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 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. Carrier 3--12.5 ton 50TC 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:

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) t hrough 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 t o 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.

FACTORY OPTIONS AND/OR ACCESSORIES

Economizer (dry--bulb or enthalpy)

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. W h en coupled to CO 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

levels decrease, and

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--MP, Multi --protocol Controller

Connect the rooftop to an existing BAS without needing complicated translators or adapter modules using the RTU--MP 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--MP,or authorized commercial thermostats.

Filter or Fan Status Switches

Smoke Detectors

Trust the experts. Smoke detect ors make your application safer a nd 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.

Convenience Outlet (powered or un--powered)

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

This OSHA--compliant, factory--installed, safety switch allows a service technician to locally secure power to the rooftop.

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.

Optional Humidi--MiZert Adaptive Dehumidification System

Carrier’s Humidi--MiZer adaptive dehumidification system is an all-- inclusive factory--installed option that can be ordered with any WeatherMaker 50TC--04--07 rooftop unit.

This system expands the envelope of operation of Carrier’s WeatherMaker 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 WeatherMaker 50TC--04--07 ooftop 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 ope ration 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.

Motormaster Head Pressure Controller

The Motormaster motor controller is a low ambient, head pressure controller kit that is designed to m aintain 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 tri pping 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.

APPLICATION DATA

Min operating ambient temp (cooling):

In mechanical cooling mode, your Carrier rooftop can safely operate down to an outdoor ambient temperature of 40_F(4_C) and 25_F(--4_C), 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 115_F(46_C). While cooling operation above 115_F(46_C) 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):

Sizing a rooftop

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 locati on, 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 slight ly 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 Carrie r 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 --20_F(--29_C) using t he recommended accessory Motormaster low ambient controller.

50TC

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, 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.

Winter start

Carrier’s winter start kit 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.

SELECTION PROCEDURE (WITH 50TC*A07 EXAMPLE)

I. Determine cooling and heating loads.

Given: Mixed Air Drybulb 80_F(27_C) Mixed Air Wetbulb 67_F(19_C) Ambient Drybulb 95_F(35_C) TC

Load

SHC

Load

Vertical Supply Air 2100 CFM External Static Pressure 0.66 in.wg Electrical Characteristics 230--3--60

II. Make an initial guess at cooling tons.

Refrig. tons = TC Refrig. tons = 69.0 / 12 = 5.75 tons

In this case, start by looking at the 50TC*A07.

50TC

III. Look up the rooftop’s TC and SHC.

Table 12 shows that, at the application’s supply air CFM, mixed air and ambient temperatures, the 50TC*A07 supplies: TC SHC

= 73.7 MBH

Load

= 54.4 MBH.

IV. Calculate the building Latent Heat Load.

V. Calculate RTU Latent Heat Capacity

LC = TC -- SHC LC = 73.7 MBH -- 54.4 MBH = 19.3 MBH

VI. Compare RTU capaciti es to loads.

2,3

Compare the rooftop’s SHC and LC to the building’s Sensible and Latent Heat Loads.

VII. Select factory options (FIOP)

Local code requires an economizer for any unit with TC larger than 65.0 MBH.

VIII. Calculate the total static pressure.

External static pressure 0.66 in. wg Sum of FIOP/Accessory static +0.14 in.

Total Static Pressure 0.80 in. wg

IX. Look up the Indoor Fan RPM & BHP.

Table 33 shows, at 2100 CFM & ESP= 0.8, RPM = 1268 & BHP = 1.52

X. Determine electrical requirements

Table 52 shows the MCA and MOCP of a 50TC*A07 (without convenience outlet) as:

MCA = 30.5 amps & MOCP = 45 amps Min. Disconnect Size: FLA = 30 & LRA = 157.

NOTES:

1. Selection software by Carrier saves time by performing many of the steps above. Contact your Carrier sales representative for assistance.

2. Selecting a unit with a SHC slightly lower than the SHC SHC’s will help control indoor humidity, and prevent temperature swings.

3. If the rooftop’s capacity meets the Sensible Heat Load, butnottheLatentHeatLoad.

4. Indoor Fan Motor efficiency is available in Table 46. Use the decimal form in the equation eg. 80% =.8.
