FACTORY OPTIONS AND/OR ACCESSORIES
Economizer
Non−fused Disconnect
Economizers save energy, money and improve
comfort levels in the conditioned space. They bring in
fresh, outside air for ventilation; and provide cool
outside air to cool your building. This also is the
preferred method of low ambient cooling. When
integrated with CO2 sensors, economizers can
provide even more savings by coupling the ventilation
air to only that amount required based on space
occupancy. Economizers are available, installed and
tested by the factory, with either enthalpy or
temperature dry−bulb inputs. There are also models
for electromechanical and direct digital controllers.
Additional sensors are available as accessories to
optimize the economizer. Economizers include gravity
controlled barometric relief that helps equalize
building pressure and ambient air pressures. This can
be a cost effective solution to prevent building
pressurization. Economizers are available in Ultra
Low Leak and standard low leak versions.
This OSHA−compliant, factory installed, safety switch
allows a service technician to locally secure power to
the rooftop.
CO2 Sensor
Improves productivity and saves money by working
with the economizer to intake only the correct amount
of outside air for ventilation. As occupants fill your
building, the CO2 sensor detects their presence
through increasing CO2 levels, and opens the
economizer appropriately.
When the occupants leave, the CO2 levels decrease,
and the sensor appropriately closes the economizer.
This intelligent control of the ventilation air, called
Demand Control Ventilation (DCV) reduces the
overall load on the rooftop, saving money.
Smoke Detectors
Trust the experts. Smoke detectors make your
application safer and your job easier. ICP smoke
detectors immediately shut down the rooftop unit
when smoke is detected. They are available, installed
by the factory, for supply air, return air, or both.
Louvered Hail Guards
Sleek, louvered panels protect the condenser coil
from hail damage, foreign objects, and incidental
contact.
Convenience Outlet (un−powered)
Reduce service and/or installation costs by including
a convenience outlet in your specification. ICP will
install this service feature at our factory. Provides a
convenient, 15 amp, 115v GFCI receptacle with “Wet
in Use” cover. The “powered” option allows the
installer to power the outlet from the line side of the
disconnect or load side as required by code. The
“un−powered” option is to be powered from a
separate 115/120v power source.
4
Power Exhaust with Barometric Relief
Superior internal building pressure control. This field
installed accessory may eliminate the need for costly,
external pressure control fans.
Time Guard II Control Circuit
This accessory protects your compressor by
preventing short−cycling in the event of some other
failure, prevents the compressor from restarting for
30 seconds after stopping.
Motorized 2−Position Damper
The ICP 2−position, motorized outdoor air damper
admits up to 100% outside air. Using reliable,
gear−driven technology, the 2−position damper opens
to allow ventilation air and closes when the rooftop
stops, stopping unwanted infiltration.
Manual OA Damper
Manual outdoor air dampers are an economical way
to bring in ventilation air. The dampers are available
in 25% and 50% versions.
Optional Hot Gas ReHeat
Dehumidification System
Hot Gas ReHeat Dehumidification System is an
all−inclusive factory installed option that can be
ordered with any 3 phase RGX36−60 rooftop unit.
This system expands the envelope of operation of
rooftop products to provide unprecedented flexibility
to meet year round comfort conditions.
The Hot Gas ReHeat dehumidification system has the
industry’s only dual dehumidification mode setting.
The Hot Gas ReHeat system includes two new
modes of operation.
The RGX36−60 rooftop coupled with the Hot Gas
ReHeat system is capable of operating in normal
design cooling mode, subcooling mode, and Hot Gas
ReHeat mode. Normal design cooling mode is when
the unit will operate under its normal sequence of
operation by cycling compressors to maintain comfort
conditions.
Specifications subject to change without notice.
509 41 4300 01
FACTORY OPTIONS AND/OR ACCESSORIES (cont.)
Subcooling mode will operate to satisfy part load type
conditions when the space requires combined
sensible and a higher proportion of latent load control.
Hot Gas ReHeat mode will operate when outdoor
temperatures diminish and the need for latent
capacity is required for sole humidity control. Hot Gas
ReHeat mode will provide neutral air for maximum
dehumidification operation.
Flue Discharge Deflector
Motormaster Head Pressure Controller
The stainless steel heat exchanger option provides
the tubular heat exchanger be made out of a
minimum 20 gauge type 409 stainless steel for
applications where the mixed air to the heat
exchanger is expected to drop below 45F (7C).
