Section 3: Installation Considerations
Consumer Instructions: Dealer should instruct the consumer in proper operation,
maintenance, lter 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 qualied
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 do­it-yourselfers, but Enertech Global offers no warranty on equipment that is purchased via the internet or installed by persons without proper training.
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.
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; still 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 well-trained, qualied
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 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 xtures do not have to be removed for servicing and lter 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.
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
& 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 piping the desuperheater.

Section 3: Operation Considerations
Guidelines For Heating Mode Operation For Water-To-Water Units Using Scroll Compressors
Enertech recommends the aquastat setting not be set above 110°F for the storage tank temperature. Excessive vibration and part failure can occur at higher than recommended
temperature settings. The higher operating temperatures cause substantial efciency and
capacity reductions.
The performance is negatively affected as the unit operates at the higher water temperatures
and it benets the unit and the homeowner to operate at or below the recommended water
temperature of 110°F.
With the lower efciency created by higher water temperatures, the output capacity of the unit is decreased along with the efciency. When operating at the higher entering water temperature the heat of extraction is signicantly reduced, as well. In order to maintain the
needed capacity, more of the heat is coming from the compressor working harder to compress the refrigerant.
The illustration below shows the parameters which are safe for compressor operation. Based on the leaving load water of 120°F, the loop would have to maintain 35°F to operate within the acceptable operating conditions for the compressor. Once your loop temperatures drop below 35°F, the acceptable leaving load temperature drops below 120°F. If you are designing loops for 30°F, the recommended leaving load temperature is 110°F.
Because the water-to-water machines have become so popular for providing heated water for a multitude of uses, we’ve provided the above chart for reference.
The obvious correlation is that the warmer the Source Entering Water Temperature, the hotter the Load Leaving Water Temperature can be, to a point. R410A can only handle up to about 125°F Load Leaving Water Temperature before putting the compressor at risk.
Actual usage, and choices of heat distribution devices need to follow the acceptable operating conditions presented in the chart. If a question arises, please consult the Technical Services Department.

Section 3: Buffer Tanks
BUFFER TANKS
Virtually all water-to-water heat pumps used for hydronic applications require a buffer tank to prevent equipment short cycling, and to
allow lower ow rates through the water-to-
water unit than through the hydronic delivery system. The following are considerations for buffer tank sizing.
• The size of the buffer tank should be determined based upon the predominant use of the water-to-water equipment (heating or cooling).
• The size of the buffer tank is based upon the lowest operating stage of the equipment. For example, a water-to-water heat pump with a two-stage compressor or two
compressors may be sized for rst stage
capacity, reducing the size of the tank (two­stage aquastat required).
• Pressurized buffer tanks are sized differently than non-pressurized tanks (see guidelines listed below).
stage. Requirements for storage are less according to the manufacturer of the HSS series non-pressurized buffer tank. Using the same conditions for maximum heating and cooling capacity mentioned above, non-pressurized buffer tanks require 6 U.S. gallons per ton.
Pressurized buffer tanks for predominately heating applications should be sized at one (1) U.S. gallon per 1,000 Btuh of heating capacity (10 gallons per ton may also be used) at the maximum entering source water temperature (EST) and the minimum entering load water temperature (ELT), the point at which the water­to-water unit has the highest heating capacity, usually 50-70°F EST and 80-90°F ELT.
For predominately cooling applications, pressurized buffer tanks should be sized at one (1) U.S. gallon per 1,000 Btuh of cooling capacity (10 U.S. gallons per ton may also be used) at the minimum EST and the maximum ELT, the point at which the water-to-water unit has the highest cooling capacity, usually 50­70°F EST and 50-60°F ELT.
Select the size of the tank based upon the larger of the calculations (heating or cooling).
Non-pressurized buffer tanks must also be sized based upon predominate use (heating or cooling) and based upon the lowest capacity

