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 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 3-- 12.5 ton 50HC 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) 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.

50HC
CATEGORY
FACTORY OPTIONS AND/OR ACCESSORIES
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 CO2 sensors, Economizers can
provide even more savings by coupling the ventilation air
to only that amount required.
50HC
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.
CO2 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 CO2 sensor detects their presence through increasing
CO2 levels, and opens the economizer appropriately.
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.
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
When the occupants leave, the CO2 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.
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.
Smoke Detectors
RTU Open, Multi--protocol Controller
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.
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).
Louvered Hail Guards
Sleek, louvered panels protect the condenser coil from
hail damage, foreign objects, and incidental contact.

FACTORY OPTIONS AND/OR ACCESSORIES (cont.)
Time Guard II Control Circuit
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.
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.
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 50HC04-- 14 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 50HC04-- 14 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.
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.
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.

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. A ---weighted sound ratings filter out very high and very
low frequencies, to better approximate the response of
“average” human ear. A ---weighted measurements for

Section 313 of the Energy Independence and Security Act of 2007 (EISA 2007) mandates that the efficiency of general purpose motors we use in our Light
Commercial Rooftops rated at 5.0 HP and larger be increased on or after December 19, 2010. We will offer both high and standard efficient motors until
inventory is depleted and then shift over solely to the high efficient motors only.

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
35_F (-- 2_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.
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.
Max operating ambient temp (cooling):
The maximum operating ambient temperature for cooling
mode is 125_F (52_C). While cooling operation above
125_F (52_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):
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.
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 - 20_F (-- 29_C) using the
recommended accessory Motormaster low ambient
controller.
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.

II.
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)
69.0 MBH
TCLoad
SHCLoad
51.0 MBH
Vertical Supply Air
2100 CFM
External Static Pressure
0.66 in.wg
Electrical Characteristics
230-- 3-- 60
Make an initial guess at cooling tons.
Refrig. tons = TCLoad / 12 MBH per ton
Refrig. tons = 69.0 / 12 = 5.75 tons
In this case, start by looking at the 50HC*A07.
III. Look up the rooftop’s TC and SHC.
Table 15 shows that, at the application’s supply air
CFM, mixed air and ambient temperatures, the
50HC*A07 supplies:
TCLoad = 73.6 MBH
SHCLoad = 53.3 MBH.
IV.
Calculate the building Latent Heat Load.
LCLoad = TCLoad - SHCLoad
LCLoad = 69.0 MBH - 51.0 MBH = 18.0 MBH
V.
Calculate RTU Latent Heat Capacity
LC = TC - SHC
LC = 73.6 MBH - 53.3 MBH = 20.3 MBH
VI. Compare RTU capacities 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
Sum of FIOP/Accessory static
Total Static Pressure
0.66 in. wg
+0.05 in. wg
0.71 in. wg
IX. Look up the Indoor Fan RPM & BHP.
Table 44 shows, at 2100 CFM & ESP= 0.71,
RPM = 680 & BHP = 0.97
X.
Convert BHP (Step IX) into fan motor heat.
Fan Motor Heat = 2.546*097/.80 efficiency.
Fan Motor Heat = 1.98 MBH
Deduct this value from the gross capacity values for
net capacity.
XI. Determine electrical requirements
Table 75 shows the MCA and MOCP of a
50HC*A07 (without convenience outlet) as:
MCA = 32 amps & Breaker size = 50 amps
Min. Disconnect Size: FLA = 31 & LRA = 148.

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
SHCLoad is often better than oversizing. Slightly lower
SHC’s will help control indoor humidity, and prevent temperature swings.
3. If the rooftop’s capacity meets the Sensible Heat Load,
but not the Latent Heat Load.
4. Indoor Fan Motor efficiency is available in Table 23. Use
the decimal form in the equation eg. 80% =.8.

