GENERAL DESCRIPTION

SM 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 SM 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.

SM Series Water-to-Air Heat Pumps are available in

Vertical (VT), Horizontal (HZ) and Counter-Flow

(CF) configurations. VT units are field convertible

for three discharge/supply air orientations and

left-hand (LH) or right-hand (RH) return

configurations. HZ units have two field

configurable discharge/supply air orientations.

Several factory installed options are available: Hot

Gas Reheat, Electric Heat, Heat Recovery Package,

Sound Package, Soft Start, Constant Airflow

Blower Motor, DPS Water Flow Proving Switch,

Auxiliary Pump Relay, and Comfort Alert Module.

Electric Heat is also available as field installed

accessory. See Pg#35 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

externally mounted LCD error code display,

allowing unit diagnosis without opening the

cabinet.

Basic Horizontal unit layout and connections are

shown in Figure #3 . Refer to Dimensional

Drawings for further detail, as well as Vertical and

Counter Flow unit details. Pg#91 through Pg#95

50° Minimum Entering Water Temperature

(EWT) is recommended 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.
