OPERATING CONTROLS

To ensure that the heat exchanger is running correctly:
- Bring your ear close to the circulating pump, toggle the heat exchangers On/Off switch, if the circulating pump is
running correctly you should hear a low whistling coming from the pump motor.
- Place one hand on the inlet pipe of the primary circuit and the other on the outlet pipe of the primary circuit, you
should feel a noticeable temperature difference. A noticeable temperature difference indicates that there is an
efficient heat exchange between the primary and secondary circuits and, therefore, that the heat exchanger is
running correctly. The body of the heat exchanger should be cold or at most at the same temperature as the
pool.
- After a prolonged shut-down (winterizing), the circulating pump may fail to start up. To release it, unscrew the
central unscrew the central stud using a screw driver, rotate the shaft one way and then the other. Once the
circulating pump starts up, replace the central stud.
If, after carry out the above, the heat exchanger continues to malfunction this could be due to:
- Incorrect sizing of the primary circuit (pressure drop too high).
- Insufficient air purge of the primary circuit.
- Malfunction of the boiler's main thermostat (the water in the primary circuit is not hot enough).
- Under sizing of the boiler.
The display shows "PIl" and the heat exchanger is not running. Check the sensor connections or replace the
sensor.
WINTERIZING
- Cut the power supply to the heat exchanger accessories (circulating pump, thermostat, etc.)
- Prepare the filtration group for winterizing by draining the various lines.
- Carefully drain the secondary circuit lines, especially if the secondary circuit runs outside between the heat
exchanger and the filter.
- Drain the heat exchanger body (using the drain valve on the installation or by loosening one of the unions.
