INTRODUCTION

A Cost-efficient Heater

Y our new pool heat pump will help you save money compared to other types of pool heat-

ers.

In fact, even if your pool heat pump has a lower heat capacity which makes it run for 24 hours a day , the pool heat pump remains the most economic system, because of the use of state of the art technics in thermodynamics.

How Does It Work?

Y our pool heat pump works just as a water pump does. Whereas a water pump is tranferring water from one place to another , your pool heat pump is transferring heat between the surrounding air and your pool water. Moreover , your pool heat pump is not producing heat with the energy it is consuming just as a water pump is not producing water. It is because of this principle that your pool heat pump may attain efficiency ratios going up to 600% or 700% in the best climatic conditions. This means that for each kilowatt your pool heater consumes, it is transfering 6 or 7 kilowatts from the surrounding air to the pool water . The difference is astronomical compared to oil, gas or electric resistance heaters yielding only 80 to 95% output. But it is true to say that the output of traditional pool heaters stays constant at any outdoor climatic conditions whereas the output of a pool heat pump varies. However , even when temperatures are cooler the pool heat pump continues to transfer heat between air and water and it stays the best choice for temperatures down to 5 Celcius (41 Fahrenheit) overnight.

Y our pool heat pump is designed for lower maintenance at a lower cost. But if you want your pool to be heated efficiently , you must follow the advice supplied in this manual.

Low Maintenance

SELECTING THE LOCATION

The area you choose for your pool heat pump is very important. Y ou must consider the

following.

Air Supply and Accessibility

Y our heat pump uses the surrounding air to work. It is very important that you make sure there is enough air circulation around the heat pump. Do not install the heat pump in a closed space like a garden shed, a garage, or a basement.

The table below indicates the minimum distance from the heat pump that any object should be located.

Generation (CP) Eclipse (MP)

(1) facing the coil surfac es (2) facing other surfaces (3) facing fan * (4) facing servi ce panel

* Objects should be placed as far as possible from where the air is discharged.

2 feet = 61 cm 10 inch = 25.4 cm 4 feet = 122 cm 2 feet = 61 cm or accessible

2 feet = 61 cm 14 inch = 35.5 cm 4 feet = 122 cm 2 feet = 61 cm or accessible

CP Model MP Model

Other Recommendations

Do not install the heat pump under a roof. Doing this will protect the heat pump from being buried by snow or receiving heavy rainfall from the roof that does not have gutters.

Also, make sure that the digital control does not face the sun. The control will not break but its digital display will be more difficult to read.

If you have an automated sprinkler system for your lawn, make sure that the heat pump is not showered by a sprinkler.

The pool heat pump should be installed on a firm and leveled surface, preferably on a concrete slab or something equivalent.

Keep in mind that the heat pump will cause condensation. Therefore water will be dripping from the heat pump.

WATER INLET AND OUTLET CONNECTIONS

) )

For your own security , and to ensure proper operation of the unit, the water connection must be performed by a qualified person as per all applicable national, provincial, state or local codes.

For all Eclipse (MP) models, connection pipes are 1 1/2 inches in diameter . For all Generation (CP) models, the connection pipes are 2 inches in diameter. For all the pool heaters, we recommend (obligatory for the Eclipse series) the installation of a set of valves allowing to isolate the pool heater from the filtration system when necessary . (See the drawing below.) Moreover , you have to make sure that your pool heat pump may be disconnected from the pool pipes without having to stop the water pump or without losing great quantities of water .

All CP’s : Closed - the internal calibrated valve regulates the water flow , exception for those who have a water pump of 2hp or greater , adjust the valve to obtain the flows listed below.

If the previous settings are not respected, the pump or the pool heater may be over-

charged and result in failure of your equipement.

Y our water pump must provide the quantity of water indicated in the table below . These numbers must be used for each pool heat pump installed. A flow meter must be installed on the water inlet of the pool heater to know the exact water flow . Caution : many flow meters require a long distance of straight tubing on the inlet side to offer an adequate measurement.

Chlorinators, Brominators and Other Automatic Systems

Any automatic distribution system of chemical products, chlorine, bromine or others, must be installed after the outlet of water from the heat pump. The warranty of the

heat pump will be voided for any installation that is not in accordance with this rule.

The use of a brominator or a chlorinator tends to lower pH and total alkalinity because of the chemicals in it. If you use such a product, you must check the quality of the water regularly. (Addition of sodium bicarbonate is recommended to restore the balance.) (See the section Water Maintenance on p.12.)