Stainless steel may be specified on applications
where the presence of airborne contaminants require
its use (applications such as paper mills) or in areas
with very high outdoor humidity that may result in
severe condensation in the heat exchanger during
cooling operation.
The Motormaster motor controller is a low ambient,
head pressure controller kit that is designed to
maintain the unit’s condenser head pressure during
periods of low ambient cooling operation. This device
should be used as an alternative to economizer free
cooling when economizer usage is either not
appropriate or desired. The Motormaster will either
cycle the outdoor fan motors or operate them at
reduced speed to maintain the unit operation,
depending on the model.
Winter Start Kit
The winter start kit by ICP extends the low ambient
limit of your rooftop to 25F (−4C). The kit bypasses
the low pressure switch, preventing nuisance tripping
of the low pressure switch. Other low ambient
precautions may still be prudent.
Propane Heating
Convert your gas heat rooftop from standard natural
gas operation to propane using this field installed kit.
High Altitude Heating
High altitudes have less oxygen, which means heat
exchangers need less fuel. The new gas orifices in
this field installed kit make the necessary adjustment
for high altitude applications. They restore the optimal
fuel to air mixture and maintain healthy combustion at
altitudes above 2000 ft (610m). Kits may not be
required in all areas.
Hinged Access Panels
Allows access to unit’s major components with
specifically designed hinged access panels. Panels
are: filter, control box, fan motor, and compressor.
The flue discharge deflector is a useful accessory
when flue gas recirculation is a concern. By venting
the flue discharge upwards, the deflector minimizes
the chance for a neighboring unit to intake the flue
exhaust.
Optional Stainless Steel Heat Exchanger
Flue Discharge Heat Shield
The flue discharge heat shield keeps people from
touching the rooftop unit’s potentially hot flue
discharge. This is especially useful for ground level
applications, where more, untrained people could
have access to the unit’s exterior.
Alternate Motors and Drives
Some applications need larger horsepower motors,
some need more airflow, and some need both.
Regardless of the case, your ICP expert has a factory
installed combination to meet your application. A wide
selection of motors and pulleys (drives) are available,
factory installed, to handle nearly any application.
Thru−the−Base Connections
Thru−the−base connections, available as either an
accessory or as a factory option, are necessary to
ensure proper connection and seal when routing wire
and piping through the rooftop’s basepan and curb.
These couplings eliminate roof penetration and
should be considered for gas lines, main power lines,
as well as control power.

NOTES:
1. Outdoor sound data is measure in accordance with AHRI
standard 270.
2. Measurements are expressed in terms of sound power. Do not
compare these values to sound pressure values because
sound pressure depends on specific environmental factors
which normally do not match individual applications. Sound
power values are independent of the environment and therefore more accurate.
3. A−weighted sound ratings filter out very high and very low frequencies, to better approximate the response of “average” human ear. A−weighted measurements for ICP units are taken in
accordance with AHRI standard 270.

APPLICATION DATA
Min operating ambient temp (cooling):
In mechanical cooling mode, your ICP rooftop unit
can safely operate down to an outdoor ambient
temperature of 40F (4C) and 25F (−4C), with an
accessory winter start kit. It is possible to provide
cooling at lower outdoor ambient temperatures by
using less outside air, economizers, and/or accessory
low ambient kits.
Max operating ambient temp (cooling):
The maximum operating ambient temperature for
cooling mode is 115F (46C). While cooling
operation above 115F (46C) may be possible, it
could cause either a reduction in performance,
reliability, or a protective action by the unit’s internal
safety devices.
Min mixed air temp (heating):
Using the factory settings, the minimum temperatures
for the mixed air (the combined temperature of the
warm return air and the cold outdoor air) entering the
dimpled, gas heat exchangers are:
14
Aluminized
Stainless Steel
50F (10C) continuous
45F (7C) intermittent
40F (4C) continuous
35F (2C) intermittent
Operating at lower mixed−air temperatures may be
possible, if a field supplied, outdoor air thermostat
initiates both heat stages when the temperature is
less than the minimum temperatures listed above.
Please contact your local ICP representative for
assistance.
Min and max airflow (heating and cooling):
To maintain safe and reliable operation of your
rooftop, operate within the heating airflow limits during
heating mode and cooling airflow limits during cooling
mode. Operating above the max may cause blow−off,
undesired airflow noise, or airflow related problems
with the rooftop unit. Operating below the min may
cause problems with coil freeze−up and unsafe
heating operation. Heating and cooling limitations
differ when evaluating operating cfm, the minimum
value is the HIGHER of the cooling and heating
Specifications subject to change without notice.
