The cooling coil shall have a minimum of _____ sq. ft.

(sq. m) face area, _____ rows deep. The coil shall be

controlled by a modulating control valve. The chilled water coil shall be designed for closed-loop applica- tions using properly maintained water. It shall be configured as an (A) (V) frame and be constructed of copper tubes and aluminum fins and have a maxi- mum face velocity of _____ ft. per minute (m/s) at

_____ CFM (CMH). The water circuit shall be

designed to distribute water into the entire coil face area. The coil shall be supplied with _____ °F (°C)

entering water temperature, with a _____ °F (°C)

temperature rise. The coil shall be supplied with

_____ GPM (m/s) of chilled water and the pressure

drop shall not exceed _____ PSI (kPa). The coil

assembly shall be mounted in a stainless steel con- densate drain pan.

3-Way Chilled Water Valve (Standard)

The water circuit shall include a 3-way modulating valve. The microprocessor control shall position the valve in response to room conditions. Cooling capac- ity will be controlled by bypassing chilled water around the coil.

2-Way Chilled Water Valve (Optional)

The water circuit shall include a 2-way modulating valve. The microprocessor control shall position the valve in response to room conditions. The minimum close-off pressure of the valve/actuator assembly shall be _____ PSI (kPa).

Design Pressure

The chilled water circuit shall be designed for a pres- sure of [(150 PSI (1034 kPa)) (400 PSI (2758 kPa))].

Flow Switch (Optional)

The flow switch shall activate the alarm system should the chilled water supply be interrupted. The switch shall be factory mounted and wired.
