Westinghouse 19 SEER, 10 HSPF iQ Drive Technical Manual

•

iQ Drive:  Inverter  driven  Samsung  rotary  compressor

provides five capacities in modulating operation from a two

stage thermostat.

•

  Interface control board: Two digit LED provides system

operation, status and diagnostic troubleshooting information.

  -  Utilizes a NOrDyNE: patented capacity control algorithm

to select the optimum system capacity level.

  -  System Protection: Internal controls monitor system

operation to protect the inverter drive and compressor.

-  Cooling operating temperature range: 50 °F to 125 °F.    

-  Locks out heat pump heating: below 0 °F.

-  Adaptive demand defrost: Provides additional energy

savings in heating by defrosting only when necessary.

  -  Five Minute restart Time Delay: When the unit shuts

down,  a  delay  keeps  the  unit  from  restarting,

eliminating the highest cause for compressor failure.

•  Suction  Accumulator:  Protection  from  liquid  flood  back

and future compressor failures.

•  R-410A Refrigerant: Environmentally friendly non-ozone

depleting refrigerant.

•  Compressor and Component Access: Designed to make

servicing easier for the contractor, hinge access panels are

provided to all controls and the compressor.

•  High  Efficiency  with  the  low  Sound  Levels:  Up  to  19

SEER with sound ratings of 59-73 depending upon operating

conditions.

•  Compressor Sound Blanket: Engineered to significantly

reduce unwanted compressor noise.

Blade: A heavy duty brushless DC motor for long lasting

reliability and engineered to provide quiet operation. Requires

no maintenance and is completely protected from rain and

snow.

•  Common  Suction  Service  Port:  This  port  allows  the

contractor  to  read  the  suction  pressure  in  all  modes  of

operation  without  removing  any  panels,  saving  time  and

increasing serviceability.

•  Discharge  muffler:  Reduces  compressor  noise  and

vibration.

•  High Pressure Switch: Protects against abnormally high

system  pressures.  Auto-reset  feature  prevents  nuisance

service visits.

•  Low  Pressure  Switch:  Protects  against  loss  of  system

refrigerant charge.

•  Liquid Line Filter Drier: Included with unit, field installed.

•  Copper Tube  /  Aluminum  Fin  Coils:  outdoor  coils  are

designed to optimize heat transfer, and increase durability

and reliability.

•  Louvered Condenser Guard: Durable metal guard protects

the coil from yard hazards and extreme weather.

•  Composite  Base  Pan:  Absorbs  sound  and  is  corrosion

resistant. Composite pan is also stronger and lighter than

steel.

•  Designed using galvanized steel: with a polyester urethane

coat finish. The 950 hour salt spray finish resists corrosion

50% better than comparable units.

•  One Piece Top/Orifice: Designed for maximum airflow and

quiet operation.

•  Removable Top Grille Assembly: Allows ease of service

from the top without disconnecting fan motor leads.

The  iQ  Drive

®

 heat  pump  system  features  modulating

compressor  technology  and  variable  speed  indoor  and
outdoor fan motors. This system is controlled from a two
stage  cooling  and  heating  heat  pump  thermostat. The
system has the capability of adding up to 18% of additional
cooling/heating above the rated capacity. The B6VMAX
air  handler  has  de-humidification  capabilities  from  the
thermostat or duct mounted humidistat.

 – This product offers a 10-year all-parts warranty.
 – This product offers a 10 year Quality Pledge to replace

the  entire  unit,  if  the  unit’s  major  component  (heat
exchanger or compressor) fails within the first 10 years
of  operation,  to  the  original  owner.  All  split  system
products must be installed with a matched indoor air
handler or indoor coil to qualify.

 – Consumer product registration required for both 10

year All Parts Warranty and Quality Pledge within a
limited period of time after the installation. See current
warranty  document  or  visit  our  consumer  web  for
warranty details.
