With no-strip screw collars, handled access panels, and more we ve made your unit easy to install, easy to maintain and easy to use. Easy to install: All WeatherMasterR units are field-convertible to horizontal air flow, which makes it easy to adjust to unexpected job-site complications. Lighter units make easy replacement. Most of Carrier s ton rooftops fit on existing Carrier curbs dating back to Also, our large control box gives you room to work and room to mount Carrier accessory controls. Easy to maintain: Easy access handles by Carrier provide quick and easy access to all normally serviced components. Our no-strip screw system has superior holding power and guides screws into position while preventing the screw from stripping the unit s metal. Take accurate pressure readings by reading condenser pressure with panels on. Simply remove the black, composite plug, route your gauge line(s) through the hole, and connect them to the refrigeration service valve(s). Now, you can take refrigeration system pressure readings without affecting the condenser airflow. Easy to use: The newly designed, central terminal board by Carrier puts all your connections and troubleshooting points in one convenient place, standard. Most low voltage connections are made to the same board and make it easy to find what you re looking for and easy to access it. Carrier rooftops have high and low pressure switches, a filter drier, and 2 (51mm) filters standard. 2

6 FACTORY OPTIONS AND/OR ACCESSORIES Convenience Outlet (powered or un -powered) Economizers save money. They bring in fresh, outside air for ventilation; and provide cool, outside air to cool your building. This is the preferred method of low-ambient cooling. When coupled to CO 2 sensors, Economizers can provide even more savings by coupling the ventilation air to only that amount required. Economizers are available, installed and tested by the factory, with either enthalpy or dry-bulb temperature inputs. There are also models for electromechanical as well as direct digital controllers. Additional sensors are available as accessories to optimize the economizers. Reduce service and/or installation costs by including a convenience outlet in your specification. Carrier will install this service feature at our factory. Provides a convenient, 15 amp, 115v GFCI receptacle with Wet in Use cover. The powered option allows the installer to power the outlet from the line side of the disconnect or load side as required by code. The unpowered option is to be powered from a separate 115/120v power source. Non -fused Disconnect Economizers include gravity controlled, barometric relief equalizes building pressure and ambient air pressures. This can be a cast effective solution to prevent building pressurization. CO 2 Sensor Improves productivity and saves money by working with the economizer to intake only the correct amount of outside air for ventilation. As occupants fill your building, the CO 2 sensor detects their presence through increasing CO 2 levels, and opens the economizer appropriately. When the occupants leave, the CO 2 levels decrease, and the sensor appropriately closes the economizer. This intelligent control of the ventilation air, called Demand Control Ventilation (DCV) reduces the overall load on the rooftop, saving money. Smoke Detectors Trust the experts. Smoke detectors make your application safer and your job easier. Carrier smoke detectors immediately shut down the rooftop unit when smoke is detected. They are available, installed by the factory, for supply air, return air, or both. Louvered Hail Guards Sleek, louvered panels protect the condenser coil from hail damage, foreign objects, and incidental contact. This OSHA-compliant, factory-installed, safety switch allows a service technician to locally secure power to the rooftop. Power Exhaust with Barometric Relief. Superior internal building pressure control. This field-installed accessory may eliminate the need for costly, external pressure control fans. PremierLinkt This CCN controller regulates your rooftop s performance to tighter tolerances and expanded limits, as well as facilitates zoning systems and digital accessories. It also unites your Carrier HVAC equipment together on one, coherent CCN network. The PremierLink can be factory-installed, or easily field-installed. RTU Open, Multi -protocol Controller Connect the rooftop to an existing BAS without needing complicated translators or adapter modules using the RTU Open controller. This new controller speaks the 4 most common building automation system languages (Bacnet, Modbus, N2, and Lonworks). Use this controller when you have an existing BAS. Besides the 4 protocols, it also communicates with a Carrier Open system (I-Vu and VVT). 6

7 Time Guard II Control Circuit FACTORY OPTIONS AND/OR ACCESSORIES (cont.) Motormaster Head Pressure Controller This accessory protects your compressor by preventing short -cycling in the event of some other failure, prevents the compressor from restarting for 30 seconds after stopping. Not required with PremierLinkr, RTU-MP,or authorized commercial thermostats. Motorized 2 -Position Damper The new Carrier 2-position, motorized outdoor air damper admits up to 100% outside air. Using reliable, gear-driven technology, the 2-position damper opens to allow ventilation air and closes when the rooftop stops, stopping unwanted infiltration. Manual OA Damper Manual outdoor air dampers are an economical way to bring in ventilation air. The dampers are available in 25% and 50% versions. Optional Humidi -MiZer Adaptive Dehumidification System Carrier s Humidi-MiZer adaptive dehumidification system is an all-inclusive factory installed option that can be ordered with any WeatherMaster rooftop unit. This system expands the envelope of operation of Carrier s WeatherMaster rooftop products to provide unprecedented flexibility to meet year round comfort conditions. The Humidi-MiZer adaptive dehumidification system has the industry s only dual dehumidification mode setting. The Humidi -MiZer system includes two new modes of operation. The WeatherMaster rooftop coupled with the Humidi-MiZer system is capable of operating in normal design cooling mode, subcooling mode, and hot gas reheat mode. Normal design cooling mode is when the unit will operate under its normal sequence of operation by cycling compressors to maintain comfort conditions. Subcooling mode will operate to satisfy part load type conditions when the space requires combined sensible and a higher proportion of latent load control. Hot Gas Reheat mode will operate when outdoor temperatures diminish and the need for latent capacity is required for sole humidity control. Hot Gas Reheat mode will provide neutral air for maximum dehumidification operation. Hinged Access Panels Allows access to unit s major components with specifically designed hinged access panels. Panels are: filter, control box, fan motor and compressor. The Motormaster motor controller is a low ambient, head pressure controller kit that is designed to maintain the unit s condenser head pressure during periods of low ambient cooling operation. This device should be used as an alternative to economizer free cooling not when economizer usage is either not appropriate or desired. The Motormaster will either cycle the outdoor-fan motors or operate them at reduced speed to maintain the unit operation, depending on the model. Winter Start Kit The winter start kit by Carrier extends the low ambient limit of your rooftop to 25_F (-4_C). The kit bypasses the low pressure switch, preventing nuisance tripping of the low pressure switch. Other low ambient precautions may still be prudent. Alternate Motors and Drives Some applications need larger horsepower motors, some need more airflow, and some need both. Regardless of the case, your Carrier expert has a factory installed combination to meet your application. A wide selection of motors and pulleys (drives) are available, factory installed, to handle nearly any application. Thru -the -Base Connections Thru-the -base connections, available as either an accessory or as a factory option, are necessary to ensure proper connection and seal when routing wire and piping through the rooftop s basepan and curb. These couplings eliminate roof penetration and should be considered for gas lines, main power lines, as well as control power. Electric Heaters Carrier offers a full-line of field-installed accessory heaters. The heaters are very easy to use, install and are all pre-engineered and certified. 7

Outdoor sound data is measure in accordance with AHRI. 2. Measurements are expressed in terms of sound power. Do not compare these values to sound pressure values because sound pressure depends on specific environmental factors which normally do not match individual applications. Sound power values are independent of the environment and therefore more accurate. 3.
