Unit sizes 008-016 offer lower utility
costs through part-load operation using 2 stages of cooling.
Quiet and efficient operation is provided by belt-driven indoor fans (standard on all units over 5 tons). The beltdriven indoor fan is equipped with
variable-pitch pulleys which allow adjustment within the rpm ranges of the
factory-supplied pulleys. Increased operating efficiency is achieved through
computer-designed coils featuring staggered internally enhanced copper
tubes. Fins are ripple-edged for
strength, lanced, and double waved for
higher heat transfer.

Durable, dependable
construction
Designed for durability in any climate,
the weather-resistant cabinets are constructed of galvanized steel and bonderized, and all exterior panels are coated with a prepainted baked enamel finish. The paint finish is non-chalking,
and is capable of withstanding ASTM
B117 500-hour Salt Spray Test. All internal cabinet panels are primed, permitting longer life and a more attractive appearance for the entire unit.
In addition, all size 004-012 units
are designed with a single, continuous
top piece to eliminate any possible
leaks. Totally enclosed condenser-fan
motors and permanently lubricated
bearings provide additional unit
dependability.
Patented state-of-the-art Chronotemp™ defrost system uses time
and temperature to keep the outdoor
coil frost-free for economical, dependable operation. The Chronotemp defrost
board can be easily configured for defrost cycles every 30, 50, or 90 minutes.
Dependable 4-way valve operation safely and efficiently accomplishes cycle reversals, defrost, and normal
operation.
Easy installation and
conversion
All units are shipped in the vertical duct configuration for fit-up to
standard roof curbs. (3 different curb
sizes fit unit sizes 004-007, 008-012,
and 014-016 respectively.) The contractor can order and install the roof
curb early in the construction stage,
before decisions on size requirements
are made.
All units feature a base rail design
with forklift slots and rigging holes for
easier maneuvering. Durable packaging protects all units during shipment
and storage.
The units can be easily converted
from a vertical to a horizontal duct configuration by relocating the panels supplied with the unit.
To convert 004-012 units from
vertical to horizontal discharge, simply
relocate 2 panels. The same basic unit
can be used for a variety of applications and can be quickly modified at
the jobsite.
To convert 014-016 units from
vertical to horizontal discharge, use the
optional horizontal supply/return
adapter roof curb.
Convenient duct openings in the
unit basepans permit side-by-side or
concentric duct connections (see Application Data section) without requiring
internal unit modification (014,016
only).
NOTE: On units using horizontal supply and return, the accessory barometric relief or power exhaust MUST be
installed on the return ductwork.
Thru-the-bottom service connection
capability comes standard with the
rooftop unit to allow power and control wiring to be routed through the
unit’s basepan, thereby minimizing
roof penetrations (to prevent water
leaks). Power and control connections
are made on the same side of the unit
to simplify installation.
The non-corrosive sloped condensate drain pan permits either an external horizontal side condensate drain
(outside the roof curb) or an internal
vertical bottom drain (inside the roof
curb). Both options require an external, field-supplied P-trap.
Standard 2-in. throwaway filters
are easily accessed through a removable panel located above the air intake
hood. No tools are required to change
unit filters.
All 004-012 units are designed
with a single, continuous top
piece to eliminate leaking at the seams
or gasketing.
Belt-driven indoor-fan motors allow maximum on-site flexibility without
changing motors or drives.
Field-installed accessory electric
heaters are available in a wide range of
capacities. An available single-point
wiring kit makes installation simple.
Low voltage wiring connections
are easily made due to the large terminal board which is located for quick,
convenient access.
In addition, color-coded wires permit
easy tracing and diagnostics.
Proven compressor reliability
Design techniques feature computerprogrammed balance between compressor, condenser, and evaporator.
Carrier-specified hermetic compressors are equipped with compressor
overcurrent and overtemperature protection to ensure dependability.
All units have Carrier’s exclusive
Acutrol™ (004-012) or TXV metering
device (014-016) which precisely controls refrigerant flow, preventing slugging and flood-back, while maintaining optimum unit performance. Refrigerant filter driers are standard.
Standard low ambient cooling operation to 25 F; optional head pressure control kit available for outdoor
ambient conditions to –20 F.
Integrated economizers and
outdoor air
Optional economizers and manual
outdoor-air dampers introduce outdoor
air which mixes with the conditioned
air, improving indoor-air quality and often reducing energy consumption.
During a first stage call for cooling, if
the outdoor-air temperature is below
the economizer control changeover set
point, the discharge-air sensor modulates the economizer outdoor-air
damper open to take advantage of free
cooling provided by the outside air.
When second-stage cooling is called
for, the compressor is energized in addition to the economizer. If the
outdoor-air temperature is above the
changeover set point, the first stage
of compression is activated and the
economizer stays at vent position.
Durablade economizer operation is
controlled by a dry-bulb thermostat
that senses outdoor-air temperature.
Accessory upgrade kits allow for
either outdoor air enthaply changeover
or for more precise differential
enthalpy control.
Units can also utilize the factory or
field-installed EconoMi$er. The
EconoMi$er is microprocessor controlled and incorporates a parallel, opposed-blade gear driven damper system. In addition, it has a spring return
built into the damper actuator to provide reliable close-on-power-loss. The
EconoMi$er comes equipped with up
to 90% barometric relief capability for
high outdoor airflow applications on
004-012 units only. Optional fieldinstalled Barometric Relief package is
available for use on 014-016 size
units.
In addition, the EconoMi$er twostage power exhaust accessory can be
utilized to help maintain proper building pressure (004-012 units only). Single stage power exhaust is available for
unit sizes 014-016 as a field-installed
accessory.
For units without economizer, yearround ventilation is enhanced by a
manual outdoor-air damper. On 004012 units, a 25% or 50% manual
damper is available as a field-installed
accessory. Unit sizes 014-016 are
equipped with a standard manual 25%
damper.
Service options
Servicing a rooftop unit has never
been easier with the new factoryinstalled service options for these rooftop units. These options include the
following:
• Hinged access panels are provided
for the filter/indoor-fan motor, compressors, indoor fan, and control
box areas. Quick access to major
components is accomplished by
simply unlatching and swinging
open the various panels. Each
hinged panel is permanently
mounted to the unit, thereby eliminating the concern of a dropped or
wind-blown panel puncturing delicate roof materials. The 4 extended
access panels are also equipped
with ‘‘tie back’’ retaining devices to
hold the door in the open position
while servicing the unit.
• An external, covered, 115-v
Ground Fault Interrupt (GFI) receptacle is provided as a convenient
power source for drills, lights, refrigerant recovery units, or other electrical service tools. Simply connect
the outlet to a field-supplied and
properly fused branch circuit power
supply.
• An integral non-fused disconnect
switch within the rooftop unit reduces installation time, labor and
material costs. Safety is assured by
an interlock which prevents access
to the control box unless the switch
is in the OFF position. In addition,
the externally mounted handle
incorporates power lockout capability to further protect service
personnel.
Carrier PremierLink™ Controls
add reliability, efficiency, and
simplification
The PremierLink direct digital controls
can be ordered as a factory-installed
option or as a field-installed accessory.
Designed and manufactured exclusively
by Carrier, the controls can be used to
actively monitor and control all modes
of operations, as well as monitor the
following diagnostics and features: unit
number, zone temperature, zone set
point, zone humidity set point, discharge air temperatures, fan status,
stages of heating, stages of cooling,
damper position, outdoor-air temperature, outdoor humidity level, filter status, fire shutdown status, IAQ set
point, enthalpy status, differential enthalpy status, heat/cool lockout, CFM
set point, pre-occupancy purge, economizer controls and early morning
warm-up.
This controller has a 38.4K baud
communications capability and is compatible with ComfortLink™ Controls,
CCN and ComfortVIEW™ Software.
The Scrolling Marquee and Navigator
3
Features/Benefits (cont)
are optional tools that can be used for
programming and monitoring the unit
for optimal performance. The addition of the Carrier CO2 sensor in the
conditioned space provides ASHRAE
62-99 compliance and Demand Control Ventilation.
The PremierLink peer-to-peer, internet ready, communicating control is
designed specifically for Constant Volume and Variable Volume and Temperature applications. This comprehensive
controls system allows all Carrier 3 to
25 ton rooftops to be daisy chained together on a roof to create a fully functional HVAC (heating, ventilation, and
air conditioning) automation system.
Carrier Apollo microprocessor controls add reliability,
efficiency, and simplification.
Apollo controls are designed and manufactured exclusively by Carrier, the
controls can be used to actively monitor and control all modes of operation.
The Apollo communicating controls
are factory-installed into the rooftop
unit control box, and come equipped
with built-in diagnostic capabilities.
Light-emitting diodes (LEDs) simplify
troubleshooting by indicating thermostat commands for both stages of heating and cooling, evaporator fan operation, and economizer operation. The
Apollo communicating controls are designed to work specifically with the
Carrier TEMP and VVT® (variable volume and temperature) thermostats.
The standard rooftop control system is
readily adaptable to all conventional
and programmable thermostats. In addition, units are suitable for integration
into building monitor control systems if
required. This system gives the units
the flexibility to communicate with almost any thermostat or building control system.
Indoor-air quality begins with
Carrier rooftops
Sloped condensate pans minimize
biological growth in rooftop units in accordance with ASHRAE (American
Society of Heating, Refrigeration, and
Air Conditioning Engineers) Standard
62. Two-inch filters with optional dirty
filter indicator switch provide for greater particle reduction in the return air.
The face-split evaporator coils improve
the dehumidification capability of standard units, maximize building humidity
control.
Optional proportional reacting
CO2 sensor is available with the
EconoMi$er outdoor air damper option/accessory to aid the IAQ benefits.
Energy$Recycler — the IAQ
solution for today’s “tight”
buildings
Indoor-air quality (IAQ) generally refers
to the level of pollutants inside a building. These pollutants include cigarette
smoke, carbon dioxide exhaled by
occupants, radon gas, car exhaust,
paint fumes, and odors.
Concern over increased indoor air
pollutants has been spurred by several
issues: 1) changes in new building construction methods and retrofit of older
buildings have reduced air infiltration
rates; 2) Synthetic materials release airborne particles, odors, and chemicals;
and 3) HVAC (heating, ventilation, and
air conditioning) systems that bring in
minimal fresh air.
In 1989, IAQ concerns caused
ASHRAE to recommend increased
ventilation for all public buildings. Simply introducing fresh air into a building,
however, is not always practical or cost
effective. Additional ventilation can
overload HVAC systems and increase
energy costs.
Carrier’s 62AQ Energy$Recycler
unit solves this dilemma by providing
increased fresh air while keeping increased costs to a minimum. In addition, the Energy$Recycler helps reduce humidity levels, which helps to
prevent deterioration of building materials and retards the growth of mold
and mildew.
The 62AQ Energy$Recycler unit
provides the best solution to retaining
the energy-conserving benefits of today’s tighter building construction
while improving indoor-air quality.
The Energy$Recycler can be integrally mounted in the size 004-012
units or free standing for all units.