Water pump

Filter

This connection method is strongly recommended

to enhance the life-span of your pool heat pump.

If you connect the unit this way , you have to pour chemicals directly into the pool or the spa, as far as possible from the water supply point.

Do not pour chemicals in the skimmer or at the

bottom of the pool, if you have a drain, because of

the possibility of migration of the chemicals to the

heater .

The p-trap should be installed higher than the top of the chlorinator (brominator) to prevent migration.

Salt Chlorinator

Salt chlorinators are made to be installed like in-line chlorinators. Therefore, they must

be installed in accordance with the “In-line Chlorinator or Brominator” connection directives, else the warranty of the heat pump will be voided. (See the section “Water Main-

tenance” on p.12 and the section «Salt Generated Chlorine» on p.15 for more information on operating salt chlorinators.)

Dual Unit Connection

For some larger pools, it may be necessary to install two units in parallel. In this case, double the distances recommanded in the table 1 of the page 5. Never place two MP models coil against coil, fan against fan or coil

against fan.

1,2 and 3 : calibrated valves 4 : filter 5 : water pump 6 : flow meters

When the access to a heat pump is shut off, the water flow passing through this heat pump will be redistributed among all others. Therefore, the valves mus be re-adjusted to meet the water flow requirements.

POOL AND SP A CONNECTION

Using One Pump and One Filter for the Pool and the Spa

An installation featuring a single pump and a single filter for the pool and the spa is easier and more economical. Using home automation, it is possible to always keep the pool and the spa to the desired temperature. Otherwise, it is always possible to have only the desired system functioning by positioning the valves to have the water circulating in the pool or in the spa.

1) It is more difficult to maintain ideal levels of chemicals in the water when using a single filter because this type of installation prevents the pool or the spa from being filtered. An independent home automation system with automatic valves can reduce this problem, or you must be very assiduous in maintenance.

2) For the pool heat pump to automatically detect the switch over from pool to spa and vice versa, a flow switch must be added on the spa line.

Using Independent Pumps and Filters for the Pool and the Spa

An installation featuring independant pumps and filters for the pool and the spa is a little more complicated and expensive. However, it is more advant ageous because the pool or the spa is never left without filtration. W ater is therefore easier to maintain.

1) For the pool heat pump to detect the change made either manually or by an independant system, a flow switch must be added on the spa line.

ELECTRICAL CONNECTION

For your own safety , and to ensure proper operation of the unit, the electrical connections must be performed by a qualified electrician as per all applicable national, provincial, state or local electrical codes.

A breaker must be installed near the heat pump in an accessible area.

Never open the electrical box without shutting off all power sources to the heat pump. If your heat pump features a water pump control option, do not forget to shut off the breaker to this water pump.

The identification plate on the heat pump identifies all voltage requirements.

If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a qualified electrician to avoid electrical shock.

Page 10

MAINTENANCE

Before performing any maintenance on the heat pump you must turn off the breaker of the electrical supply line.

Cleaning

T o ensure optimum performance of the heat pump, follow these recommendations:

- Backwash the filter of the pool on a regular basis in order to ensure proper flow rate

through the pool heater;

- Keep the surfaces of the coil clean and free of any obstruction such as papers, leaves or

other debris;

- Carefully clean the unit using a soft, non abrasive and bleach free cleaner , and rinse

using a garden hose without the nozzle;

- Check the drainage holes of the base of the unit to make sure that they are clean and

unobstructed. (This prevents water from accumulating in the heat pump.)

Winterizing (Cupro-nickel heat exchanger)

If you close the swimming pool during the winter season, it is essential to drain the unit in order to prevent the formation of ice in the condenser (water section). To winterize the heat pump, you must :

1. Stop the unit;

2. Shut off the breaker of the heat pump electrical supply line;

3. Disconnect the water intlet and outlet connections (See “Water Deviation” for details.);

4. Freely flush the condenser with tap water . Completely drain the system using air pres-

sure or vaccum system. We do not recommand putting anti-freeze into the heat pump

pipes, but if you chose to put some, make sure it is compatible with copper , otherwise, it

would do more damage to the condenser than small quantity of ice would;

5. If the heat pump is left outside during winter , protect it with a waterproof cover .

Winterizing (Titanium heat exchanger)

1. Stop the unit;

2. Shut off the breaker of the heat pump electrical supply line;

3. Loseen the bypass valves (photo A) and let the water drain out (See “Water Deriva

tion” for details.);

4. Unscrew the small cap (photo B) with the help of two wrenches (photo C) and freely

flush the condenser with tap water. Completely drain the system using air pressure or

vaccum system. Store the small cap during winter .

