Each

558F300

Each unit contains a factory printout indicating tested
pressures, amperages, dates, and inspectors, providing certifi­cation of the unit’s status at the time of manufacture.

Units are equipped with valuable safety controls designed to
monitor and protect the unit for life. The standard safeties
include:

• low-pressure/loss-of-charge switch

• high-pressure switch

• freeze-protection thermostat

• internal compressor overload

• exclusive Cycle-LOC™ circuit board that provides compres­sor anti-cycling (except 558F036-150)

conformance with ASHRAE (American Society of Heating,
Refrigeration, and Air Conditioning Engineers) Standard 62 to
meet many Indoor-Air Quality (IAQ) specifications. The conden­sate drain pan offers both bottom and end drain capability to

exists, the Cycle-LOC circuit board locks out the compressors.
Cycle-LOC may be manually reset by simply switching the ther­mostat to OFF, and back to the Cooling or AUTO modes. No use
of the unit power disconnect switch is required.

INDOOR-AIR QUALITY (IAQ)

Bryant rooftop units utilize certain key features that assist in
improving the quality of the building air. Sloped condensate
pans eliminate possible biological growth in the rooftop unit. A
face-split indoor coil design (all 090-300 size units) proves
effective in additional moisture removal from the supply air.
Two-in. filters are standard in all rooftop units with an optional
filter status sensor available.

Another Optional Indoor-Air Quality (IAQ) Feature

Perfect Humidity™ dehumidification package (except 558F036-

150). This is a factory-installed option that provides increased
dehumidification by cooling the hot liquid refrigerant leaving the
condenser coil. The Perfect Humidity option consists of a sub­cooling coil located on the leaving-air side of the evaporator coil.
The location of this coil in the indoor airstream enhances the
latent capacity of the units by as much as 40%. Many buildings
suffer from humidity damage or poor indoor air quality due to
humid conditions. The improved latent capacity provided by the
Perfect Humidity option reduces the building’s humidity, elimi­nating potential property damage and making the space more
comfor table.

The Perfect Humidity option makes units ideal IAQ rooftops for
hot and humid regions. The operation of the Perfect Humidity
package can be controlled by a field-installed, wall-mounted
humidistat, or light commercial thermidistat. The circuit acti­vates only when needed (using the accessory humidistat) as
opposed to some dehumidification systems that operate contin­uously. The humidistat can be set for any humidity level
between 20% and 80% relative humidity.

SERVICEABILITY
Servicing a Rooftop Unit has Never Been Easier

new factory-installed Hinged Panel Option (except 558F036-

150). This option includes hinged access panels for the filter,
compressor, evaporator-fan motor, and control box areas.
These panels provide quick and simple access to the major
components by simply unlocking and swinging open the differ­ent panels. Each hinged access panel is permanently attached
to the rooftop unit, eliminating the problem of access panels
being dropped and creating a hole in the roof (potentially caus­ing a water leak). This type of damage could void any warranty
offered for a new roof.

Perfect Humidity™ DEHUMIDIFICATION PACKAGE

(036-150)

The Perfect Humidity dehumidification package is a factory-installed option that provides increased dehumidification by cooling the hot liquid refrig­erant leaving the condenser coil. The Perfect Humidity package consists of a subcooling coil located on the leaving-air side of the evaporator coil.
The location of this coil in the indoor airstream enhances the latent capacity of the units by as much as 40%. The Perfect Humidity package includes
the subcooling coil and low-pressure switches, and operation can be controlled by a field-installed, wall-mounted humidistat or thermidistat.

DURABLADE ECONOMIZER

BRYANT COMMERCIAL THERMOSTAT

Designed specifically for use with Bryant commercial systems, this
Bryant programmable thermostat features LED occupied/
unoccupied displays and setback mode which can override continu­ous fan operation.

ECONOMI$ER (036-150)

Exclusive Durablade economizer damper design saves energy while
providing economical and reliable cooling. A sliding plate on the face
of the economizer controls the amount of outdoor air entering the
system. When the sliding plate is closed, it provides a leakproof seal
which prevents ambient air from seeping in or conditioned air from
seeping out. It can be easily adjusted for 100% outdoor air or any
proportions of mixed air. Design includes standard dry-bulb control
and 30% barometric relief capability.

Factory-installed EconoMi$er utilizes a microprocessor-based con­trol, gear drive damper system, low pressure drop characteristics,
built-in spring return (for close upon power loss), and an integral
barometric damper.

