DANGER:

WARNING:

CAUTION:

NOTE:

Indicates the presence of immediate hazards which will cause severe personal injury, death or substantial property damage if ignored.

Indicates the presence of hazards or unsafe practices which could cause severe personal injury, death or substantial property damage if ignored.

Indicates the presence of hazards or unsafe practices which could cause minor personal injury or product or property damage if ignored.

Indicates special instructions on installation, operation, or maintenance which are important but not related to personal injury hazards.

This manual, as well as the pool/spa heat pump pool heater itself, contains ANSI-approved product safety signs and labels. Please read these signs and labels, as they convey important safety information about hazards that may be potentially present in and around the heat pump pool heater.

CAUTION: Elevated water temperature can be hazardous. The U.S. Consumer Product Safety

Commission has these guidelines:

1. Spa water temperatures should never exceed

104°F (40°C). A temperature of 100°F (38°C) is considered safe for a healthy adult. Special caution is suggested for young children.

2. Drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness which could lead to unconsciousness and subsequently result in drowning.

3. Pregnant Women Beware! Soaking in water over

102°F (39°C) can cause fetal damage during the first three months of pregnancy resulting in the birth of a brain-damaged or deformed child.

Pregnant women should stick to the 100°F (38°C) maximum rule.

4. Before entering the spa or hot tub, users should check the water temperature with an accurate thermometer; spa or hot tub thermostats may err in regulating water temperatures by as much as

4°F (2.2°C).

5. Persons with a medical history of heart disease, circulatory problems, diabetes, or blood pressure problems should obtain a physician's advice before using pools or hot tubs.

6. Persons taking medications which induce drowsiness, such as tranquilizers, antihistamines, or anticoagulants, should not use spas or hot tubs.

CAUTION: Improper chemical content in a swimming pool or spa can damage the heat pump pool heater. DO NOT add pool chemicals to the skimmer.

This will damage the heat pump pool heater and could void the heat pump pool heater warranty.

ALWAYS follow the product manufacturer’s directions when adding any chemicals to your pool.

WARNING: These heat pump pool heaters are charged with R-410A refrigerant. Ensure that all service work is done with gauges and equipment suitable for R-410A.

Introduction

WARNING: This pool/spa heat pump pool heater is an electromechanical machine that incorporates a pressurized refrigerant gas in a sealed system.

ONLY trained and qualified service personnel are authorized to install or service this equipment.

Without proper training and knowledge of such equipment, any attempt to install or service the unit could result in serious injury or even death.

Installation Considerations

WARNING: Do not install the unit within 3 ft of fossil fuel burning heaters. Air intake along the sides of this heat pump pool heater could disturb the combustion process of the unit, and could cause damage or personal injury .

• Mount the unit on a level, sturdy base, preferably a concrete slab or blocks. The size of the base should be at least 3 ft by 3 ft.

• You must install the 4 black rubber sound isolation pads (each 2 inches square) that ship with the unit. The pads are shipped in a bag with the unions, gaskets and the I&O manual. Install pads under the 4 corners of the unit to reduce vibration and sound transmission to the base.

This manual contains important information on the use, maintenance and troubleshooting of your new heat pump pool heater. This unit must be properly installed, maintained and operated for optimal performance.

This heat pump pool heater is an extremely efficient, economical machine designed specifically for swimming pool heating. It is similar in design and operation to a typical residential air conditioning system. The unit employs a hermetic motor/compressor operating in a refrigeration cycle to extract heat from ambient air and deliver it to the circulating pool water.

As with all heat pump pool heaters, compared to other types of heaters such as gas or oil-fired, this heat pump pool heater has lower heating capacity on a

BTUH/hr basis. As a result, it will be required to operate longer to accomplish the desired results. It may, at certain times, operate as much as 24 hours per day.

However, this should not be of concern to the owner, because the unit is designed to operate continuously.

Even though it may operate continuously for many hours, it will still heat the pool with greater economy than other types of fossil fuel heaters.

Place a cover or blanket over the pool at night and other non-use periods. This will keep evaporation, the cause of main heat loss, to a minimum, and will greatly reduce pool heating costs. During warmer weather, the cover may be required only at night.

CAUTION: enough to keep it completely free of standing water at all times.

Situate the heat pump pool heater carefully to minimize installation costs while providing maximum efficiency of operation, and to allow adequate service access, as follows:

• For unrestricted air intake and service access, position each side of the unit at least 1 ft (30 cm) from walls, pipes and other obstructions.

WARNING: lation;

The unit’s supporting base must be high

This unit is designed for outdoor instal-

DO NOT install it in an enclosed area such as a shed or garage.

• Recirculation of cold discharge air back into the evaporator coil will greatly reduce the unit’s heating capacity and efficiency.

• This unit features an ‘up-flow’ discharge for quiet operation. Air is pulled up through the evaporator coil and discharged through the top grill. Allow at least 5 ft (1.5 m) clearance above the unit for unrestricted air discharge. DO NOT install the unit under a porch or deck. Refer to Fig. 1.

