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 setting 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 temperature. It should therefore be adjusted:
•
When the pump is started, and the water is cold;
•
During the rise of temperature;
•
When the desired temperature has been reached.
There should not be any reason to subsequently adjust the flow. An occasional reading of the pressure gauge to ensure everything is operating normally and
the flow remains unchanged is generally sufficient.
GENERAL USE
Water quality (standard):
The water quality standards must respect the following norms:
•
Chlorine concentration less than 2.5 ppm
•
pH between 6.9 and 8
•
In case of sudden chlorination, isolate the heat pump by shutting the inlet and outlet valves of the device, and reset them to their initial positions after
treatment.
Rise in temperature :
As soon as you want to put your pool into service at the beginning of the season:
• First isolate your heat pump from the filtration circuit:
• Close the upstream and downstream valves of the bypass.
• Fully open the adjusting valve.
• Carry out all the usual initial operations (filling, treatment, washing the filter, etc.).
• Turn on the filtration pump.
• Turn on the heat pump, set the temperature, open the valves and adjust the water flow.
• Cover the pelvis with isothermal cover.
• Allow the filtration pump and heat pump to run continuously until the desired temperature is reached (2 days to 1 week depending on climatic and geo-
graphical conditions).
Remember to adjust the flow rate during and at the end of the temperature rise.
The temperature rise time depends heavily on the exposure of the pool to the wind, sun and the nature of its environment.
