Your Carrier rooftop unit (RTU) was designed by customers for customers. With "no-strip screw" collars, handled access panels, and more we've made your unit easy to install, easy to maintain, easy to use, and easy to love. Easy to install: All WeatherMaker units are convertible to horizontal air flow; no special adapter curbs are necessary. Convertible airflow design makes it easy to adjust to unexpected job-site complications. Lighter units make easy replacement. Carrier 3-6 ton TC rooftops fit on existing Carrier curbs dating back to 1989.Also,our large control box gives you room to work and room to mount Carrier accessory controls. Easy to maintain: Carrier's easy access handles 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: Carrier's newly designed, master terminal board 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.

There is no need for extra The maximum operating ambient temperature for cooling safety factors, as Carrier's motors are designed and mode is 115°F (46°C). While cooling operation above rigorously tested to use the entire, listed BHP range 115°F (46°C) may be possible, it could cause either a without either nuisance tripping or premature motor reduction in performance, reliability, or a protective action failure. by the unit's internal safety devices.

Oversizing the air conditioner leads to poor run time by providing a free source of cooling and a humidity control, reduced efficiency, higher utility bills, means of ventilation to match application changing needs. larger indoor temperature swings, excessive noise, and In fact, they should be considered for most applications. increased wear and tear on the air conditioner. 16 Rather than oversizing an air conditioner, engineers should "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. Please contact your local Carrier representative for assistance. Low ambient applications The optional Carrier economizer can adequately 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 energy conscious method. ener*;Y 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 -20°F(-29°C) using the recommended accessory Motormaster low ambient controller. 17 SELECTION PROCEDURE (WITH 48TC**07 EXAMPLE)l I.

Interpolation is permissible. Do not extrapolate. 2. External static pressure is the static pressure difference between the return duct and the supply duct plus the static pressure caused by any FIOPs or accessories. 3. Tabular data accounts for pressure loss due to clean filters, unit casing, and wet coils. Factory options and accessories may add static pressure losses, as shown in Table 14. Selection software is available, through your salesperson, to help you select the best motor/drive combination for your application. 4. The Fan Performance tables offer motor/drive recommendations. In cases when two motor/drive combinations would work, Carrier recommended the lower horsepower option. 5. For information on the electrical properties of Carrier's motors, please see the Electrical information section of this book. 6.

As a result, the indoor-fan contactor (IFC) Electro-mechanical units with an economizer and the compressor contactor (Cl) are energized, causing the indoor-an motor (IFM), compressor #1, and outdoor Cooling— fan to start. If the unit has 2 stages of cooling, the When free cooling is not available, the compressors will thermostat will additionally energize Y2. The Y2 signal be controlled by the zone thermostat. When free cooling is will energize compressor contactor #2 (C2), causing available, the outdoor-air damper is modulated by the compressor #2 to start. Regardless of the number of EconoMi$er IV control to provide a 50°F(10°C) to 55°F stages, the outdoor-an motor runs continuously while unit (13°C) mixed-air temperature into the zone. As the mixed is cooling. air temperature fluctuates above 55°F (13°C)or below Heating 50°F (10°C) dampers will be modulated (open or close) to bring the mixed-air temperature back within control. If NOTE: WMaster (48TC) units have either 1 or 2 mechanical cooling is utilized with free cooling, the stages of gass heat. outdoor-air damper will maintain its current position at When the thermostat calls for heating, power is sent to W the time the compressor is started. If the increase in on the Integrated Gas Controller (IGC) board. An LED cooling capacity causes the mixed-air temperature to drop (light-emitting diode) on the IGC board turns on and below 45°F (7°C), then the outdoor-air damper position remains on during normal operation. A check is made to will be decreased to the minimum position. If the ensure that the rollout switch and limit switch are closed mixed-air temperature continues to fall, the outdoor-air and the induced-draft motor is running. If the check was damper will close. Control returns to normal once the successful, the induced-draft motor is energized, and mixed-air temperature rises above 48°F (9°C). The when its speed is satisfactory, as proven by the "hall power exhaust fans will be energized and de-energized, if effect" sensor, the ignition activation period begins. The installed, as the outdoor-air damper opens and closes. burners will ignite within 5 seconds. If the burners do not light, there is a 22-second delay before another 5-second If field-installed accessory CO2 sensors are connected to attempt.

If free interrupting the flow of gas to the main burners. cooling can be used as determined from the appropriate changeover command (switch, dry bulb, enthalpy curve, 41 differential dry bulb, or differential enthalpy), then the control will modulate the dampers open to maintain the mixed-air temperature set point at 50°F (10°C) to 55°F (13°C). If there is a further demand for cooling (cooling second stage - Y2 is energized), then the control will bring on compressor stage 1 to maintain the mixed-air temperature set point. The EconoMi$er IV damper will be open at maximum position. EconoMi$er IV operation is limited to a single compressor. Heating The sequence of operation for the heating is the same as an electromechanical unit with no economizer. The only difference is how the economizer acts. The economizer will stay at the Economizer Minimum Position while the evaporator fan is operating. The outdoor-air damper is closed when the indoor fan is not operating. 42 GUIDE SPECIFICATIONS - 48TC**04-07 Note about this specification: Carrier wrote this specification in the 2004 version of the "Masterformat" as published by the Construction Specification Institute.
