Equipment Selection
The installation of geothermal heat pump units and all
associated components, parts, and accessories which make
up the installation shall be in accordance with the regulations
of ALL authorities having jurisdiction and MUST conform to
all applicable codes. It is the responsibility of the installing
contractor to determine and comply with ALL applicable
codes and regulations.
General
Proper indoor coil selection is critical to system effi ciency.
Using an older-model coil can affect effi ciency and may
not provide the customer with rated or advertised EER
and COP. Coil design and technology have dramatically
improved operating effi ciency and capacity in the past 20
years. Homeowners using an older coil are not reaping these
cost savings and comfort benefi ts. NEVER MATCH AN R-22
INDOOR COIL WITH AN Puron® COMPRESSOR SECTION.
Newer indoor coils have a larger surface area, enhanced fi n
design, and grooved tubing. These features provide a larger
area for heat transfer, improving effi ciency and expanding
capacity. Typical older coils may only have one-third to one-
half the face area of these redesigned coils.
Indoor Coil Selection – GT-PCS (50YGS and 50YGP)
Split system heat pumps are designed for and rated in the
AHRI directory with specifi c air handlers and cased coils. GT-
PCS models are rated with FE/FV4 Air Handlers and CNP
Cased coils. Applying these heat pumps to other brands/
models of air handlers or cased coils may result in
unsatisfactory performance and make them ineligible for
the Energy Star program, utility rebates, or tax credits.

Due to limitations in combining a geothermal split unit with a
Carrier Infi nity fan coil, furnace or Infi nity Control; or a Bryant
Evolution fan coil, furnace or Evolution Control, refer to Service
Bulletins SMB 10-0007 and DSB 10-0007.