5. Block the opening of either the water inlet or outlet pipe (photo D) with your hand and

blow air into the pipe not covered by your hand to flush out the water completely . If the heat

pump is left outside during winter , cover it with a waterproof cover.

Seasonal Start-up

Before starting the pool heat pump for the first time of the season, you must :

1. Verify and adjust the quality of the pool water (see chapter "W ater Maintenance" to find

out about the amount of chemicals to be used in your swimming pool);

2. Make sure that the electrical breaker of the pool heat pump is in the off position;

3. Connect the heat pump to the water circuit;

4. Clean the pool filter and make sure that the water is flowing adequately through the pool

return line;

5. Switch on the breaker of the heat pump electrical supply line.

Water Deviation

Some maintenance operations(System Shock) require that the pool heat pump be isolated from the filtration system to keep the heat exchanger from suffering damage over time. By using the method of deviation, you will be able to block access of pool water from entering the pool heat pump. T o derive the water , you must :

1. Stop the unit.

2. Open the by-pass valve and close the water inlet and outlet valves (Photo 1.)

After a longer period of inactivity (1 week or more):

3. At the beginning of spring, when you prep are your swimming pool, make sure that the

water is stable by checking the pH, alcalinity and chlor level before starting your pool heat

pump. (T o find out about the amount of chemical products to use in your swimming pool,

consult the chapter on "Water Maintenance" in the manual.)

4. When the water is stable, you can close the by-pass valve and open the water inlet and

outlet valves (Photo 2) to end the deviation process.

WATER MAINTENANCE

Why Perform Water Maintenance?

Contrary to traditional heat pumps that treat air only , pool heat pumps deal with water and are much more sensitive. This is mainly caused by water chemistry . Only you, the owner of the heat pump, can control the chemistry of your swimming pool water to avoid premature degradation of your pool heat pump.

Water Chemistry

Many chemicals are used to control the quality of swimming pool water. W e use different types of chlorine or bromine to control microorganisms and algae. We also use various products to regulate pH and other aspects of the water chemistry. Every product added produces an effect on water chemistry that must often be balanced with other chemical products. For example, trichlor addition induces a diminution of pH and of total alkalinity (T A). We must balance those effects by adding sodium bicarbonate (baking soda).

Some organizations, like the NSPI (National Spa & Pool Institute), publish standards on pool water chemistry. Those standards are made to protect swimmers and swimming pool equipments, particularly their metal parts, copper , steel and even stainless steel, that will corrode under the effect of bad chemistry . Generally , if the equipment can be damaged by bad chemistry , this can also be a health hazard. (See the following table for the standards.)

Your heat pump, just as any type of pool heater (gas, oil, electric, etc.), features some metal parts that can be damaged by bad chemistry. The condenser of your pool heat pump is made of a copper alloy that, as resistant as it is, is sensitive to pH. That is why we strongly recommend testing the quality of the pool water regularly . These controls must be made on a weekly basis and must at least feature the following: chlorine or bromine, pH and T A. Moreover ,

Page 14

we suggest having the pool water tested by a professional (often free of charge) once a month.

The water of the pool or spa must be maintained within the standards included in this manual. Any negligence to do so, will void the warranty. These standards are from the NSPI and are common throughout the swimming pool industry; they are not particular to T urcotte heat pumps.

The most important factor for the durability of the pool heat pump is the pH because the capability of the water to cause the degradation of metal is directly related to it. Let’s also mention that T A is the measure of the capacity of water to resist to pH variation; therefore it is as important. T aylor , an important manufacturer of pool water test kit for professionals states:

“Corrosive water will dissolve copper piping and heat exchangers and leave stain on

pool walls.” [T aylor , A T esting & T reatment Guide part #2004B, p.35] “The result is a highly unbalanced water condition resulting in damage to copper heat

exchangers, light rings, stainless steel ladders an concrete pool surface.” (T alking about

acidity and low T A) [Taylor , A T esting & T reatment Guide part #2004B, p.1 1]

Sanitizers

Sanitizers are products used to purify water , to relieve it from microbes and algae. They are chlorine, in its different forms, and bromine in the case of the pools. Each of them has its advantages and inconveniences. They are sometimes basic, sometimes acid. They can have different impacts on water chemistry and can necessitate various chemical products to counterbalance those impacts or to stabilize them. W arm water is more difficult to maintain, it necessitates greater quantities of sanitizers and, therefore, greater quantities of other chemical products.

