7) Check that no ALARM code is displayed when the unit is ON (see
troubleshooting guide).
8)
Set the water flow rate using the by-pass valve (see Sections 3.6 and
2.1), as provided for on each model, to obtain a Entry/Exit temperature
difference of 2°C.
9) After running for a few minutes, check that the air exiting the unit is cool
(between 5 and 10°C).
10) With the unit operating, turn off the filter pump. The unit should turn off
automatically and display error code E03.
11) Run the unit and pool pump 24 hours a day until the desired water
temperature has been reached. When the set water inlet temperature is
reached, the unit will shut down. It will restart automatically (provided the
pool pump is running) if the pool temperature falls by 0.5°C below the set
temperature.
Flow rate controller - The unit is fitted with a flow rate controller that turns on
the heat pump when the pool filtration pump is running and turns it off if the
filtration pump is off. If the water is low, alarm code E03 is displayed on the
regulator (See Section 6.4).
Time delay - the unit incorporates a time delay of 3 minutes to protect
the control circuit components, eliminate any restart instability and any
switch mechanism interference. Thanks to this time delay, the unit restarts
automatically approximately 3 minutes after any loss of power to the control
circuit. Even a brief loss of power activates the restart time delay.
