Quiet operation

The Carrier Console WSHP provides
exceptionally quiet operation for maxi-
mum comfort.

Design flexibility

Aquazone™ Console WSHP units are
offered in 5 capacity sizes and 3 differ-
ent voltages to meet individual zone
needs efficiently and effectively.
Standard and extended operating
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

accordance with ARI/ISO/ASHRAE
13256-1 performance standard, and
are CSA/NRTL 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 R-22
refrigerant.

Water connections are available in a

variety of configurations direct from
the factory. The standard configuration
is

in. OD Sweat connections for

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.

in. ID vinyl condensate con-

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 (with 3 in. subbase). For flex-
ibility, the controls can be mounted on
the top right or left side. Additionally,
the sloped top design discourages the
use of the unit as a shelf or coffee hold-
er, 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
easy access to the controls.

Fan motor sleeve bearings are

permanently lubricated for worry-free
performance. If the unit does require
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 control (DDC) applications in-
clude the Carrier Comfort Network
(CCN) 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
accommodating accessory loads.
