All coils are tested with air under water. 4. All coils shall have manual air vent to allow purging of air from coils. D. Controls and Safeties: Unit shall be furnished with optional factory installed controls: manual -speed, 4-position fan switch; or thermostat-ready with -speed, 4-position fan switch; or unit mounted thermostat. The fan motor(s) shall be equipped with integral automatic temperature reset for motor protection. E. Operating Characteristics: 1. A unit with single hydronic coil installed in a -pipe system shall be capable of providing heating or cooling as determined by the operating mode of the central water supply system, and controlled as determined by valve (factory or field-provided and installed) and controls (factory or field-provided and installed).. A unit with two hydronic coils installed in a 4-pipe system shall be capable of providing heating and cooling, controlled as determined by valves (factory or field-provided and installed) and controls (factory or field-provided and installed). F. Electrical Requirements: The unit power supply shall be single phase, 6 Hz. The standard unit is 1V, but 8/4V and 77V options are available. G. Motor(s): Fan motors shall be -speed; permanent split capacitor type, with factory-sealed permanently lubricated sleeve or ball type bearings. H. Outside Air Damper 1. Optional motorized OA damper shall be two-position and include two-position 4V actuator. Damper actuator shall be factory wired to open when fan is energized and to spring return closed when fan is de-energized.. Optional manual OA damper shall have factory mounted locking quadrant type manual damper operator. I. Valve Packages Optional factory provided valve packages shall have configuration as indicated in the nomenclature, complete with all fittings including ball valves, ball valve with memory stop, circuit setter, unions, PT ports, and - or -way two position control valve, as applicable. Heating coil valve package control valves shall be piped normally open to the coil. Cooling coil valve packages shall have option to be piped normally open or normally closed to the coil. Control valves shall spring return to normal position upon loss of power. Control valves shall have Cv ratings as follows: -way, Cv =.5; -way, Cv = 4.. Customer is responsible for protecting the unit from freezing conditions. Page 6/15/1