TEMP systems
A TEMP System is a network of communicating Carrier
TEMP System Thermostats and rooftop, factory-mounted
Apollo direct digital controls, each serving its own zone
and heating/cooling unit. Networking allows your building
manager to easily access each of your systems from a
single location...whether they are in the same building or
located throughout town.
The TEMP System’s inherently flexible, modular base
design supports the exact number of independent, single
TEMP SYSTEM THERMOSTAT (WITH TIMECLOCK)
zone systems you require...no more, no less, no
compromises.
Ideal for department stores, small office buildings, fast
food chains, schools, and hotels, a TEMP System is a
cost-effective way to maintain comfortable building
environments.
NOTE: Unit temperature rise must not be exceeded for
proper unit operation.

VVT Systems are dedicated to total building comfort.
Carrier thermostats, zone dampers, and HVAC equipment
with factory-mounted direct digital controls continually

and personalized comfort for all occupants.
18
Through the use of communicating electronic controls,
VVT Systems are able to provide the comfort of a multiple
zone system while using the installation, operating and
maintenance economics of single zone equipment...
virtually putting an end to the cost vs comfort compromise.
NOTE: Unit temperature rise must not be exceeded for
proper unit operation.
VVT® application guidelines (50HJQ014,016)
The installer is responsible for ensuring that the bypass
controller is configured and the system is balanced so that
the minimum airflow is higher than 300 cfm/ton (40 L/s
per kW). To accomplish proper configuration set the System Setup Enable Function (Category 5, option 7) to ON.
This will close the bypass damper and force all of the zone
dampers to open. The air balance should be completed
after the zones minimum airflow has been set, verifying the
total airflow through the equipment is above the minimum
airflow level.
VVT bypass design layout — Particular attention must
be given to bypass duct layout. It has been a source of VVT
system operating problems when neglected. Proper layout
consists of the five factors:
1. Proper location of the bypass
2. Adequately sizing the bypass
3. Avoiding short-circuiting of supply and return air
4. Proper location of the static pickup
5. Facilitating the mixing of bypass air with return air
The recommended location of the bypass damper is for
it to duct the bypass air either into the ceiling plenum or
into unoccupied spaces. See figure below for a typical installation. This method of installation prevents interference
with intended fresh air intake through the unit and economizer operation.
It is highly recommended that the bypass damper is not
ducted between the rooftop unit’s supply duct and the return duct as shown in the diagram below. This type of installation may result in the return duct becoming pressurized causing many problems such as:
• Preventing intended fresh intake for ventilation from
entering the unit.
• Preventing proper operation of the economizer and
causing mechanical cooling to energize needlessly.
• Preventing proper mixing of bypass air and return air
resulting in low return temperatures in cooling, and
high return temperature in heating.
General — The VVT system is a zoning system that
allows a single-zone heating/cooling system to operate as
a multiple-zone system. For this system to function correctly and not adversely affect the reliability of the heating/
cooling system, the information provided here must be
followed.
There are two parts of the VVT system installation that
are important for successful operation: the bypass damper
and the HVAC (Heating, Ventilation, and Air-Conditioning)
equipment configuration settings. The following information will provide important details for these two items as
well as specific instructions for the 50HJQ014,016 rooftop units. This information is intended as a supplement to
the Installation Instructions shipped with the equipment.
Bypass damper — The bypass damper and controller
serve to accomplish two functions in the VVT system.
First, the bypass damper keeps supply duct pressure and
velocity down at partial load. This permits the VVT system
to utilize standard low-velocity, low-pressure supply duckweeds, duct insulation, and duct sealing methods. Without
the bypass damper, the restriction of the zone dampers
that are closing at partial loads would cause duct static
pressure to climb, adding stress to all supply duct materials.
Accompanying velocity and noise would create problems
in the conditioned space.
Second, when the bypass damper is set up correctly, it
ensures that the airflow through the HVAC equipment remains above the minimum required levels. (See capacity
ratings for minimum heating cfm required for proper operation of the rooftop heating system. These minimum heating
cfm levels must be maintained during all phases of heating
operation. The heating cfm values take precedence over
listed minimum cooling cfm values.) This permits the use of
constant volume rooftop units on VVT applications. Without the bypass damper, the restriction of the zone dampers
that are closing at partial loads will reduce the airflow
through the unit to below the minimum levels.