• To minimize water piping, locate the unit as close as possible to the existing pool pump and filter.

Fig. 1: Installation Clearances

• Irrigation water should be directed away from the heat pump pool heater-water spray can damage the heat pump pool heater.

Electrical Code, NFPA No. 70, latest edition, and all applicable state and local codes. Wiring diagrams are located on pages 32 through 33.

Rain water run offs- the heat pump pool heater can withstand normal rain. Install rain gutters to prevent direct steams of rain water to the heat pump pool heater.

• It is important to keep the area next to the heat pump pool heater clear of shrubs, bushes and chemicals containers. They could prevent air from circulating fully through the heat pump pool heater, and will affect the operation of the heat pump pool heater or damage the heat pump pool heater.

• When installed in areas where freezing temperatures can be encountered, drain the water circuit to prevent possible freeze-up damage.

• Locate the equipment disconnect means within 3 feet of the heater’s electrical enclosure, or as close to the heater as possible. Always satisfy applicable codes and standards.

NOTE: Refer to the National Electrical Code, Article

680, for general requirements for swimming pools and equipment, and to Article 440 for special considerations necessary for circuits supplying hermetic refrigeration motor/compressors.

• For high wind installation requirements, refer to the diagram on page 8.

Electrical Connections

Refer to the unit rating plate below the control panel for precise power requirements for your unit, and for ampacity and over-current protection requirements.

All wiring must be in accordance with the National

• In sizing power wiring, be especially aware of upsizing requirements necessary due to wiring distances. Always satisfy applicable codes and standards.

• Electrical installation should be done by a licensed electrician only.

This unit is pre-wired to work with external control systems, heat-on-demand options and other external time clock overrides. Refer to the external control system’s instructions, and page 19 of this manual, for installation information.

Water Connections

CAUTION: The heat pump pool heater inlet and outlet connections are NOT interchangeable. They must be connected as instructed below.

1. Connect the heat pump pool heater in the return water line between the filter and the pool/spa. See the Plumbing Diagrams beginning on page 28.

2. Connect the filter outlet to the fitting marked

WATER IN at the bottom front of the unit.

3. Connect the fitting marked WATER OUT to the return piping to the pool/spa. Unit inlet/outlet connection fittings are 2-inch PVC unions.

Water connections from the unit to the main return line can be PVC pipe or flexible pipe approved for the purpose and, in either case, should be at least equal in size to the main pool/spa circulation piping.

4. In cold weather (freeze zone) areas, shutoff valves

(ball or gate type) must be installed at the unit inlet and outlet to facilitate service and cold weather drain-down.

5. Operate the pump and check the system for leaks.

6. Drain plugs are located on each union fitting as shown in Fig. 3 for draining the system during winterizing.

NOTE: While it is possible to mount the upper union with the drain plug vertically, Raypak has determined that installing both unions with the drain plugs facing down as shown in Fig. 3 provides for the best draining of the system.

CAUTION: When the drain plugs are removed for draining the system, ensure that they are stored in a safe place for re-installation when needed to restart the system.

WARNING: Install a check valve and/or a Hartford loop AFTER the heat pump pool heater and

BEFORE any chlorinating devices. Install any automatic chemical feeders AFTER the heat pump pool heater.

Improper installation of any type of automatic chemical feeders can result in serious damage to, or premature failure of, the heat pump pool heater and will void the heat pump pool heater warranty.

HPPH Control Display

The HPPH display is viewable from outside of the heater. All operation and settings of the HPPH control are accomplished through the use of the 3 buttons of the user interface. These buttons are labeled as follows:

• MENU/SET – Scroll through available menus and set changed values (MENU)

• UP – Increase values in the Adjust menu

• DOWN – Decrease values in the Adjust menu

Fig. 4: HPPH Control Display

The display uses a 2-line, 16-character backlit Liquid

Crystal Display (LCD) as the method for supplying information. The backlight is normally off. The backlight is on for 15 minutes after Power-Up and for 15 minutes after any button press. Use the LCD to setup and monitor the operation of your heater.

If the membrane switch remains inactive for 180 seconds (3 minutes), the screen will revert to the current view.

On HEAT/COOL models, the options available by pressing the MENU/SET (MENU) button are POOL

HEAT, POOL COOL, POOL AUTO, SPA, TIMED SPA and OFF. The cooling setpoint can be adjusted in the range of 50F to the Cooling Deadband value below the

Heating setpoint. This allows use in Plunge Pools.

Adjust the cooling setpoint accordingly.

The control board is equipped with a red status LED on the back of the board which flashes at a “heartbeat” of 2Hz while operating normally. The control board is also equipped with a green LED (next to the communications jack) on the back of the board which will flicker to indicate active communications when connected to another system.

