PKGP -PRC0 03-EN 5 Easy to Install, Service and Maintain Because today’ s owner s are very cost- conscious when it comes to service and maintenance, the T rane Precedent was designed with direct input from service contractor s.
6 PKGP -PRC0 03-EN F eatures and Benef its Black Epoxy Pre-Coated Coils The pre-coated coils are an economical option for protection in mildly corrosive environments.
PKGP -PRC0 03-EN 7 High Pressure Cutout This factory-installed option is offered for units that do not have High Pressure Cutout as standard. All 3-phase units with scroll compressors include High Pressure cutout as standard.
8 PKGP -PRC0 03-EN Unit Cabinet The compact cabinet with rounded corners takes up less room and is less costly to ship. The beveled and ribbed top is not only aesthetically pleasing, it is designed to prevent water from pooling.
PKGP -PRC0 03-EN 9 Easy to Install Convertible Units – The units ship in a downflow configuration. They can be easily converted to horizontal by simply moving two panels. – Units come complete with horizontal duct flanges so the contractor doesn’t have to field fabricate them.

PKGP -PRC0 03-EN 53 Mec hanical Specif ications General The units shall be conver tible airflow. The operating range shall be between 1 15°F and 0°F in cooling as standard from the factory for units with microprocessor controls. Operating range for units with electromec hanical controls shall be between 1 15°F and 40°F .
54 PKGP -PRC0 03-EN Mec hanical Specif ications F actory Installed Options Black Epoxy Pre-Coated Coils The blac k epoxy coils have a thermoset vinyl coating that is bonded to the aluminum fin stoc k prior to the fin- stamping process. The pre-coated coils are an economical option for protection in mildly corrosive environments.
PKGP -PRC0 03-EN 55 Mec hanical Specif ications Frostat This option is to be utilized as a safety device. The Frostat opens when temperatures on the evaporator coil fall below 1 0°F . The temperature will need to rise to 50°F before closing. This option should be utilized in low airflow or high outside air applications.