509 41 4300 01
minimum cfm values published in Table 6 and the
maximum value is the LOWER of the cooling and
heating maximum values published in Table 6.
Heating−to−cooling changeover:
Your unit will automatically change from heating to
cooling mode when using a thermostat with an
auto−changeover feature.
Airflow:
All units are draw−through in cooling mode and
blow−through in heating mode.
Outdoor air application strategies:
Economizers reduce operating expenses and
compressor run time by providing a free source of
cooling and a means of ventilation to match
application changing needs. In fact, they should be
considered for most applications. Also, consider the
various economizer control methods and their
benefits, as well as sensors required to accomplish
your application goals. Please contact your local ICP
representative for assistance.
Motor limits, Brake horsepower (BHP):
Due to internal design of ICP units, the air path, and
specially designed motors, the full horsepower
(maximum continuous BHP) band, as listed in Table 8
and 10, can be used with the utmost confidence.
There is no need for extra safety factors, as ICP
motors are designed and rigorously tested to use the
entire, listed BHP range without either nuisance
tripping or premature motor failure.
Propane heating:
Propane has different physical qualities than natural
gas. As a result, propane requires different fuel to air
mixture. To optimize the fuel/air mixture for propane,
ICP sells different burner orifices in an easy to install
accessory kit. To select the correct burner orifices or
determine the heat capacity for a propane application,
use either the selection software, or the unit’s service
manual.
High altitude heating:
High altitudes have less oxygen, which affects the
fuel/air mixture in heat exchangers. In order to
maintain a proper fuel/air mixture, heat exchangers
operating in altitudes above 2000 ft (610 m) require
different orifices. To select the correct burner orifices
or determine the heat capacity for a high altitude
application, use either the selection software, or the
unit’s service manual.
NOTE: Typical natural gas heating value ranges from
975 to 1050 Btu/ft3 at sea level nationally. The
heating value goes down approximately 1.7% per
every thousand feet elevation. Standard factory
orifices can typically be used up to 2000 ft (610m)
elevation without any operational issues.
NOTE: For installations in Canada, the input rating
should be derated by 10% for altitudes from 2000 ft
(610m) to 4500 ft (1372m) above sea level.
Sizing a rooftop
Bigger isn’t necessarily better. While an air
conditioner needs to have enough capacity to meet
the design loads, it doesn’t need excess capacity. In
fact, excess capacity typically results in very poor part
load performance and humidity control.
Using higher design temperatures than ASHRAE
recommends for your location, adding “safety factors”
to the calculated load, are all signs of oversizing air
conditioners. Oversizing the air conditioner leads to
poor humidity control, reduced efficiency, higher utility
bills, larger indoor temperature swings, excessive
noise, and increased wear and tear on the air
conditioner.
Rather than oversizing an air conditioner, engineers
should “right size” or even slightly undersize air
conditioners. Correctly sizing an air conditioner
controls humidity better; promotes efficiency; reduces
utility bills; extends equipment life, and maintains
even, comfortable temperatures. Please contact your
local ICP representative for assistance.
Low ambient applications
The optional ICP economizer can adequately cool
your space by bringing in fresh, cool outside air. In
fact, when so equipped, accessory low ambient kit
may not be necessary. In low ambient conditions,
unless the outdoor air is excessively humid or
contaminated, economizer based “free cooling” is the
preferred less costly and energy conscious method.
In low ambient applications where outside air might
not be desired (such as contaminated or excessively
humid outdoor environments), your ICP rooftop can
operate at ambient temperatures down to −20F
(−29C) using the recommended accessory
Motormaster low ambient controller.
High altitudes have less oxygen, which means heat
exchangers need less fuel. The new gas orifices in
this field installed kit make the necessary adjustment
for high altitude applications. They restore the optimal
fuel to air mixture and maintain healthy combustion
on altitudes above 2000 ft (610 m).

GENERAL FAN PERFORMANCE NOTES
5. Interpolation is permissible. Do not extrapolate.
6. External static pressure is the static pressure difference between the return duct and the supply duct plus
the static pressure caused by any FIOPs or accessories.
7. Tabular data accounts for pressure loss due to clean filters, unit casing, and wet coils. Factory options and
accessories may add static pressure losses. Selection software is available, through your salesperson, to
help you select the best motor/drive combination for your application.
8. The Fan Performance tables offer motor/drive recommendations. In cases when two motor/drive combinations would work, ICP recommended the lower horsepower option.