Upon initial application of power, the HPPH control briefly sets all segments on the LCD at power-up. On a normal power-up, the control displays the current software revision and the model type configuration

(HEAT ONLY, POWER DEFROST or HEAT/COOL) on the LCD for 2 seconds and then resumes the user selected mode it was in before power was interrupted.

The configuration for these units should be

HEAT/COOL.

Setpoints are read from non-volatile memory. If the self diagnostic check indicates corrupted values,

“EEPROM Fault” is displayed on the LCD and operation is prohibited until setpoints are manually set.

If unit type has not been set (like during the replacement of the HPPH control), the control prompts the user to set the model type (HEAT ONLY, POWER

DEFROST, or HEAT/COOL) before any device operation is enabled. Installation in these models requires a model type of HEAT/COOL to be selected.

Upon initial installation, there are several items that must be defined and programmed depending on the configuration and accessories intended to be controlled by the HPPH control. These include: (1) 3-way valve control (Yes or No), (2) Pump control (Yes or No and then what type of control – 4-speed control or variable speed control), and (3) Auxiliary control (Yes or

No and then what type – External Heat, Auxiliary

Output or Remote Output).

Once these choices are made, then additional information relating to the establishing of pump periods, pump speeds during each period and Return/Suction

Valve positions during each period must be determined and set in the control.

The options for the control can be very simple or very detailed, depending upon each installation desires.

Once programming is completed, the control is ready for operation.

In Pool Auto mode, the cooling setpoint is the heating setpoint minus this Cooling Deadband value.

This is the temperature measured on the coil when the control goes into

Defrost mode.

If the coil temperature reaches this setpoint, Defrost will terminate. Other

Defrost algorithms are still operating behinds the scene.

The installer can program the control to Lock out operation of the unit if a specific outside temperature is measured. Off allows operation at any ambient temperature.

Set at the factory. Will need to be set by Installer during any replacement of the control board.

Set at the factory on new units.

Select “Disabled” if unit equipped with

TXV for board replacement. EXV

Type 1 is 500 step EXV. EXV Type 2 is 1600 step EXV.

This screen asks if you really want to change the EXV setting – the UP or

DOWN button must be pressed to show YES before the EXV type will be changed.

This function will shut down operation of the unit if the 24VAC signal drops below 18VAC to protect the unit from

Low Voltage. This feature can be turned off as desired.

Press and hold both the UP and

DOWN buttons for 3+ seconds to reset the factory defaults in the control. When reset, the screen will display “Defaults Set”.

NOTE: Make sure that the values for each setting are recorded for future reference or if the control ever needs to be reset to Factory Defaults. All these values will need to be re-entered.

17

Control Settings

The user can access these control settings by pressing and holding the MENU button for 5+ seconds. Any changes to values are stored into the non-volatile memory when the MENU button is pressed – which also toggles to the next setting. Failure to press any buttons for 60 seconds will cause the screen to revert back to its previous operating mode screen. However, the user mode can also be exited by pressing and holding the MENU button for 5+ seconds.

If the control is in the temporary lockbox override when the program mode is entered, the first prompt will be

“Reset PIN?”. The 2nd line will display “No”. Pressing the UP or DOWN buttons will toggle the 2nd line between “Yes” and “No”. If the MENU button is pressed while “Yes” is selected, the lockbox mode will be cleared without needing to know the original PIN.

This step will be skipped if the control is not in the temporary lockbox override mode.

Set Current Time

This allows setting of the current time. The time is followed by an “A” or “P” for AM and PM respectfully. The control has a 24-hour time clock – although it is NOT a 7-day time clock. The time clock is used for control of the pump periods.

C/F Display

This setting is used to define the units of measure for all temperature readings. Fahrenheit is the default value. You can change the setting to Celsius by toggling the UP or DOWN button and then pressing mode to lock in the change.

Spa Max Temp

This setting is used to define the maximum temperature that the control can be set at for the Spa operation. The range is 65F – 104F. The default value is 102F.

Pool Max Temp

This setting is used to define the maximum temperature that the control can be set at for the Pool operation. The range is 65F – 95F. The default value is 80F.

Pump Periods

When the Pump Operation in the Installer’s Menu is set to “4-Speed Enabled” or “Variable Enabled”, this allows the setting of Pump Periods from this menu.

When setting this parameter, the control displays

“Pump Periods” on the first line of the display. The number of pump periods (0 – 4) is displayed on the center of the 2 nd line. Pressing the UP or DOWN buttons increments/decrements the number of pump periods – factory default is 1. If a non-zero number of pump periods is selected when the MENU button is pressed, the control will prompt for On/Off times for each of the selected number of pump periods.

Temperature Control

The control uses the appropriate Pool or Spa setpoint as selected in the Operating mode. The heat demand begins when the water temperature is 0.5F or more colder (or 0.5F or more hotter in cooling mode) than the setpoint.

