DESCRIPTION
The 558D/559F electric cooling rooftop units are designed to
deliver optimum performance and reliability in a commercial
rooftop unit. The 3 to 25 ton units are one-piece electric cooling
units that are prewired and precharged with R-22 at the factory,
making jobsite installation easy. Every unit is factory run-tested
prior to shipment to ensure reliable installation.
The 558D/559F units are designed to be field-convertible from
vertical supply/return to horizontal supply/return (180-300 units
require an accessoryhorizontal supply curb or adapter), making
them easily adaptable to a wide variety of new construction and
replacement applications. For vertical supply/return jobs, ductwork can be connected directly to the roof curb, allowing ductwork to be completed before unit is available for installation. All
units include easily replaceable internal filters.
The 558D/559F units are available with a range of accessory,
field-installed electric heating sizes and voltage options to meet
most job requirements. Low-voltage terminal blocks make wiring connections quick and simple.
All units are listed with either UL (Underwriters’ Laboratories)
or ETL(ETLTestingLaboratory) and withCSA(CanadianStandards Association), UL Canada, or ETL Canada.All units areARI
(Air-Conditioning & Refrigeration Institute) approved (except the
size 300, which is beyond the scope of the ARI Certification program) and comply with ASHRAE Standard 62 (American Society of Heating, Refrigeration, and Air Conditioning Engineers).

STANDARD FEATURES
EFFICIENT DESIGN means cooling energy savings. Standard
units have EERs (energy efficiency ratios) of up to 9.2, and
SEERs (Seasonal Energy Efficiency Ratios) of up to 10.0 (036060 units only).
THE FACTORY-ASSEMBLED PACKAGE (036-150 Units) is a
compact, fully self-contained electric cooling unit that is prewired, prepiped, and precharged for minimum installation
expense.
UNITS MAY BE CONVERTED TO HORIZONTAL DISCHARGE in the field. The units can be modified at the jobsite to
fit a variety of applications (180-300 units require an accessory
horizontal supply/return roof curb or a horizontal supply/return
adapter).
NEW TOOL-LESS FILTER ACCESS PANEL (036-150 Units)
provides easy access to filters. The new panel provides additional access space, permitting easy filter replacement in the
unit, even with an outdoor-air device mounted in a horizontal
position.
INTERNAL RETURN-AIR FILTERS are provided. Two-in.
throwaway filters are provided standard on all units, and can be
easily accessed through the tool-less access filter door.There is
no need to field-fabricate filter racks or install external filter
accessories.
COMPRESSOR PROTECTION is assured. The 036-150 units
have an internal pressure relief valve and line break (current
overload) protections, and the 180-300 units have high- and
low-pressure and freeze protection external to the compressor.
These protections prohibit operation under abnormal unit
conditions.
Form No. PDS 558D.36.5B
DUAL COMPRESSORS AND DUAL REFRIGERATION CIRCUITS (090-150 and 216-300 Units) are provided. Two com-
pressors, each on its own independent circuit, provide standby
reliability and high operating efficiency.
ADVANCED DESIGN of evaporator and condenser coils provides optimum heat transfer and cooling efficiency. Coils are
computer-designed with advanced heat transfer surfaces, and
are fabricated of copper tubing with aluminum fins.
COMMERCIAL STRENGTH BASE RAILS (full-perimeter on
036-150 units) with built-in rigging capability allow easy rigging
of unit.
WEATHER-RESISTANT CABINET is built for durability in any
climate. The cabinet is made of pre-painted, galvanized steel for
long life and high-quality appearance.
LOW-AMBIENT OPERATION is provided standard on most
units. The 036-150 units and the 240 units operate in cooling
down to 25 F as shipped from the factory. The 180 units operate
down to 40 F, the 216 units operate down to 35 F, and the
300 units operate down to 48 F. Low-ambient kits are not required for most applications.
HERMETICALLY-SEALED COMPRESSORS on the 036-150
units prevent contamination to help promote longer life and dependable operation. The 180-300 units have semi-hermetic
compressors.
COMPRESSOR VIBRATION ISOLATION MOUNTING on all
units eliminates noise-causing vibration transmission into the
conditioned space.
CRANKCASE HEATERS on the 180-300 units keep the oil free
of refrigerant during the off cycle for added compressor life and
reliability.Crankcase heaters are not necessary on the 036-150
units due to high-side crankcase design (072,150 units) and low
refrigerant charge levels (036-150 units).
POWER AND CONTROL CONNECTIONS are made on the
same side of the unit to simplify installation.
STANDARDWARRANTIESinclude 1 year on parts, with an additional 4 years on compressors (036-180 units). Additional extended warranties are also available.
3 TO 6 TON UNITS WEIGH LESS THAN 500 LB as standard
from the factory. This can eliminate the need for structural engineering approval on replacement jobs.
BELT-DRIVEN EVAPORATOR-FAN MOTORS are standard on
all 6 to 25 ton units, allowing adjustment of the available static
pressure to meet the job requirements of even the most demanding applications. Belt-driven evaporator-fan motors are
available as a factory-installed option on the 3 to 5 ton units.
• To reduce energy usage. Use whenever the number of hours
of operation at below 55 F is significant.
• The damper may be used on either vertical or horizontal
applications.