Section 4: Unit Placement
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. Is there enough space for service access? A general rule of thumb is at least 2 feet in the front and 2 feet on at least one side.
2. 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 polystyrene pad. This helps eliminate vibration noise that could
be transmitted through the oor.
3.
If units are being placed on racking, the unit must be placed on a solid foundation covering the full base of the unit. Also, utilize a foam pad between the unit and the rack.
4. The installer must verify that all applicable wiring, piping, and accessories are correct and on the job site.
PRE-INSTALLATION
Before you fully install the geothermal equipment, it is recommended you go through this quick checklist before placing the equipment.
⧠ Fully inspect the unit after unpacking. ⧠
Locate the Unit Start-Up form from this manual and have it available as the unit
installation proceeds.
HYDRONIC AIR HANDLER INSTALLATION
These units have a 0” minimum clearance to
combustible materials rating from all cabinet surfaces. The unit should be i9nstalled with serviceability clearance of 30” from the front of the unit. The unit can be serviced entirely
from the front, including replacing the lter.
Be sure and route primary and secondary drain connections so as not to obstruct
replacement of lter.
UPFLOW APPLICATION
In an upow installation the discharge outlet
is at the top. Care should be taken to insure unit is level to permit proper condensate drainage.
Normal upow installation will be in a
basement or closet. If installed in a closet, the closet should have a platform framed in, with an opening on top of the platform centered in the closet. Connect the supply air outlet to a warm air plenum. Install return air grilles from outside the closet to space below the platform. Platform must be at least 10” above the
oor. If installed in a basement, run supply
and return ductwork in accordance with local codes. Caution! A “P” trap must be installed in the
coil drain line! Cap unused drain ttings.
HORIZONTAL APPLICATION
Horizontal application will normally be used in an attic or crawl space. This type of installation requires a return air duct be attached to the unit inlet. The opposite end of the return air duct is attached to a return
air lter grill through the ceiling or wall. Remove lter from unit if lter grill is used. The unit is shipped in right to left conguration.
For left to right applications (Begin with the unit in the verticl upright poisition and before connecting drains and refrigerant lines) remove coil and doors and move
horizontal pan to right side. Reinstall coil and doors. CAUTION: IT IS MANDATORY TO USE AN EMERGENCY AUXILLARY DRAIN PAN WITH ANY COIL OR AIR HANDLER INSTALLED IN AN ATTIC OR ABOVE A FINISHED CEILING!
DOWNFLOW APPLICATION
Contact Enertech for proper downow kit
including instructions.
Unit is shipped from the factory arranged to
be installed in a vertical upow or horizontal right to left airow position (standard) or eld convertible to a horizontal left to right airow
position.

Section 5: Unit Piping Installation
Open Loop Piping
Placement of the components for an open loop system are important when considering water quality and long term maintenance. The water solenoid valve should always be placed on the outlet of the heat pump, which will keep the heat exchanger under pressure when the unit is not operating. If the heat exchanger is under pressure, minerals will stay in suspension. Water solenoid valves are also designed to close against the pressure, not with the pressure. Otherwise, they tend to be noisy when closing.
A ow regulator should be placed after the
water solenoid valve. Always check the product
specication catalog for proper ow rate. A
calculation must be made to determine the
ow rate, so that the leaving water temperature
does not have the possibility of freezing.
Other necessary components include a strainer,
boiler drains for heat exchanger ushing, P/T
ports and ball valves. Ball valves allow the water to be shut off for service, and also help when velocity noise is noticeable through the
ow regulator. Spreading some of the pressure
drop across the ball valves will lessen the
velocity noise. Always double check ow rate
at the P/T ports to make sure the ball valve
adjustments have not lowered water ow too much, and essentially taken the ow regulator
out of the equation. It’s a good idea to remove the ball valve handles once the system is completed to avoid nuisance service calls.
Hose kits are optional, but make for an easier installation, since the P/T ports and connections are included. The hose also helps to isolate the heat pump from the piping system.
Since the heat pump can operate at lower
waterow on rst stage, two stage units
typically include two water solenoid valves
to save water. The ow regulators should be
sized so that when one valve is open the unit
operates at rst stage ow rate, and when
both valves are open, the unit operates at
full load ow rate. For example, a 4 ton unit needs approximately 4 GPM on rst stage, and approximately 7 GPM at full load. The ow regulator after the rst valve should be 4 GPM, and the ow regulator after the second valve
should be 3 GPM. When both valves are open, the unit will operate at 7 GPM.

