I Operation - Zodiac Heat Line 20 Instructions For Installation And Use Manual

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.
• 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.