Additional Features

Pump Control

The control is equipped to control the system pump

(particularly if it is a Raypak VSP pump). The control provides for an output for a single speed pump (0.75A

@ 24VAC maximum) as well as an output for a variable speed pump (10mA @12 VDC). Four signals are provided for selection of 4 discrete speeds for a variable speed pump. The control can be configured to provide a PWM signal on the speed1 output. The control will energize the pump at the requested speed for each of the pump periods set in the program mode. If a heat pump demand is present during a scheduled pump operation, the pump runs at the override speed

(Speed 1) regardless of the scheduled speed. When the pump is active because of scheduled operation and there is no active heat demand, the control sets the 3-ways valve outputs to the states set in the program mode schedule.

Low Ambient (Outside) Lockout

The control is equipped with a Low Ambient Lockout feature which will prevent the start of a new cycle if the ambient temperature is lower than the programmed value. This feature is accessed through the

Installer/Service Sub-menu as noted in Table D, page

17. The default value is “OFF”, but the temperature can be adjusted between 30F and 50F. This feature can be enabled if it is desired to not operate the unit if the temperature falls below this value. NOTE: This feature will NOT stop the operation of an existing cycle, it will only prevent operation of a new cycle.

An open outdoor temperature sensor (display will read

“Air Temp -46F”) will trigger an “Outside Lockout” error if the Low Ambient lockout is enabled. An open or shorted (display will read “Air Temp 282F”) outdoor temperature sensor will also cause the control to shut off the compressor regardless of if the Low Ambient lockout is enabled.

18

Control Lock Box Mode

The control is equipped with a Control Lockout feature which is accessed by pressing and holding the MENU and DOWN buttons for 5 seconds. The user will be prompted to enter a 3-digit code. A cursor flashes under each digit in the 3 digit code when that digit is being set. Pressing the UP or DOWN buttons increases or decreases the value and press the MENU button to lock in that value. The cursor moves to the next digit for setting. Once the last digit is selected (pressing

MENU) the display will ask to confirm the established

Lockout code. Pressing UP or DOWN until “YES” is shown and then press the MENU button to confirm this

Lockout code. NOTE: Record this Lockout code for future reference.

Pressing any button when the control is in Lockout

Mode will prompt the user for the Lockout code. The display will read “Control Lockout – Enter PIN 000”. If the PIN is entered incorrectly, the display will show

“Invalid PIN”. Pressing any button will return the user to the lockout code screen.

Entering the correct Lockout code will result in the display showing “Lockout Cleared” and the display will go to the current operating state of the unit.

AUX Mode

The control has the capability to control two auxiliary outputs for various external uses (rating is 0.75A @

24VAC max.). There are 4 selectable modes within the Installer/Service Sub-menu for auxiliary mode control. These include: AUX OFF (default), AUX

OUTPUT, REMOTE OUT, and EXT HEAT. The control allows setting ON and OFF times for these 2 auxiliary outputs in the Installer/Service Sub-menu.

1. AUX OUTPUT – When AUX OUTPUT is selected, the AUX1 and AUX2 outputs turn ON/OFF from the time schedule loaded into the control at installation. Time schedules for each output are independent of each other. If the OFF time is before the ON time, the control will assume the

Aux output is to be energized over midnight. If the time of day is not known due to a clock failure, the

AUX output schedules are not run.

2. REMOTE OUT – When REMOTE OUT is selected, the AUX1 output is used to control another pool heater. The AUX1 output energizes 10 seconds after the first unit compressor and de-energizes when the first unit compressor de-energizes.

AUX2 output is always off in this configuration.

3. EXT HEAT – When EXT HEAT is selected, AUX1 output is energized whenever there is a 1 st stage heat demand. This allows the use of a solar system in conjunction with this unit and the control will operate the solar system first and only bring this unit on if the heating demand is NOT being met by the solar system. AUX2 is always off in this configuration.

The 2 nd stage (HPPH) demand is initiated when water temperature has remained more than 0.5F

colder than the heat setpoint for more than 2 hours, or when the water temperature is 1.5F or more colder than the heating setpoint.

Remote Pool Operation

The control displays “Remote Pool” on the first line of the display while the 2 nd line displays “Cool”, “Heat” or

“Auto”. Pressing the UP or DOWN buttons toggles between these values. Factory default is “Cool”. The control uses the value selected when the MENU button is pressed to advance to the next item.

Pool Auto Mode

The control is equipped with a mode which will automatically heat and cool the pool within the range of the heating setpoint plus the Cooling Deadband (2-10F adjustable – default 6F) established in the

Installer/Service Sub-menu.

Fault History

The control is equipped to maintain fault history in the

Installer/Service menu. It will retain the last 10 faults

(starting with the most recent). If the fault history exceeds 10 events, the earliest fault drops off when a new fault occurs. NOTE: There is no time/date stamp associated with each fault. This history is intended to simply show what faults the unit has experienced.

When the “Faults Last” shows on the display, pressing the UP button toggles to the most previous fault.

Pressing the UP button toggles through the recorded faults. The faults are labeled on the first line of the display as Faults Last, Faults 2, Faults 3, etc.

