Low Ambient - An integrated low-ambient control
allows all units to operate in the cooling mode down
to 0ºF outdoor ambient without additional assis-
tance. Optionally, the control board can be pro-
grammed to lockout the compressors when the
outdoor air temperature is low or when free cooling
is available.
FEATURES
All models are available with a wide variety of factory-
mounted options such as stainless steel heat exchangers,
phase monitor, dirty filter switch, and coil guard to make them
suitable for almost every application.
All units are self-contained and assembled on full perimeter
base rails with holes in the four corners for overhead rigging.
Every unit is completely piped, wired, charged and tested at
the factory to simplify the field installation and to provide
years of dependable operation.
Anti-Short Cycle Protection - To aid compressor
life, an anti-short cycle delay is incorporated into the
standard controls. Compressor reliability is further
ensured by programmable minimum run times. For
testing, the anti short cycle delay can be temporarily
overridden with the push of a button.
All models (including those with an economizer) are suitable
for either bottom or horizontal duct connections. Models with
factory installed power exhaust are suitable for bottom
duct connections only. For bottom duct, you remove the
sheet metal panels from the supply and return air openings
through the base of the unit. For horizontal duct, you replace
the supply and return air panels on the rear of the unit with a
side duct flange accessory.
•
•
Lead-Lag - An integrated Lead-Lag option allows
equal run time hours on all compressors, thereby
extending the life of all compressors. This option is
selectable on the unit control board.
Fan Delays - Fan on and fan off delays are fully pro-
grammable. Furthermore, the heating and cooling
fan delay times are independent of one another. All
units are programmed with default values based
upon their configuration of cooling and heat.
All models are available with these “factory mounted” outdoor
air damper options:
•
Single enthalpy economizer with or without power
exhaust
•
•
•
Safety Monitoring - The control board monitors the
high and low-pressure switches, the freezestats, the
gas valve, if applicable, and the temperature limit
switch on gas and electric heat units. The unit con-
trol board will alarm on ignition failures, compressor
lockouts and repeated limit switch trips.
•
•
•
BAS-ready economizer with or without power exhaust
Motorized outdoor air damper
Barometric Relief Damper
A fixed outdoor air intake assembly will be shipped in the
return air compartment of all units ordered without an econo-
mizer or motorized outdoor air damper option. The assembly
includes a rain hood with a damper that can be set for 10, 15
or 25% outdoor air. With bottom duct connections, the intake
damper assembly should be mounted over the opening in the
return air panel. With horizontal ductwork, it should be
mounted on the return air duct.
Nuisance Trip Protection and Strikes - To prevent
nuisance trouble calls, the control board uses a
“three times, you’re out” philosophy. The high and
low-pressure switches and the freezestats must trip
three times within two hours before the unit control
board will lock out the associated compressor.
On Board Diagnostics - Each alarm will energize a
trouble light on the thermostat, if so equipped, and
flash an alarm code on the control board LED. Each
high and low-pressure switch alarm as well as each
freezestat alarm has its own flash code. The control
board saves the five most recent alarms in memory,
and these alarms can be reviewed at any time.
Alarms and programmed values are retained
through the loss of power.
All supply air blowers are equipped with a belt drive that can
be adjusted to meet the exact requirements of the job. A high
static drive option is available for applications with a higher
CFM and/or static pressure requirement. A variable air vol-
ume (VAV) option using a variable frequency drive is available
for applications requiring a constant supply duct pressure. A
differential pressure transducer is used to monitor supply duct
static pressure and return a speed reference signal to the VFD
to control the output of the indoor blower motor.
All units have long lasting powder paint cabinets with 1000
hour salt spray test approval under ASTM-B117 procedures.
All compressors include scroll compressors and internal pres-
sure relief. Every refrigerant circuit includes an expansion
valve, a liquid line filter-drier, a discharge line high pressure
switch and a suction line with a freezestat and low pressure/
loss of charge switch to protect all system components. A hot
gas bypass option, consisting of an adjustable compressor
discharge bypass valve, is available for low cooling load
applications.
All models are CSA approved.
•
Warranty - All models include a one-year limited parts
warranty on the complete unit. Compressors and electric
heater elements carry a five-year warranty. Gas heat
exchangers carry a 10-year parts warranty.
•
Gas Heat Operation - All gas heat units are built with
two heating sections for two equal stages of capacity
control. Each section includes a durable heat exchanger
•
S implicity® Controls - S implicity® control boards have
standardized a number of features previously available
only as options or by utilizing additional controls.

