❸ Use
• Never run the circula ng pump (depending on the model) without water. The circula ng
pump is very quiet when it starts up; you may not hear it running.
3.1 I Opera ng principle
Your heat pump uses the calories (heat) from your home's hea ng to heat up your pool's water.
The heat is exchanged through a series of pipes; the home's hea ng water circulates through the exchanger's body and
the pool water circulates through the pipes.
Tips: improve your pool's temperature rise and maintenance
• Cover the basin 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.
• An cipate the commissioning of your pool far enough in advance before you use it.
• For the temperature rise, set the fi ltra on pump to con nuous opera on (24/24).
• To maintain the temperature throughout the season, run "automa c" circula on for at least 12 hours/
day (the longer this  me the longer the appliance will have enough opera ng range to heat up)

: pool water by-pass valve (secondary circuit)
: pool water outlet valve (secondary circuit)
: hea ng water inlet valve (primary circuit)
: hea ng water outlet valve (primary circuit)
• Check that the hydraulic correc ons are correctly  ghtened and that there are no leaks.
• Check that the device is fully stable.
• Posi on the valves as follows: valves A and C fully open, valve B closed.
• Start the fi ltra on pump.
• Check that the pool water is fl owing through the exchanger,
• Open valves D and E fully,
• Check that the hea ng circuit is fi lled and vented,
• Connect the regula on to the power supply and turn it on,
• Adjust the temperature setpoint.
• A er the start-up steps for your exchanger:
- Check that there are no leaks,
- Check that the circula ng pump stops opera ng when the setpoint temperature is reduced or when the regula on
is switched off and when the fi ltra on is stopped.
- Check that the exchanger is no longer irrigated with water by the hea ng circuit when the fi ltra on is stopped and
that there are no pool water hea ng requests.
Tips: choosing the regula on module for a Heat Line N
• 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 hea ng is requested and fi ltra on is
opera onal,
• It must stop irriga ng the primary circuit once the pool has reached the desired temperature.
Tips: restar ng the circula ng pump a er a long shutdown period
• The circula ng pump is equipped with an self-cleaning system designed to minimise the eff ects of fouling.
• 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 circula ng pump.

❹ Maintenance
4.1 I Wintering
• Wintering is vital to prevent the condenser breaking due to freezing. This is not covered by
the warranty.
• To avoid damaging the electrical box with condensa on, do not fully cover it.
• Only the plug's seal ensures water  ghtness. Replace it without using hemp! To ensure a
water ght seal and avoid damaging the threads, do not over ghten the plug + seal assembly.
• Power down the regula on,
• Cut the water circula on in the primary and secondary circuits,
• Drain the primary circuit (pay a en on to the water temperature; wait un l it cools down to avoid any risk of burns):
- Close the insula on valves D and E (see § “2.2 I Hydraulic connec ons”),
- Open the drainage valve,
• Drain the secondary circuit:
- Close valves A and C (see § “2.2 I Hydraulic connec ons”),
- Unscrew the connectors to drain the exchanger,
- Tighten the connectors slightly again when the exchanger is empty.
4.2 I Maintenance
• It is recommended that the device be general serviced at least on a yearly basis to ensure
proper opera on, maintain performance levels and prevent some poten al failures. These
opera ons are carried out at the user's expense, by a technician.
• Never disassemble the exchanger body.
4.2.1 Maintenance to be carried out by a qualifi ed technician
• Make sure that the appliance's pipe fi  ngs are property  ghtened.

• If the problem con nues contact your reseller.
•
If the problem con nues contact your reseller.
: Ac ons reserved for a qualifi ed technician
5.1 I Device behaviour
The device does
not start hea ng
straight away
• When the setpoint temperature is reached, the appliance stops hea ng: the water temperature
is higher than or equal to the setpoint temperature.
• When the water fl ow rate is zero or is not enough, the appliance stops: check that the water is
circula ng correctly in the exchanger and that the hydraulic connec ons are correct.
• It may be that the appliance has detected an opera ng fault (see § “5.2 I Error code display”).
• If you have checked these points and the problem persists: contact your reseller.
The device is not
working
• If there is no display, check the supply voltage and the F1 fuse and replace it if necessary
(see § “5.3 I Replacing the electrical box fuse (depending on the models)”).
• When the setpoint temperature is reached, the appliance stops hea ng: the water temperature
is higher than or equal to the setpoint temperature.
• When the water fl ow rate is zero or is not enough, the appliance stops: check that the water is
circula ng correctly in the appliance.
• It may be that the appliance has detected an opera ng fault (see § “5.2 I Error code display”).
The device is
working but
the water
temperature does
not increase
• It may be that the appliance has detected an opera ng fault (see § “5.2 I Error code display”).
• Check that the automa c fi lling valve is not stuck in open posi on; 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.
• Check that the appliance is the right size for this pool and its environment.
There is noise in
the circuit
• Iden fy whether the noise is coming from the circuit or the circula ng pump.
• If the noise is coming from the circuit:
- There must be air in the circuit; bleed the installa on.
- The water fl ow is too high; reduce the opera ng speed, see § “3.4.4 Opera on of the
circula ng pump on Heat Line +”
• If the noise is coming from the circula ng pump:
- There is air in the circula ng pump; let it run. It will bleed itself.
- The water fl ow is too low; increase the pressure in the primary circuit and/or check the air
volume in the expansion chamber (if installed)
The pool water
is ho er than
requested
• The circula ng pump is not opera ng correctly. Check that it stops when the setpoint
temperature is reached.
• Another circula ng pump is pushing on the primary circuit. In this case, provide a solenoid valve
on the output from the primary circuit managed by terminals 19-20 (see § “2.3.1 Connec ng an
external command to supply the primary circuit”).
The device trips
the circuit breaker
• Check that the circuit breaker is correctly dimensioned and that the cable sec on used is
the right one (see § “1.2 I Technical specifi ca ons”).
• The supply voltage is too low; contact your electricity supplier.
