Features/Benefits (cont)
Quiet operation
The Carrier console WSHP provides
exceptionally quiet operation for maxi-
mum comfort.
Design flexibility
Aquazone™ console WSHP units are
offered in 4 capacity sizes to meet indi-
vidual zone needs efficiently and effec-
tively. Standard and extended operat-
ing range units are available to suit a
variety of application requirements.
Safe, reliable operation
Standard safety features include: high
and low pressure monitoring and field
selectable water and air coil freeze pro-
tection sensing. All safety controls may
be reset at the thermostat. Each unit is
tested and run at the factory to ensure
proper operation of all components
and safety switches.
All components are carefully
designed and selected for endurance,
durability, and carefree day-to-day
operation.
The water-to-refrigerant heat
exchanger has copper inner and steel
outer tubing which is painted on the
outside to provide corrosion resistance
protection. Cupronickel heat exchang-
ers are available and should be used on
all open loop applications.
Units are rated and certified in ac-
cordance with ARI (Air Conditioning
and Refrigeration Institute)/ISO (Inter-
national Organization for Standardiza-
tion)/ASHRAE (American Society of
Heating, Refrigerating and Air Condi-
tioning Engineers) 13256-1 perfor-
mance standard, and are CSA (Canadi-
an Standards Association)/NRTL (Na-
tionally Recognized Testing Lab) listed.

Installation ease
The unit is packaged for simple, low
cost handling, with minimal time re-
quired for installation. The console unit
arrives at the jobsite fully assembled to
minimize installation time and reduce
installation cost. All units are pre-wired
and factory charged with Puron
frigerant (R-410A).
Water connections are available in a
variety of configurations direct from
the factory. The standard configuration
is 5 / in. OD sweat connections for
8
maximum flexibility in the field. Both
FPT and MPT are available as factory-
installed options to improve installation
efficiency. Additionally, factory-
installed motorized water shutoff
valves are available for use on energy
conserving systems employing a
variable pumping technique.
The standard electrical connections
are made quickly and directly to a pow-
er distribution terminal block. To fur-
ther improve installation efficiency, a
fused or unfused disconnect switch as
well as a 20 amp plug and cord are
available as factory-installed options.
A 5 / in. ID vinyl condensate con-
8
nection is provided for connection to
the field-installed condensate line.
Compact cabinet design dimen-
sions are 12 in. deep, 48 in. wide and
24 in. tall. For flexibility, the controls
can be mounted on the top right or left
side. Additionally, the sloped top de-
sign discourages the use of the unit as
a shelf or coffee holder, preventing air
blockage and any spills from damaging
the unit.
No-fuss maintenance and
serviceability
Regular maintenance or service to the
console WSHP units require little time.
Large service access panels enable
quick inspection for problem solving
and the control box swings down for
® re- easy access to the controls.
Fan motor sleeve bearings are per-
manently lubricated for worry-free per-
formance. If the unit requires service,
an easily removable cabinet and slide-
out fan section make access simple.
Refrigerant circuit protection is de-
signed to result in fewer service calls.
Units are equipped with easily accessi-
ble service access ports on both the
suction and the discharge refrigerant
lines for on-site testing and environ-
mentally correct refrigerant recovery.
Filter racks provide easy filter access
for cleaning.
Maximum control flexibility
Aquazone water source heat pumps
provide reliable control operation using
a standard microprocessor board.
Flexible alternatives for many direct
digital controls (DDC) applications in-
clude the Carrier Comfort Network
(CCN) controls and open protocol
systems.
Carrier's Aquazone standard unit
solid-state control system, the Com-
plete C, provides control of the unit
compressor, reversing valve, fan, safety
features, and troubleshooting fault indi-
cation features. The Complete C is
one of the most user friendly, low cost,
and advanced control boards found in
the WSHP industry. Many features are
field selectable to provide the ultimate
in field installation flexibility. The
overall features of this standard control
system include:
50-va transformer - Assists in
Page
accommodating accessory loads.
Anti-short cycle timer - Provides a
minimum off time to prevent the unit
from short cycling. The 5-minute timer
energizes when the compressor is
deenergized, resulting in a 5-minute
delay before the unit can be restarted.
Random start relay - Ensures a
random delay in energizing each differ-
ent WSHP unit. This option minimizes
peak electrical demand during start-up
from different operating modes or after
building power outages.