EconoMi$er is available for vertical ductwork applications

CONTROLS

OPERATING SEQUENCE — SIZE 036-073 UNITS
Cooling, Units Without Economizer —

calls for cooling, terminals G and Y1 are energized. The indoor
(evaporator) fan contactor (IFC), and compressor contactor
no. 1 (C1) are energized and the indoor (evaporator) fan motor
(IFM), compressor no. 1, and condenser fan start. The outdoor
(condenser) fan motor (OFM) runs continuously while unit is
cooling.

Cooling, Units With EconoMi$er —

temperature (OAT) is above the ECON SP set point and the
room thermostat calls for Stage 1 cooling (R to G + Y1), the
indoor (evaporator) fan motor (IFM) is energized and the
EconoMi$er damper modulates to minimum position. The com­pressor contactor is energized to start the compressor and out­door (condenser) fan motor (OFM). 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.

Compressor has a 2-minute Minimum On, Minimum Off,

NOTE:

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 position of the EconoMi$er damper is main­tained at its current value.

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 position of the
EconoMi$er damper is maintained at its current value.

greater than 57 F, the EconoMi$er modulates open, allowing a
greater amount of outdoor air to enter the unit. If the SAT drops

Units With Perfect Humidity™ Dehumidification Package —

When thermostat calls for cooling, terminals G and Y1 and/or
Y2 and the compressor contactor C1 and/or C2 are energized.
The indoor (evaporator) fan motor (IFM), compressors, and out­door (condenser) fan motors (OFM) start. The OFMs run
continuously while the unit is in cooling. As shipped from the
factory, both Perfect Humidity dehumidification circuits are
always energized.

If Perfect Humidity circuit modulation is desired, a field-installed,
wall-mounted light-commercial thermidistat (with field-supplied
relay) is required. If the thermidistat is installed and calls for the
Perfect Humidity subcooler coil to operate, the relay switch
closes. This energizes the 3-way liquid line solenoid valve coils
(LLSV1 for circuit 1 and LLSV2 for circuit 2) of the Perfect
Humidity circuits, forcing the warm liquid refrigerant of the liquid
line to enter the subcooler coils.

As the warm liquid passes through the subcooler coils, it is
exposed to the cold supply airflow coming off the evaporator
coils and the liquid is further cooled to a temperature approach­ing the evaporator coil leaving-air temperature. The state of the
refrigerant leaving the subcooler coils is a highly subcooled
liquid refrigerant. The liquid then enters a thermostatic expan­sion valve (TXV) where the liquid is dropped to the evaporator
pressure. The TXVs can throttle the pressure drop of the liquid
refrigerant and maintain proper conditions at the compressor
suction valves over a wide range of operating conditions.
The liquid proceeds to the evaporator coils at a temperature
lower than normal cooling operation. This lower temperature is
what increases the latent and sensible capacity of the evapora­tor coils.

The 2-phase refrigerant passes through the evaporators and is
changed into a vapor. The air passing over the evaporator coils
will become colder than during normal operation as a result of
the colder refrigerant temperatures. However, as it passes over
the subcooler coils, the air will be warmed, decreasing the sen­sible capacity and reducing the sensible heat of the rooftop unit.

When the room thermostat calls for heat, the heat-

CONTROLS (cont)

As the refrigerant leaves the evaporator, the refrigerant passes
a subcooler control low-pressure switch (S-LPS1 for circuit 1 or
S-LPS2 for circuit 2) in the suction line. This low-pressure
switch will deactivate the Perfect Humidity™ package when the
suction pressure reaches 60 psig. The subcooler control low­pressure switch is an added safety device to protect against
evaporator coil freeze-up during low ambient operation. The
subcooler control low-pressure will only deactivate the 3-way
liquid line solenoid valve in the Perfect Humidity circuit. The
compressors will continue to run as long as there is a call for
cooling, regardless of the position of the subcooler control low­pressure switch. The 3-way solenoid valve and the Perfect
Humidity package will be reactivated only when the call for cool­ing has been satisfied, the subcooler control low-pressure
switch has closed above 80 psig, and a new call for cooling
exists. The crankcase heaters on the scroll compressors
provide additional protection for the compressors due to the
additional refrigerant charge in the subcooler.

