5.2. REQUIREMENTS AND PREVIOUS OPERATIONS

All models:

• Check the place where the equipment is to be located is strong enough to support the weight of this.
• To improve the distribution of weights, the unit will be placed on a bench according to the designer's criteria.
  Always place the machine in a vertical and level position.
  The PROHEAT II equipment is designed to work:

Standard and chiller models: Outdoor installation.
O Indoor models: Indoor installation.

• A space must be provided around the equipment for its maintenance and operation, in addition to checking that the air inlet and outlet are not obstructed.
• It is not advisable to place the machine 1.5 meters above the sheet of water, or 3 meters below.
• During operation, condensation water produced by the evaporator may appear, for which the machine has an evacuation outlet identified on one side.
• To avoid any corrosive process in the evaporator battery, the unit can not be installed in an acidic or alkaline environment.

In addition, the Indoor models must take into account the following:

• The arrangement of the air ducts must be of an adequate size and the loss of load of the ducts must not exceed the available pressure of the installed fans.
• The aspiration and impulsion of the equipment will be installed at a sufficient distance between them so that undesired recirculation can not occur.
• It is also desirable to provide a removable door or plate in the outdoor air intake duct to be able to check its condition and proceed to clean any dirt that may be trapped in the air inlet of the unit.
• Leave at least 1 meter of unused space around the equipment to facilitate personnel access and maintenance operations.

The primary hydraulic circuit, used to heat the pool water, must not be galvanized steel or aluminum. Corrosion problems may appear due to galvanic corrosion

• The standard and chiller models have been designed for outdoor installation (never INDOOR).
  The Indoor models have been designed for installation indoor (never outdoors). THE WARRANTY WILL BE Void IF THIS CONDITION IS NOT FULFILLED

5.3. OPERATING CONDITIONS

Water physical and chemical parameters must be in between:

PH 7,2 a 7,8
Residual chlorine 1 a 2 ppm
Alkalinity 80-125 ppm
Total dissolved solids .. < = 3000mg / l
Hardness 200-300 ppm

The limits established for working conditions in order to guarantee the proper operation of the equipment are:

Minimum outside temperature: 0°C.
Maximum pool water temperature: 40°C.
- Minimum water-cooling temperature. 20^ C (Only CHILLER MODELS, for lower operating temperatures, consult Fluidra Comercial)
Maximum input water pressure: 3,5 bar.
Maximum conditions of the technical room... 35^ / 90% RH (INDOOR MODELS).

The operating conditions will affect the output of the equipment.

The operating conditions will influence the performance of the equipment and the power data provided in the data sheet may vary, if these placement recommendations do not occur. It is extremely important that the minimum water flow indicated in the technical sheet is guaranteed. If this flow is reduced, the compressor dew point is higher, and the energy consumption is higher.

In INDOOR equipment, under certain conditions of temperature and humidity, condensation may appear on the outside of the equipment. This is normal and does not affect the correct operation of the equipment.

Example of installation of Proheat II equipment with Axial fan for outdoor installation only:

V1-V2-V3: By-pass valves. (Required for all models)

V4-V5: Adjustment valves

Installation example of the Proheat II INDOOR equipment with centrifugal fan for indoor installation only:

It is necessary to make the duct network so that the air collected by the machine to operate the refrigeration circuit, never return to the machine, and must be expelled to the street. The machine must be located exclusively inside.

In this example of installation, it can be seen that the technical room is perfectly ventilated through a grid of sufficient size to guarantee the correct flow of air through the evaporator. And that the driving air is driven outside.

If the distance between the machine and the outside air is too high, a duct can be connected directly to the evaporator inlet, as long as the nominal air flow of the equipment is guaranteed. The limit of loss of load of these models Indoor is 120Pa , and if this value is not respected, the heat pump can be damaged. For greater load losses available, consult Fluidra Comercial.

5.4. CONDENSATION DRAIN

The AIRPOOL dehumidifier will naturally generate condensation water. This water will be gathered inside the machine and will come out through a condensation drain located on the frame of the equipment. The installation must have a drain to evacuate such condensation water.

