GENERAL DESCRIPTION
The LV 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.
These units are safety listed with Intertek Test
Labs (ETL) to cUL standard 1995. These units
meet all current applicable requirements of
ASHRAE 90.1.
LV 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, LV series models can operate with entering
fluid temperatures between 40°F and 120°F in
cooling and between 20°F and 90°F in heating. LV
units can accomodate a wide range of air
temperatures, however, standard LV models
should not be used for 100% outside air without
consulting the factory applications group. 100%
outside air routinely requires higher levels of
dehumidifcation than is available from equipment
designed for return air applications.
LV series units are available in three basic
configurations: vertical top supply air (VT),
horizontal end supply air or straight through
supply air (HZ) and counterflow down supply air
(CF). 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.
LV units are designed and rated for indoor
installation only. LV units should not be installed
in environments that fall below freezing or exceed
100°F ambient. LV cabinets are constructed of
heavy gauge G-90 galvanized steel and will resist
most common types of corrosion for the life of the
equipment.
LV series units are offered with a wide range of
factory installed options including: PSC, constant
torque ECM or constant air flow ECM fan motors;
hot gas reheat; hot gas bypass; internal 2 way
valves; tin plated 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.
On board safety features will protect the major
unit components from damage under most
foreseable installation and operation problems.
MOVING AND STORAGE
If the equipment is not needed for immediate
installation upon arrival at the job site, it should be
left in its packaging and stored in a clean, dry area.
Units must be moved and stored in the normal
upright position at all times.
Use caution to avoid damage to filter racks and
duct flanges when storing or handling units.
Note that some options are offered in limited
sizes and/or voltages.
Never lift or move units by filter racks,
external piping or attached options/
accessories.
Never stack units when transporting
them.
When storing units:
Do not stack units larger than 6 tons
capacity!
Do not stack vertical or counterflow units
under 6 tons capacity more than 2 high
Do not stack horizontal units 6 tons capacity
more than 3 high
