocity throwaway filters
shall be provided for unit operation. UNIT CONTROLS: Unit Control
Module- The microprocessor controller shall control all unit functions,
including the economizer, mechanical refrigeration and fan modulation
and monitor diagnostics. All controls shall be factory installed and
adjusted. The controller shall include a switch to place the unit in
Auto Remote, Auto Local or Stop/Reset mode; an indicator display to
show unit operating status, diagnostics and setpoints; and adjustable

minimum position, supply air temperature control band and supply air
pressure high static limit. The three-position switch and indicator
display shall be accessible without opening any unit panels. ENTERING
AIR TEMPERATURE PROTECTION: A single-point sensor is used to detect
entering air temperature to the unit. If entering air temperature to
the unit exceeds 135 F or falls below 37 F, the unit will shut down and
display a diagnostic code. Manual reset is required when the entering
air temperature rises above 135 F. RATINGS: Design cooling capacity
