GENERAL DESCRIPTION
LM Series Water-to-Air Heat Pumps provide the
best combination of performance and efficiency
available. All units are performance certified to
American Heating and Refrigeration Institute
(AHRI) ISO Standard 13256-1. All LM Water-to-Air
Heat Pumps conform to UL1995 standard and are
certified to CAN/CSA C22.1 No 236 by Intertek-
ETL.
The Water-to-Air Heat Pumps are designed to
operate with entering fluid temperature between
20°F to 90°F in the heating mode and between
30°F to 120°F in the cooling mode.
LM Series Water-to-Air Heat Pumps are available in
Vertical (VT) and Horizontal (HZ) configurations.
VT and HZ units Discharge Air Orientation is Field
Configurable with the purchase of a separate kit.
Several factory installed options are available:
Hot Gas Reheat, Electric Heat, Sound Package,
Smart Start, Constant Airflow Blower Motor, 2” 4-
sided filter racks, MERV 8 & 13 filters, Differential
Pressure Switch (DPS) Water Flow Proving Switch,
Auxiliary Pump Relay, Air Flow Proving Sensor,
Zone Valve and Internal Water Pump. See Pg#15
for more detail.
Safety devices are built into each unit to provide
the maximum system protection possible when
properly installed and maintained. Each unit has an
external LED error code display, allowing unit
diagnosis without opening the cabinet.
Basic Horizontal Unit layout and connections are
shown in Figure #2 . For more detail on both the
Vertical and Horizontal units, refer to the
Dimensional Drawings on Pg#55 through Pg#58.
50° Minimum Entering Water Temperature
(EWT) for well water applications with sufficient
water flow to prevent freezing. Antifreeze
solution is required for all closed loop
applications. Cooling Tower/Boiler and
Geothermal applications should have sufficient
antifreeze solution to protect against extreme
conditions and equipment failure. Frozen water
coils are not covered under warranty. Other
equivalent methods of temperature control are
acceptable.