9. For information on the electrical properties of ICP motors, please see the Electrical information section of
this book.
10. For more information on the performance limits of ICP motors, see the application data section of this book.
11. The EPACT (Energy Policy Act of 1992) regulates energy requirements for specific types of indoor fan motors. Motors regulated by EPACT include any general purpose, T−frame (three−digit, 143 and larger), single−
speed, foot mounted, polyphase, squirrel cage induction motors of NEMA (National Electrical Manufacturers
Association) design A and B, manufactured for use in the United States. Ranging from 1 to 200 Hp, these
continuous−duty motors operate on 230 and 460 volt, 60 Hz power. If a motor does not fit into these specifications, the motor does not have to be replaced by an EPACT compliant energy efficient motor. Variable
speed motors are exempt from EPACT compliance requirements. Therefore, the indoor fan motors for ICP
RGX36−60 units are exempt from these requirements.

= 100 x
average voltage
Example: Supply voltage is 230-3-60
AB = 224 v
BC = 231 v

Determine maximum deviation from average voltage.
(AB) 227 – 224 = 3 v
(BC) 231 – 227 = 4 v
(AC) 227 – 226 = 1 v
Maximum deviation is 4 v.
Determine percent of voltage imbalance.

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.
SEQUENCE OF OPERATION
General
The sequence below describes the sequence of
operation for an electromechanical unit with and without
a factory installed EconoMi$er IV and X (called
“economizer” in this sequence). For information
regarding a direct digital controller, see the start−up,
operations, and troubleshooting manual for the
applicable controller.
Electromechanical units with no economizer
Cooling (Single speed indoor fan motor) —
When the thermostat calls for cooling, terminals G and
Y1 are energized. As a result, the indoor fan contactor
(IFC) and the compressor contactor (C1) are energized,
causing the indoor fan motor (IFM), compressor #1, and
outdoor fan to start. If the unit has 2 stages of cooling,
the thermostat will additionally energize Y2. The Y2
signal will energize compressor contactor #2 (C2),
causing compressor #2 to start. Regardless of the
number of stages, the outdoor fan motor runs
continuously while unit is cooling. When SAV system is
utilized, indoor fan motor runs at design CFM (full
speed) during the heating operation.
Heating (Single speed indoor fan motor) —
When the thermostat calls for heating, power is sent to
W on the Integrated Gas Controller (IGC) board. An
LED (light−emitting diode) on the IGC board turns on
and remains on during normal operation. A check is
made to ensure that the rollout switch and limit switch
are closed. If the check was successful, the
induced−draft motor is energized, and when its speed is
satisfactory, as proven by the “hall effect” sensor, the
ignition activation period begins. The burners will ignite
within 5 seconds. If the burners do not light, there is a
22−second delay before another 5−second attempt.
This sequence is repeated for 15 minutes or until the
509 41 4300 01
burners light. If, after the 15 minutes, the burners still
have not lit, heating is locked out. To reset the control,
break 24−v power to the thermostat.
When ignition occurs, the IGC board will continue to
monitor the condition of the rollout switch, the limit
switches, the “hall effect” sensor, as well as the flame
sensor. 45 seconds after ignition occurs, assuming the
unit is controlled through a room thermostat set for fan
auto, the indoor fan motor will energize (and the outdoor
air dampers will open to their minimum position). If, for
some reason, the over−temperature limit opens prior to
the start of the indoor fan blower, the unit will shorten
the 45−second delay to 5 seconds less than the time
from initiation of heat to when the limit tripped. Gas will
not be interrupted to the burners and heating will
continue. Once the fan−on delay has been modified, it
will not change back to 45 seconds until power is reset
to the control.
On units with 2 stages of heat, when additional heat is
required, W2 closes and initiates power to the second
stage of the main gas valve. When the thermostat is
satisfied, W1 and W2 open and the gas valve closes,
interrupting the flow of gas to the main burners.
If the call for W1 lasted less than 1 minute, the heating
cycle will not terminate until 1 minute after W1 became
active. If the unit is controlled through a room
thermostat set for fan auto, the indoor fan motor will
continue to operate for an additional 45 seconds then
stop. If the over−temperature limit opens after the indoor
motor is stopped, but within 10 minutes of W1 becoming
inactive, on the next cycle the time will be extended by
15 seconds. The maximum delay is 3 minutes. Once
modified, the fan off delay will not change back to 45
seconds unless power is reset to the control. A LED
indicator is provided on the IGC to monitor operation.
Specifications subject to change without notice.

SEQUENCE OF OPERATION (cont.)