If the diversity within the space does not vary much, then
bypass can be installed as shown in the diagram below successfully. Care must be taken to ensure that maximum bypass air at part load conditions does not exceed 25% of the
full load airflow.
The bypass junction must be installed with sufficient
duct length between it and the unit to allow complete mixing of the bypass air an the return air. Without adequate
mixing, comfort control will be lost as the equipment will
be cycled off and equipment failures may result if left at the
extremes. When the HVAC equipment uses an economizer, a back-draft damper needs to be installed between
the connection of the bypass duct and the closet room return air grille.
Bypass controller considerations — Besides considering the minimum and maximum cfm’s required, as in the
system design guidelines, the following are a few system
concerns to consider when designing a bypass damper in a
VVT® system.
1. The maximum amount of air being bypassed should
match an equivalent amount of cfm of unconditioned
air based on the ability of the system to unload. For
example: If the equipment has two compressors and
one unloader, then the refrigeration portion of the
equipment is capable of unloading to about 25% of
unit capacity. Therefore the designer should make
sure the system will use 25% of the system cfm for
comfort conditioning and bypass 75% of the conditioned air before energizing the compressors. This
will ensure that the system will have enough return air
mixing with the bypassed air to keep the compressor
running. Make sure that the compressor does not
cycle too frequently based on the leaving air temperature limits since this could lessen the reliability of the
compressors. The heating equipment will only be able
to unload 50%. The system may be designed to cycle
based on the leaving air temperature limits depending
on the rise designed in the heat exchanger and the
amount of outside air being brought in. Although this
is not efficient, the equipment reliability should not be
a problem.
2. Be sure to verify the pressure drop across the bypass
when in full bypass. The bypass should maintain the
system pressure without causing 100% of the air to
be bypassed. Tables are provided in the Comfort Systems Controls manual which will indicate the sound
and performance criteria of Carrier dampers. Calculate bypass of 4500 cfm on a unit with a nominal airflow of 6000 cfm and external static pressure of
0.50 in. wg. The ZD-16 has two entries in the table
of 1475 and 1574. Three ZD-16 dampers in parallel
could be used for the job. The 16-in. damper will not
operate full open to produce these results, so it will be
necessary to balance the system and set the maximum
damper position to achieve these results in the field.
3. These airflows were tested at 0.50 in. wg and provided NC levels of 42 and 44 respectively. A noise
criteria of around 40 would be acceptable for a ducted
bypass with internally lined duct but probably not for
externally lined ducts since the noise could be transmitted to the return registers. Duct design is important to consider in bypass design since improper
noise levels can require the use of other dampers to
achieve the same bypassed cfm with reduced noise.
For the example above, two 35D, 16-in. dampers
can move the same air at a NC level of 29.5 Radiated. These dampers can be ordered with sound
attenuators to lessen radiated noise also. Use the
damper test criteria to make the selection.
4. If designing a system with an economizer, be sure to
include power exhaust on the equipment to prevent
conditioned air from migrating out the return registers
into the space in a over pressure condition. This condition can be identified since the doors will most likely
stand open. The same condition can occur if there is
a large exhaust system in the building for labs or
restrooms.

Monitor thermostat configuration — The monitor
thermostat controls the operation of its own zone and of
each associated zone controller. The monitor thermostat
determines system operation from the information received from each device that it controls. The monitor thermostat must be configured for proper control of the
system. Part of the configuration is Category 4.0, which
deals with HVAC settings. The Category 4.0 HVAC Equipment table shows the default settings for this category.
NOTE: In the majority of cases only categories 4.5, 4.6,
4.7, 4.8 and 4.15 will require changing by the installer.
Leaving-air temperature (LAT) monitoring must be always used. This function prevents the HVAC equipment
from operating in a range that will cause equipment safety
trips, leading to shortened equipment life.
There are tradeoffs involved in the selection of the system mode demand, monitor thermostat configurations
4.15. Lower setting levels tend to improve comfort but
tend to increase operating costs and reduce equipment reliability. Buildings that have large core areas that are likely
to make a call when others are not should use lower system
mode demand levels. For buildings with zones that have
more similar load patterns from zone to zone, or smaller
zones or more uniformly sized zones, a higher setting
should be used.

DX coil sensor installation — The use of a DX (direct
expansion) coil sensor is recommended. The DX temperature sensor should be installed in the ductwork as close to
the equipment as possible. Care must be taken not to have
the sensor within “line of sight” of the equipment’s heating
elements. Radiation from the heat can cause the sensor to
read an elevated reading.
The majority of the units referred to by these application
guidelines are two compressor units. The monitor thermostat has the ability to read only one DX coil sensor, which
can only be installed within the equipment on a single compressor unit. All of the LAT settings have been determined
assuming supply duct temperatures versus coil temperatures. Be sure the DX coil sensor option is turned on.
Category 5.6 under the monitor configurations, should be
ON.
Application guidelines — The units are constant volume units and will require the use a bypass damper and
controller. Refer to page 19 for details regarding the use
and installation of the bypass damper.
These units use a TXV metering device. Use of optional,
factory-installed hot gas bypass (HGBP) is recommended
for VVT® applications to aid in low load performance
operation.
Electrical connection from the VVT system to the units
will be the typical thermostat connections from the relay
pack to the unit.
Carrier Apollo controls
The Apollo direct digital controls are ordered as a factoryinstalled option. Designed and manufactured exclusively by
Carrier, the controls can be used to actively monitor and
control all modes of operation, as well as to monitor
evaporator-fan status, filter status, indoor-air quality (humidity and carbon dioxide), supply-air temperature,
outdoor-air temperature, and field-provided sensors.
The Apollo communicating controls are factory-installed
into the rooftop unit control box, and come equipped with
built-in diagnostic capabilities. Light-emitting diodes (LEDs)
simplify troubleshooting by indicating thermostat commands for both stages of heating and cooling, evaporator
fan operation, and economizer operation. The Apollo
communicating controls are designed to work specifically
with the Carrier TEMP and VVT® (variable volume and
temperature) thermostats. The Apollo controls allow the
use of an IAQ (Indoor-Air Quality) sensor. The Apollo controls, combined with Carrier thermostats, incorporate a
5-minute recycle delay timer between modes of operation
to prevent short cycling.
The standard rooftop control system is readily adaptable
to all conventional and programmable thermostats. In addition, units are suitable for integration into building monitor
control systems if required. This system gives the units the
flexibility to communicate with almost any thermostat or
building control system.