Consecutive identical faults are only stored once.

Run Hours/Cycles

The control is equipped to monitor the number of run hours of the unit and the cycles of operation. This is accessible through the Installer/Service menu. These values are not resettable. The “Run Hours” tracks the number of hours that the compressor has been energized. This data is stored in non-volatile memory each time the demand for heat is satisfied. Hours and minutes are stored, although only hours are displayed.

The “Cycles” tracks the number of times that the compressor has been energized.

19

Compressor Start Delay

The control is equipped with a compressor start delay to prevent short-cycling of the compressor. The control will not energize a compressor unless the compressor has been off for at least 3 minutes. When this situation arises, the display shall read “Comp Start

Delay” until the timer clears and the compressor starts.

Minimum Run Time

To ensure proper operation of the compressor and longest life, the control has a minimum run time for the compressor of 3 minutes. If the setpoint is reached within 3 minutes, the compressor will continue to run for 3 minutes unless (1) the high pressure switch trips,

(2) the water pressure switch trips, (3) the high temperature limit is reached, or (4) the user selects “OFF” mode.

Defrost Operation

The control is equipped with several defrost algorithms depending on the configuration of the unit (HEAT

ONLY, POWER DEFROST or HEAT/COOL).

On this HEAT/COOL model, the control initiates a defrost cycle based on a programmed algorithm involving current and baseline ambient temperatures, and current and baseline coil temperatures when the coil temperature drops below the “Defrost Temp” set in the Installer/Service sub-menu. Factory default is 24F.

The control shuts off the fan and activates the reversing valve so the hot refrigerant gas is directed to the coil to defrost the coil. When the coil sensor sees temperatures above the “Def Terminate” value set in the

Installer/Service sub-menu, the unit returns to normal operation.

3-Way Valve Control

The control is equipped to control system 3-way valves. The control will set the 3-way valves to the state requested when there is an active thermostat demand for spa heat, pool heat or pool cool. This takes priority over positions requested by Pump

Schedule operations. If the control also controls the pump, the pump will shut off for 30 seconds before the valves change state so as to not have to fight pump head pressure during change of position. During this change, the display will show “Valve Chng Delay”.

The 3-way valves are field installed to the #38-40 &

#41-43 terminals on the terminal strip inside the junction box of the unit. The initialization of the 3-way valves is set in the Installer/Service sub-menu.

If the water pressure switch (or water flow switch) is closed when the control needs to change the 3-way valve position, the control displays “WPS Closed” and waits indefinitely with the pump and compressor off until the water pressure switch (water flow switch) opens. After it senses the open switch, the control switches the 3-way valves and resumes normal operation.

If no thermostatic demand is requesting operation and the pump is being run from scheduled pump periods, the control sets the 3-way valves to the states requested in the pump period mode schedule.

When there is no demand for pump output because of manually selected OFF mode, no thermostat demand or no scheduled pump period, the control leaves the 3way valves in their last commanded state. Valve outputs will not change until there is an active request for them to be in a different state.

The rating of the control contacts is 0.75A at 24VAC maximum.

Battery Back-up

The control is equipped with a battery to maintain control settings through power outages. This is located on the upper right rear corner of the control. Replace as necessary with a BR2032, 3V battery.

High Water Temperature Limit

The control is equipped with a high water temperature limit which will shut off operation of the compressor if either temperature sensor reads at or above 108F

(41C). The display will read “Hi Water Temp”. The compressor will remain locked out until both sensors are below 103F (40C) and the user presses the UP button. The high temperature limit is active in all modes of operation.

High Pressure Switch Lockout

If the high pressure switch opens, the control de-energizes the compressor output and the fan continues to run for 15 minutes after the HPS opened and the display will show “Hi Press Trip”. If the high pressure switch trips 7 times in a single cycle, the display will show “Hi Press Lockout” and the unit will be locked out of operation for 4 hours. The unit will automatically reset after 4 hours or the lockout can be manually reset by pressing the MENU button or cycling the power. The high pressure switch must close for 3 seconds for the control to recognize it as closed.

Low Pressure Switch Lockout

The control ignores an open low pressure switch for the first 30 seconds after the compressor is energized.

If the low pressure switch opens for 3+ seconds any time after this 30 second period, the compressor will shut down and “Lo Press Trip” will show on the display.

20

If the low pressure switch trips 6 times in a single cycle, the display will show “Lo Press Lockout” and the unit will be locked out of operation for 4 hours. The unit will automatically reset after 4 hours or the lockout can be manually reset by cycling the power. The low pressure switch must close for 3 seconds for the control to recognize it as closed.

Water Flow Switch

The control monitors the water flow switch. If the pump has run for 3+ seconds, there is a demand for compressor and the water flow switch is open, the control will prevent the compressor from running and show “Water PS Open” on the display. The water flow switch is checked to ensure that it is open BEFORE allowing the 3-way valves to switch. This ensures that the pump is OFF before trying to change the 3-way valve positions.