Electric Heat Operation - All electric heat models (fac-
tory installed only) are wired for a single power source
and include a bank of nickel chromium elements
mounted at the discharge of the supply air blower to pro-
vide a high velocity and uniform distribution of air across
the heating elements. Every element is fully protected
against excessive current and temperature by fuses and
two thermal limit switches.
Actuator requires 2-10 VDC input from an external
source, such as a field-installed or factory-installed BAS
controller. BAS-ready actuators have an adjustable auxil-
iary end-switch for optional power exhaust control.
For units with optional VAV or Simplicity® Intelli-Com-
fort™ control, a factory-installed, dry bulb sensor deter-
mines if outdoor air temperature is low enough to provide
free-cooling operation. (Field-installed humidity sensors
for either outdoor air or outdoor & return air streams are
available for single enthalpy and differential enthalpy
configurations, respectively).
The power supply wiring can be routed into the control
box through a threaded pipe connection in the base pan
of the unit or through a knockout in the wiring panel on
the front of the unit.

pressure in the supply duct. A pressure transducer and
VAV control board are mounted inside the control box.
The drive comes completely wired and pre-programmed
from the factory.
DOUBLE WALL CONSTRUCTION - Optional double
wall construction is available to provide smooth inner
surfaces for easy and effective cleaning to reduce risk of
dirt and bacterial accumulation. Fiberglass insulation is
sandwiched between heavy gauge steel sheets to form a
durable, rigid casing to withstand higher working pres-
sures and impact forces. The heavy-duty construction
provides excellent acoustic and thermal insulation and
eliminates erosion of insulation material and contamina-
tion of the air stream.
An optional, factory-installed manual bypass switch
available with factory-installed VFD can be found in the
Blower Motor Access compartment. The switch can be
used to either route power to the VFD for modulating
control of the blower motor, to bypass the drive and oper-
ate the motor at full speed, or to power the drive (and not
the motor) for diagnostic purposes.

dBA values provided are to be used for reference only. Calculation of dBA values cover matters of system design and the fan
manufacture has no way of knowing the details of each system. This constitutes and expectation to any specification or guarantee
requiring a dBA value or sound data in any other form than sound power level ratings.

For units with VFD and electric or gas heat, the
speed of the indoor blower motor continues to
be controlled by duct static pressure via the
VAV control board.
If there are VAV boxes present in the duct sys-
tem, the boxes must be driven to the full-open
position using a customer-supplied power
source to assure adequate airflow across elec-
tric heating elements or gas heat exchanger
tubes.

The capacities are gross ratings. For net capacity, deduct air blower motor, MBh = 3.415 x kW. Refer to the appropriate Blower
Performance table for the kW of the supply air blower motor.
These ratings include the condenser fan motors (total 1 kW) and the compressor motors but not the supply air blower motor.

order to use the indoor blower tables for high altitude applica-
tions, certain corrections are necessary.
CFM, STATIC PRESSURE, AND POWER - ALTI-
TUDE AND TEMPERATURE CORRECTIONS
A centrifugal fan is a "constant volume" device. This means
that, if the rpm remains constant, the CFM delivered is the
same regardless of the density of the air. However, since the
air at high altitude is less dense, less static pressure will be
generated and less power will be required than a similar
application at sea level. Air density correction factors are
The information below should be used to assist in application
of product when being applied at altitudes at or exceeding
1000 feet above sea level.
The air flow rates listed in the standard blower performance
tables are based on standard air at sea level. As the altitude
or temperature increases, the density of air decreases. In

The examples below will assist in determining the airflow per-
formance of the product at altitude.
blower tables to select the blower speed and the BHP
requirement.
Example 1: What are the corrected CFM, static pressure,
and BHP at an elevation of 5,000 ft. if the blower performance
data is 6,000 CFM, 1.5 IWC and 4.0 BHP?
Solution: As in the example above, no temperature informa-
tion is given so 70°F is assumed.
The 1.5" static pressure given is at an elevation of 5,000 ft.
The first step is to convert this static pressure to equivalent
sea level conditions.
Solution: At an elevation of 5,000 ft the indoor blower will still
deliver 6,000 CFM if the rpm is unchanged. However, Table
8 must be used to determine the static pressure and BHP.
Since no temperature data is given, we will assume an air
temperature of 70°F. Table 8 shows the correction factor to
be 0.832.
Sea level static pressure = 1.5 / .832 = 1.80"
Enter the blower table at 6000 sCFM and static pressure of
1.8". The rpm listed will be the same rpm needed at 5,000 ft.
Corrected static pressure = 1.5 x 0.832 = 1.248 IWC
Corrected BHP = 4.0 x 0.832 = 3.328
Suppose that the corresponding BHP listed in the table is 3.2.
This value must be corrected for elevation.
Example 2: A system, located at 5,000 feet of elevation, is to
BHP at 5,000 ft = 3.2 x .832 = 2.66
deliver 6,000 CFM at a static pressure of 1.5". Use the unit