Operating sequence — 50TFQ004-012 and
50HJQ004-012
Cooling, units without economizer — When thermostat calls for cooling, terminals G and Y1 are energized.
The indoor-fan contactor (IFC), reversing valve solenoid
(RVS1) and compressor contactor no. 1 (C1) are energized
and indoor-fan motor, compressor no. 1, and outdoor fans
start. The outdoor-fan motor(s) run continuously while unit
is cooling. On 50TFQ008-012 units, if the thermostat
calls for a second stage of cooling by energizing Y2, compressor contactor no. 2 (C2) and reversing valve solenoid
(RVS2) are energized and compressor no. 2 starts.
Heating, units without economizer (50TFQ004007 and 50HJQ004-007) — Set system switch at
AUTO. or HEAT position. Set thermostat at desired
temperature.
When the thermostat calls for heat, the IFC, outdoor-fan
contactor (OFC), and compressor contactor are energized.
The RVS is deenergized and switches position, and the indoor fan, outdoor fan, and compressor are energized.
If the thermostat calls for a second stage of heat, the
heater contactor (HC) is energized and starts the electric
heaters.
When the space temperature approaches the heating
temperature set point, heating stages cycle off. The reversing valve solenoid is reenergized.
Heating, units without economizer (50TFQ008012 and 50HJQ008,012) — Upon a request for heating from the space thermostat, terminal W1 will be energized with 24 v. The IFC, outdoor-fan contactor (OFC),
C1, and C2 will be energized. The reversing valves switch
position and the indoor fan, outdoor fan, compressor
no. 1, and compressor no. 2 are energized.
If the space temperature continues to fall while W1 is energized, W2 will be energized with 24 v, and the heater
contactor(s) (HC) will be energized, which will energize the
electric heater(s).
When the space thermostat is satisfied, W2 will be deenergized first, and the electric heater(s) will be deenergized.
Upon a further rise in space temperature, W1 will be
deenergized, and the reversing valve solenoids (RVS1 and
RVS2) will be energized.

Cooling, units with Durablade economizer — When
the outdoor-air temperature is above the outdoor-air thermostat (OAT) setting and the room thermostat calls for
cooling, compressor contactor no. 1 is energized to start
compressor no. 1 and the outdoor-fan motor(s). RVS1 (reversing valve solenoid) is energized. The indoor-fan motor
is energized and the economizer damper moves to the
minimum position. Upon a further call for cooling, compressor contactor no. 2 will be energized (50TFQ008-012
and 50HJQ008,012), starting compressor no. 2. RVS2 is
energized. After the thermostat is satisfied, the damper
moves to the fully closed position.
When the outdoor-air temperature is below the OAT setting and the thermostat calls for cooling, the economizer
dampers move to the minimum position. If the supply-air
temperature is above 57 F, the damper continues to open
until it reaches the fully open position or until the supplyair temperature drops below 52 F.
When the supply-air temperature falls to between 57 F
and 52 F, the damper will remain at an intermediate open
position. If the supply-air temperature falls below 52 F, the
damper will modulate closed until it reaches the minimum
position or until the supply-air temperature is above 52 F.
When the thermostat is satisfied, the damper will move to
the fully closed position.
If the outdoor air alone cannot satisfy the cooling requirements of the conditioned space, economizer cooling
is integrated with mechanical cooling, providing secondstage cooling. Compressor no. 1 and the outdoor fan will
be energized and the position of the economizer damper
will be determined by the supply-air temperature. Compressor no. 2 (50TFQ008-012 and 50HJQ008,012) is
locked out.
When the second stage of cooling is satisfied, the compressor, RVS2, and outdoor-fan motor(s) will be deenergized. The damper position will be determined by the
supply-air temperature.
When the first stage of cooling is satisfied, the damper
will move to fully closed position.