The condensation drain is identified by this decal on the machine:

It is advised to install a siphon in the condensation drainage to prevent liquid and odours returns.

6. CONTROLLER

6.1. MAIN FUNCTIONS

The NA8981 regulator is ideal to control air-water heat pumps with on or two compressors. It is equipped with temperature probes (water input and output, evaporator defrost, compressor discharge and ambient temperature). It also has safety sensors (high and low pressure switches, a flow switch to control water flow through the equipment, compressor consumption meter and internal fan thermal switch).

Its main functions are shown below:

• TEMPERATURE DISPLAY AND CONTRILLING: The display shows the water temperature at all times and the user can choose the setpoint between the operating limits. The settings of the temperature probes can also be displayed.
• AUTO DEFROST CONTROLLING: It has an optimized design of logical defrost controlling and can defrost effectively in order to ensure the machine can run normally at low temperature.
  EXHAUST TEMPERATURE PROTECTION: If the discharge temperature of the compressor is too high, the machine will stop and an alarm will appear on the display (A24 or A25).
• HIGH AND LOW PRESSURE PROTECTION: The machine is equipped with high and low pressure switches that stop the machine and displays an alarm if either pressure exceeds its limits (A11, A12, A13 or A14).
• DIFFERENT PERIOD OF OPERATION: The regulator has two operating modes: "Heating" and "Schedule programming". In the "Heating" mode, the machine will operate until the water temperature reaches the setpoint temperature set by the user. In the "Schedule programming" mode, as many as three machine operating periods can be scheduled (See STARTING BASIC OPERATION).
  PHASE MISSING PROTECTION AND SEQUENCE PROTECTION: When any of the 3 phases supplying the equipment fails or the 3 phases have been connected incorrectly, the machine will stop and an alarm will appear on the display (A91).
• DISPLAY OF COMPRESSOR CONSUMPTION AND PROTECTION VERSUS EXCESS CONSUMPTION: The regulator shows compressor consumption (A) on the screen. If consumption is excessive, the machine will stop and an alarm will appear on the display (A93-A94).
• SEQUENTIAL COMPRESSOR START-UP: The regulator starts up the compressors in sequence to avoid excess peak power use in the line.
• WINTER ANTI-FREEZE PROTECTION: This protection allows the regulator to recirculate the water by starting up the water treatment pump so the water does not remain in the frozen pipes (See PROTECTION SYSTEMS).
• TRIP CIRCUIT: The regulator uses this function to protect the machine in the event of faults affecting the contactors or an error in the supply line.
• EMERGENCY OPERATION FUNCTION: If communication fails in the LCD display, the machine can operate with the most recently saved settings.
• EMERGENCY STOP: The equipment is prepared with an emergency push-button with a manual interlock and reset that cuts off the general power to the machine if pressed.

MINIMUM VOLTAGE STOP: The machine is protected against severe voltage drops in the line by an automatic cut-off device in the main circuit breaker; this device triggers when voltage drops to a certain level below the nominal voltage.

• Observation1 : When F24=1, this means there is only one circuit. Therefore, none of the System 2 inputs/outputs can be used. And no error codes will be displayed. Also, the error codes A13, A14, A23, A25, A27 will not be shown.

The regulator has 4 operating modes, depending on the heat pump model: Cool, Heat, Auto and Manual selection of the operating mode. The available operating mode is controlled by parameter F29.

F29 = 0 only Auto mode (C / H)

F29=1, only Heat mode (C/H).

F29 = 2 only Cool mode (C / H)

F29=3, Manual selection of the operating mode (M).

In the Cool mode, the machine starts cooling when the probe temperature is higher than the "Temperature setpoint + Temperature differential" and it stops cooling when the temperature is lower than the "Setpoint temperature - Differential temperature".

In the Heat mode, the machine starts heating the water when the probe temperature is lower than the "Temperature setpoint + Temperature differential" and it stops heating when the temperature is higher than the "Setpoint temperature - Differential temperature".