Water Quality
The quality of the water used in geothermal systems is very important. In closed loop systems the dilution water (water mixed with antifreeze) must be of high quality to ensure adequate corrosion protection. Water of poor quality
contains ions that make the uid “hard” and
corrosive. Calcium and magnesium hardness ions build up as scale on the walls of the system and reduce heat transfer. These ions may also react with the corrosion inhibitors in glycol based
heat transfer uids, causing them to precipitate
out of solution and rendering the inhibitors ineffective in protecting against corrosion. In addition, high concentrations of corrosive ions, such as chloride and sulfate, will eat through any protective layer that the corrosion inhibitors form on the walls of the system.
Ideally, de-ionized water should be used for dilution with antifreeze solutions since de-
ionizing removes both corrosive and hardness ions. Distilled water and zeolite softened water are also acceptable. Softened water, although free of hardness ions, may actually have increased concentrations of corrosive ions and, therefore, its quality must be monitored. It is recommended that dilution water contain less than 100 PPM calcium carbonate or less than 25 PPM calcium plus magnesium ions; and less than 25 PPM chloride or sulfate ions.
In an open loop system the water quality is of no less importance. Due to the inherent variation of the supply water, it should be tested prior to making the decision to use an open loop system. Scaling of the heat exchanger and corrosion of the internal parts are two of the potential problems. The Department of Natural Resources or your local municipality can direct you to the proper testing agency. Please see Table 1 for guidelines.

Interior Piping
All interior piping must be sized for proper ow
rates and pressure loss. Insulation should be used on all inside piping when minimum loop temperatures are expected to be less than 50°F. Use the table below for insulation sizes with different pipe sizes. All pipe insulation should be a closed cell and have a minimum wall thickness of 3/8”. All piping insulation should be glued and sealed to prevent condensation and dripping. Interior piping may consist of the following materials: HDPE, copper, brass, or rubber hose (hose kit only). PVC is not allowed
on pressurized systems.

Typical Pressurized Flow Center Installation
The ow centers are insulated and contain all ushing and circulation connections for
residential and light commercial earth loops
that require a ow rate of no more than 20 gpm. 1-1/4” fusion x 1” double o-ring ttings
(AGA6PES) are furnished with the double
o-ring ow centers for HDPE loop constructions. Various ttings are available for the double o-ring ow centers for different connections. See gure 2 for connection options. A typical
installation will require the use of a hose kit. Matching hose kits come with double o-ring adapters to transition to 1” hose connection.
Note: Threaded ow centers all have 1” FPT connections. Matching hose kits come with the AGBA55 adapter needed to transition from 1” FPT to 1” hose.

Typical Non-Pressurized Flow Center Installation
Standing column ow centers are designed to
operate with no static pressure on the earth loop. The design is such that the column of
water in the ow center is enough pressure to
prime the pumps for proper system operation
and pump reliability. The ow center does have
a cap/seal, so it is still a closed system, where the
uid will not evaporate. If the earth loop header
is external, the loop system will still need to be
ushed with a purge cart. The non-pressurized ow center needs to be isolated from the ush cart during ushing because the ow center
is not designed to handle pressure. Since this is a non-pressurized system, the interior piping can incorporate all the above-mentioned pipe material options (see interior piping), including
PVC. The ow center can be mounted to the
wall with the included bracket or mounted on
the oor as long as it is properly supported.