When the thermidistat is satisfied, the relay internal switch
opens, cutting power to and deenergizing the LLSVs. The
refrigerant is routed back through the evaporators and the
subcooler coils are removed from the refrigerant loops. When
the thermostat is satisfied, C1 and C2 are deenergized and
the compressors, IFM, and OFMs shut off. If the thermostat
fan selector switch is in the ON position, the IFM will run
continuously.

INDOOR-AIR QUALITY —

Humidity is a major factor in
the growth and propagation of mold and mildew in a
building. The mold and mildew can spread quickly and
grow in carpets and ductwork and on walls, and often
causes cases of sick building syndrome. This syndrome
can lead to employee absenteeism due to illness, lower
worker productivity, and increased health care costs. The
American Society of Heating, Refrigeration, and Air Con­ditioning Engineers (ASHRAE) recommends that relative
humidity levels in buildings be maintained below 70%.

COMFORT LEVELS —

High humidity levels cause the
occupied space to become uncomfortable, because
humidity interferes with the body’s natural cooling pro-
cess (evaporation at the skin surface).

NOTE:

1. Do not drill in this area, damage to basepan may result in
water leak.

e.

EQUIPMENT INEFFICIENCY —

inefficient operation of refrigerators and freezers.

f.

INCREASED ENERGY COSTS —

humidity levels and less comfortable conditions, thermo­stat set points are lowered to force the HVAC (heating,
ventilation, and air conditioning) equipment to run longer
and work harder to lower the humidity levels. Also, in an
attempt to control humidity, system designers typically
oversize HVAC equipment and add reheat capability to
get the desired latent capacity. This results in higher ini­tial equipment costs, as well as increased energy
expenses throughout the life of the unit.

Applications

There are many different rooftop unit applications that are
susceptible to problems caused by high humidity levels.
Some common applications include:

a.

RESTAURANTS —

have many humidity-producing activities, such as dish
washing and cooking.

b.

SUPERMARKETS —

ciency in operation of refrigeration and freezer systems.

c.

MUSEUMS AND LIBRARIES —

books and artwork.

d.

GYMNASIUMS, LOCKER ROOMS, AND HEALTH
CLUBS —

e.

HOT AND HUMID CLIMATES —

United States is a good example of this application. The
Perfect Humidity dehumidification package becomes
particularly useful when increased amounts of the hot

DESIGN EFFECTS —

the Perfect Humidity dehumidification package, refer to the
pressure enthalpy curve, and analyze the Perfect Humidity
package effects on the refrigerant in the rooftop unit. The
pressure enthalpy curve shows the refrigerant cycle for a

rooftop unit.
Standard Unit Refrigerant Cycle
At point no. 1 in the pressure enthalpy curve, vapor leaving the

compressor at a high pressure and a high temperature enters
the condenser. The condenser removes heat from the refriger­ant, lowers its temperature, and changes it to a liquid. At point
no. 2, the liquid leaves the condenser and enters a fixed expan­sion device that lowers the pressure of the refrigerant. At point
no. 3, the liquid enters the evaporator coil, where the refrigerant
increases in temperature and changes back to a vapor. At point
no. 4, the vapor leaves the evaporator and reenters the
compressor.

Refrigerant Cycle Using Perfect Humidity™ Dehumidification
Package

When a subcooler coil is added to the rooftop unit, the refriger­ant is affected in such a way that the unit latent capacity is
increased. The refrigerant cycle follows the same path from
point no. 1 to point no. 2 as the standard refrigerant cycle with­out a subcooler (see the pressure enthalpy curve). However, at
point no. 2, the liquid refrigerant enters the subcooler coil where
the temperature is lowered further. At point no. 2A, this sub­cooled liquid enters the TXV, which drops the pressure of the
liquid. At point no. 2B, the liquid enters the fixed orifice metering
device. The refrigerant leaves this device as a saturated vapor
and enters the evaporator at point no. 2C. The improved refrig­eration effect can now be seen between point no. 2C and point
no. 3. The increase in the total refrigeration effect is the addi­tional enthalpy gained from point no. 2C to point no. 3. However,
the subcooler coil rejects this added refrigeration effect to the
air downstream of the evaporator coil, thus maximizing the over­all latent effect. This improved latent effect is a direct result of
the addition of the Perfect Humidity subcooler coil to the refrig­erant cycle.

