The heat exchanger must be drained to avoid the risk of freezing of any stagnant water, which
could damage its internal components; the titanium exchanger, the flow sensor, etc..
Never stop the heat pump during a thermodynamic defrosting phase or only after one, this could cause
problems when the heat pump is restarted at the beginning of a subsequent season (subsequent triggering of
the "HP" mechanism before the heat pump).
Trigger the switch in the electrical panel.
Disconnect the machine, wind up the cable and store it.
➢
Bleeding the heat exchanger
Close the by-pass valves to hydraulically isolate the machine.
Unscrew the upper coupling and then the lower coupling: the water will drain from the machine by gravity..

PROBLEM SOLVING
Heat pump is not powered (displays white)
•
Has the earth leakage circuit breaker protecting the heat pump become jammed?
•
Are the electrical connections (in the electric panel, connection box, etc.) correctly tightened?
La pompa di calore è alimentata (display accesa), ma non avviene nulla
all’avvio
•
The machine is in the resting phase (lasts 3 to 5 minutes)
•
Is the set point correct? Value entered correctly
•
Is filtration running?
The heat pump starts up but the earth leakage circuit breaker trips.
•
Is/are the earth leakage circuit breaker or thermal magnetic circuit breaker for the heat pump line
not of the D-curve type?
•
Has the permissible amperage of the main switch in the house or utility room been exceeded?
•
Is the amperage of the thermal protection of the line supplying the heat pump too low?
•
Is the house located at the end of the power supply line? If so, could a significant voltage drop at
start-up explain this phenomenon, etc.?
The heat pump is running, but does not heat the water properly
•
Check that the water is correctly heated as it flows through the heat pump (1 to 5°C depending on the model): if this
is the case, the water is correctly heated but the heat loss from the pool is too high (cold nights, pool not protected
by an isothermal cover, etc.).
•
The heat pump is undersized in relation to the volume of the pool.
•
The duration of the programmed daily filtration cycles is insufficient.
•
Check that the set point is correct
•
The air circulation through the evaporator may be obstructed: check that the minimum distances between the heat
pump and nearby obstacles have been respected
•
Check that the evaporator is free of moss, dust, pollen, etc. o Check that the air circulation through the evaporator is
not obstructed.
