III.OWNER’S INSTRUCTIONS FOR HP7 DIGITAL HEAT PUMP CONTROLLER

WELCOME TO THE AQUACAL FAMILY

Congratulations on your wise decision to make an AquaCal heat pump part of your home. Since 1981, AquaCal has maintained the worldwide lead in the manufacture of swimming pool & spa heat pumps.

Your new heat pump is not only a great investment, but also the most cost effective method available for heating pools and spas. For example, as a means to heat pool or spa water, your heat pump is up to 400% more efficient than gas, and, when compared to electric resistance heat, your heat pump is nearly 600% more effective. You can rest assured that your new heat pump is of the highest quality and efficiency, and is designed and built to provide years of trouble-free operation.

Moreover, should you decide you would like AquaCal to provide regular inspection and maintenance for your heat pump–which we do recommend–you will find that AquaCal has the largest and most-qualified factory-trained service staff in the pool & spa heat pump industry.

IMPORTANT FEATURES OF YOUR NEW HEAT PUMP

YOUR NEW HEAT PUMP IS EQUIPPED WITH THE FOLLOWING INNOVATIVE FEATURES:

∙ThermoLink™ Heat Exchanger:

The heart of your heat pump is the patented ThermoLink™ heat exchanger. The primary cause of premature heat pump demise is the failure of the heat exchanger. Ordinary heat exchangers are made from a cupronickel alloy. This cupronickel material is susceptible to attack from the sanitizers used in pools and spas, and from other related water chemistry conditions. Once the heat exchanger fails, the heat pump is ruined. The ThermoLink™ heat exchanger tube is made from titanium, and is virtually impervious to water-chemistry damage.

∙Scroll Compressor:

Scroll compressors contain 50% fewer moving parts than common piston-type compressors. Less moving parts equates to much improved reliability. Additionally, scroll compressors are much quieter in operation than piston-type compressors, and operate at a considerably higher efficiency level.

∙Microprocessor Control:

Full-feature, digital-based microprocessor, controls water temperature to within 1º Fahrenheit of set point. The controller also permits user to predefine different pool and spa water temperatures, and to prevent tampering by locking out controls using a pass code.

∙Corrosion-Proof, UV-Protected Cabinet

∙Quiet Operation… Through the use of a scroll compressor and optimally-sized fan blade.

PLEASE SPEND A FEW MINUTES READING FURTHER TO BECOME FAMILIAR WITH ALL THE FEATURES, THE SAFE OPERATION, AND THE CARE OF YOUR NEW HEAT PUMP…

GENERAL SAFETY INFORMATION

Used and maintained properly, your heat pump will provide year-upon-year of safe and economical service. However, as with any mechanical or electrical device, to get the most from your heat pump–while insuring personal safety for you and others–certain operational and maintenance factors must be observed.

Likewise, excepting a few minor owner-capable maintenance items (explained later in this manual), repair and service of your heat pump must be performed only by experienced service personnel. Should you, the owner, suspect your heat pump is not performing properly, by referring to the section in this manual entitled: “Troubleshooting”, you will be able to determine if a call for service is required. Your installer can be one source of service, or AquaCal Customer Support personnel stand ready to assist you at: (800) 786-7751. For questions concerning installation, modifications, operation, service and upkeep, please contact your installer or AquaCal Customer Support. Warranties may be voided if the heater has been used, maintained, or repaired improperly.

In addition to possible voiding of warranties: unapproved installation methods, non-standard modifications, poor or incorrect maintenance, service by unqualified personnel, or improper use of the heater may result in personal injury and/or property damage. For personal safety and to avoid damage to equipment, it is important that safety instructions displayed on the heat pump, and within this manual, be read, understood, and followed.

Throughout this manual the following two safety signals are placed where particular care is required. Please note: “WARNING” relates to personal safety, while “CAUTION” signals promote avoiding damage to equipment:

WARNING !	Failure to heed the following may result in
WARNING !	permanent injury or death.

This “Warning” symbol appears in this manual where special attention is required for personal safety. Specific instructions will appear in this box.

WATER CHEMISTRY & TEMPERATURE FACTORS

Water Temperature Safety Factors

WARNING !	Failure to heed the following may result in
WARNING !	permanent injury or death.

Prolonged immersion in water warmer than normal body temperature may cause a condition known as HYPERTHERMIA. The symptoms of hyperthermia include: unawareness of impending hazard, failure to perceive heat, failure to recognize the need to exit spa, and unconsciousness. The use of alcohol, drugs, or medication can greatly increase the risk of fatal hyperthermia. In addition, persons having an adverse medical history, or pregnant women, should consult a physician before using a hot tub or spa. Children and the extreme elderly should be supervised by a responsible adult.

Water Chemistry Safety Factors

WARNING !	Failure to heed the following may result in
WARNING !	permanent injury or death.

Improper water chemistry can present a serious health hazard. To avoid possible hazards, maintain Pool-Spa water per standards below.

CAUTION !	Failure to heed the following can result in
CAUTION !	damage to equipment.

While your heat pump’s titanium-based heat exchanger provides nearly impervious protection against poor water chemistry, improper water chemistry may cause expensive damage to pumps, filters, pool shell, etc. To avoid equipment damage, maintain Pool-Spa water per standards below.

