Section 1: Introduction and General Information
Pre-Installation
Components
Special care should be taken in locating the
geothermal unit. Installation location chosen should
include adequate service clearance around the unit.
All compressor bearing 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. Flex connectors should also be installed in
between the ductwork and the air handling unit. All
units should be located in an indoor area where 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.
Master Contactor energizes compressor and
optional hydronic pump and/or desuperheater pump
package.
Pre-Installation Steps
Low Voltage Circuit Breaker attached directly to
the transformer, protects the transformer and low
voltage circuit.
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.
1. Compare the electrical data on the unit nameplate
with packing slip and ordering information to verify
that the correct unit has been shipped.
Reversing Valve controls the cycle of the
refrigerant system (heating or cooling), Energized in
cooling mode.
2. Open both, compressor and blower sections and
remove any packaging material or documentation
included in the units. At this time you can remove
any packaging used to support or hold the blower
during shipping. Remove and discard the blower
motor shaft shipping bracket from the rear of the
blower.
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.
3. 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 pipes.
Flow Switch (Freeze Protection Device) protects
the water heat exchanger from freezing by shutting
down the compressor if water flow decreases. (Not
installed in all units)
4. Verify that all refrigerant tubing is free of dents
and kinks. Refrigerant tubing should not be touching
other unit components.
Compressor pumps refrigerant through the heat
exchangers and pressurizes the refrigerant, which
increases the temperature of the refrigerant.
5. Before unit start-up, read all manuals and
become familiar with unit components and
operation. Thoroughly check the unit before
operating.
⚠ CAUTION ⚠
ALL 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 CERTIFIED
FOR OUTDOOR APPLICATIONS.
SUCH INSTALLATION WILL VOID ALL
WARRANTIES.

Section 2: Installation Considerations
Consumer Instructions
Electrical
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.
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.
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 qualified
technicians should install an Enertech Global built
geothermal system.
Looping 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.
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.
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.
Enertech Global has set forth this policy to ensure
installations of Enertech Global geothermal systems
are done safely and properly. The use of welltrained, qualified technicians helps ensure that
your system provides many years of comfort and
savings.
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.
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 flow 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 fixtures
do not have to be removed for servicing and filter
replacement.
Enertech Global, LLC
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 piping
the desuperheater.

Section 2: Installation Considerations
Duct Work
Unit Placement
All new ductwork shall be designed as outlined in
the Sheet Metal and Air Conditioning Contractors
National Association (SMACNA) or Air Conditioning
Contractors of America (ACCA) or American Society
of Heating, Refrigerating and Air Conditioning
Engineers (ASHRAE) handbooks.
When installing a geothermal heating and cooling
unit, there are several items the installer should
consider before placing the equipment.
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 in
the front and air coil sides depending on return
ductwork size.
All supply/return plenums should be isolated
from the unit by a flexible connector (canvas) or
equivalent to prevent transfer of vibration noise
to the ductwork. The flex connector should be
designed so as not to restrict airflow. Turning
vanes should be used on any transition with airflow
over 500 CFM. All metal ductwork should be
insulated on the inside to prevent heat loss/
gain, condensation and to absorb air noise. If
the unit is being installed with existing ductwork, the
ductwork must be designed to handle the air volume
required by the unit being installed. When running a
cooling or heating load on a building; size ductwork
accordingly to the building design load and heat
pump CFM.
Unit Air Pad
All geothermal heating and cooling equipment
should be placed on either, a formed plastic air
pad, or a high density, closed cell polyethylene
pad. Down flow units should be placed on a noncombustible base. This helps eliminate vibration
noise that could be transmitted through the floor.
The use of corner pads alone is not recommended.
Review
The installer has verified that all applicable wiring,
ductwork, piping, and accessories are correct and
on the job site.
Industry Standard
When sizing ductwork use 400 CFM per Ton.
As a general rule, maximum recommended face
velocity for a supply outlet used in a residential
application is 750 FPM. Maximum recommended
return grille velocity is 600 FPM. Systems with
higher velocities are likely to have noise problems.
Unit Orientation
Configure left or right side return and discharge air
pattern prior to air handler unit installation.
In buildings where ceilings are 8 feet or more, at
least 50 percent of the return air should be taken
back to the heat pump from the ceiling or high
sidewall location and not more than 50 percent from
the floor or low sidewall location.