General fan performance notes:
1. 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 25. 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 motors, please see the Electrical information section of this
book.
6. For more information on the performance limits of Carrier motors, see the application data section of this book.
7. The EPACT (Energy Policy Act of 1992) regulates energy requirements for specific types of indoor fan motors. Motors
regulated by EPACT include any general purpose, T-- frame (three-- digit, 143 and larger), single-- speed, foot mounted,
polyphase, squirrel cage induction motors of NEMA (National Electrical Manufacturers Association) design A and B,
manufactured for use in the United States. Ranging from 1 to 200 Hp, these continuous-- duty motors operate on 230
and 460 volt, 60 Hz power. If a motor does not fit into these specifications, the motor does not have to be replaced by
an EPACT compliant energy-- efficient motor. Variable-- speed motors are exempt from EPACT compliance requirements.

1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the
overcurrent protective device for the unit shall be fuse or HACR
breaker. Canadian units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage
is greater than 2%. Use the following formula to determine the
percentage of voltage imbalance.
% Voltage Imbalance
= 100 x
max voltage deviation from average voltage
Example: Supply voltage is 230-3-60
average voltage
Average Voltage =
=
(224 + 231 + 226)
3
=
681
3
227
Determine maximum deviation from average voltage.
(AB) 227 – 224 = 3 v
(BC) 231 – 227 = 4 v
(AC) 227 – 226 = 1 v
Maximum deviation is 4 v.
Determine percent of voltage imbalance.
% Voltage Imbalance
= 100 x
4
227
= 1.76%
This amount of phase imbalance is satisfactory as it is below the maximum
allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.

Example: Supply voltage is 230-3-60
AB = 224 v
BC = 231 v
AC = 226 v
Average Voltage =
=
3
=
681
3
227
Determine maximum deviation from average voltage.
(AB) 227 – 224 = 3 v
(BC) 231 – 227 = 4 v
(AC) 227 – 226 = 1 v
Maximum deviation is 4 v.
Determine percent of voltage imbalance.
% Voltage Imbalance
= 100 x
4
227
= 1.76%
max voltage deviation from average voltage
average voltage
(224 + 231 + 226)
This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more than 2%,
contact your local electric utility company immediately.

NOTES:
Terminal board schematic layout does not match actual terminal board to simplify circuit traces. Ensure designated jumpers on terminal board are cut when adding smoke detectors,
phase loss relay and remote shutdown.
ECONOMIZER NOTES:
1. 620 ohm, 1 watt, 5% resister should be removed only when using differential enthalpy or dry bulb.
2. If a separate field ---supplied 24V transformer is used for the IAQ sensor power supply, it cannot have the secondary of the transformer grounded.
3. For field ---installed remote minimum position POT, remove black wire jumper between P and P1 and set control minimum position POT to the minimum position.