Controls (cont)
Cooling, units with EconoMi$er (50TFQ004-007
and 50HJQ004-007) — When the outdoor-air temperature (OAT) is above the ECON SP set point and the room
thermostat calls for Stage 1 cooling (R to G + Y1), the
indoor-fan motor (IFM) is energized and the EconoMi$er
damper modulates to minimum position. The compressor
contactor is energized to start the compressor and outdoorfan motor (OFM) and RVS1 (reversing valve solenoid). After the thermostat is satisfied, the damper modulates to the
fully closed position when the IFM is deenergized.
When the OAT is below the ECON SP setting and the
room thermostat calls for Stage 1 cooling (R to G + Y1),
the EconoMi$er modulates to the minimum position when
the IFM is energized. The EconoMi$er provides Stage 1 of
cooling by modulating the return and outdoor-air dampers
to maintain a 55 F supply air set point. If the supply-air
temperature (SAT) is greater than 57 F, the EconoMi$er
modulates open, allowing a greater amount of outdoor air
to enter the unit. If the SAT drops below 53 F, the outdoor
air damper modulates closed to reduce the amount of outdoor air. When the SAT is between 53 and 57 F, the
EconoMi$er maintains its position.
If outdoor-air alone cannot satisfy the cooling requirements of the conditioned space, and the OAT is above the
MECH CLG LOCKOUT set point, the EconoMi$er integrates free cooling with mechanical cooling. This is accomplished by the strategies below.
NOTE: Compressor has a 2-minute Minimum On, Minimum Off, and Interstage delay timer.
1. If Y1 is energized, and the room thermostat calls for
Y2 (2-stage thermostat), the compressor and OFM
are energized. The EconoMi$er damper is maintained at its current position.
2. If Y1 is energized for more than 20 minutes, and Y2
is not energized (whether or not a 2-stage thermostat
is used), the compressor and OFM are energized.
The EconoMi$er damper is maintained at its current
position.
3. If Y1 is energized, and the compressor is already
energized (see Step 2) and the room thermostat calls
for Y2, the compressor continues to operate.
4. If compressor is energized and the thermostat is satisfied, the compressor, the OFM, and IFM are deenergized and the EconoMi$er modulates closed.
When the OAT is below the MECH CLG LOCKOUT set
point, the compressors remain off.
Cooling, units with EconoMi$er (50TFQ008-014
and 50HJQ008,012) — When the outdoor-air temperature (OAT) is above the ECON SP set point and the room
thermostat calls for Stage 1 cooling (R to G + Y1), the
indoor-fan motor (IFM) is energized and the EconoMi$er
damper modulates to minimum position. The compressor
contactor is energized to start the compressor and outdoorfan motor (OFM) and RVS1 (reversing valve solenoid). After the thermostat is satisfied, the damper modulates to the
fully closed position when the IFM is deenergized.
26
When the OAT is below the ECON SP setting and the
room thermostat calls for Stage 1 cooling (R to G + Y1),
the EconoMi$er modulates to the minimum position when
the IFM is energized. The EconoMi$er provides Stage 1 of
cooling by modulating the return and outdoor-air dampers
to maintain a 55 F supply air set point. If the supply-air
temperature (SAT) is greater than 57 F, the EconoMi$er
modulates open, allowing a greater amount of outdoor air
to enter the unit. If the SAT drops below 53 F, the outdoor
air damper modulates closed to reduce the amount of outdoor air. When the SAT is between 53 and 57 F, the
EconoMi$er maintains its position.
If outdoor-air alone cannot satisfy the cooling requirements of the conditioned space, and the OAT is above the
MECH CLG LOCKOUT set point, the EconoMi$er integrates free cooling with mechanical cooling. This is accomplished by the strategies below.
NOTE: Compressors have a 2-minute Minimum On, Minimum Off, and Interstage delay timer.
1. If Y1 is energized, and the room thermostat calls for
Y2 (2-stage thermostat), compressor no. 1 and OFM
are energized. The EconoMi$er damper is maintained at its current position.
2. If Y1 is energized for more than 20 minutes, and Y2
is not energized (whether or not a 2-stage thermostat
is used), compressor no. 1 and OFM are energized.
The EconoMi$er damper is maintained at its current
position.
3. If Y1 is energized, and compressor no. 1 is already
energized (see Step 2) and the room thermostat calls
for Y2, compressor no. 1 continues to operate. If Y2
remains energized for more than 20 minutes, compressor no. 2 is energized.
NOTE: Compressor no. 2 cannot be energized unless
there is a signal for Y2 from the space thermostat.
4. If compressor no. 2 is energized, and the Y2 signal
from the thermostat is satisfied, compressor no. 1
and 2 are deenergized. Reasserting Y2 will start compressor no. 1 and (after a 20-minute interstage delay)
compressor 2.
5. If compressor no. 1 is energized and the thermostat is
satisfied, compressor no. 1, the OFM, and IFM are
deenergized and the EconoMi$er modulates closed.
Heating, units with economizer — Upon a call for
heat through W1, the IFC energizes to start the evaporator
fan and the economizer damper blade opens to the minimum position. If the accessory two-position damper is
used, the outdoor-air damper opens to the minimum position whenever the evaporator fan runs. If unit is equipped
with 2 stages of heat, when additional heat is needed a call
is made through W2.
As space temperature approaches the heating temperature set point, heating stages cycle off. Economizer or twoposition damper returns to fully closed position.
Defrost (50TFQ004-007 and 50HJQ004-007) —
As frost builds up on the outdoor coil, the coil temperature
drops below 28 F. When this outdoor-coil temperature
drop is sensed by the defrost thermostat (DFT) and the defrost timer is at the end of a timed period (adjustable at 30,
50, or 90 minutes), the unit operates in a defrost cycle
controlled by the defrost timer and thermostat. During this
cycle, the reversing valve solenoid (RVS) is energized and
the outdoor fan shuts off. The electric heaters (if installed)
will be energized.
The unit continues to defrost until the coil temperature
as measured by DFT reaches 65 F, or the duration of defrost cycle completes a 10-minute period.
At the end of the defrost cycle, the electric heaters (if installed) and the reversing valve will be deenergized, and the
outdoor-fan motor will be energized. The unit will now operate in the Heating mode.
If the thermostat is satisfied during a defrost cycle, the
unit will continue in the Defrost mode until the time or temperature constraints are satisfied.
Defrost (50TFQ008-012 and 50HJQ008,012) —
When the temperature of the outdoor coil drops below 28 F
as sensed by the defrost thermostat (DFT2) and the defrost
timer is at the end of a timed period (adjustable at 30, 50,
or 90 minutes), reversing valve solenoids (RVS1 and RVS2)
are energized and the OFC is deenergized. This switches
the position of the reversing valves and shuts off the outdoor fan. The electric heaters (if installed) will be energized.
The unit continues to defrost until the coil temperature
as measured by DFT2 reaches 65 F, or the duration of defrost cycle completes a 10-minute period.
During the Defrost mode, if circuit 1 defrosts first, RVS1
will oscillate between Heating and Cooling modes until the
Defrost mode is complete.
At the end of the defrost cycle, the electric heaters (if installed) will be deenergized; the reversing valves switch and
the outdoor-fan motor will be energized. The unit will now
operate in the Heating mode.
If the space thermostat is satisfied during a defrost cycle,
the unit will continue in the Defrost mode until the time or
temperature constraints are satisfied.
Sequence of operation — 50HJQ014,016
Cooling, units without economizer — With unit main
power on, set thermostat to COOL position and desired
room temperature. Set fan switch at AUTO. (on demand)
or ON (continuous) position.
On a rise in room temperature, cooling contactor no. 1
in the thermostat closes. The indoor and outdoor fan motors start. If the 5-minute compressor time-delay (CTD) on
the defrost board (DB) is satisfied, then compressor no. 1
(50HJQ016) or unloaded compressor (50HJQ014) contactor is energized and compressor will start. Compressor
cycles on demand of the thermostat to satisfy room conditions. Each time the cooling contactor no. 1 opens, the
CTD starts the 5-minute delay.
On 50HJQ016 units, with an additional rise in room
temperature, cooling contactor no. 2 in the thermostat closes, energizing compressor contactor no. 2. Compressor
no. 2 starts and cycles on demand of the thermostat to satisfy the occupied space demands.
On 50HJQ014 units, compressor runs fully loaded on a
call for second-stage cooling.
Cooling, units with economizer — Upon a call for
cooling, when outdoor ambient temperature is above the
temperature control setting, the indoor and outdoor fans
and compressor(s) energize. The economizer damper
moves to vent position.
Upon a first-stage call for cooling, when outdoor ambient temperature is below the temperature control setting,
the indoor fan starts and economizer damper modulates to
maintain mixed-air temperature. The compressor(s) remains off.
Upon a second-stage call for cooling, compressor no. 1
(50HJQ016) or loaded compressor (50HJQ014) is energized and mechanical cooling is integrated with economizer cooling. Compressor no. 2 (50HJQ016) is locked out. If
the air temperature is below 50 F, a cooling lockout switch
prevents the compressor(s) from running.
When supply-air temperature drops below a fixed set
point, the economizer damper modulates to maintain the
temperature at the fixed set point.
A freeze protection thermostat (FPT) is located on the
indoor coil. It detects frost build-up and turns off the compressor(s), allowing the coil to clear. Once frost has melted,
the compressor can be reenergized.
Heating, units without economizer — With unit main
power on, set thermostat at HEAT position and desired
room temperature. Set fan switch at AUTO. (on demand)
or ON (continuous) position.
On a drop in room temperature, heating contactor no. 1
in the thermostat closes, energizing heat relay (HR), reversing valve relay (RVR), reversing valve solenoids (RVS1 and
RVS2) and compressor no. 2 contactor. Compressor (size
014) or compressor no. 2 (size 016) and indoor and outdoor fan motors start. If the 5-minute CTD on the DB is
satisfied, then compressor no. 1 contactor is energized and
compressor no. 1 will start.
On units equipped with electric heat, when additional
heat is needed, heating contactor no. 2 in the thermostat
closes, energizing W2.
Heating, units with economizer — With unit main
power on, set thermostat at HEAT position and desired
room temperature. Set fan switch at AUTO. (on demand)
or ON (continuous) position.
On a drop in room temperature, heating contactor no. 1
in the thermostat closes, energizing heat relay (HR), reversing valve relay (RVR), reversing valve solenoids (RVS1 and
RVS2) and compressor no. 2 contactor. Compressor no. 2
(016) and indoor and outdoor fan motors (014,016) start.
If the 5-minute CTD on the DB is satisfied, then compressor (014) or compressor no. 1 (016) contactor is energized
and compressor (014) or compressor no. 1 (016) will start.
The outdoor-air damper stays at vent position while the indoor fan is operating.
27
Controls (cont)
On units equipped with electric heat, when additional
heat is needed, heating contactor no. 2 in the thermostat
closes, energizing W2.
Defrost cycle — When the temperature of the outdoor
coil drops below 28 F as sensed by the defrost thermostat
(DFT1 or DFT2), the defrost timer starts. At the end of a
timed period (field set at 30, 50, or 90 minutes), the defrost cycle will begin. The defrost board energizes terminals
O and W2, energizes the defrost relay (DR), deenergizes
the reversing valve solenoids (RVS1 and RVS2), and energizes the electric heat. The outdoor-fan motor will stop.
The unit continues to defrost either until the coil temperature as measured by DFT1 or DFT2 reaches 65 F, or until
unit completes a 10-minute defrost cycle.
During the defrost mode, when a circuit defrosts, RVS will
oscillate between heating and cooling modes until defrost
mode is complete. This will prevent the head pressure
from getting too high.
At the end of the defrost cycle, the electric heaters (if applicable) will be deenergized, the reversing valve solenoids will
be energized, and the outdoor fans will start.
Automatic changeover — When the system selection
switch is set at AUTO. position, unit automatically changes
from heating operation to cooling operation when the
temperature of the conditioned space rises to the cooling
level setting. When the temperature of the conditioned
space falls to the heating level setting, unit automatically
changes from cooling to heating operation (with a 3 F
deadband in between).
Continuous air circulation — Turn unit power on. Set
system control at OFF position. Set fan switch at ON position. The indoor-fan contactor is energized through the
thermostat switch and the indoor fan runs continuously.
Cycle-LOC™ protection — If unit operation is interrupted by an open high-pressure switch, low-pressure switch,
indoor coil freezestat, or by compressor internal line-break
device (overcurrent or overtemperature), and compressor
is calling for either cooling or heating, Cycle-LOC protection device simultaneously locks out unit and lights a warning light on the thermostat. Restart the unit by manually
turning thermostat to OFF and then to ON position. If any
of the protective devices opens again, the unit continues to
lock out until corrective action is taken.
NOTE: If the unit fails to operate due to compressor overcurrent condition, restart by manually resetting circuit
breakers at the unit. Restart cannot be accomplished at the
room thermostat.
Emergency heat — If compressor is inoperative due to a
tripped safety device (high or low pressure, indoor coil
freezestat, overcurrent, or overtemperature), the CycleLOC device locks out the compressor and lights a warning
light on the room thermostat. When the switch is on (thermostat is set to the EM HT position), compressor circuit
and outdoor thermostats are bypassed, and the second
stage of thermostat energizes the indoor blower and the
electric resistance heaters.

