Enertech Global D-I-Y Policy
Enertech Global’s geothermal heat pumps and
systems installations may include electrical,
refrigerant and/or water connections. Federal, state
and local codes and regulations apply to various
aspects of the installation. Improperly installed
equipment can lead to equipment failure and health/
safety concerns. For these reasons, only qualied
technicians should install an Enertech Global built
geothermal system.
Because of the importance of proper installation,
Enertech Global does not sell equipment directly to
homeowners. Internet websites and HVAC outlets
may allow for purchases directly by homeowners
and do-it-yourselfers, but Enertech Global offers
no warranty on equipment that is purchased via
the internet or installed by persons without proper
training.
Enertech Global has set forth this policy to ensure
installations of Enertech Global geothermal systems
are done safely and properly. The use of well-
trained, qualied technicians helps ensure that
your system provides many years of comfort and
savings.
Equipment Installation
Special care should be taken in locating the unit.
All vertical units should be placed on a vibration
absorbing pad (air pad) slightly larger than the base
of the unit. Down ow units should be placed on
a non-combustible base. Flex connectors should
also be installed in between the ductwork and the
unit. All units should be located in an indoor area
were the ambient temperature will remain above
55°F and should be located in a way that piping and
duct work or other permanently installed xtures
do not have to be removed for servicing and lter
replacement
Electrical
All wiring, line and low voltage, should comply with
the manufacturer's recommendations, The National
Electrical Code, and all local codes and ordinances.
Thermostat
Thermostats should be installed approximately 54
inches off the oor on an inside wall in the return air
pattern and where they are not in direct sunlight at
anytime.
Loop Pumping Modules
Must be wired to the heat pump’s electric control
box. A special entrance knockout is provided
below the thermostat entrance knockout. A pump
module connection block, connected to the master
contactor, and circuit breaker is provided to connect
the Pump Module wiring.
Desuperheater Package
Water heating is standard on all residential units
(units may be ordered without). It uses excess
heat, during both heating and cooling cycles, to
provide hot water for domestic needs. A double wall
desuperheater exchanger (coil) located between
the compressor and the reversing valve, extracts
superheated vapor to heat domestic water; while
satisfying its heating and cooling needs. The
water circulation pump comes pre-mounted in all
residential units, but must be electrically connected
to the master contactor. Leaving it disconnected
ensures that the pump will not run without a
water supply.
The Desuperheater package can make up to
60% (depending on heat pump usage) of most
domestic water needs, but a water heater is still
recommended.
Desuperheater Piping
All copper tubes & ttings should be 5/8” O.D (1/2”
nom) minimum with a maximum of 50ft separation.
Piping should be insulated with 3/8” wall closed cell
insulation.
Note: Copper is the only approved material for
piping the desuperheater.