SEQUENCE OF OPERATION
General
Electro--mechanical units with no economizer
Cooling —
When the thermostat calls for cooling, terminals G and Y1
are energized. As a result, the indoor-- fan contactor (IFC)
and the compressor contactor (C1) are energized, causing
the indoor-- an motor (IFM), compressor #1, and outdoor
fan to start. If the unit has 2 stages of cooling, the
thermostat will additionally energize Y2. The Y2 signal
will energize compressor contactor #2 (C2), causing
compressor #2 to start. Regardless of the number of
stages, the outdoor-- fan motor runs continuously while
unit is cooling.
If field-- installed accessory CO2 sensors are connected to
the EconoMi$er IV control, a demand controlled
ventilation strategy will begin to operate. As the CO2
level in the zone increases above the CO2 setpoint, the
minimum position of the damper will be increased
proportionally. As the CO2 level decreases because of the
increase in fresh air, the outdoor-- air damper will be
proportionally closed. For EconoMi$er IV operation, there
must be a thermostat call for the fan (G). If the unit is
occupied and the fan is on, the damper will operate at
minimum position. Otherwise, the damper will be closed.
When the EconoMi$er IV control is in the occupied mode
and a call for cooling exists (Y1 on the thermostat), the
control will first check for indoor fan operation. If the fan
is not on, then cooling will not be activated. If the fan is
on, then the control will open the EconoMi$er IV damper
to the minimum position.
Units have either 1 or 2 stages of electric heat. When the
thermostat calls for heating, power is applied to the W1
terminal at the unit. The unit control will energize the
indoor fan contactor and the first stage of electric heat. On
units with two-- stage heating, when additional heating is
required, the second stage of electric heat (if equipped)
will be energized when power is applied at the W2
terminal on the unit.
On the initial power to the EconoMi$er IV control, it will
take the damper up to 2 1/2 minutes before it begins to
position itself. After the initial power-- up, further changes
in damper position can take up to 30 seconds to initiate.
Damper movement from full closed to full open (or vice
versa) will take between 1 1/2 and 2 1/2 minutes. If free
cooling can be used as determined from the appropriate
changeover command (switch, dry bulb, enthalpy curve,
differential dry bulb, or differential enthalpy), then the
control will modulate the dampers open to maintain the
mixed-- air temperature setpoint at 50_F (10_C) to 55_F
(13_C). If there is a further demand for cooling (cooling
second stage - Y2 is energized), then the control will
bring on compressor stage 1 to maintain the mixed-- air
temperature setpoint. The EconoMi$er IV damper will be
open at maximum position. EconoMi$er IV operation is
limited to a single compressor.
Electro--mechanical units with an economizer
Heating
Heating
NOTE: The 50HC is sold as cooling only. If electric
heaters are required, use only factory-- approved electric
heaters. They will operate as described below.
Cooling —
When free cooling is not available, the compressors will
be controlled by the zone thermostat. When free cooling is
available, the outdoor-- air damper is modulated by the
EconoMi$er IV control to provide a 50_F (10_C) to 55_F
(13_C) mixed-- air temperature into the zone. As the mixed
air temperature fluctuates above 55_F (13_C) or below
50_F (10_C) dampers will be modulated (open or close)
to bring the mixed-- air temperature back within control. If
mechanical cooling is utilized with free cooling, the
outdoor-- air damper will maintain its current position at
the time the compressor is started. If the increase in
cooling capacity causes the mixed-- air temperature to drop
below 45_F (9_C), then the outdoor-- air damper position
will be decreased to the minimum position. If the
mixed-- air temperature continues to fall, the outdoor-- air
damper will close. Control returns to normal once the
mixed-- air temperature rises above 48_F (9_C). The
power exhaust fans will be energized and de-- energized, if
installed, as the outdoor-- air damper opens and closes.
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.
Optional Humidi-- MiZer Dehumidification System
Units with the factory-- equipped Humidi-- MiZer option
are capable of providing multiple modes of improved
dehumidification as a variation of the normal cooling
cycle. The Humidi-- MiZer option includes additional
valves in the liquid line and discharge line of each
refrigerant circuit, a small reheat condenser coil
downstream of the evaporator, and Motormaster
variable-- speed control of some or all outdoor fans.
Operation of the revised refrigerant circuit for each mode
is described below.
NOTE: x = refrigerant circuit A, B, or C.

The sequence below describes the sequence of operation
for an electro-- mechanical unit with and without a factory
installed EconoMi$ert IV (called “economizer” in this
sequence). For information regarding a direct digital
controller,
see
the
start-- up,
operations,
and
troubleshooting manual for the applicable controller.
SEQUENCE OF OPERATION (cont.)
Normal Cooling
Reheat2 (Hot Gas Reheat Mode) --50HC04--14
Refrigerant flows from the outdoor condenser through the
normally open Cooling Valve (CV.x) to the expansion
device. Reheat1 Valve (RH1.x) and Reheat2 Valve
(RH2.x) are closed.
This mode provides maximum latent cooling with little to
no sensible capacity. This mode can operate to provide
dehumidification when there is no cooling demand. Like
Reheat1 mode, refrigerant flows from the outdoor
condenser, through the normally open Reheat1 Valve
(RH1.x), and through the reheat condenser coil to the
expansion device. The Cooling Valve (CV.x) is closed.
Reheat2 Valve (RH2.x) is open which provides some
compressor discharge gas to the reheat condenser to
further increase the reheat of the evaporator airstream.
50HC
Reheat1 (Subcooling Mode) -- 50HC04--14
This mode increases latent cooling and decreases sensible
cooling compared to normal cooling. Refrigerant flows
from the outdoor condenser, through the normally open
Reheat1 Valve (RH1.x), and through the reheat condenser
coil to the expansion device. Cooling Valve (CV.x) and
Reheat2 Valve (RH2.x) are closed.
