Consumer Instructions: Dealer should instruct the
consumer in proper operation, maintenance, filter
replacements, thermostat and indicator lights. Also
provide the consumer with the manufacturer’s
Owner’s Manual for the equipment being installed.
Enertech Global D-I-Y Policy: Enertech Global’s
geothermal heat pumps and system 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 qualified technicians should install
a Enertech Global built geothermal system.
Because of the importance of proper installation,
Enertech Global does not sell equipment direct 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,
qualified 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. Downflow
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 ductwork or other
permanently installed fixtures do not have to be
removed for servicing and filter 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.
Section 3: Installation Considerations
Thermostat: Thermostats should be installed
approximately 54 inches off the floor 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 unconnected ensures
that the pump is 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 & fittings
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
desuperheater piping.
UV Light Usage: The use of a UV light in the unit return
air plenum should be such that the light does not
have a direct line of sight to the air coil of the unit.
UV lights could cause internal wiring, foam insulation,
or other components to deteriorate. It would be
better to place the UV light in the supply air plenum,
or ductwork. This also helps keep the light cleaner.
Additionally, if a humidifier is installed and in line
of the sight of the UV light, consult the humidifier
install manual for indication of whether the light will
deteriorate any parts of the humidifier (like the pad).