Never pour any sanitizer directly into the water intake (skimmer) without having deviated the water from the pool heat pump previously. (See the section "Water Deviation", p.11.)

NOTE: The use of a floatting distributor is recommended as an alternative to pourring chlorine directly into the skimmer. Maint aining the chlorine level using this method can however be more difficult because the water flow dissolving the chlorine is less important on the top of the pool than in the water pump system.

Shock Treatment

Before performing any shock treatment, deviate water from the pool heat pump to prevent chemical products from damaging it

1) Trichloro-s-triazinetrione (TCCA or trichlor or pucks)

Trichlor is a very common and practical sanitizer because it dissolves into hypochlorous acid, a powerful sanitizer, and into cyanuric acid, a st abilizer improving the duration of its efficiency . However , it produces 2 acids that contribute to lowering pH and AT of the pool water . This can cause severe damage to the pool and to its system because of corrosion:

“…having a strongly acidic pH, TCCA tablets will reduce total alkalinity and, if not moni- tored, low total alkalinity will cause corrosive damage to the pool.” [Taylor, A Testing & Treatment Guide part #2004B, p.26]

Usage of trichlor requires the addition of sodium bicarbonate to higher the pH and TA level. Warning: many users testing only pH will be tempted to use sodium carbonate, or pH+, however this product does not increase T A level and pH will decrease back rapidly . As acidic water is also most of the time very clear because it is free of microorganisms, T.T.I. wants to remind you to test water regularly to avoid problems caused by acid water . Clear water is not a synonym of good quality water.

NOTE: With trichlor, it is possible to use what is called a chlorinator . A chlorinator is an automatic chlorine distribution system, but in no case it is controlling pH and TA of

water. Thinking their system is completely automatic, users of those systems of ten neglect to test their water . Moreover, make sure that your heat pump installer has modified the circuit of your chlorinator in a manner to prevent it from pouring out its concentrated solution of chlorine into the pool heat pump. (See p.7)

Page 16

2) Bromine

Bromine is a very good sanitizer. It is safe and practical. It does not require any st abilizer and it does not cause irritation nor has any odor . Furthermore, its efficiency is independent from pH of water. However, it is acid and it destroys T A. W ater that is acid and low in TA becomes corrosive and disintegrates metallic pieces of the pool system, including the heat exchanger of your pool heat pump. Therefore, it is imperative to test water frequently, even if water is very clear, to avoid problems caused by water acidity . Acid water is often very clear because it is free of microorganisms, but it is damageable and of bad quality .

NOTE: with bromine, it is possible to use what is called a brominator. A brominator is an automatic bromine distribution system, but in no case it is controlling pH and T A of

water. Thinking their system is completely automatic, users of those systems of ten neglect to test their water. Moreover , make sure that your heat pump installer has modified the circuit of your brominator in a manner to prevent it from pouring out its concentrated solution of bromine into the pool heat pump. (See p.7)

3) Sodium hypochlorite (liquid chlorine)

Liquid chlorine is completely soluble in water and does not leave any residue in pool water, but it decomposes rapidly , even when stored, and require usage of a stabilizer like cyanuric acid. As it is alkaline, it contributes to raise pH and TA. High pH and TA can contribute to the formation of a deposit of limestone on the condenser of the heat pump, creating an isolating layer on the heat exchanger and reducing the heat pump efficiency .

4) Calcium Hypochlorite (granular or stick chlorine)

Granular chlorine is easy to use and dissolves rapidly . On the other hand, it increases pH, T A and calcium hardness significantly . Like with liquid chlorine, high calcium hardness, pH and T A can contribute to the formation of an isolating layer on the heat exchanger reducing the heat pump efficiency .

5) Salt Generated Chlorine

A salt chlorinator produces bleach and other components through the electrolysis of salted water. The proccess does not affect pH nor T A. However , users of those systems must test their pool water on a regular basis since pH and T A may vary because of other factors.

Salt concentration must also be tested because a salted solution contains ions that may corrode the cupro-nickel heat exchanger. Do not put more salt in your system than the

quantity recommended by the manufacturer of the salt chlorinator and do not exceed the recommended concentration. Usually , if the water tastes salted, it contains too much salt

and can damage the heat exchanger of the pool heat pump.

NOTE: Other types of sanitizers exist; all of them have their advantages and inconveniences. What is truly important to keep in mind is that pool water is something that should be maintained regularly and that should be balanced according to standards established throughout the pool and spa industry .

Page 17

What to do?

