High quality construction and
testing
All units are manufactured to meet ex-
tensive quality control standards. An
automated control system provides
continuous monitoring of each unit
and performs quality control checks as
equipment progresses through the pro-
duction process. Standard construction
features of the Carrier Aquazone™
units include:
Cabinet —
Heavy gage galvanized
sheet metal cabinet construction en-
ables part standardization (i.e., minimal
number of parts) and modular design.
Cabinet interior surfaces are lined with
1
/
2
in. thick, 1
3
/
4
lb acoustic type insu-
lation. Sheet metal surfaces are treated
for maximum corrosion protection to
ensure resilience for long term vitality.
Compact cabinet dimensions fit tight
space limitations in both horizontal and
vertical configurations.
Compressor —
Aquazone standard
efficiency units include a rotary com-
pressor in sizes 006 through 012, a
reciprocating compressor in sizes 018
through 048 and a scroll compressor
in size 060 units. Compressors are
mounted on an isolated system (i.e.,
from the cabinet) that maximizes vibra-
tion isolation and minimizes transmis-
sion to the unit structure.
Blower and motor assembly —
Permanent split capacitor (PSC) three-
speed (two-speed for 575 v) blowers
are provided with all units to satisfy
many air distribution applications.
Blower upgrades are available for high-
static conditions. Fan speed control
allows reduced sound operation. Blow-
er motors operate at lower tempera-
tures to help improve the reliability of
the water source heat pump.
Refrigeration/water circuit —
Most units have a sealed refrigerant cir-
cuit including a high-efficiency rotary,
reciprocating or scroll compressor.
Simplified refrigerant circuits provide
easy maintenance, higher accuracy
and excellent performance. Also
standard are a reversing valve (4-way
valve), water-to-refrigerant coaxial
(tube in tube) coil, and enhanced
aluminum fin/rifled copper tube air to
refrigerant heat exchanger coil.
A modulating reheat option is avail-
able to provide 100% reheat and
neutral supply air to the space.
ARI/ISO
—
Aquazone units have ARI
(Air Conditioning & Refrigeration Insti-
tute)/ISO, NRTL (Nationally Recog-
nized Testing Lab), or CSA (Canadian
Standards Association) labels and are
factory tested under normal operating
conditions at nominal water flow rates.
Quality assurance is provided via test-
ing report cards shipped with each unit
to indicate specific unit performance
under cooling and heating modes.
Water source heat pumps are New
York City MEA (Materials Equipment
and Acceptance) 60-00-E rated.
Quiet operation
Fan motor isolation and hermetic
compressor springs provide sound
isolation, cabinets are fully insulated to
reduce noise transmission, low speed
blowers are used for quiet operation
through reduced outlet air velocities,
and air-to-refrigerant coils are designed
for lower airflow coil face velocities.
Design flexibility
Airflow configurations for horizontal
units are available in four patterns in-
cluding left or right return, and left,
right, or back discharge. Horizontal
units are field convertible from left or
right discharge to back discharge.
Vertical units are available in four air-
flow patterns including top discharge
with front, right or left return.
Standard water temperature range be-
tween 60
F and 95
F offers maximum
design flexibility for boiler/tower appli-
cations. Water flow rates as low as
1.5 gpm per ton assist with selection
from a various range of circulating
pumps. Factory-installed options are
offered to meet specific design
requirements.
Safe, reliable operation
Standard safety features for the refrig-
erant circuit include a high-pressure
switch, low-pressure sensor to detect
refrigerant loss. Equipment safety fea-
tures include water loop temperature
monitoring, voltage protection, water
coil freeze protection, and standard
electronic condensate overflow shut-
down. All safety features are tested and
run at the factory to assure proper op-
eration of all components and safety
switches.
All components are carefully de-
signed and selected for endurance,
durability, and carefree day-to-day
operation.