Parablade Economizer (036-150 Units) — The unique design
of the Parablade economizer saves energy while providing economical and reliable cooling. The new design uses a parallelopposed blade damper to permit outdoor ventilation air to enter
the unit any time the evaporator fan is running. The economizer
will permit cooling using 100% outdoor air whenever outdoor air
alone will provide adequate cooling. If the economizer alone
cannot provide enough cooling, then simultaneous economizer
and compressor operations will provide the most economical
operation. The economizer also has built-in spring return for reliable close-on-power loss. The Parablade design incorporates
standard enthalpy controls.
SUGGESTED USE:
• To allow a fixed percentage of outdoor air on vertical applications any time the evaporator fan is on, or to operate in economizer mode if outdoor air can provide cooling, but closes
when the evaporator fan is off to prevent cold backdrafts and
wasted energy.
• To reduce energy usage. Use whenever the number of hours
of operation at below 55 F is significant.
NOTE: Indoor-air quality (IAQ) restrictions require enthalpy controls to help regulate humidity in the occupied space.
25% and 50% Manual Outdoor-Air Damper — Package consists of a damper which can be set at 25% or 50% (036-150)
outdoor air. The package includes a rainhood and birdscreen.
SUGGESTED USE:
• Toallow a fixed percentage of outdoor air for ventilation under
all conditions.
• The damper may be used on either vertical or horizontal
applications.
NOTE: The 25% manual outdoor-air damper will be factory
installed whenever the factory-installed economizer is not
chosen on the 180-300 units.
Alternate Evaporator-Fan Motors (036-060,120,150 Units)
and Drives (036-060,090,120,150 Units) — Alternate motors
and/or drives allow operation of the evaporator fan at conditions
outside the range of the standard factory motor and drive
combination.
SUGGESTED USE:
• When higher static/airflow is required to meet job conditions.
FACTORY-INSTALLED OPTIONS
DESCRIPTION AND USAGE
Durablade (036-150) and Standard Integrated (180-300)
Economizers — The economizer will allow a fixed percentage
(between 0 and 100%) outdoor ventilation air into the unit any
time the evaporator fan is running. A dry-bulb thermostat placed
outdoors will bring in up to 100% outdoor air whenever the temperature of the outdoor air alone will adequately provide cooling.
If the economizer alone cannot provide enough cooling, then simultaneous economizer and compressor operation will provide
the most economical operation.
SUGGESTED USE:
• Toallow a fixed percentage of outdoor air any time the evaporator fan is on, or operates in economizer mode if outdoor air
can provide cooling, but closes when the evaporator fan is off
to prevent cold backdrafts and wasted energy.

SELECTION PROCEDURE (With 559F180 Example)
I Determine cooling and heating requirements at design
conditions.
Given:
Cooling Capacity Required (TC) .........177,000 Btuh
Sensible Heat Capacity (SHC) ..........127,000 Btuh
Condenser Entering-Air
Temperature..................95FEdb/78 F Ewb
Indoor-Air Temperature ...........80FEdb/67 F Ewb
Evaporator Air Quantity ..................6,000 cfm
External Static Pressure .................0.66 in. wg
Heating Capacity ......................76,000 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 Gross Cooling Capacities table on page 22 for
559F180 at condenser entering dry bulb temperature
95 F, air entering evaporator at 6000 cfm, 80 F edb and
67 F ewb. The 559F180 unit will provide a total cooling capacity of 188,000 Btuh, a sensible heating capacity of
136,000 Btuh and a total unit kW of 17.8 kW. 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.
NOTE: Unit ratings are gross capacities and do not include
the effect of evaporator-fan motor heat. To calculate net
capacities, see Step V.
III Select electric heat.
Heating load required is 76,000 Btuh.
76,000 Btuh
3,412 Btu/kW
Enter the Electric Resistance Heater Data table for the
559F180 on page 64 at 230-3-60. The 34 kW electric
heater most closely satisfies the heat required.
= kW of heat required
= 22.3 kW
IV Determine fan speed and motor horsepower require-
ments at design conditions.
Enter Accessory/FIOP Static Pressure Drop table on
page 47 at selected unit size and heater kW.
Find that at given air quantity (6000 cfm), pressure loss is
.09 in. wg.
Before entering the Air Delivery tables, calculate the total
static pressure required based on unit components. From
the given and the Accessory/FIOP Pressure table
(page 47) find:
External static pressure 0.66 in. wg
34 kW Heater static pressure 0.09 in. wg
Total static pressure 0.75 in. wg
Enter Air Delivery table for unit 559F180 on page 42. Interpolate to see that at 6000 cfm and 0.75 in. wg external
static pressure, the fan speed is 1184 rpm, the watts are
2631, and the bhp is 2.96. The standard motor with a fieldsupplied 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 from the Air Delivery table (calculated in Section IV above).
IFM watts = 2631
Determine net cooling capacity using the following
formula:
Net capacity = Gross capacity − IFM heat
= 188,000 Btuh − 2631 watts (3.412 )
= 188,000 Btuh − 8977 Btuh
= 179,023 Btuh
Net sensible capacity = 136,000 Btuh − 8977 Btuh
= 127,023 Btuh
As a result of the given conditions, the 559F180 unit is the
correct selection.