Selection procedure (with 50TFQ005 example)
17,000 Btuh
= 5.0 kW of heat required.
3413 Btuh/kW
Enter the Electric Heating Capacities table (page 68)
for 50TFQ005 at 208/230, 3 phase. The 6.5-kW
heater at 240 v most closely satisfies the heating
required. To calculate kW at 230 v, use the Multiplication Factors table.
6.5 kW x .92 = 5.98 kW
6.5 kW x .92 x 3413 = 20,410 Btuh
Total unit heating capacity is 38,410 Btuh (18,000
+ 20,410).
IV Determine fan speed and power requirements
at design conditions.
Before entering Fan Performance tables, calculate
the total static pressure required based on unit components. From the given and the Pressure Drop
tables, find:
External static pressure
Durablade economizer
Electric heat
.45 in. wg
.05 in. wg
.09 in. wg
Total static pressure
.59 in. wg
Enter the Fan Performance table for 50TFQ005 vertical discharge. At 1600 cfm and 230-v high speed,
the standard motor will deliver 0.76 in. wg static
pressure, 723 watts, and 0.64 brake horsepower
(bhp). This will adequately handle job requirements.
V Determine net capacities.
Capacities are gross and do not include the effect of
indoor-fan motor (IFM) heat.
Determine net cooling capacity as follows:
Net capacity = Total capacity – IFM heat
= 49,900 Btuh – (723 Watts x 3.413
Btuh/Watts)
= 49,900 Btuh – 2468 Btuh
= 47,432
Net sensible capacity = 33,900 Btuh – 2468 Btuh
= 31,432 Btuh
Integrated heating capacity is maximum (instantaneous) capacity less the effect of frost on the outdoor coil and the heat required to defrost it.
Therefore, net capacity is equal to 38,410 Btuh, the
total heating capacity determined in Step III.
39
50TFQ004-012
I Determine cooling and heating loads at
design conditions.
Given:
Required Cooling Capacity (TC) . . . . .38,000 Btuh
Sensible Heat Capacity (SHC) . . . . . .24,000 Btuh
Required Heating Capacity . . . . . . . .35,000 Btuh
Outdoor Entering-Air Temperature db . . . . . . .95 F
Outdoor-Air Winter Design Temperature . . . . . 0° F
Indoor-Air Winter Design Temperature . . . . . .70 F
Indoor-Air
Temperature . . . 80 F edb (entering air, dry bulb)
67 F ewb (entering air, wet bulb)
Indoor-Air Quantity . . . . . . . . . . . . . . . . 1600 cfm
External Static Pressure . . . . . . . . . . . .0.45 in. wg
Electrical Characteristics (V-Ph-Hz) . . . . . 230-3-60
II Select unit based on required cooling capacity.
Enter Cooling Capacities table at outdoor entering
temperature of 95 F, indoor air entering at
1600 cfm and 67 F ewb. The 50TFQ005 unit will
provide a total cooling capacity of 49,900 Btuh and
a sensible heat capacity of 33,900 Btuh.
For indoor-air temperature other than 80 F edb, calculate sensible heat capacity correction, as required,
using the formula found in Note 3 following the
cooling capacities tables.
NOTE: Unit ratings are gross capacities and do not
include the effect of indoor-fan motor heat. To calculate net capacities, see Step V.
III Select electric heat.
Enter the Instantaneous and Integrated Heating Ratings table at 1600 cfm. At 70 F return indoor air
and 0° F air entering outdoor coil, the integrated
heating capacity is 18,000 Btuh. (Select integrated
heating capacity value since deductions for outdoorcoil frost and defrosting have already been made.
No correction is required.)
The required heating capacity is 35,000 Btuh.
Therefore, 17,000 Btuh (35,000 – 18,000) additional electric heat is required.
Determine additional electric heat capacity in kW.