Section 6: Antifreeze
Antifreeze Overview
In areas where minimum entering loop temperatures drop below 40°F, or where piping will be routed through areas subject to freezing, antifreeze is required. Alcohols and glycols are commonly used as antifreeze. However, local and state/provincial codes supersede any instructions in this document. The system needs antifreeze to protect the coaxial heat exchanger from freezing and rupturing. Freeze protection should be maintained to 15°F below the lowest expected entering loop temperature. For example, if 30°F is the minimum expected entering loop temperature, the leaving loop temperature could be 22 to 25°F. Freeze protection should be set at 15°F (30-15 = 15°F). To determine antifreeze requirements, calculate how much volume the system holds. Then, calculate how much antifreeze will be needed by determining the percentage of antifreeze required for proper freeze protection. See Tables 3a and 3b for volumes and percentages. The freeze protection should be checked during installation using the proper hydrometer
to measure the specic gravity and freeze
protection level of the solution.
Antifreeze Characteristics
Selection of the antifreeze solution for closed loop systems require the consideration of many important factors, which have long-term implications on the performance and life of the equipment. Each area of concern leads to a different “best choice” of antifreeze. There is no “perfect” antifreeze. Some of the factors to consider are as follows (Brine = antifreeze solution including water):
Safety: The toxicity and ammability of the brine
(especially in a pure form).
Cost: Prices vary widely.
Convenience: Is the antifreeze available and
easy to transport and install?
Codes: Will the brine meet local and state/ provincial codes?
The following are some general observations about the types of brines presently being used:
Methanol: Wood grain alcohol that is considered toxic in pure form. It has good heat transfer, low viscosity, is non-corrosive, and is mid to low price. The biggest down side is that it is
ammable in concentrations greater than 25%.
Ethanol: Grain alcohol, which by the ATF (Alcohol, Tobacco, Firearms) department of the U.S. government, is required to be
denatured and rendered unt to drink. It has
good heat transfer, mid to high price, is non­corrosive, non-toxic even in its pure form, and
has medium viscosity. It also is ammable with
concentrations greater than 25%. Note that the brand of ethanol is very important. Make sure it has been formulated for the geothermal industry. Some of the denaturants are not compatible with HDPE pipe (for example, solutions denatured with gasoline).
Propylene Glycol: Non-toxic, non-corrosive, mid to high price, poor heat transfer, high viscosity when cold, and can introduce micro air bubbles when adding to the system. It has also been known to form a “slime-type” coating inside the pipe. Food grade glycol is recommended because some of the other types have certain inhibitors that react poorly with geothermal systems. A 25% brine solution is a minimum required by glycol manufacturers, so that bacteria does not start to form.
Ethylene Glycol: Considered toxic and is not recommended for use in earth loop applications.
Thermal Performance: The heat transfer and viscosity effect of the brine.
Corrosiveness: The brine must be compatible with the system materials.
Stability: Will the brine require periodic change out or maintenance?
Enertech Global WT Models, Rev.: B
GS4 (POTASSIUM ACETATE): Considered highly corrosive (especially if air is present in the system) and has a very low surface tension, which causes leaks through most mechanical
ttings. This brine is not recommended for use in
earth loop applications.

Antifreeze Charging
Calculate the total amount of pipe in the system and use Table 3a to calculate the
amount of volume for each specic section of
the system. Add the entire volume together, and multiply that volume by the proper antifreeze percentage needed (Table 3b) for the freeze protection required in your area. Then, double check calculations during installation with the proper hydrometer and
specic gravity chart (Figure 6) to determine if
the correct amount of antifreeze was added.

Section 7: Desuperheater Installation
Desuperheater Installation
Units that ship with the desuperheater function must be connected to the water heater/ storage tank with the optionally offered Desuperheater Connection Kit or (as supplied by others) shown on the following sections of this manual.
Note: Desuperheater capacity is based on 0.4 GPM Flow per nominal ton at 90°F entering hot water temperature.
Note: Units that are shipped with a desuperheater do not have the desuperheater pump wires connected to the electrical circuit, to prevent accidentally running the pump while dry. Pump has to be connected to the electric circuit (master contactor) when the lines from the water heater are installed & air is removed.

NOTE: All plumbing and piping connections must comply with local plumbing codes.
TIP: Measure the distance above the oor or
shelf that the water heater is setting on, to where the drain valve is located. This distance must be greater than one-half the width of the tee you’re about to install, or you won’t be able to thread the tee on to the water heater.
1. Disconnect electricity to water heater.
2. Turn off water supply to water heater.
3. Drain water heater. Open pressure relief valve.
4. Remove drain valve and tting from water
heater.
5. Thread the ¾” MPT x 3-1/2” nipple into the
water heater drain port. Use Teon tape, or
pipe dope on threads.
6. Thread the center port of the ¾” brass tee to the other end of the nipple.
7. Thread one of the copper adaptors into the end of the tee closest to the heat pump.
8. Thread the drain valve into the other end of the nipple. See Figure 1.
9. Above the water heater, cut the incoming cold water line. Remove a section of that line to enable the placement of the copper tee.
⚠ WARNING ⚠
TO AVOID SERIOUS INJURY, IT IS
RECOMMENDED THAT AN ANTI-SCALD
MIXING VALVE IS INSTALLED ON THE HOT WATER SUPPLY LINE INTO THE HOME. EVEN THOUGH HOT WATER TANK TEMPERATURES
COULD APPEAR TO BE SET AT LOWER
LEVELS, HIGH TEMPERATURE WATER FROM
THE DESUPERHEATER COULD RAISE TANK
TEMPERATURES TO UNSAFE LEVELS.
10. Insert the copper tee in the cold water line. See Figure 2.
11. Thread the remaining two ½”SWT x ¾”MPT
copper adaptors into the ¾” FPT ttings on
the heat pump, marked HWG IN and HWG OUT.
12. Run interconnecting ½” copper pipe from the HOT WATER OUT on the heat pump, to the copper adaptor located on the tee at the bottom of the water heater.
13. Run interconnecting ½” copper pipe from the HOT WATER IN on the heat pump, to the copper tee in the cold water line.

