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
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 humidier is installed and in line
of the sight of the UV light, consult the humidier
install manual for indication of whether the light will
deteriorate any parts of the humidier (like the pad).
Unit Placement
When installing a geothermal heating and cooling
unit, there are several items the installer should
consider before placing the equipment.
1. Service Access and Installation Space. Is there
enough space for service access? A general
rule of thumb is at least 2 to 2 1/2 feet on the
front and air coil sides depending on return
ductwork size.
2. Unit Air Pad. All vertical geothermal heating
and cooling equipment should be placed
on either a formed plastic air pad, or a high
density, closed cell polyethylene pad. This
helps eliminate vibration noise that could be
transmitted through the oor.
The use of corner pads alone is not
recommended.
3. The installer has veried that all applicable
wiring, ductwork, piping, and accessories are
correct and on the job site.
4. Determine left or right side return air pattern
prior to unit assembly and installation

Consumer Instructions
Dealer should instruct the consumer in proper
operation, maintenance, 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 qualied 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,
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. Downow
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 xtures do not have to be
removed for servicing.
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.
⚠ CAUTION ⚠
This GEOTHERMAL equipment is designed for indoor
installation only. DO NOT install or store unit in
a corrosive environment or in a location where
temperature and humidity are subject to extremes.
Equipment is not certied for outdoor applications.
Such installation will void all warranties.