NOTES:
1. Direct interpolation is permissible. Do
not extrapolate.
2. The following formulas may be used:
tldb = tedb –
sensible capacity (Btuh)
1.10 x cfm
tlwb = Wet-bulb temperature corresponding to enthalpy of air
leaving indoor coil (hlwb)
hlwb = hewb –
total capacity (Btuh)

Where: hewb = Enthalpy of air entering
evaporator coil
3. The SHC is based on 80 F edb temperature of air entering indoor coil.
Below 80 F edb, subtract (corr factor x
cfm) from SHC.
Above 80 F edb, add (corr factor x
cfm) to SHC.

tlwb = Wet-bulb temperature corresponding to enthalpy of air leaving indoor coil (hlwb )
hlwb = hewb –
total capacity (Btuh)
4.5 x cfm
Where: hewb = Enthalpy of air entering evaporator coil
3. The SHC is based on 80 F edb temperature of air entering indoor
coil.
Below 80 F edb, subtract (corr factor x cfm) from SHC.
Above 80 F edb, add (corr factor x cfm) to SHC.
NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
tldb = tedb –
4700/0.21
sensible capacity (Btuh)

*Standard motor drive range: 685 to 935 rpm. Alternate motor drive
range: 835 to 1085 rpm. High static motor drive range: 830 to
1130 rpm. All other rpms require field-supplied drive.
Refer to this page for general Fan Performance notes.
NOTES:
1. Boldface indicates field-supplied drive is required.
2.
indicates high-static motor and drive are required.
3. Maximum usable watts input is 2120 with standard motor, 2615 with
alternate motor, and 4400 for the high-static motor. Maximum
continuous bhp is 2.40 with standard motor, 2.90 with alternate
motor and 5.25 with high-static motor.
GENERAL NOTES FOR FAN PERFORMANCE TABLES
1. Extensive motor and electrical testing on these units ensures that
the full range of the motor can be utilized with confidence. Using
your fan motors up to the wattage ratings shown will not result in
nuisance tripping or premature motor failure. Unit warranty will not
be affected. For additional information on motor performance, refer
to Indoor-Fan Motor Performance table on page 69.
2. Values include losses for filters, unit casing, and wet coils. See
page 66 for accessory/FIOP (factory-installed option) static pressure information.
3. Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.
4. Interpolation is permissible. Do not extrapolate. (Belt drive units
only.)

(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
*Heaters are field installed only.
†Used to determine minimum disconnect size per NEC.
**Heater capacity (kW) is based on heater voltage of 208 v, 240 v,
480 v, and 575 v. If power distribution voltage to unit varies from rated
heater voltage, heater kW will vary accordingly.
††Fuse or HACR circuit breaker.
***Optional disconnect switch is unavailable.
NOTES:
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.
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 percent
of voltage imbalance.
% Voltage Imbalance
max voltage deviation from average voltage
= 100 x
average voltage
78
Determine percent of voltage imbalance.
7
% Voltage Imbalance = 100 x
457
= 1.53%
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.

Selection procedure (with 50HJQ005 example)
14,600 Btuh
3413 Btuh/kW
= 4.3 kW of heat required.
Enter the Electric Heating Capacities table for
50HJQ005 at 208/230, 3 phase. The 6.5-kW
heater at 240 v most closely satisfies the heating
required. To calculate kW at 230 v, use the Multiplication Factors table.
6.5 kW x .92 = 5.98 kW
6.5 kW x .92 x 3413 = 20,410 Btuh
Total unit heating capacity is 40,810 Btuh (20,400
+ 20,410).
IV Determine fan speed and power requirements at design conditions.
Before entering Fan Performance tables, calculate
the total static pressure required based on unit components. From the given and the Pressure Drop
tables, find:
External static pressure
Durablade economizer
Electric heat
Total static pressure
.45 in. wg
.05 in. wg
.09 in. wg
.59 in. wg
Enter the Fan Performance table for 50HJQ005
vertical discharge. At 1600 cfm and 230-v, the
standard motor will deliver 1.2 in. wg static pressure
and 1.15 brake horsepower (bhp). This will adequately handle job requirements.
NOTE: Convert bhp to Watts using the formula
found in the note following the Indoor-Fan Motor
Efficiency table.
For this example:
746 x Bhp
Watts =
Motor Efficiency
Watts =
746 x 1.15
.75
Watts = 1144
V Determine net capacities.
Capacities are gross and do not include the effect of
indoor-fan motor (IFM) heat.
Determine net cooling capacity as follows:
Net capacity = Total capacity – IFM heat
= 47,400 Btuh – (1144 Watts x 3.413
Btuh/Watts)
= 47,400 Btuh – 3904 Btuh
= 43,496
Net sensible capacity = 32,800 Btuh – 3904 Btuh
= 28,896 Btuh
Integrated heating capacity is maximum (instantaneous) capacity less the effect of frost on the outdoor coil and the heat required to defrost it.
Therefore, net capacity is equal to 40,810 Btuh, the
total heating capacity determined in Step III.
93
50HJQ004-012
50TFQ004-012
I Determine cooling and heating requirements
at design conditions:
Given:
Required Cooling Capacity (TC) . . . . .38,000 Btuh
Sensible Heat Capacity (SHC). . . . . . .24,000 Btuh
Required Heating Capacity. . . . . . . . .35,000 Btuh
Outdoor Entering-Air Temperature . . . . . . . . .95 F
Outdoor-Air Winter Design Temperature . . . . . 0° F
Indoor-Air Winter Design Temperature . . . . . .70 F
Indoor Entering-Air
Temperature . . . 80 F edb (entering air, dry bulb),
67 F ewb (entering air, wet bulb)
Indoor-Air Quantity . . . . . . . . . . . . . . . . 1600 cfm
External Static Pressure . . . . . . . . . . . . 0.45 in. wg
Electrical Characteristics (V-Ph-Hz) . . . . . 230-3-60
II Select unit based on required cooling capacity.
Enter Cooling Capacities table at outdoor entering
temperature of 95 F, indoor air entering at
1600 cfm and 67 F ewb. The 50HJQ005 unit will
provide a total cooling capacity of 47,400 Btuh and
a sensible heat capacity of 32,800 Btuh.
For indoor-air temperature other than 80 F edb, calculate sensible heat capacity correction, as required,
using the formula found in Note 3 following the
cooling capacities tables.
NOTE: Unit ratings are gross capacities and do not
include the effect of indoor-fan motor heat. To calculate net capacities, see Step V.
III Select electric heat.
Enter the Instantaneous and Integrated Heating Ratings table at 1600 cfm. At 70 F return indoor air
and 0° F air entering outdoor coil, the integrated
heating capacity is 20,400 Btuh. (Select integrated
heating capacity value since deductions for outdoorcoil frost and defrosting have already been made.
No correction is required.)
The required heating capacity is 35,000 Btuh.
Therefore, 14,600 Btuh (35,000 – 20,400) additional electric heat is required.
Determine additional electric heat capacity in kW.

