❷ Installation 2.1 I Selecting the location • The appliance must be installed in a technical room ventilated, dry and without stored pool treatment products. • The appliance must be installed before any water treatment system. • Install the appliance as close as possible to the heating source (boiler, heat pump, geothermal, solar-powered heating, etc.), • If the appliance cannot be installed beside the heating source: - Provide for the dimensioning of the pipes and primary and secondary circuits in relation to the water flow rate, the losses of load and the distance, and insulate them thermally. - Install a more powerful circulating pump (contact a qualified professional for its dimensioning). • If the exchanger is a long way from the filter, for the pool circuit use a system of Ø50 or Ø63 pipes (if the overall length of the circuit is greater than 30 metres). If the pipes are installed underground, they should be in protective sleeves. • Preferably, the exchanger should be installed at the low point so that it is always full of water. • The water treatment system must be installed at a low point to avoid chlorine being returned to the exchanger. • Leave at least 80 cm free space around the appliance to facilitate its installation and maintenance, • The pipes must not be supported by the exchanger. • The appliance must be secured horizontally to the wall of the technical room: - Bare Heat Line: using brackets (not included). - Heat Line Plus and without circulating pump: using the holes at the back of the switch box and 4 screws (not included). IMPORTANT: Do not attach the appliance using adhesive tape. Dimensions for attachment of Heat Line Plus and Heat Line without circulating pump EN 6
2.2 I Hydraulic connections • Respect the hydraulic connection direction (see the indications on the exchanger tank). • Correctly tighten the hydraulic connections and check for leaks. • Check that the pipe system is cleaned before connecting anything. Tip: calorie exchange optimisation • The water from the heating source must be at constant temperature. • Respect the water flow direction in the exchanger. If the installation requires it, you may reverse the pool's water circulation direction in the exchanger, see § « 2.2.3 Adapting the heat exchanger to the direction of water flow (depending on the model) ». 2.2.1 Connection of the heating system connection (i.e. primary circuit) • The primary circuit's spur must be upstream of any valves or pumps. • Bare Heat Line: if the heating source is equipped with a circulating pump, an accumulator or relay logic can be added to switch off the circulating pump and the heating source. If this is not possible, provide a system to prevent any primary circuit water from returning to the exchanger when there is no water circulating in the secondary circuit. • The connection must be: - Made in insulated pipes, - Fitted with a safety valve (pressure limited to 3 bars) and a correctly-dimensioned expansion chamber, - Use pipes fitted with automatic drains at their high points. 2.2.2 Pool system connection (a.k.a. secondary) • No 90° bend is to be directly fitted to the input or the output of the exchanger. • Leave at least 25 cm of straight pipe to prevent any chatter of the flow switch armature. • The connection must be made: - Using PVC pipes Ø50 minimum, - Via a bypass (recommended to simplify maintenance and mandatory if the water flow rate of the pool system is greater than 22 m³/h). 2.2.3 Adapting the heat exchanger to the direction of water flow (depending on the model) • Remove the cover from the switch box and disconnect the regulator's two connectors to remove the cover, • Unscrew the 4 retaining screws from the switch box's support. • Rotate the heat exchanger and circulating pump 180 °. • Position and secure the switch box support using the 4 retaining screws. • Reconnect the two connectors to the regulator. • Reposition the switch box cover and secure it with the screw. 7 : Pool water inlet valve : Pool bypass valve : Pool water outlet valve : Heating water inlet valve : Heating water outlet valve : Exchanger body : Pool circuit secondary) : Heating circuit (primary) : Circulating pump : Automatic purge