Section 8: Controls
MICROPROCESSOR FEATURES AND OPERATION
Enertech Global geothermal heat pump controls provide a unique modular approach for controlling heat pump operation. The control system uses one, two, or three printed circuit boards, depending upon the features
of a particular unit. This approach simplies
installation and troubleshooting, and eliminates features that are not applicable for some units.
A microprocessor-based printed circuit board controls the inputs to the unit as well as outputs for status mode, faults, and diagnostics. A status LED and an LED for each fault is provided for diagnostics.
Removable low voltage terminal strips provide
all necessary terminals for eld connections.
Not only are the thermostat inputs included, but there are also removable terminal strips for all of the accessory wiring for ease of installation and troubleshooting.
Startup/Random Start
The unit will not operate until all the inputs and safety controls are checked for normal
conditions. At rst power-up, the compressor is energized after a ve minute delay. In addition,
a zero to sixty second random start delay is
added at rst power-up to avoid multiple units
from being energized at the same time.
Short Cycle Protection A built-in ve minute anti-short cycle timer provides short cycle protection of the compressor.
Component Sequencing Delays
Components are sequenced and delayed for optimum space conditioning performance and to make any startup noise less noticeable.
Test Mode The microprocessor control allows the technician to shorten most timing delays for faster diagnostics by changing the position of a jumper located on the lockout board.
Water Solenoid Valve Connections
Two accessory relay outputs at the terminal
strip provide a eld connection for two types
of water solenoid valves, a standard 24VAC
solenoid valve, or a 24VAC solenoid valve
with an end switch. Additional eld wiring is no
longer required for operation of the end switch.
Loop Pump Circuit Breakers
The loop pump(s) and desuperheater pump on single compressor units are protected by control box mounted circuit breakers for easy wiring of pumps during installation.
Dual compressor units desuperheater pump but
loop or load side pumps. All loop and load side pumps must be wired externally using relays and circuit breakers supplied by others. Circuit breakers eliminate the need to replace fuses.
Safety Controls The control receives separate signals for high
pressure, low pressure, and low water ow. Upon
a continuous 30-second measurement of the fault (immediate for high pressure), compressor operation is suspended (see Fault Retry below),
and the appropriate LED ashes. Once the unit
is locked out (see Fault Retry below), an output (terminal “L”) is made available to a fault LED at the thermostat (water-to-water unit has fault LED on the corner post).
Low Pressure: If the low pressure switch is open for 30 continuous seconds, the compressor operation will be interrupted, and the control will go into fault retry mode. At startup, the low pressure switch is not monitored for 90 seconds to avoid nuisance faults.
High Pressure: If the high pressure switch opens, the compressor operation will be interrupted, and the control will go into fault retry mode. There is no delay from the time the switch opens and the board goes into fault retry mode. There is also no delay of switch monitoring at startup.
Flow Switch: If the ow switch is open for 30
continuous seconds, the compressor operation will be interrupted, and the control will go into
fault retry mode. At startup, the ow switch
is not monitored for 30 seconds to avoid nuisance faults.
FAULT RETRY