In the Auto mode, the machine starts cooling when the probe temperature is higher than the "Temperature setpoint + Auto mode temperature differential" and it stops cooling when the

temperature is lower than the "Setpoint temperature". The machine starts heating when the probe temperature is lower than the "Temperature setpoint - Auto mode temperature differential" and it stops heating when the temperature is higher than the "Setpoint temperature".

6.4.2. HEAT MODE

Start-up process:

Start-up conditions: Water intake temperature < (Setpoint temperature - Temperature differential); and the Compressor stop time ≥ Compressor delay time.

Start-up conditions: Water intake temperature < (Setpoint temperature + Temperature differential); and the Compressor stop time ≥ Compressor delay time

Start-up conditions: Water intake temperature < (Setpoint temperature - Auto mode temperature differential); Compressor stop time ≥ Compressor delay time, then it enters Heat mode.

If the water intake temperature > (Setpoint temperature + Auto mode temperature differential); and the Compressor stop time ≥ Compressor delay time, then it enters Cool mode.

Stop process:

Compressor 1 stops, Compressor 2 stops 10s later, the fans stop and the water pump stops 30s later.

6.4.5. DEFROST FUNCTION

The controller will supervise the temperature in the evaporators when the machine is in heating mode, and decide whether need to defrost according to the working time of the machine in that continuous low temperature state. In other words, the defrosting calculagraph begins to count when the machine evaporator temperature is lower than

"defrost start temperature", and turns on the defrosting when the value of time reaches "defrost start time". The calculagraph will be cleared if the evaporator temperature is higher than "defrost start temperature" when counting, and it begins to count again when the evaporator temperature is lower than "defrost start temperature". In other words, the value of defrosting

No.	DEFINITION
1	FILTER PUMP
2	SINGLE PHASE
3	THREE PHASE
4	PROHEAT II
5	SCHEDULE TIMER

calculagraph shows the continuous low temperature working time of the machine (For 2 compressor systems as long as a compressor system satisfies the conditions for defrosting, the other system will also defrost).

DEFROST SEQUENCE:

The controller can check the defrosting effect with the external air temperature. If the external air temperature is higher than the "defrost end temperature", the controller will turn off the function of defrosting. If the defrosting time is over "max defrost time", the controller will turn off defrosting forcibly. The process explained above can only run in heating state, in other words, the controller will not turn ondefrosting in non-heating mode. After reaching the conditions for stop defrosting in compressor 1, this compressor 1 will wait compressor 2 to reach those conditions. As soon as compressor 2 stops, the heating mode will start for both compressors at

the same time (they will have a delay between them).

Remark: when pipe1 sensor faults, pipe2 temperature sensor will be used.

when pipe1 and pipe2 sensor fault : The system will check external air temperature, if external air temperature < F35 and the machine run time > Defrost start time, the machine will defrost ; if defrost time > Max defrost time then defrost will stop

6.4.6. WATER PUMP CONTROL

The controller can choose whether to use water pump or not (F40), 0 means no water pump function, 1 means control the water pump.

When the water pump is running, the compressor starts some time after (F41) and when the compressor stops, the water pump stops some time later (F42). When we have the external alarm or the over-probation time alarm, the water pump is switch off immediately. The compressor won't start until the water pump achieves the working time of F41. When the machine stop running, the water pump follows the below loop: F43 stop, F44 run.

6.4.7. FAN OPERATING CONDITIONS

When F27=-10, the fan will run at normal speed. In the PROHEAT II model, the fan will rotate at this fixed speed.

When F27-10,

If the ambient temperature ≤ F27(20^) , the fan will run at maximum speed.

If F27 (20^) < Ambient temperature < F28 (45^) , the fan will run at minimum speed.

If ambient temperature ≥ F28 (45°C), the fan will run at maximum speed.

The PROHEAT II machines run at normal speed F27=-10°C.

6.4.8. REMOTE SWITCH

When the remote switch is closed:

If the unit is running. The unit works normally

If the unit is stopped. The unit stops.

When the remote switch is open:

If the unit is running. The unit stops and the screen display "OFF".

If the unit is stopped. The unit stops.

