DESCRIPTION (Cont’d.)
All models (including those with an economizer) are suitable
for either downflow or sideflow duct connections. Models with
factory installed Power Exhaust are only suitable for bottom
duct connections. For downflow duct, remove the sheet
metal panels from the supply and return air openings through
the base of the unit. For sideflow duct, replace the supply and
return air panels on the rear of the unit with a side duct flange
accessory.
A fixed outdoor air intake assembly is shipped in the return air
compartment of all units without an economizer 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.
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.
All compressors include crankcase heat and internal pressure 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.
•
Simplicity ® Controls - Simplicity ® control boards
have standardized a number of features previously
available only as options or by utilizing additional
controls.
•
Low Ambient - An integrated low-ambient control
allows all units to operate in the cooling mode down
to 0ºF outdoor ambient without additional assistance. Optionally, the control board can be programmed to lockout the compressors when the
outdoor air temperature is low or when free cooling
is available.
•
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.
•
Fan Delays - Fan on and fan off delays are fully programmable. 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.
•
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 control board will alarm on ignition failures, compressor
lockouts and repeated limit switch trips.
•
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 gas heat models are built with two heating sections for two
equal stages of capacity control. Each section includes a
durable heat exchanger with aluminized steel tubes, a redundant gas valve, spark ignition, power venting, an ignition
module for 100% shut-off and all of the safety controls
required to meet the latest ANSI standards.
The gas supply piping can be routed into the heating compartment through a hole in the base pan of the unit or through
a knockout in the piping panel on the front of the unit.
•
The Simplicity® control board used in this product will
effectively operate the cooling system down to 0°F
when this product is applied in a comfort cooling
application for people. An economizer is typically
included in this type of application. When applying this
product for process cooling applications (computer
rooms, switchgear, etc.), please reference applications
bulletin AE-011-07 or call the applications department
for Unitary Products @ 1-877-UPG-SERV for
guidance. Additional accessories may be needed for
stable operation at temperatures below 30°F.
All electric heat models 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 provide 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.
The power supply wiring can be routed into the control box
through a threaded pipe connection in the base pan of the
unit. It can also be routed knockout in the wiring panel on the
front of the unit.
All models are available with factory mounted BAS Control.
Options are Novar, Honeywell, Johnson, or CPC.

FIELD-INSTALLED ACCESSORIES
•
accessory includes a rain hood, a bird screen and a fully
assembled damper. With bottom duct connections, the
damper should be mounted over the opening in the
return air panel. With horizontal ductwork, the accessory
should be mounted on the return air duct.
•
SINGLE INPUT ELECTRONIC ENTHALPY ECONOMIZERS - Includes a slide-in / plug-in damper assembly
with fully modulating spring-return motor actuator capable of introducing up to 100% outdoor air with nominal
1% leakage type dampers.
The enthalpy system contains one sensor that monitors
the outdoor air and determines when the air is cool
enough and dry enough to provide free cooling.
They're designed to fit inside the base rails of the unit
and include both a wood nailing strip and duct hanger
supports.
•
SIDE DUCT FLANGES - 25mm (1 in.) flanges replace
the supply and return air panels on the rear of the unit to
accommodate horizontal duct connections. These
flanges can also be used individually for bottom supply/
horizontal return or horizontal supply/bottom return.
•
WOOD SKID - Allows unit to be handled with 90” forks.
•
CO2 SENSOR - Senses CO2 levels and automatically
overrides the economizer when levels rise above the
present limits.
•
COIL GUARD - Customers can purchase a coil guard kit
to protect the condenser coil from damage.
•
PHASE MONITORS - Designed to prevent unit damage.
The phase monitor will shut the unit down in an out-ofphase condition.
The rainhood is painted to match the basic unit and must
be field-assembled before installing.
Power exhaust is not available as a field installed option.

1. These capacities are gross ratings. For net capacity, deduct the heat of the supply air blower motor. Refer to the appropriate
Blower Performance Table for the kW of the supply air blower motor.
2. These ratings include the condenser fan motors (Total 2.1 kW) and the compressor motors but not the supply air blower motor.

CFM, STATIC PRESSURE, AND POWER - ALTITUDE AND TEMPERATURE CORRECTIONS
order to use the indoor blower tables for high altitude applications, certain corrections are necessary.
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.
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
shown in Table 9 and Figure 1.
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 performance of the product at altitude.
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: At an elevation of 5,000 ft the indoor blower will still
deliver 6,000 CFM if the rpm is unchanged. However, Table
9 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 9 shows the correction factor to be
0.832.

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.
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.
Suppose that the corresponding BHP listed in the table is 3.2.
This value must be corrected for elevation.
BHP at 5,000 ft = 3.2 x .832 = 2.66
Corrected static pressure = 1.5 x 0.832 = 1.248 IWC
Corrected BHP = 4.0 x 0.832 = 3.328
Example 2: A system, located at 5,000 feet of elevation, is to
deliver 6,000 CFM at a static pressure of 1.5". Use the unit
blower tables to select the blower speed and the BHP
requirement.
Solution: As in the example above, no temperature information is given so 70°F is assumed.