❸ Use • Never run the circulating pump (depending on the model) without water. The circulating pump is very quiet when it starts up; you may not hear it running. 3.1 I Operating principle The heat pump uses the calories (heat) from the home's heating to heat up the pool's water. The heat is exchanged through a series of pipes: the home's heating water circulates through the exchanger's body and the pool water circulates through the pipes. Tips: improve the pool's temperature rise and maintenance • Cover the pool with a sheet (bubble canopy, canvas, etc.) to prevent heat loss. The closer the heat source is to the exchanger, and the exchanger is to the pool, the less heat will be lost. • Anticipate the commissioning of your pool far enough in advance before you use it. • For the temperature rise, set the filtration pump to continuous operation (24/24). • To maintain the temperature throughout the season, run "automatic" circulation for at least 12 hours/day (the longer this time the longer the appliance will have enough operating range to heat up) 3.2 I User interface presentation (depending on the model) Display screen (default: water temperature measured) "On/off" button Value setting buttons Steady Flashing Off "On/off" “On/off” Appliance powered up / No electrical • Timed before operation • No water circulation in the secondary circuit (less than 1.1m³/h) Heating light Heating in progress Tips: using the user interface • The temperature is regulated by degrees. • Hold down the buttons to scroll through the values quickly. • The setpoint adjustment range is between 2° and 40°C. • The maximum temperature may be lowered to protect the pool liner (see § 3.2.1 “Modifying the maximum setpoint”). 3.2.1 Modifying the maximum setpoint • Switch off the regulator (the "ON" light goes off and the pool water temperature is displayed), • Press and simultaneously for 5 seconds: "PA" is displayed, • Press , then enter the value "80" with or (code to access the "Settings" menu), • Press to confirm: "PA" is displayed, • Press and simultaneously for 5 seconds: "/1" is displayed, • Press to scroll through each parameter until "r2" is displayed, • Press , the current "r2" parameter value is displayed, • Press or to modify the maximum setpoint value, then press to validate this new value, • Press the and keys at the same time for 5 seconds to return to the pool water temperature display. 9 supply No need for heating
3.3 I Operation • Never run the circulating pump (depending on the model) without water. The circulating pump is very quiet when it starts up; you may not hear it running. • Never run water through the primary circuit when there is no water running through the secondary circuit. • The flow rate must be adjusted slowly to avoid hammering. : Pool water inlet valve (secondary circuit) : Pool water bypass valve (secondary circuit) : Pool water outlet valve (secondary circuit) : Heating water inlet valve (primary circuit) : Heating water outlet valve (primary circuit) • Check that the hydraulic connections are correctly tightened and that there are no leaks. • Check that the appliance is stable. • Position the valves as follows: valves A and C fully open, valve B closed. • Start the filtration pump. • Check that the pool water is flowing through the exchanger, • Open valves D and E fully, • Check that the heating circuit is filled and vented, • Connect the regulation to the power supply and turn it on, • Adjust the temperature setpoint.. • After the start-up steps for your exchanger: - Check that there are no leaks, - Check that the circulating pump stops working in case the setpoint temperature is reduced, the regulation is stopped or the filtration is stopped. - Check that the exchanger is no longer irrigated with water by the heating circuit when the filtration is stopped and that there are no pool water heating requests. Tip: Tips: choosing the regulation module for a Bare Heat Line • It must reference the input temperature of the pool water in the appliance. • It must give the command to irrigate the primary circuit only if heating is requested and filtration is operational, • It must stop irrigating the primary circuit once the pool has reached the desired temperature. Tip: Restarting the circulating pump after a long shutdown period • In the event of a blockage, an indicator lights up (see § « 5.2 I Error code display »). In this case, use a screwdriver to manually release the blockage through the central hole provided in the circulating pump. EN 10
3.4 I Additional functions 3.4.1 Setting the setpoint on Heat Line Plus with and without circulating pump To display and modify the set point value, press or . 3.4.2 Operation of the circulating pump on Heat Line Plus Tip: Choosing the right operating mode • By default, the circulating pump is programmed to "Proportional speed 3 pressure". We recommend that you keep this mode, which is suitable for most installations. • If, however, your appliance is close to the boiler, you may lower the speed to speed 1 or 2 (see § « 3.4.2 Operation of the circulating pump on Heat Line Plus »). • Press to scroll through the operating modes and the speeds associated with them.

