Water Quality (Standard) - DESJOYAUX PISCINES JD PAC 8 Manual De Instrucciones

Winterisation
The following operations must be performed when winterising the heat pump:
• Stop the filtration.
• Turn the pump off.
• Drain the heat exchanger to prevent all frost damage.
To do this, drain all water from the exchanger's tank by disconnecting the
machine's inlet and outlet connections, then screw the connectors back on to
ensure that foreign elements do not enter the machine.
• Cover the heat pump with a waterproof tarp.
If you operate your filtration system over the winter period, the shut-off valves
must remain closed. Also, remain vigilant with regard to freezing
temperatures.

Water quality (Standard)

The recommended water quality standards must respect the following standards:
•
Chlorine concentration below 2.5 ppm
•
pH between 6.9 and 8
In the event of shock chlorination, turn the heat pump off and isolate it by
closing the inlet and outlet valves. After the treatment, open the valves to their
original positions and start the heat pump.
