the optional convenience outlet. All incoming power is connected in one location, reducing the cost of field-supplied and installed power wiring.
•Factory-mounted and wired controls – All con- trol points within the unit are factory-installed, wired and tested. The OptiLogicTM controls can commu- nicate with BACNet IP.
•Non-fused disconnect – A factory-installed non- fused disconnect switch simplifies unit installation and serviceability by reducing installed labor costs. The disconnect switch is interlocked with the power cabinet ensuring that all power to the unit has been disconnected before servicing.
Design Flexibility
•Low Ambient Operation – Head-pressure control is accomplished via a VFD motor controller rather than an inefficient and noisy condenser fan damper. By varying the speed of the condenser fan, better control and quieter operation is obtained during the colder months. Low ambient controls are available
on all systems offering higher rooftop cooling ca- pacity than competitive units.
•Hot Gas Bypass – Optional on constant volume units, hot gas bypass reduces the cycling of compressors which helps prolong the life of the equipment.
•Supply Air Openings – Side supply connections are available on select configurations, offering more flexibility for duct layout and improving sound trans- mission characteristics.
•Compressor Sound Blankets – For applications in sound-sensitive areas, compressor sound blan- kets are available to reduce sound emitted from the rooftop unit.
•Fan Spring Isolators – One-inch spring isolation is used to prevent vibration transmission from the rooftop unit’s supply fan to the building. Two-inch spring isolation is also available.
•Harsh Environments – A variety of coil coating and materials are available as well as hail guards to pro- tect coils from weather damage. Seismic and hurri- cane duty curbs and fan restraints are available.