❹ Maintenance 4.1 I Winterising • Winterising is vital to prevent breakage due to freezing. This is not covered by the warranty. • To avoid damaging the switch box with condensation, do not fully cover it. • Only the plug's gasket ensures water tightness. Replace it without using hemp. • To ensure good water tightness, do not tighten the plug + gasket set excessively and do not damage the thread. • Power down the regulation, • Cut the water circulation in the primary and secondary circuits, • Drain the primary circuit (pay attention to the water temperature; wait until it cools down to avoid any risk of burns): - Close the isolation valves D and E (see § « 2.2 I Hydraulic connections »), - Open the drainage valve, • Drain the secondary circuit: - Close valves A and C (see § « 2.2 I Hydraulic connections »), - Unscrew the connectors to drain the exchanger, - Tighten the connectors slightly again when the exchanger is empty. Tip: Restarting the circulating pump after a long shutdown period (depending on the model) • If a blockage occurs, lights appear on the circulating pump, see § « 5.2 I Error code display ». 4.2 I Maintenance • It is recommended that the appliance undergo general servicing at least on a yearly basis to ensure proper operation, maintain performance levels and prevent any possible failures. These operations are carried out at the user's expense, by a qualified technician. • Never disassemble the exchanger body. 4.2.1 Maintenance to be carried out by a qualified technician • Make sure that the appliance's pipe fittings are property tightened. • Only for Heat Line Plus and Heat Line without circulating pump: - Check the electrical mechanism. - Check the ground connection, - Check that the electrical cables are correctly tightened and connected and that the switch box is clean. EN 12
❺ Troubleshooting • Before you contact the retailer, carry out these few simple checks using the following tables if a problem occurs. • If the problem is not resolved, contact your retailer. • : Actions to be performed by a qualified technician only 5.1 I Appliance behaviour • When the setpoint temperature is reached, the appliance stops heating: the water temperature is higher than or equal to the setpoint temperature. • When the water flow rate is zero or is not enough, the appliance stops: check that the water is circulating correctly in the exchanger and that the hydraulic connections are correct. • The appliance may have detected an operating fault (see § « 5.2 I Error code display »). • If you have checked these points and the problem persists: contact your retailer. The appliance does not start heating straight away • If there is no display, check the supply voltage and the fuse. If necessary, replace it (see § « 5.3 I Replacing the switch box fuse (depending on the model) »). • When the setpoint temperature is reached, the appliance stops heating: the water temperature is higher than or equal to the setpoint temperature. • When the water flow rate is zero or is not enough, the appliance stops: check that the water is circulating correctly in the appliance. • The appliance may have detected an operating fault (see § « 5.2 I Error code display »). The appliance is not working • The appliance may have detected an operating fault (see § « 5.2 I Error code display »). • Check that the automatic filling valve is not stuck in open position; this will keep supplying cold water into the pool and will prevent the temperature from rising. • There is too much heat loss as the air is cool. Install a heat insulated cover on your pool. The appliance is working but the water temperature does not increase • Check that the appliance is the right size for this pool and its environment. • Identify whether the noise is coming from the circuit or the circulating pump. • If the noise is coming from the circuit: - Air is trapped in the circuit: purge the installation. - The water flow rate is too high; reduce the operating speed: (see § « 3.4.2 Operation of the There is noise in the circuit circulating pump on Heat Line Plus »). • If the noise is coming from the circulating pump: - There is air in the circulating pump; let it run. It will bleed itself. - The water flow is too low: increase the pressure in the primary circuit and/or check the air volume in the expansion chamber (if installed). • The circulating pump is not operating correctly: Check that it stops when the setpoint temperature is reached. • Another circulating pump is pushing on the primary circuit: provide a solenoid valve on the outlet of the primary circuit managed by terminals 19-20 (see § « 2.3.1 Connecting an external command to supply the primary circuit »). The pool water is hotter than requested The appliance trips the circuit breaker • Check that the circuit breaker is correctly dimensioned and that the cable section used is correct (see § « 1.2 I Technical specifications »). • The supply voltage is too low; contact your electricity supplier. 13