6.5. PROTECTION SYSTEMS

6.5.1. COMPRESSOR DELAY PROTECTION

The compressor delay time is adjustable (F21) and set to 5 minutes by default. The regulator uses this time setting to prevent continuous ON/OFF cycles. When the compressor has been running and then stops, the next time it is started up, the regulator will check that the period of time has passed before starting it up again; if not, it will wait for 5 minutes until the compressor starts again. If the machine has just been started up, there will be a 5-minute wait before the compressor starts.

6.5.2. PHASE CONTROL

When the 3 phases of the machine are connected incorrectly or a fault is detected in any of the phases, the machine will stop and the error code "A91" will be displayed.

6.5.3. OVER CURRENT PROTECTION (If 23=0, disable)

Consumption is checked three seconds after the compressor starts up; if the current > F23 for 5 seconds, the machine will stop and error "A93" will be displayed.

6.5.4. WATER FLOW PROTECTION (F46=0, disable)

After 30 seconds with the water pump ON, the flow switch status is checked; If after another 5 seconds the status of the flow switch is OFF, the machine is stopped and display the error code "A15".

6.5.5. HIGH PRESSURE PROTECTION

It is a normally closed switch in the controller. The controller checks during 5 seconds the status of the high pressure switch and it will take another 5 seconds to act. If it is open, the machine will stop. If at any time, the status of the high pressure switch is closed, the machine will run automatically. But if within an hour we have 3 alarms of this protection, the system will be blocked in alarm status and display error code "A12" or "A14". In order to unblock the system, manual reboot is needed.

6.5.6. LOW PRESSURE PROTECTION

It is a normally closed switch in the controller. During the defrosting and in the first three minutes after switching on the machine, the status of the low pressure switch is not checked. In o not check the low pressure signal;

The controller checks during 5 seconds the status of the low pressure switch and it will take another 5 seconds to act. If it is open, the machine will stop. If at any time, the status of the low pressure switch is closed, the machine will run automatically. But if within an hour we have 3 alarms of this protection, the system will be blocked in alarm status and display error code "A11" or "A13". In order to unblock the system, manual reboot is needed.

6.5.7. EXHAUST TEMPERATURE PROTECTION

When exhaust temperature is higher than F45, the machine stops running, and shows the error code "A24" or "A25". As soon as exhaust temperature drops to (F45 - 10^) , the machine will run again (each compressor works independently).

But if within an hour we have 3 alarms of this protection, the system will be blocked in alarm status. In order to unblock the system, manual reboot is needed.

6.5.8. THE WATER TEMPERATURE DIFFERENT IS TOO LARGE PROTECTION

The difference between inlet and outlet water temperatures will be controlled by the regulator for 5 seconds. If the difference is higher than F72, error code "A44" will appear 5 seconds later and the compressor will stop. If this protection triggers 3 alarms in one hour, the system will lock down in alarm status. The machine will have to be restarted manually to unlock the system.

6.5.9. LOW TEMPERATURE LIMITS THE COMPRESSOR RUNNING

If externa air temperature is < F26 , the compressors cannot be started (except for defrost protection in winter). Only the electrical heating can be started.

6.5.10. ANTIFREEZE PROTECTION IN WINTER

This feature is not active when the external air temperature is over 3^ . If the water in temperature is below 4^ and the air temperature is below 3^ and the machine is OFF or in stand-by mode the machine will activate the water pump to avoid having the water in the pipes iced (piping broken).

6.5.11. SENSOR FAULT PROTECTION

Pipe 1、Exhaust 1、Pipe 2、Exhaust 2 Sensors work independently in each circuit and display different error codes to distinguish between different systems;

Water inlet temperature sensor fault, stops the machine.

If other temperature sensor faults, close the protection.

Auto test: if the sensor failure is corrected, the unit restarts.

Note : If we get a failure when the machine is working, the water pump will continue working during 5 minutes. Then it will be stop.

7. GENERAL PRECAUTIONS

The installation, start-up and maintenance operations must be performed by qualified personnel.

This equipment should not be installed in inflammable or explosive environments.

The electrical power supply at the main circuit breaker must be switched off before any maintenance work is performed inside the machine.

It is mandatory to use personnel protection equipment, such as goggles, gloves, etc. during maintenance work.