York's Sunline Magnum™ units are convertible single pack-
age units. All models have dual independent refrigerant cir-
cuits for efficient part load operation and maximum comfort
control. Although the units are primarily designed for curb
mounting on a roof, they can also be slab-mounted at ground
level or set on steel beams above a finished roof. Cooling
only, cooling with gas heat and cooling with electric heat
models are available with a wide variety of factory-mounted
options and field-installed accessories to make them suitable
for almost every application. All units are self-contained and
assembled on full perimeter base rails with holes in the four
corners for overhead rigging. Every unit is completely piped,
wired, charged and tested at the factory to simplify the field
installation and to provide years of dependable operation. All
models (including those with an economizer) are suitable for
either bottom or horizontal duct connections. Models with
power exhaust are suitable for bottom duct connections only.
For bottom duct, remove the sheet metal panels from the
supply and return air openings through the base of the unit.
For horizontal duct, replace the supply and return air panels
on the rear of the unit with a side duct flange accessory. All
supply air blowers are equipped with a belt drive that can be
adjusted to meet the exact requirements of the job.

ters shall be provided. Simultaneous economizer/com-
pressor operation is also possible. Dampers shall fully
close on power loss.
Nickel chromium electric heating elements shall be provided
as required by the application with 1 or 2 stage control, as
required, from 13.5 KW to 72 KW capacities. The heating
section shall have a primary limit control(s) and automatic

BAS-READY ECONOMIZER - Outdoor and return air
dampers that are interlocked and positioned by a fully-
modulating, spring return damper actuator. The maxi-
mum leakage rate for the outdoor air intake dampers
shall not exceed 2% when dampers are fully closed and
operating against a pressure differential of 0.5 IWG.
For units with optional VAV or Simplicity® Intelli-Com-
fort™ control, free-cooling shall be available while the
outdoor dry bulb temperature (OAT) remains below a
programmable set-point of the controller. Field-installed
humidity sensors for either outdoor air or outdoor &
return air streams are available to provide free-cooling
based on single-enthalpy or dual-enthalpy configura-
tions, respectively. If free-cooling is available, a call for
cooling shall modulate the economizer in order to main-
tain a supply air temperature (SAT) programmable set-
point. With the use of a field-installed indoor air quality
sensor, the controller shall provide Demand Ventilation
by modulating the economizer dampers to allow more
UNIT OPERATING CHARACTERISTICS
Unit shall be capable of starting and running at 125° F
outdoor temperature, exceeding maximum load criteria of
ARI Standard 340/360. The compressor, with standard
controls, shall be capable of operation down to 25° F outdoor
temperature. Accessory low ambient kit shall be available for
operation to 0° F. Unit shall be provided with fan time delay to
prevent cold air delivery before heat exchanger warms up
(Gas heat only).

MOTORIZED OUTDOOR AIR DAMPERS - Outdoor and
return air dampers that are interlocked and positioned by
a 2-position, spring-return damper actuator. The maxi-
mum leakage rate for the outdoor air intake dampers
shall not exceed 2% when dampers are fully closed and
operating against a pressure differential of 0.5 IWG. A
unit-mounted potentiometer shall be provided to adjust
the outdoor and return air damper assembly to take in
the design CFM of outdoor air to meet the ventilation
requirements of the conditioned space during normal
operation. Whenever the indoor fan motor is energized,
the dampers open up to one of two pre-selected posi-
tions - regardless of the outdoor air enthalpy. Dampers
return to the fully closed position when the indoor fan
motor is de-energized. Dampers shall fully close on
power loss.

ELECTRONIC ENTHALPY AUTOMATIC ECONO-
MIZER - Outdoor and return air dampers that are inter-
locked and positioned by a fully-modulating, spring-
return damper actuator. The maximum leakage rate for
the outdoor air intake dampers shall not exceed 2%
when dampers are fully closed and operating against a
pressure differential of 0.5 IWG. A unit-mounted potenti-
ometer shall be provided to adjust the outdoor and return
air damper assembly to take in CFM of outdoor air to
meet the minimum ventilation requirement of the condi-
tioned space during normal operation. During econo-
mizer operation, a mixed-air temperature control shall
modulate the outdoor and return air damper assembly to
prevent the supply air temperature from dropping below
55°F. Changeover from compressor to economizer oper-
ation shall be provided by an integral electronic enthalpy
control that feeds input into the basic module. The out-
door intake opening shall be covered with a rain hood
that matches the exterior of the unit. Water eliminator/fil-
