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

Equipment Installation
Special care should be taken in locating the unit. All units
should be placed on a formed plastic air pad, or a high
density, closed cell polystyrene pad slightly larger than the
base of 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�
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.