During operation of the unit, it is normal that the condensation produced in the evaporation battery will produce a certain quantity of water which will have to be evacuated. The machine is equipped with a drain for this purpose that must always be unobstructed.

This water condensation doesn't need to be specially treated.

8. CHECKING THE PACKAGING

This equipment comes with RECYCLABLE packaging that can withstand rough transport conditions. However, you should examine the device during installation to ensure there is no damage, thus avoiding any subsequent malfunction.

The MANUFACTURER will not be held responsible in this case

IS VERY IMPORTANT TO KEEP THE PACKAGED EQUIPMENT UPRIGHT, THE PACKAGING HAS BEEN SPECIFICALLY DESIGNED FOR THIS. ALWAYS MAINTAIN IT IN A VERTICAL POSITION.

IF THE UNIT IS DAMAGED, OR THE DELIVERY IS INCOMPLETE, MAKE A NOTE OF IT ON THE CARRIER'S BILL AND IMMEDIATELY MAKE A CLAIM TO THE COMPANY IN CHARGE OF DELIVERY.

Inside the parcel you will find the following elements:

Pool heating equipment

Installation manual.

Warranty.

9. ELECTRICAL CONNECTIONS

The electrical connection must be carried out by the fitter taking the following points into account:

• Please perform the connection according to the circuit diagram included in this manual.
• Place a differential circuit breaker in the general power connection to protect the equipment from possible grounding problems. The differential breaker should be minimum 30mA .
• Differential breaker.
  Automatic or circuit breakers.
• Before connecting the equipment, you must check that the electrical installation is disconnected and that there is no voltage between the power supply phases.
• Connect the lead-in wires to the machine's input terminal.
• Connect the ground wire to the relevant terminal.
• The provision of any legislation in force with respect to any electric lines against direct or indirect faults and contacts must be followed at all times.
• Verify the tightness of all electrical connections.
• You must check that the electrical resistance between the ground and any electrical terminal is over 1 megaohm. If not, the equipment cannot be started up until the electrical loss may be located and repaired.
• If there are fluctuations of the input voltage, it is recommended to install a voltage stabilising system to prevent damaging the equipment.
  The illustration below shows a diagram of a proper connection.

The heat pump should never be operated without the water treatment pump running. Do not interconnect timers or programmers that may leave the unit running after the water treatment pump has been switched off.

Do not change the calibration of the motor protection breakers. If in doubt, contact the distributor.

The heat pump should be connected to a by-pass prepared for that purpose at the exit of the water treatment system and always before any chemical dosing system. If the intake of the dosing system is less than 25cm under the heat pump water outlet, a syphon should be installed. A no-return valve should be installed as an additional safety measure to prevent the return of chemical products to the pump when water circulation is interrupted.

The equipment should never be run without water circulating through the hydraulic system.

Do not place concentrated chemical products in the pool skimmers.

Always respect the hydraulic connection diameters specified for each machine.

A full-flow shut-off valve should be installed on each of the hydraulic elements in the equipment, so that each of these may be isolated if needed (filter cleaning, repairs, replacements, etc.) without the need to drain the circuit.

Anti-vibration dampers should be installed in the inlet and outlet of the machine, in order to avoid vibrations which may cause cracks or breakage in the hydraulic connections.

Do not force the PVC pipes when connecting the equipment to the hydraulic network. This will prevent them from breaking or cracking.

11. START-UP PROCEDURE

When setting-up, the electrical connections, as well as the general power supply and voltage should be verified

• Check that the hydraulics are connected properly.
• Give power to the equipment by connecting the general power switch on the outside of the unit. Once the unit is connected, verify the current absorbed by the phases.
• It is important to note that the equipment comes with a standard crankcase heater and should be under voltage for at least 1 hour before start-up so the oil in the compressor can reach its ideal condition to lubricate the compressor components.
• Three phase machines are equipped with a phase control relay that ensures that the compressor rotates in the right direction. Alarm in the regulator.
• With the machine running, verify the intensities absorbed by the electric motors, making sure they do not exceed the limits mentioned in the technical specification sheet.
• Check that there are no gaps between currents in the various lines, except those caused by single phase circuits.
• High and low pressure switches should be installed in the cooling circuit and verify the refrigerant charge (Refrigerant Charge section).
• Disconnect the ON/OFF switch to stop the equipment.