Below 80 F edb, subtract (corr factor x cfm)
from SHC.
Above 80 F edb, add (corr factor x cfm) to
SHC.

GENERAL NOTES FOR FAN PERFORMANCE TABLES
1. Extensive motor and electrical testing on these units ensures that
the full range of the motor can be utilized with confidence. Using
your fan motors up to the wattage ratings shown will not result in
nuisance tripping or premature motor failure. Unit warranty will not
be affected. For additional information on motor performance, refer
to Indoor-Fan Motor Performance table on page 110.
106
2. Values include losses for filters, unit casing, and wet coils. See
page 107 for accessory/FIOP static pressure information.
3. Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.
4. Interpolation is permissible. Do not extrapolate.

*Used to determine minimum disconnect per NEC.
†Heater capacity (kW) is based on heater voltage of 208 v, and 480 v.
If power istribution voltage to unit varies from rated heater voltage,
heater kw will vary accordingly.
**Fuse or HACR circuit breaker.
††Optional disconnect switch cannot be used.
***Units have 2 outdoor fan motors.
NOTES:
1. In compliance with NEC requirements for multimotor and combination load and equipment (refer to NEC Articles 430 and 440), the
overcurrent protective device for the unit shall be fuse or HACR
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 percent
of voltage imbalance.
112
452 + 464 + 455

= 457
Determine maximum deviation from average voltage.
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent of voltage imbalance.
7
% Voltage Imbalance = 100 x
457
= 1.53%
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.

Selection procedure (with 50HJQ016 example)
I Determine heating and cooling requirements
at design conditions.
Given:
Required Cooling Capacity (TC) . . . .164,000 Btuh
Sensible Heat Capacity (SHC) . . . . .120,000 Btuh
Required Heating Capacity . . . . . . .170,000 Btuh
Outdoor-Air Temperature (Cooling). . . . . . . . .95 F
Indoor Entering-Air Temperature
(Cooling) . . . . . . . . . . . . . . 80 F Edb/67 F Ewb
Outdoor Coil Entering-Air Temperature
(Heating) . . . . . . . . . . . . . . . . . . . . . . . . . . 0° F
Indoor Winter Design Temperature . . . . . . . . .70 F
Indoor-Air Quantity . . . . . . . . . . . . . . . 6000 Cfm
External Static Pressure (ESP . . . . . . . .1.30 in. wg
Electrical Characteristics (V-Ph-Hz) . . . . . 230-3-60
Economizer is specified.
Edb — Entering dry bulb
Ewb — Entering wet bulb
II Select unit based on required cooling capacity.
Enter Cooling Capacity table on page 130 at outdoor-entering temperature of 95 F, indoor air entering at 6000 cfm and 67 F ewb. The 50HJQ016 will
provide a total capacity (TC) of 180,800 Btuh, a
sensible heat capacity (SHC) of 136,400 Btuh and a
total unit kW of 15.88.
For indoor-air temperature other than 80 F edb, calculate sensible heat capacity correction, as required,
using the formula found in Note 3 following the
Cooling Capacities table on page 130.
NOTE: Unit ratings are gross capacities and do not
include the effect of indoor-fan motor heat. To calculate net capacities, see Step V.
III Select electric heat.
Enter the Integrated Heating Capacities table on
page 131 at 6000 cfm. At 70 F return indoor air
and 0° F air entering the outdoor coil, the integrated
heating capacity is 56,800 Btuh with a unit input
kW of 11.36.
The required heating capacity is 170,000 Btuh;
therefore, 113,200 Btuh (170,000 – 56,800) additional electric heat is necessary.
Determine the additional electric heat capacity in kW.
Enter the Electric Resistance Heater Data table at
230-3-60. The 34-kW heater satisfies the electric
heater requirements.
IV Determine fan speed and motor horsepower
requirements at design conditions.
Before entering Fan Performance table, calculate
the total static pressure required based on unit components. From the given and the Accessory/FIOP
Static Pressure table on page 134, find:
External static pressure
Economizer static pressure
Electric heat static pressure
1.30 in. wg
0.07 in. wg
0.09 in. wg
Total static pressure
1.46 in. wg
Enter the Fan Performance table on page 133. At
6000 cfm and 1.46 in. wg external static pressure,
the fan speed is 1214 and the bhp is 3.95 (interpolation required). The standard motor and alternate
high static drive are suitable.
V Determine net capacities.
Capacities are gross and do not include the effect of
indoor-fan motor (IFM) heat.
Determine net cooling capacity as follows:
Net capacity = Gross capacity – IFM heat
2545 Btuh
hp
= 180,800 – 3.95 bhp x
.85
= 180,800 – 11,827
= 168,973 Btuh
Net sensible capacity = 136,400 – 11,827
= 124,573 Btuh
Determine net heating capacity as follows:
Net capacity =
Gross capacity + IFM heat + Electric heat capacity
= 56,800 + (IFM kW x 3412) + (Elec. kW x 3412)
= 56,800 + 11,827 + (34 x 3412)
= 56,800 + 11,827 + 116,008
= 184,635 Btuh
50HJQ014,016
50TFQ004-012
113,200 Btuh
= 33.2 kW

NOTES:
1. Standard drive range is 817 to 1038 rpm. Alternate drive range is
1082 to 1303. Other rpms may require a field-supplied drive.
2. Maximum continuous bhp is 5.90 and maximum continuous watts
are 5180. Do not adjust motor rpm such that motor maximum bhp
and/or watts is exceeded at the maximum operating cfm.
GENERAL NOTES FOR FAN PERFORMANCE TABLES
1. Extensive motor and electrical testing on these units ensures that
the full range of the motor can be utilized with confidence. Using
your fan motors up to the wattage ratings shown will not result in
nuisance tripping or premature motor failure. Unit warranty will not
be affected. For additional information on motor performance, refer
to Indoor-Fan Motor Performance table on page 136.
2. Values include losses for filters, unit casing, and wet coils. See
page 134 for accessory/FIOP static pressure information.
3. Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.
4. Interpolation is permissible. Do not extrapolate.
