Single-stage WSHP models with Pu-
ron refrigerant (R-410A) offer cooling
EERs (Energy Efficiency Ratios) to
24.5 and heating COPs (Coefficiency
of Performance) to 5.0.
All efficiencies stated are in accor-
dance with standard conditions under
ISO (International Organization for
Standardization) Standard 13256-1
and provide among the highest ratings
in the industry, exceeding ASHRAE
(American Society of Heating, Refrig-
eration and Air Conditioning Engi-
neers) 90.1 Energy Standards.
High quality construction and
testing
All units are manufactured to meet
extensive quality control protocol from
start to finish through an automated
control system, which provides contin-
uous monitoring of each unit and
performs quality control checks as
equipment progresses through the
production process. Standard construc-
tion features of the Aquazone™ units
include:
Cabinet — Standard unit fabrication
consists of heavy gage galvanized sheet
metal cabinet construction designed for
part standardization (i.e., minimal
number of parts) and modular design.
Compressor section interior surfaces
are lined with
1

in. thick, dual densi-
ty, 1

lb per cubic ft acoustic type fi-
berglass insulation. Air-handling sec-
tion interior surfaces are lined with
1
/
2
in. thick, single density, 1
1
/
2
lb per
cubic ft foil-backed fiber insulation for
ease of cleaning. Insulation placement
is designed to eliminate any exposed
edges to prevent the introduction of
glass fibers into the airstream.
Horizontal and vertical water source
heat pumps are fabricated from heavy
gage galvanized steel with a powder
coat paint finish on the front access
panel.
Compressor — Aquazone 50P1
single-stage units include a rotary
compressor in sizes 006-018 and a
scroll compressor in sizes 024-060.
Single-stage models with Puron
®
re-
frigerant (R-410A) offer a dual level vi-
bration isolation system. The compres-
sor is mounted on computer selected
vibration isolation springs to a large
heavy gage compressor mounting tray
plate, which is then isolated from the
cabinet base with rubber grommets for
maximized vibration attenuation. The
compressor has thermal overload pro-
tection and is located in an insulated
compartment away from the airstream
to minimize sound transmission.
AHRI/ISO labels — Aquazone units
have AHRI (Air Conditioning, Heating,
and Refrigeration Institute)/ISO, NRTL
(Nationally Recognized Testing Lab), or
ETL labels and are factory tested under
normal operating conditions at nomi-
nal water flow rates. Quality assurance
is provided via testing report cards
shipped with each unit to indicate spe-
cific unit performance under cooling
and heating modes of operation.
Blower and motor assembly —
Aquazone 50P1 units are available
with permanent split capacitor (PSC)
or high-static PSC motors.
NOTE: The PSC and high-static PSC
blower motors, when used with a
Thermidistat device and/or a humid-
istat and the Deluxe D controls, allow
for intelligent fan speed reduction to
provide the IdealHumidity™ system.
The variable-speed blower systems
work in concert with the Thermidistat
and/or humidistat control to remove
more moisture than a standard system,
making the occupants feel cool and
more comfortable.
Refrigeration/water circuit — All
units contain sealed Puron refrigerant
(R-410A) circuits including a high-
efficiency hermetic compressor de-
signed for heat pump operation, a
thermostatic expansion valve for refrig-
erant metering, an enhanced corrugat-
ed aluminum-lanced fin and rifled cop-
per tube refrigerant-to-air heat ex-
changer, reversing valve, coaxial (tube-
in-tube) refrigerant-to-water heat ex-
changer, and safety controls including
a high-pressure switch, low-pressure
switch, water coil low temperature
sensor, and air coil low temperature
sensor.
Quiet operation
Fan motor insulation and double
isolated compressor are provided for
sound isolation, cabinets are fully insu-
lated to reduce noise transmission, low
speed blowers are utilized for quiet op-
eration through reduced outlet air
velocities, and air-to-refrigerant coils
are designed for lower airflow coil face
velocities. Additional sound mitigation
can be attained with the mute package
option.
Puron
®
refrigerant (R-410A)
Puron refrigerant (R-410A) is a non-
chlorine based refrigerant. Puron re-
frigerant characteristics, compared to
R-22, have:
• Binary and near azeotropic mixture
of 50% R-32 and 50% R-125.
• Higher efficiencies (50 to 60%
higher operating pressures).
• Non-ozone depleting potential and
low global warming potential.
• Virtually no glide. Unlike other
alternative refrigerants, the two
components in Puron refrigerant
have virtually the same leak rates.
Therefore, refrigerant can be added
if necessary without recovering the
charge.
