The conditions of installation and use described above have all been met.
The outdoor temperature is between -3 and +43°C.
The water temperature is of 15°C minimum.
The evaporator at the rear/on the sides of the HP is clean (leaves, dust, pollen, cobwebs...)
You can now start your device by following, in the given order, the following steps:
Open the 3 valves of the bypass (refer to the hydraulic diagram).
Half-close the bypass valve.
Remove all unused items or tools from the area surrounding the HP.
Start the pump of the filtration system.
Power up the HP by engaging the circuit-breaker and using the ON/OFF button of the display.
Check that the HP starts and stops in sync with the filtration circuit: if no water is detected in the HP,
the display shows "FLO"
The HP starts after a delay of a few minutes.
Adjust the temperature ("Regulation" chapter).
Adjust the water flow ("Water flow setting" chapter).
After a few minutes, you can adjust the bypass valve as indicated in the "Water flow setting" chap-
ter. Having completed the above steps, cover the pool and let the HP operate for a few days with
the filtration pump in "forced mode" until the water of the pool reaches the desired bathing tem-
perature.

SETTINGS

Water flow setting:
To optimize the heating performance and achieve power savings, the flow of water travelling
through the HP should be adjusted.
The adjustment is done based on the reading of the adjustment pressure gauge. The adjustment is
done by opening or closing the adjustment valve of the bypass.
To increase the pressure on the front pressure gauge: reduce the amount of water passing through
the HP: open the bypass adjustment valve.
To reduce the pressure on the front pressure gauge: increase the amount of water passing through
the HP: close the bypass adjustment valve.
During normal operations, the inlet and outlet valves must remain fully open.
Normal pressure:
The flow of water through the HP and the fluid pressure in the device are intimately linked.
The flow value given for information purposes is of 5 to 7m³/h, i.e. approximately 100l/min to reach
the maximum heating power of the HP.
The ideal setting is achieved when the hand of the pressure gauge (for heating operations in MAX
mode) indicates a temperature in °C greater by 10 to 15°C than the current temperature of the
swimming pool.
Remember, the HP must operate for a few minutes before the pressure stabilizes on the pressure
gauge.
Example: the swimming pool water is 20°C, the HP has been operating for 5 minutes, and the hand
of the pressure gauge indicates 20 bars / 280 PSI / 32°C / 90°F. -> 32°C – 20°C = 12°C -> the set-
ting is right (between 10 and 15°C).
Abnormal pressure:
If the pressure at the pressure gauge is too high or too low, that means that the flow of water
through the HP is inadequate.
Action must therefore be taken by opening or closing progressively the bypass adjustment valve, to
get the pressure in the recommended range.
When stopped, the temperature reading should be close to the temperature of the swimming pool
water.
If the hand shows 0, the device should not be used (contact your distributor).
Setting frequency:
The flow through the HP depends much on water temperature, and to a lesser extent, on air tem-