RECOMMENDED CHEMISTRY WATER STANDARDS

Chlorine………………:	1.0	– 3.0 ppm in pools, 1.5 – 3.0 ppm in spas
Bromine………………:	2.0	– 4.0 ppm in pools, 3.0 – 5.0 ppm in spas
PH…………………….:	7.4	– 7.6 in pools, 7.2 – 7.8 in spas
Total Alkalinity………:	80 – 140 ppm in pools, 80 – 120 ppm in spas
Calcium Hardness……:	200 – 400 ppm in pools and spas
Total Dissolved Solids..:	1,000 – 2,000 ppm in pools,
	1,500 ppm above your start-up TDS in spas

HOW A HEAT PUMP WORKS

THE FOLLOWING EXPLANATION IS PROVIDED TO HELP YOU IN UNDERSTANDING WHAT TO EXPECT FROM YOUR HEAT PUMP…

A Heat Pump Does Not Make Heat…

Heat pumps are so extraordinarily efficient because they do not need to produce heat in order to warm pool or spa water. Rather, heat pumps simply transfer heat from the outside air into the pool or spa water. If one considers that absolute “0”–the point where all heat is absent–occurs at 459º Fahrenheit below zero, it becomes evident that outside air–even at the relative cool temperature of

55ºFahrenheit–still contains large amounts of heat energy. It is that abundant heat energy that a heat pump captures and places into your pool or spa.

FOR A MORE DETAILED EXPLANATION OF DIGITAL CONTROLLER OPERATION, AND ASSOCIATED DISPLAY CODES, SEE OWNER’S INSTRUCTIONS FOR HP7 DIGITAL HEAT PUMP CONTROLLER LOCATED IN THE APPENDIX OF THIS MANUAL.

GETTING YOUR HEAT PUMP STARTED & STOPPED

ATTENTION:

THIS IS A QUICK-START GUIDE…For more complete information concerning the digital controller features and programming, see: Owner’s Instructions for HP7 Digital Heat Pump Controller, located in the appendix of this manual.

INITIAL START UP

1. Start the water circulator pump.

NOTE: THE POOL FILTER PUMP MUST BE OPERATING FOR THE HEAT PUMP TO BEGIN HEATING. ANYTIME THE POOL FILTER PUMP IS TURNED OFF, THE HEAT PUMP WILL ALSO BE OFF.

2.Ensure that the unit has power connected; display should be illuminated.

3.If the display is blank, be certain the breaker and heater disconnect are switched to “ON”.

HOW TO OPERATE THE CONTROLS

1.Once the unit has power connected, the display should read either “OFF” or the actual pool or spa water temperature. If other than “OFF” or the actual water temperature are displayed, see the “Trouble Shooting” section.

2.If the display reads “OFF”, press the up arrow key until the display reads 60°F or higher.

NOTE: THE DISPLAY READS CURRENT POOL / SPA WATER TEMPERATURE WHEN THE

DESIRED TEMPERATURE IS SET TO 60°F OR ABOVE. WHEN THE DESIRED WATER TEMPERATURE IS SET BELOW 60°F THE DISPLAY READS “OFF”.

3.Once the unit is displaying the current water temperature, the system is ready to operate. Locate the POOL / SPA selector key on the control panel; by pressing this key, you can select between the pool and spa mode.

4.Using the POOL / SPA selector key, select the pool mode. When the pool mode has been selected, the pool indicator light, located on the left side of the display, will be illuminated.

5.With the control in the pool mode, use the UP / DOWN arrow keys to set the desired pool water temperature.

6.If heater is also being used to heat a spa, repeat the previous two steps to program the desired spa water temperature.

7.The heat pump will now maintain the desired water temperature for the mode selected: POOL, or SPA.

GETTING YOUR HEAT PUMP STARTED & STOPPED

(Continued)

8.In operation, whenever the actual (displayed) water temperature falls below the desired set point, the unit will start heating after an initial time delay of 3-4 minutes.

NOTE: THE HEAT PUMP INCORPORATES AN ANTI-SHORT CYCLE TIME DELAY. SHOULD OPERATION BE INTERRUPTED, RESTART WILL BE DELAYED BY APPROXIMATELY 4-MINUTES.

CONTINUOUS USAGE AND WATER AROUND UNIT

oIf you have followed the directions up to this point, you should be on your way to enjoying a warm pool or hot spa.

oAfter the heat pump has been running for some time, you may see water present around the heater. This water is condensation produced as a by-product of transferring heat from the air to your pool or spa. If the humidity is high, water quantities of 6-8 gallons per hour are not uncommon. Conversely, a lowhumidity condition may result in no condensation being produced.

REQUIRED HOURS OF POOL PUMP OPERATION

SOME POOL SYSTEMS UTILIZE A TIMER TO CONTROL THE POOL FILTER PUMP ON A TIME-OF-DAY BASIS. IF YOUR POOL SYSTEM INCORPORATES A TIMER, USE THE FOLLOWING INSTRUCTIONS:

oIt will be necessary to allow your pool circulator pump to run continuously until the pool has reached the desired temperature.

oIf a timer controls your pump, it will be necessary to override the timer to temporarily allow for 24-hr. pump operation.

oOnce the desired temperature has been obtained (this may take up to four days), you should reset your pump time clock for normal operating hours.

REMEMBER … THE HEAT PUMP CAN ONLY OPERATE WHEN THE CIRCULATOR

PUMP IS RUNNING. THEREFORE, IN ORDER TO KEEP UP WITH INCREASED HEAT LOSS DURING COOLER WEATHER, IT MAY BE NECESSARY TO EXTEND THE PUMP’S DAILY HOURS OF OPERATION.

TO SHUT THE UNIT OFF

oThe unit can be stopped by switching off the electrical supply or by setting the desired temperature lower than the actual water temperature.

o The unit will display “OFF” if the desired water temperature is set below 60°F.