Sequence of Operation

1. Upon initial application of power, the HPPH control briefly sets all segments on the LCD at power-up.

2. The control displays the current software revision and the model type configuration (HEAT/COOL for these models) on the LCD for 2 seconds and then resumes the user selected mode it was in before power was interrupted.

3. Setpoints are read from non-volatile memory. If the checksum of the setpoints indicates corrupted values, “EEPROM Fault” is displayed on the LCD and operation is inhibited until setpoints are manually set.

4. If unit type has not been set (like during the replacement of the HPPH control), the control prompts the user to set the model type before any device operation is enabled.

5. Upon initial installation, there are several items that must be defined and programmed depending on the configuration and accessories intended to be controlled by the HPPH control. These include:

(1) 3-way valve control (Yes or No), (2) Pump control (Yes or No and then what type of control –

4-speed control or variable speed control), (3)

Auxiliary control (Yes or No and then what type –

External Heat, Auxiliary Output or Remote Output).

6. Once these choices are made, then additional information relating to the establishing of pump periods, pumps speed during each period and

Return/Suction Valve positions during each period must be determined and set in the control.

7. The options for the control can be very simple or quite complicated, depending upon each installation desires.

8. Once programming is completed, the control is ready for operation.

9. The user may select “On” for several operating modes depending on the unit type. Each mode is selected by pressing the MENU button to cycle between the modes. Each press of the MENU button selects the next mode. There is no automatic increment from continually pressing the MENU button. In fact, continually pressing the MENU button (for 3+ seconds) will move the user into the

USER Menu.

10. For HEAT/COOL models, the mode selections are

OFF – POOL COOL – POOL HEAT – POOL AUTO

– SPA – TIMED SPA.

11. REMOTE Mode is accessed by pressing and holding the UP and DOWN buttons simultaneously for

3 seconds. When exiting the REMOTE mode, the control always selects the OFF Mode.

12. If the UP, DOWN or MENU buttons are pressed while in REMOTE mode, the display will read “Exit

Remote Mode to Adjust Temp”. Mode and temperature setpoints are not changed.

13. Press and hold the UP and DOWN buttons for 3 seconds to exit REMOTE Mode.

14. When operating, the unit will continue to operate until the water temperature is 0.5F above/below setpoint (below for cooling), until a defrost condition is needed or the unit is manually turned off.

15. The unit will remain in standby waiting for the next heat/cool demand.

Controls

Your heat pump pool heater incorporates digital safety controls and indicators to ensure its safe, reliable operation.

Water Flow Switch: Prevents operation when the pump is OFF. The unit requires 20 gpm minimum water flow for unit operation.

Digital Water Temperature Control: The pool water temperature is controlled by the heat pump pool heater’s digital control system, which gives you the option of two settings: one for the desired spa temperature and the other for the desired pool temperature. Additionally, as mentioned earlier, the unit is compatible with most ‘2-wire’ and ‘3-wire’ control/automation systems.

Digital Controls Operating

Instructions

The electronic board has the capability of memorizing two different programmed temperature settings as follows:

• For a pool, maximum 95°F (35°C)

• For a spa, maximum 104°F (40°C)

21

To Increase or Decrease the

Desired Water Temperature

(Pool or Spa Mode)

With the MENU in either Pool or Spa mode, simply press the UP or DOWN buttons to raise or lower the setpoint. Holding the UP or DOWN button will increment the setpoint 1 degree at a time, but continuing to hold either button will result in a “Speed-Up” mode which will increase the speed of number changes.

Select Temperature in °C or °F

Press the MENU button for 3+ seconds to enter the user mode. Once in the user mode, toggle to the 2nd entry and using either the UP or DOWN buttons, change the temperature readings into °C or °F.

When complete you can press and hold the MENU button for 3+ seconds to return to the operating mode or simply wait and the program will automatically return to the operating mode in 180 seconds.

Heat/Cool Operation

These units are equipped to provide both heating and cooling to the pool.

NOTE: Remove the pool/spa blanket and turn on any fountains, sprays or other water features to speed cooling.

When the unit has been operating in the heating mode for a few minutes, the discharge air temperature should be 8°–10°F cooler than the air entering the unit.

When the unit has been operating in the cooling mode for a few minutes, the discharge air temperature should be 8°–10°F warmer than the air entering the unit.

NOTE: Heating is more efficient during warmer daylight hours and cooling is more efficient during cooler night time hours.

System Start-Up

1. Verify that the Digital Board is displaying a temperature and the pool pump is running and water is circulating properly.

2. Verify that the Board is programmed so that the desired temperature of the Pool and/or Spa is higher than the displayed current water temperature.

3. Allow the heat pump pool heater to operate for a few minutes to stabilize operating pressures and to allow various component temperatures to normalize.

4. Verify that the discharge air temperature is approximately 8°–10°F cooler than the air entering the unit (in heating mode). If not, see the

Troubleshooting Section.

