STARTING UP THE HEAT EXCHANGER
Once the exchanger is plumbed in and wired, do the following:
•
Start up the filtration pump and make sure that there are no leaks on the hydraulic circuit.
•
Open the isolating valves on the boiler's primary circuit.
•
Power up the heat exchanger. The digital display on the thermostat lights up, 888 blinks for a few
seconds, then the pool temperature is displayed.
•
Move the control switch to ʺOnʺ.
•
If the pool temperature is lower than the set point temperature, the indicator light on the switch is
illuminated indicating that the circulation pump is running.
Note :
The indicator light is only illuminated while the circulation pump is running. Therefore, while the pool
water is at the desired temperature, it is normal for the indicator light to be out although the switch is set
to ʺOnʺ.
Changing the temperature set point:
Press the ʺSETʺ key and hold it down (less than 4
seconds), the value of the set point is displayed.
The set point can be modified using the ʺUPʺ and
ʺDOWNʺ keys once the ʺSETʺ key is released.
To increase the desired temperature, press the
ʺUPʺ key, press the key repeatedly until the desired
temperature is displayed (maximum 45° C), then
press ʺSETʺ or wait 10 seconds.
To decrease the desired temperature, press the
ʺDOWNʺ key, press the key repeatedly until the
desired temperature is displayed (minimum 15° C),
then press ʺSETʺ or wait 10 seconds.
Once the desired set point is displayed, wait for a few seconds, the pool temperature will be displayed
again.
Note:
the default temperature setting is 15°C.

OPERATING CONTROLS
To ensure that the heat exchanger is running correctly:
•
Bring your ear close to the circulation pump, toggle the heat exchanger's On/Off switch, if the circulation
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 circulation 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 circulation pump starts up, replace the central stud.
If, despite performing the checks listed 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.
