Installation and Operations Manual
Pre-Installation Steps
1.
Compare the electrical data on the unit nameplate with
packing slip and ordering information to verify that the
correct unit has been shipped.
2. Inspect all electrical connections
and wires. Connections must be clean and tight at the
terminals, and wires should not touch any sharp edges or
copper pipe.
3.
Verify that all refrigerant tubing is free of dents and
kinks. Refrigerant tubing should not be touching other
unit components.
4.
Before unit start-up, read all manuals and become
familiar with unit components and operation. Thoroughly
check the unit before operating.
Components
Master Contactor:
Energizes Compressor and optional
Hydronic Pump and/or Desuperheater pump package.
Logic Board:
Logic Board operates the compressor and
protects unit by locking out when safety switches are
engaged. It also provides fault indicator(s).
Terminal Strip:
Provides connection to the thermostat or
other accessories to the low voltage circuit.
Transformer:
Converts incoming (source) voltage to 24V AC.
Low Voltage Breaker:
Attached directly to transformer,
protects the transformer and low voltage circuit.
Reversing Valve:
Controls the cycle of the refrigerant system
(heating or cooling). Energized in cooling mode.
High Pressure Switch:
Protects the refrigerant system from
high refrigerant pressure, by locking unit out if pressure
exceeds setting.
Low Pressure Switch:
Protects the refrigerant system from
low suction pressure, if suction pressure falls below setting.
Flow Switch (Freeze Protection Device):
Protects the water
heat exchanger from freezing, by shutting down compressor
if water flow decreases.
Compressor (Copeland Scroll):
Pumps refrigerant through the
heat exchangers and pressurizes the refrigerant, which
increases the temperature of the refrigerant.

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

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.
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.
⚠
CAUTION
⚠
BEFORE DRILLING OR DRIVING ANY SCREWS INTO
CABINET, CHECK TO BE SURE THE SCREW WILL NOT
HIT ANY INTERNAL PARTS OR REFRIGERANT LINES.
