General Description
3 General Description
The CF 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
Refriger
ation Institute (AHRI) to AHRI/ANSI/ASHRAE/ISO
standard 13256-1 for water-to-air and brine-to-air heat pumps
at Water Loop Heat Pump, Ground Loop Heat Pump, and Ground
Water Heat Pump application points. All CF Water-to-Air Heat
Pumps conform to UL 60335-2-40 by Intertek-ETL.
CF series units are available in three basic configurations:
Vertical T
op-Supply Air (VT), Horizontal End-Supply Air or
Straight-Through Supply Air (HZ), and CounterFlow Bottom-
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 additional parts required.
CF units can accommodate a wide range of air temperatures,
however, standard CF models should not be used for 100%
outside air without consulting with Engineering Applications
(EAP). 100% outside air routinely requires higher levels of
dehumidification than is available from equipment designed
for return air applications.
NOTICE
CF units are designed and rated for conditioned space
installation only.
NOTICE
DO NOT install CF units in environments that fall below
freezing or exceed 100°F ambient.
NOTICE
CF cabinets are constructed of heavy-gauge galvanized steel
and will resist most common types of corrosion but avoid
installations in high-salt concentration or highly-corrosive
environments.
CF series units are offered with a wide range of factory-installed
options including: internal 2-way valves; DuoGuard™ 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. See the Options section
on page #36.
On-board safety features will protect the major unit
components from damage.
