DESCRIPTION
The Momentum™ Series AL21 variable capacity air condition-
ers are the outdoor section of a high efficiency communicating
cooling system. They are designed as part of a matched system
using an AVV air handler or variable speed communicating fur-
nace with a CM coil. Both the matched CM coil and AVV air
handler have factory mounted EEVs. The CM coils with factory
mounted EEVs can also be matched with the variable speed
MVC modular air handlers.
FEATURES
• Superior Coil Protection – An easily removable two-piece
steel extruded louver coil guard protects the tube-in-fin coil
from debris and physical damage while making access for
coil cleaning quick and simple.
• Environmentally Friendly Refrigerant – The next genera-
tion refrigerant R-410A delivers environmentally friendly per-
formance with zero ozone depletion.
• Durable Finish – A high quality powder paint finish rated at
1000 hrs. salt spray provides the ultimate protection from
corrosion and harmful UV rays, ensuring a long-lasting, high
quality appearance.
• Charge Guard™ – A built-in touch screen instantly displays
the system overall condition, including the system pressures
and refrigerant charge without the need to attach additional
gauges or sensors.
• Sound Reducing System – Features a combination of engi-
neered, sound-neutralizing attributes such as a swept-wing
fan blade, composite base pan, multi-density compressor
cloak and variable capacity operation to reduce sound levels
to that of a mere conversation.
• ECM Fan Motor – Dynamically adjusts speed in sync with
the compressor demand to keep heat exchange in balance
while minimizing power consumption and sound.
• Swept Wing Fan – A design adapted from aerospace engi-
neering provides whisper-quiet operation by allowing air to
flow smoothly and efficiently across the fan surface and
edges.
• Composite Base Pan – The strong and durable composite
base pan is corrosion resistant while adding strength,
absorbing sound, and reducing vibration.
• High-Efficiency Outdoor Coil – An aluminum fin and cop-
per tube outdoor coil provide easy cleaning, low restriction to
airflow and efficient heat exchange.
• Factory Installed Filter-Drier – A corrosion resistant copper
solid core liquid line filter-drier removes debris and moisture
which can be harmful to the system.
• Climate Mark™ – provides pre-configured operating profiles
the installing contractor can select during set-up to fine tune
the system's operation for either Humid, Dry, or Normal cli-
mates. Additional fine-tune adjustments are always available
to provide a custom comfort solution.
• Easy Service Access – A large electrical box cover, inde-
pendent Charge Guard access, and a swing open electrical
box provide superior full corner access to the inside of the
unit for maintenance or service.
• System Protection – Each system contains high and low
pressure transducers which constantly monitor system per-
formance and can alert the consumer or contractor system
concerns or alerts.
• EEV Controls – All indoor coils, whether in the cased CM
coil or in the AVV air handler, have factory installed EEVs
(Electronic Expansion Valves).
