General Description
SM Split 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 UL 1995
standard and are certified to CAN/CSA C22.1 No
236 by Intertek-ETL.
Split system heat pumps consist of two
independently installed sections allowing for
centralized air distribution while remotely locating
the section containing the compressor and
water-to-refrigerant heat exchanger (Coax Water
Coil).
In the cooling mode, the air coil in the air handler
section serves as an evaporator and the water-to-
refrigerant heat exchanger serves as a condenser.
In the heating mode, their roles are reversed.
In cooling mode, the refrigerant lines connecting
the two sections consist of one line carrying liquid
refrigerant and another carrying refrigerant vapor.
The liquid carrying line will be referred to as the
liquid line while the vapor carrying line will be
referred to as the suction line.

The Water-to-Air Heat Pumps are designed to
operate with entering fluid temperature between
20°F to 80°F in the heating mode and between
50°F to 110°F in the cooling mode.
