LV Heat Pump Series
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.
All 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.
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 50°F and 110°F in cooling and between 20°F
and 80°F in heating. LV units can accommodate 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 dehumidification
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
counter flow 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 refer to the unit model number for installed
options..
Note that some options are offered in limited sizes
and/or voltages.
On board safety features will protect the major unit
components from damage under most foreseeable
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.
NOTICE: Never lift or move units by filter
racks, external piping or attached options/
accessories.
NOTICE: Never stack units when
transporting them.
NOTICE: When storing units:
Do not stack units larger than 6 tons
capacity!
Do not stack vertical or counter flow units
under 6 tons capacity more than 2 high
Do not stack horizontal units 6 tons capacity
more than 3 high
INSTALLATION
Step 1- Check Job Site
Installation, operation and maintenance instructions are
provided with each unit. Before unit start-up, read all
manuals and become familiar with unit and its operation.
Thoroughly check out the system before operation.
Complete the inspections and instructions listed below
to prepare a unit for installation.
Horizontal Units
LV units are designed for indoor installation only. Be
sure to allow adequate space around the unit for
servicing.
Vertical Counter flow Units
LV Units are designed for indoor installations only.
While vertical units are typically installed in a floor-level
closet or a small mechanical room, the unit access
guidelines for these units are very similar to those
described for horizontal units.
Step 2- Check Unit
Upon receipt of shipment at the job site, carefully check
the shipment against the bill of landing. Make sure all
units have been received. Inspect each unit for damage.
Ensure the shipping company makes proper notation of
any shortages or damage on all copies of the freight bill.
Concealed damage not discovered during unloading
must be reported to the shipping company.
Please inspect the product carefully for any defects or
discrepancies.
Should you identify any issue, contact the Bosch
Wholesaler / Distributor you purchased the unit from.
