FACTORY OPTIONS AND/OR ACCESSORIES FOR PACKAGE AIR CONDITIONER
Economizer (dry--bulb or enthalpy)
Economizers save money. They bring in fresh, outside air
for ventilation; and provide cool, outside air to cool your
building. This is the preferred method of low--ambient
cooling. When coupled to CO2 sensors, economizers can
provide even more savings by coupling the ventilation air
to only that amount required.
Economizers are available, installed and tested by the
factory, with either enthalpy or dry--bulb temperature
inputs. There are also models for electromechanical as
well as direct digital controllers. Additional sensors are
available as accessories to optimize the economizers.
Economizers include gravity controlled, barometric relief
equalizes building pressure and ambient air pressures.
This can be a cast effective solution to prevent building
pressurization.
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. Carrier 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 (powered or un--powered)
Reduce service and/or installation costs by including a
convenience outlet in your specification. Carrier 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 “unpowered” option is
to be powered from a separate 115/120v power source.
Non--fused Disconnect
This OSHA--compliant, factory--installed, safety switch
allows a service technician to locally secure power to the
rooftop.
Power Exhaust with Barometric Relief
Superior internal building pressure control. This
field--installed accessory may eliminate the need for
costly, external pressure control fans.
PremierLinkt, DDC Controller
This CCN controller regulates your rooftop’s performance
to tighter tolerances and expanded limits, as well as
facilitates zoning systems and digital accessories. It also
unites your Carrier HVAC equipment together on one,
coherent CCN network. The PremierLink can be
factory--installed, or easily field--installed.
RTU Open, Multi--Protocol Controller
Connect the rooftop to an existing BAS without needing
complicated translators or adapter modules using the RTU
Open controller. This new controller speaks the 4 most
common building automation system languages (Bacnet,
Modbus, N2, and Lonworks). Use this controller when
you have an existing BAS. Besides the 4 protocols, it also
communicates with a Carrier Open system (I--Vu and
VVT).
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. Not required with PremierLink, RTU Open, or
authorized commercial thermostats.
Motorized 2--Position Damper
The new Carrier 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 Humidi--MiZer Adaptive
Dehumidification System
Carrier’s Humidi--MiZer adaptive dehumidification
system is an all--inclusive factory installed option that can
be ordered with any rooftop unit.
This system expands the envelope of operation of
Carrier’s WeatherMaster rooftop products to provide
unprecedented flexibility to meet year round comfort
conditions.
The Humidi--MiZer adaptive dehumidification system has
the industry’s only dual dehumidification mode setting.
The Humidi--MiZer system includes two new modes of
operation.
Optional Humidi--MiZer Adaptive
Dehumidification System
rooftop coupled with the
Humidi--MiZer 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.
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.
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.
Motormaster Head Pressure Controller
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 not 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 Carrier extends the low ambient
limit of your rooftop to 25_F (--4_C). 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.
Flue Discharge Deflector
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 (04--12
models only).
Optional Stainless Steel Heat Exchanger
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
45_F (7_C). Stainless steel may be specified on
applications where the presence of airborne contaminants
require its use (applications such as paper mills) or in area
with very high outdoor humidity that may result in severe
condensation in the heat exchanger during cooling
operation.
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 (04--12 models only).
Alternate Motors and Drives
Some applications need larger horsepower motors, some
need more airflow, and some need both. Regardless of the
case, your Carrier 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.
Economizer (dry--bulb or enthalpy)