Enertech Global WT Models, Rev.: B
26
Page 27
Section 8: Controls
All faults are retried twice before nally locking
the unit out. The fault retry feature is designed to prevent nuisance service calls. There is an anti­short cycle period between fault retries. On the third fault, the board will go into lockout mode.
Over/Under Voltage Shutdown
The lockout board protects the compressor from operating when an over/under volt­age condition exists. The control monitors secondary voltage (24VAC) to determine if an over/under voltage condition is occur­ring on the primary side of the transformer. For example, if the secondary voltage is 18VAC, the primary voltage for a 240V unit would be approximately 180V, which is below the minimum voltage (197V) recom­mended by the compressor manufacturer. Under voltage (<18VAC) causes the com­pressor to disengage and restart when the voltage returns to >20VAC. Over voltage (>31VAC) causes the compressor to disen­gage and restart when the voltage returns to <29VAC. When an O/U Voltage condition occurs, the board will initiate a fault, shut down the
compressor, and start the ve minute ASC
Table 4a: LED Identication
period. All four fault LEDs will ash (HP + LP + FS + CO) and the thermostat “Call For
Service” indicator will be illuminated. This feature is self-resetting. If voltage returns to normal range normal operation will resume if/when the ASC period is over (except if in lockout mode). If voltage is still out of range at the end of the ASC period the control will execute a Fault Retry. On the third fault within 30 minutes, the board will go into lockout mode and illuminate the “Call For Service” indicator. When normal operation is restored the four fault LED’s will stop ash­ing and the “Call For Service” indicator will turn off.
Intelligent Reset If the thermostat is powered off and back on (soft reset), the board will reset, but the last fault will be stored in memory for ease of troubleshooting. If power is interrupted to the board, the fault memory will be cleared.
Diagnostics
The lockout board includes ve LEDs (status, high pressure, low pressure, low water ow, condensate overow) for fast and simple
control board diagnosis. Below is a table showing LED function.

Hot Water Pump Control
Controls for high water temperature and low compressor discharge line temperature prevent the hot water (desuperheater) pump from operating when the leaving water temperature is above 130°F, or when the compressor discharge line is too cool to provide adequate water heating.
Lockout Board Jumper Selection
The lockout board includes three jumpers for
eld selection of various board features.
Water Solenoid Valve Delay (WSD): When the WSD jumper is installed, the “A” terminal is energized when the compressor is energized. When the jumper is removed, the “A” terminal is energized 10 seconds after the compressor. If using the Taco water solenoid valve (or a valve with an end switch), the unit terminal strip includes a means for connecting a valve of this type. The WSD jumper should be installed. If using a fast opening valve without an end switch, the jumper should be removed.

Status
Test Mode (TEST): When the TEST jumper is installed, the board operates in the normal mode. When the jumper is removed, the board operates in test mode, which speeds up all delays for easier troubleshooting. When service is complete, the jumper must be re-installed in order to make sure that the unit operates with normal sequencing delays. While test jumper is removed, the status (bottom green light) will remain off.
Over/Under Voltage Disable (O/V): When the O/V jumper is installed, the over/under voltage feature is active. When the jumper is removed, the over/under voltage feature is disabled. On rare occasions, variations in voltage will be outside the range of the over/under voltage feature, which may require removal of the jumper. However, removal of the jumper could cause the unit to run under adverse conditions, and therefore should not be removed without contacting technical services. An over/under voltage condition could cause premature component failure or damage to the unit controls. Any condition that would cause this fault must be thoroughly investigated before taking any action regarding the jumper removal. Likely causes of an over/under voltage condition