Seasonal Start-Up or Annual

Check

NOTE: At the beginning of the heating season or whenever the pool water temperature is to be raised several degrees, the pool pump and heat pump pool heater may need to operate continuously for several days. During summer months, only a few hours per day may be necessary or none at all.

1. Remove leaves, pine needles, etc., from the evaporator coil. Clean the coil by gently applying a mild solution of household liquid soap and water.

2. Gently rinse the coil with water; DO NOT use high pressure.

3. Backwash or otherwise clean the pool filter. If necessary, clean the skimmer basket and pump strainer.

4. Set the valves to ensure proper water flow through the unit.

NOTE: If the pool pump and heat pump pool heater shut OFF before the water temperature is raised to the desired level, you must lengthen the running time of both. To do this, reset the time clock dial for the longer running time, or manually operate the pump with the timer override switch. Since the heat pump pool heater capacity and efficiency are both greater at higher ambient air temperatures, run time should be set to take advantage of all daylight hours, when the air is generally warmer.

Summer Shutdown

If you do not plan to use the heat pump pool heater during the summer months, secure and protect it as follows:

1. Turn the unit circuit breaker or disconnect switch to

OFF.

2. Leave the valves set the way they are unless additional circulation is required. DO NOT stop all flow through the heat pump pool heater.

22

3. IMPORTANT: Remember to reset the valves before the next heating season, or the unit will not operate properly.

Freeze Protection

If the unit is installed in a location subject to freezing conditions, it is important to protect the water circuit from freezing, just as should be done for the pump and filter.

System Drain-Down

1. Turn the unit circuit breaker or disconnect switch to

OFF.

2. With the pool pump OFF, close the external shutoff valves and remove the drain plugs located in the inlet and outlet water unions to allow water to drain.

Maintenance

The following maintenance procedures are designed to keep your unit operating at a high level of reliability.

Maintenance must be performed on a periodic basis to maintain warranty coverage and prevent system failures and performance degradation.

Air Coil Cleaning

Efficient operation depends on free circulation of air through the thin and tightly-spaced fins of the evaporator coil(s). The evaporator must be cleaned whenever it has a buildup of dirt or debris.

CAUTION: To clean the fins, spray gently with a garden hose. DO NOT pressure wash. Doing so will bend the fins and can void the warranty.

Cabinet Care (optional)

WARNING: Shut OFF electricity to the unit before cleaning.

The stainless steel cabinet is designed for outdoor use and requires little care. However, you can clean it if you wish. Wash the cabinet with soap and water.

Unplug Condensation Drain

Holes

The unit extracts humidity from the air as it passes through the coil, similar to the way a cold drink outside

“sweats” on a hot day. This condensation drains from the bottom of the unit.

1. Routinely check to be sure the condensation drain holes in the base of the unit are not plugged with dirt or debris.

Fig. 5: Drain Plugs Locations

3. Use a wet/dry vac or air pressure to remove excess water- as necessary.

4. Once the water is drained, reinstall the drain plugs.

5. Cover the unit with a waterproof cover.

Continuous Pump Operation

It is also possible in some areas to prevent unit freeze damage by operating the pump continuously during freezing weather. However, this results in significantly higher pump operating costs. Further, if a sustained power failure occurs, the unit MUST be drained anyway, or freeze damage could result.

NOTE: The heat pump pool heater MANUFACTUR-

ER IS NOT RESPONSIBLE for maintenance adjustments.

Fig. 6 : Condensate Drain Hole Locations

23

2. If condensation becomes a problem, optional drain pans may be available from your heat pump pool heater distributor or pool dealer.

Troubleshooting

If your unit does not operate, or simply does not heat your pool water, Fault Messages on the front control panel can provide valuable clues as to what is wrong, and may even indicate precisely what the problem is.

Always observe these messages before calling a service representative. By reporting on the telephone the

Fault Messages that are showing, the service rep may be able to solve the problem without the expense of a service call.

A. UNIT IS RUNNING, BUT NOT HEATING

• Is water flow through the unit adequate? Check the unit for obstructions, such as a clogged filter pump strainer, a dirty filter, or valves not positioned correctly.

• Is the ejected air from the unit 8°–10°F cooler than incoming air? If so, the unit is extracting heat from the air and transferring it to the pool.

• Is water condensing on the evaporator and internal copper pipes? This is also evidence of heat removal from the air. When the air is cool with low humidity, condensation may not be evident.

• How long has the unit been operating? During initial pool heating in cold weather, it may require a week to elevate the water temperature to a comfortable level. Normally, it takes about 4 days.

How many hours per day is the unit operating?

Remember that the heat pump pool heater only operates while the pool pump is running.

Set the time clock to permit 24 hour per day operation. After the desired temperature is reached, return the unit to normal operation of 8–10 hours per day.

