Geothermal heating/cooling systems operate via sub-surface
conductive heat transfer, using the naturally renewable
temperature of the earth’s crust as a heat source in the winter,
and as a heat sink in the summer.
Within any climate zone, the
weather, and underground conditions vary from place to place.
To determine your climate zone, see

This geothermal heat pump system contains an earth loop that
includes a vapor line, an insulated liquid line, and a bottom
segment called a torpedo. See

This unit has been tested for capacity and efficiency and
will provide many years of safe and dependable comfort,
providing it is properly installed and maintained. With regular
maintenance, this unit will operate satisfactorily year after
year. Abuse, improper use, and/or improper maintenance can
shorten the life of the appliance and create unsafe hazards.
To achieve optimum performance and minimize equipment
failure, it is recommended that periodic maintenance be
performed on this unit. The ability to properly perform
maintenance on this equipment requires certain tools and
mechanical skills. See

must be calculated and a system of the proper capacity
selected.
√
Check the electrical supply and verify the power supply is
adequate for unit operation.
√
The indoor section (air handler, furnace, etc) should be
installed before routing the refrigerant tubing. Refer to the
installation instructions supplied with the air handler or
furnace.
√
All units are securely packed at the time of shipment and
upon arrival should be carefully inspected for damage prior
to installing the equipment at the job site. Claims for damage
