TYPICAL INSTALLATION APPLICATIONS
Compressor, Blower and A Coil Sections stack
vertically for upflow and counterflow
installations. Blower and A Coil Sections can
be remotely mounted in attics or crawl spaces
providing horizontal right or left opportunities.
Steel Cabinet:
Galvanized 20 gauge zinc coated steel
cabinet with baked-on, textured enamel
which allows it to withstand 1000 hours of
salt spray exposure.
Multi-Capacity Two-Stage:
Simple thermostatic control seamlessly
stages the compressor and indoor airflow
rate between full and part load capacity
operation without cycling the compressor.
This helps to maximize comfort, humidity
control, energy efficiency and overall
reduction in compressor cycling for
improved system life.
Step Capacity Compressor:
Copeland step-capacity (2-stage) scroll
compressors are designed for increased
efficiency, quieter operation and improved
reliability for longer life.
R-410A Refrigerant:
Designed with R-410A (HFC) non-ozone
depleting refrigerant in compliance with the
Montreal protocol and 2010 EPA requirements.
Liquid Line Drier:
Protects system against moisture.
Thermostatic Expansion Valve:
For wide range refrigerant control
(2-way operation).
High Pressure Switch:
Provides additional protection for the system.
Low Pressure Switch:
Two switches provided. Factory wired
switch is for ground water applications,
alternate switch is field connected for
ground loop applications.
Control Panel:
Mid-level for easy access. Blower section
includes transformer and blower control.
High Efficiency Coaxial Water Coil in
either Copper or Cupronickel
Water to refrigerant coil is completely
insulated to prevent frost build-up at low
temperature operation.
The Bard Geo-Trio™ Geothermal/Water Source
Heat Pump delivers economical year-round
comfort by utilizing nature’s most abundant and
efficient solar energy collector – the earth. The
Geo-Trio™ Series heat pumps are designed for
low water flow rates and offer cooling efficiencies
up to 29.1 EER and heating efficiencies up to 4.8
COP on ground water, and cooling efficiencies up
to 24.9 EER and heating efficiencies up to 4.4
COP on ground loop.
All units are shipped prewired for fast, easy
installation in residential or commercial buildings.
Engineered Features
Indoor Air Coil:
Grooved copper tubing and enhanced
louvered aluminum fin for maximum heat
transfer and energy efficiency.
Coil coating is black E-Coat electrostatic
coating on complete coil.
Cased Indoor Air Coils for Fossil Fuel
(Dual Fuel):
Insulated cased coils to fit standard 17.5"
and 21" width furnaces.
Lockout Circuit:
Built-in lockout circuit resets from the room
thermostat. Provides commercial quality
protection to the compressor.
Variable Speed ECM Blower Motor:
High Efficiency
Soft starting - low noise on start up
Continuous fan - will operate at 50%
of rated Stage 2 airflow
Mild Weather Operation:
Part Load Cooling Operation will operate at
20% reduced airflow for the first 5 minutes
of operation. This results in 32% increased
applied moisture removal during this 5-
minute period, and helps humidity control
during short-run conditions. This is
seamlessly controlled internal of the unit
controls with no required user intervention.
Water Connections:
All water connections on outside of
cabinet. Brass full swivel double o-ring
connection with 1" full flow ports.
Refrigerant Connections:
Special self-sealing fittings are used with 3'
line set for stacked upflow or downflow
applications, and line sets up to 50'
available for horizontal or dual-fuel
applications.
Service Access Ports:
Permits service pressure check of
discharge and suction pressures.
Filter Rack (Optional):
Accessory kit with 1" filter (reversible for left or
right side access for upflow installations).
Accessory Electric Duct Heater Option:
5, 10, 15 and 20KW nominal size. Field
installed external to unit. For upflow and
horizontal duct installation only.
Optional Accessories:
Room thermostat - Water accessory kit -
Waterflow controls.
Domestic Hot Water Heat Exchanger System:
Double wall vented heat exchanger and pump
with ECM motor and operating controls,
factory installed on all 1-phase models.
Hot Water Heating Performance and
Operating Cost Savings: The actual amount
of hot water (gallons of hot water per day)
generated and resultant operating cost
savings can vary greatly because of several
factors: heat pump system size, hours per day
of operation of the heat pump, mode of
operation (cooling vs. heating), hot water
usage patterns, heat pump water supply
system (ground water, ground or pond loop,
etc.), and climatic conditions. The gallons of
hot water per day are dependent upon the
above variables, and in general can range up
to 125 gallons per day for a nominal 24,000
BTU heat pump system, and up to 375
gallons per day for a nominal 60,000 BTU
heat pump system in the cooling mode,
offering a 100% energy savings over
conventional electric water heaters. During
the winter months when the heat pump is
operating in the heating mode, less hot water
is available, but at the same time, the electric
water heater will consume less electricity.
