GENERAL DESCRIPTION
The QV series water-to-air heat pump provides an
unmatched combination of performance, features,
and flexibility for both high-performance new
construction applications and replacement of
existing water-to-air heat pumps.
All units are certified by the Air-Conditioning,
Heating, and Refrigeration Institute (AHRI) to
AHRI/ANSI/ASHRAE/ISO standard 13256-1 for
water-to-air and brine-to-air heat pumps at both
Water Loop Heat Pump and Ground Loop Heat
Pump application points. All QV Water-to-Air Heat
Pumps conform to UL 1995 standard and are
certified to CAN/CSA C22.2 No 236 by
Intertek-ETL. These units meet all current
applicable requirements of ASHRAE 90.1.
QV series units are available in two basic
configurations: Vertical Top-Supply Air (VT) and
Horizontal End-Supply Air or Straight-Through
Supply Air (HZ). Each of these configurations are
available with either left- or right-hand return air.
HZ models can have the supply air field converted
from end discharge air to straight through with no
extra parts required.
QV series units are designed to operate with
entering-fluid temperatures between 50°F and
100°F in cooling and 50°F and 80°F in heating with
the base configuration. With the extended range
option, QV series models can operate with
entering fluid temperatures between 50°F and
110°F in cooling and between 30°F and 80°F in
heating.
QV units can accommodate a wide range of
air temperatures, however, standard QV
models should not be used for 100%
outside air without consulting the factory
applications group. 100% outside air
routinely requires higher levels of
dehumidification than is available from
equipment designed for return air
applications.
NOTICE: QV units are designed and rated
for indoor installation only.

Do not install QV units in environments that fall
below freezing or exceed 100°F ambient. QV
cabinets are constructed of heavy-gauge
galvanized steel and will resist most common
types of corrosion but avoid installations in high-salt
concentration or highly-corrosive environments.
QV series units are offered with a wide range of
factory-installed options including: internal 2-way
valves; DuoGuard™ air coils; 2"4-sided filter racks;
MERV 13 filters (with constant airflow ECM
motors); on-board DDC controls; copper or
cupro-nickel water coils; water-side economizers,
and more refer to the unit model number for
installed options. See the Options section on page
#33.
On-board safety features will protect the
major unit components from damage.