Latent Capacity Effects
Refer to the psychrometric chart to see how the sensible heat

factor decreases when the optional Perfect Humidity dehumidifi­cation package is installed. This chart contains data for the
5-ton unit operation, both with and without the Perfect Humidity
package, at 1750 cfm. Point no. 1 on the chart represents the
return-air dry bulb (80 F) and wet bulb (67 F) conditions. Point
no. 2 represents the supply-air conditions for a standard rooftop
unit without the Perfect Humidity dehumidification package.
Point no. 3 represents the supply-air conditions for a rooftop unit
with the Perfect Humidity package. By connecting point no. 1
and point no. 2 on the chart and finding the intersection on the
sensible heat factor scale, the sensible heat factor is 0.73. Con­nect point no. 1 and point no. 3, and see that the sensible heat
factor is 0.58. This is a 17.5% increase in latent capacity for the
given conditions. This increase in latent capacity allows the
rooftop units to remove more moisture from the conditioned
space; thus lowering the humidity levels.

Dehumidification Effects
Further evidence of dehumidification can be seen by analyzing

the pounds of water per pound of dry air found in the supply air.
At point no. 2 in the psychrometric chart, there are 65 grains
(0.0092 lb) of moisture per pound of dry air. At point no. 3, there
are 58 grains (0.0083 lb) of moisture per pound of dry air. This
is a 12.1% decrease in the amount of water in the supply air.

PERFECT HUMIDITY DEHUMIDIFICATION PACKAGE
OPERATING PERFORMANCE —

midification package operation does not affect the electrical
data. The electrical data remains the same either with or
without the Perfect Humidity package.

The operating and shipping weights will be slightly
increased with the addition of the Perfect Humidity sub­cooler. See the Physical Data table for added base unit
weight with this option.

Refer to cooling performance data, both with and without
the Perfect Humidity dehumidification package. Note the
greatly improved latent capacity with the Perfect Humidity

15. PERFECT HUMIDITY DEHUMIDIFICATION PACKAGE
FEATURES AND BENEFITS

• The Perfect Humidity dehumidification package can improve

the humidity control of your rooftop equipment by up to 40%.
This greatly reduces the risk of sick building syndrome by
reducing biological growth in both ductwork and the rest of
the building.

• The Perfect Humidity dehumidification package improves

comfort levels in the building by better controlling the humid­ity. This improved comfort level allows building tenants to
raise the cooling set point on the thermostats for accumu­lated energy savings.

• Better humidity control lowers the risk of humidity-induced

property damage.

• The Perfect Humidity dehumidification package permits build-

ing refrigerators and freezers to operate more efficiently due
to lower relative humidity levels. This is the perfect solution for
supermarket applications.

• The Perfect Humidity subcooling circuit can be operated by a

humidity sensor. If the sensor is used, the Perfect Humidity
circuit will then only operate when needed. If the humidity lev­els in the occupied space are acceptable (such as in the
spring and fall seasons), the Perfect Humidity circuit will not
operate. The rooftop unit is then able to operate to its full sen­sible potential, which provides more efficient performance
and energy savings.

• At lower outdoor temperatures, rooftop units with dehumidifi-

cation devices are subject to low suction pressure conditions.
The Perfect Humidity dehumidification package contains a
low-pressure switch that deactivates the Perfect Humidity
dehumidification package under low suction pressure condi­tions without deactivating the compressors.

• Improved humidity control allows increased outdoor-air venti­lation in hot and humid geographical areas. Humidity control
also helps to improve the indoor-air quality of the building.

• The Perfect Humidity dehumidification package is factory
installed. There are no additional field installation costs.
There is also no need to purchase a roof curb from another
manufacturer, as standard Bryant roof curbs will accommo­date the rooftop units which have the Perfect Humidity dehu­midification package option installed.

• The Perfect Humidity dehumidification package is engineered
and manufactured by Bryant for Bryant rooftop units. All
application support, service, and warranty issues can there­fore be handled through one company.

• The slightly lower sensible capacities obtained when using
the Perfect Humidity dehumidification package allow the unit
to operate for an extended period of time. The more the unit
operates, the more air is exposed to the subcooling coil. This
rooftop unit increased latent capacity results in lower relative
humidity levels in the occupied space.

• It is no longer necessary to oversize equipment and add
reheat devices to properly dehumidify your building. In a typi­cal scenario, a building owner may need 39,000 Btuh of sen­sible capacity and 23,000 Btuh of latent capacity (62,000 total
Btuh). To accomplish this without the Perfect Humidity dehu­midification package, a 7

1

/2-ton unit with a reheat device
would be necessary to attain the higher latent capacity
required. This results in a large up-front expense to oversize
the equipment from a standard 5-ton to a 7

1

/2-ton unit.