12. PREVENTIVE MAINTENANCE

You must keep a record of each component maintained as well as the actions or repairs undertaken.

• DISCONNECT THE EQUIPMENT FROM THE POWER SUPPLY before performing any maintenance procedures.
• The surface of the exterior panels may be cleaned with a soft cloth and non-abrasive cleaner.
  The machine has been designed to operate outdoors.
• It is important that the equipment be installed on stable ground and protected from flooding.

Things to take into account:

EVAPORATOR COIL:

The evaporator coil should be kept clean and free of obstacles which may hinder the circulation of air through them. In order to clean it, use water at low pressure and non-abrasive detergents or cleaning liquids made specifically for that purpose.

COMPRESSOR:

Compressor oil must be checked in those unit models provided with an oil viewer.

Make sure the crankcase heater works properly.

Verify that the compressor refrigerates adequately with the circulating gas (verify the refrigerant charge).

Verify that the power consumption has not increased.

Verify that the compressor discharge pressure is not too high and that the intake pressure is not too low.

Verify that the compressor fasteners are not deteriorated.

Verify that no frost develops on the compressor.

CONDENSEN:

Install the chemical product dosifiers "downstream" from the heat pump, at a height lower than the pump itself and always as far away from the pump as possible. Never in the suction pipe of the water treatment pump, since this will damage the condenser.

NEVER place concentrated chemical products in the pool skimmers; this will damage the titanium condenser.

In climates subject to sporadic freezing temperatures, the water can be circulated by the water treatment pump to ensure that the water temperature remains above freezing (0^) .

In the event of persistent freezing conditions, all the water treatment and heating system components should be completely drained. Draining is performed by removing the drain plug on the side of the condenser

FAN:

Verify the flows of the fan each year.

Clean the louvers of the fan as well as the protection grill regularly.

ELECTRICAL PANEL:

Check all electrical connections.

Verify that there is no over-heating of the electrical terminals.

Check that the safety systems are working correctly.

Verify that the thermostat or main control operates correctly and verify the temperature with a mercury thermometer (probe calibration).

Potential effects on the environment or human health of the hazardous elements it may contain.

PVC

The most widely used plasticizing agent in applications of PVC is DEHP (Diethylhexyl phthalate). Trials carried out in several laboratories show that it does not pose a risk to human health in the concentrated levels used in finished products, according to reports from BUA in Germany (Advisory Committee on Existing Chemicals of Environmental Relevance) and the BGA (Health German Authority), amongst others. The results from such trials, together with data obtained from biodegradatio studies, confirm that DEHP cannot be considered hazardous for the environment. All additives used in PVC formulations and, thus, in food applications are fully regulated both at European and Spanish level.

In Europe, there is the EU 90/128/EEC Commission Directive subsequently amended by EU 95/3/EEC. In Spain, there is the Spanish Royal Decree 1125/1982 of 30th of April, ratified by the Spanish Royal Decree 1042/1997 of 27th of June of that same year.

Modern technology applied to PVC production plants for some years allows us to declare that such plants do not pose a threat to the environment, the Life Cycle Analyses (LCA) show that the environmental impact of PVC is equivalent to that of other materials or even more favourable.

TITANIUM

Health effects. Elemental titanium and titanium dioxide are of a low order of toxicity. Excess exposure in humans to titanium dioxide due to inhalation can result in mild alterations in the lungs.

Effects of overexposure to titanium powder. Dust inhalation may cause tightness and pain in chest, coughing, and difficulty breathing. Contact with skin or eyes may cause irritation. Entry pathways: Inhalation, skin contact, eye contact.

Carcinogenicity. The International Agency for Research on Cancer (IARC) has listed titanium dioxide within Group 3 (The agent is not classifiable as to its carcinogenicity to humans.)

Environmental effects. Low toxicity. No negative environmental effects of titanium have been reported.