Equipment Start-Up Process
Check the following before power is applied to the equipment
Caution: Do not start-up the unit until the new structure is ready to be occupied
Electrical:
Geothermal unit high voltage
wiring is installed correctly
Geothermal unit high voltage
wiring and breaker are the correct size
Auxiliary electric heaters are
wired and installed correctly
Circulating pumps are wired and
fused (if necessary) correctly
Desuperheater pump is NOT
wired, unless piping is complete and all air is purged
Low voltage wiring is correct and
completely installed
Equipment Start-Up
1. Energize geothermal unit with
high voltage.
2. Set the thermostat to “Heat” or “Cool.” Adjust set point to energize the unit. System will energize after delays expire (typically a five minute delay).
3. Check water flow with a flow meter (non-pressurized) or pressure drop conversion (pressurized). Pressure drop tables must be used to convert the pressure drop to GPM. The pressure drop can be obtained by checking water pressure in and water pressure out at the P/T ports.
4. Check the geothermal unit’s electrical readings listed in the Unit Electrical Data table.
5. Check the source water temperature in and out at the P/T ports (use insertion probe). Allow 10 minutes of operation before recording temperature drop.
6. Calculate the heat of extraction or heat of rejection.
Plumbing:
Pipe and pump sizes are correct Air is purged from all lines Antifreeze is installed All valves are open, including
those on the flow center
Condensate is trapped and piped
to the drain
Ductwork:
Filter is installed and clean Packaging is removed from the
blower assembly
Blower turns freely Canvas connections installed on
supply plenum & return drop
7. Check the temperature difference of the load coax (water-to-water) or air coil (water-to-air). P/T ports are recommended for use on the load side, but the line temperatures can be used to check the temperature difference.
8. Change the mode of the thermostat and adjust the set point to energize the unit. Check the data in opposite mode as the previous tests. Amp draws as well as temperature differences and flow rate should be recorded.
9. Check auxiliary heat operation by adjusting the thermostat set point 5°F above the room temperature in “Heat” mode or set thermostat to “Emergency." Record voltage, amperage, and air temperature difference.

Section 10: Troubleshooting
PERFORMANCE CHECK:
Heat of Extraction(HE)/Rejection(HR) Record information on the Unit Start-up Form
Equipment should be in operation for a minimum of 10 minutes in either mode – WITH
THE HOT WATER GENERATOR TURNED OFF.
1. Determine ow rate in gallons per minute
a. Check entering water temperature b. Check entering water pressure c. Check leaving water pressure
Once this information is recorded, nd
corresponding entering water temperature
column in Specication Manual for unit.
Find pressure differential in PSI column in Spec Manual. Then read the GPM column in Spec
Manual to determine ow in GPM.
2. Check leaving water temperature of unit. FORMULA: GPM x water temp diff, x 485 (antifreeze) or 500 (fresh water) = HE or HR in BTU/HR
A 10% variance from Spec Manual is allowed. Always use the same pressure gauge & temperature measuring device.
Water ow must be in range of Specication Manual. If system has too much water ow,
performance problems should be expected

Source Water Flow Selection
Properowrateiscrucialforreliableoperationofgeothermalheat pumps.Theperformancedatashowsthreeowratesforeachentering
water temperature (EST column). The general “rule of thumb” when
selectingowratesisthefollowing:
Topowrate:Openloopsystems(1.5to2.0gpmperton) Middleowrate:Minimumclosedloopsystemowrate
(2.25 to 2.50 gpm/ton) Bottomowrate:Nominal(optimum)closedloopsystemow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ow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owrateisadequatetopreventLWTatornearfreezing
conditions. The following steps should taken in making this calculation:
DetermineminimumEST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ow
rate (GPM) and at the design Entering Load Temperature (ELT).
Calculate the temperature difference (TD) based upon the HE and GPM of the model. TD = HE / (GPM x 500). Calculate the LWT. LWT = EST - TD.
If the LWT is below 35-38°F, there is potential for freezing conditions if
theowrateorwatertemperatureislessthanidealconditions,andthe owratemustbeincreased.
Example 1:
EST = 50°F, ELT = 95°F. Model 036 Full Load, heating. Flow rate = 5 GPM. HE = 33,600 Btuh. TD = 33,600 / (5 x 500) = 13.4°F LWT = 50 - 13.4 = 36.6°F
Waterowrateshouldbeadequateundertheseconditions.
Example 2:
EST = 40°F, ELT = 95°F. Model 036 Full Load, heating. Flow rate = 5 GPM. HE = 28,700 Btuh. TD = 28,700 / (5 x 500) = 11.5°F LWT = 40 - 11.5 = 28.5°F
Waterowratemustbeincreased.
Application Notes for Performance Data
Notes:
1.DesuperheaterCapacityisbasedupon0.4GPMFlowpernominaltonat90°Fenteringhotwatertemperature.
2. Extrapolation data down to 25°F for heating and interpolation between EST & GPM data is permissible.
3. EWT (Entering Water Temperature) is also called EST (Entering Source Temperature).
4.Loadowrateisthesameasthenominalsourceowrate,approximately3GPMperton.