The building owner can now purchase a 5-ton unit with the
Perfect Humidity dehumidification package for a small addi­tional up-front charge, and no reheat device will be necessary
to satisfy the cooling requirements. This reduces both installa­tion costs and operating costs throughout the life of the
product.

Evaporator Entering-Air

Temperature . . . . . . . . . . . . . . . . . . .80 F Edb/67 F Ewb

Evaporator Air Quantity . . . . . . . . . . . . . . . . . . . .1600 cfm

External Static Pressure . . . . . . . . . . . . . . . . . 0.75 in. wg

Heating Capacity . . . . . . . . . . . . . . . . . . . . . . 50,000 Btuh

Power Supply (V-Ph-Hz) . . . . . . . . . . . . . . . . . . .230-3-60

Edb — Entering dry bulb
Ewb — Entering wet bulb

II SELECT UNIT BASED ON REQUIRED COOLING

CAPACITY.

Enter cooling capacity table for 558F048 on page 36 at
condenser entering dry bulb temperature 95 F, air entering
evaporator at 1600 cfm, 80 F edb and 67 F ewb. The
558F048 unit will provide a total cooling capacity
of 50,500 Btuh, and a sensible heating capacity of
35,600 Btuh. For evaporator-air temperatures other than
80 F edb, calculate sensible heat capacity correction as
required using the formula in the notes following the Cool­ing Capacities tables.

Unit ratings are gross capacities and do not

NOTE:

include the effect of evaporator-fan motor heat. To calcu­late net capacities, see Step V.

III SELECT ELECTRIC HEAT.

Heating load required is 50,000 Btuh.

50,000 Btuh

3.412 Btu/W

Enter the Electric Heating Capacities table on page 64 for
the 558F048 at 230-3-60. The 16.0 kW electric heater
most closely satisfies the heat required.

To calculate kW at 230 v, use the multiplication factors
table on page 64.

16.0 x .918 = 14.7 kW

16.0 x .918 x 3.413 = 50,115 Btuh gross capacity

= 14,654 Watts of heat required

= 14.7 kW

IV DETERMINE FAN SPEED AND MOTOR HORSEPOWER

REQUIREMENTS AT DESIGN CONDITIONS.

Enter Accessory/FIOP Static Pressure table on page 61 at
selected unit size and heater kW.

Find that at given air quantity (1600 cfm), pressure loss is

0.09 in. wg.
Before entering the Fan Performance tables, calculate the

total static pressure required based on unit components.
From the given find:

External static pressure 0.75 in. wg
16 kW Heater static pressure 0.09 in. wg

Total static pressure 0.84 in. wg

Enter Fan Performance table for the alternate motor verti­cal discharge unit 558F048 on page 41. At 1600 cfm and

0.84 in. wg external static pressure, the fan speed is
1038 rpm and the watts are 877. (Interpolation is neces­sary.) The alternate motor and drive is suitable.

V DETERMINE NET COOLING CAPACITY.

Cooling capacities are gross capacities and do not include
indoor (evaporator) fan motor (IFM) heat. Use the watts
input power to the motor calculated in “Section IV” above.

IFM watts = 877
Determine net cooling capacity using the following

formula:

Net capacity = Gross capacity – IFM heat

= 50,500 Btuh – 877 Watts (3.413

= 50,500 Btuh – 2992 Btuh
= 47,508 Btuh

Net sensible capacity = 35,600 Btuh – 2992 Btuh

= 32,608 Btuh

As demonstrated above, the 558F048 with the 16.0 kW
electric heater and an alternate motor meets the cooling
capacity, sensible heating capacity, and heating capacity
requirements.

GENERAL FAN PERFORMANCE NOTES

NOTES:

1. Values include losses for filters, unit casing, and wet coils. See
page 61 for accessory/factory-installed option static pressure
information.

2. 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. See Evaporator-Fan Motor Performance table on
page 63 for additional information.

3. Use of a field-supplied motor may affect wire sizing. Contact your
Bryant representative for details.

4. Interpolation is permissible. Do not extrapolate.

AC = 455 v

Average Voltage =

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.

SELECTION PROCEDURE (With 551B048 Example)

I DETERMINE COOLING AND HEATING REQUIRE-

MENTS AT DESIGN CONDITIONS.