The purpose of maintaining the water of your pool is not only to protect the swimmers, but also to improve the working conditions of your pool equipment, particularly of your pool heat pump to increase its durability and its efficiency . To achieve this goal, the user must:

1. T est pool water regularly (chlorine or bromine, pH and total alkalinity);

2. Balance the pool chemistry within the level of the standards using the appropriate products;

3. Protect the pool heat pump whenever the water should be beyond the standards.

1) T esting

We highly recommend checking the level of chlorine or bromine, and the level of pH and T A at least once a week. Moreover , we suggest that you have your water tested professionally once a month, particularly the following variables:

· Calcium hardness: a low calcium hardness level implies corrosive water that can damage your pool heat pump. A high level of calcium hardness contributes to the formation of deposits on the surface of the heat exchanger reducing the efficiency of the pool heat pump;

· T otal dissolved solids: a high total implies a tendency of the water to corrode, therefore gradually destroys the pool equipment;

· Copper level: a high copper level can indicate a degradation of the cupro-nickel heat exchanger of the pool heat pump. So this can be considered as a warning urging you to verify the pool water more often. For the users of copper algaecides, a higher level of copper is normal; but verify if there is no gray-black stain deposit indicating the saturation of the water in copper and a possible degradation of the heat exchanger;

· Stabilizer (cyanuric acid): a high level of cyanuric acid can damage the equipments and, especially , is toxic for the swimmers.

2) Balancing

According to the levels given by the test results and according to the volume of water of your pool, always balance the pool water in a manner that meets the standards. Y our swimming pool service company can help you choose the proper chemical products and the appropriate quantities. Always carefully follow the instructions given by the chemical products suppliers. Never pour more into the water than prescribed.

Warning: any chemical product, acid or basic, is susceptible of provoking the degradation of the heat exchanger of your pool heat pump. Never pour any chemical product into the water intake (skimmer) of your pool to prevent the product from damaging your pool heat pump.

3) Protecting the Pool Heat Pump

If you observe that your pool water is beyond the established standards, we urge you to shut down your pool heat pump, to divert the water from it and to disconnect it from the plumbing, as described in the section “Maintenance”, p1 1. Af ter, wash the heat exchanger using tap water .

QUESTIONS AND ANSWERS

1) Is it possible that my pool is losing water since my pool heater was installed?

-Y our pool is not losing water , but because the pool water is at a higher temperature, there is more evaporation. When the difference of temperature between the pool water and the surrounding air is increased, more evaporation happens.

2) Some water drops beside my pool heater, does my pool heater have a leak?

-It probably does not. The water droping from your pool heater must come from condensation of the humidity on the evaporator of your pool heater, just as condensation forms on a cold water glass for example. But, if you really think a leak could be present in your pool heater and want to be sure, you can stop the filter pump and the pool heater, or stop the pool heater and use the by-pass set of valve to prevent water from accessing your pool heater . Wait until the water evaporates beside the pool heater and have the water circulates again into the pool heater without putting the pool heater on. If water drops, it comes from a leak, not from condensation.

3) My pool heat pump indicates a temperature that is different from the temperature indicated on my pool thermometer. Does my pool heat pump have a problem?

-Chances are that it does not. Y our pool heat pump features calibrated digital control and sensors. Most of the time, the problem comes from the pool thermometer. Even though the mercury thermometer is precise, its box is not and the thermometer is often not in line with the graduations written on the box. In this condition, the thermometer reads a temperature higher or lower than the real pool temperature. T o measure the temperature of water , you can use a mouth thermometer on which the graguations are written directly .

-When the pool features a bottom drain, it is possible that the pool heater shows a temperature 1 or 2 degrees lower than what is measured on surface. This situation is normal since the water at the bottom of a pool is always cooler than on surface.

4) Since the installation of my pool heat pump, the pressure in my filter pump has risen, is it normal?

-Y es. The new heat pump, as well as the new tubing, is an added resistance to the water flow. Therefore, it is normal to have a rise of the pressure of 5 to 7 psi after the installation of a new pool heat pump.

5) Why isn’t the pool water heating as my pool heat pump is working?

-3 cases exist as the pool heat pump is functioning:

The heat pump provides more energy than the pool is losing, the temperature rises. The heat pump provides as much energy as the pool is losing, the temperature is stable. The heat pump provides less energy than the pool is losing, the temperature lowers.

We should not forget that the pool heat pump efficiency varies with the operation conditions and that the energy losses of the pool are relative to the outdoor temperature, to the wind, to the size of the pool and to many other factors.