NOTE: If the pool pump and heat pump pool heater shut OFF before the water temperature is raised to the desired level, you must lengthen the running time of both. To do this, reset the time clock dial for the longer running time, or manually operate the pump with the timer override switch. Since the unit capacity and efficiency are both greater at higher ambient air temperatures, run time should be set to take advantage of all daylight hours, when the air is generally warmer.

• Is airflow through the unit being obstructed?

Restrictions such as shrubbery, tall grass, dirty coils, or any other obstruction to airflow will reduce performance.

• Is the pool blanket/cover being used?

Unblanketed pools can lose up to 10 degrees per night compared to 4 degrees or fewer when a blanket is used. Without a blanket, the total heat gained during the day can be lost overnight.

• Are rapid heat losses occurring in some other way, such as high wind, spillage, rainfall, flow through solar panels at night, or a high water table?

B. UNIT IS NOT RUNNING

• Is the temperature display ON? If not, the circuit breaker may be shut OFF or tripped. Reset the breaker by switching it OFF, and then back ON.

Verify that the breaker is set and operating properly before calling for service.

• Are the Pool/Spa settings correct? Verify that the temperature has been properly set on the thermostat, and that it is higher than the current water temperature.

• Have you waited approximately 5 minutes for the time delay? After the unit has been running and then shut OFF for any reason, there is a delay before operation can begin again. The display will read “Comp Start Delay” when this 5 minute delay is active.

NOTE: The heat pump pool heater will not run when the Remote position is selected on the Pool/Spa control and there is no remote control system attached.

C. CONDENSATION SEEMS EXCESSIVE

Heat pump pool heaters can produce a large amount of condensation (water) during operation. If you suspect that the unit is leaking:

• Shut the unit OFF and leave the filter pump running to see if the water stops dripping. If the water stops dripping, the unit is not leaking.

24

Troubleshooting

Before troubleshooting the system, ensure that:

• All mechanical and electrical connections are secure and tight

• All system wiring is correct

• Fuse is not blown (3A Automotive “ATO” type fuse for 24VAC)

• That a system ground is properly connected to the heater. Nuisance shutdowns are often caused by a poor or erratic ground.

The service display can be accessed by pressing and holding the UP and MENU buttons for 3+ seconds. The service display does not affect operation of the unit which continues to operate in the background. When in this mode, pressing the UP or DOWN buttons will toggle through the various information reported. Some items (Fault

History and Sensor Temperatures) have multiple values (press UP or DOWN buttons to scroll through the additional information). The service display mode may be exited to return to the previous display be pressing the UP and MENU buttons or it will automatically be exited if no button is pressed within 60 seconds.

Service Call Verification

NOTE: The Raypak Service number is 800-260-

2758.

Before you make a service call, first determine if the problem is:

• Warranty Service - must have model number, serial number and date of installation.

• Unit operation (power supply, water flow, or time clock adjustment)

NOTE: The MANUFACTURER IS NOT RESPON-

SIBLE for these adjustments.

Power Supply

• Verify that all circuit breakers are reset and working properly.

• If the temperature display on the control panel still does not light, contact the installing dealer, since it may be a power problem requiring an electrician.

Water Flow

• Verify that the pool filter is clean to provide good flow.

• Verify that valves are properly positioned to allow adequate water flow through the unit.

Time Clock Adjustment

Verify that the time clock is set to permit the unit to run long enough to heat properly.

Set Factory Defaults

If programming is messed up and no operation can reliably be made, the control board can be reset to

Factory Default values as noted in Table D. This operation changes all adjustable settings to factory default settings.

Enter the Installer/Service Mode by holding the MODE and UP buttons for 3+ seconds. Scroll through the information until you reach the "Installer Menu" screen

- press the UP or DOWN button until YES appears on the 2nd line. Press the MODE button to access the additional Service information. Continue to press the

MODE button until "Set Factory Defaults" appears on the display. Press and hold the UP and DOWN button for 5 seconds to reset the control to factory defaults.

The display will read "Defaults Set" when completed.

NOTE: Previous settings will be erased and are no longer recoverable. All settings will have to reentered by hand to re-establish proper operation.

100K sensors are used for water temperature measurement. These sensors are dual thermistors in a single sensor housing. The control uses both sensor reading in operating the unit. If the control measures temperatures on these thermistors which are approx. 10F apart, the control will shut off the compressor and show “H2O

Sensor Fail”. The message will be cleared and operation resume when thermistors are within 7.5F of each other.

The sensor has a measurement error of less than +/- 0.5F between 36F and 110F temperatures. The control displays 100K sensor temperatures to 0.1F or 0.1C resolution. The water temperature used for thermostat decisions is the average of the 2 thermistors.

10K sensors are used for the Outdoor Air Temperature sensor, the Coil Temperature sensor and Aux Heat

Temperature sensor (field supplied when necessary). The sensor has a measurement error of less than +/- 0.5F

between 36F and 110F temperatures. The control displays 10K sensor temperatures to 0.1F or 0.1C resolution.