Given:

Required Cooling Capacity (TC). . . . . . . . . . . 44,000 Btuh

Sensible Heat Capacity (SHC) . . . . . . . . . . . . 32,000 Btuh

Required Heating Capacity. . . . . . . . . . . . . . . 50,000 Btuh

Condenser Entering-Air Temperature . . . . . . . . . . . . .95 F

Evaporator Entering-Air Temperature . . . . . . . . . 82 F edb,

Evaporator Air Quantity . . . . . . . . . . . . . . . . . . . 1600 cfm

External Static Pressure (ESP) . . . . . . . . . . . . 0.75 in. wg

Electrical Characteristics (V-Ph-Hz) . . . . . . . . . . 230-3-60

II SELECT UNIT BASED ON REQUIRED COOLING

CAPACITY.

551B036-150
0TFQ004-012

Enter the Cooling Capacities table on page 79 at con­denser entering temperature of 95 F, evaporator-air enter­ing at 1600 cfm and 80 F db and 67 F wb. The 551B048
unit will provide cooling capacity of 48,900 Btuh and a
sensible heat capacity of 34,700 Btuh. For evaporator-air
temperature other than 80 F edb, calculate sensible heat
capacity correction, as required, using the formula found in
the notes following the Cooling Capacities tables.

For this example:
Correction factor = 1.1 x (1 – .21) x (82 – 80)

= 1.738

Multiply the correction factor by 1600 cfm (a total of 2781).
From the Gross Cooling Capacities tables find that the
sensible heat capacity at 80 F is 34.7 MBtuh (equivalent to
34,700 Btuh). Add 34,700 and 2781 to get the corrected
sensible heat capacity of 37.48 MBtuh (37,481 Btuh).

Unit ratings are gross capacities and do not

NOTE:

include the effect of evaporator-fan motor heat. To calcu­late net capacities, see Step V.

III SELECT ELECTRIC HEAT.

Heating load required is 50,000 Btuh.

50,000

3.413 Btuh/kW

Enter the electric Heating Capacities table on page 97 for
551B048 at 208/230 (3 phase). The accessory 16.0 kW
heater at 240 v most closely satisfies the heating required.
To calculate kW at 230 v, use the Multiplication Factors
table on page 97.

16.0 x .92 = 14.7 kW

16.0 x .92 x 3413 = 50,240 Btuh gross capacity

= 14.6 kW of heat required

67 F ewb

IV DETERMINE FAN SPEED AND POWER REQUIRE-

MENTS AT DESIGN CONDITIONS.

Before entering the Fan Performance tables, calculate the
total static pressure required based on unit components.
From the given and the Pressure Drop tables on page 94,
find:

External static pressure .75 in. wg
Electric heat .09 in. wg

Total static pressure .84 in. wg

Enter the Fan Performance table for 551B048 vertical dis­charge unit on page 85. At 1600 cfm, the standard motor
will deliver 1.20 in. wg static pressure and 1.15 Bhp. This
will adequately handle the job requirements.

V DETERMINE NET CAPACITIES.

Capacities are gross and do not include the effect of
indoor (evaporator) fan motor (IFM) heat. To determine
input power to the motor, convert bhp to watts using the
Evaporator-Fan Motor Efficiency table on page 94.

IFM Watts =

Determine net cooling capacity as follows:
Net capacity = gross capacity – IFM heat

Net sensible capacity = 37,481 Btuh – 3904 Btuh

Determine net heating capacity as follows:

Net capacity = gross capacity + IFM heat

Bhp x 746 Watts/Bhp

*Used to determine minimum disconnect per NEC.

†Heater capacity (kW) is based on heater voltage of 208 v, 240 v, 480 v or 575 v.

If power distribution voltage to unit varies form rated heater voltage, heater kW
will vary accordingly.

**Fuse or HACR circuit breaker per NEC.

††Units have 2 condenser-fan motors.

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%.

Maximum deviation is 7 v.
Determine percent of voltage imbalance.

% Voltage Imbalance = 100 x

This amount of phase imbalance is satisfactory as it is below the maximum
allowable 2%.

IMPORTANT:

your local electric utility company immediately.

3. Non-fused disconnect switch cannot be used when rooftop unit electrical
ratings exceed 80 amps.

4. 575-v units have UL, Canada approval only. Electric heaters are not avail­able for 036-072, 575-v units.