Notes:
1. All line and low voltage wiring must adhere to the National Electrical Code and local codes, whichever is the most
stringent.
2. In determining the correct supply wire size and maximum length, reference NFPA 70, Section 310. If the calculation is
close to the maximum allowable ampacity of a particular wire size, use the next size up. This will ensure that no adverse
effects occur, such as light dimming and/or shortened compressor life.
3. All fuses class RK-5.
4. Min/Max Voltage: 208/230/60 = 187-252
*The external loop pump FLA is based on a maximum of three UP26-116F-230V pumps (1/2hp) for 048-072 and two pumps
for 018-036.

Notes:
1. Dehumidification mode can be enabled by cutting the jumper on the ECM board. When cut, cooling CFM is reduced by 15%, and heating/ auxiliary heat CFM remains unchanged. Example: Model 036 with HEAT and COOL jumpers on C setting and ADJUST jumper on Norm setting would run at 1115 CFM with jumper cut, instead of 1310 CFM with jumper intact.
2. Gray shaded areas are recommended settings. Other settings may be used, depending upon application. DO NOT cut dehumidification jumper if CFM setting will cause airflow to be below 250 CFM per ton on first stage, and below 325 CFM per ton on second stage. Example: Model 036 should not run below 750 CFM in frist stage, or below 975 CFM in second stage. 3. The COOL and HEAT jumpers should both be set at the same position. COOL controls heating and cooling airflow; HEAT controls electric heat airflow.
4. Above CFM will be maintained up to 0.50" ESP for models MPD024 and 036, and up to 0.75" ESP for models MPD048 and 060.

Section 6: Water Flow Calculations and Selection
Water Flow Calculations and Selection
Proper flow rate is crucial for reliable operation
of geothermal heat pumps. The performance
data shows three flow rates for each entering
water temperature (EWT column). The general
“rule of thumb” when selecting flow rates is the
following:
Top flow rate: Open loop systems (1.5 to 2.0
gpm per ton)
Middle flow rate: Minimum closed loop system
flow rate (2.25 to 2.50 gpm/ton)
Bottom flow rate: Nominal (optimum) closed
loop system flow rate
(3.0 gpm/ton)
Although the “rule of thumb” is adequate in
most areas of North America, it is important to
consider the application type before applying
this “rule of thumb.” Antifreeze is generally
required for all closed loop (geothermal)
applications. Extreme Southern U.S. locations
are the only exception. Open loop (well
water) systems cannot use antifreeze, and
must have enough flow rate in order to avoid
freezing conditions at the Leaving Source Water
Temperature (LWT) connection.
Calculations must be made for all systems
without antifreeze to determine if the top flow
rate is adequate to prevent LWT at or near
freezing conditions. The following steps should
taken in making this calculation:
Determine minimum EWT based upon your
geographical area.
Go to the performance data table for the heat
pump model selected and look up the the
Heat of Extraction (HE) at the “rule of thumb”
water flow rate (GPM) and at the design
Entering Air Temperature (EAT).
Example 1:
EWT = 50°F.
Model GXT048, high capacity. Flow rate = 6 GPM.
Air Flow = 1500 CFM. HE = 36,700 Btuh.
TD = 36,700 / (6 x 500) = 12.2°F
LWT = 50 - 12.2 = 37.8°F
Since the water flow is leaving at approximately
38°F, the flow rate
is acceptable.
Example 2:
EWT = 40°F.
Model GXT048, high capacity. Flow rate = 6 GPM.
Air Flow = 1500 CFM. HE = 36,700 Btuh.
TD = 36,700 / (6 x 500) = 12.2°F
LWT = 40 - 12.2 = 27.8°F
Water flow rate must be increased to avoid freezing.
Performance Data Notes:
1. Capacity data is based upon 15% (by volume)
methanol antifreeze solution.
2. Desuperheater capacity is based upon 0.2 GPM
Flow per nominal ton at 70°F entering hot water
temperature.
3. Interpolation between above categories is
permissible; extrapolation is not.
4. See Flow Rate Selection above for proper
application.
Calculate the temperature difference (TD) based
upon the HE and GPM of the model.
TD = HE / (GPM x 500).
Calculate the LWT.
LWT = EWT - TD.
If the LWT is below 35-38°F, there is potential
for freezing conditions if the flow rate or water
temperature is less than ideal conditions, and the
flow rate must be increased.