Electromechanical units with an economizer
Cooling —
When free cooling is not available, the compressors will
be controlled by the zone thermostat. When free cooling
is available, the outdoor air damper is modulated by the
EconoMi$er IV and X control to provide a 50F (10C)
to 55F (13C) mixed air temperature into the zone. As
the mixed air temperature fluctuates above 55F
(13C)or below 50F (10C) dampers will be modulated
(open or close) to bring the mixed air temperature back
within control. If mechanical cooling is utilized with free
cooling, the outdoor air damper will maintain its current
position at the time the compressor is started. If the
increase in cooling capacity causes the mixed air
temperature to drop below 45F (7C), then the outdoor
air damper position will be decreased to the minimum
position. If the mixed air temperature continues to fall,
the outdoor air damper will close. Control returns to
normal once the mixed air temperature rises above
48F (9C). The power exhaust fans will be energized
and de−energized, if installed, as the outdoor air
damper opens and closes.
If field installed accessory CO2 sensors are connected
to the EconoMi$er IV and X control, a demand
controlled ventilation strategy will begin to operate. As
the CO2 level in the zone increases above the CO2
setpoint, the minimum position of the damper will be
increased proportionally. As the CO2 level decreases
because of the increase in fresh air, the outdoor air
damper will be proportionally closed. For EconoMi$er IV
and X operation, there must be a thermostat call for the
fan (G).
If the unit is occupied and the fan is on, the damper will
operate at minimum position. Otherwise, the damper will
be closed.
If field installed accessory CO2 sensors are connected
to the EconoMi$er IV and X control, a demand
controlled ventilation strategy will begin to operate. As
the CO2 level in the zone increases above the CO2
setpoint, the minimum position of the damper will be
increased proportionally. As the CO2 level decreases
because of the increase in fresh air, the outdoor air
damper will be proportionally closed. For EconoMi$er IV
and X operation, there must be a thermostat call for the
fan (G). If the unit is occupied and the fan is on, the
damper will operate at minimum position. Otherwise, the
damper will be closed.
When the EconoMi$er IV and X control is in the
occupied mode and a call for cooling exists (Y1 on the
thermostat), the control will first check for indoor fan
operation. If the fan is not on, then cooling will not be
activated. If the fan is on, then the control will open the
EconoMi$er IV and X damper to the minimum position.
36
On the initial power to the EconoMi$er IV and X control,
it will take the damper up to 2 1/2 minutes before it
begins to position itself. After the initial power−up,
further changes in damper position can take up to 30
seconds to initiate. Damper movement from full closed
to full open (or vice versa) will take between 1 1/2 and 2
1/2 minutes. If free cooling can be used as determined
from the appropriate changeover command (switch, dry
bulb, enthalpy curve, differential dry bulb, or differential
enthalpy), then the control will modulate the dampers
open to maintain the mixed air temperature setpoint at
50F (10C) to 55F (13C). If there is a further
demand for cooling (cooling second stage − Y2 is
energized), then the control will bring on compressor
stage 1 to maintain the mixed air temperature setpoint.
The EconoMi$er IV and X damper will be open at
maximum position.
Heating
The sequence of operation for the heating is the same
as an electromechanical unit with no economizer. The
only difference is how the economizer acts. The
economizer will stay at the Economizer Minimum
Position while the evaporator fan is operating. The
outdoor air damper is closed when the indoor fan is not
operating.
Optional Hot Gas ReHeat Dehumidification System
Units with the factory equipped Hot Gas ReHeat option
are capable of providing multiple modes of improved
dehumidification as a variation of the normal cooling
cycle. The Hot Gas ReHeat option includes additional
valves in the liquid line and discharge line of each
refrigerant circuit, a small reheat condenser coil
downstream of the evaporator, and Motormaster
variable−speed control of some or all outdoor fans.
Operation of the revised refrigerant circuit for each
mode is described below.
The Hot Gas ReHeat system provides three sub−modes
of operation: Cool, Reheat1, and Reheat2.
Cool mode − provides a normal ratio of Sensible and
Latent Cooling effect from the evaporator coil.
Reheat1 − provides increased Latent Cooling while
slightly reducing the Sensible Cooling effect.
Reheat2 − provides normal Latent Cooling but with null
or minimum Sensible Cooling effect delivered to the
space.
The Reheat1 and Reheat2 modes are available when
the unit is not in a Heating mode and when the Low
Ambient Lockout switch is closed.
The following diagrams depict piping for Single Stage
cooling units.
