Unit Protection

Protect units from damage and contamination due to plastering (spraying), painting and all other foreign materials that may be used at the job site. Keep all units covered on the job site with either the original packaging or

Pre-Installation

Special care should be taken in locating the geothermal unit. Installation location chosen should include adequate service clearance around 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. If units are being placed on racking, the unit must be placed on a solid foundation. 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 xtures do not have to be removed for servicing and lter replacement.

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.

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.

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.

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

do not protect the

Enertech Global WT Models, Rev.: B

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.

include power company transformer selection,

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

Thermostat Wiring / Fan Speed Notes

For two-stage thermostats, use both Y1 and Y2. For single stage thermostats, jumper Y1 and Y2, and use the “CFM Y2” column in table 6b for determining jumper location. The ECM control board in the air handler is the thermostat connection point. Wire nut the thermostat wiring to the leads connected to the 1/4” spades on the ECM board.

For dehumidication in cooling, cut the resistor

at the “DEHUMIDIFY” LED. Use either the HUM terminal (reverse logic -- designed to be used with a humidistat) to lower the fan speed when

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.

Page 42

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.
