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 WeatherMakert units are field-convertible to horizontal air flow; no special adapter curbs or kits are necessary. Convertible airflow design makes it easy to adjust to unexpected job-site complications. Lighter units make easy replacement. These Carrier 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, master 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 51mm (2-in.) filters standard. 2

6 FACTORY OPTIONS AND/OR ACCESSORIES Economizer (dry -bulb or enthalpy) PremierLinkt 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. 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. Non -fused Disconnect This OSHA-compliant, factory-installed, safety switch allows a service technician to locally secure power to the rooftop. 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 Multi -Protocol 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. Time Guard II Control Circuit 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 Open Multi -Protocol Controller, or authorized commercial thermostats. Filter or Fan Status Switches Use these differential pressure switches to detect a filter clog or indoor fan motor failure. When used in conjunction with a compatible unit controller/thermostat, the switches will activate an alarm to warn the appropriate personnel. 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. Motormaster Head Pressure Controller 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. 6

7 FACTORY OPTIONS AND/OR ACCESSORIES (cont.) Winter Start Kit Electric Heaters The winter start kit by Carrier extends the low ambient limit of your rooftop to -4_C (25_F). The kit bypasses the low pressure switch, preventing nuisance tripping of the low pressure switch. Other low ambient precautions may still be prudent. 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. 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. 7

23 APPLICATION DATA Min operating ambient temp (cooling): Sizing a rooftop In mechanical cooling mode, your Carrier rooftop can safely operate down to an outdoor ambient temperature of 4_C (40_F) and -4_C (25_F), with an accessory winter start kit. It is possible to provide cooling at lower outdoor ambient temperatures by using less outside air, economizers, and/or accessory low ambient kits. Max operating ambient temp (cooling): The maximum operating ambient temperature for cooling mode is 52_C (125_F). While cooling operation above 52_C (125_F) may be possible, it could cause either a reduction in performance, reliability, or a protective action by the unit s internal safety devices. Min and max airflow (cooling mode): To maintain safe and reliable operation of your rooftop, operate within the cooling airflow limits. Operating above the max may cause blow-off, undesired airflow noise, or airflow related problems with the rooftop unit. Operating below the min may cause problems with coil freeze-up. Airflow: All units are draw-though in cooling mode. Outdoor air application strategies: Economizers reduce operating expenses and compressor run time by providing a free source of cooling and a means of ventilation to match application changing needs. In fact, they should be considered for most applications. Also, consider the various economizer control methods and their benefits, as well as sensors required to accomplish your application goals. Please contact your local Carrier representative for assistance. Motor limits, break horsepower (BHP): Due to Carrier s internal unit design, air path, and specially designed motors, the full horsepower (maximum continuous BHP) band, as listed in Table 5 and 6, can be used with the utmost confidence. There is no need for extra safety factors, as Carrier s motors are designed and rigorously tested to use the entire, listed BHP range without either nuisance tripping or premature motor failure. Bigger isn t necessarily better. While an air conditioner needs to have enough capacity to meet the load, it doesn t need excess capacity. In fact, having excess capacity typically results in very poor part load performance and humidity control. Using higher design temperatures than ASHRAE recommends for your location, adding safety factors to the calculated load, and rounding up to the next largest unit, are all signs of oversizing air conditioners. Oversizing can cause short -cycling, and short cycling leads to poor humidity control, reduced efficiency, higher utility bills, drastic indoor temperature swings, excessive noise, and increased wear and tear on the air conditioner. Rather than oversizing an air conditioner, wise contractors and engineers right -size or even slightly undersize air conditioners. Correctly sizing an air conditioner controls humidity better; promotes efficiency; reduces utility bills; extends equipment life, and maintains even, comfortable temperatures. Low ambient applications When equipped with a Carrier economizer, your rooftop unit can cool your space by bringing in fresh, cool outside air. In fact, when so equipped, accessory low-ambient kit may not be necessary. In low ambient conditions, unless the outdoor air is excessively humid or contaminated, economizer-based free cooling is the preferred less costly and energy conscious method. In low ambient applications where outside air might not be desired (such as contaminated or excessively humid outdoor environments), your Carrier rooftop can operate to ambient temperatures down to -29_C (-20_F) using the recommended accessory Motormaster low ambient controller. Winter start Carrier s winter start kit extends the low ambient limit of your rooftop to -4_C (25_F). The kit bypasses the low pressure switch, preventing nuisance tripping of the low pressure switch. Other low ambient precautions may still be prudent. 23
